INTERACT offers a comprehensive toolkit to understand impacts of urban form changes on health. Here are a few of our tools.

INTERACT Online Questionnaires

Mobile Sensing Tools

Ethica Data

Ethica is a free smartphone application, which collects GPS and accelerometry data. These data allow us to measure location-based physical activity, infer transportation mode and measure well-being using ecological momentary assessment.


The SenseDoc is a research grade multisensor device used for mobility (GPS) and physical activity (accelerometer) tracking. These data are collected continuously and allow us to measure location-based physical activity and infer transportation mode.
