Study assessed the efficacy of computer software that automatically adjusts various input device settings to better meet the needs of users with motor impairments. The software tested, the Input Device Assistant (IDA), recommends double click settings based on measurements of the time interval and spatial gap between clicks during a task which asks the user to double click on a series of targets. The basic principle behind each recommendation is to set double click speed and double click height and width sufficiently large to accommodate almost all user attempts at double click based on a statistical model of the measured click intervals. Study participants, 5 female and 7 male experienced computer users with motor impairments ranging in age from 26 to 71 years of age, used the IDA system to get recommendations for double click settings that matched their abilities. Participants used their preferred pointing device during the study, including a mouse, trackball, joystick, and MouseKeys. Subsequent use of the IDA settings significantly enhanced participants’ speed and accuracy when double clicking on targets with their pointing device.
