idea: accelerometer daemon

I've talked with Daniel recently and told him that I was working on
recognizing contexts.
For that I'm using self-organizing maps (Nokia is using these for
gesture recognition) and I'll try to recognize walking, running,
walking up/down stairs etc.
Just wanted you to know that I'm continuing my work towards gestures,
and walking patterns for the Neo :)

This year I'm working on contexts like said before, but next year I'll
try to merge hidden Markov models and self-organizing maps for gesture
These SOM are amazing because you don't need to train them, it just
adapts using unsupervised learning.
I'm eager to see what will come out of it...
