Glasses with gesture recognition function include a glasses frame and a gesture recognition system. The gesture recognition system is disposed on the glasses frame and configured to detect hand gestures in front of the glasses thereby generating a control command. The gesture recognition system transmits the control command to an electronic device to correspondingly control the electronic device.

There is provided a portable electronic device including a backlight module, an ambient light sensor, a proximity sensor and a processing unit. The backlight module illuminates with backlight brightness. The ambient light sensor is configured to detect ambient light intensity. The proximity sensor is configured to detect an object. The processing unit is configured to activate the proximity sensor when the ambient light intensity detected by the ambient light sensor is lower than a predetermined value or decreases more than a predetermined range, and to maintain or reduce the backlight brightness according to a detection result of the proximity sensor. There is further provided an automatic detection method.

There is provided a pupil tracking device including an active light source, an image sensor and a processing unit. The active light source emits light toward an eyeball alternatively in a first brightness value and a second brightness value. The image sensor captures a first brightness image corresponding to the first brightness value and a second brightness image corresponding to the second brightness value. The processing unit identifies a brightest region at corresponding positions of the first brightness image and the second brightness image as an active light image.

An operation method of an optical touch device includes: emitting, by a light emitting unit, a light beam to illuminate an object; capturing, by an image sensing device, an image of the object reflecting the light beam; selecting all pixels in the image having a brightness greater than or equal to a brightness threshold; sorting the selected pixels along a first coordinate axis of the image, a second coordinate axis of the image or based a pixel brightness; selecting the top first predetermined ratio of pixels from the sorted pixels as an object image of the object; and calculating a gravity center of the object image according to positions of the top first predetermined ratio of pixels or according to the positions of the top first predetermined ratio of pixels with a weight of pixel brightness. An optical touch device is also provided.
