Abstract

Abstract:
This paper presents a method of computer interaction using the IS-300Pro Precision
Motion Tracker. The motion tracker compares the gestures with a defined pattern of
movement so that it can be recognized. The method is developed using infrared light
emitting diodes (IR LEDs) attached to the thumb and index fingers of two gloves, and
the IS-300Pro motion tracker connected to a computer using the USB port. A
microcontroller unit (MCU) supporting USB connection is employed for computer
interface. Software developed specifically for the application is installed in the
computer. The system is able to recognize gestures for alphanumeric characters, as well
as user-defined gestures. The software interprets the gestures captured by the motion
tracker and translates them to corresponding response hardcoded in the software. Three
software programs were developed to demonstrate the capabilities of the system.
Experiments show that distance between the sensor and IR LEDs affects the accuracy of
gesture recognition and interpretation.
