Healthcare TV-Based User Interfaces for Older Adults


Designing for older adults is different from designing for younger adults. Older adults are usually less enamored with technology than they are about getting things done and usually experience a range of perception and cognition issues.

This study documents the analysis, design and evaluation of a TV system for the European project eCAALYX – Enhanced Complete Ambient Assisted Living Experiment – targeted at older adults suffering from a selection of chronic conditions. User-Centered Design methodology was used to concentrate on older adults’ specificities and therefore create an adequate product that is easy to use by them. In this context, we applied user research, personas, low-fidelity prototyping and user based evaluation. User Research was used to understand the target audience of the project. Personas were created to concentrate on the goals of the different types of users of the system. Finally, a low-fidelity prototype of the Health Channel was created and iterated a number of times with feedback from user based evaluation.

Based on the knowledge derived from the process described before, guidelines were created to drive the design of user interfaces for the TV targeted at older adults. These guidelines include aspects related to the design of the user interface but also to the preparation of usability tests.
