ABSTRACT
We describe the Haptic Space Mouse, an input
device based on the SpaceMouse with 2 DOF translational feedback in contrast to
the rotational feedback often found in force-feedback joysticks. We use
solenoids as motors in our implementation, they facilitate frictionless
operation and add little inertia to the Spacemouse.
The force-feedback controller is an
Atmel ATmega32 microcontroller, which is programmed to decode the device
output, thus enabling us to drive the solenoids in a closed loop. A
simple host-to-device protocol is developed to specify the haptic forces.
