Fine motion was also a concern, and we went back to our 5 bit force resolution result and thought that if you don’t have much control at slow speeds then tremor would increase inaccuracy and maybe a constant speed would be easier to stop on a dime with…. He was fascinated by this concept that an object was simple when you were not using it and complex when you were. The sensor was great in that it was sensitive and fit under a key and was easy to make- but it sucked in that it was where I learned about the problems with force-sensing resistors. He liked it- but then, a few weeks later he had a stroke. We built a gesture language into the Trackpoint that can be accessed in the firmware; the only aspect the driver exposes is Press to Magnify or Press to Select. A few pages later I read some data that showed that going to the mouse took more than. Use the id with Axis 0 and Axis 1 items.

If the notes seem sparse, that’s because the code is sparse. I put copper foil corners on the top and a foil bottom… I found that the conductive foam at Radio Shack didn’t have the hysteresis that the other chip-holding foam had.
