Two in the hand
Wow–now this you don’t see every day. A small company called Tactiva has unveiled a rather eye-popping demo of a device that lets you use both hands while working in design software.
The appeal of using two hands at once (instead of essentially pointing with a stick and grunting, as is done with a mouse) isn’t new; the latest Wacom tablets feature touch strips for non-dominant hand work, and Logitech and others sell a variety of pucks and other devices for the same purpose. But the Tactiva device takes things to a new level by displaying a ghosted image of your actual hands overlaid on the UI, as well as providing force feedback when you interact with on-screen objects.
The device faces plenty of obstacles to adoption (no manufacturers yet, potential $1000 price point, need for support in applications that assume a single input control). Yet I keep thinking about it.
What do you think? Just a neat parlor trick, or the future of computing, or something in between?
