Abstract

Inverting glasses invert the wearer's visual field in the vertical or horizontal direction using total internal reflection by triangular prisms. Inverting glasses are powerful tools for investigating neural adaptation and are widely used in the fields of psychology and brain science. However, conventional inverting glasses are not equipped with a detection system for eye movement or the line-of-sight of the wearer during experiments. Inverting glasses were developed that can be mounted with a see-through eye detection system, which consists of micropatterned dye-sensitised photovoltaic cells that determine the position of the pupil by detecting light reflected from the black and white parts of the eye. The detector does not require an external camera and is thus lightweight and has low-power consumption, which is advantageous for mounting on the inverting glasses. Using the developed inverting glasses, which swap the left and right visual fields, they conducted tracking and pointing tasks while measuring eye movement. Gaze learning curves were obtained from the experiments for the first time, which they believe will provide new and useful information to the study of neural adaptation.
