Touch device and touch method

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

Today's touch screens and touchpads are becoming more and more popular. For example, electronic devices such as desktop computers, notebook computers, smart phones or tablet computers use touch devices such as touch screens or touch panels. Take action. However, today's touch screens and touchpads are designed to operate directly on the surface of a touch object (such as a finger or a stylus). This is a one-way control action. Furthermore, today's touch screens and touchpads are designed with a lack of feel and force feedback, meaning that a feedback response action cannot be performed for the user's touch actions. Therefore, there is a need for a touch device that can perform a feedback reaction action on a user's touch action, thereby increasing the user's sense of operation when operating the touch device.

The present invention further provides a touch control method for a touch device, the touch device including a touch unit and a traverse unit. The method includes: utilizing The touch unit detects a touch value of a touch object on the touch unit; determining, by the traverse unit, whether the touch value is greater than a predetermined value; and when the touch value is greater than the predetermined value, utilizing The traverse unit moves the touch unit in a first direction by a first predetermined distance.

The above described objects, features and advantages of the present invention will become more apparent from the description of the appended claims.

1 is a functional block diagram of a touch device 100 in accordance with an embodiment of the present invention. In one embodiment, the touch device 100 includes a touch unit 110 and a traverse unit 120. The touch unit 110 is configured to continuously detect a touch event and output a corresponding touch signal. The touch unit 110 can be a touch panel (without a display screen) or a touch screen for detecting the pressure applied by the touch object (such as a finger or a stylus) on the touch unit 110. Or the size of the touch area, and convert the detected pressure or touch area into a corresponding touch signal. For example, the touch unit 110 can be a pressure sensor, a photo sensor, a capacitive sensor, an acoustic wave sensor, or a thermal sensor. The touch unit 110 in the embodiment will be described by taking a capacitive sensor as an example. The traverse unit 120 moves the touch unit 110 (or the touch device 100) in a traverse direction perpendicular to the touch direction according to the touch signal generated by the touch unit 110, and details thereof will be described later.

2A-2C are schematic diagrams showing the movement of the touch unit 110 in conjunction with the traverse unit 120 in accordance with various embodiments of the present invention. When the touch unit 110 is implemented by a capacitive sensor, the shape of the touch device 100 is mainly a plane. Shape, for example, shown in Figure 2A. However, the touch device 110 is not limited to a completely flat surface. For example, the touch device can be a curved surface (as shown in FIGS. 2B and 2C) or a cylindrical shape. Further, regardless of the shape of the touch unit 110, the traverse unit 120 moves the touch unit 110 to the surface of the touch unit 110 (for example, a finger or a stylus). a vertical direction.

In an embodiment, the touch signal generated by the touch unit 110 can be represented by a touch value. The touch value can indicate the degree of touch of the touch object on the touch unit 110 or its differential value (instantaneous change amount). For example, if the touch unit 110 is implemented by a resistive sensor, the touch value is the magnitude of the pressure (voltage). If the touch unit 110 is implemented by a capacitive sensor, the touch value is the size of the capacitor area and the capacitance value, such as the capacitance value of a single area or the capacitance area reaching a specific value. Those skilled in the art will appreciate that touch unit 110 implemented with different types of sensors can sense the degree of touch of various sizes.

3A to 3D are views showing a movement mode of the traverse unit according to an embodiment of the present invention. In an embodiment, the traverse device 120 can be disposed below or to the side of the touch unit 110. In general, the traverse device 120 can be implemented using gears and linear motors, or other devices that can utilize power (or magnetic force generated by electrical power) to move the touch unit 110. For example, the traverse unit 120 controls the movement of the touch unit 110 to include a single-axis unidirectional, single-axis bidirectional, biaxial unidirectional or biaxial bidirectional movement, such as 3A, 3B, 3C, and 3D, respectively. Shown. The one-way movement mode means that the touch unit 110 can only move in the direction of a single axis, and the two-way movement mode means that the touch unit 110 can be forward and reverse for one axis. mobile. In addition, the movement mode of the touch unit 110 controlled by the traverse unit 120 includes a mechanism for 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 the movement corresponding to a touch value, for example, after 0.5 seconds, the traverse unit 120 automatically returns the touch unit 110 to the initial position. Furthermore, the traverse unit 120 can also include an elastic unit (not shown) to pull the touch unit 110 back to the initial position at the moment when the force provided by the touch object disappears.

7A-7B are schematic diagrams showing the operation of the touch device in accordance with various embodiments of the present invention. In one embodiment, the touch device 100 is exemplified by a notebook computer, and the touch unit 110 has a touch panel having no longitudinal stroke (note: the longitudinal stroke indicates that the touch panel has a micro-motion switch). For example, when a user's finger taps on the touch unit 110, when the touch value (for example, the resistance value or the capacitance value) detected by the touch unit 110 is greater than a predetermined value, the traverse device immediately The touch unit 110 is moved. Although the touchpad has no longitudinal travel, because of the action of the traverse device 120, the user can feel that the touch unit 110 moves to a first direction of the user, thereby obtaining a result similar to the longitudinal stroke, such as Figure 7A shows. In this case, the touch unit 110 can also output a touch signal of the left mouse button. When the touch value (for example, the resistance value or the 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 of the left mouse button. Control signal. When the user lifts the finger, the touch value also decreases. When the touch value is reduced to a certain extent, 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 exemplified by a mobile phone. The user must use the touch object 700 (finger or stylus) to press a specific velocity on the touch screen of the mobile phone (ie, the touch unit 110) (ie, the touch value is greater than a predetermined value), and the traverse unit 120 A corresponding horizontal movement will be produced. At this point, the phone will unlock the screen based on this status. In other words, the user only needs to apply an appropriate force to the finger, and the traverse unit 120 moves the touch unit 110. Therefore, the user can directly feel the feedback information from the touch device 100, and the mobile phone can be known without watching the screen. The screen has been unlocked as shown in Figure 7B.

Different embodiments of the touch method in the present invention will be described in the following embodiments. 4 is a flow chart showing a touch method according to an embodiment of the present invention. In step S400, the touch unit 110 detects a touch value (eg, a pressure value, a capacitance value, etc.) of the 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 so, the traverse unit 120 moves the touch unit 110 in a first direction by a first predetermined distance (step S420), so that the user feels the feedback of 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 may be performed on a single axis (for example, a single direction) of the traverse unit 120 or a double axis (for example, a diagonal line or a diagonal line).

FIG. 5 is a flow chart showing a touch method according to another embodiment of the present invention. In step S500, the touch unit 110 detects a touch value (such as a pressure value, a capacitance value, and the like) of the 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 traverse unit 120 will touch the touch list The element 110 moves a first predetermined distance in a first direction, and the touch unit 110 outputs a corresponding touch signal (for example, pressing a left mouse button) (step S520), so that the user feels the touch device 100. Give feedback. If not, the traverse unit 120 does not operate, and the touch unit 110 does not output a touch signal (step S530).

Figure 6 is a flow chart showing a touch method according to still another embodiment of the present invention. In step S600, the touch unit 110 detects a touch value (eg, a pressure value, a capacitance value, etc.) of the 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 the traverse unit 120 moves the touch unit 110 in a first direction by a first predetermined distance, the touch unit 110 outputs a corresponding first touch signal (for example, pressing the left button (Touch Down). (Step S620), so that the user feels 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 S630). After the step S620 is performed, the touch unit 110 further continuously detects whether the current touch value is reduced (step S640). When the current touch value is decreased, the traverse unit 120 moves the touch unit 110 in the second direction opposite to the first direction by the first predetermined distance (step S650). At this time, the touch unit 110 can selectively output a corresponding second touch signal (for example, release the mouse up (Touch Up)) (step S660). When the current touch value is increased, 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 horizontal movement, and the second horizontal movement in step S650 adjusts the touch unit 110 by a reverse traverse. Go back to its original position.
