Abstract: A method for identifying an object, an optical sensing apparatus and a system are provided. A controller of the system drives multiple light sources of the optical sensing apparatus to emit the multiple light beams with different beam angles, controls a light sensor to sense the lights reflected by the object, and performs the method for identifying the object. In the method, the light sensor is used to sense a first light emitted by a first light source with a first beam angle reflected by the object, and sense an intensity of the reflected first light. The light sensor is also used to sense a second light emitted by a second light source with a second beam angle reflected by the object and sense another intensity of the reflected second light. Therefore, the object can be identified by integrating information of the intensities obtained by the light sensor.

Abstract: A force sensor device includes a first structure component, an optical sensor, and a flexible structure component. The optical sensor is disposed on the first structure component. The flexible structure component has a convex portion, and the flexible structure component is assembled with the first structure component to form a chamber in which the optical sensor is disposed. The optical sensor senses light ray transmitted from the flexible structure component to at least one pixel unit to generate at least one differential image and then detects a user's control force applied for the flexible structure component according to the at least one differential image. Differential image is temporal differential image, generated from successive pixel values of a single pixel unit, or is spatial differential image, generated based on temporal differential images of at least two neighboring pixel units.
