Abstract: In an example, distance determination can utilize an electronic device including an infrared sensor to detect a thermal signature of a subject at a first location and a thermal signature of the subject at a second location, a distance sensor to determine a distance of the subject at the first location from the electronic device, and a controller to determine a physical size based on the determined distance and the thermal signature of the subject at the first location, and determine a distance of the subject at a second location based on the physical size and a thermal signature of the subject at the second location.
