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.
