Is a big button interfaceenough for elderly users? : Towards user interface guidelines for elderly users

Abstract

In the world today, the portion of aging people grows continuously. Due to successfulof healthcare services, people are living longer and the number of newborn isdecreasing. This can imply that the population of young and working people isdecreasing in many countries. This leads to the mean value incrementing of the meanworld population’s age value in the whole world. It has become more and moreimportant to consideration human factors of elderly people in many businesses.Software companies have to consider design of software concerning of usability forageing people. Currently, most of the software is designed to support younger users.To support elderly users, we have to consider more on age-related differences. Thisthesis presents a literature survey, and related theories used in designing graphic userinterface for ageing people. Besides, criteria for designing software for older users arealso discussed and suggested as guidelines for future studies and development. Thepurpose is to improve older users’ potential in using information technologies, and topotentially allow older users to gain more benefit from using of computer software.A case study for software design for elderly users was implemented to verifysuggested guideline and gain deeper design understanding. The elderly volunteerswere involved in design evaluation process. The results from case study have showneffectiveness of the design guideline approach.
