To obtain more accurate quantitative results when monitoring people’s daily activities we have developed a passive data monitoring system. This Wheelchair Activity Monitoring Instrument known as the WhAMI uses odometers, tilt and seat occupancy sensors, and a Global Positioning System (GPS) to gather information about wheelchair users’ daily activities. The purpose of this pilot study was to develop and test the WhAMI. Thus far, we have completed data collection on 3 subjects. Our results demonstrate that data from the WhAMI accurately describes the subjects’ community travel, indoor mobility, and use of the tilt-in-space feature. The WhAMI is a valuable tool for collecting this quantitative data, and is designed to be used in combination with self report surveys to paint a complete picture of a subject’s activity and participation.
