Visual function detection apparatus for determining trackability of line of sight
A recently granted patent (Publication Number: US11957411B2) discloses a visual function detection apparatus designed to assess the trackability of a test subject's line of sight. The apparatus includes a display controller, a gazing point detector, a positional relation detector, and a visual function detector. The display controller displays an image on a screen, while the gazing point detector tracks the subject's eye movement. The positional relation detector measures the distance between the gazing point and the image, and the visual function detector determines the trackability based on this distance. The apparatus can adjust the speed and position of the image to evaluate the subject's line of sight accurately.
Furthermore, the patent describes a method for detecting visual function using the apparatus and a computer-readable storage medium storing a program to execute the method. The method involves displaying an image, detecting the gazing point, measuring the distance between the gazing point and the image, and determining the trackability of the line of sight. By continuously adjusting the position and speed of the image, the method can provide a comprehensive assessment of the subject's visual function. Additionally, the patent includes provisions for displaying images with varying contrasts and adjusting the moving speed based on the subject's trackability criteria, enhancing the accuracy of the assessment process. Overall, the patent introduces a sophisticated system for evaluating visual function that can be beneficial in various medical and research applications.
