Chronic diseases among elderly people have an increasing impact on healthcare systems. Telehealth interventions using smart phones and low-cost sensors have been shown to potentially increase quality of life and reduce re-hospitalization rates. While usage of internet and smart phones is generally increasing in elderly people, there is still a digital divide between younger and older users making usability a key aspect of telehealth intervention design. In this work we introduce SMILA, an interactive, voice-controlled smart mirror supporting elderly people in self-monitoring of parameters relevant to chronic heart failure. We present the design, construction, user identification using wrist-bands and linkage of the mirror to a telehealth service based on the Internet-of-Things mediation framework symbIoTe. Finally, we present initial results from a pilot study evaluating user acceptance and usability.
