4D-Joystick - New Possibilities for Persons with Motor Disabilities.

UNLABELLED: The 4D-Joystick is a new type of Assistive Technology which enables people with severe motor disabilities to fully control remote controlled (RC) toys i.e. MODELS: In 2013 the authors started to develop a feasibility study and built the first prototype of the 4D-Joystick which allowed to control up to 4 analogue and up to 2 digital channels. The second prototype of the 4D-Joystick allows to control up 4 analogue channels and 4 digital channels concurrently with very low latency. Furthermore the second prototype of 4D-Joystick supports functionality like Dual Rates, Expo, Invert and Dead Zone on each channel which offers additional adaptability to the users' needs. This is sufficient to control complex RC Models like airplanes, helicopters, multicopters, boats and cars. Furthermore the 4D-Joystick offers an interface to the open source software AsTeRICS. In combination with AsTeRICS the 4D-Joystick can be used as music instrument, a computer game controller and a computer input device. This paper discusses the second prototype of the 4D-Joystick and its functionality.
