| Outline of Final Research Achievements |
The purpose of this study is to obtain the useful suggestions for the development of a near-infrared LED light source for detecting the feature points (pupils and corneal reflections) for gaze detection especially under intense illumination environment. At first, we tried to develop a light source which irradiates two wavelength lights from the inside of an aperture of a camera by using small mirrors or a half mirror. However, the feature points were not always detected. Therefore, a new light source consisting of small mirror-type LEDs that were arranged in fourfold concentric rings was proposed. Under the dark condition, the second inner ring was lit. Under the intense illumination condition, the first inner ring was lit as well as the second inner ring because of a lack of light power. This results show that the feature points can be detected correctly both under the dark and intense illumination conditions.
