This paper aims to improve user interaction by establishing a SmartDisability Framework for the healthcare and assistive technology industries through considering mappings between Disability Types, Range of Movement (ROM) and Interaction Mediums to produce Technology and Task recommendations. The SmartDisability conceptual model (based on the familiar disability symbol) is the result of the Framework being populated through a systematic literature review of disability classification, ROM, interaction mediums, ‘off-the-shelf’ technologies and tasks. A previously conducted requirements elicitation process, involving surveys and semi-structured interviews, and a described usability evaluation involving touch and head-based interaction methods augmented the framework. The evaluation was conducted using a simulation of SmartATRS; a smartphone system that controls Automated Transport and Retrieval System (ATRS) enabling a user with disability to autonomously dock a powered wheelchair (powerchair) onto a platform lift of a vehicle, as well as controlling an automated tailgate and a motorised driver’s seat. System Usability Scale (SUS) and NASA Task Load Index (NASA TLX) was applied to measure the usability of each interaction method. Discussions of future work are provided including the anticipated framework validation process that will utilise focus groups considering fictional personas. The SmartDisability Framework will be exploited through the development of a smartphone or web-based application.
