Best-in-class technology

  • Reliable eye tracking across the population regardless of eye color or shape

  • Slippage compensation and persistent calibration for consistently strong data

  • Patented 3D eye model and two cameras per eye ensures accurate gaze data

  • Accelerometer, gyroscope, and magnetometer differentiate head and eye movements

  • The scene camera's increased field of view in Tobii Pro Glasses 3 makes a major difference when conducting wayfinding research, especially in an outdoor environment where, with a narrower field of view, we would lose track of the gaze data. The design of Pro Glasses 3 is very comfortable, making them unobtrusive to wear which is an important factor to collect unbiased insights.
