This deliverable describes the architectural aspects, components and features of the ImAc player. The different pieces of software that make up the player, together with the necessary steps to make it running, are also explained. Finally, the deliverable explains the different screens, User Interfaces (UIs), menus and interaction controls available in the player for the personalized presentation of contents. This is the second and final iteration of D3.5, after a first version delivered in M09 focused on single screen scenarios and presentation of immersive contents, subtitles and sign language videos, which was used in the first pilot phase. This final version includes improvements based on the feedback from the first pilot phase (specified as new WP2 requirements) as well as features that were planned for the second year of the project. Some examples of the latter include a more responsive and attractive UI, more mature voice control features, and support for multi-screen scenarios and embedding features into external websites.
