Hey! I'm working on a project where I want to basically control the rotation of a sphere using my hand. Sort of like Minority Report meets Google Earth. However the project is turning out to be seem more complicated than I originally thought so I wanted to see what help I could get.
Originally I was thinking of using the ez430 Chronos Wristwatch from TI and using its accelerometer to control my sphere. But the more I got into that idea the more I realized how hard this must be.
I thought I could track a hand's position just by using an accelerometer but I've heard that in order to get actual position data you have to take a double integral of the accelerometer data which causes errors (drift) to come up exponentially over time.
Then I read about using an IMU which pairs a gyro with an accelerometer to get more accurate readings, but is that overkill?
Essentially I'd like to create the illusion for a user that when they move their hand around a spherical model would spin around, like a virtual 'globe' that you can physically manipulate to see different sides of. Does anyone have some good ideas for an electronics interface that can help me do this?
