Description

Touchpad and input sensing method

The present invention relates to a touch pad and a method for detecting an input thereof, and more particularly, to realize a touch pad without a click button and to detect a case where two fingers are simultaneously touched or vice versa to activate or deactivate the mouse cursor on the screen. The present invention relates to a touch pad capable of executing a click button function by detecting a release of a left or right finger on a pad and a touch.

Means for inputting information to a computer include a keyboard and a mouse. In particular, a mouse moves a position of a cursor (or a pointer) displayed on a monitor screen, or executes a command at a specific position on the displayed screen. It is widely used as a convenient tool to do this.

Recently, netbooks, laptops, and tablets, which are important for portability, have become commonplace. Due to the convenience of these devices, touch pads can replace the functions of the mouse or trackball for the movement of the cursor (or pointer). It is mainly installed and released.

In general, a touch pad is a flat pointing device, which is configured to touch a surface with a finger, and may also be referred to as a track pad. The touch pad may be configured by using an input means such as a finger or a pen. Recognizing the action of touching the pad is used as a basic principle, so it is more natural and accurate to move the cursor or pointer than using a mouse, so that characters or figures can be entered accurately.

However, since the touch pad is configured to be used together with left and right click buttons for executing a function corresponding to a mouse key in the periphery thereof (particularly in the lower part), the touch pad and the left hand are used with one hand in using the touch pad. Because it is difficult to operate the right click button at the same time, it was inconvenient to use. Therefore, the user can operate the touch pad and the click button by using both hands or connect an external mouse separately, which causes secondary problems. Caused it.

In this regard, Korean Patent Laid-Open Publication No. 10-1999-015774 (published on March 5, 1999; hereinafter referred to as 'Patent Document 1') discloses a technology related to a touch pad and a method for implementing a mouse key function.

According to Patent Literature 1, a detection means for detecting a first coordinate value generated by being touched on the touch pad and a second coordinate value generated by being touched in a state where the first coordinate value is recognized, and detected by the detection means. Comparison means for comparing the first coordinate value and the second coordinate value, and if it is determined that the first coordinate value is large, the operation corresponding to the left button input of the mouse is performed, and the first coordinate value is smaller than the second coordinate value. If it is determined that a mouse key function is implemented with a control means to perform an operation corresponding to the right button input of the mouse, the touch pad is provided so that all the functions of a mouse can be performed on one pad without having a separate mouse key. It was made.

In addition, Korean Patent Application Publication No. 10-2007-0103626 (published on October 24, 2007; hereinafter abbreviated as 'Patent Document 2') controls input information of a touch pad that controls to process unclear input information that is touch-operated by the touch pad. A technique relating to a method and apparatus is disclosed.

According to Patent Literature 2, a touch pad for receiving a touch signal is provided, and a comparison unit for comparing whether the information input to the touch pad is included within a tolerance range of the reference information preset in the storage unit is provided. In the case of being within the tolerance range, the input information is performed. On the other hand, if it exceeds the tolerance, the information similar to the input information is extracted and provided from the storage unit. By selecting the information, the corresponding function is performed.

However, in the former case, in the former case, since the logic is configured to detect the second coordinate value generated by being touched on again when the first coordinate value generated by being touched on the touch pad is recognized, the first coordinate value and There was a disadvantage in that the temporal motion delay characteristic inevitably occurs due to the detection of the second coordinate value, and the drag gesture performed by one finger and the tracking gesture are the same, and it is unclear how the system switches back to tracking after the drag. There was a risk of falling into the infinite drag state.

In addition, in the latter case, since the information input to the touch pad is outside the allowable error range of the reference information, the information is similar to the input information extracted from the storage unit and configured to allow the user to selectively input the information. Not only were they lowered, but they also resulted in reduced convenience.

In the case of fish touchpads, two-button and multi-touch systems are already produced and sold by Logitech and Apple, which are the same as laptops, such as Logitech's touchpad (wireless or T650) or Apple's tracks. The pad requires a lot of movement of the hand or finger during operation, resulting in a lot of pressure on the finger or wrist.

Of course, the scroll unit provided separately detects a moving direction according to the movement of a finger or a pen by the pressure change of each electrode cell in the second touch area for scrolling and scrolls up and down at the cursor display position on the screen in the corresponding direction. The function can be executed.

8 to 11 are flowcharts illustrating an input sensing method of a touch pad according to another exemplary embodiment of the present invention. The input sensing method of the touch pad according to another exemplary embodiment of the present invention is not provided with a scroll unit. An input sensing method performed by a tracking unit, comprising: (b1) detecting a case where two points on a first touch area are simultaneously touched and activating a cursor on the screen (S201-S203), (b2) step (b1) Recognizing two touch points simultaneously detected through the touch point as the left touch point and the right touch point for tracking (S204) and (b3) each touch recognized in the first touch area through the step (b2). Step (S206, S207), and (b4) In the cursor activation state on the screen, if an on state is detected at three or more touch points by detecting the movement of the point, the left of the three touch points is detected. Recognizing one point as the scroll touch point for scrolling and recognizing the two right points as the left and right tracking touch points for tracking (S208, S209) and (b5) the first touch area through the step (b4). Detecting a movement direction with respect to the scroll touch point recognized by S1 and executing up / down scroll function at the cursor display position on the screen in the corresponding direction (S210, S211), and (b6) in the cursor activation state on the screen (b2 (B4) selectively detecting the off state of the left and right tracking touch points recognized in the first touch area through step (b4) and selectively processing the inactivation of the cursor on the screen or the execution of the left and right click function of the mouse key. It consists of (S212 ~ S226).

At this time, step (b6) is a step of (b61) detecting a simultaneous off state of two touch points recognized in the first touch area through the step (b2) or (b4) to deactivate the cursor on the screen (S212 to S218). , (b62) Detecting the off state of any one of the two touch points recognized in the first touch area through the step (b2) or (b4), respectively, to initiate the left click and end or right click function of the mouse key. Each of the steps (S219 to S223, S224 to S226) is performed.

Referring to the operation and effects of the touch pad and the input sensing method of the present invention configured as described above in detail as follows.

First, in operation of the touch pad 10 having the tracking unit 11 and the scroll unit 12, as illustrated in FIGS. 6 to 7, the tracking unit may be simultaneously located at two points on the first touch area. In operation S101, when it is detected that two touch points are simultaneously touched on the first touch area (Y branch of S101), the cursor on the screen is activated (S103), and at two points on the first touch area. If not touched on at the same time (N branch of S101), the cursor on the screen is deactivated (S102) and the deactivation state is displayed (for example, the cursor size or color is displayed differently) so that the user can recognize the deactivation state of the cursor. To be.

Subsequently, the tracking unit recognizes the two touch points simultaneously detected through the step (a1) as the left touch point and the right touch point for tracking, respectively (S104), and then each touch recognized through the step (a2). If the movement of the point is detected (S106), and if the movement of the touch point is detected (Y branch of S106), tracking according to the movement of any one of the touch points (which may be any one of the left and right touch points preset) The process is performed (S107).

In addition, the tracking unit detects an off state for each touch point detected through step (a1) in the cursor activation state on the screen, respectively (S108, S115, S120), and detects the off state of each touch point. When the simultaneous off state is detected (Y branch of S108), for example, the set first time counter T1 is activated (S109) to determine whether the user's intentional touch point is off (finger release operation), and thus the designated time. If the touch point off is maintained (Y branch of S110), the cursor on the screen is deactivated (S111). At this time, if any of the left or right touch points is detected before the set time of the specified first time counter T1 elapses (Y branch of S112 or Y branch of S113), the operation of the first time counter is stopped. After stopping, it initializes (S114) and returns to the touch point movement or off state detection step (S106).

On the other hand, when the off state detection result for each touch point is detected, the off state of any one of the two touch points (Y branch of S115 or Y branch of S120), that is, for example, for the left touch point of the two touch points When the OFF state is detected (Y branch of S115), first, it is determined whether or not the second set time (for example, 0.1 sec) has elapsed in order to determine whether or not the temporary contactless state is determined (S116) and the temporary contactless state. (Y branch of S116), the mouse key recognizes and processes the start of the left click, displays the state (S117), checks again whether the on state is detected with respect to the left touch point (S118), and ends the end of the left click. After recognizing and performing the corresponding process, the state is displayed (S119).

For example, when an off state is detected for the right touch point among two touch points (Y branch of S120), first, the second predetermined time (for example, 0.1 sec) is set to determine whether or not the temporary contact is not made. It is determined whether or not the temporary non-contact state (S121). If it is not a temporary non-contact state (Y branch of S121), the right-click of the mouse key is recognized and the right-click function is executed (S122). Of course, the scroll unit provided separately detects a moving direction according to the movement of a finger or a pen by the pressure change of each electrode cell in the second touch area for scrolling and scrolls up and down at the cursor display position on the screen in the corresponding direction. The function can be executed.

Next, referring to an operation of the touch pad including only the tracking unit without providing a scroll unit separately, as illustrated in FIGS. 8 to 11, the tracking unit determines whether the touch unit is simultaneously touched at two points on the first touch area (S201). When a case where touch on two points on the first touch area is detected simultaneously (Y branch of S201) is activated (S203), the cursor on the screen is activated (S203). N branch) of the screen inactivates the cursor (S202) and displays the deactivation state (for example, by changing the size or color of the cursor) so that the user can recognize the cursor deactivation state.

Subsequently, the tracking unit recognizes the two touch points detected simultaneously through the step (b1) as the left touch point and the right touch point for tracking, respectively (S204), and then each touch recognized through the step (b2). If the movement of the point is detected (S206), and if the movement of the touch point is detected (Y branch in S206), tracking according to the movement of any one of the touch points (which may be any one of the preset left and right touch points) is performed. The process is performed (S207).

In addition, the tracking unit (b4) checks whether the on-state is detected at three touch points or more from the first touch area in the cursor activation state on the screen (S208), and if the on-state is detected at three or more touch points (Y branch in S208). ), One left point of the three touch points is recognized as the scroll touch point for scrolling, and two right points are recognized as the left and right tracking touch points for tracking, respectively (S209).

Subsequently, the moving direction of the scroll touch point recognized in the first touch area is detected (S210) through step (b4), and the moving direction of the scroll touch point (eg, the leftmost touch point of the three touch points) is detected. Is detected (Y branch of S210), the up / down scroll function at the cursor display position on the screen in the corresponding direction is executed (S211).

In addition, the tracking unit detects an off state of the right two touch points among the three touch points detected through the step (b1) in the cursor activation state on the screen, respectively (S212, S219, S224), and turns off the two right touch points. As a result of the state detection, when a simultaneous off state of two touch points is detected (Y branch of S212), for example, the first time counter T1 set to determine whether the user intentionally touches off (releases finger) is operated. In operation S213, when the touch point off is maintained for a specified time (Y branch in S215), the cursor on the screen is deactivated (S214). At this time, if any of the left or right touch points is detected before the set time of the specified first time counter T1 elapses (Y branch of S216 or Y branch of S217), the operation of the first time counter is stopped. After stopping, it initializes (S218) and returns to the touch point movement or off state detection step (S206).

On the other hand, if the off state detection result for each of the two touch points on the right side, the off state of any one of the two touch points is detected (Y branch of S219 or Y branch of S224), that is, for example, for the right first touch point When the OFF state is detected (Y branch of S219), first, it is determined whether or not the set second designated time (for example, 0.1 sec) has elapsed in order to determine whether or not the temporary contactless state (S220) and determines whether it is a temporary contactless state (S220). If not (Y branch of S220), it recognizes and processes the start of the left click of the mouse key and displays the state (S221), and again checks whether the on-state detection for the left touch point (S222) to end the left click. After recognizing and performing the corresponding process, the state is displayed (S223).

For example, when an off state is detected for the right second touch point (Y branch of S224), first, a temporary non-contact is checked by checking whether the second designated time (for example, 0.1 sec) has elapsed to determine whether or not the temporary non-contact is made. If it is in the state of being in a non-contact state (Y branch of S225), it is recognized as a right-click of the mouse key, and the right-click function is executed (S226).

As a result, the present invention can improve the point that it was difficult to simultaneously control the existing touch pad and the click button with one hand, thereby providing convenience of a general mouse level.
