Investigating the gravity well algorithm to help in pointing in electronic interfaces by motor‐impaired users

Abstract

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.
