accelerometer base mouse

We tried ATMEGA 16 & CYWM 6935 wireless accelerometer based mouse but we failed to get actual position based mouse with double integration of acceleration profile...

so we finally ended up with tilt based mouse...posted at with source code

Has anyone tried position based approach...?

 

use accelerometer as mouse linux driver

Hi

Its kind of funny how similar ideas we come up with.. When ADI came up with their mems accelerometers, I had plenty of ideas on mind. This was one I actually tried, I made project of it for my linux driver course with my friend at our university...

Anyway We tried location approach, that didn't work great. We ended up using it just by tilting it. I think the problem was 2 axis accelerometer, its impossible to distinguish between tilt and actual location movement. You might have better change with 3 axis device and trying to figure out the position with earths constant 1g down. Together with a gyroscope it would work for sure, but those are too expensive for commercial mouse type products..

just my two cents. Have fun with accelerometers, those are great toys to play with

Re: use accelerometer as mouse linux driver


I am working on the position sensing algorithm base mouse and I have acheived certain amount of success using double integration. Once the project is complete I will make the source code open to everybody.
