An Experiment on a High-Speed Image Projection Perceived Only During Smooth Pursuit using Striped Patterns

We have proposed a novel image display technique that uses high-speed projection to present different images depending on the user’s gaze movement direction. This method projects stripe-based frames at high refresh rates; when a user moves their gaze in a specific direction, previously hidden visual content becomes perceptible due to temporal interference patterns. In this method, the optimal gaze velocity is determined from parameters such as the decomposition parameters of the striped patterns and the projection speed of these images. However, it is known that in the human visual system, gaze velocity lags behind the target object’s velocity during pursuit eye movements. Therefore, we conducted an experiment with human subjects to compare the theoretically optimal gaze velocity with the actual measured velocity. The results suggest that the velocity of the guide point used to induce gaze movement should be set to approximately 1.5 times the theoretical optimal gaze velocity.
