However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It doesn't happen.

(Example)

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a portable mouse using a short range wireless communication module according to a preferred embodiment of the present invention.

The portable mouse 110 includes an optical steering sensor 100, a movement determining unit 101, a key input unit 102, a control unit 103, and a near field communication unit 104. The portable mouse communicates with surrounding electronic devices 120 using near field communication.

The light steering sensor 100 includes a light source unit 100a and a light detector 100b. When the light emitted from the light source unit 100a is reflected from the surface of a human finger or an external floor, the photo detector 100b detects the light. The light detected by the photodetector 100b is converted into an electric signal in the form of current / voltage according to the intensity and output. The signal output from the light steering sensor 100 is input to the movement determining unit 101, and the distance and direction according to the movement are calculated. A digital signal processor (DSP) chip or the like may be used as the movement determiner.

The light steering sensor 100 may have a structure in which the light source unit 100a and the light detection unit 100b are separately separated, a structure manufactured by being integrated together on the same substrate, and preferably the same so as to be light and simple. It has a structure manufactured by being integrated together on a substrate. This will be described later in detail.

On the other hand, the method of sensing the movement of a human finger by the light emitted from (a) from the light source unit 100a of the light steering sensor 100, for example, a human is a light steering sensor 100, such as a touch pad of a notebook. ) Is a structure that does not hold the hand, and (b) a method of sensing the movement of the outer bottom surface by the light emitted from the light source unit (100a) is a structure in which a human holding the light steering sensor 100 directly.

According to the present embodiment, both of the above-described methods are possible, but in the case of using the high-density optical steering sensor 100, it may be advantageous to adopt the method (b). In addition, when the method of (b) is taken, for example, the light source unit 100a may be disposed in the center, and the photodetector unit 100b may be disposed in a structure that radiates in at least four directions of up, down, left, and right of the periphery thereof. At this time, the photodetector 100b may be at least four independent photodetectors 100b or integrated on the same substrate as the light source unit 100a. It can also be detected. In the latter case, such a structure can be easily realized even with a simple modification of the control unit 103. 2 is a diagram showing an example of the implementation of the light steering sensor 100 according to an embodiment of the present invention.

Referring to FIG. 2, the structure will be described in more detail. For example, if a user wants to continuously move the cursor to the right direction using a portable mouse, the user may continue to detect the light steering sensor 100. In the case of detecting light by dividing it into 4 unit photodetection areas, if the user wants to continuously move the cursor to the right direction using a portable mouse, Even if the finger is stopped on the right side 173, the right side light detection area 173 among the four unit light detection areas 176 can continuously sense the position of the finger. This method is particularly effective when the photodetector 100b and the light source 100a are integrated on the same substrate and can be manufactured in a small size. In order to implement each of these methods, the configuration of the control unit 103 becomes somewhat different. For example, if the user wants to continuously move the cursor to the right direction using a portable mouse, the user may detect the light steering sensor 100. In the structure in which the finger must be continuously moved to the right side, the controller 103 is configured to sense the movement, and when the user wants to continuously move the cursor in the right direction, the user stops the finger at the right side of the area where the light steering can be sensed. Even if this is done, the controller continuously moves to the right side in such a way that the controller 103 senses the moving direction by using the amount of light detected in each of the independent light detection areas.

The key input unit 102 serves to enable setting and operation of a function required by a user. That is, when the position of the mouse pointer is determined, an item corresponding to the position can be selected. The key input unit 102 corresponds to a left button, a right button and a wheel button of a general mouse.

The controller 103 receives a signal from the movement determining unit 101 and the key input unit 102, recognizes a distance, a direction, and a button input according to the movement, and transmits the corresponding coordinate value to another electronic device through the short range wireless communication unit. Play a role. The electronic device 120 also includes a short range wireless communication unit 121, and the mouse pointer of the electronic device 120 moves according to the value received from the portable mouse 110.

The short range wireless communication unit 104 may include a baseband unit (not shown), an RF transceiver (not shown), and an antenna (not shown). The RF transceiver receives a signal from the baseband unit and converts it into a signal suitable for transmission, and the signal is transmitted through an antenna. The short range wireless communication unit 121 of the electronic device 120 is formed of similar components, and receives a signal from the short range wireless communication unit 104 of the portable mouse so that the electronic device can recognize the movement of the mouse. Short-range wireless communication may use Bluetooth, ZigBee, and the like.

Furthermore, the portable mouse may have a memory (not shown) or a display portion (not shown). The memory performs a buffer function so that the processed data and necessary data are temporarily stored, and the display unit is a user interface device that displays the overall state of the portable mouse, user input information, and the like so that the user can visually know. The display unit is usually implemented by using a liquid crystal display (LCD).

3, the light source unit 200a and the light detector 200b are integrated into one integrated device. Light generated by the light source unit 200a passes through the lens to become parallel light 202. Then, the light reflected from the surface 203 is detected by the photodetector 200b in the form of a speckle pattern and converted into an electric signal in the form of current / voltage in accordance with the intensity of the light. The electric signal is determined in a distance and direction by the movement determining unit shown in FIG. 1, and its value is transmitted to the electronic device through the short range wireless communication module.

The light source unit 200a and the photodetector 200b may be formed in a shape including a light emitting region and a light receiving region by dividing the regions on the same semiconductor substrate. This will be described later with reference to FIG. 5, the details of which are described in patent application No. 2006-89048 filed on Sep. 14, 2006 by the applicant, which is incorporated in the present application.

Referring to FIG. 4, the light generated by the light source unit 301 mounted on the mobile phone camera passes through the lens 302 to become parallel light 303. Light reflected from the surface 304 is detected by the photodetector 300. As described with reference to FIG. 1, the distance and direction of the image detected by the light detector are determined by comparing the change of the image with time in the movement determiner, and the value is transmitted to the controller.
