The mobile phone devices are still developing and they are gaining more functionality and are able to deal with more advanced tasks. One of the technologies timidly trying to approach the mobile phone market is the augmented reality, which does no longer require external equipment to be formed in a programming application. There is a limited number of sources trying to describe the accuracy of augmented reality applications implemented on mobile devices. Within this study an application of augmented reality visualising virtual models of buildings was implemented on a mobile phone device in order to evaluate the rate of the device explication. Several tests were conducted to evaluate the application total accuracy. The implemented application was visualising virtual models of the real existing buildings displaying them in the same place the original buildings were. The final position was calculated by the application and the discrepancy of the view between the model and the real building was measured. The results were gathered revealing the application’s real accuracy. For the purposes of this study the functional application of augmented reality has been created. The application was implemented on the mobile phone. The results of the application formed the tables with final measurements of accuracy. Also several photographs were taken from the areas of the real existing buildings. Transferring the functionality of augmented reality from the external devices to mobile phones is possible with some harm to the application accuracy. Visualising building models is one of the possible extensions of the mobile phone market. The improvements in Global Positioning System would significantly improve the application´s general accuracy.
The augmented reality represents one of the most current approach in implementing the artificial reality. Primarily required large extensive head-mounted-displays now follows the trend of minimising the necessary equipment. The study shows how is it done that a single mobile phone can be used as a device creating a new reality and also answers what calculations are required by such a system setting the augmented environment. Also a problem of mobile phone’s augmented reality systems accuracy is developed in reference to the commonly proclaimed 2-metres inaccuracy of the GPS device.
