Does by putting the green/red filter infront of wiimote to make calibration better does that mean general mouse tracking is better too?Some pictures of the film you are using would be good, I assuem just a filter (like they use infront of Theatre lighting to make various colours, just maybe a bit thinner).
I tried the laser pen and it worked very smoothly if the wiimote is one meter away from the wall. If further, still I could calibrate, but lines are not very controllable.
1.Do you think it is a power output problem or an IR laser would be better?2. what is the longest distance (between the laser dot and the wiimote) you experienced?
