Measuring walking speed/intensity?

-

hey guys,

i'm working on project similar this:

http://www.youtube.com/watch?v=vxb0uupgt2q&feature=player_embedded

i looking way measure intensity or speed of someones walk , data determine led light output.  would accelerometer work this?  how measure walking speed?

thanks!
matt

i think accelerometer work. on every step should see increase in magnitude of acceleration vector (or @ least sizeable change). time between these pulses indicate walking speed. you'll have calibrate how long each step is.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
