Description

Tactile feedback method and electronic device using the same

The invention relates to a haptic feedback method and an electronic device using the same, in particular to a haptic feedback method capable of providing different haptic feedback according to touch parameters and an electronic device applying the same.

In recent years, mobile terminals equipped with touch input devices that sense external contacts as input signals, such as mobile phones, tablet computers, etc., have been sold on the market to provide users with a brand new UI method. However, such a mobile terminal equipped with a touch input device has some disadvantages. Although the touch interface can provide a full-surface aesthetic effect, it cannot be operated like a mechanical button with actual pressing tactile feedback. The user must look at the screen to know whether the button is pressed, if the electronic device is pressed and read. When the reaction is slow, the user may think that the pressing is not correct and the pressing is repeated. Therefore, some manufacturers have further added the vibration function of the tactile feedback to the touch panel, and at the same time matched the changes of the sound and the display content to create a more sensory experience.

However, most of the market has a tactile feedback mechanism. Electronic devices, mostly using motor actuators, achieve tactile feedback. As long as the touch input device is touched, that is, the drive motor generates vibration, thereby achieving a tactile feedback mechanism. However, this does not take into account the power or time of the touch action, the effect of the vibration is too monotonous. Therefore, there is a need for a haptic feedback method and an electronic device to address the deficiencies of the prior art.

In order to implement the invention, other well-known modules or elements of more detail may also be included. Each module or component may be omitted or modified as needed, and no other modules or components may exist between any two modules.

Next, please refer to FIG. 2, which is a flow chart of the steps of the haptic feedback method according to an embodiment of the present invention; and please refer to FIG. 1 and FIG. 3 together with respect to an embodiment of the present invention. The haptic feedback method of the present invention will be described below with the electronic device 100 shown in FIG. It should be noted, however, that the haptic feedback method of the present invention is not limited to use with the electronic device 100 shown in FIG.

First, step S1 is performed: detecting a contact action on the touch display element to provide a touch signal.

Referring to FIG. 1 , the touch display component 110 can sense a contact input of a contact object such as a finger or a stylus pen, and has a touch sense by a conventional resistive film method, an electrostatic capacitance method, an optical type, a capacitive type, and the like. The detector outputs two-dimensional position information of a contact position (a pressing position of a pressing target such as a finger). It should be noted that the contact input of the touch display component 110 for detecting the contact object is familiar to those skilled in the art, and is not in the specification.

As shown in FIG. 1 , the electronic device 100 is provided with three detecting elements 120a, 120b, and 120c respectively disposed under the left, right, and right sides of the touch display element 110, and corresponding positions are respectively provided with vibration elements 140a, 140b, 140c. . When the user touches the touch display component 110, corresponding to the position of the detecting component 120a, 120b, 120c, the trigger detecting component 120a, 120b, 120c provides a touch signal to drive the corresponding component of the vibration component 140a. , 140b, 140c.

Please refer to FIG. 3, which is a structural diagram of a detecting component according to an embodiment of the present invention. According to an embodiment of the invention, the detecting component 120a includes four capacitive electrodes, which are a first electrode 121, a second electrode 122, a third electrode 123, and a fourth electrode 124, respectively. The first electrode 121 is disposed above the fourth electrode 124, and the second electrode 122 and the third electrode 123 are respectively disposed on the left and right of the fourth electrode 124.
