Abstract

Disclosed is an air mouse implementation method based on a smart phone. The method comprises: installing a software application (APP) on a smart phone; utilizing a camera and an automatic focusing function of the smart phone to extract image data; the software application measuring and determining an up-down or left-right movement direction and a movement distance and a single-click or double-click operation according to a change in the image data; and then sending, to a computer device, the movement direction, the movement distance and the single-click or double-click operation of the illustrated mouse by means of wireless communication, so as to control an operation of the computer device. By means of the method, basic functions of a mouse can be implemented by utilizing a smart phone with a high level of popularity. The method is simple in implementation method, convenient in application and cost-effective.

Description

Smartphone-based aerial mouse implementation method

Technical field

The invention belongs to the field of computer input control, and in particular relates to a method for implementing a mouse.

Background technique

The mouse is an input device of the computer, which is divided into wired and wireless. It is also an indicator for positioning the vertical and horizontal coordinates of the computer display system. It is named "mouse" because it resembles a mouse.

The mouse is divided into a mechanical mouse and an optical mouse according to the working principle of the mouse. The mechanical mouse is mainly composed of a rolling ball, a roller column and a grating signal sensor. When you drag the mouse, the ball is rotated, the roller rotates the roller, and the grating signal sensor installed at the end of the roller collects the grating signal. The photoelectric pulse signal generated by the sensor reflects the displacement of the mouse in the vertical and horizontal directions, and then the movement of the cursor arrow on the screen is controlled by the processing and conversion of the computer program.

Now that the mouse has entered people's daily work and life, people who use computers can't do without the mouse, and people are getting used to using the mouse to control the operation of the computer. With the development of portable computers, especially tablets, more and more people are using tablet computers to go out, but tablets are usually not equipped with a mouse. If you forget to bring a mouse, it will be very difficult.

Summary of the invention

In order to solve the problems in the prior art, the present invention provides a method for implementing an air mouse based on a smart phone, and installing an application by using a popular smartphone. APP, you can realize the function of the traditional mouse.

The invention is achieved by the following technical solutions:

A method for implementing an air mouse based on a smart phone, installing a software application on the smart phone, extracting image data to the software application by using a camera and an auto focus function on the smart phone, the software application is based on image data The change determines the direction of the up and down, left and right movement and the distance of movement, and clicks or double-clicks; then sends the moving direction, moving distance, click or double-click operation of the mouse to the computer device by wireless communication to control The operation of the computer device.

As a further improvement of the present invention, when the mobile phone moves, the same part of the image of the two frames before and after is shifted; according to the offset position, the moving direction of the mouse can be measured, and according to the offset, the moving distance of the mouse can be measured.

As a further improvement of the present invention, when the mobile phone moves vertically downward, the image range of the camera is reduced, and the local content becomes larger; when the mobile phone moves vertically upward, the image range of the camera is enlarged, and the local content becomes smaller; the software application detects After this change, it is determined to be a click action.

As a further improvement of the present invention, the click action is captured 2 times within a preset time, indicating a double tap action.

As a further improvement of the present invention, the computer device is a PC, a notebook computer or a tablet computer.

As a further improvement of the present invention, the wireless communication method is any one of Bluetooth, Wi-Fi, infrared, and ZigBee.

The beneficial effects of the invention are: the smart phone has become a necessity in our daily life With no additional equipment, only one APP software can be installed to realize the basic functions of the mouse. The method for implementing the air mouse based on the smart phone of the present invention is simple in implementation, convenient in application, and has good application value.

detailed description

The invention will now be further described with reference to the drawings and specific embodiments.

The smart phone-based air mouse implementation method of the invention installs a software application APP on the smart phone, extracts image data by using a camera on the smart phone and an auto focus function, and the software application measures the up, down, left and right movement according to the change of the image data. Direction and movement distance, as well as click or double click operation. The moving direction, moving distance, click or double click operation of the illustrated mouse is then transmitted to the computer device by wireless communication to control the operation of the computer device. The computer device can be a PC, a laptop or a tablet. The manner of wireless communication may be Bluetooth, Wi-Fi, infrared, ZigBee, and the like.

The specific implementation principle of the present invention is as follows:

Air mouse movement measurement: As shown in Figure 1, after opening the camera on the mobile phone and automatically focusing, the image information is acquired periodically. When the mobile phone moves up and down (or left and right), the same part of the two frames before and after will be offset. According to the offset position, the mouse can be measured The moving direction, according to the offset, can measure the moving distance of the mouse.

Aerial mouse click calculation: As shown in Figure 2, when the mobile phone moves vertically downwards, the camera captures the image range and the local content becomes larger. When the mobile phone moves vertically upwards, the camera acquires a larger image range and the local content becomes smaller. After the software application detects this change, it is determined to be a click action.

The air mouse double-clicks to calculate: the above-mentioned click action is captured twice in a preset time, indicating a double-click action.

The smart phone has become an indispensable tool in our daily life. It does not need extra equipment. It only needs to install an APP software to realize the basic functions of the mouse. The implementation method of the smart mouse-based air mouse of the present invention is simple to implement. It is easy to apply and has good application value.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
