Abstract: Wall-sized displays are extremely valuable in many fields for visualizing complex processes and large quantities of data, as well as facilitating active collaboration among users. This research project is aimed at developing technologies for cre- ating display walls easily with inexpensive portable equipment, and dramatically enhancing these display walls by allowing users to naturally interact with the dis- plays as well as having the displays proactively adapt to users. These interactive display walls are implemented using multiple cost-effective video cameras and ultra-portable computer projectors, circumventing the need for special, expen- sive and cumbersome equipment. In this report, we document the achievements made during the course of the research project, and describe some of the ma- jor research and development work carried out. These include (i) a display wall based on casually-placed projectors, (ii) virtual persistent displays that are able to dynamically eliminate shadows cast by users blocking the projectors, and (iii) a framework for detecting and recognizing symbolic hand gestures. These research efforts are backed by interesting demonstrable research systems. Future research directions and subsequent deliverables are discussed at the end of the report.
