Abstract

The utility model relates to a realization device of a mobile phone mouse, which comprises a mobile phone module and an optical finger navigation module, wherein the mobile phone module comprises a mobile phone baseband chip, and the optical finger navigation module is connected with the mobile phone baseband chip and used for detecting the moving direction and speed of a finger and outputting data in the mode of relative coordinates; and the output data of the optical finger navigation module is converted into a corresponding mouse operating instruction and sent to a computer connected with the mobile phone baseband chip in a wired or wireless mode by the mobile phone baseband chip. By integrating the optical finger navigation module inside the mobile phone with USB and Bluetooth functions, the utility model can easily realize the functions of the mouse by only touching and moving the finger of a user on the optical finger navigation module and has high sensitivity and simple and convenient operation.

Description

A kind of implement device of mobile phone mouse

Technical field

The utility model relates to electronic device field, relates in particular to a kind of implement device of mobile phone mouse function, particularly relates to a kind of implement device of mobile phone mouse function of integrated optical finger navigation module.

Background technology

For the business people who often goes on business, notebook computer and mouse must be carried, but because artificial carelessness, the unusual malfunctioning situation of Trackpad in mouse or the notebook computer operating process often appears leaving behind, particularly for those important business situations, these artificial carelessness might be given own or company brings some unnecessary loss, in order to address the above problem, occur some in the market and had the mobile phone of mouse function, because it is simple to operation, has been subjected to a lot of clients' favor.

Yet, the implementation method that existing this class has the mobile phone of mouse function generally has two kinds, a kind of method is that the function element of conventional mouse (left and right press key, optics, roller) is combined with mobile phone, realized the mouse function of mobile phone, this method has not only increased the volume of mobile phone, and has brought certain challenge for the structural design of mobile phone; Another method is that the original function of mobile phone (button, touch-screen, acceleration transducer) is further expanded, the input operation of analog mouse, though this method has been saved hardware cost, service speed is slow, and sensitivity is lower, uses comparatively inconvenience.

Summary of the invention

At the deficiency of prior art, the purpose of this utility model is to provide a kind of implement device of mobile phone mouse function, and the user only need point to touch on photoelectricity finger navigation module and move, and just can easily realize mouse function, and is highly sensitive, simple to operation.

The technical scheme that realizes the present utility model purpose is as follows:

A kind of implement device of mobile phone mouse, comprise mobile module and photoelectricity finger navigation module, mobile module comprises mobile phone base band chip, and described photoelectricity finger navigation module is connected with mobile phone base band chip, be used to detect the moving direction and the speed of finger, with the form dateout of relative coordinate; Mobile phone base band chip is converted into corresponding mouse action instruction with the dateout of photoelectricity finger navigation module, and is sent to connected computer by the mode of wired (USB) or wireless (bluetooth).

The utility model moves by the touch of measuring finger, and is translated into corresponding mouse control order by in the inner integrated optics finger navigation of the mobile phone with USB and Bluetooth function module, thereby has reached the purpose of control computer.

Operation principle:

1, under the mobile phone mouse function opening, when finger touches on photoelectricity finger navigation module when mobile, photoelectricity finger navigation module requires baseband chip to move the numerical value that changes by the finger that the I2C interface reads its measurement on two-dimensional plane by the mode of interrupting.

2, systems soft ware is converted into numerical value change under the two-dimensional plane coordinate with the digital signal of photoelectricity finger navigation module output, thereby extrapolates the moving direction and the distance of finger.

3, systems soft ware transfers result of calculation to corresponding packet according to consensus standard according to the connected mode (USB or bluetooth) of this moment mobile phone and computer, is sent to computer then.

4, under the mobile phone mouse function opening, after mobile phone enters battery saving mode, close photoelectricity finger navigation module automatically, withdraw from behind the battery saving mode and recover again.

It is a variety of that mobile phone realizes that the method for a certain function has usually, and the user often more pays attention to operate simple and practical method.Particularly as the function of this class of mouse, operation is simple more good more for the user.The utlity model has advantages such as highly sensitive, easy to operate.

Embodiment

How further specify the utility model below in conjunction with accompanying drawing realizes:

As shown in Figure 1, form, comprise modules such as radio frequency, LCD, camera, touch-screen and power management in the mobile module by mobile module and optical finger navigation module; Optical finger navigation module 2 links to each other by three GPIO with mobile phone base band chip 1, wherein two GPIO are as the SCL and the SDA of I2C bus, another one GPIO is as the external hardware interrupt pin, to realize operations such as the resetting of 1 pair of photoelectricity finger navigation of mobile phone base band chip module 2, setting, reading of data.The hardware and software resource consumption all seldom, can too much not increase the burden of original cell phone system.

As shown in Figure 2, when the mobile phone mouse function is opened, according to following steps:

Step S200: beginning.

Step S201: initialization photoelectricity finger navigation module 2, configuration relevant register.

Step S202: configuring external hardware interrupts pin is high level triggering mode and opens interrupters.

Step S203: the touch of finger on photoelectricity finger navigation module moves whether triggered interruption, if down trigger is changeed step S204; Otherwise change step S203.

Step S204: read numerical value on photoelectricity finger navigation module X, Y two direction of principal axis by the I2C bus.

Step S205: the numerical value change on two direction of principal axis of measuring with the last time compares, thereby draws the moving direction and the distance of finger.

Step S206: judge the connected mode of mobile phone and computer, if the USB connected mode is changeed step S207, if the bluetooth connected mode is changeed step S208.

Step S207: according to USB HID agreement the moving direction of finger is become the packet of USB HID standard device with range coding, change step S209.

Step S208: according to the bluetooth equipment agreement moving direction of finger is become the packet of bluetooth standard equipment with range coding, change step S209.

Step S209: send packet.

Step S210: judge whether mobile phone enters battery saving mode, if mobile phone enters battery saving mode and then changes step S211; Otherwise, change step S202.

Step S211: finish.
