In order to make the objects, the technical solutions and the advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

FIG. 1 and FIG. 2 are schematic diagrams showing the structure of two types of handheld touch devices provided by an embodiment of the present invention. For convenience of description, only parts related to the present embodiment are shown.

With reference to FIG. 1 and FIG. 2 , the handheld touch device provided by the embodiment of the present invention has a touch display screen 1 , which displays an operation interface for the user and manually touches the application on the operation interface. Program. Different from the traditional touch terminal with a mechanical button on the side, the touch sensing component 2 is provided on at least one side or the back of the handheld touch device, and the touch sensing component 2 is specifically a touch screen (such as a capacitor). A touch screen or a resistive touch screen includes a grip portion 21 and an operation portion 22 . The grip portion 21 is configured to sense a hand-held motion, and the operation portion is configured to sense a click and a slide motion. When the grip portion 21 senses a hand-held motion, the triggering operation portion 22 enters a working state to sense a click. And sliding actions to achieve various preset target operations by sensing user clicks and swipe actions, the preset target operations including moving the application on the operation interface to move the more remote application on the operation interface To the position where the finger can reach. Of course, the operation unit 22 can further implement functions such as power switch, volume adjustment, brightness adjustment, and the like by clicking or sliding operations.

When the touch sensing unit 2 is disposed on one side of the touch device, when the holding portion 21 senses the hand movement, the operation unit 22 on the same side is triggered to start working. By holding the touch device with one hand, the touch sensing component 2 on the holding side can be touched, and operations such as clicking, sliding, etc. can be performed, thereby realizing functions such as power switch and volume adjustment, and the touch on the operation interface cannot be touched by the finger. When the application is clicked, the current interface can be moved to the direction of the finger by clicking or sliding the operation part, thereby moving the pre-touched application icon to a position that the finger can touch, and then setting the touch sensing component 2 on one side, Solve the problem of inconvenient operation in a single hand. Similarly, when the above-described touch sensing component 2 is disposed on the back side, it is also convenient to perform a single hand holding operation.

It can be understood that it is feasible to implement various functions by the operation unit 22. Specifically, the correspondence between the gesture and the function can be established in advance, for example, the click action corresponds to the power switch, the up and down slide corresponding to the adjustment volume, the left and right slide corresponding to the mobile application, etc. The implementation can be done by software.

As shown in FIG. 2, when the touch sensing component 2 is disposed on both sides of the touch device, when the touch device is held, both the left and right holding portions 21 sense the holding action, and the touch device is The grip signals on both sides recognize whether the user is a left hand grip or a right hand grip (described later in detail), and then the operation portion 22 on the grip side performs normal operation while the operation portion 22 on the other side does not operate. At this time, regardless of whether the user holds the touch device with the left hand or the right hand, they can borrow The above-mentioned power switch, volume adjustment, brightness adjustment, and mobile application functions are realized by the touch sensing unit 2 on the touch holding side. Therefore, the touch sensing component 2 is disposed on both sides of the touch device, and the user can be distinguished from the left and right hand grips to facilitate different usage habits.

Referring to FIG. 2 further, when the touch sensing component 2 is disposed on both sides of the handheld touch device, the operating portion 22 and the holding portion 21 on both sides are symmetrically disposed.

Further, the grip portion 21 and the operation portion 22 can adopt different touch sensing components, as shown in FIG. Different areas of the same touch sensing component can also be used, as shown in FIG.

Regardless of whether the same component or different components are used, the operation part includes a sliding area and a click area, and the sliding area and the click area may not be distinguished, and the same area is used, as shown in FIG. 5, that is, in the same area, the click action can be recognized, and The sliding motion can be recognized, because the gestures are different and the sensing signals are different, so it can be distinguished. Alternatively, the sliding zone and the click zone may correspond to different zones, as shown in FIG.

Further, the identification of the sliding operation requires at least two different sensing electrodes, and the recognition of the clicking motion requires only one sensing electrode. Therefore, when the sliding area and the click area correspond to the same area, the area includes at least two sensings. Electrodes, and adjacent sensing electrodes are seen to have slits for sliding recognition. When the sliding area and the click area can correspond to different areas, the sliding area needs to be provided with at least two sensing electrodes, and the click area only needs one sensing electrode. Of course, it is also possible to use multiple electrodes.

The following is a case where the touch sensing component is a capacitive touch screen. For example, the electrode structure and working principle of the holding portion and the operating portion are explained:

1. For the sliding operation of the operating portion 22:

Figure 7-1 provides an inductive electrode structure capable of inductive sliding action, comprising two right-angled triangular sensing electrodes 221, the two sensing electrodes 221 are opposite to each other with a slit in between. When the finger slides from the A electrode (ie, symbol A) to the B electrode (ie, symbol B), the relative area of the finger and the A electrode and the B electrode changes, and the change in the capacitance value is also the same as the change trend of the relative area, and The source of the signal also changes from the A electrode to the B electrode, so the capacitance curve shown in Figure 7-2 appears. As time goes on, the capacitance of the A electrode gradually decreases, and the capacitance of the B electrode gradually increases. For the sensing electrode of this structure, when the capacitance change curve is as shown in Fig. 7-2, it is judged to be a sliding operation.

Figure 8-1 shows another structure of the sensing electrode 222. When the finger slides from the A electrode to the B electrode, the relative area of the finger and the A electrode and the B electrode changes, and the relative area with the A electrode increases with time. Firstly, it remains basically unchanged, then decreases, and then the relative area of the B electrode increases to a fixed value and remains substantially unchanged, and the same change occurs in the capacitance, as shown in Fig. 8-2, therefore, for the structure The sensing electrode is judged to be a sliding operation when the capacitance change curve is as shown in Fig. 8-2.

In this embodiment, the sensing electrodes of other structures may be used, which are not described in this embodiment.

2. Click operation on the operation unit 22:

Figure 9-1 provides a sensing electrode structure that can sense a click action, which is an integral sensing electrode 223. When a finger clicks, the relative area between the finger and the sensing electrode 223 does not change, and the capacitance value abruptly changes to a certain value. Quickly down Drop to the original value, as shown in Figure 9-2, the capacitance curve with this feature represents the click action, the number of sudden changes in capacitance is equal to the number of clicks.

Of course, when the structure of the two sensing electrodes mentioned above is adopted, the click action can also be recognized, and the characteristics of the capacitance change curve are the same as those of the one sensing electrode, except that the sensing signal may be emitted by different sensing electrodes or by two sensing electrodes. The electrodes are simultaneously output.

In summary, when the sliding area and the click area of the operation portion correspond to the same area, a structure in which a plurality of sensing electrodes are combined is required, and the sliding and clicking can be recognized according to the capacitance variation curve, and if the sliding area and the click area correspond to different areas, the sliding is performed. The area adopts the structure of the sensing electrode combination, and the click area can adopt the structure of a single sensing electrode.

3. Hand-held action for the grip portion 21:

Figure 10-1 provides a sensing electrode structure capable of sensing a hand-held motion, comprising two right-angled triangular sensing electrodes 211 with opposite sides of the two electrodes with a slit in between. When the touch device is held, the palm or the finger touches the grip portion 21, and the capacitance remains abruptly changed to a certain value, and the change curve is as shown in FIG. 10-2.

Figure 11-1 provides another sensing electrode structure that can sense the hand-held motion. There is only one sensing electrode 212. When the touch device is held, the capacitance changes to a certain value and remains basically unchanged. The curve is as shown in Figure 11-2. Show.

4. For the identification of the left and right hand grips:

When the touch sensing component 2 is disposed on both sides of the touch device, if the user holds the hand in the left hand, the capacitance of the holding portion 21 on the left side of the device is high, and the right side holds The capacitance of the grip 21 is low, as shown in Figure 12-1.

If the user holds the right hand grip, the capacitance value of the grip portion 21 on the right side of the device is high, and the capacitance value of the left grip portion 21 is low, as shown in FIG. 12-2.

According to the height comparison of the holding capacitance values of the left and right sides, the left hand or the right hand grip can be judged, thereby triggering the operation portion 22 on the holding side to enter the working state, and closing the operation portion 22 on the other side to avoid interference with the motion recognition.

If the touch sensing component 2 uses a resistive touch screen, the above electrode structure can also be used, but only two layers of electrodes are needed, which will not be described in this embodiment.

The handheld touch device provided by the embodiment of the present invention has the touch sensing component disposed on one side or the back thereof, which can recognize the sliding or clicking operation of the user, thereby realizing functions such as power switch, volume adjustment, and application program movement, and is convenient. The single-hand grip operation of the large-sized touch device can effectively distinguish the left and right hand grips by providing the above-mentioned touch sensing components on both sides of the touch device, adapting to the usage habits of different people, and improving the use of the touch device. flexibility.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the present invention. Within the scope of protection.
