    Abstract: A pressure detection device of detecting a forced state of a deformable object includes a body, an image sensor and a processor. The body is a deformable hollow structure. The body has an inner surface and an outer surface, and an identifiable vision feature is disposed on the inner surface. The image sensor is disposed inside the body and faces the inner surface of the body, and is adapted to capture a frame containing the identifiable vision feature on the inner surface. The processor is electrically connected with the image sensor, and adapted to analyze position variation of the identifiable vision feature within the captured frame for identifying a motion type of a gesture applied to the outer surface of the body.

    Abstract: An auto clean machine comprising: a chassis; an internal light source, located inside the chassis, for emitting internal light; an external light source, located outside the chassis, for emitting external light; an optical sensor, configured to sense optical data generated according to the external light or according to the internal light; and a control circuit, configured to analyze optical information of the optical data. If the internal light source is activated, the external light source is de-activated and the control circuit determines variation of the optical information is larger than a variation threshold, the control circuit changes the internal light source to be non-activated and the external light source to be activated.

    Abstract: An optical sensing module including a lens and a sensing device is provided. The lens has an optical axis. The sensing device is disposed under the lens, wherein the sensing device is to receive an object beam passing the lens. The optical axis of the lens deviates from a geometric center of the sensing device. An optical sensing module including a prism film, a sensing device and a lens is further provided. The prism film has a plurality of prisms. The sensing device is disposed under the prism film, wherein the sensing device is to receive an object beam sequentially passing the prism film and the lens. The lens is disposed between the prism film and the sensing device.

    Abstract: An image identification method is used to eliminate accumulated error of operation of a joystick. The joystick has an optical sensor adapted to analyze a movement of a plurality of identification dots disposed on a stick body. The image identification method includes receiving a series of detection images, setting a first identification dot of the plurality of identification dots as being a reference identification dot, and setting a second identification dot of the plurality of identification dos as being the reference identification dot and cancelling the first identification dot as being the reference identification dot when the first identification dot is near a border of the detection image. A position change of the reference identification dot in the series of detection images is used for identifying a control status of the joystick.
