Observations from a case study on user adaptive reminders for medication adherence

We present the design and exploratory evaluation of a sensor-driven adaptive reminder system for home medical tasks. Our prototype implementation consists of a mobile reminder delivery device and ambient sensors for determining opportune moments for reminder delivery. A volunteer used the prototype in a residential research facility while adhering to a regimen of simulated medical tasks for ten days. Based on this case study, including direct observation of individual alert-action sequences, we make four recommendations for designers of context-sensitive adaptive reminder systems.
