Abstract: 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.

Abstract: There is provided an optical navigation device including an image sensor, a processing unit, a storage unit and an output unit. The image sensor is configured to successively capture images. The processing unit is configured to calculate a current displacement according to the images and to compare the current displacement or an accumulated displacement with a threshold so as to determine an outputted displacement. The storage unit is configured to save the accumulated displacement. The output unit is configured to output the outputted displacement with a report rate.

Abstract: A method of identifying iris is provided. The method includes providing a plurality of incident lights entering an eye located at a reference position; setting a first, second and third reference points; forming a first, second and third measuring glint by the incident lights after the eye moves to a measuring position; capturing an eye image of the eye including a first, second and third measuring glint images and an iris image; analyzing a gray scale value of the eye image to obtain the positions of the first, second and third measuring glints; and calculating a variation of the distance between the first measuring glint and the second measuring glint, a variation of the distance between the second measuring glint and the third measuring glint to obtain an resolution variation of the iris image when the eye is located at the measuring position.

Abstract: An eye detecting device includes an optical assembly, an image sensor and an arithmetic unit. The optical assembly provides a plurality of incident lights. The incident lights enter into eyes to form a plurality of glints. At least part of glints is near a pupil of the eye. The image sensor is used to capture an eye image. The eye image includes images of the glints. The arithmetic unit analyzes the gray scale value of eye image and obtains the distributions of the glints through the gray scale value. The arithmetic unit determines the position of the pupil of eye according to the distributions of the glints.
