Referring to fig. 4, a light emitting control method of a touch device according to the present invention includes the following steps:
obtaining touch information corresponding to at least one touch object on the touch input layer 10, and obtaining force information of the force sensor 40 corresponding to the touch object (S10): when a touch object (e.g., a finger or a stylus) operates on the surface of the touch input layer 10, the touch sensing unit 30 obtains touch information (e.g., the number of objects, position information, etc.) of the touch object, and the force sensor 40 obtains force information corresponding to the force applied by the touch object to the touch input layer 10. In one embodiment, the touch sensing unit 30 obtains the touch information of the touch object according to the capacitance change, and the control unit 50 further calculates the force information obtained by each of the force sensors 40 to obtain the force applied by the touch object.
Changing a light emitting mode of the light emitting module according to at least one of the touch information and the force information (S20): when a user operates the touch input layer 10 with the touch object, the control unit 50 uses at least one item of information of the touch information and the force information of the touch object as a basis for changing the light emitting mode of the light emitting module 20. In an embodiment, the control unit 50 can adjust the light emitting modes of the light emitting module 20, such as the brightness, the flicker or the flicker frequency, according to the calculated magnitude of the force applied by the touch object. In an embodiment, the control unit 50 can adjust the brightness, the flicker frequency, or the light emitting mode of the light emitting module 20 according to the obtained touch information. In an embodiment, the control unit 50 first determines the touch event triggered by the touch object according to at least one of the touch information and the force information, and then adjusts the brightness, the flicker frequency, or the light emitting mode of the light emitting module 20, such as whether to emit light or not, according to the touch event and at least one of the force information and the touch event. Therefore, the user can intuitively know whether the currently triggered touch event is established or what the input touch state is by changing and adjusting the light emitting mode of the light emitting module 20.
The following describes different light emission modes by specific embodiments, and the following description is made with reference to the structures of fig. 1 and 2:
referring to fig. 5, in a normal state, when there is no touch object, the light emitting mode of the light emitting module 20 may be a predetermined state, such as no light emitting or a low light emitting brightness (e.g. 30% of the maximum brightness).
Referring to fig. 6, when the user touches the touch input layer 10 with the index finger 61, the control unit 50 determines that the index finger 61 is a touch event such as a single-finger touch or press on the touch input layer 10 according to the touch information that the type of the object is a finger, the number of the objects is 1, and the displacement of the index finger 61 is not greater than a predetermined value, and the control unit 50 changes the luminance of the light emitting module 20 according to the touch event, for example, from 30% of a predetermined state of non-light emission or maximum luminance to 60% of a higher luminance (maximum luminance), so that the user can intuitively know the touch event that the single-finger touch or press is triggered through the luminance change presented by the touch input layer 10. Further, when the pressing force of the index finger 61 is changed, a further command may be triggered (e.g., a touch event triggering a double click, etc.), and if the pressing force of the index finger 61 is larger, the luminance is made higher, so that the change of the pressing force is reflected by the change of the luminance.
Referring to fig. 7, when the user touches the touch input layer 10 with the index finger 61, the control unit 50 determines that the index finger 61 is performing a touch event such as a single-finger touch or press on the touch input layer 10 according to the touch information that the type of the object is a finger, the number of the objects is 1, and the displacement of the index finger 61 is not greater than a predetermined value, in addition to changing the light emitting brightness of the light emitting module 20, a light spot 101 is formed on the area of the touch input layer 10 corresponding to the index finger 61, so that the user knows the touch event that the single-finger touch or press has been triggered, and knows the current touch position. Further, when the force applied by the pressing down of the index finger 61 is changed, a further command may be triggered (e.g. a double-click event is triggered) and if the force applied by the pressing down of the index finger 61 is larger, the brightness of the light spot 101 is higher, or the light emitting range of the light spot 101 is larger, so that the change of the force is reflected by the change of the brightness and the range.
Referring to fig. 8 and 9, when a user touches the touch input layer 10 with an index finger 61 and a middle finger 62, the control unit 50 determines that the index finger 61 and the middle finger 62 are touch events of double-finger scrolling (scrolling) on the touch input layer 10 according to the touch information that the type of the object is a finger, the number of the objects is 2, the displacement directions of the index finger 61 and the middle finger 62 are the same, and the displacement amount is greater than a preset value, and the control unit 50 changes the light emitting mode of the light emitting module 20 into blinking light, i.e. a light (as shown in fig. 8) and a dark (as shown in fig. 9) light emitting mode according to the touch event that the double-finger scrolling is triggered, so that the user can clearly know that the touch event of the double-finger scrolling is triggered, and further, when the pressing force of the index finger 61 and the middle finger 62 changes, further commands (such as a changing speed, etc.) may be triggered, the frequency of the flicker light at this time may be changed by the force applied by the pressing down. In one embodiment, the larger the pressing force applied by the index finger 61 and the middle finger 62, the higher the frequency of blinking light, and the variation of the light emitting frequency is used to reflect the variation of the pressing force.
Referring to fig. 10 and 11, when a user touches the touch input layer 10 with a forefinger 61 and a thumb 63, the control unit 50 determines that the forefinger 61 and the thumb 63 are touch events that are Zoom-out (as shown in fig. 10) or Zoom-in (as shown in fig. 11) on the touch input layer 10 according to touch information that the type of the object being touched is a finger, the number of the object is 2, the displacement directions of the forefinger 61 and the thumb 63 are opposite, and the displacement amount is greater than a predetermined value, and the control unit 50 displays a light bar 104, 105 at a position near a side of the touch input layer 10 to represent a Zoom-in or Zoom-in touch event according to the touch event being Zoom-out or Zoom-in. Further, as the distance between the index finger 61 and the thumb 63 gradually decreases for a zoom-out event (as shown in FIG. 10), the length of the light bar 104 decreases accordingly; when the distance between the index finger 61 and the thumb 63 is gradually increased in a zoom-in event (as shown in fig. 11), the length of the light bar 105 is increased, thereby showing the degree of change of the zoom-in or zoom-out.
Referring to fig. 12 and 13, when the user touches or presses the touch input layer 10 with the index finger 61 with a single finger, and determines that the pressed position of the index finger 61 corresponds to a specific trigger command (e.g. other multimedia control functions such as adjusting device volume or fast turn/playback) according to the position information, the control unit 50 displays a light bar 106, 107 on the side according to the touch event and the specific trigger command, further, when the pressing force of the index finger 61 changes, the triggered command may be influenced to a certain extent, for example, the volume is adjusted or fast turn/playback, if the pressing force of the index finger 61 is larger, the longer the length of the light bar 106 is, the faster the adjusting speed or fast turn/playback speed is, and if the pressing force of the index finger 61 is smaller, the shorter the length of the other light bar 107 is, the slower the adjustment speed or spinning/playback speed of the volume is indicated.
Referring to fig. 14 and 15, when the user carelessly places the palm 64 on the touch input layer 10 and is idle, the control unit 50 changes the light emitting mode of the light emitting module 20 to be blinking light, i.e. a dark (as shown in fig. 14) or bright (as shown in fig. 15) light emitting mode, according to that the touch event is an idle object, so as to remind the user that an idle object is placed on the touch input layer 10.
In summary, the control unit 50 changes the light emitting mode of the light emitting module 20 according to the touch information or the force information, so as to intuitively feed back the touch information or the force information input by the user to the user on the touch device in real time, so that the user can know whether the user wants to input the electronic device without waiting for the specific instruction triggered or the specific function started on the electronic device, and the user can directly determine whether the user wants to input the electronic device by changing the light emitting mode, thereby improving the convenience of use and reducing the probability of misoperation.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
