Description

electronic device

technical field

The present invention relates to an electronic device, and in particular to an electronic device capable of identifying types of input tools.

Background technique

In the busy and compact life of modern people, it has become a very common living habit to emphasize convenience and efficiency in everything. Take handheld devices such as mobile phones or personal digital assistants as an example. In addition to having features such as powerful functions and compact size, users also expect to be able to turn on and execute required functions in a very short time. This is especially true for functions that users use more often, such as writing text messages or checking call logs. If the user can quickly activate some commonly used functions when operating the handheld device, the convenience of using the handheld device will certainly be improved.

In order to meet the above requirements, manufacturers of handheld devices set hot keys corresponding to specific commonly used functions on the keyboard or shell of the handheld device at the beginning of the design. Accordingly, when the user presses the hot key, the corresponding frequently used function can be quickly opened, thereby shortening the time required for searching and opening the function. For example, some mobile phone manufacturers will set a button on the side of the mobile phone to enable the camera function. When the user presses this button, the camera function of the mobile phone can be activated immediately.

However, with the trend of hand-held devices getting smaller and smaller, the space available for manufacturers to set hot keys is very limited. In addition, the user's requirements for the appearance of the handheld device cannot be ignored. In order to ensure that the appearance of the handheld device meets the requirements of simplicity and beauty, the manufacturer must control the number of hotkeys during design. There are many hotkeys to meet the needs of quick access to frequently used functions.

Because of this, only a very small number of functions in the handheld device have corresponding hotkeys for users to quickly activate. However, when the user wants to execute a function that has no corresponding hotkey, he must perform the opening action through the operation menu. Since most of the menus of the handheld devices are in a tree structure, users may need to click to enter multiple sub-menus before they can find the desired function options. For some frequently used functions, if the above-mentioned method must be used to start and execute each time, it will inevitably consume a lot of operating time, which will cause a lot of inconvenience in use.

Detailed ways

With the current handheld devices, users can only quickly open some specific functions by pressing hotkeys. However, the number of hotkeys on handheld devices is limited. A user interface with commonly used functions is bound to increase the convenience of operating the handheld device. The present invention is based on the above point of view and further develops a user interface operation method and a handheld device using the method. In order to make the content of the present invention clearer, the following specific examples are given as examples in which the present invention can actually be implemented.

FIG. 1 is a flow chart illustrating an operation method of a user interface according to an embodiment of the present invention. Please refer to FIG. 1 . This embodiment illustrates the detailed steps of how the handheld device automatically switches the corresponding user interface according to different input tools when the user is operating a handheld device. Wherein, the handheld device includes a mobile phone, a personal digital assistant, or a smart phone, etc., and the scope thereof is not limited here.

When the user uses an input tool to operate the handheld device, first, as shown in step 110, the handheld device receives an input signal in a user interface. Then in step 120 , according to the area, pressure, temperature, or image sensed by the touch-sensing device when the input tool touches or approaches the touch-sensing device, the tool type of the input tool is determined accordingly. Finally, as shown in step 130, the handheld device converts and displays the corresponding user interface according to different types of tools.

In this embodiment, the handheld device displays corresponding user interfaces according to different types of tools. For the convenience of description, in the following embodiments, it is an example to distinguish two different input tools, such as a stylus (stylus) and a user's finger, and to switch the corresponding user interface according to the two different tool types. The flow process is used to further illustrate the present invention. Any number of tool types may then be included within the scope of the present invention.

In the following embodiments, the user interface corresponding to the stylus is a general user interface including all functions of the handheld device, while the user interface corresponding to the finger is a common function interface displaying some functions of the handheld device. The functions displayed on the frequently used function interface can be preset by the user according to his habits or needs.

In this embodiment, there are multiple methods to determine the type of the input tool, and different determination methods require different hardware designs, as shown in the block diagrams of the handheld device in FIGS. 2A to 2D , which will be described sequentially below.

The handheld device in FIG. 2A includes a display 210 , a touch sensing device 220 , and a processor 230 . The display 210 is used to display a user interface, and the touch sensing device 220 is, for example, a touch panel (touch panel), which is used to detect the operation of the input tool and generate an input signal according to the operation of the input tool. The processor 230 is coupled to the display 210 and the touch sensing device 220 for determining the tool type of the input tool, and switching the corresponding user interface according to the tool type.

The touch sensing device 220 of FIG. 2A includes a resistive sensor device 240 . The resistive sensor can sense the contact position and pressure when the input tool is operated, so the input signal provided by the touch sensing device 220 includes information such as the contact position and pressure of the input tool. It is worth noting that the resistive sensor can only provide an input signal from one contact point at a time, and the contact points are distributed within the contact area between the input tool and the resistive sensor, as shown in FIGS. 3A and 3B . FIG. 3A shows the contact points t-1 to t-4 of the stylus. Because the contact area of the stylus is small, the contact points are concentrated. FIG. 3B shows the contact points t-1 to t-4 of the fingers. Since the contact area of the fingers is larger, the contact points are scattered. Since the resistive sensor can only provide an input signal of one contact point at a time, the processor 230 must continuously record the information of the input signal within a certain period of time, calculate its variation range, and then judge the input tool according to the size of the variation range. type.

Taking the four contact points in FIGS. 3A and 3B as an example, assume that the input signal generated by the contact point t-i is (Xi, Yi, Pi), where i can be 1, 2, 3, or 4. Xi is the X coordinate of the contact position of t-i, Yi is the Y coordinate of the contact position of t-i, and Pi is the contact pressure of t-i. Processor 230 may calculate the average values of position and pressure respectively as follows:

X coordinate average: Xa=(X1+X2+X3+X4)/4

Y coordinate average: Ya=(Y1+Y2+Y3+Y4)/4

Average pressure: Pa=(P1+P2+P3+P4)/4

Then the variation ranges of position and pressure can be calculated respectively as follows:

X coordinate variation range: Xd＝|Xa-X1|+|Xa-X2|+|Xa-X3|+|Xa-X4|

Y coordinate variation range: Yd＝|Ya-Y1|+|Ya-Y2|+|Ya-Y3|+|Ya-Y4|

Pressure range: Pd＝|Pa-P1|+|Pa-P2|+|Pa-P3|+|Pa-P4|

As for how to determine the tool type according to the variation range of the position and the pressure, the details are shown in the flow charts of FIGS. 4A to 4C , which will be described sequentially below.

FIG. 4A is a flow chart of a method for identifying an input tool type executed by the processor 230 of FIG. 2A . The process in FIG. 4A is to determine the tool type according to the variation range of the contact position. Firstly, in step 410, the detection of the contact of the input tool is started, and in step 420, the X and Y coordinates of the contact point are recorded at intervals of a preset sampling time. Then in step 430 it is checked whether the number of samples is sufficient, if the preset number of the processor 230 is met, the process proceeds to step 440, otherwise returns to step 420 to continue recording.

Next, at step 440 , calculate the variation ranges Xd and Yd of the contact position, and at step 450 check whether Xd<Vx and Yd<Vy, where Vx and Vy are preset ranges of the processor 230 . If the variation ranges of the two coordinates are both smaller than the corresponding preset range, the processor 230 determines in step 460 that the type of the input tool is a stylus, and converts the user interface into a corresponding common user interface. Otherwise, the processor 230 determines in step 470 that the type of the input tool is a finger, and converts the user interface into a corresponding common function interface.

FIG. 4B is a flowchart of another input tool type identification method executed by the processor 230. The process in FIG. 4B is to determine the type of the tool according to the variation range of the contact pressure. The processor 230 records the contact pressure of the input tool every sampling time at step 421 , calculates the variation range Pd of the contact pressure at step 441 , and then checks whether Pd<Vp at step 451 , where Vp is the preset range of the processor 230 . If Pd<Vp, the processor 230 determines at step 460 that the type of the input tool is a stylus, and converts the user interface into a corresponding common user interface. Otherwise, the processor 230 determines in step 470 that the type of the input tool is a finger, and converts the user interface into a corresponding common function interface. The remaining steps in FIG. 4B are the same as those in FIG. 4A and will not be repeated here.

FIG. 4C is a flow chart of another input tool type identification method executed by the processor 230. The process in FIG. 4C is to determine the tool type according to the variation range of the contact position and the pressure at the same time. The processor 230 records the contact position and pressure of the input tool every sampling time in step 422, calculates the variation range Xd, Yd of the contact position and the variation range Pd of the contact pressure in step 442, and then checks in step 452 whether Xd<Vx, Yd<Vy and Pd<Vp. If yes, the processor 230 determines at step 460 that the type of the input tool is a stylus, and converts the user interface into a corresponding common user interface. Otherwise, the processor 230 determines in step 470 that the type of the input tool is a finger, and converts the user interface into a corresponding common function interface. The remaining steps in FIG. 4C are the same as those in FIG. 4A and will not be repeated here.

Next is another identification method of the input tool type under another hardware design, please refer to FIG. 2B and FIG. 5 . FIG. 2B is a block diagram of a handheld device according to another embodiment of the present invention. The main difference between FIG. 2B and FIG. 2A is that the touch sensing device 220 in FIG. device 221. A capacitive sensor is structured with a plurality of sensor pads arranged in an array. The sensing pad will only have a capacitive effect on a conductor large enough to sense the contact or proximity of the conductor. Fingers are conductors that cause the sensor pad to sense. If the stylus is made of a conductor and the size is large enough, the sensor pad can also be sensed. Capacitive sensors generally use a scanning method for sensing, so multiple sensing pads can sense at the same time or within a short period of time. The processor 230 in FIG. 2B can calculate the size of the sensing area according to the number of sensing pads where sensing occurs, so as to distinguish whether the input tool is a finger or a stylus.

FIG. 5 is a flow chart of a method for identifying the type of an input tool executed by the processor 230 of FIG. 2B . Firstly, in step 510 , the contact or proximity of the input tool is detected at intervals of sampling time, and then in step 520 , it is checked whether there is a sensing pad for sensing. If not, return to step 510 to continue detection. If so, go to step 530 , and count the number of sensing pads in the capacitive sensor 250 that generate a sense when the input tool operates the touch sensing device 221 within a predetermined period of time. Then, at step 540 , it is checked whether the above-mentioned number of sensing pads is less than a preset value of the processor 230 . If the number of sensing pads is less than the preset value, the processor 230 determines at step 550 that the type of the input tool is a stylus, and converts the user interface into a corresponding common user interface. Otherwise, the processor 230 determines at step 560 that the type of the input tool is a finger, and converts the user interface into a corresponding common function interface. The above preset value can be set according to the density per unit area of the sensing pad.

2C is a block diagram of a handheld device according to another embodiment of the present invention. The main difference between FIG. 2C and FIG. 2A is that the touch sensing device 220 in FIG. 2A is replaced with a touch sensing device 222 including a temperature sensor 260 . In this embodiment, the processor 230 determines the tool type according to the tool temperature when the input tool touches or approaches the touch sensing device 222 . Please refer to FIG. 1 and FIG. 2C at the same time. When the user uses an input tool to operate on the touch sensing device 222, the processor 230 will receive a corresponding input signal (step 110). At this time, the processor 230 detects the tool temperature input during tool operation through the temperature sensor 260, and compares the tool temperature with a preset temperature (such as the average value of room temperature and body temperature). If the tool temperature is lower than the preset temperature, the processor 230 determines that the input tool is a stylus, otherwise, determines that the input tool is a finger (step 120 ). Next, the processor 230 displays the corresponding common user interface or common function interface on the display 210 according to the tool type, as described in the previous embodiment (step 130 ).

In addition to using the difference in area, pressure and temperature to determine the type of tool, in the embodiment of FIG. 2D , the processor 230 can also use image recognition technology to determine the type of tool. Please refer to FIG. 1 and FIG. 2D at the same time. FIG. 2D is a block diagram of a handheld device according to another embodiment of the present invention. The main difference from FIG. 2A is that the touch sensing device 220 in FIG. Sensing device 223. When the user uses an input tool to operate on the touch sensing device 223 , in step 110 , the processor 230 receives an input signal through the touch sensing device 223 . Next at step 120, the processor 230 controls the image pickup device 270 to pick up the image including the input tool, and judges the type of the tool according to the features or dimensions of the input tool in the image. For example, the processor 230 can obtain features such as the edge profile of the input tool in the image through image recognition technology, so as to determine the type of the tool. Or calculate the size of the input tool in the image, and compare it with the size of the reference object to determine the type of tool. If the processor 230 determines that the input tool is a stylus, then at step 130 the common user interface is displayed through the display 210 . If the processor 230 determines that the input tool is a finger, then at step 130 , the common function interface is displayed through the display 210 .

It is worth mentioning that the processor in the handheld device can adjust the size of the options of the user interface when converting and displaying the user interface according to different types of tools. For example, when the processor determines that the input tool is a stylus, as shown in FIG. 6 , the options on the user interface 600 are displayed in a normal size. However, when the processor determines that the input tool is the user's finger, it will enlarge the options of the user interface to a size that can be manipulated by the finger, as shown in the user interface 700 in FIG. operate. The above-mentioned options include items such as icons (icons) or images (images) that can be selected with input tools.

In addition to switching different user interfaces according to the type of input tool, the handheld device of the present invention can also perform various preset functions in different ways according to the type of input tool, as shown in the flow chart of FIG. 8 . FIG. 8 is a flowchart of a user interface operation method performed by a handheld device according to an embodiment of the present invention. The process is detailed below. First, the processor of the handheld device receives an input signal through the touch sensing device (step 810), determines the type of the input tool that generates the input signal (step 820), and then executes a preset function according to the tool type (step 830). For example, the preset function may be to switch the corresponding user interface according to the type of tool (step 840 ), and the relevant details have been included in the previous embodiments, and will not be repeated here. The preset function in step 830 may also be to enable or disable a specific function according to the tool type (step 850 ). The processor can also perform other preset functions according to the type of tool, which is not limited to the above examples.

The specific function of step 850 may be a user interface panning function, a user interface scrolling function (scrolling), or both (step 860 ). For example, when the input tool is a stylus, the user interface translation and scrolling functions are disabled, and when the input tool is a finger, the user interface translation and scrolling functions are enabled, so that the user can pan or scroll the displayed content of the user interface by moving the finger.

The detailed flow of step 860 is shown in Figure 8B. Firstly, in step 861, it is judged that the type of the input tool is a finger, and the translation and scrolling functions of the user interface are enabled. In step 862, it is checked whether the contact or proximity state of the finger has been released, that is, whether the finger has left the touch sensing device. If not, execute the user interface translation function in step 863, so that the user interface can be translated with the movement of the user's finger. On the other hand, if the finger has left the touch sensing device, it is checked in step 864 whether there is movement while the finger is leaving. If there is no movement, the process ends here. If there is movement, then enter step 865, execute the user interface scrolling function, and let the user interface scroll along with the moving direction of the finger.

Alternatively, the specific function of step 850 may be a multiple selection function (step 870). For example, when the input tool is a stylus, enable the multi-selection function, allowing the user to use the stylus to select multiple data items or function items on the user interface at the same time, and turn off the multi-selection function when the input tool is a finger, so that the user can only Select a single item. Because the precision of the finger is not as good as that of the stylus, it is easy to make a wrong selection, which can improve the accuracy and efficiency of use.

The detailed flow of step 870 is shown in Figure 8C. Firstly, in step 871, it is judged that the type of the input tool is a touch pen, and the multiple selection function is enabled. Then in step 872, it is checked whether the area where the stylus touches or approaches the touch sensing device has any options covered. If not, the process ends here. If so, all options covered by the contact area are selected at step 873 .

In yet another aspect, the specific functions of step 850 may include a drawing brush function and a drawing eraser function (step 880 ). For example, when the input tool is a stylus, enable the drawing brush function and disable the drawing eraser function, so that the user can use the stylus to draw. On the other hand, when the input tool is a finger, turn off the drawing brush function and turn on the drawing eraser function, allowing the user to use the finger as an eraser to erase the previous drawing.

In addition, the processor can also enable or disable other specific functions according to the tool type, which is not limited to the above examples.

The handheld device in the above embodiments can be extended to a general electronic device, and the various method processes in the above embodiments can also be executed by the operating system or application program of the handheld device or the electronic device to integrate functions of hardware such as the electronic device. The above-mentioned operating system or application program can be stored in a computer-readable recording medium, and can be executed by the processor of the electronic device, and its operations are basically the same, and will not be repeated here.

In the embodiments shown in FIGS. 2A to 2D , the display and the touch sensing device are two independent components, wherein the display is used to display the user interface, and the touch sensing device is used to receive input signals.

In addition, the touch display 920 is used to receive the operation of the input tool, and the touch sensing device 920 has a touch sensing plane 920a. It should be noted that since the touch-sensitive display 920 is located in the casing 910, there is a height difference between the casing 910 at the edge of the opening 910a and the touch-sensing plane 920a (as shown in area A), and the height difference For example, it is about 1 mm. In other words, the moving range of the input tool is limited by the opening 910a.

In addition, the processor 930 is coupled to the touch-sensitive display 920 and used for determining the type of the input tool. Like the previous embodiments, the processor 930 can determine the type of the input tool according to the area, pressure, temperature, or image of the touch sensing device 924 when the input tool operates. Likewise, according to different determination methods, the touch sensing device 924 may include a resistive sensor. Alternatively, the touch sensing device 924 may include a capacitive sensor. Alternatively, the touch-sensitive display 920 may include a temperature sensor. Alternatively, the touch-sensitive display 920 may include an image pickup device for picking up images including input tools. As for the details of the judging process and the execution of the preset functions, etc., which have been seen in the previous embodiments, the description will not be repeated. It should be noted that although the methods for displaying different user interfaces may vary according to the types of input tools, the judging methods for displaying different user interfaces are not limited to the judging methods disclosed above. In addition, the result of determining the type of the input tool is not limited to only determine the displayed user interface, and the processor can also determine to drive other programs or perform other actions based on the result.

In this embodiment, the touch-sensitive display 920 includes a display 922 and a touch-sensitive device 924 . However, in other embodiments, the display 922 and the touch sensing device 924 can also be integrated into a single module. In addition, the display 922 and the touch sensing device 924 are respectively coupled to the processor 930 . In this embodiment, both the display 922 and the touch sensing device 924 are disposed in the casing 910 , and the opening 910 a exposes part of the touch sensing device 924 . In addition, the touch sensing device 924 is located above the display 922 , and the touch sensing device 924 has a touch sensing plane 920 a for receiving operations of input tools. Some components will be described in detail below.

The first conductive film 9244a is disposed on the transparent substrate 9242, and the second conductive film 9244b is disposed above the first conductive film 9244a. In this embodiment, the material of the first conductive film 9244a and the second conductive film 9244b is, for example, indium tin oxide (ITO) or other transparent conductive materials. The protection layer 9246 is disposed on the second conductive film 9244b, and the protection layer 9246 has a touch sensing plane 920a.
