Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood that the embodiments described below are provided to fully convey the spirit of the present invention to a person having ordinary skill in the art to which the present invention belongs. The present invention may be embodied in other embodiments. For the sake of clarity of the present invention, the drawings may omit the parts of the drawings that are not related to the description, and the size of the elements and the like may be somewhat exaggerated to facilitate understanding.

FIG. 1 is a perspective view showing a second state of the touch input device 100 according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line A-A of FIG. 3 is a perspective view showing a first state of the touch input device 100 according to the first embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along line B-B of FIG.

The touch input device 100 according to the first embodiment of the present invention includes a touch block 101 installed on a mounting surface 130 and a touch block 101 connected to the touch block 101 to move up and down the touch block 101 Unit 102 as shown in FIG.

The touch block 101 may include a cylindrical body portion 111 and a touch portion 110 provided on the upper portion of the body portion 111. [ The touch unit 110 may be provided in a predetermined area for receiving a touch signal of a user. For example, the planar shape may be circular as shown in the figure. Or an elliptical shape.

The touch unit 110 may be a touch pad to which a signal is input when the user touches or approaches a pointer such as a finger or a touch pen. The user can input a predetermined touch gesture to the touch unit 110 and input a desired instruction or command.

The touch pad may include a touch film or a touch sheet including the touch sensor regardless of its name. In addition, the touch pad may include a touch panel which is a display device capable of touching the screen.

On the other hand, recognizing the position of the pointer in proximity with the pointer not touching the touch pad is referred to as " proximity touch ", and when the pointer touches the touch pad, touch ". At this time, the position to be the proximity touch may be a position where the pointer corresponds vertically to the touch pad when the pointer is close to the touch pad.

The touch pad may be a resistive type, an optical type, a capacitive type, an ultrasonic type, or a pressure type. That is, known various types of touch pads can be used.

The touch input apparatus 100 according to an embodiment of the present invention may include a frame 120 positioned between the mounting surface 130 and the touch block 101. That is, the touch block 101 may be installed inside the rim 120.

The rim portion 120 refers to a portion surrounding the periphery of the touch portion 110 when viewed on a plane, and may be provided as a separate member from the touch portion 110. [ The rim portion 120 may be integrally formed with the mounting surface 130 or may be a separate member provided between the mounting surface 130 and the touch portion 110. In addition, the rim portion 120 may be omitted. In this case, the touch portion 110 may be installed directly inside the mounting surface 130.

A key button or a touch button 121 surrounding the touch unit 110 may be positioned on the rim 120. That is, the user may input the gesture at the touch unit 110 or input the gesture using the button 121 provided at the edge 120 around the touch unit 110. [

The rim portion 120 may include a receiving groove 122 for receiving the cylindrical touch block 101. The touch block 101 is provided so as to be movable upward and downward in the receiving groove 122 of the rim 120. For example, the receiving groove 122 and the outer surface 112 of the touch block 101 may extend in the vertical direction.

In addition, the receiving groove 122 and the outer surface 112 of the touch block 101 may be provided close to each other. That is, the tolerance or the gap is set to be small so that foreign matter can be prevented from being caught between the receiving groove 122 and the touch block 101. Or a foreign matter preventing member may be inserted between the receiving groove 122 and the touch block 101 although not shown in the figure. Or a bearing may be inserted between the receiving groove 122 and the touch block 101 for smooth upward and downward movement of the touch block 101.

The driving unit 102 according to an embodiment may include a nut 141 connected to the touch block 101, a screw 142 coupled with the nut, and a motor 143 rotating the screw 142.

The nut 141 may be coupled to the lower portion of the body portion 111 of the touch block 101. Or the nut 141 may be integrally formed with the body portion 111. [ That is, the nut 141 may be formed in the form of a threaded boss formed on the inner circumferential surface of the groove recessed in the lower portion of the body portion 111. However, when the nut 141 and the body part 111 are provided as separate members, only the nut 141 can be replaced when the threaded part of the nut 141 is damaged, which is advantageous in terms of maintenance.

A thread engaging with the nut 141 is formed on the outer circumferential surface of the screw 142. The screw 142 is connected to the rotation shaft 144 of the motor 143 and rotates together. Although the screw 142 and the rotation shaft 144 of the motor 143 are directly connected to each other in the drawing, the motor 143 and the screw 142 may be connected to each other by a speed reducer.

Next, the operation of the drive unit 102 will be described.

The rotational motion of the screw 142 is converted into the translational movement of the nut 141. [ The motor 143 is fixed to one side, and the nut 141 is provided to prevent rotation. The touch block 101 can be prevented from rotating with the rim portion 120. [ A rotation preventing groove (not shown) formed to extend in the vertical direction in the receiving groove 122 of the rim portion 120 and a rotation preventing groove (not shown) formed to extend in the vertical direction on the outer surface 112 of the touch block 101 The protrusion (not shown) is combined to allow the touch block 101 to move up and down while preventing the touch block 101 from rotating.

The touch input apparatus 100 according to the first embodiment of the present invention may further include a wrist support means 131 positioned below the touch unit 110 and supporting a user's wrist. At this time, the supporting surface of the wrist support means 131 may be positioned higher than the touch surface of the touch portion 110. [ This can prevent the wrist from being bent upward when the user inputs the gesture to the touch unit 110 with the wrist supporting the wrist support means 131. Accordingly, it is possible to prevent the user from suffering from a stigmatizing disorder which may occur during the repeated touch input process, and to provide a more comfortable operation feeling.

For example, as shown in the drawing, the wrist support means 131 may be integrally formed with the mounting surface 130, and may be formed to protrude from the mounting surface 130. Or the wrist supporting means 131 may be a separate member provided on the mounting surface 130. [

The touch input apparatus 100 according to the first embodiment of the present invention may include a controller that recognizes a gesture signal input to the touch unit 110 and analyzes the gesture signal to issue commands to various devices. In addition, the control unit may transmit a signal for operating the drive unit 102 to switch the state of the touch input device 100. [

The touch input device 100 according to the first embodiment of the present invention has different positions of the touch blocks 101 in the first state and the second state. That is, the driving unit 102 can be operated to change the height of the touch block 101 by switching from the first state to the second state, or from the second state to the first state.

The first state is a state in which the touch input device 100 is activated and the touch part 110 receives a touch input and the second state is a state in which the touch input device 100 is inactivated, And the command can not be executed. For example, the first state may indicate a state in which the touch input apparatus 100 is powered on, and the second state may indicate a state in which the touch input apparatus 100 is powered off. Or both of the first state and the second state are in the power-on state, the second state is the state in which the lock function is activated and the touch portion 110 is not received or the command is not executed, Lt; / RTI >

The touch input device 100 according to the first embodiment of the present invention can perform the locking function. The locking function means to stop the user from receiving the input or to stop the execution of the command on the received signal. When the lock function is executed, the touch input device 100 does not respond to the user's operation. Therefore, even if the user touches the touch unit 110, the command is not executed.

The drawing does not show a configuration for switching the state of the touch input apparatus 100. [ However, the method for switching from the first state to the second state, or from the second state to the first state may be variously provided. For example, the state can be switched by operating a separate button or the like, and the state of the user can be recognized by recognizing the voice instruction of the user. When the touch input device 100 according to the first embodiment of the present invention is used in a vehicle, the power of the vehicle or the power of the AVN device is switched to the first state when the power is turned on, It may be switched to the second state.

When the touch input unit 100 is not turned off and the command corresponding to the input signal of the touch unit 110 is not executed even in the second state, a predetermined signal is input to the touch unit 110, And the second state.

5 is a plan view for explaining an operation of the touch input device 100 according to the first embodiment of the present invention.

The control unit may move a cursor or a menu on the display unit (not shown) according to the position at which the pointer moves on the touch unit 110. That is, when the pointer moves from the upper part to the lower part, the cursor displayed on the display part can be moved in the same direction, or the pre-selected menu can be moved from the upper menu to the lower menu.

In addition, the control unit may analyze the locus of movement of the pointer to correspond to the predefined gesture, and execute the command defined in the corresponding gesture. The gesture can be entered by flicking, rolling, spinning, or tapping the pointer. In addition, the user can input gestures using various touch input methods.

Here, the flicking is a touch input method in which the pointer moves in one direction in a state where the pointer is in contact with the touch portion 110, and then the contact state is released. Rolling is a touch input method in which an arc is drawn around the center of the touch portion 110 , A spin refers to a touch input method of drawing a circle around the center of the touch part 110, and a tap refers to a touch input method of tapping the touch part 110.

The user may also input a gesture using a multi-pointer input method. The multi-pointer input method refers to a method of inputting a gesture in a state in which two pointers are simultaneously or sequentially in contact with each other. For example, the user can input a gesture while touching two fingers on the touch unit 110. [ By using the multi-pointer input method, it is possible to provide various commands or instructions that the user can input.

Various touch input methods include inputting gestures such as numbers, letters, or symbols, as well as inputting any promised gestures. For example, the user can input a command by drawing the consonant / vowel, alphabet, Arabic numeral, or arithmetic operation symbol of Hangul in the touch unit 110 as it is. The user can directly input the letters or numbers to be input to the touch unit 110 instead of selecting them on the display unit, thereby shortening the input time and providing a more intuitive interface.

The touch unit 110 may be provided so as to be capable of a pressing operation or a tilting operation. The user may press a part of the touch part 110 by applying pressure to the touch part 110 and input an execution signal according to the pressing. Here, the pressing operation includes a case in which the touch portion 110 is pressed in parallel and a case in which the touch portion 110 is tilted in parallel. Also, when the touch part 110 is provided in a flexible manner, only a part of the touch part 110 can be pressed.

For example, the touch unit 110 may be inclined in at least one direction d1 to d4 with respect to a direction perpendicular to the touch surface. For example, as shown in Fig. 2, it can be inclined in the forward, backward, left and right directions d1 to d4. Of course, it may be arranged to be inclined in various directions according to the embodiment. In addition, when the center portion d5 of the touch portion 110 is pressed, the touch portion 110 can be pressed in a parallel state.

The user can press or tilt the touch input device 100 to input a predetermined instruction or command. For example, the user can press a center portion d5 of the touch unit 110 to select a menu or the like, and press the upper portion d1 of the touch unit 110 to move the cursor upward.

In addition, the touch input device 100 may further include a button input unit 121. The button input unit 121 may be located around the touch unit 110, and may be installed at the frame unit 120, for example. The user can operate the button 121 without moving the position of the hand while inputting the gesture, so that a quick operation command can be issued.

The button input means 121 includes a touch button and a physical button. A touch button is input by a touch of a pointer only, and a physical button is input by a change of shape due to a physical external force. The physical button may include, for example, a button that can be clicked and a button that can be tilted.

In the drawing, five buttons 121 (121a, 121b, 121c, 121d, 121e) are shown. For example, each button 121 includes a Home button 121a for moving to a Home menu, a Back button 121d for moving to a previous screen in the current screen, An option button 121e for moving, and two shortcut buttons 121b and 121c. The shortcut buttons 121b and 121c are designed so that a menu or a device frequently used by a user can be specified and moved immediately.

Although not shown in the drawing, the touch input device 100 may include various components related to the operation. The touch input device 100 may include a structure for allowing the touch unit 110 to be tilted or tilted in the above-described five directions d1 to d5. Although these structures are omitted and shown in the drawings, there is no difficulty in implementing them using techniques commonly used in the related art.

In addition, various semiconductor chips, a printed circuit board, and the like may be installed in the touch input device 100. On the other hand, the semiconductor chip may be mounted on a printed circuit board. A semiconductor chip can perform information processing or store data. The semiconductor chip analyzes the external force applied to the touch input apparatus 100, the gesture recognized by the touch unit 110, or a predetermined electrical signal generated according to the operation of the button 121 provided in the touch input apparatus 100 And generate a predetermined control signal according to the interpreted contents, and then transmit the control signal to the control unit, the display unit, or the like of another device.

Next, the touch input device 100-1 according to the second embodiment of the present invention will be described. 9 is a sectional view showing a second state of the touch input apparatus 100-1 according to the second embodiment of the present invention.

The touch portion 110-1 according to the second embodiment of the present invention may include a portion lower than a boundary between the rim portion 120 and the mounting surface 130. [ That is, the touch surface of the touch portion 110-1 may be positioned lower than the boundary line between the touch portion 110-1 and the rim portion 120. [ For example, the touch portion 110-1 may be inclined downward from a boundary line with the rim portion 120, or may be positioned with a boundary line between the rim portion 120 and the touch portion 110-1. For example, the touch portion 110-1 according to an embodiment of the present invention shown in FIG. 3 includes a curved portion including a concave curved surface.

The figure shows that the touch portion 110-1 is provided so as to be inclined downward continuously without a step at a boundary line with the rim portion 120. [ Alternatively, the touch portion 110-1 may be inclined downward at a boundary line with the rim 120 in a downward direction.

The touch portion 110-1 includes a portion lower than the boundary with the rim portion 120 so that the user can recognize the area and boundary of the touch portion 110-1 by touch. The recognition rate can be increased when the gesture is made in the central portion of the touch portion 110-1. Also, even if you enter a similar gesture, there is a risk of being recognized as a different command if you enter the gesture at different locations. The problem is that the user inputs a gesture without gazing at the touch area. If a user inputs a gesture while observing the display unit or inputs a gesture while concentrating on an external situation, the user can be advantageous in inputting the gesture in the correct position if the touch area and the boundary can be intuitively recognized by the touch . Therefore, the input accuracy of the gesture is improved.

The touch portion 110-1 may include a concave shape. Here, the concave shape means a recessed or recessed shape, and may include not only a rounded shape but also a shape that slopes or enters a stepped shape.

In addition, the touch portion 110-1 may include a concave curved surface shape. For example, the touch portion 110-1 according to the embodiment shown in the drawing is provided with a concave curved surface having a constant curvature. That is, the touch portion 110-1 may include some shape of the inner surface of the spherical surface. When the curvature of the touch unit 110-1 is constant, a foreign sense of operation can be minimized when the user inputs a gesture to the touch unit 110-1.

In addition, the touch portion 110-1 may include a concave shape, and may be formed so as to gradually become deeper or maintain the same depth from the outer portion to the central portion. That is, the touch portion 110-1 may be formed so as not to include a convex surface. If the touch portion 110-1 includes a convex surface, the trajectory of the user to draw a gesture naturally changes the curvature of the touch surface, which can be an obstacle to accurate touch input. The touch portion 110-1 shown in FIG. 1 is provided such that the center C1 is the deepest, and the touch portion 110-1 is lowered to a constant curvature from the outer portion toward the center C1.

On the other hand, the previously convex surface does not mean the convex point in the local area but the convex area in the entire touch area of the touch unit 110-1. Therefore, the touch part 110-1 according to the embodiment of the present invention may be formed as a small protrusion at the center so that the user can intuitively sense the position of the center part with a feeling that the protrusion can be felt, Shaped protruding portion such that the thin wrinkle protrudes.

Or the curved surface of the touch portion 110-1 may be provided with different curvatures. For example, the touch portion 110-1 may include a concave curved surface having a gentle slope toward the center portion. That is, the curvature of the region close to the central portion is small (meaning that the radius of curvature is large), and the curvature of the central portion and the far region, i.e., the outer portion, can be provided largely (meaning that the radius of curvature is small). By making the curvature of the central portion of the touch portion 110-1 smaller than the curvature of the outer portion, it is possible to easily input the gesture to the center portion by using the pointer. Since the curvature of the outer frame portion is larger than that of the central portion, the user can touch the outer frame portion to sense the curvature, so that the position of the center portion can be easily recognized even without looking at the touch portion 110-1.

The touch input device 100-1 according to the embodiment of the present invention includes a concave surface of the touch part 110-1, so that the touch feeling (or feeling of operation) felt by the user when the gesture is input can be increased. The curved surface of the touch portion 110-1 is similar to the trajectory drawn by the motion of the fingertip when the user moves the finger while holding the wrist, rotates the wrist with the finger, .

As in the embodiment of the present invention, the touch portion 110-1 including the concave curved surface is ergonomic as compared with the generally used flat touch portion. That is, the user's touch feeling is improved, and fatigue applied to the wrist, etc. can be reduced. And the input accuracy can be improved as compared with the case of inputting the gesture to the plane touch portion.

In addition, the touch portion 110-1 may be provided in a circular shape. When the touch portion 110-1 is provided in a circular shape, it is easy to form a concave curved surface. Also, since the touch part 110-1 is provided in a circular shape, the user can sense the circular touch area of the touch part 110-1 with a touch, so that it is possible to easily input the circular gesture operation such as rolling or spin.

In addition, since the touch portion 110-1 is provided with a concave curved surface, the user can intuitively know the position of the finger on the touch portion 110-1. Since the touch portion 110-1 is provided in a curved surface, the inclination of the touch portion 110-1 is changed at any point of the touch portion 110-1. Accordingly, the user can intuitively know the position of the finger on the touch unit 110-1 through the sense of inclination felt through the finger.

This feature is advantageous in that when a user inputs a gesture to the touch unit 110-1 while the user's eyes are fixed to the touch unit 110-1, By providing the feedback, the user can input the desired gesture, and the input accuracy of the gesture can be improved. For example, the user can intuitively know that the central portion of the touch unit 110-1 is touched when the tilt of the touch unit 110-1 transmitted to the finger is felt to be flat, 110 - 1, it is possible to intuitively know in which direction the finger is located.

On the other hand, the diameter and depth of the touch portion 110-1 can be determined in an ergonomic design range. For example, the diameter of the touch portion 110-1 may be selected within a range of 50 mm to 80 mm. Considering the average finger length of an adult, the range in which a finger can be moved at a time by movement of a natural finger while the wrist is fixed can be selected within 80 mm. If the diameter of the touch part 110-1 exceeds 80 mm, the movement of the hand becomes unnatural when the user draws a circle along the outer edge of the touch part 110-1, and the wrist is used more than necessary.

On the other hand, when the diameter of the touching part 110-1 is smaller than 50 mm, the area of the touching area is reduced and the variety of input gestures may be lost. Also, a gesture is drawn in a narrow area, which increases the input error of the gesture.

When the touch part 110-1 is provided in a spherical shape, the depth / diameter of the touch part 110-1 can be selected within the range of 0.04 to 0.1. The value obtained by dividing the depth of the touch portion 110-1 by the diameter means the degree of curving of the curved surface. That is, the larger the value of the depth / diameter in the touch portion 110-1 having the same diameter, the more concave the shape. On the other hand, the smaller the depth / diameter value, the more flat shape.

When the depth / diameter value of the touch portion 110-1 is larger than 0.1, the curvature of the concave shape becomes large, and the touch feeling of the user becomes inconvenient. It is preferable that the concave shape of the touch portion 110-1 coincides with the curvature of the curve drawn by the finger tip in the natural finger movement of the user. However, when the depth / diameter value exceeds 0.1, an artificial feeling is felt when the user moves the finger along the touch portion 110-1. When the user unconsciously and naturally moves the finger, the touch portion 110-1 and the finger tip may be separated from each other. In this case, the touch of the gesture is cut off and a recognition error occurs.

On the contrary, when the depth / diameter value of the touch unit 110-1 is smaller than 0.04, it is difficult for the user to feel the difference in the operation feeling as compared with the case where the user draws the gesture on the plane touch unit.

On the other hand, the touch pad used in the touch portion 110-1 provided on the curved surface can recognize the touch using the optical method. For example, an infrared LED (IR LED) and a photodiode array may be disposed on the rear surface of the touch unit 110-1. The infrared LED and the photodiode secure the infrared image reflected by the finger, and the control unit extracts the touch point from the secured image.

10 is a diagram showing a finger trace when a user inputs a gesture in the up and down direction to the touch unit 110-1 according to the second embodiment of the present invention. In the case where the gesture is inputted in the left-right direction on the touch portion 110-1 according to the second embodiment.

The touch portion 110-1 according to the embodiment of the present invention includes a concave curved surface. At this time, the curvature of the touching part 110-1 can be determined so that the user feels a sense of feeling when the user inputs a gesture. Referring to FIG. 4, a user can input a gesture only by natural movement of a finger in a state in which a joint does not move or break when a finger is moved up and down. Likewise, referring to FIG. 10, a user can input a gesture only by natural movement of a finger and a wrist in a state in which the user does not excessively twist his or her wrist when moving his or her finger to the left or right. Thus, the shape of the touch portion 110-1 is ergonomically designed so that fatigue that the user feels for a long time is small, and skeletal diseases that may occur in the wrist or other joints can be prevented.
