The first side 11 includes a display module 111 for displaying a screen, such as an operation interface or a general image of the program, through the display module 111. The display module 111 occupies the first side 11 due to the characteristics of the electronic device such as a tablet computer. The vast majority of the area.

The second side 12 includes a plurality of sensing elements 121. The plurality of sensing elements 121 are disposed in the display range of the display module 111 so that corresponding markings of the sensing elements can be displayed on the display module 111. According to different designs, the plurality of sensing elements 121 can be disposed on one of the left and right sides of the second side 12, or can be disposed on the left and right sides of the second side 12, so as to meet the needs of different users. Not limited to this. In this embodiment, the plurality of sensing elements 121 are provided with a distance sensor (P-sensor), so that when the hand of the user approaches, the corresponding finger positions are sensed according to whether the sensing element 121 is shielded. And at least one sensing signal is sent to the processing module 20 by the at least one sensing component 121, but the type of the sensing component is not limited thereto.

The processing module 20 is disposed in the main body 10 , and is electrically connected to the display module 111 , the plurality of sensing components 121 , and the storage module 30 . The processing module 20 is configured to determine, according to the received at least one sensing signal, at least one target sensing component currently corresponding to each finger of the user, and notify the display module 111 of the corresponding portion of the at least one target sensing component Show at least one tag.

In an embodiment of the present invention, the processing module 20 may be a central processing unit, and the storage module 30 may be a memory or a hard disk device. However, the present invention is not limited thereto, and the processing module 20 may be Hardware, software, firmware or a combination of more than two.

Please refer to Figure 1 and Figure 2 together. 2 is a schematic view showing the operational state of the first embodiment of the portable electronic device 1 of the present invention. As shown in FIG. 2, in the present embodiment, the plurality of sensing elements 121 are divided into a plurality of columns of sensing elements (such as A, B, C, etc. as shown, wherein column A includes A1, A2, A3, etc. The measuring element 121, and so on, wherein the plurality of sensing elements 121 are arranged in only one of the manners, and the buttons or other arrangements of the oblique columns can be configured according to the design, which is not limited to the embodiment.

The processing module 20 determines, according to the received at least one sensing signal, at least one sensing component that senses a position of a user's finger in any one of the sensing elements, and is closest to the at least one sensing component. The sensing element of the two-sided center point O is the target sensing element. Taking the column A as an example, assuming that the finger position is F1, since the finger position F1 spans the sensing elements A1, A2, and A3 in the sensing elements of the A column, the sensing elements will be shielded by the finger position F1, and each corresponding is issued. The sensing signal is sent to the processing module 20. After receiving the sensing signals, the processing module 20 can know that the current finger position F1 corresponds to the sensing elements A1, A2, and A3. Since the fingertip position is at the forefront of the finger position F1, it can be judged that it is currently at A. The sensing element in the column closest to the center point O of the second side is A1, that is, A1 is used as the target sensing element to notify the display module to display the mark at the position relative to the sensing element A1.

Here, the processing module 20 can determine the target sensing elements corresponding to the current fingertips in other ways.

After receiving the sensing signal sent by the sensing component A3, it is further determined whether the sensing signal of the sensing component A2 is received. If the sensing signal of the sensing component A2 is not received, the sensing component A3 is used. As the target sensing component; if the sensing signal of the sensing component A2 is received, it means that the finger also shields the sensing component A2, and can continue to determine whether the sensing signal of the sensing component A1 is received. Then, if it is determined that the sensing signal of the sensing component A1 is not received, the sensing component A2 is used as the target sensing component; if it is determined that the sensing signal of the sensing component A1 is received, it indicates that the finger is also shielded. The measuring element A1, at this time, uses the sensing element A1 as a target sensing element.

Taking C column as an example, assume that the finger position is F2. Since the finger position F2 only corresponds to the sensing element C2 in the C column sensing element, the sensing element C2 is shielded by the finger position F2 and sends a corresponding sensing signal to the processing module 20. After receiving the sensing signal, the processing module 20 can know that the current finger position F2 corresponds to the sensing component C2, and thus can determine the sensing component C2 that is closest to the second center point O in the C column. The target sensing element corresponding to the finger pad is used to notify the display module to display the mark at the position relative to the sensing element C2.

After the processing module 20 determines the state of each column of sensing elements, at least one target sensing element corresponding to the fingertip of the user can be confirmed, so as to notify the display module 111 to display at least one mark at the corresponding position.

It should be noted that the form of at least one mark S is not limited to the embodiment, and may be expressed by different patterns, colors of the virtual buttons or color conversion of the outer frame, and illumination.

As shown in FIG. 1 and FIG. 2, the portable electronic device 1 of the present invention further includes a background sensing component 123 on the second side 12 for sensing whether the distance between the device body 10 and any environmental object is too close. The notification processing module 20 adjusts the sensing distance of the complex sensing element 121 correspondingly. When the background sensing component 123 senses that it is too close to an environmental object (such as a wall or a table top, etc.), the background sensing component 123 notifies the processing module 20 to avoid false positives of the plurality of sensing elements 121 caused by the environmental objects. The sensing distance of the plurality of sensing elements 121 is shortened to avoid affecting the sensing of the finger portion; and even the processing module 20 turns off the sensing function of the complex sensing element 121. In addition, the design of the warning sound can also be used to remind the user. When the background sensing component 123 senses that it has moved away from the environmental object to a certain distance, the processing module 20 is notified to restore the sensing distance of the complex sensing component 121 or turn on the sensing function of the complex sensing component 121. In the embodiment, the plurality of sensing elements 121 also use a distance sensor (P-sensor), but the type of the sensing element is not limited thereto.

In addition, for the different designs of the present invention, it is also possible to determine whether a misjudgment has occurred by the plurality of sensing elements 121 themselves. For example, when the environmental object is too close to the second side of the body, the majority of the sensing elements 121 may sense the presence of the environmental object, and correspondingly emit a plurality of sensing signals. Therefore, when the processing module 20 determines that the sensing signal sent at the same time exceeds a certain number (refer to FIG. 2, the plurality of sensing elements 121 disposed by a single side is taken as an example, and the sensing element that is shielded is set to exceed 4 columns, or more than 12 The sensing signal, because the user only operates with four fingers of one hand in the normal state, that is, the result that may be affected by the environmental object at present, the processing module 20 correspondingly adjusts the sense of the complex sensing component 121. Measuring distance.
