Summary –
DazzleVR is a VR system designed to induce the sensation of dazzle (intense brightness) by combining visual and tactile cues. It utilizes afterimages by rendering supplemental residual images at the user’s gaze point and implements a pseudo dazzle reflex by temporarily darkening the display (simulating eye closure) and applying subtle vibration to the eyelid area. Together, these mechanisms aim to evoke an authentic dazzling experience in VR without needing excessively bright displays. Users feel both a lingering brightness and a reflexive “blink-like” effect, enhancing immersion and perceived realism
Image Description
The visual shows a VR scene with a strong light source (e.g. a spotlight or flare), while a faint complementary afterimage overlays the user’s gaze direction. The vignette may include labels such as “DazzleVR” or “Afterimage + Reflex,” reinforcing that it’s a perceptual interaction demo.
