Is a Big Button Interface Enough for Elderly Users

In the world today, the portion of aging people gro ws continuously. Due to successful of healthcare services, people are living longer an d the number of newborn is decreasing. This can imply that the population of y ung and working people is decreasing in many countries. This leads to the mea n value incrementing of the mean world population’s age value in the whole world. It has become more and more important to consideration human factors of elderly people in many businesses. Software companies have to consider design of softw are concerning of usability for ageing people. Currently, most of the software is d e igned to support younger users. To support elderly users, we have to consider more on age-related differences. This thesis presents a literature survey, and related th ories used in designing graphic user interface for ageing people. Besides, criteria for designing software for older users are also discussed and suggested as guidelines for futu re s dies and development. The purpose is to improve older users’ potential in usi ng information technologies, and to potentially allow older users to gain more benefit from using of computer software. A case study for software design for elderly users was implemented to verify suggested guideline and gain deeper design understa nding. The elderly volunteers were involved in design evaluation process. The res ults from case study have shown effectiveness of the design guideline approach.
