Touch screen user interfaces for older adults: button size and spacing

Published: 22 July 2007 Publication History

Abstract

This study investigated the optimal button size and spacing for touch screen user interfaces intended for use by older adults. Current recommendations in the literature are aimed at general audiences and fail to consider the specific needs of older adults. Three independent variables, button size, button spacing, and manual dexterity were studied in two experiments that measured reaction time, accuracy and user preferences. Design recommendations for touch screen button size and spacing for older adults are stated based on these experiments. The paper also discusses the role of manual dexterity in designing appropriate touch screen interfaces for older adults.
