In one solution, Apple would require the user to wear a touch-sensitive device on their fingers. In another solution, the glasses would use a camera to track a person’s fingers as they move. To determine whether a virtual button has been pressed, the technology could use heat to monitor temperature changes in the object that is being pushed. The longer a press, the warmer the object will become.

AbstractThe present disclosure is related to a method and device for detecting a touch between at least part of a first object and at least part of a second object, wherein the at least part of the first object has a different temperature than the at least part of the second object. The method includes providing at least one thermal image of a portion of the second object, determining in at least part of the at least one thermal image a pattern which is indicative of a particular value or range of temperature or a particular value or range of temperature change, and using the determined pattern for detecting a touch between the at least part of the first object and the at least part of the second object.
