Airborne Mouse
edpin writes "CNN is reporting this new mouse that works without a surface. You hold the device in your hand and tilt it to where on screen you want it to go. It uses a similar technique to "rock and scroll" developed by Compaq (now HP) a while ago."
But is this really any more accurate than, say, a joystick? The advantage of a mouse is that mouse movements by your hand map directly to your screen. With practice you can just move it and get very close to the desired point. A joystick like device lets you control the rate of change of pointer position, not the position directly itself. While useful for some things, for aiming my railgun or getting work done this gadget is junk.
Several years ago, Till Harbaum added a tilt sensor to his Palm Pilot. Then he wrote Mulg, which is kinda like Marble Madness; if you have the sensor, you can play by tilting the Palm to roll the marble around.
This is STILL the all-time best Palm HW hack I've ever seen.
