Touch location information is determined independently for each user, allowing each touch on a common surface to be associated with a particular user. The surface generates location dependent, modulated electric fields which are capacitively coupled through the users to receivers installed in the work environment. We describe the design of these systems and their applications. Finally, we present results we have obtained with a small prototype device.

Using IMUs to Identify Supervisors on Touch Devices

“…In DiamondTouch [7] sensors are embedded in the chairs of users. In conjunction with a transmitter built into the display it is possible to identify the owner of each touch event.…”

Iterative design and evaluation of an event architecture for pen-and-paper interfaces

“…Through three projects (~19 Java classes each) involving a touch-sensitive digital table [8], we learned the importance of supporting multiple users, coordinating multiple devices, and translating between multiple coordinate systems.…”

“…To enable this, PaperToolkit captures input from multiple pens, and provides a penID in PenEvents (similar to [8,13]). …”

Reproducing and Re-experiencing the Writing Process in Japanese Calligraphy

“…We use MERL's DiamondTouch (DT) table [4] to sense the calligraphy activity produced in the natural setting where a user writes with a traditional brush with ink, on a sheet of paper placed on the flat surface of the DT table (Figure 1(a)). Our idea is to use water, more specifically, ink loaded in a brush tuft, as the conductive material between the brush and the DT surface.…”
