## Title
Electronic eyeglasses

## Abstract

An electronic eyeglasses includes a camera module and a controller. The camera module captures consecutive images of eyes wearing the electronic eyeglasses. The controller includes a recognition module, a storage module, and a control module. The recognition module recognizes movement of the eyes by processing the consecutive images. The storage module stores an index table having a collection of eye movements and a collection of commands each of which is associated with one of the eye movements. The control module indexes a command from the index table using the movement of the eyes and controls the electronic eyeglasses to execute the command.

## Background
BACKGROUND
1. Technical Field
The present disclosure relates to eyeglasses and, particularly, to an electronic eyeglass.
2. Description of Related Art
Electronic eyeglasses are eyeglasses integrated with micro-projectors, camera modules, touch panels, microphones, speakers, and various sensors to capture and display information. Currently, electronic eyeglasses can be operated by voice control. However, it may be problematic for users who have difficulty speaking or inappropriate when operating in some locations such as libraries or classrooms.
Therefore, it is desirable to provide electronic eyeglasses, which can overcome the above-mentioned problems.

DETAILED DESCRIPTION
Embodiments of the present disclosure will be described with reference to the drawings.
Referring to FIGS. 1-2, an embodiment of electronic eyeglasses 10 includes a frame 110, a display device 120, an infrared light source 130, an infrared camera module 140, and a controller 150.
The frame 110 includes a main body 114 and a pair of legs 112 extend from opposite ends of the main body 114. The legs 112 can be made of aluminum and are integrated with control circuits 102, a control panel 104, a microphone 106, a speaker 108, various sensors 10a, and a battery 10b, which can be connected with each other. The control circuits 102 are configured for controlling and coordinating the electronic eyeglasses 10. The control panel 104 is configured for receiving user touches. The microphone 106 is configured for receiving voice inputs. The speaker 108 is configured for outputting sound. The various sensors 10a can be gyroscopes, global positioning system sensors, and so on. The battery 10b is configured for supplying electric power for the electronic eyeglass 20.
The display device 120 is configured for displaying information for eyes 20 wearing the electronic eyeglasses 10. In this embodiment, the display device 120 is a micro laser projector directly projecting the information onto the eyes 20. However, referring to FIG. 3, in another embodiment, the electronic eyeglasses 10 includes a pair of glasses 160 framed by the main body 114. The display device 120 is a transmissive-type liquid crystal display formed on the glasses 160.
The infrared light source 130, such as an infrared light emitting diode, is configured for emitting infrared light to the eyes 20.
The infrared camera module 140, such as a common camera module having an infrared band-pass filter 142, is configured for capturing consecutive infrared images of the eyes 20.
By employing the infrared light source 130 and the infrared camera module 140, the eyes 20 can be clearly imaged even in dark. In addition, the infrared light does not interfere viewing of the display device 120. However, in other embodiments, the infrared camera module 140 can be replaced with a common camera module to capture consecutive images of the eyes 20 and the infrared light source 130 can be omitted.
The display device 120, the infrared light source 130, and the infrared camera module 140 are positioned on the main body 114 and aimed at the eyes 20.
The controller 150 can also be integrated on the legs 112 and includes a recognition module 152, a storage module 154, and a control module 156.
The recognition module 152 is connected to the infrared camera module 140 and configured for processing the consecutive infrared images, recognizing the pupils 22 of the eyes 20, and thus recognizing movement of the eyes 20.
The storage module 154 stores an index table having a collection of eye movements and a collection of commands each of which is associated with one of the eye movements. The control module 156 is connected to the recognition module 152, the storage module 154, and the display device 120, and is configured for indexing a command from the index table using the movement of the eyes 20 and the index table and controlling the display device 120 based upon the command. In detail, the control module 156 compares the movement of the eyes 20 with each of the eye movements in the index table and finds the command associated with one of the eye movements that is substantially identical to the movement of the eyes 20.
In this manner, as an example, the control module 156 can interpret a trajectory of the pupils 22 (i.e., the movement of the eyes 20) as a trajectory of a cursor 122 (see FIG. 3) on the display device 120 (i.e., the command to control the cursor 122 to move along the trajectory), which is identical to the trajectory of the pupils 22, and the control module 156 can also interpret winking of the eyes (i.e., the movement of the eyes 20) as clicking of the cursor 122 (i.e., the command to control the cursor 122 to click)
In other embodiments, the commands can be used to control the electronic eyeglasses 10 in addition to controlling the display device 120.
As such, the electronic eyeglasses 20 can be operated by eye movements.
The electronic eyeglasses 10 can further includes a switch 170 configured for activating or inactivating control of the eye movement. The switch 170 can be a button on the control panel 104.
The electronic eyeglasses 10 can further includes a pair of contact lenses 180. Each contact lens 180 includes a central infrared reflective region 182 to increase reflectivity of the infrared light when the contact lenses 180 are worn by a viewer.
It will be understood that the above particular embodiments are shown and described by way of illustration only. The principles and the features of the present disclosure may be employed in various and numerous embodiment thereof without departing from the scope of the disclosure as claimed. The above-described embodiments illustrate the possible scope of the disclosure but do not restrict the scope of the disclosure.
