Towards a platform for persuading older adults to adopt healthy behaviors

In ambient-assisted living scenarios there is the need of providing adequate support to elderly so that they can improve their quality of life. One of the most emergent needs is the capability of a system to be capable of adapting and reacting to user behavior changes. This is even more relevant when considering age related changes. In this paper, we introduce a platform supported by an End-User Development environment that allows older adults and their caregivers to tailor the context-dependent behavior of their Web applications and persuade older adults to adopt healthy behaviors. We present how this can be done by using a persuasion mechanism which collects information through sensors, identifies behavior changes and acts upon these adapting the user interface and application level. Additionally, we also show how these persuasion mechanisms can be personalized by modifying context-dependent trigger-action rules.
