The CART Home

The technology platform used in the CART Initiative is an extension of the ORCATECH Life Lab. Developed by a team of researchers, statisticians and software developers, the platform collects data about everyday home-based activities. Data is securely sent to ORCATECH's servers, where innovative algorithms can translate it into meaningful information. The platform is designed to be:

  • Ambient: Sensors are sensitive to the presence of people and continuously collect data in real-time.
  • Technology Agnostic: The platform can accommodate new devices or new data systems, making it future-proof.
  • Unobtrusive: Sensors are discreet, blend into a home's environment and do not interfere with daily life, meaning that participant's do not need to change their daily routines.

By analyzing data that is captured by the platform, researchers may be able to observe how various activity patterns can relate to the onset of new medical problems. Learn more about the goals of CART.

Inside a CART Home

An array of sensors and smart devices are installed in a home that is enrolled in the CART study. Many of these sensors and devices originate from collaborations with CART's technology partners. Learn more about our collaborations.

Wall and Ceiling Sensors

These measure mobility by tracking walking speed, movement between rooms, and how much time is spent in a room.

Outside Door Sensors

These measure how often a participant has left their home, by tracking how often a front or patio door is opened or closed.

Digital Scale

This measures body composition, heart rate and weight.

Digital Pillbox

This measures medication adherence by tracking how often a pillbox lid is closed.

Digital Watch

This measures daily activity and sleep patterns.

Driving Sensor

This is installed in a participant's car and tracks how often a participant drives.
