Description

Touch device and touch method

technical field

The invention relates to a touch device, in particular to a touch device with feedback action and a touch method.

Background technique

Today, touch screens and touch pads are more and more widely used. For example, electronic devices such as desktop computers, notebook computers, smart phones, and tablet computers all use touch screens or touch pads for operations. However, current touch screens and touch pads are all designed so that users directly operate on the surface with a touch object (such as a finger or a stylus), which is a unidirectional control action. Furthermore, the designs of current touch screens and touch panels are lack of feel and force feedback, that is, it is impossible to perform a feedback reaction action for the user's touch action. Therefore, there is an urgent need for a touch device that can perform a feedback response action to a user's touch action, so as to increase the user's operational feeling when operating the touch device.

Detailed ways

In order to make the above objects, features and advantages of the present invention more comprehensible, a preferred embodiment will be described in detail below together with the accompanying drawings.

FIG. 1 is a functional block diagram of a touch device 100 according to an embodiment of the invention. In one embodiment, the touch device 100 includes a touch unit 110 and a traverse unit 120 . The touch unit 110 is used for continuously detecting touch events and outputting corresponding touch signals. The touch unit 110 can be a touch panel (without a display screen) or a touch screen, which is used to detect the pressure, area pressure or touch applied by a touch object (such as a finger or a stylus) on the touch unit 110. The size of the control area is controlled, and the detected pressure or touch area is converted into a corresponding touch signal. For example, the touch unit 110 can be a pressure sensor, a light sensor, a capacitive sensor, an acoustic wave sensor or a heat sensor. The touch unit 110 in the following embodiments will be described by taking a capacitive sensor as an example. The traversing unit 120 makes the touch unit 110 (or the touch device 100 ) move in a traversing direction perpendicular to the touch direction according to the touch signal generated by the touch unit 110 , the details of which will be described later.

2A-2C are schematic diagrams of the movement of the touch unit 110 and the traverse unit 120 according to different embodiments of the present invention. When the touch unit 110 is realized by a capacitive sensor, the shape of the touch device 100 is mainly planar, as shown in FIG. 2A . However, the touch device 110 is not limited to a complete plane. For example, the touch device can be a curved surface (as shown in FIG. 2B and FIG. 2C ) or a cylinder. Furthermore, no matter what shape the touch unit 110 is, the moving direction of the touch unit 110 by the traverse unit 120 is when the touch object 200 (such as a finger or a stylus) touches the surface of the touch unit 110 a vertical direction.

In one embodiment, the touch signal generated by the touch unit 110 can be represented by a touch value. The touch value can represent the degree of pressure of the touch object on the touch unit 110 or its differential value (instantaneous change). For example, if the touch unit 110 is realized by a resistive sensor, the touch value is the magnitude of the pressure (voltage). If the touch unit 110 is realized by a capacitive sensor, the touch value is the capacitive area and the capacitive value, for example, the capacitive value of a single area or the capacitive area reaching a specific value. Those skilled in the field of the present invention can understand that the touch unit 110 implemented by using different types of sensors can sense various degrees of touch pressure.

3A-3D are schematic diagrams of a moving manner of a traverse unit according to an embodiment of the present invention. In one embodiment, the traverse device 120 may be disposed below or beside the touch unit 110 . Generally speaking, the traverse device 120 can be realized by using gears and linear motors, or other devices that can use electric power (or magnetic force generated by electric power) to move the touch unit 110 . For example, the movement of the touch unit 110 controlled by the traverse unit 120 may include single-axis one-way, single-axis two-way, two-axis one-way or two-axis two-way movement, which are shown in Figures 3A, 3B, 3C and Figure 3D shows. The above-mentioned one-way movement means that the touch unit 110 can only move forward along a single axis, and the above-mentioned two-way movement means that the touch unit 110 can move forward and backward about one axis. In addition, the movement mode of the touch unit 110 controlled by the traverse unit 120 includes a mechanism of automatically returning to the origin. In other words, the touch unit 110 has an initial position relative to the traverse unit 120 . Whenever the traverse unit 120 completes a movement corresponding to a touch value, for example, after 0.5 seconds, the traverse unit 120 will automatically return the touch unit 110 to the initial position. Furthermore, the traverse unit 120 may also include an elastic force unit (not shown), so as to pull the touch unit 110 back to the initial position when the force provided by the touch object disappears.

7A-7B are schematic diagrams illustrating operations of a touch device according to different embodiments of the present invention. In one embodiment, the touch device 100 is a notebook computer as an example, and the touch unit 110 is a touchpad with no vertical stroke (note: the vertical stroke means that the touchpad has micro-mechanical switches). For example, when a user's finger taps on the touch unit 110, when the touch value (such as resistance value or capacitance value) detected by the touch unit 110 is greater than a predetermined value, the traverse device immediately moves touch unit 110 . Although the touch panel does not have a vertical stroke, due to the movement of the traverse device 120, the user can feel that the touch unit 110 will move in a first direction of the user, so as to obtain a result similar to the vertical stroke, as shown in FIG. Figure 7A. In this case, the touch unit 110 can also output a touch signal of the left mouse button. When the touch value (such as resistance value or capacitance value) detected by the touch unit 110 is not greater than the predetermined value, the traverse unit 120 does not operate and the touch unit 110 does not output the touch signal of the left mouse button. . When the user lifts the finger, the touch value will decrease accordingly. When the touch value decreases to a certain level, the traverse unit 120 moves the touch unit 110 in a second direction opposite to the first direction.

In another embodiment, the touch device 100 is a mobile phone as an example. The user must use the touch object 700 (finger or stylus) to press the touch screen of the mobile phone (ie, the touch unit 110) to a specific force (ie, the touch value is greater than a predetermined value), and the traverse unit 120 will generate corresponding traverse action. At this time, the phone will unlock the screen according to this state. In other words, the user only needs to apply an appropriate force on the finger, and the traversing unit 120 will move the touch unit 110, so the user can directly feel the feedback information from the touch device 100, and know the mobile phone without looking at the screen. The screen of is unlocked, as shown in Figure 7B.

Different implementations of the touch method in the present invention will be introduced in the following embodiments. FIG. 4 is a flow chart of a touch method according to an embodiment of the invention. In step S400 , the touch unit 110 detects a touch value (such as pressure value, capacitance value, etc.) of a touch object on the touch unit 110 . In step S410, the traverse unit 120 determines whether the touch value detected by the touch unit 110 is greater than a predetermined value. If yes, the traverse unit 120 moves the touch unit 110 in a first direction by a first predetermined distance (step S420 ), so that the user can feel the feedback from the touch device 100 . If not, the traverse unit 120 does not operate (step S430). It should be noted that the first direction in which the touch unit 110 moves can be performed on a single axis (such as a single direction) or dual axes (such as an oblique line or a diagonal line) of the traverse unit 120 .

FIG. 5 is a flowchart of a touch control method according to another embodiment of the present invention. In step S500 , the touch unit 110 detects a touch value (such as pressure value, capacitance value, etc.) of a touch object on the touch unit 110 . In step S510, the traverse unit 120 determines whether the touch value detected by the touch unit 110 is greater than a predetermined value. If yes, the traversing unit 120 moves the touch unit 110 in a first direction by a first predetermined distance, and the touch unit 110 outputs a corresponding touch signal (such as pressing the left mouse button) (step S520), In order to let the user feel the feedback of the touch device 100 . If not, the traverse unit 120 does not operate, and the touch unit 110 does not output a touch signal (step S530 ).

FIG. 6 is a flow chart of a touch method according to another embodiment of the present invention. In step S600 , the touch unit 110 detects a touch value (such as pressure value, capacitance value, etc.) of a touch object on the touch unit 110 . In step S610, the traverse unit 120 determines whether the touch value detected by the touch unit 110 is greater than a predetermined value. If yes, the traversing unit 120 moves the touch unit 110 in a first direction by a first predetermined distance, and the touch unit 110 outputs a corresponding first touch signal (such as pressing the left mouse button (Touch Down) ) (step S620 ), so that the user can feel the feedback from the touch device 100 . If not, the traverse unit 120 does not operate, and the touch unit 110 does not output a touch signal (step S630 ). After step S620 is executed, the touch unit 110 will continue to detect whether the current touch value decreases (step S640 ). When the current touch value decreases, the traverse unit 120 moves the touch unit 110 by the first predetermined distance in a second direction opposite to the first direction (step S650 ). At this time, the touch unit 110 may also selectively output a corresponding second touch signal (for example, release the left mouse button (Touch Up)) (step S660 ). When the current touch value increases, it returns to step S610. It should be noted that the touch unit 110 in step S620 will deviate from its initial position after the first lateral movement, and the second lateral movement in step S650 adjusts the touch unit 110 back to its initial position.

Although the present invention is disclosed above with preferred embodiments, it is not intended to limit the scope of the present invention. Anyone skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, this The protection scope of the invention shall be determined by the protection scope of the claims.
