The AMIDA Mobile Meeting Assistant is a system that allows remote participants to attend a meeting through a mobile device. The system improves the engagement in the meeting of the remote participants with respect to voiceonly solutions thanks to the use of visual annotations and the capture of slides. The visual focus of attention of meeting participants and other annotations serve to reconstruct a 2D or a 3D representation of the meeting on a mobile device (smart phone). A first version of the system has been implemented, and feedback from a user study and from industrial partners shows that the Mobile Meeting Assistant's functionalities are positively appreciated, and sets priorities for future developments.
