Description

Method for implementing user interface and related electronic device

The present invention relates to a method for implementing a user interface and related electronic devices, and more particularly to a user interface implementation method for a touch screen, having high customization flexibility and avoiding control items from obscuring the main picture. Related electronic devices.

Various electronic devices that can implement touch functions with touch screens, such as mobile phones, digital cameras, digital video cameras, tablets, notebook computers, desktop computers, and all-in-one computers, etc. Because of its friendly operation and user intuition, it has become one of the mainstream development of modern consumer electronic devices.

Since touch screens have been widely accepted by the public, electronic devices with touch screens have also been used to simulate remote controls for other electronic devices. Please refer to FIG. 1 and FIG. 2; when a device 10 is used to simulate the remote controllers RC[1] and RC[2] for different controlled devices D[1] and D[2], respectively, FIG. 1 and 2 is a diagram showing the implementation of a user interface on device 10 in accordance with a conventional technique. Device 10 is an electronic device having a touch screen 12. The controlled devices D[1] and D[2] are electronic devices providing the source; the controlled device D[1] has a dedicated remote controller RC[1] controlled by the remote control signal from the remote controller RC[1] Sa[1], and provides a source signal V[1] to a relay device 14 according to the signal Sa[1]. For example, the controlled device D[1] may be a CD player, a hard disk player or a set-top box, etc., and provides dynamic video and audio content in the signal V[1]. Similarly, the controlled device D[2] corresponds to the dedicated remote controller RC[2], and provides the source signal V[2] to the relay device 14 according to the remote control signal Sa[2] sent by the remote controller RC[2].

The relay device 14 receives the signals V[1] and V[2], and carries the signal content in the signal Vm for transmission to the device 10, and the device 10 can play the content in the signal Vm to the touch screen 12. In one embodiment, the relay device 14 can include a video box and a router (not shown). The video box receives the signals V[1] and V[2], and converts the signals V[1] and V[2]. The signal is suitable for network transmission (for example, a packet), and the router converts the converted signal code into a signal Vm. In another embodiment, the relay device 14 itself has integrated the functions of the video box and the router into one.

In order to enable the user to control the controlled devices D[1] and D[2] as the source via the device 10, the relay device 14 learns and records the remote control that can be issued by the remote controllers RC[1] and RC[2]. The signal and the corresponding function; the touch screen 12 of the device 10 receives the manipulation of the controlled devices D[1] and D[2], and accordingly sends a corresponding signal Sm to the relay device 14. After receiving the signal Sm, the relay device 14 remotely controls the controlled devices D[1] and D[2] according to the signal Sm with the corresponding remote control signals Sb[1] and Sb[2] respectively, so that the controlled device D[ 1] Performs the corresponding function with D[2]. In this way, the user can manipulate the controlled devices D[1] and D[2] via the device 10 (with the relay device 14), without having to remotely control the controlled device with the remote controllers RC[1] and RC[2]. D[1] and D[2]. The remote control signals Sa[1], Sa[2] and Sb[1], Sb[2] may be infrared signals, and the signals Sm and Vm may be wireless communication signals.

In order to facilitate the user to remotely control the controlled devices D[1] and D[2] by using the above technology, in the conventional user interface, the device 10 displays a menu on the touch screen 12, allowing the user to select the remote control to be controlled. Control device D[1] or D[2]. If the user selects to remotely control the controlled device D[1], the device 10 further displays an analog panel on the touch screen 12 to simulate the remote controller RC[1], as shown in FIG. The analog panel includes a plurality of control items (such as buttons) simulated by the touch area; when the user touches the control items, the device 10 and the relay device 14 can control the controlled device by using the signals Sm and Sb[1]. D[1]. Similarly, if the user wants to remotely control the controlled device D[2], the device 10 displays another analog panel of the analog remote controller RC[2] on the touch screen 12, as shown in FIG.

However, the conventional user interface of Figures 1 and 2 also has disadvantages. First of all, this remote user interface lacks the flexibility of customization; because the analog panel of the remote control has a fixed style, the user can have a lower margin. For example, although there are many buttons on the remote control, only a few of them are commonly used by users; however, the conventional analog panel still displays multiple (or all) remote control items, which not only allows the user interface to be used. It becomes complicated and not friendly, and increases the chance of accidental touch. The analog panel also needs to occupy a larger area on the touch screen 12. When the touch screen 12 displays the main content of the video content in the signal Vm, since the remote control analog panel is opaquely overlaid on the main screen, it will occupy (shadow) 40% to 60% of the screen display range. This will make it impossible for the user to see the complete home screen and miss the wonderful details of the main screen; this effect is especially serious for the content of the instant signal, because the user may no longer be able to replay the video content that has been played.

To overcome the shortcomings of the prior art, one of the objects of the present invention is to provide a method for implementing a user interface on a touch screen, including: performing a setting procedure on the touch screen according to the user's instructions and selection. One or more selection control items are set, and each selection control item corresponds to an optional function and a prompt transparency; when the setting program is completed and the main screen is displayed on the touch screen, the respective control items are completely transparent (100% transparency). The overlay is displayed on the main screen so that the selected control items are hidden in the main screen and do not obscure the main screen. At the same time, the touch screen continuously detects whether the user touches any of the selected control items; if so, The prompt transparency (which may be 100% or less than 100% transparency) corresponding to the touch selection control item is displayed, and the corresponding control item is executed according to the user's touch in the touch selection control item. Choose features. When the setting program ends and the touch screen displays the main screen, if the touch position of the touched user is not in any of the selected control items, at least one adjacent selection control item may be selected according to the touch position, and the control is selected according to the proximity. The prompt transparency corresponding to the item displays its overlay on the main screen. The hint transparency can be lower than the full transparency to alert the user to the location of the touched or adjacent selection control.

It is still another object of the present invention to provide an apparatus for implementing the aforementioned user interface, including a touch screen and a processing module. The touch screen detects the user's touch; the processing module can perform a setting process to set at least one selected control item on the touch screen according to the user's instruction, and each selected control item corresponds to an optional function and a prompt transparency. . When the touch screen displays a main screen, the processing module causes the selected control items to be overlaid on the main screen with full transparency. The touch screen detects whether the user touches any of the selected control items; if so, processes The module can display the touch selection control item by using the prompt transparency, and perform the corresponding selection function according to the user's touch in the touch selection control item.

In order to better understand the above and other aspects of the present invention, the preferred embodiments are described below, and in conjunction with the drawings, the detailed description is as follows:

The technology for implementing the user interface of the present invention can be divided into two stages. First, the user can customize the user interface according to individual needs in a setting program, including selecting a control item commonly used by the user on the touch screen ( And give up the buttons that are not commonly used), customize the size and position of the control items, etc., and set a corresponding prompt transparency for the selected control items. After the setting process is completed, the user-selected control items will be hidden when the main screen is played, but the state of being touched can be maintained; thus, the user can completely view the main screen, and the user can also touch. The screen is manipulated to control the progress of the playback.

Please refer to FIG. 3 to FIG. 16; FIG. 3 to FIG. 15 are diagrams showing the implementation of the user interface of the present invention in a device 30 according to an embodiment of the present invention, and FIG. 16 is a view of FIG. A functional block diagram of device 30. As shown in FIG. 16, the device 30 is an electronic device equipped with a touch screen 32, such as a mobile phone, a palm-type amusement instrument, a portable media player, a digital camera, a digital video camera, a tablet computer, Notebooks, desktops and integrated computers, etc. The touch screen 32 can display a picture in a display range 34 and detect the user's touch (which can be single-point and/or multi-point touch) in a detection range 36. The detection range 36 may coincide with the display range 34 or be smaller than the display range 34 (but included in the display range 34). The device 30 further includes a processing module 38 coupled to the touch screen 32 and controlling the operation of the device 30.

Fig. 3 is a flow chart 100 showing a setting procedure in the apparatus 30, the steps of which can be explained in conjunction with Figs. 4 to 9 as follows.

Step 102: Start setting. The touch screen 32 can detect the touch of the user in the detection range 36, and compare whether the touch action of the user has met a preset start action; if so, the process of setting the process 100 can be started. And proceed to step 104. As shown in FIG. 4, in an embodiment of the present invention, the setting start action may be: there are four touch positions P[1] to P[4] simultaneously moving along the direction A1; that is, the user The process 100 can be initiated by moving four fingers simultaneously along the direction A1.

Step 104: Start the action by the user's setting, and the processing module 38 of the device 30 can call the main control panel used by the setting program and display it on the touch screen 32. Figure 5 shows an embodiment of the main control panel, which sets two touch areas in the detection range 36 and displays them in a graphic (icon) to simulate two touchable The buttons bn[a] and bn[b] are used as a warehouse button and a setting button, respectively. Furthermore, the main control panel may also include explanatory text (not shown) and illustrations to assist the user in setting the program. If the user touches the button bn[a], the process 100 may proceed to step 106; if the user touches the button bn[b], the process 100 may proceed to step 114.

Step 106: The user touches the warehouse button bn[a] to call out a prop column TC, as shown in FIG. In the item bar TC, a plurality of candidate control items T[1]...T[n-1], T[n], T[n+1], etc. can be displayed, and the corresponding graphic simulations are touchable. Buttons; each candidate control item T[n] represents a control item that can be applied to the user interface and corresponds to a candidate function. For example, the candidate control item T[n-1] may correspond to a control item of a “volume control” function, and the candidate control items T[n] and T[n+1] may respectively correspond to the “second channel” and The control of the "previous channel". In addition, each candidate control item T[.] may also correspond to "play", "fast play", "slow play", "second chapter", "previous chapter", "pause play", "power supply" Control items such as "Menu Expansion/Collection" and numeric keys. If the number of candidate control items is too large to be displayed on the item bar TC at the same time, only a part of the control items may be displayed in the item bar TC, and a simulated slider sbr is set and displayed on one side of the item bar TC. , so that the user can scroll the item bar TC and see other candidate control items that are not originally displayed. The touch screen 32 can display a corresponding control item graphic and/or explanatory text in the touch area of each candidate control item T[.].

Step 108: After displaying the item bar TC, the touch screen 32 continuously detects whether the user touches any candidate control item T[n]; if so, the processing module 38 can select the candidate control item according to the user touch. A corresponding selection control item is set, and a corresponding selection function is given to the selection control item according to the candidate function corresponding to the candidate control item, that is, the candidate control function is matched to the candidate function of the candidate control item. As shown in FIG. 7, after the user touches the candidate control item T[n], the touch is continuously moved and the touch position is moved from the inside of the toolbar TC to the outside of the toolbar TC, and the device 30 can be based on The movement of the touch position of the user removes the candidate control item T[n] from the toolbar TC (the candidate control item T[n+1] can be replenished after the candidate control item T[n-1]), and In addition to the toolbar TC, the candidate control item T[n] is set and displayed as an optional control item F[1] to correspondingly indicate the touch area of the selected control item F[1].

In other words, the user can drag the candidate control item T[n] from the toolbar TC to become the selection control item F[1]. Similarly, the user can drag the candidate control item T[n+1] into the selection control item F[2], and drag the candidate control item T[n-1] into the selection control item F[3].

The touch screen 32 will continuously detect whether the user touches any of the selected control items; if so, the processing module 38 sets/updates the user's touch selection control item according to the user's touch in the selected control item. For example, after the user drags the candidate control item T[n] to the selection control item F[1], the user can touch the control item F[1] again and change the touch during the duration of the touch. Position, and the device 30 can follow the position of the selection control item F[1] according to the change of the user's touch position. In this way, the user can drag the selection control item T[n] to the user's preferred location. Similarly, the user can zoom in, zoom out, and/or rotate the touch area to which the control item F[1] belongs by changing the relative position of the two touch positions in the touch area of the control item F[1]. (and the corresponding graphic size and orientation).

Step 110: If the user has selected the selected control item, the toolbar TC can be collapsed; for example, the touch screen 32 can continuously detect whether the user touches the button bn[a], and if so, the processing mode Group 38 will cause toolbar TC to no longer be displayed on touch screen 32. That is, when the user touches the button bn[a] in step 106, since the item bar TC is not expanded and displayed, the processing module 38 can cause the item bar TC to be presented on the touch screen 32; When the user touches the button bn[a] again in step 110, since the item bar TC is displayed, the processing module 38 can cause the item bar TC to collapse. Flow 100 may then proceed to step 112.

Step 112: The touch screen 32 continuously detects the touch of the user in the detection range 36, and the processing module 38 compares whether the touch action of the user has met a preset end action; if so, Proceed to step 120. If no, the process returns to step 106.

Step 114: If the touch screen 32 detects that the user touches the setting button bn[b], the device 30 can set and display a touch area on the touch screen 32 as a setting area SZ, as shown in FIG. As shown, flow 100 may continue to step 116.

Step 116: The touch screen 32 detects whether the user touches in the setting area SZ. If yes, the processing module 38 can set the attributes of each selected control item F[.] according to the user's touch, for example, It is to set a corresponding prompt transparency for each selected control item. That is to say, the user can expand the setting area SZ via the touch of the button bn[b], and perform touch in the setting area SZ to set the corresponding attribute of each selected control item.

Step 118: If the user has set an attribute for each selected control item, the setting area SZ can be collapsed; for example, the touch screen 32 can continuously detect whether the user touches the button bn[b] again, and if so, processes The module 38 can cause the setting area SZ to no longer be displayed on the touch screen 32, and proceeds to step 120.

Step 120: If the user has selected the desired selection control item and/or set the attributes of each selected control item, the main control panel displayed by step 104 can be retrieved. For example, the touch screen 32 can detect the touch of the user in the detection range 36, and the processing module 38 compares whether the touch action of the user has met a preset end action; if so, The buttons bn[a] and bn[b] are made to disappear. As shown in FIG. 9, in an embodiment of the present invention, the setting end action may be: there are four touch positions P[1] to P[4] simultaneously moving in the direction A2; that is, the user can use Four fingers simultaneously touch and move in direction A2 to collapse the main control panel. Flow 100 can then proceed to step 122.

Step 122: End the setting procedure of the process 100. As shown in Fig. 11, when the process 100 ends, the device 30 is ready to customize the user with a user-selected selection control (such as the selection of control items F[1] to F[3]). User interface. The touch areas of the selected control items may not overlap each other, and each touch area is smaller than the detection range 36.

After the process 100 is completed, when the device 30 is to display (play) the main screen, the user interface of the present invention can be implemented according to the process 200 of FIG. 10, so that the user can use the user interface when playing the main screen. The playback of the home screen and/or the operation of the device 30 are controlled. The key steps of the process 200 can be described as follows.

Step 202: When the device 30 is to display/play the main screen on the touch screen 32, the process 200 can be started. The main screen may be a video content screen provided by a multimedia source, and/or a screen when a main program is executed. When the device 30 displays the main screen on the touch screen 32, the processing module 38 causes the respective control items (such as the selected control items F[1] to F[3]) to have complete transparency (ie, 100% transparency). The overlay is displayed on the main screen, as shown in Figure 12; that is, the selection control is hidden in the main screen and does not prevent the user from viewing the main screen.

Step 204: During the playback of the main screen, the touch screen 32 continuously detects whether the user touches any of the selected control items, that is, detects whether the user touches the touch area corresponding to any selected control item; if so, Then proceed to step 206.

Step 206: For the touched selection control item, the processing module 38 of the device 30 accesses the prompt transparency previously set in the process 100, for example, the prompt transparency set in step 116.

Step 208: If the prompt transparency corresponding to the touch selection control item is 100% (complete transparency), proceed to step 210, otherwise proceed to step 212. Different selection controls can correspond to different prompt transparency; or all selected controls can all correspond to the same prompt transparency. If the process 100 is not performed to step 116, the processing module 38 may cause each of the selected control items to correspond to a preset (built-in) prompt transparency.

Step 210: If the prompt transparency is 100%, the processing module 38 will continue to hide the touched selection control items. In other words, the touch control option is repeatedly displayed on the main screen with full transparency.

Step 212: If the transparency is less than 100%, the processing module 38 of the device 30 displays the selected control item according to the prompt transparency, that is, the touch screen 32 is used to prompt the transparency to be touched. The control item is superimposed on the main screen to prompt the user to the touch area of the selected control item. Flow 200 may proceed to step 214.

Step 214: The touch screen 32 continuously detects whether the user touches in the touch area of the touch selection control item; if yes, proceed to step 216.

Step 216: The processor 38 of the device 30 performs an optional function corresponding to the touch selection control item to control the playback of the main screen and/or the operation of the device 30 itself.

Continuing the example of FIG. 11, when the device 30 displays the main screen on the touch screen 32, the selected control items F[1] to F[3] are hidden in the main screen, as shown in FIG. Assume that the prompt transparency corresponding to the control items F[1] to F[3] is 100% (step 208 to step 210), then when the user wants to touch the control item F[1], it can be directly touched. Control position P[a] to touch, as shown in Figure 13. When the device 30 detects that the touch position P[a] and the touch control area corresponding to the control item F[1] overlap each other (refer to FIG. 11), the device 30 can directly respond to the touch of the user. The selection function, for example, is to make the source jump to the next channel; at the same time, the control item F[1] still maintains 100% transparency. Similarly, when the user touches the touch position P[b], the selection function corresponding to the selection control item F[2] can be triggered. When the touch position of the user is moved from P[c] to P[d], since the touch position matches the touch area of the selection control item F[3] (for example, the overlap degree is greater than an identification value), the processing module 38 can perform corresponding selection functions for the movement mode (such as moving direction and moving distance) of the touch position in the touch area, for example, the playback volume is reduced; meanwhile, the control item F[3] is maintained. Complete transparency.

On the other hand, if the prompt transparency corresponding to the control items F[1] to F[3] is less than 100% (from step 208 to step 212), when the user touches the touch position P[a] The processing module 38 displays the graphic of the selection control item F[1] (and its touch area) with the prompt transparency, as shown in FIG. 14 so that the user can know the selection control item F[1] more clearly. s position. After knowing the position of the control item F[1], the user can further touch the control item F[1] to trigger the selection function corresponding to the selection control item F[1].

If the touch position on the touch screen 32 does not match the touch area of any of the selected control items (for example, the overlap between the touch area of each selected control item and the touch position of the user is less than an identification value) The processing module 38 can select one (or more) selection control items that are closest to and/or adjacent to the touch position according to the distance between the touch position and each selected control item, and display the display with the prompt transparency, so that the user A clearer understanding of where to choose controls. As shown in FIG. 15, when the user touches the touch position P[e], the device 30 first displays the selected control item F[3] closest to the touch position P[e] with the prompt transparency. Then, the user can perform further touch in the touch area in the control item F[3], so that the device 30 performs the corresponding selection function according to the touch.

When the device 30 displays a selection control item according to the prompt transparency, the selection control item can be automatically hidden again after a preset period of time. This preset time period can also be set in step 116. Alternatively, the user may not hide the selection control item after touching the selection control item, or may hide the selection control item after waiting for a delay period after the user touches the selection control item. Whether or not to automatically hide the selection control item and/or the length of the delay period after the user touches can also be set in step 116.

In the embodiment of Figure 16, the processing module 38 can be implemented in software, hardware, and/or firmware or a combination of the three. For example, the processing module 38 can include a processor and a memory device (not shown). The memory device can include volatile memory and/or non-volatile memory, and store a user interface code; By executing the user interface code, processes 100 and 200 can be executed to implement the user interface of the present invention. The device 30 may also include other functional blocks and modules (not shown), such as wired and/or wireless communication modules, to enable the user to remotely control other electronic devices via the user interface of the present invention using relay technology. Please refer to FIG. 17, which is a schematic diagram of remotely controlling other electronic devices by the user interface of the device 30 according to an embodiment of the invention. Similar to the relay techniques of Figures 1 and 2, the device 30 can be combined with a relay device 14 to remotely control the controlled devices D[1] and D[2]; for example, the controlled devices D[1] and D[2] ] It can be two electronic devices as sources, providing source signals V[1] and V[2] to the relay device, and having dedicated remote controllers RC[1] and RC[2], respectively. The relay device 14 learns and records the remote control signals Sa[1] and Sa[2] that can be sent by the remote controllers RC[1] and RC[2], and carries the contents of the signals V[1] and V[2]. It is carried in signal Vm for transmission to device 30.

When the process 100 is performed, the user can set the control items of the remote controllers RC[1] and RC[2] as the selection control items F[.]. After the setting process is completed, when the device 30 plays the main screen of the signal Vm, the device 30 can implement the user interface of the present invention according to the process 200, and the touch screen 32 is received through the touch area of each selection control item F[.]. The control performed by the controlled devices D[1] and D[2] is used to issue a corresponding signal Sm to the relay device 14. After receiving the signal Sm, the relay device 14 remotely controls the controlled devices D[1] and D[2] according to the signal Sm with the corresponding remote control signals Sb[1] and Sb[2] respectively, so that the controlled device D[ 1] Performs the corresponding function with D[2].

In summary, the user interface of the present invention has a high degree of customization capability compared to the user interface of the prior art, and allows the user to select (enable) the commonly used control items and decide to use the user's own needs. Control the location of the item, and can eliminate (disabled) useless controls, making the user interface more streamlined and friendly, close to the user's personal needs and usage habits. When playing the main screen, the user interface of the present invention can also greatly reduce/avoid the influence of the control item on the main screen, so that the user can completely view the main screen while continuously controlling.

In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention.
