Abstract
Inverted glasses are used to see flip vertical view or flip horizontal view. Namely, our field image can be rotated by 180 degrees with this device. Inverted glasses are composed of triangular prisms, which enable to locate the field image by total reflection. In recent years, it used to investigate the sensory adaptation. Researches concerned psychology and brain science using it has been actively. Most of researches in these fields were made for working and adaptability of the brain. However, the researches about the movement of the line of sight have not been investigated so far. In this laboratory, we have developed a system for detecting line of sight. Therefore, in this research, for the first time, we developed inverted glasses that are equipped with transparent optical sensors, as shown in Fig. 2. Using this device, we measure the movement of the line of sight when the field image is rotated by 180 degrees.
