Force-Feedback Slider: Multi Factor Haptic Interaction

This projects examines the use of motorized physical sliders with position and force as input and output parameters for tangible computer interaction. We have designed a device with the purpose of controlling -- in real-time -- a motor which is integrated into a slider system with accuracy and latency valuessufficient for productive interaction. This was accomplished with a microcontroller that handles the I2C protocol for communication with a master device that centralizes the sliders’information.

The system is modular, using the configuration of one mainboard and I2C protocol to communicate with the sliders. The mainboard interacts with the computer through a USB connection. The mainboard also controls the sliders, each sitting on a slider board.
