Abstract
This paper examines and compares the usability problems associated with eye-based and head-based assistive technology pointing devices when used for direct manipulation on a standard graphical user interface. It discusses and examines the pros and cons of eye-based pointing in comparison to the established assistive technology technique of head-based pointing and illustrates the usability factors responsible for the apparent low usage or ‘unpopularity’ of eye-based pointing. It shows that user experience and target size on the interface are the predominant factors affecting eye-based pointing and suggests that these could be overcome to enable eye-based pointing to be a viable and available direct manipulation interaction technique for the motor-disabled community.
