We present COMMIT (Collaborative MultiMedia Interactive Table), a collaborative multimedia environment for remote group interaction. COMMIT enables collaboration among people at different locations by allowing them to not only share multimedia objects such as images, PDFs and videos, but also co-operate on these cyber objects. COMMIT is also motivated by the emerging Internet of Things (IoT), and provides a team-thing interface which supports the sharing of data streams from physical IoT objects, such as IP cameras. It enables collaborators to more effectively exploit huge volumes of valuable IoT data. COMMIT has been evaluated using real-life scenarios with random users. Feedback from our user study shows that COMMIT is intuitive and can aid group interactions in collaborative tasks requiring the Internet of Things.
