Interacting with Wall-Size Screens

When attempting to transfer the main interaction paradigms involving mouse, pen, and touch from the desktop to large screens many of them “break”. The sheer size of wall-size displays caused users to lose track of the mouse pointer. When using touch or pen input, the screen size makes it hard to reach distant screen content. And those techniques that seem to transfer, now often suffer from limited accuracy, caused by the inferior tracking that many of the large displays offer. I am describing a series of research projects that address these problems. ACM Classification
