Scope
This part of IEC 63145 specifies the standard measurement conditions and measuring methods for determining specific characteristics of eyewear displays with ambient light sensors which are mainly embedded into eyewear displays (mostly the optical see-through type), including illuminance-based sensors and luminance-based sensors. The camera is included as one of the luminance-based sensors.
Purpose
Recently, the market of eyewear displays has been growing rapidly. In almost all eyewear displays, sensors are integrated to enhance immersion and interaction performance, among others. Ambient light sensors are very important for eyewear displays, especially see-through ones, adapted to applications in different environments. Therefore, there is a need to establish measurement methods for the specific functions of these eyewear displays integrated with ambient light sensors.
