Peer-reviewed paper: Investigating the gravity well algorithm to help in pointing in electronic interfaces by motor-impaired users.

Purpose - The purpose of this paper is to design an adaptation algorithm to facilitate pointing in electronic interfaces by users with motor impairment.Design/methodology/approach - First, the algorithm was optimized using a simulator, then the algorithm was validated through a user study involving seven motor-impaired and six able-bodied users and three different pointing devices.Findings - The algorithm significantly reduces pointing time overall and most participants pointed quicker with the gravity well than without it.Originality/value - The adaptation algorithm can significantly reduce pointing time for both motor and situational impairment.
