PSU Wear-IT

The Wear-IT application and the associated framework are designed to allow scientific, clinical, and academic researchers to design data collection protocols that minimize the amount of effort that a study requires of its participants.

Featuring real-time responsiveness and adaptive, context-dependent assessments and interventions, Wear-IT uses passive data collection approaches in combination with active, low-burden surveys to balance participant effort and hassle against the quality of the data available. Wear-IT can be installed on participants' own phones or shared devices, and integrates with wearable and emplaceable devices from a variety of manufacturers.

Wear-IT is designed with participant privacy and burden at the forefront, and is built to open new opportunities to understand and improve people's day-to-day lives. Wear-IT’s demo does not collect data and is available to anyone. To collect real scientific data involving human subjects, ethical oversight from an accredited institutional review board is required, including comprehensive informed consent.

Features:

-Surveys are managed on a web server and deployed to the phone.
-Surveys can be triggered by Location, Schedule, User, with more triggers on the way!

-Includes Scheduler tool so user can select a time that is convenient for them
-Question Types:
- Informational (i.e. Display instructions)
- Time Picker
- Time Picker with Multiselect Options
- Scalable Slider with Configurable precision (i.e. Indicate how you feel on a scale of 0.00 to 10.00, OR How many servings of vegetables did you consume in half-serving increments.)
- Unit Slider (i.e. How many books did you read this summer, 0 Books to 10 Books)
- Time Scale slider (i.e. How long is your commute, 0 minutes to 2 hours?)
