Accessible Remote Controls for Older Adults with Mildly Impaired Vision

Abstract

A three-phase methodology was used to design an accessible photo CD player for older adults with mildly impaired vision. During Phase I of the study, critical barriers to a photo CD player were identified that prevent older users with presbyopia from operating this product. These barriers included small Remote Control Unit (RCU) labeling, low label-background contrast, and inadequate feedback from the player system. During Phase II, cost-effective solutions were identified through research into existing literature and available technologies. Phase III evaluated the efficacy of these design modifications on both the accessibility and usability of the photo CD player. The results of the Phase III empirical study indicated that enlarging a RCU and using high contrast labeling significantly improved accessibility. Overall, these results support the use of such a three-phase methodology to design accessible consumer products for users with special needs.
