Gaze-triggered selective information display

We propose a 2 dimensional information display triggered by the eye movement of the viewer. This display is composed of two units, a rapid frame rate camera and a single LED (Light Emitting Diode) array. The camera captures images around the viewer's eyeball. When the display detects the viewer's rapid eye movement known as a saccade, the LED array flickers synchronized with the saccade. Through the retinal afterimages drawn by the saccade, the viewer can perceive 2D images with only a single light array. If we can detect the viewer's saccade as it occurs in real-time we can successfully show 2D images by flickering the light sources within its interval. Additionally, if we can detect when and who makes saccades, the gaze-triggered display can present different 2D images to each person using only one light array. Considering these characteristics, gaze-triggered display can be a new type of augmented reality visual display.
