joystick text entry with word prediction for people with motor impairments
Joysticks are used by people with motor impairments as an assistive device which acts as a replacement for the keyboard and mouse. Most existing entry methods that use the joystick take the form of on-screen or selection keyboards which require multiple movements of a joystick to enter a single character, making text input slow. We try to reduce the number of required joystick movements by adding word completion and next word prediction. Evaluations show text entry with word prediction is 30\% faster compared with entry on a regular selection keyboard and reduces the amount of movements by 50\%, even for first-time users with less than 15 minutes of practice.
