Mobile Health

Our lab has been active in the mobile health research community since 2012 with the Amulet Project (of which a post-mortem summary can be found here written by Prof. David Kotz at Dartmouth). This has since turned into collaboration with Prof. Nabil Alshurafa in the Department of Preventive Medicine at Northwestern, and Prof Hester’s courtesy appointment in that department. Our goal is to reduce the effect of structural, societal, monetary, or mental barriers to receiving healthcare treatment. This has come in the form of lowering the burden of long term monitoring and interventions through novel wearable design, building tools for clinical researchers to conduct better clinical trials with strong groundtruth and high adherence, and bootstrapping clinical processes.

Early work in this space was in the design and development of the Amulet platform and software toolchain, published in SenSys’16, USENIX ATC’18, and MobiCom’19 as full papers. Amulet was the first multi-tenant and ultra low power smart watch for mobile health, allowing for a nine month battery lifetime.

Recently with Nabil Alshurafa and the HABITS Lab we have been exploring eating behaviors, and how privacy norms prevent the gathering of strong ground truth (for example with video), reducing adherence in medical trials that use wearables, as described in our IMWUT/UbiComp’19 paper. Currently we are designing new wearable devices that can non-invasively monitor eating, sleeping, smoking and mental health indicators via egocentric and low power thermal imaging and other sensing modalities.
