A recently granted patent (Publication Number: US11883102B2) discloses a vision function detection apparatus designed to assess the visual function of a test subject. The apparatus includes a display controller that presents an image for evaluation on a display screen and moves the image within the display region. A gazing point detector tracks the position of the subject's gaze on the screen, while a relation detector analyzes the relationship between the gaze's movement in different directions. A visual function detector then determines the subject's visual function based on this information, considering factors such as total distance moved in specific directions and the number of times the gaze's direction is reversed. This innovative technology offers a comprehensive and objective method for evaluating visual function in individuals.

Furthermore, the patent also describes a method for detecting vision function using similar principles. By controlling the display of an image, detecting the gazing point, analyzing the relation information of the gaze's movement, and performing visual function detection based on specific criteria, this method provides a systematic approach to assessing visual capabilities. The utilization of differences in total moved distances and the number of direction reversals in the gaze's movement allows for a detailed evaluation of the subject's visual function. Overall, this patent introduces a sophisticated apparatus and method for objectively measuring vision function, potentially offering valuable insights for various applications in the field of vision assessment and healthcare.
