The PRISM lab investigates intelligent system technologies and analytical methods, and their exploitation in understanding the physiological underpinnings of functional rehabilitation in children.  In so doing, we seek ecologically relevant, innovative assistive technology solutions to enable children with disabilities to achieve their personal best and with their families, more fully participate in life activities.


Access innovations for children and youth with severe disabilities.  Developing novel access technologies to enable communication, computer use, environmental control, and creative expression (e.g., music, painting) with brain-machine interfaces (optical, ultrasonic, electrical), facial thermography, mechanomyography, otoacoustic emissions, peripheral autonomic signals, vocal fold vibrations, extant vocalizations and computer vision-based access. (in collaboration with the Toronto District School Board).

Kinetics of handwriting and drawing. To better understanding the biomechanics of fine motor difficulties, we have been studying the kinetic profiles of writing and drawing in various populations using uniquely developed grip-enabled writing implements.

Automatic classification of swallowing safety. We have developed accelerometric measurements of swallowing in child and adult populations, as well as associated signal processing and pattern classification algorithms.

Neuromotor dynamics of quasi-periodic movement.  Statistical persistence of extended walking and drawing activities under various conditions (e.g., aural/visual metronomic pacing, compliant surfaces, treadmill, overground) with the goal of elucidating the functional purpose (e.g., metabolic efficiency and dynamic stability) of such dynamics.
