The cursor control method comprises the following steps:
step S100, detecting the position of a user, and sending a first infrared signal to the user according to the position.
In this embodiment, the cursor control method is applied to a terminal, and the terminal can sense the body limb motion, control the cursor in the display screen of the terminal to move, control the cursor to perform corresponding operations, and the like; thus, in this embodiment, the terminal is provided with a body sensor including a photo sensor, an infrared projector, and an infrared sensor; the photoelectric sensor is used for detecting the position and the distance of a user relative to the display screen in real time; the infrared projector is used for simultaneously sending a plurality of infrared signals to the position where the user is located; the infrared sensor is used for receiving infrared signals of feedback.
In this embodiment, an action database and a custom motion are required to be set in the terminal in advance; the action database is a database generated according to somatosensory actions input by a user; when a user operates the terminal, motion sensing actions for motion sensing control operation can be customized in the terminal, such as: facial movements and limb movements; when the user-defined somatosensory action is completed, the user-defined somatosensory action data, such as: the facial motion data and the limb motion data are stored in the motion database so as to be convenient for analyzing the motion input by the user in the subsequent use.
Of course, in this embodiment, when the limb motion is customized, a corresponding relationship between the limb motion and the control operation needs to be defined; such as: the limb movements can be defined as control cursor movements, and the face movements can be defined as control click operations; the clicking operation comprises a single-click operation, a double-click operation, a left-click operation, a right-click operation and the like; when defining the corresponding relation between the limb actions and the control operation, the terminal generates a corresponding relation table of the limb actions and the control operation, and stores the corresponding relation table so as to facilitate the subsequent analysis of the somatosensory actions input by the user.
I.e. before said step 100, the steps of:
and step 001, presetting an action database for analyzing the somatosensory actions input by the user, wherein the action database is a database generated according to the somatosensory actions input by the user.
In this embodiment, when the self-defining motion is completed, the terminal may turn on the body sensor, and detect, in real time, the position and distance of the user relative to the display screen through the photo sensor in the body sensor; when a user enters the induction range of the photoelectric sensor, the photoelectric sensor sends an electric signal to the terminal; the terminal can then determine the location information of the user through the electrical signal; meanwhile, the terminal can also calculate the distance between the position of the user (the distance between the user and the photoelectric sensor) through the photoelectric sensor so as to determine the proportion of the motion distance of the user body feeling to the cursor movement in the display screen.
When the position and the distance of the user relative to the display screen are detected, simultaneously sending a plurality of first infrared signals to the position of the user through an infrared projector, wherein the first infrared signals are infrared pulse signals; in this embodiment, the infrared projector is disposed opposite to the infrared sensor; the infrared projector can emit a plurality of infrared rays, and the infrared rays emitted by the infrared projector can be sensed by the infrared sensor; when the user inputs the motion of the body, a part of infrared rays are blocked, and therefore, the blocked infrared rays are not received by the sensor.
Namely, in the step 100, the method specifically includes the following steps:
step 110, detecting the position and distance of the user relative to the display screen in real time through a photoelectric sensor;
step 120, when the position and distance of the user are detected, simultaneously transmitting a plurality of first infrared signals to the position of the user through an infrared projector; wherein the first infrared signal is a pulse signal.

and step 232, calculating a movement proportion according to the distance, and calculating movement coordinates according to the action data and the movement proportion.
According to the invention, the second infrared signal is received, and the motion of the body feeling input by the user is analyzed according to the second infrared signal, so that the direction and the distance which the user wants to move are obtained; and calculating the movement proportion by combining the distance of the user, and obtaining the moving distance of the cursor on the display screen according to the proportion so as to facilitate the terminal to control the cursor to move to the corresponding coordinate position, thereby realizing the positioning of the moving position of the cursor.
And step S300, obtaining movement coordinates according to the action information, and controlling a cursor in a display screen to move according to the movement coordinates.
In this embodiment, after the moving coordinates corresponding to the motion sensing motion are obtained by calculation, the coordinates of each moving point of the motion sensing motion are obtained, and at this time, a first coordinate point and a last coordinate point in the moving coordinates can be obtained, and the first coordinate point is taken as an origin, so that a cursor in the display screen is controlled to move to the position of the last coordinate point, and the cursor in the display screen is positioned.
Specifically, when the cursor is controlled to move, the first coordinate point and the last coordinate point are required to be converted, so that the first coordinate point and the last coordinate point are respectively converted into corresponding pulse signals; further locking the position of the cursor in the current display screen and taking the position as an origin; and then, according to the pulse signal of the last coordinate point, controlling a cursor in the display screen to move to the position of the last coordinate point, and locking the position until a user inputs a next instruction.
Namely, in the step 300, the method specifically includes the following steps:
step 310, obtaining a first coordinate point and a last coordinate point in the moving coordinates according to the action information;

and 330, controlling a cursor in the display screen to move according to the pulse signals of the first coordinate point and the last coordinate point.
In this embodiment, after the moving cursor is locked, a somatosensory action may be further input to further perform operation control on the cursor; for example, the movement of a cursor is controlled by limb actions, and the movement direction and position of the cursor follow the direction and position of the limb actions; further, the cursor can be controlled to perform motor operation through facial actions; for example, a face moving toward one direction may perform a left click operation for controlling a cursor, a face moving toward the other direction may perform a right click operation for controlling a cursor, and so on.
I.e. after said step 330, the following steps are also included:
and 340, controlling the cursor to complete corresponding operation according to the action information.
According to the method, the first coordinate point and the last coordinate point in the motion track of the motion are acquired, and the two coordinate points are converted into the corresponding pulse signals, so that a cursor in a display screen is controlled to move; after the cursor is moved, the cursor can be further controlled through the input action information to realize corresponding clicking operation; the cursor in the display screen is controlled through the motion of the body sense, a control mode of a mouse is replaced, the cursor is rapidly positioned, and the operation of a user is facilitated.
