In this data release from the ongoing LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) we present 120-168 MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at approximately 12h45m +44◦30′ and 1h00m +28◦ 00′ and spanning 4178 and 1457 square degrees respectively. The images were derived from 3,451 hrs (7.6 PB) of LOFAR High Band Antenna data which were corrected for the direction-independent instrumental properties as well as direction-dependent ionospheric distortions during extensive, but fully automated, data processing. A catalogue of 4,396,228 radio sources is derived from our total intensity (Stokes I) maps, where the majority of these have never been detected at radio wavelengths before. At 6′′ resolution, our full bandwidth Stokes I continuum maps with a central frequency of 144 MHz have: a median rms sensitivity of 83 μ Jy/beam; a flux density scale accuracy of approximately 10%; an astrometric accuracy of 0.2′′; and we estimate the point-source completeness to be 90% at a peak brightness of 0.8 mJy/beam. By creating three 16 MHz bandwidth images across the band we are able to measure the in-band spectral index of many sources, albeit with an error on the derived spectral index of > ±0.2 which is a consequence of our flux-density scale accuracy and small fractional bandwidth. Our circular polarisation (Stokes V) 20′′ resolution 120-168 MHz continuum images have a median rms sensitivity of 95 μ Jy/beam, and we estimate a Stokes I to Stokes V leakage of 0.056%. Our linear polarisation (Stokes Q and Stokes U) image cubes consist of 480 97.6 kHz wide planes and have a median rms sensitivity per plane of 10.8mJy/beam at 4′ and 2.2mJy/beam at 20′′; we estimate the Stokes I to Stokes Q/U leakage to be approximately 0.2%. Here we characterise and publicly release our Stokes I, Q, U and V images in addition to the calibrated uv-data to facilitate the thorough scientific exploitation of this unique dataset.

We describe the design, fabrication, and laboratory-demonstration of a novel dual-polarized multichroic antenna-coupled Transition Edge Sensor (TES) bolometer. Each pixel separates the incident millimeter radiation into two linear polarization channels as well as several frequency channels (bands). This technology enables us to realize bolometer arrays for Cosmic Microwave Background (CMB) polarimetry measurements that map the sky at multiple colors while simultaneously boosting the optical throughput over what would have been attained from arrays of single-frequency channel detectors. Observations at multiple frequency channels are important for differentiating polarized galactic foregrounds and atmospheric fluctuations from the CMB.Each pixel couples free-traveling radiation onto lithographed microstrip transmission lines prior to the bolometers using a dual-polarized broadband antenna known as a sinuous antenna. The transmission lines are integrated onto the back of the antenna arms and the antennas are in direct contact with an extended-hemispherical lens. We show measurements of scale model (4-12GHz) and to-scale (80-240Hz) antennas to demonstrate high antenna-gain, low cross-polarization contamination, and efficient coupling over a 1-2 octave bandwidth.We have developed microstrip circuits that divide the antenna's wide bandwidth into smaller channels. In one scheme, two or three frequency channels can be extracted from the antenna's received power using microstrip circuits known as diplexers and triplexers. These avoid atmospheric spectral lines and are well suited to terrestrial observations. We can also partition this bandwidth into contiguous bands using cochlear channelizers inspired by the physiology of the human ear; this design is most advantageous for satellite missions where there are no concerns about atmospheric contamination. We present design methodologies for these circuits and show measurements of prototypes coupled to TES bolometers to verify acceptable performance. We also describe the fabrication of a broadband anti-reflection coating for the contacting lenses and demonstrate that lens-coupled sinuous pixels receive more power with the coatings than without. Finally, we remark on the last un-resolved challenge of forming symmetric beams and balun designs that may help form patterns more useful for polarimetry.This technology is a candidate for use in the Polarbear ground-based experiment. By packing more detectors into the focal-plane than can be done with monochromatic pixels, multichroic pixels will allow Polarbear to map the sky much faster. This technology is also candidate for future space-based missions as well, where multhchroic pixels will allow a less massive payload and hence a lower cost mission. Finally, we envision using arrays of similar pixels in sub-millimeter observations of high-redshift galaxy clusters as well (e.g.example Sunyaev-Zeldovich Effect measurements). However, we require more sophisticated lithography and etching techniques to shrink these pixels to a size suitable for such wavelengths.

This research aims to study brand identity and food packaging. The objective of this study is to create a solid visual identity and packaging design for a new food brand of K-citymarket, Järven-pää, Finland. This research is a part of a project assigned during my internship at Pentagon Design. To achieve the research objectives, I studied previous literature and research on the definitions of brand and why it is important to build a brand image. Furthermore, I conducted research on psychology-based brand building, a design approach that suits best for this project according to the client’s needs. In this research, besides the theories of building a brand based on psychology that have been applied during the design process, it is also important to understand the actual working process by Discover – Define – Design- Deliver from Pentagon Design and how to apply it during the entire project. The outcome of the work is an authentic yet flexible brand identity fundamental, which will, in the future, have an umbrella effect that links all kinds of food together with an iden-tical heart-shaped logo.

Country: PortugalEm Portugal, as denúncias de assédio sexual cresceram 59% entre 2014 a 2017 (Associação Portuguesa de Apoio à Vítima (APAV), 2018). Na sequência deste crescimento torna-se pertinente a criação de uma plataforma que venha dar uma voz maior a estas vítimas e que, em modo de intervenção e advertência, construa caminho para uma maior e mais aberta discussão sobre este tão importante tema. Com o fim de quebrar o muro psicologicamente estabelecido entre vítima e observador, o propósito deste projeto é o desenvolvimento de uma curta-metragem imersiva, “Just a Compliment”, que a partir das técnicas de Realidade Virtual e Narrativas Imersivas desenvolva uma narrativa em torno do seu utilizador, aproximando-o destes casos através do conhecimento empírico assim estabelecido. “Just a Compliment” é uma curta-metragem imersiva que retrata várias situações de assédio a partir do ponto-de-vista na primeira pessoa (1st Person Point-of-View), colocando o utilizador no papel da vítima e visando estabelecer uma relação entre a o observador e as situações representadas. A partir das técnicas de vídeo 360° e posicionando o utilizador no centro da ação enquanto personagem principal da experiência, procura-se assim a imersão do mesmo na narrativa. Estabelecida uma narrativa dentro do tema do assédio sexual, o objetivo será então a advertência e sensibilização dos seus utilizadores para estas situações. A partir de uma investigação conduzida sobre a temática em questão, a peça é montada visando a representação fiel de episódios reais. Pretende-se com isto que, após a visualização da curtametragem, o utilizador consiga ter uma aproximação e empatia maior pelas vítimas que passam por estas situações, bem como uma sensibilidade acrescida à temática. Link para a curta-metragem Just a Compliment: https://youtu.be/cAlDlUTyh54 In Portugal, sexual harassment complaints rose 59% between 2014 and 2017 (Associação Portuguesa de Apoio à Vítima (APAV), 2018). Following this growth, it becomes pertinent to create a platform that provides a louder voice to these victims and that, in the form of intervention and warning, builds the way for a greater and more open discussion on this very important topic. In order to break the psychologically established wall between victim and observer, the purpose of this project is the development of an immersive short film, “Just a Compliment”, which develops a narrative around its user by applying the techniques of Virtual Reality and Immersive Narratives, bringing him/her closer to these cases through the empirical knowledge thus established. “Just a Compliment” is an immersive short film that portrays various situations of harassment from the first-person point of view (1st Person Point-of-View), placing the user in the role of the victim and aiming to establish a relationship between the observer and the situations represented. Based on 360° video techniques and placing the user at the center of the action as the main character of the experience, the purpose is to immerse the user in the narrative. Having established a narrative on the topic of sexual harassment, the goal will then be to warn and raise awareness among its users about these situations. Based on an investigation conducted on the subject in question, the play is assembled with a view to faithfully representing real episodes. It is intended with this that, after viewing the short film, the user will be able to have a greater approach and empathy for the victims who go through these situations, as well as an increased sensitivity to the theme.

Maternal consumption of alcohol during pregnancy can induce a range of behavioral and cognitive deficits in offspring, which are collectively termed Fetal Alcohol Spectrum Disorders (FASD). There are significant delays in motor development and sensory-motor skills in children with FASD, but the underlying neurobiological mechanisms of these deficits are poorly understood. The goal of this research project is to test the hypothesis that the Kinesiological Instrument for Normal and Altered Reaching Movements (KINARM) will serve as an effective tool for identifying and measuring specific, neurologically-based motor deficits in children with FASD. These deficits were revealed through investigation of multi-joint upper limb movements during the performance of sensory-motor tasks. Children (31 FASD; 83 controls, aged 5 to 18 years, male and female) performed: (1) a visually-guided reaching task with fingertip feedback only; and children (31 FASD; 49 controls, aged 5 to 18 years, male and female) performed: (2) an arm position-matching task in the absence of visual feedback. Children with FASD differed significantly from controls in many reaching task outcome measures, specifically those related to the initial motor response and corrective responses. In particular, large effect sizes were observed for outcome measures related to the first (initial) movement (corresponding to feedforward control; e.g., direction error; distance error), as well as for those measures related to corrective responses (corresponding to feedback control; e.g., difference between minimum and maximum hand speeds; number of speed peaks during movement). In the position-matching task, children with FASD constricted the spatial workspace of the subject-controlled arm relative to the robot-controlled arm, in the horizontal axis. There was also observed a systematic shift between the subject- and robot-controlled arms in the XY end position, resulting in significant error. Additionally, children with FASD exhibited significantly increased trial-to-trial variability for final hand position of the subject-controlled arm, over all targets, and for which large effect sizes were observed. The results suggest that children with FASD have difficulty integrating sensory information into planned motor movements. The KINARM is a promising research tool that may be used to assess motor control deficits in children affected by prenatal exposure to alcohol.

In relation to the ongoing refugee crisis caused by the Syrian war, Red Cross has created the campaign ”Sense of Home”. This campaign creates an experience through virtual reality, which allows the user to meet refugees in a Lebanese refugee camp.Our interest lies in virtual reality as a communicative tool and the potential for communicating humanitarian purposes through this medium in respect to “Sense of Home”; one of the main attributes of virtual reality is the ability to create a more sensuous experience compared to traditional media and so it has the potential of forming empathy with the receiver.In order to understand the potential and limitations of virtual reality, we investigate what constitutes a successful virtual reality experience and how this success is exploited through the Red Cross campaign. This is also examined from a campaign theoretical approach in which we analyse how the experience meets the goals and purposes of the sender.Inspired by the field of autoethnography, we include an analysis based on our own experiences of Red Cross’ virtual reality campaign as well as analyzing the experiences of the target group retrieved via short interviews.Finally, we include a discussion section that debates the limitations of virtual reality based on the Red Cross campaign concerning exponential reach as well as the narrative choices. Additionally, we discuss in a larger perspective the strategic choices Red Cross has conducted in their campaign based on the hypotheses from Yang and Saffer’s (2018) article that proposes how NGO’s can communicate effectively about this particular issue.Our thesis is concluded with our assessment of virtual reality as a communicative tool for the Red Cross campaign.

The CGView Server generates graphical maps of circular genomes that show sequence features, base composition plots, analysis results and sequence similarity plots. Sequences can be supplied in raw, FASTA, GenBank or EMBL format. Additional feature or analysis information can be submitted in the form of GFF (General Feature Format) files. The server uses BLAST to compare the primary sequence to up to three comparison genomes or sequence sets. The BLAST results and feature information are converted to a graphical map showing the entire sequence, or an expanded and more detailed view of a region of interest. Several options are included to control which types of features are displayed and how the features are drawn. The CGView Server can be used to visualize features associated with any bacterial, plasmid, chloroplast or mitochondrial genome, and can aid in the identification of conserved genome segments, instances of horizontal gene transfer, and differences in gene copy number. Because a collection of sequences can be used in place of a comparison genome, maps can also be used to visualize regions of a known genome covered by newly obtained sequence reads. The CGView Server can be accessed at http://stothard.afns.ualberta.ca/cgview_server/

Nowadays, with the advance of biomedical and pharmaceutical technology, new treatments such as cell therapy, cell sheets, etc. all provide patients other alternatives. However, the public has little knowledge in these new technologies and they also find them difficult to understand. Hence, this paper is aimed at providing the public with state-of-the-art technological knowledge and constructing an innovative field full of diversity, entertainment, and educational meaning with the assistance of Augmented Reality (AR) and Virtual Reality (VR). Taking the cell sheets technology, a kind of cell therapy recently approved in Taiwan, as an example, we built an AR platform, and demonstrated a trailer animation, 2D animation and 3D model animation via Merge Cube. The trailer animation will portrait how the main character helps her friend, who became physically challenged in an accident, stand up again by asking a genius doctor to perform cell sheet technology. The 2D animation will be used to explain how cell sheet works and its application, while the 3D animation helps demonstrate the DNA reproduction and cell division in cell therapy. A VR field will also be set up so that players can play as the genius doctor, fight their way through the VR games, and learn more about cell sheet technology. To let the public learn more about this biotechnology knowledge, we held an exhibition to display the research results, providing them a whole new learning experience.

This technology enables us to realize bolometer arrays for Cosmic Microwave Background (CMB) polarimetry measurements that map the sky at multiple colors while simultaneously boosting the optical throughput over what would have been attained from arrays of single-frequency channel detectors. Observations at multiple frequency channels are important for differentiating polarized galactic foregrounds and atmospheric fluctuations from the CMB.Each pixel couples free-traveling radiation onto lithographed microstrip transmission lines prior to the bolometers using a dual-polarized broadband antenna known as a sinuous antenna. The transmission lines are integrated onto the back of the antenna arms and the antennas are in direct contact with an extended-hemispherical lens. We show measurements of scale model (4-12GHz) and to-scale (80-240Hz) antennas to demonstrate high antenna-gain, low cross-polarization contamination, and efficient coupling over a 1-2 octave bandwidth.We have developed microstrip circuits that divide the antenna's wide bandwidth into smaller channels. In one scheme, two or three frequency channels can be extracted from the antenna's received power using microstrip circuits known as diplexers and triplexers. These avoid atmospheric spectral lines and are well suited to terrestrial observations. We can also partition this bandwidth into contiguous bands using cochlear channelizers inspired by the physiology of the human ear; this design is most advantageous for satellite missions where there are no concerns about atmospheric contamination. We present design methodologies for these circuits and show measurements of prototypes coupled to TES bolometers to verify acceptable performance. We also describe the fabrication of a broadband anti-reflection coating for the contacting lenses and demonstrate that lens-coupled sinuous pixels receive more power with the coatings than without. Finally, we remark on the last un-resolved challenge of forming symmetric beams and balun designs that may help form patterns more useful for polarimetry.This technology is a candidate for use in the Polarbear ground-based experiment. By packing more detectors into the focal-plane than can be done with monochromatic pixels, multichroic pixels will allow Polarbear to map the sky much faster. This technology is also candidate for future space-based missions as well, where multhchroic pixels will allow a less massive payload and hence a lower cost mission. Finally, we envision using arrays of similar pixels in sub-millimeter observations of high-redshift galaxy clusters as well (e.g.example Sunyaev-Zeldovich Effect measurements). However, we require more sophisticated lithography and etching techniques to shrink these pixels to a size suitable for such wavelengths.

In this data release from the ongoing LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) we present 120-168 MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at approximately 12h45m +44◦30′ and 1h00m +28◦ 00′ and spanning 4178 and 1457 square degrees respectively. The images were derived from 3,451 hrs (7.6 PB) of LOFAR High Band Antenna data which were corrected for the direction-independent instrumental properties as well as direction-dependent ionospheric distortions during extensive, but fully automated, data processing. A catalogue of 4,396,228 radio sources is derived from our total intensity (Stokes I) maps, where the majority of these have never been detected at radio wavelengths before. At 6′′ resolution, our full bandwidth Stokes I continuum maps with a central frequency of 144 MHz have: a median rms sensitivity of 83 μ Jy/beam; a flux density scale accuracy of approximately 10%; an astrometric accuracy of 0.2′′; and we estimate the point-source completeness to be 90% at a peak brightness of 0.8 mJy/beam. By creating three 16 MHz bandwidth images across the band we are able to measure the in-band spectral index of many sources, albeit with an error on the derived spectral index of > ±0.2 which is a consequence of our flux-density scale accuracy and small fractional bandwidth. Our circular polarisation (Stokes V) 20′′ resolution 120-168 MHz continuum images have a median rms sensitivity of 95 μ Jy/beam, and we estimate a Stokes I to Stokes V leakage of 0.056%. Our linear polarisation (Stokes Q and Stokes U) image cubes consist of 480 97.6 kHz wide planes and have a median rms sensitivity per plane of 10.8mJy/beam at 4′ and 2.2mJy/beam at 20′′; we estimate the Stokes I to Stokes Q/U leakage to be approximately 0.2%. Here we characterise and publicly release our Stokes I, Q, U and V images in addition to the calibrated uv-data to facilitate the thorough scientific exploitation of this unique dataset. This is field P171+60.

This research aims to study brand identity and food packaging. The objective of this study is to create a solid visual identity and packaging design for a new food brand of K-citymarket, Järven-pää, Finland. This research is a part of a project assigned during my internship at Pentagon Design. To achieve the research objectives, I studied previous literature and research on the definitions of brand and why it is important to build a brand image. Furthermore, I conducted research on psychology-based brand building, a design approach that suits best for this project according to the client’s needs. In this research, besides the theories of building a brand based on psychology that have been applied during the design process, it is also important to understand the actual working process by Discover – Define – Design- Deliver from Pentagon Design and how to apply it during the entire project. The outcome of the work is an authentic yet flexible brand identity fundamental, which will, in the future, have an umbrella effect that links all kinds of food together with an iden-tical heart-shaped logo.

Country: PortugalEm Portugal, as denúncias de assédio sexual cresceram 59% entre 2014 a 2017 (Associação Portuguesa de Apoio à Vítima (APAV), 2018). Na sequência deste crescimento torna-se pertinente a criação de uma plataforma que venha dar uma voz maior a estas vítimas e que, em modo de intervenção e advertência, construa caminho para uma maior e mais aberta discussão sobre este tão importante tema. Com o fim de quebrar o muro psicologicamente estabelecido entre vítima e observador, o propósito deste projeto é o desenvolvimento de uma curta-metragem imersiva, “Just a Compliment”, que a partir das técnicas de Realidade Virtual e Narrativas Imersivas desenvolva uma narrativa em torno do seu utilizador, aproximando-o destes casos através do conhecimento empírico assim estabelecido. “Just a Compliment” é uma curta-metragem imersiva que retrata várias situações de assédio a partir do ponto-de-vista na primeira pessoa (1st Person Point-of-View), colocando o utilizador no papel da vítima e visando estabelecer uma relação entre a o observador e as situações representadas. A partir das técnicas de vídeo 360° e posicionando o utilizador no centro da ação enquanto personagem principal da experiência, procura-se assim a imersão do mesmo na narrativa. Estabelecida uma narrativa dentro do tema do assédio sexual, o objetivo será então a advertência e sensibilização dos seus utilizadores para estas situações. A partir de uma investigação conduzida sobre a temática em questão, a peça é montada visando a representação fiel de episódios reais. Pretende-se com isto que, após a visualização da curtametragem, o utilizador consiga ter uma aproximação e empatia maior pelas vítimas que passam por estas situações, bem como uma sensibilidade acrescida à temática. Link para a curta-metragem Just a Compliment: https://youtu.be/cAlDlUTyh54 In Portugal, sexual harassment complaints rose 59% between 2014 and 2017 (Associação Portuguesa de Apoio à Vítima (APAV), 2018). Following this growth, it becomes pertinent to create a platform that provides a louder voice to these victims and that, in the form of intervention and warning, builds the way for a greater and more open discussion on this very important topic. In order to break the psychologically established wall between victim and observer, the purpose of this project is the development of an immersive short film, “Just a Compliment”, which develops a narrative around its user by applying the techniques of Virtual Reality and Immersive Narratives, bringing him/her closer to these cases through the empirical knowledge thus established. “Just a Compliment” is an immersive short film that portrays various situations of harassment from the first-person point of view (1st Person Point-of-View), placing the user in the role of the victim and aiming to establish a relationship between the observer and the situations represented. Based on 360° video techniques and placing the user at the center of the action as the main character of the experience, the purpose is to immerse the user in the narrative. Having established a narrative on the topic of sexual harassment, the goal will then be to warn and raise awareness among its users about these situations. Based on an investigation conducted on the subject in question, the play is assembled with a view to faithfully representing real episodes. It is intended with this that, after viewing the short film, the user will be able to have a greater approach and empathy for the victims who go through these situations, as well as an increased sensitivity to the theme.

Maternal consumption of alcohol during pregnancy can induce a range of behavioral and cognitive deficits in offspring, which are collectively termed Fetal Alcohol Spectrum Disorders (FASD). There are significant delays in motor development and sensory-motor skills in children with FASD, but the underlying neurobiological mechanisms of these deficits are poorly understood. The goal of this research project is to test the hypothesis that the Kinesiological Instrument for Normal and Altered Reaching Movements (KINARM) will serve as an effective tool for identifying and measuring specific, neurologically-based motor deficits in children with FASD. These deficits were revealed through investigation of multi-joint upper limb movements during the performance of sensory-motor tasks. Children (31 FASD; 83 controls, aged 5 to 18 years, male and female) performed: (1) a visually-guided reaching task with fingertip feedback only; and children (31 FASD; 49 controls, aged 5 to 18 years, male and female) performed: (2) an arm position-matching task in the absence of visual feedback. Children with FASD differed significantly from controls in many reaching task outcome measures, specifically those related to the initial motor response and corrective responses. In particular, large effect sizes were observed for outcome measures related to the first (initial) movement (corresponding to feedforward control; e.g., direction error; distance error), as well as for those measures related to corrective responses (corresponding to feedback control; e.g., difference between minimum and maximum hand speeds; number of speed peaks during movement). In the position-matching task, children with FASD constricted the spatial workspace of the subject-controlled arm relative to the robot-controlled arm, in the horizontal axis. There was also observed a systematic shift between the subject- and robot-controlled arms in the XY end position, resulting in significant error. Additionally, children with FASD exhibited significantly increased trial-to-trial variability for final hand position of the subject-controlled arm, over all targets, and for which large effect sizes were observed. The results suggest that children with FASD have difficulty integrating sensory information into planned motor movements. The KINARM is a promising research tool that may be used to assess motor control deficits in children affected by prenatal exposure to alcohol.

In relation to the ongoing refugee crisis caused by the Syrian war, Red Cross has created the campaign ”Sense of Home”. This campaign creates an experience through virtual reality, which allows the user to meet refugees in a Lebanese refugee camp.Our interest lies in virtual reality as a communicative tool and the potential for communicating humanitarian purposes through this medium in respect to “Sense of Home”; one of the main attributes of virtual reality is the ability to create a more sensuous experience compared to traditional media and so it has the potential of forming empathy with the receiver.In order to understand the potential and limitations of virtual reality, we investigate what constitutes a successful virtual reality experience and how this success is exploited through the Red Cross campaign. This is also examined from a campaign theoretical approach in which we analyse how the experience meets the goals and purposes of the sender.Inspired by the field of autoethnography, we include an analysis based on our own experiences of Red Cross’ virtual reality campaign as well as analyzing the experiences of the target group retrieved via short interviews.Finally, we include a discussion section that debates the limitations of virtual reality based on the Red Cross campaign concerning exponential reach as well as the narrative choices. Additionally, we discuss in a larger perspective the strategic choices Red Cross has conducted in their campaign based on the hypotheses from Yang and Saffer’s (2018) article that proposes how NGO’s can communicate effectively about this particular issue.Our thesis is concluded with our assessment of virtual reality as a communicative tool for the Red Cross campaign.

The CGView Server generates graphical maps of circular genomes that show sequence features, base composition plots, analysis results and sequence similarity plots. Sequences can be supplied in raw, FASTA, GenBank or EMBL format. Additional feature or analysis information can be submitted in the form of GFF (General Feature Format) files. The server uses BLAST to compare the primary sequence to up to three comparison genomes or sequence sets. The BLAST results and feature information are converted to a graphical map showing the entire sequence, or an expanded and more detailed view of a region of interest. Several options are included to control which types of features are displayed and how the features are drawn. The CGView Server can be used to visualize features associated with any bacterial, plasmid, chloroplast or mitochondrial genome, and can aid in the identification of conserved genome segments, instances of horizontal gene transfer, and differences in gene copy number. Because a collection of sequences can be used in place of a comparison genome, maps can also be used to visualize regions of a known genome covered by newly obtained sequence reads. The CGView Server can be accessed at http://stothard.afns.ualberta.ca/cgview_server/

Nowadays, with the advance of biomedical and pharmaceutical technology, new treatments such as cell therapy, cell sheets, etc. all provide patients other alternatives. However, the public has little knowledge in these new technologies and they also find them difficult to understand. Hence, this paper is aimed at providing the public with state-of-the-art technological knowledge and constructing an innovative field full of diversity, entertainment, and educational meaning with the assistance of Augmented Reality (AR) and Virtual Reality (VR). Taking the cell sheets technology, a kind of cell therapy recently approved in Taiwan, as an example, we built an AR platform, and demonstrated a trailer animation, 2D animation and 3D model animation via Merge Cube. The trailer animation will portrait how the main character helps her friend, who became physically challenged in an accident, stand up again by asking a genius doctor to perform cell sheet technology. The 2D animation will be used to explain how cell sheet works and its application, while the 3D animation helps demonstrate the DNA reproduction and cell division in cell therapy. A VR field will also be set up so that players can play as the genius doctor, fight their way through the VR games, and learn more about cell sheet technology. To let the public learn more about this biotechnology knowledge, we held an exhibition to display the research results, providing them a whole new learning experience.
