Pretend like you are using a real mouse,
and a camera interprets your hand
movements and finger gestures. An index
finger tap would be a left click, middle
finger tap a middle click, ring finger tap a
right click, middle finger drag a scroll.
There are several vantage points where the
may be situated. It could be a
stationary position near the surface, a
birds eye view from the top of a monitor,
or a close-up view from the bottom of the
user's palm. The best camera position
should be determined by experiments.
The benefit of this device is that it's more
portable than a traditional mouse.

||Sounds expensive, but good. Welcome to the HB. Though they do have these that track your eye movements and use blinks as clicks.
||I think rhatta may have been around longer than you DF. strange times!
||well my account got lost with the crash
so I look new :)
||d'oh! the link i just added points to a
||"using a real mouse" - one that wriggles and runs about eating crumbs...?
||But whatever technology you use, I want a something that is tied to what I am clicking on - no more abstract wave your hands about over here to do something over there.
||Products like these have been in use for years. We use one system for CAD design, where 2 cameras capture 3D information (e.g., position of your hand). Some cheap similar products exist - like a projection keyboard - where the entire keyboard is projected onto any surface, and sensors detect your fingers doing key taps.
||It sounds like you could use a "bluescreen" app with a webcam or 2 pointed at your monitor, or a piece of posterboard with target locations on it. Should give a very "natural" feeling interface.
