    Abstract: 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.

    Abstract: In one implementation, a method includes emitting light with modulating intensity from a plurality of light sources towards an eye of a user. The method includes receiving light intensity data indicative of an intensity of the plurality of glints reflected by the eye of the user in the form of a plurality of glints. The method includes determining an eye tracking characteristic of the user based on the light intensity data. In one implementation, a method includes generating, using an event camera comprising a plurality of light sensors at a plurality of respective locations, a plurality of event messages, each of the plurality of event messages being generated in response to a particular light sensor detecting a change in intensity of light and indicating a particular location of the particular light sensor. The method includes determining an eye tracking characteristic of a user based on the plurality of event messages.

    Abstract: In one implementation, a method is disclosed for providing visual coherency between virtual objects and a physical environment. The method includes obtaining, at an electronic device, first content depicting a physical surface in the physical environment using an image sensor of the electronic device. An extrinsic property exhibited by the physical surface is determined based on the first content using a visual coherency model. Second content representing a virtual object is generated based on the extrinsic property to present on a display.
