RF-Wear system Tracks Movement for Less

Dec-18-18 The RF-Wear system relies on battery-free, passive RFID tags to offer precise skeletal tracking at an affordable rate.

Typically, depth-sensing cameras are not only expensive, they also cannot track movements out of their line of sight—and movement sensors have their own limitations. As an alternative, the team from Carnegie Mellon University created the RF-Wear system, which uses RFID tags equipped with a tiny antenna that transmits a radio single to a handheld reader device (that same device also temporarily charges the tags). Because the signal is unique to each tag, the slight differences in return time can be analyzed to determine the bend and position of the wearer’s joints.
