Abstract

A cursor input method based on the direction of force on the touchpad is to correspond the touchpad of the smart device to its display screen, that is, the horizontal and vertical coordinates of the two correspond to each other; Lightly press the touchpad on the direction of the touchpad corresponding to the target position of the cursor. When the pressure sensor on the touchpad senses that the pressure in the direction of the force is greater than the threshold, the cursor input voltage control mode is activated: the cursor moves on the display screen. to the position corresponding to the contact point on the touchpad, and the speed of movement depends on the amount of pressure sensed by the touchpad. When the position of the cursor after moving on the display deviates from the expected target position, the user reduces the pressure on the touchpad, and when the pressure sensed by the pressure sensor on the touchpad is less than the threshold, the smart device switches the cursor to the traditional After that, the user uses the traditional touchpad input mode to move the finger on the touchpad to adjust the moving track of the cursor to make the cursor move in place.

Description

A Cursor Input Method Based on Touch Pad Force Orientation

technical field

The invention relates to a cursor input method used in smart electronic devices such as notebook computers, PDAs or smart phones, and more precisely, relates to a cursor input method based on the force orientation of a touch panel, which belongs to the technical field of computer equipment applications.

Background technique

At present, the touchpad has become a very widely used cursor input method for notebook computers. Its use is very simple. As long as you touch the touchpad under the keyboard with your finger, the cursor on the display screen will move accordingly. The working principle of the touchpad is: when the user's finger touches the touchpad, its capacitance will change, and the IC controlled by the touchpad will detect the change in capacitance, thereby detecting the direction in which the user's finger moves, and This translates to a coordinate transformation for cursor movement. At the same time, the moving speed of the cursor also corresponds to the moving speed of the user's finger.

In addition, in the prior art, there is a method of placing some contacts arranged according to set rules under the touch panel. When the touch panel senses the pressure of the user's finger contact or movement, the time when different contacts are connected and sequence to detect the position, direction and speed of the user's finger force, which is converted into a corresponding cursor movement. The working principle of this touchpad is similar to the "Little Red Riding Hood Mouse" provided by the ThinkPad notebook computer. The ThinkPad notebook computer can determine the direction and movement of the cursor by detecting the direction and magnitude of the force exerted by the user's finger on the "Little Red Riding Hood Mouse". distance and movement speed.

At present, touch display screens are widely used in smart devices such as computers, PDAs, and smart phones. Users can move and determine the cursor position through fingers or stylus. The working principle is to simply determine the cursor position as the user's finger or touch The pen is located at the point of contact on the touch display.

The advantage of the touchpad is that it is responsive and moves quickly; its disadvantage is that the response is too sensitive, resulting in low positioning accuracy. Due to this shortcoming, a considerable number of notebook computer users still choose to use an external mouse because they cannot grasp and use the touchpad well for cursor input.

In addition, because the existing touchpad cursor input method has high requirements for the movement sensitivity and amplitude of the user's fingers, some people with upper limb diseases or disabilities often feel inconvenient when using the traditional touchpad-based cursor input method. Furthermore, due to the high manufacturing cost of the touch display screen and the fact that users do not want to carry an external mouse, a large number of users have become accustomed to using the touchpad input method. Therefore, in the future, more and more intelligent electronic devices will provide touch-based The cursor input method of the board. However, these new smart devices may be small in size, and it is impossible to provide a touchpad with a large area. In this way, it is even more problematic to use the traditional touchpad cursor input method on these small smart devices similar to the current notebook computer.

Therefore, the subject of how to improve the cursor input method of the traditional touch panel has attracted the attention of relevant technical personnel. People hope to provide a new cursor input mode without changing the user's original operating habits, so as to reduce the requirements for the user and enable the user to control the movement of the cursor on the touch panel more quickly and conveniently. ; On the other hand, it can reduce the requirement on the area of the touchpad, so that the cursor input method based on the touchpad can also be introduced on more and more small smart devices.

Contents of the invention

In view of this, the object of the present invention is to provide a cursor input method based on the force orientation of the touch panel, which is a supplement and improvement to the traditional touch panel cursor input method, and also a supplement without changing the user's operating habits. A new cursor input mode for . This method can not only reduce the requirements for the user, so that the user can control the movement of the cursor on the touch pad more quickly and conveniently; A touchpad-based cursor input method is introduced on small smart devices.

In order to achieve the above object, the present invention provides a cursor input method based on the force direction of the touchpad, which is characterized in that: the method is to correspond the touchpad of the intelligent electronic device to its display screen, that is, the horizontal and vertical directions of the touchpad The coordinates correspond to the horizontal and vertical coordinates of the display screen respectively; when the user wants to move the cursor from the source position to the target position, the user only needs to lightly press the touch pad on the orientation of the touch pad corresponding to the target position of the cursor on the display screen, When the pressure sensor on the touch panel senses that the pressure in the direction of the force is greater than the preset threshold, the cursor input voltage control mode is activated: the cursor moves on the display screen towards the position corresponding to the contact point on the touch panel.

The method further includes the following operations:

When the target position where the cursor moves on the display screen deviates from the user's expected target position, the user reduces the pressure on the touchpad; when the pressure sensed by the pressure sensor on the touchpad is less than the set threshold , the intelligent electronic device switches the cursor input voltage control mode to the traditional cursor input mode; thereafter, the user moves the finger on the touch panel according to the traditional touch panel cursor input mode to adjust the moving track of the cursor, so that the cursor finally Move to the desired target location of the user.

The moving speed of the cursor in the cursor input voltage control mode is determined by the pressure sensed by the touchpad, that is, the greater the pressure sensed by the touchpad, the faster the moving speed of the cursor.

The detection of the pressure sensed by the touchpad in the cursor input voltage control mode is to select the downward vertical pressure, or to select the total pressure including the downward vertical pressure and the horizontal pressure.

The intelligent electronic equipment includes notebook computers, PDAs, smart phones and other intelligent electronic devices provided with touch panels.

The operation of lightly pressing the touchpad on the orientation of the touchpad is performed by the user with a finger or a stylus.

The present invention is a cursor input method based on the force orientation of the touch panel. The method has the advantages of not needing to configure an expensive touch display screen, nor requiring the user to change and abandon the traditional touch panel input method that has been used to, but A supplement and improvement to the traditional touchpad cursor input method, this method is not only more in line with the user's usage habits, but also can be used in conjunction with the traditional method to make up for the shortcomings of the traditional touchpad cursor input method.

Taking a notebook computer as an example, the user can still use its customary traditional cursor input mode on the touch panel, but when the pressure of the user lightly pressing the touch panel exceeds a certain threshold value, the "cursor input voltage control function" of the present invention will be activated immediately. Mode"; and when the user's pressure on the touchpad is less than the threshold, it can return to the traditional cursor input mode. Therefore, adopting the cursor input method of the present invention can reduce the requirements for the user, so that the user can control the movement of the cursor on the touch panel more quickly and conveniently.

Another advantage of the present invention is that the method has significantly lower requirements on the sensitivity and amplitude of the user's finger movement, and is used in conjunction with the traditional touchpad cursor input method, making the touchpad-based cursor input method more convenient for upper limbs. Or people with disabilities use smart electronic devices such as computers or mobile phones.

In the future, more and more intelligent electronic devices may provide cursor input methods based on touch pads. Due to the development of microelectronics technology, the volume of these intelligent electronic devices will become smaller and smaller, and it is impossible to provide large-area touch pads. There will be problems with the traditional touch pad cursor input method. The method of the invention is applicable to a touch panel with a smaller area, and increases the possibility of providing a cursor input method based on the touch panel for small smart devices.

Furthermore, the hardware cost of the method of the present invention is very low, and does not require major changes to the hardware of the intelligent electronic device, as long as a pressure sensor is provided on the touch panel, it can be realized, so mass production is relatively convenient and easy. Since there are a large number of electronic devices using a touch panel for cursor input, the method of the present invention has good prospects for popularization and application.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The present invention is a cursor input method based on the force direction of the touch panel, which corresponds the touch panel of the intelligent electronic device to its display screen, that is, the abscissa and ordinate of the touch panel respectively correspond to the abscissa and ordinate of the display screen ; When the user wants to move the cursor from the source position to the target position, the user only needs to use the finger or stylus to lightly press the touch pad on the orientation of the touch pad corresponding to the target position of the cursor on the display screen. When the pressure sensor senses that the pressure in the direction of the force is greater than the preset threshold, the cursor input voltage control mode is activated: the cursor moves on the display screen towards the position corresponding to the contact point on the touch panel. At this time, the moving speed of the cursor in the cursor input voltage control mode is determined by the pressure sensed by the touchpad, that is, the greater the pressure sensed by the touchpad, the faster the moving speed of the cursor. In the cursor input voltage control mode, the detection of the pressure sensed by the touchpad can select the downward vertical pressure, or select the total pressure including the downward vertical pressure and the lateral pressure.

Of course, there may be a deviation between the target position of the cursor moving on the display screen and the target position desired by the user, and at this time, the user can reduce the pressure on the touch pad; When it is less than the set threshold, the intelligent electronic device will switch the cursor input voltage control mode of the present invention to the traditional cursor input mode; after that, the user can move the finger on the touch pad according to the traditional touch pad cursor input mode to adjust The moving track of the cursor makes the cursor finally move to the desired target position of the user. The intelligent electronic equipment to which the method of the present invention is applicable includes notebook computers, PDAs, smart phones and other intelligent equipment provided with touch panels.

Referring to accompanying drawing 1～3 below, introduce the implementation situation of the inventive method:

Figure 1 is a schematic diagram of a notebook computer display screen. In Figure 1, the lower left corner is the coordinate origin O, the abscissa and ordinate are T _X , _TY respectively, (X ₀ , Y ₀ ) is the current cursor position, and (X _D , Y _D ) is the point where the user wants the cursor to move. target location. Figure 2 is a schematic diagram of a touch panel of a notebook computer. In Fig. 2, the lower left corner is the coordinate origin O, the abscissa and ordinate are t _x , ty _y respectively, and (x _t , y _t ) is the contact position where the user lightly presses the touchpad. Fig. 3 is a schematic diagram of the motion synthesis of the cursor on the display screen of the notebook computer. (X _T , Y _T ) in FIG. 3 is the corresponding position on the display screen corresponding to the contact point (x _t , y _t ) of the touch panel.

Since the coordinates of the touchpad in FIG. 2 correspond to the coordinates of the display screen of the notebook computer in FIG. 1 , the two coordinate systems can choose a plane Cartesian coordinate system, a plane polar coordinate system, or the like. Here we take the planar Cartesian coordinate system as an example. Therefore, if the lower left corner is taken as the coordinate origin O at this time, the corresponding coordinate relationship is: X _T /T _X ＝x _t /t _x , Y _T /T _Y ＝y _t / t _y .

When the user wants the cursor on the display screen to move from the source position (X ₀ , Y ₀ ) to the target position (X _D , Y _D ) (see Fig. 1), the operation steps of the method of the present invention are as follows:

(1) Corresponding to the target position (X _D , Y _D ) of the cursor on the display screen (see Figure 1), the user lightly presses the touch panel on the corresponding position (x _t , y _t ) on the touch panel (see Figure 2) .

(2) When the pressure sensed by the pressure sensor on the touch panel is greater than the set threshold, the smart device starts the cursor input voltage control mode (see Figure 3), and the cursor moves to the position of the display screen corresponding to the contact point of the touch panel (X _T , Y _T ) moves, and its moving speed is related to the pressure sensed by the touchpad: the greater the pressure sensed by the touchpad, the faster the cursor moves, and the detection of the pressure can select the downward vertical direction pressure, or select the total pressure including downward longitudinal pressure and lateral pressure.

(3) If there may be a deviation between the target position (X _T , Y _T ) that the cursor moves on the display screen and the target position (X _D , Y _D ) desired by the user (see FIG. When the pressure sensed by the pressure sensor on the touch panel is less than the set threshold, the intelligent electronic device switches the cursor input voltage control mode to the traditional cursor input mode.

(4) After that, the user can move the finger on the touchpad according to the traditional touchpad cursor input method (see Figure 3) to adjust the moving track of the cursor, and finally reach the target position (X _D , Y _D ) that the user wants the cursor to move .
