In today’s release of the GM version of IOS 14.2, apple added a very interesting auxiliary function: the magnifying glass application can detect the distance between people, so that blind users can effectively keep distance with others. The function is developed based on Apple’s arkit. The barrier free team realizes that lidar system of iPhone 12 pro and pro Max can provide accurate distance measurement, which is a very useful tool for users with visual impairment. < / P > < p > during the outbreak, the distance between people recommended by the government should be kept above 6 feet. But it is difficult to determine the distance more intuitively. This new feature will be part of the magnifying glass application, which uses lidar and wide-angle cameras from pro and pro Max to provide feedback to users in various ways. < / P > < p > first, the magnifying glass application will detect the presence of people around. If someone is detected, the distance to him is measured and updated regularly as they approach or move further away. Sound corresponds in stereo to the direction of the person in the camera view. < / P > < p > Second, it allows users to set audio reminders corresponding to certain distances. For example, if they set the distance to 6 feet, if a person is more than 6 feet away, they will hear one sound, and if they are within that range, they will hear another sound. < / P > < p > the third function may be particularly useful for people with visual and auditory impairments. It is a tactile pulse, which is faster as people approach. Finally, there’s a visual feature for people who need some help identifying their surroundings, and the arrow points to the person detected on the screen. < / P > < p > the system requires a good image on the wide-angle camera, so it cannot be used in the dark. Moreover, although the function is limited to the high-end products of the iPhone series, its practicability as a visual restoration tool is constantly improving. Global Tech
