Good human computer interface design seeks to ensure that Fitts’s law is obeyed to allow for effective access for all. There is a lack of evidence to indicate that designing a human computer interface based on Fitts’s law is the best method to design an interface for individuals with CP. If interfaces are to be developed that allow for access by many (universally designed), we must better understand how functional levels affect the movement when accessing computers with a mouse. This research evaluates point and click tasks based on Fitts’s law to better understand differences in computer access across the MACS levels as compared to a population of typically developed peers.
Individuals with cerebral palsy use many different means to access their computers. See an an individual performing "point and click" tasks in this video.
While Dr. Almanji focused on mouse control, A. Payne is working to better understand touch screens and S. Taherian is now working with brain computer interfaces.
The brain computer interfacing has attracted attention from the media.
