Abstract | |||||||||||||||
| The Vocal Joystick is a novel human-computer interface mechanism designed to enable individuals with motor impairments to make use of vocal parameters to control objects on a computer screen (buttons, sliders, etc.) and ultimately electro-mechanical instruments (e.g., robotic arms, wireless home automation devices). We have developed a working prototype of our “VJ-engine ” with which individuals can now control computer mouse movement with their voice. The core engine is currently optimized according to a number of criterion. In this paper, we describe the engine system design, engine optimization, and user-interface improvements, and outline some of the signal processing and pattern recognition modules that were successful. Lastly, we present new results comparing the vocal joystick with a state-of-the-art eye tracking pointing device, and show that not only is the Vocal Joystick already competitive, for some tasks it appears to be an improvement. 1. | |||||||||||||||
