Ubiquitous Displays

Imagine a world in which people can use their handheld mobile devices to project and transfer content. Everyone can join the collaboration by simply bringing their mobile devices close to each other. People can grab data from each others' devices with simple hand gestures. Now imagine a large display created by tiling multiple displays where multiple users can interact with a large dynamically changing data set in a collocated, collaborative setting and the displays will take care of the data transfer and handling functions in a way that is transparent to the users.

We are working on several challenges in building ubiquitous displays including but not limited to:

1.      Geometric Registration

2.      Color Seamlessness

3.      Distributed Interaction
