My answer for this is: The object in you hand gives you tactile feedback of *an object*. This means you can slightly rotate the object and have a good idea of its rotation just from tactile sense. The object rotation comes from finger abduction/adduction, not whole-hand rotation. > a pinching gesture makes sense (picking up objects, for instance), A good power-grip example. What other operations are there? It seems that you get to make your device choice once, and then the interaction follows. Given pinch glove, what can you do in addition to pickup, drop and Thwip!!! (Spider-man). > The Head Crusher interaction technique is a lot more fun with the gloves. They're ideally matched. -- Chris Shaw University of Regina cdshaw@cs.URegina.ca Assistant Professor http://www.cs.uregina.ca/~cdshaw
