v-HIT

Contactless Video Head Impulse Test — a mobile measurement and analysis system that replaces goggles and dedicated sensors with a phone camera and a custom stand.

A mobile measurement and analysis system that brings the Video Head Impulse Test to a contactless, portable form. Using a phone’s front camera and a custom stand at ~40 cm, it tracks head and eye movements simultaneously — eliminating the goggles and dedicated sensors of conventional vHIT hardware.

Camera frames are analysed with advanced image-processing and motion-tracking algorithms. Feature points from the face and eye region are tracked and converted to head and eye time series. The data passes through filtering, noise reduction, time synchronisation and stable-tracking stages to produce reliable measurement data.
