METHOD OF DEVICE FOR DETECTING A TOUCH BETWEEN A FIRST OBJECT AND A SECOND OBJECT

摘要

The 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.

1. A method of 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, comprising the steps of:
providing at least one thermal image of a portion of the second object; determining at least two temperature differences between temperatures measured at different positions in the at least one thermal image or at least two derivatives of temperature in the at least one thermal image; 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, wherein determining the pattern comprises determining one or more differences between the at least two temperature differences or between the at least two derivatives; 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.
