Control of Simulated Arm with the Vocal Joystick

The Vocal Joystick: Evaluation of Voiced-based Cursor Control Techniques

Mouse control has become a crucial aspect of many modern day computer interactions. This poses a challenge for individuals with motor impairments or those whose use of hands are restricted due to situational constraints. We present a system called the Vocal Joystick which allows the user to continuously control the mouse cursor by varying vocal parameters such as vowel quality, loudness and pit...

Voice or Gaze? Comparative Evaluation of Vocal Joystick and Eye Tracker

In this work, we present the results of our comparative evaluation of the Vocal Joystick system and the Eye Tracker system. Vocal Joystick is a non-verbal voice-based continuous mouse cursor control system that offers an alternative method of computer interaction for people with motor impairments. Our goal was to gain an understanding for how this system compares to an existing assistive techno...

Assistive Robot Control Using the Vocal Joystick

The Vocal Joystick Demo at UIST05: A Voice-Based Human-Computer Interface

We will demonstrate a novel voice-based human-computer interface we call the Vocal Joystick (VJ), designed to enable individuals with motor impairments to use vocal parameters for both discrete and continuous control tasks. Since discrete spoken commands are not ideally suited to such tasks, our methodology exploits a large set of continuous acoustic-phonetic parameters like pitch, loudness, vo...

Control of a 2-DoF robotic arm using a P300-based brain-computer interface

In this study, a novel control algorithm, based on a P300-based brain-computer interface (BCI) is fully developed to control a 2-DoF robotic arm. Eight subjects including 5 men and 3 women perform a 2-dimensional target tracking in a simulated environment. Their EEG (Electroencephalography) signals from visual cortex are recorded and P300 components are extracted and evaluated to perform a real...
