[gui-talk] IPhone braille input

[Lloyd Rasmussen]

You are talking about accelerometer chips.  Their early mass-production use 
was for air bags for cars.  They can be built to sense acceleration in 1, 2 
or 3 dimensions.  They are part of a class of devices called 
micro-electromechanical systems or MEMS.

Apparently the iPhone 3GS has a compass built into it also.
