Microsoft Research Shows Off Multi-Touch Mouse Prototypes
Engadget has snagged some of the details behind a bunch of multi-touch mouse prototypes from Microsoft Research. The prototypes range from the wacky to the extreme, but at least they are thinking outside the mouse trap. "Each one uses a different touch detection method, and at first glance all five seem to fly in the face of regular ergonomics. The craziest two are probably "Arty," which has two articulated arms to cradle your thumb and index finger, with each pad housing its own optical sensor for mission-critical pinching gestures, and "Side Mouse" which is button free and actually detects finger touches in the table immediately in front of the palm rest. Of course, there's plenty of crazy in the FTIR, Orb Mouse and Cap Mouse (pictured), which rely on an internal camera, orb-housed IR camera and capacitive detection, respectively. Of course, there's no word on when these might actually see the light of day"
The game they demo the second mouse with in the video appears to be cube. I suppose they used it because they had access to the source code and could modify it for multitouch interaction.
Personally, I hold the mouse with my thumb and ring-finger on the sides with my index and middle fingers resting on the buttons. When I'm at home using my Microsoft Intellimouse Optical (not explorer), I use the same grip except that I use the top joint of my thumb to hold the mouse so I twitch the tip of my thumb to hit button 4.

I move the mouse with a combination of movements including the use of my ring-finger (holding onto the mouse), my thumb (holding onto the mouse), and, to a lesser extent, my wrist which rests on a gel pad.
Why? Because my fingers are much more dexterous than my wrist and thus it's better for moving around multiple links, playing an FPS, or doing any kind of visual editing.
And yet... they seem to think I want a touchpad on a bump.
An ergonomist taught me that one thing you do not want to do is continually hold your button clicking fingers away from the buttons. That kind of static loading on the extensor muscles is really bad. While using a mouse and are not actively clicking, you want the fingers to rest on the buttons without extensor or flexor muscles being used (preferably with an armrest supporting your entire forearm). With these touch sensitive devices you HAVE to use the extensor muscles to keep the fingers away from the device.
