Comment on The Ploopy A+ Trackball Is Hereparent

Comments

A lot of people who haven't seen one are confuse it with a trackball, but SpaceMouse and its kin aren't trackballs, they're double cascaded joysticks on a fixed mount shaped like a ball.

The stump om the base works as a 2 axis tilting joystick, and the stem of the ball works like its own 2 axis XY sliding pad with extra push/pull plus twist axes. There's a wire through the stem of the knob to get the readings. Together they capture the whole 6 axis deflections for the knob.

Trackballs OTOH is just rubbing a mousepad rolled up to be a ball to operate a Magic Mouse while charging.
