The ‘MagTrack’ Translates Face Movements into Digital Instructions
Researchers at the Georgia Institute of Technology, in collaboration with ‘Brooks Rehabilitation,’ have developed the ‘MagTrack.’
The MagTrack is a pair of glasses that are capable of tracking the wearer’s facial movements from eyebrow raises to tongue movements.
The MagTrack is equipped with several inertial measurement units (IMUs) that allow it to accurately measure micromovements, such as touching your tongue to the inside of your cheek.
On top of IMUs, the MagTrack features an accelerometer, a gyroscope, and a magnetometer. The device connects to the wearer’s face through a non-toxic adhesive, preventing the device from falling off when in motion.
The researchers created the MagTrack for wheelchair users, providing a convenient way for these users to navigate the world without needing to physically row themselves.
While this is functionality that motivated the creation of the MagTrack, the applications of the device do not end here, as the team that created it has stated that they want to “push this technology and its capabilities as far as possible.”
