drawing with lights

Projects General Guidance

hi everyone!
i really need suggestions on this project...
i have a sphere that lights up whenever someone take it, the first color of the sphere is based on the hand temperature of the user that take the ball
after that with a accelerometer and a gyroscope you can choose to change the color of the sphere by rotating it or by shaking it
well, this is the easy part i guess...
now come the real deal...
i want to make this "ball" a "drawing instrument", what i mean?
whenever the user moves the sphere i want to recreate that movement on a wall (using a projector)
and i want to give to the line drawn the color that the sphere has in that moment (so you will have a line with multiple color shades based on your interaction with the ball)

is it possible to do such a thing?
is it possible to add more spheres and have the same features? (like three of them in the same room)

i really don't know how i could do the tracking of those balls...

on some topics i found that accelerometer and gyroscope could be enough, somewhere else that it's not possible and a real mess
other ideas?

Wow, such a ball would be fun to play with!

I think you may have to use something like a kinect sensor, or some indoor GPS system which would be expensive and difficult to operate with.

Anyways, Im just suggesting what came to my mind, good luck! :slight_smile:

I have seen this advertised.

Movement tracking is the most important part of your project, and it's not easy to achieve. Start with only a gyro/accel sensor, and try to track its position. If it works, mount it into the ball and test again.
