“An infrared touchscreen uses an array of X-Y infrared LED and photodetector pairs around the edges of the screen to detect a disruption in the pattern of LED beams. These LED beams cross each other in vertical and horizontal patterns. This helps the sensors pick up the exact location of the touch.

How do touchscreens work?

How many pixels is a finger?

An MIT Touch Lab study of Human Fingertips to investigate the Mechanics of Tactile Sense found that the average width of the index finger is 1.6 to 2 cm (16 – 20 mm) for most adults. This converts to 45 – 57 pixels, which is wider than what most mobile guidelines suggest.

Why are there minimum sizes for touch targets?

Ensure that all interactive elements are at least 1cm × 1cm (0.4in × 0.4in) in physical, rendered size and positioned with enough space from other competing touch targets to be easily and accurately acquired. Too small targets lead to longer acquisition times and errors, and are bound to cause user frustration.
