1 is a functional block diagram of an electronic device 100 in accordance with an embodiment of the present invention. The electronic device 100 includes a processing unit 110, a storage unit 120, a vibration device 130, a display 140, and a touch device 150. The storage unit 120 is configured to store an operating system 121 and one or more applications 122. The processing unit 110 executes the operating system 121 as a work platform, wherein the operating system 121 is, for example, an operating system such as Windows, Android, iOS, etc., which can display a plurality of icons on a desktop or a work column. The application 122 can be a different application corresponding to the icon in the desktop or task bar of the operating system 121. In some embodiments, the touch device 150 can be a touch panel. In other embodiments, the touch device 150 and the display 140 can be integrated into a touch screen 160. For convenience of explanation, the embodiment described later uses the touch screen 160 as an example.

In an embodiment, the operating system 121 can include detecting touch The function is to receive a touch action on the touch screen 160 from a touch object (for example, a finger or a stylus) through the touch screen 160. It should be noted that in the screen presented by the operating system 121 (e.g., the desktop), there are many icons that can be used to quickly execute the corresponding program. When the user uses the touch object to hold the touch screen 160 and slide through the different icons, the operating system 121 can perform the corresponding vibration feedback action by using the vibration device 130, so that the user feels that the touch object has passed. An icon has either stayed on a graphic and its details are detailed later. It should be noted that the vibration device 130 of the present invention can adjust its vibration frequency and its amplitude according to a control signal from the operating system 121.

Figure 2A is a schematic diagram showing the position of a desktop icon in accordance with an embodiment of the present invention. 2B is a schematic diagram showing a desktop area of a desktop in accordance with an embodiment of the present invention. In an embodiment, the desktop icon of the operating system 121 is as shown in FIG. 2A. Although the dimensions of the icons in FIG. 2A look different, the operating system 121 is still in the determination of the touch action. The same size is given to each of the icons for the touch operation, as shown in FIG. 2B. The interval between the illustrations of the area 210 is small. If the touch operation is performed on the touch screen 160 by the touch object 200, the user may not accurately select the specific one because of the viewing angle and the contact area. Illustration.

3 is a schematic view showing a touch object passing through different illustrated regions according to an embodiment of the invention. 4 is a schematic view showing the relationship between a touch action and a vibration action according to an embodiment of the present invention. Referring to Figures 3 and 4 simultaneously, in one embodiment, the vibrating device 130 of the present invention can vibrate with a fixed vibration frequency and change its vibration amplitude. For example, when a touch object touches When the touch screen 160 or the desktop cursor is controlled only by the touch device 150, the operating system 121 determines the effective touch area, such as the touch area 310 (for example, it may be an effective contact area of the finger on the touch screen 160 or Is the effective area of the desktop cursor). When the touch area 310 overlaps with a corresponding illustrated area (for example, the illustrated area 321) and exceeds a certain ratio (for example, 30%), the operating system 121 starts to calculate the touch area 310 in the icon. The duration of the area. When the duration of the stay is longer, the operating system 121 controls the vibration device 130 to increase the vibration amplitude proportionally (or inversely proportionally) until the upper or lower limit of the vibration amplitude of the vibration device 130 is reached, as shown in FIG. . As shown in FIG. 3, if the touch object is pressed on the touch screen 160 and slowly moved toward the moving direction 350, the touch object passes through the illustrated areas 321 to 324, and the touch area is touched. When the 310 passes through different illustrated areas, the vibration device 130 will continue to stay in each of the illustrated areas according to the touch area 310 (for example, the time interval T1~T4 corresponds to the continuous stay time in the illustrated area 321~324) Change its amplitude while changing. It should be noted that, in this embodiment, the fixed vibration frequency set by the vibration device 130 is based on the vibration of the user, for example, 150 Hz, but the invention is not limited thereto.

Fig. 5 is a view showing the relationship between a touch action and a vibration action according to another embodiment of the present invention. Referring to FIGS. 3 and 5 simultaneously, in an embodiment, the vibrating device 130 of the present invention can use a fixed vibration amplitude and change its vibration frequency. For example, when a touch object touches the touch screen 160, the operating system 121 determines the effective touch area, such as the touch area 310. When the touch area 310 overlaps with a corresponding illustrated area (for example, the illustrated area 321) and exceeds a certain ratio (for example, 30%), the operating system 121 will Beginning to calculate the duration of stay of the touch area 310 in the illustrated area. The longer the duration of the dwell time, the operating system 121 controls the vibrating device 130 to increase its vibration frequency in proportion to the upper limit of the vibration frequency of the vibrating device 130. As shown in FIG. 3, if the touch object is pressed on the touch screen 160 and slowly moved toward the moving direction 350, the touch area 310 passes through the illustrated areas 321 to 324, and whenever the touch is performed, When the region 310 passes through different illustrated regions, the vibrating device 130 will continue to stay in each of the illustrated regions according to the touch region 310 (for example, the time interval T1~T4 corresponds to the continuous dwell time in the illustrated regions 321~324). Adjust the vibration frequency by changing it. It should be noted that in this embodiment, the fixed vibration amplitude set by the vibration device 130 is based on the vibration of the user, for example, 0.15 mm, but the invention is not limited thereto. In addition, the processing unit 110 can determine whether the moving speed of the touch object on the touch screen 160 exceeds a predetermined threshold. When the moving speed is greater than the predetermined threshold, the processing unit 110 does not calculate the continuous dwell time of the effective touch area of the touch object on the illustrated area. When the moving speed is not greater than the predetermined threshold, the processing unit 110 further calculates the overlapping ratio of the effective touch area of the touch object on the illustrated area and the duration of the stay.

It should be noted that the electronic device 100 can set the manner in which the vibration device 130 intends to use the fixed vibration frequency or the fixed vibration amplitude in the present invention, as described in the embodiments of FIGS. 4 and 5. No matter what method is adopted, the user's feelings during the touch operation can be effectively improved. FIG. 6 is a schematic diagram showing the relationship between the touch action and the vibration action of the conventional touch feedback method. Please also refer to Fig. 3 and Fig. 6. When the traditional operating system detects the same touch action as shown in Fig. 3, the vibration frequency and vibration amplitude of the vibrating device are solid. Certainly, it will not be adjusted as the touch area 310 continues to stay in the illustrated area. Therefore, if the distances of the two figures are relatively close, the user feels the same vibration frequency and vibration amplitude in a short time (for example, only after the time interval T8), so it is difficult for the user to judge that the current touch object is staying. On that one icon. However, the present invention can adjust the vibration action of the vibration device 130 according to the manner of the fixed vibration frequency or the fixed vibration amplitude and according to the duration of the touch area in the illustrated area, and the user can go through a long time interval (for example, The time interval T6 of Fig. 4 or the time interval T7 shown in Fig. 5) and the different vibration actions when the touch object stays on two different figures. After the user releases the touch object on the touch screen 160, the processing unit 110 executes an application corresponding to the icon staying at the touch object.

FIG. 7 is a flow chart showing a touch feedback method according to an embodiment of the invention. At step S710, the processing unit 110 displays at least one icon on the display 140. In step S720, the touch device 150 detects a plurality of touch actions of the touch object on the touch device 150 (or the touch screen 160), thereby selecting one of the at least one icon, wherein the touch The control object has a touch area on the touch device. In step S730, when the touch area stays in one of the at least one illustration, the processing unit 110 controls the vibration device 130 to vibrate with a fixed vibration amplitude, and according to the touch area in the at least one illustration. A continuous dwell time of the person adjusts the vibration frequency of one of the vibrating devices.

In step S820, the touch device 150 is used to detect a plurality of touch actions of the touch object on the touch device 150 (or the touch screen 160). One of the at least one of the icons is selected, wherein the touch object has a touch area on the touch device. In step S830, when the touch area stays in one of the at least one illustration, the processing unit 110 controls the vibration device 130 to vibrate at a fixed vibration frequency, and according to the touch area in the at least one illustration. A sustained dwell time adjusts the vibration amplitude of one of the vibrating devices 130. It should be noted that the electronic device 100 can preset the manner in which the vibration device 130 intends to use the fixed vibration frequency or the fixed vibration amplitude in the present invention, as described in the touch feedback method of FIG. 7 or FIG. No matter what method is adopted, the user's feelings during the touch operation can be effectively improved.

It should be noted that in other embodiments, the operating system 121 can support the function of a magnifying glass, so that the local area can be enlarged to facilitate the user to view the local area or select the local area. Icon. The touch feedback method of FIGS. 7 and 8 of the present invention can also be applied to the magnifying glass function. Furthermore, although the picture of the local area is enlarged, the operating system 121 does not change the criterion for determining the effective touch area, and still calculates the coincidence ratio of the original effective touch area and the area of the illustrated area. Then, the continuous stay time of the effective touch area staying in the illustrated area is calculated. The vibrating device 130 can then be controlled by means of the fixed vibration amplitude or the fixed vibration frequency in Fig. 7 or Fig. 8, and the vibration frequency or vibration amplitude of the vibrating device 130 can be adjusted accordingly according to the continuous dwell time.
