WiGait is a home device that measures walking speed to identify changes in a person's body over time

Researchers from MIT‘s Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a new device that measures a person's walking speed to determine whether they are at risk from certain health issues such as cognitive decline and cardiac disease. WiGait would fit into a ‘health-aware' home of the future, as the white box can be fitted inside a room to unobtrusively keep track of movements. It resembles a blank canvas hanging on the wall.

The wireless device is able to measure the walking speed of many people at once with 95-99% accuracy. It collects anonymous data to identify changes in walking speed over time that could signal whether someone needs to adjust their health regimen. It also emits only a tiny amount of radiation, with its signals comparable to one-hundredth the amount of radiation of a cellphone.
