Interactive phone call: synchronous remote collaboration and projected interactive surfaces

Back when I was a research associate at Uni Duisburg-Essen, I helped out on a project exploring the use of personal projector phones. Smartphones provide a large amounts of personal data, functionalities, and apps and make a substantial part of our daily communication. But during phone calls the phone cannot be used much beyond voice communication and does not offer support for synchronous collaboration. This is owed to the fact that first, despite the availability of alternatives, the phone is typically held at one’s ear; and second that the small mobile screen is less suited to be used with existing collaboration software. This project presented a novel in-call collaboration system that leverages projector phones as they provide a large display that can be used while holdong the phone to the ear to project an interactive interface anytime and anywhere.
