Fat Fingers, refers to the size of those sausages attached to your hands. This is pertinent when working with any touch-screen display, or dataglove based VR pointing system, as there is a need to be precise, down to the pixel. Human fingers are just too big for precision work in such areas, and frequently obscure the area being worked upon, just by their sheer size.

By using an LED array made out of cheap to buy LEDs placed in a grid with a hole in the middle for the Wii-mote to point through, some software, and some foil stickers on the fingers, a home-use, very basic multi-point interaction system is born.
The movement of the natural body when it comes to in depth, detailed tasks that require lots of little finger movements, is it seems, something which is defined as much by the tasks before and after the one the fingers are doing, as it is by the task the fingers are doing right now. This is a real problem when it comes to figuring out how to replicate natural-looking finger movements.
You are travelling through a forest, dappled sunlight streaming through the branches above, casting shadows on the ground. Leaves crunch underfoot, and the odour floats up to you. Closing your eyes, you reach out to pluck a flower - and feel nothing. Opening your eyes, you see your hand is in the middle of the plant you tried to pluck. Carefully, focussing with your eyes, by trial and error, you grasp and break off the flower, not feeling anything between your fingers. Suddenly, you realise you cannot even feel your fingers, you have not been feeling them, and you run a hand over your body, no sensation; you have to look to see you are touching skin.
AirStrike is a gesture control system designed to enable control of any pc or display interface via waving your fingers in the air, and smart sensing technology to detect those gestures accurately enough to completely replace a computer mouse or 3D pointer.
Touchscreen technology has until now, had one strong disadvantage: In inclement weather, wet, freezing cold hands result from touchscreen use, as gloves and other finger protectors have always made fingers too big and bulky to effectively use touchscreen technology, whilst masking tactile feedback with the glove?s spongy surface.
In May 2009, the Ishikawa Komuro Lab in Japan, demonstrated the capabilities that robotic manipulation of objects had reached. They had created a three-finger robot arm, with tactile sensors on its fingers, with each finger capable of independent 180 x 180 x 360 motion. All three were connected to a high-speed machine vision camera.
