Pseudo-Attraction Force

A haptic illusion technique that creates the sensation of being pulled or pushed in a specific direction by exploiting the nonlinear relationship between physical and perceived acceleration. The technique uses asymmetric oscillation: a strong, brief acceleration in the intended direction followed by a weaker, slower return motion. Because human kinesthetic perception cannot detect the gentle return acceleration, the brain interprets the motion as a sustained unidirectional pull. This perceptual trick enables compact handheld devices to generate intuitive directional cues for navigation without requiring external force anchoring, making it particularly useful for guiding visually impaired pedestrians.
