  Developed at Sony CSL. A computer augmented environment allowing for spatially continuous operations across portable computers, table and wall displays, and other physical objects (videotapes, document folders, etc.). A window on a portable computer jumps out onto a table display (Hyperdragging) and the other way around. Pick and Drop operations can be done using Laser pointers. Digital Attachment links physical object like book pages to related digital objects. PropCamera on a table display creates 3D views on a wall display.

However, it may be a good "always ON" kind of output device that calls for users' attention when necessary. Also, like vibrating cell phones, it may not bother other people. This may be a display device that people could use while driving a car.

When two points are pressed at the same time, the system recognizes the middle point between the two points -- this makes it difficult to create a single-device groupware systems using this device. Other companies' devices have similar restrictions regarding multi-person inputs on a single device. For example, SoftBoard gives DSP Error when two points are pressed simultaneously. )
