Airborne mouse cursor displacement speed control method

An aerial mouse control method, and in particular an aerial mouse control method for controlling a displacement speed of a cursor by changing an inclination angle of an aerial mouse.

The mouse is a computer peripheral input device. With the development of wireless technology, through wireless technologies such as Bluetooth or infrared, the mouse no longer needs a physical line connection, that is, the control signal can be transmitted to the computer to control the cursor movement by radio or the like. However, such a mouse still needs to operate on a plane, and the plane for operating the wireless mouse is also quite limited. For example, on a smooth glass plane, it cannot be used normally because the mouse cannot be judged to move. There is a computer peripheral input device called the air mouse. For example, the "three-dimensional space control device" disclosed in the Republic of China Patent Publication No. 00187190, such a mouse does not require a physical line to connect the computer, and does not need to restrict the operation location. . The user can control the upstream movement of the screen by holding or moving such a mouse in a three-dimensional space.

However, when the air mouse is operated, the user's wrist or elbow is not supported, and it is not easy to operate the air mouse compared to the mouse that is generally placed on the desktop. For example, when a user wants to click on an icon and drag the pattern to a specific location, it often happens that the cursor cannot be moved to the pattern to be clicked, or the drag pattern cannot be used. The pattern is dragged to a specific location. Adjusting the sensitivity of the air mouse directly through the mouse driver may help the user to accurately click or drag the object to the specified position, but this reduces the displacement speed of the cursor. When the long-distance moving cursor operation is required, the sensitivity of the aerial mouse is lowered, which makes the user's operation difficult.

In view of the fact that when the user uses the air mouse, it is not easy to accurately control the cursor and the like, and the object of the present invention is to control the movement of the cursor by controlling the change of the angle of the air mouse and to accurately stop the cursor and the area to be selected.

To achieve the above objective, the airborne mouse cursor displacement speed control method comprises the following steps: first, reading the horizontal tilt angle detected by the tilt sensor; and then, determining that the horizontal tilt value is greater than or equal to the preset stop angle, according to the level The inclination value and the maximum displacement speed are used to calculate the displacement speed of the cursor; then, when the horizontal inclination value is less than the preset stop angle and the horizontal inclination value is not changed, the movement of the cursor is stopped; after that, the horizontal inclination value is determined to be smaller than the preset stop angle and the horizontal inclination is When the value changes, the cursor is moved in a small amount or a single point.

The tilt sensor may be a gyroscope, an accelerometer, and a micro-electromechanical system tilt sensor, etc., which can detect the horizontal angle between the air mouse and the ground.

According to the cursor movement speed control method of the air mouse according to the preferred embodiment of the present invention, the displacement speed of the air mouse can be adjusted by pressing a specific key or a combination key, which can be a mouse and a keyboard. Button combination, mouse button, keyboard button.

According to a preferred embodiment of the present invention, the cursor movement speed control method of the air mouse detects whether the horizontal tilt value changes within a preset time, and if there is a change, determines that there is a change, and if there is no change, It is judged that there is no change. When it is determined that the horizontal inclination value is less than the preset stop angle and the horizontal inclination value changes, the cursor is moved once by a single point, and the cursor is moved according to the X, Y-axis component of the horizontal inclination and the direction pointed, and the cursor is moved to a screen. Pixel distance.

As can be seen from the above, the present invention controls the speed of movement of the cursor by the tilt angle of the airborne mouse. Through the small angle change of the air mouse, the user can control the micro movement of the cursor (or move the distance of one screen pixel at a time), and control the cursor to stop moving by controlling the air mouse to not flip when it is less than a set angle. . Therefore, the ability of the air mouse to control the precise positioning of the cursor can be effectively improved, and the aerial mouse can be operated by the user.

The detailed description of the present invention and the detailed description of the present invention are set forth in the following detailed description of the embodiments of the present invention, which is to be understood by those skilled in the art to understand the technical contents of the present invention and to be implemented according to the present disclosure. The related objects and advantages of the present invention will be readily understood by those skilled in the art.

The apparatus of the present invention and its wiring method will be described in detail in the following preferred embodiments. However, the concepts of the present invention are also applicable to other ranges. The following examples are merely illustrative of the objects and methods of the present invention and are not intended to limit the scope thereof.

Before describing the cursor displacement speed control method of the airborne mouse, the aerial mouse detail configuration will be described. "1A" is a schematic diagram of the operation of the air mouse, and "1B" is a schematic diagram of the internal structure of the air mouse. Please refer to "1A" and "1B" in combination. The user holds the aerial mouse 130 and tilts to the left. At this time, the tilt sensor 134 of the air mouse 130 detects the tilt angle, and the microprocessor 132 transmits the mouse signal to the computer 110 through the wireless signal transceiver module 136 and the wireless signal transceiver 140 according to the mouse signal generation. The cursor 122 in the control screen 120 is moved from right to left.

"Fig. 2" is a flow chart of the method for controlling the displacement speed of the airborne mouse cursor. Referring to FIG. 2, the airborne mouse cursor displacement speed control method includes the following steps: first, reading the horizontal tilt value detected by the tilt sensor (step S210); and then determining that the horizontal tilt value is greater than or equal to one. When the stop angle is preset, the displacement speed of the cursor is calculated according to the horizontal inclination value (step S220); if the horizontal inclination value is smaller than the preset stop angle and the horizontal inclination value is not slightly changed (for example, the air mouse is slightly shaken, but is regarded as If the stationary tilt angle is less than the preset stop angle but the horizontal tilt value in the unit time has a slight change (ie, the change in the unit time is greater than a preset value) When the angle is balanced, a slight movement of the cursor is performed, for example, a single point movement (step S240). Please note that the determining step S220 can perform the determination of step S230 or S240 sequentially or simultaneously.

In this embodiment, for example, an accelerometer is used as an airborne mouse embedded tilt sensor to detect the tilt angle of the aerial mouse, and other such as a gyroscope or a MEMS tilt sensor can be used to detect the air mouse. The dip element can also be used as an angle sensor inside the air mouse.

The displacement speed of the cursor is as follows: one is to give the corresponding cursor displacement speed according to the "level" of the air mouse tilt. First, a plurality of inclination levels are pre-divided, for example, the inclination angle is divided into 0 groups of equidistant inclination levels from 0 degrees to 10 degrees, 11 degrees to 20 degrees, 21 degrees to 30 degrees, and 81 degrees to 90 degrees; The maximum displacement speed preset by the mouse is used to set the displacement speed of the cursor corresponding to these inclination levels. For example, the maximum displacement speed is 100 pixels per second, and the inclination level of 0 to 10 degrees is set to move per second. 1 screen pixel distance, 11 degrees -20 degrees tilt level is set to move 10 screen pixels per second distance, 21 degrees -30 degrees tilt level is set to move 20 screen pixels per second distance (depending on Other types of tilt angles are moved by the distance per second). Then, it is judged whether the read horizontal inclination value is at the inclination level, and the cursor movement is controlled according to the cursor displacement speed corresponding to the belonging inclination level.

Another calculation method for the displacement speed of the cursor is to directly read the horizontal inclination value according to the ratio of the maximum rotation angle (the preset rotation angle of the air mouse) and the maximum displacement speed preset by the air mouse. Directly proportionally calculate the displacement velocity of the cursor. The formula for calculation can be expressed as:

When the user operates the air mouse, the user can also use a specific button or a combination of keys (such as a button on the air mouse, a button on the keyboard, or a combination of an air mouse and a button on the keyboard) to adjust the preset maximum displacement speed. To increase/decel the movement speed of the cursor.

Overall, since the moving speed of the cursor is proportional to the tilt angle of the air mouse, when the read horizontal tilt value is larger, the cursor is controlled to move at a faster speed; therefore, the ordinary person familiar with the skill can also Considering that the horizontal tilt angle can be varied according to the ratio of a linear or nonlinear equation, there are variable acceleration and deceleration speeds.

When the horizontal tilt angle is small, the control cursor moves at a slower speed. In general, when the airborne mouse is level, the cursor movement is stopped. However, the air mouse may have a slight tilt (such as a slight jitter in the user's hand), causing the cursor to stop smoothly. In order to overcome the above-mentioned deficiency, in the embodiment, when the air mouse tilt angle is less than the preset stop angle, it is further determined whether the horizontal tilt value remains balanced or remains unchanged within a predetermined unit time. If the horizontal inclination value does not change, it means that the air mouse has not changed (the air mouse is slightly shaken, but it is considered to be stationary and not rotating), and the control cursor stops moving at this time. If the horizontal inclination value per unit time is not balanced and there is some slight specific change (ie, the change is greater than a preset equilibrium angle), it moves according to the X, Y-axis component of the horizontal inclination and the direction pointed, and The cursor performs a small amount of movement, such as moving a screen pixel distance.

Next, the cursor displacement speed control method of the present invention will be described with reference to the drawings. "3A" to "3D" are schematic diagrams of the mouse turning operation. Please refer to "3A" to "3D" in order. In "3A", the tilt angle is divided into 6 levels. When tilting 0-15 degrees, it is set to level 1 and tilted 15-30 degrees. Set to level 2, and so on to the other 6 levels of tilt range. In this embodiment, the displacement speed of the cursor corresponding to each level of inclination is, for example, 1 screen pixel per second, 1 screen 10 pixels per second, and 20 screens per second. Pixels, Level 4 moves 30 screen pixels per second, Level 5 moves 40 screen pixels per second, and Level 6 moves 50 screen pixels per second. Please refer to "3B", the user flips the air mouse to the right. At this time, it is judged that the horizontal inclination value belongs to the dip level of the fourth level, that is, the vector of the X and Y axis components according to the horizontal inclination and the pointing direction, in per second. 30 screen pixels move. In "3C", the horizontal tilt value read belongs to level 2, and at this time, it moves at 10 screen pixels per second. When the horizontal tilt value is less than the preset stop angle (for example, 15 degrees), as shown in "3D", the air mouse will continuously read the horizontal tilt value and judge the horizontal tilt value within a preset time. There is no change. If there is, the cursor is moved at the speed of each screen pixel; if not, the cursor is stopped immediately.

The cursor displacement speed control method of the present invention will be described by way of an embodiment. "Fig. 4" is another flow chart of the method for controlling the displacement speed of the airborne mouse cursor. Referring to FIG. 4, first, the air mouse's microprocessor reads the combination key (step S410), and determines whether the moving speed needs to be adjusted by determining whether the combination key is pressed (step S411), that is, when the different tilt angles are changed. The speed of movement changes. If the moving speed needs to be adjusted (YES in step S411), the speed ratio is adjusted (step S412), and if it is not necessary to adjust the moving speed (NO in step S411), the horizontal tilt value is directly read (step S413). Then, the balance point of the cursor is adjusted according to the ratio (step S414) to initialize the horizontal state of the air mouse or the balance state (i.e., a micro balance angle that allows the hand to shake without being activated, for example, 5 degrees). When there is tilt data, that is, the horizontal tilt value is not zero (YES in step S415), it is further determined whether the horizontal tilt value is less than a preset stop angle (for example, 15 degrees / step S416), and if not, according to the horizontal tilt value Converting the component of the X and Y axes of the horizontal tilt value to the mouse cursor movement signal according to the ratio of the maximum tiltable angle (step S418); if yes, further determining whether the horizontal tilt value has a slight change in a predetermined unit time (Step S417), if not (NO in step S417), the movement of the cursor is immediately stopped, and if there is a slight change (that is, a change between 5 degrees and 15 degrees / a step S417), a slight or single point is made depending on the inclination direction. The output is moved (step S419).

In summary, the cursor movement speed control method of the aerial mouse of the present invention controls the movement speed of the cursor by the tilt angle of the air mouse, and determines that the air mouse is judged to be air-slip when slightly tilted (ie, less than the preset stop angle). Whether the mouse continues to flip to control the movement of the cursor to stop, so that the air mouse has the following advantages: (1) without changing the speed of the cursor movement by the human interface (soft and firmware interface), it can directly be a specific mouse Press the button or key combination to make adjustments. (2) The user can control the cursor to move quickly by flipping the air mouse at a large angle, while the small angle flipping the air mouse can make the cursor slow or slight displacement. (3) When the cursor moves to a small specific position, there is no need to deliberately maintain the level of the air mouse. Even if the air mouse still has a slight inclination, the cursor can be stopped. (4) When the cursor moves to a small specific position, the cursor can be moved to a small amount or a single point by a slight inclination change of the mouse.
