Detailed Description

Fig. 1 is a schematic diagram of an interactive system 100 according to an embodiment of the invention. The interactive system 100 may include an input device 110 and an electronic device 120. Examples of input device 110 may include (but are not limited to): active stylus (activestyles pen), digital ruler (ruler), digital protractor (reactor), etc.; while examples of electronic device 120 may include (but are not limited to): an all-in-one Personal Computer (PC), a tablet computer, a multi-function mobile phone, and the like; wherein the electronic device 120 is generally larger than the input device 110, but the invention is not limited thereto.

As shown in fig. 1, the input device 110 may include a control circuit 110C (e.g., a microprocessor, a memory, and related circuits),

terminals

111 and 112, a coplanar structure (coplanar structure)114, and a communication module 116 (e.g., a wireless communication module conforming to bluetooth, Wi-Fi, and other communication protocols), and the electronic device 120 may include a processing circuit 122 (e.g., a processor, a memory, a bus, and related circuits), a touch-sensitive panel 124 (e.g., a touch-sensitive panel) and its control circuit 124C, a communication module 126 (e.g., a wireless communication module conforming to bluetooth or Wi-Fi, and other communication protocols), and a display module 128. The architecture of the interactive system 100 may vary so long as it does not interfere with the practice of the present invention. For example: the number, type, arrangement, etc. of the components of any of the input device 110 and the electronic device 120 may vary. Another example is: some components of any of the input device 110 and the electronic device 120 may be integrated into the same module, for example, the touch-sensitive panel 124 and the display module 128 of the electronic device 120 may be integrated into a touch screen.

According to the present embodiment, the control circuit 110C and the processing circuit 122 can be respectively used for controlling the operations of the input device 110 and the electronic device 120, and the

terminals

111 and 112 and the touch-sensitive panel 124 can be used for touch control, in particular, for performing interactive control on the input device 110 and the electronic device 120 through two detection points. Terminal 111 is operable to trigger touch-sensitive panel 124 to detect a detection point P1 corresponding to terminal 111, and terminal 112 is operable to trigger touch-sensitive panel 124 to detect a detection point P2 corresponding to terminal 112, wherein detection point P1 corresponds to the location of terminal 111 on touch-sensitive panel 124 and detection point P2 corresponds to the location of terminal 112 on touch-sensitive panel 124 when input device 110 is placed on touch-sensitive panel 124. In addition, the coplanar structure 114 can be used to arrange the

terminals

111 and 112, and the

terminals

111 and 112 can be located on the same plane, wherein when the input device 110 is placed on the touch-sensitive panel 124, the coplanar structure 114 can face the touch-sensitive panel 124 to allow the touch-sensitive panel 124 to detect the detection points P1 and P2. For example, when the user moves the input device 110 to another location on the touch-sensitive panel 124, the touch-sensitive panel 124 may detect that the distance D between the detection points P1 and P2 remains unchanged. In addition, the

communication modules

116 and 126 can be used to wirelessly communicate the input device 110 with the electronic device 120, respectively, to allow the input device 110 and the electronic device 120 to exchange information, when necessary.

Fig. 2 is a workflow 200 of a method for interactive control according to an embodiment of the invention, wherein the method is applicable to the interactive system 100, the input device 110 and the electronic device 120, the control circuit 110C and the processing circuit 122, and other components shown in fig. 1. The control circuit 110C and the processing circuit 122 may control the respective operations of the input device 110 and the electronic device 120 according to the method. For ease of understanding, the first and second terminals in the workflow 200 can be described as the

terminals

111 and 112, respectively, and the first detection point corresponding to the first terminal and the second detection point corresponding to the second terminal can be described as the detection points P1 and P2, respectively.

In step 210, the electronic device 120 (e.g., the processing circuit 122) may sense the

terminals

111 and 112 of the input device 110 by using the touch-sensitive panel 124 to detect a detection point P1 corresponding to the terminal 111 and a detection point P2 corresponding to the terminal 112. When the input device 110 is placed on the touch-sensitive panel 124, the

terminals

111 and 112 may contact or approach the touch-sensitive panel 124 to allow the touch-sensitive panel 124 to detect the detection points P1 and P2. Since the

terminals

111 and 112 can be fixed by the coplanar structure 114, the distance D (between the detection points P1 and P2) detected by the touch-sensitive panel 124 can be maintained constant and equal to a predetermined distance regardless of whether the input device 110 is moved on the touch-sensitive panel 124 or replaced on the touch-sensitive panel 124.

In step 220, when the touch-sensitive panel 124 detects that the distance D between the detection points P1 and P2 is equal to the predetermined distance, the electronic device 120 (e.g., the processing circuit 122) can indicate that the object placed on the touch-sensitive panel 124 is the input device 110 according to a detection result generated by the touch-sensitive panel 124. For example, an input device database may include a mapping relationship between the predetermined distance and an Identification (ID) of the input device 110, wherein the control circuit 124C may be built in the touch-sensitive panel 124, and the input device database may be disposed in the control circuit 124C (e.g., non-volatile memory therein). Based on the input device database, the touch-sensitive panel 124 may generate the detection result, which may include the identification code. In particular, the input device database may include a plurality of predetermined distances (e.g., the predetermined distances) and a mapping relationship between respective identification codes of a plurality of input devices (e.g., the input device 110), wherein the plurality of input devices include the input device 110, the respective identification codes include the identification codes, and the plurality of predetermined distances include the predetermined distances and are different from each other. Thus, by mapping from the predetermined distance to the identification code, the touch-sensitive panel 124 detects that the object placed on the touch-sensitive panel 124 is the input device 110.

In step 230, the electronic device 120 (e.g., the processing circuit 122) may control the display content output by the display module 128 to correspond to the input device 110, such as a modified image corresponding to the interactive control, at least according to the detection result. Examples of display content corresponding to input device 110 may include (but are not limited to): a menu of functions of the input device 110, an auxiliary image of the input device 110 (such as a predetermined image representing the input device 110), related information of the input device 110 (such as an icon, a symbol, etc.), and multimedia regarding the input device 110 (such as a movie, a photo, etc.). Under the control of the processing circuit 122, the display module 128 may display an image related to the interactive control (such as a modified image corresponding to the interactive control) for the electronic device 120 to enhance the user experience.

According to some embodiments, one or more steps may be added, modified, or removed from the workflow 200. According to some embodiments, when detecting that the distance D between the detection points P1 and P2 is equal to the predetermined distance, the touch-sensitive panel 124 may output the detection result and the auxiliary information corresponding to the input device 110, wherein according to the detection result and the auxiliary information, the electronic device 120 (e.g., the processing circuit 122) may control the display content output by the display module 128 to correspond to the input device 110.

FIG. 3 shows details of an embodiment of the input device 110. As shown in the right half of fig. 3, the input device 110 can be implemented as an active stylus, and the

terminals

111 and 112 can be disposed on a symmetry axis of the input device 110 and can be respectively located on the left side and the right side of the input device 110. A distance D1 between the center points of the

terminals

111 and 112 may be taken as an example of the predetermined distance. When viewed along this axis of symmetry,

terminals

111 and 112 may overlap in the side view shown in the left half of fig. 3. For ease of understanding, assume that the active stylus identification is ID 1. In step 220, when the touch-sensitive panel 124 detects that the distance D between the detection points P1 and P2 is equal to the predetermined distance, such as the distance D1, the electronic device 120 (e.g., the processing circuit 122) can indicate that the object placed on the touch-sensitive panel 124 is the active stylus according to the detection result (such as the ID1) generated by the touch-sensitive panel 124. In step 230, the electronic device 120 (e.g., the processing circuit 122) may control the display module 128 to display the display content corresponding to the active stylus, such as the menu and related information (such as name, symbol, etc.), at least according to the detection result (such as the identification code ID 1).

FIG. 4 shows details of an implementation of the input device 110 in another embodiment. As shown in the right half of fig. 4, the input device 110 can be implemented as an active stylus, and the

terminals

111 and 112 may overlap in the side view shown in the left half of fig. 4. For ease of understanding, assume that the active stylus identification is ID 2. In step 220, when the touch-sensitive panel 124 detects that the distance D between the detection points P1 and P2 is equal to the predetermined distance, such as the distance D2, the electronic device 120 (e.g., the processing circuit 122) can indicate that the object placed on the touch-sensitive panel 124 is the active stylus according to the detection result (such as the ID2) generated by the touch-sensitive panel 124. In step 230, the electronic device 120 (e.g., the processing circuit 122) may control the display module 128 to display the display content corresponding to the active stylus, such as the menu and related information (such as name, symbol, etc.), at least according to the detection result (such as the identification code ID 2).

FIG. 5 shows details of an implementation of the input device 110 in another embodiment. As shown in the right half of fig. 5, the input device 110 can be implemented as a digital ruler, and the

terminals

111 and 112 can be disposed on a symmetry axis of the input device 110 and can be located on the left side and the right side of the input device 110, respectively. A distance D3 between the center points of the

terminals

111 and 112 may overlap in the side view shown in the left half of fig. 5. For example, the digital ruler may include a solid structure and a virtual structure, in particular, the solid structure may be a rectangular main structure provided with the

terminals

111 and 112, and the virtual structure may be a rectangular secondary structure displayed by the display module 128, wherein the rectangular secondary structure may be an example of the display content corresponding to the input device 110 in step 230, but the invention is not limited thereto. For ease of understanding, it is assumed that the identification code of the digital ruler is ID 3. In step 220, when the touch-sensitive panel 124 detects that the distance D between the detection points P1 and P2 is equal to the predetermined distance, such as the distance D3, the electronic device 120 (e.g., the processing circuit 122) can indicate that the object placed on the touch-sensitive panel 124 is the digital ruler according to the detection result (such as the ID3) generated by the touch-sensitive panel 124. In step 230, the electronic device 120 (e.g., the processing circuit 122) may control the display module 128 to display the display content corresponding to the digital ruler, such as the rectangular substructure and the scale (scale) thereon, at least according to the detection result (such as the identification code ID 3). According to some embodiments, the type and style of the digital ruler may be varied, and the virtual structure may be varied accordingly.

FIG. 6 shows details of an implementation of the input device 110 in another embodiment. As shown in the right half of fig. 6, the input device 110 can be implemented as a digital protractor, and the

terminals

111 and 112 can be disposed on a symmetry axis of the input device 110 and can be located on the left side and the right side of the input device 110, respectively. A distance D4 between the center points of the

terminals

111 and 112 may overlap in the side view shown in the left half of fig. 6. For example, the digital protractor may include a solid structure and a virtual structure, and particularly, the solid structure may be a rectangular main structure provided with the

terminals

111 and 112, and the virtual structure may be an arc/semi-circular sub-structure displayed by the display module 128, wherein the arc/semi-circular sub-structure may be used as an example of the display content corresponding to the input device 110 in step 230, but the present invention is not limited thereto. For ease of understanding, it is assumed that the identification of the digital protractor is ID 4. In step 220, when the touch-sensitive panel 124 detects that the distance D between the detection points P1 and P2 is equal to the predetermined distance, such as the distance D4, the electronic device 120 (e.g., the processing circuit 122) can indicate that the object placed on the touch-sensitive panel 124 is the digital protractor according to the detection result (such as the ID4) generated by the touch-sensitive panel 124. In step 230, the electronic device 120 (e.g., the processing circuit 122) may control the display module 128 to display the display content corresponding to the digital protractor, such as the arc/semi-circular sub-structure and the scale thereon, at least according to the detection result (such as the ID 4). According to some embodiments, the type and style of the digital protractor may be varied, and the virtual configuration may be varied accordingly.

For ease of understanding, the plurality of input devices may include the example of the input device 110 in the embodiment shown in fig. 3-6, wherein the plurality of predetermined distances, such as the predetermined distances D1, D2, D3, D4 …, may be mapped to respective identification codes, such as the identification codes ID1, ID2, ID3, ID4 …, of the plurality of input devices, respectively, based on the plurality of mapping relationships in the input device database.

detection lines

124V or 124H), the distance between the respective centerlines of any two adjacent lines is d, wherein the distance d may be equal to 4.2(mm), or 6(mm), or other predetermined value. In example (a), when the detection points P1 and P2 are located on the horizontal line or the vertical line, the design value of the predetermined distance (such as any one of the predetermined distances D1, D2, D3, and D4 …) is preferably greater than or equal to the distance D, so as to allow the touch-sensitive panel 124 to correctly detect the distance D. In example (b), when the detection points P1 and P2 are located on the diagonal, the design value of the predetermined distance (such as any one of the predetermined distances D1, D2, D3, and D4 …) is preferably greater than or equal to the distance (r x D) to allow the touch-sensitive panel 124 to correctly detect the distance D, where r may be 1.4142 … or a simplified value thereof such as 1.5.

In step S16, the electronic device 120 (e.g., the processing circuit 122) may control the electronic device 120 to display a corresponding user interface around the input device 110.

According to some embodiments, one or more steps may be added, modified or removed from the workflow 300.

According to some embodiments, the touch mechanism of the touch-sensitive panel 124 may be varied, and the input device 110 may be varied accordingly. Examples of the touch mechanism may include (but are not limited to): capacitive touch mechanisms, electromagnetic touch mechanisms, and the like.
