Beyond Tables: New Directions in Spatial Interaction


Work on interactive tabletops and surfaces has focused mostly on two-dimensional issues, such as multi-finger gestures and tangible interaction in (mostly) horizontal settings. Interesting as it is however, this picture is missing several dimensions. I will describe work on both horizontal and vertical surfaces and present novel on-and-above-the-surface techniques based on bi-manual models to take advantage of the continuous interaction space for manipulations in 2D and 3D environments. I will also discuss means to allow for more expressive interactions, including novel uses of sound and combining hand and finger tracking in the space above the table with multitouch gestures as well as novel interaction contexts, such as vertical surfaces, two-sided displays and mobile settings. These combinations can provide alternative design environments and allow novel interaction modalities.
