Gesture controlled user interface for elderly people
MetadataShow full item record
Global population aging has become a serious issue, which gains increasing attentions all over the world. More and more researches about elderly people were conducted, especially about senior´s interaction with computer. Hence, the goal of this research is to identify usability and accessibility issues faced by elderly people and provide a usable and accessible gesture controlled user interface (GCUI) for them. Moreover, this thesis provided some suggestion of accessibility guidelines for GCUI. Meanwhile, the problem of aging is particularly significant in China, which is one of the world´s most populous countries. Considering this problem, this study was performed over Chinese elderly participants. Due to the wide gap between younger designer´s experience and experiences of the older users, it is important for designers and developers to increase the awareness of the characteristics of elderly people. Hence, the user-center design approach was used in the process of design and development. User testing, interview and accessibility testing were used to identify the usability and accessibility of prototype of GCUI in different stages. The result of usability testing confirmed that the prototype of GCUI is easy for elderly people to learn and understand. Furthermore, the result of accessibility testing indicated that this prototype of GCUI partially meet the accessible requirement. However, there are some limitations in this thesis. For instance, user experience is dependent on the accuracy of hand gesture detection and recognition. The program lacks audio feedback and does not support assistive technology. All in all, GCUI can provide a new opportunity for elderly people to interact with computer.
