Description

A device and system that provides a distinction of buttons for various button configurations when a touch screen is operated using a vibrating touch screen {APARATUS AND SYSTEM FOR PROVIDING SENSE OF DIFFERENCE TO VARIOUS Configuration OF BUTTONS BY USING TOUCHSCREEN }

A device and method related to a touch screen giving a touch feeling.

In conventional mobile devices, by touching a physical device type provided by an input means such as a keypad or a click wheel, the user can easily recognize the touch by recognizing the distinction of which button is pressed or where the input means are located. there was.

However, as the size of the display area increases and the touch screen takes the place of an input button such as a keypad, the user cannot distinguish which button of the buttons output to the display device is pressed by the change of the input means. Information about the current contact location is also not passed to the user through any means other than visual feedback.

In order to overcome some of these problems, current mobile devices use a method of providing feedback through vibration of a single vibrator existing in the device when the user selects a button, but it only indicates that the button is selected, but which button is selected. It is not appropriate to provide information about whether or not the contact is made or to indicate the location of contact.

For this reason, the user is inconvenient to perform a task while looking at the screen when selecting a button, and by outputting the button to the screen, it is possible to use a button arrangement of various configurations and convenient replacement of other input means (such as a click wheel). This causes a decrease in the usefulness of the touch screen input method.

Accordingly, an object of the present invention is to combine a plurality of ultra-small vibrator on the touch screen in the mobile device that is used as an input means for recognizing the selection of the button by using a touch screen, such as a picture of the button or drag button, click wheel is output to the display device By providing the distinction between buttons according to the type of buttons currently used, or in the case of a click wheel, it is possible to recognize the touch through the touch, and by changing the software, it is possible to provide appropriate distinction for the buttons of various configurations. The purpose of the present invention is to maximize flexibility to provide various keypads (button arrays) / input means that support a clear distinction in the form of input means such as a button or a click wheel in a mobile device.

The prior art associated with the present invention is the haptic feedback function presented in US Patent Publication No. 2006-0119589 by Rosenberg et al. In the feedback device described herein, at least one actuator is coupled to the touch input device and outputs a force to provide a haptic response to the user in contact with the touch surface. At this time, the actuator is configured to use the touch panel installed in the suspension and the one configured to output haptic feedback to the suspension that amplifies the haptic feedback.

Unlike the present invention, the output of the haptic feedback is not transmitted to the touch panel or the suspension, but directly to an object used for contact of the user's finger or stylus pen. The difference is that they are exposed above the screen. In addition, the user can feel the boundary and appearance of the structure such as a button and a click wheel through a combination of a plurality of vibrators rather than recognizing that the button is selected through the vibrator. In this case, the purpose of the present invention is to provide the user with a sense of distinction between buttons by embodying the appearance as if it is a braille. The purpose is different so that the user can feel through the arrangement.

The present invention is to solve the above problems, in the case of a touch mobile device that does not exist, such as a keypad or a click wheel having a touch function, and replaces it with a touch screen, a button picture is displayed on the display screen. By pressing this, the touch screen recognizes the touch screen and replaces the button input.The user does not know which button is pressed or touched when moving between the buttons when the button is pressed and the recognition object such as a finger is touched on the screen. The disadvantage is that you need to identify the report button.

According to the present invention, the micro-vibrator is combined with the touch screen in a lattice form, and when the user touches a designated position according to the currently used button type, the user generates a sense of distinction of the button by operating the vibrator included in the corresponding area. Give feedback. This eliminates the inconvenience of having to watch the screen when the buttons are displayed on the screen by allowing the touch mobile device to distinguish the buttons that the user is currently touching or to recognize the location of the current contact without the user looking at the screen. In addition, the screen has a variety of button configuration and a touch and distinction similar to the actual touch of the input device, such as a click wheel, so as to use a variety of different button configuration as shown in the two examples (105) of FIG. It is to be able to.

In addition, in the present invention, a miniature vibrator is used as an example to convey a sense of distinction to the user, which is another method for allowing the user to recognize a disorder, for example, a method of flowing a current for a short time using a minute current, or a person. It can also be applied to structures, such as micro pushbuttons, that can exert a pressure slightly higher than this level.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

6 is a circuit diagram of a display device with a touch screen according to an embodiment.

The display device comprises a commercially available mobile device 602 including a CPU, RAM and NVRAM storage, and a communication module, a touchscreen / vibrator array complex 601 comprising a demultiplexer 603 connected to a control and column address lines and row address lines. And a data / power line, an oscillator array power line connected with the control unit 602. The touch screen / vibrator array composite 601 combines microminiature vibrators in a lattice form.

The touch screen / vibrator array composite 601 is described in detail in FIGS. 1,2 and 3.

1 shows a back view of a touch screen that includes an oscillator array composite 601. 2 shows a side view of the vibrator array composite 601. 3 illustrates a structure of a transfer element disposed in a lattice form in a touch pad and a conductive line connected to the transfer element.

The portable terminal 101 includes a touch screen 102. Each of the touch screens 102 includes a micro transfer element 103 in a lattice form, and the distance between the transfer elements 103 is constant, such as 104. In addition, the spacing between each transfer element 103 may be the width or multiples of the width of the display panel pixel 205.

Each transfer element 103 is preferably small enough to be located at the junction of the pixels so as not to interfere with the light emission from the pixels. Of course, the size of the forwarder used at this time is small enough to not affect the pixels. At this time, the transmission element 103 used here includes devices capable of giving feedback to the user, including the micro oscillator. The use of a miniature vibrator as the transmission element 103 is an example, and an electrode or the like capable of flowing a fine current may be used. Hereinafter, the vibrator will be described as an example.

Each vibrator 201 can be combined with a toggle switch 202 to turn it on / off. Each toggle switch is connected to a power line and a control line 203 for receiving an on / off signal. And all of these are implemented in combination with the touch screen film 204 as shown in the cross-sectional view of FIG.

In the case of using the FTIR-type multi-touch screen, since the 204 does not need to be a touch screen, the 204 may be combined with a general film and attached to the touch surface.

The toggle switch 202 turns on / off the power supply to the vibrator and changes its state to on / off every time a signal is applied to permit the supply of power to the vibrator when it is on. The oscillator is operated, and when it is off, the power is cut off to stop the operation of the vibrator.

Control signals for controlling these toggle switches are transmitted from the device via a row / column address line connected to the mobile device 602 of FIG. 6, which signal row / column demultiplexer 603. The translation into the row address 305 and column address 304 of FIG. 3 allows the desired oscillator 306 to be selected to toggle the switch.

Hereinafter, a method of selecting a desired vibrator will be described.

FIG. 4A illustrates a transmitting element to vibrate on a touch pad, and FIG. 4B illustrates a vibration map in which a transmitting element to vibrate is set.

First, the vibrators allowed to vibrate in the present situation correspond to the bit 404 set in the vibration map 403. Therefore, if only the vibrators 401 to 5C to 5L are allowed to operate as shown in the figure, the vibration map (hereinafter referred to as bitmap) is also set to only 404 to 5L bits. The bitmap is composed of the remaining bits, that is, bits except 5C to 5L, in an unset or clear state.

When the vibrators allowed to operate by the bitmap touch the surface of the touch screen through the finger 301 (or a stylus pen and the like) as shown in FIG. 3, the user touches a certain position through the touch screen ( 302) it can be found out. This information contains information about an arbitrary region, not a single point, and among the vibrators included in this region, only the vibrators allowed to operate by the bitmap are subjected to the vibrating operation (303).

In order to minimize the vibrator covering the information displayed on the touch screen, each transmission element such as the vibrator is connected to a grid for controlling the operation as shown in the right side of FIG. Through fabrication, individual transmission elements can be controlled.

In the case of controlling each transfer element using a separate controller, when the information of the bitmap 403 is set, the main control controller 602 uses this information to select the individual controller 307 corresponding to the position where the bit of the bitmap is set. The desired delivery element can be operated in an operating manner.

The individual controllers have two status information: switch on and off, and when the state is set on the main controller, it remains in that state until it is changed again, either sustaining the power supply or disconnecting the carrier from the power supply.

In the case of adopting the structure of FIG. 6 without a separate controller, only the transfer element of 306, which is a position intersected by applying power through the crossbars 304 and 305 of FIG. 3, is controlled to operate, which is a row / out of 602. By applying a column address. The part connected to the crossbar should be powered directly on the device so that only 1 is applied in the row / column, so that the power is connected and the transfer device operates.

In order to generate a vibration motion according to the vibration bitmap of the structure as shown in FIG. 7 or 8 using the crossbar, a plurality of vibrators existing at a position pressed by a user (such as a finger pressed) are formed in groups. It is operated by applying power by scheduling repeatedly in sequence.

9 and 10 are one embodiment of such an operation. In the following, signal and power supply are handled identically.

When all the vibrators placed on the same line as shown in FIG. 9 are activated together, signals are applied as shown in the figure, and temporal scheduling of the applied signals is not necessary.

However, when activation is required only in some cases as shown in FIG. 10, since the crossbar method is used, it is impossible to realize it unless it is divided in time. Therefore, the region is divided over several parts and the vibration signal is applied by distributing it on the time axis. Do it.

Various methods can be used as a division method, and four methods will be described below.

In a first method, each of the transfer elements can be operated individually one by one so that all activated transfer elements can be operated by supplying power in a round robin manner for a short time.

In the second method, power may be supplied in a weighted scheduling method through information on a touch screen. In the weight-based scheduling scheme, the pressure difference when the user touches the touch screen is sensed, and the transmission element belonging to the place pressed by the stronger pressure is assigned a weight to be assigned a longer operation time by setting the priority higher. In addition, various time division process scheduling schemes used in the computer OS may be applied thereto.

As a method of calculating the weight, there may be a method of calculating a higher weight where the size of the area is wider, based on the size of the area for the area pressed by the user including each transfer element.

As another weighting method, there is a method of considering the relationship between the pressure and the area of the area pressed by the user. For example, the value of the weight may be determined by Equation 1 as follows.

Here, the values of A and B may be predetermined or may be arbitrarily designated by the user through sensitivity setting.

In the third method, power is applied to all of the lines that need vibration in the line by line based on the row or column line. In FIG. 10, signals are sequentially given to four pairs in the order of (A-2,3,4), (B-1,4), (C-1,4), and (D-1, 1,2,3,4). It means to apply.

The fourth method is to assess whether the groups used in the second method can be merged, and if this is possible, combine and reduce the number of groups used in the round robin as much as possible. At this time, since the power is once applied, it may be applied again when it is circulated once, so that the time required for the operation of one transfer element is increased by finding and combining a combination that can be combined. For example, in FIG. 10, two pairs of (A, D-2, 3, 4) and (B, C, D-1, 4) are provided.

When controlling the operation of the transfer element by scheduling, the period of one cycle and the operation time of each element can be flexibly adjusted so that the user can feel well.

In addition, by specifying a variety of shapes and vibration patterns of each transfer element as an important function, it is possible to present a variety of distinction through a variety of vibration patterns during the group vibration.

In the above method, the purpose was to group each vibrator so that the user could not feel the vibrations in order as much as possible. However, the vibration time of the vibrator and the combination of the individual vibration patterns of each vibrator were long enough to allow the user to feel the difference in the vibration time. Through this, you can feel various vibration patterns as a whole.

For example, in FIG. 10, (B-1), (C-1), (D-1), (D-2), (D-3), (D-4), (C-4), The clockwise operation of (B-4), (A-4), (A-3), and (A-2) and the reverse operation thereof can be differentiated to give a different feeling.

5 is a flowchart showing the whole process of vibration control.

When the user touches the touch screen or the contact is dropped, the operation operates differently, and when the user starts the touch, the touch screen detects this (step 501). Then, it is determined whether or not the contact has started (step 502).

When the touch is started, information on the vibrator included in the area touched by the user is collected (step 503). This information is combined with the licensed vibrator position information of the vibration bitmap for discrimination supply used in the current input mode to obtain the position information of the vibrators included in the area touched by the user.

In this case, if scheduling is required due to a combination that cannot be turned on at once, one or more groups are created and ordered through a combination of transfer elements. Then, in the case of a stimulus transmission pattern of each transmission element, for example, a vibrator, a preset vibration pattern is used or a new vibration pattern is set, and then the vibrations are switched on to generate vibrations.

If the detected change of the touch screen detects that the touch is terminated by removing the contact, the position information of the vibrators included in the region where the user has previously touched and released the contact is also obtained. The oscillator stops the vibration by searching all the vibrators included in the released area from the list of currently switched on vibrators and turning off all the vibrators belonging to the released area. .

By repeating these processes, if the user touches the vibrators enabled in the vibration map, the separators between the buttons, which were originally set in the vibration map through the vibrations of the vibrators, or the position of a specific symbol or button boundary area, etc. It can be seen.

If the user's touch is not distinguished from the start or end of the touch by the characteristics of the used touch screen and is recognized only as a simple event occurrence, or after the touch has occurred, the touched state is not terminated. If it persists, the operation of the vibrator in operation is to be stopped after a certain time. At this time, the predetermined time may be set by the user's selection. Alternatively, the above predetermined time may be predetermined according to the device.

As an exemplary embodiment of the present invention, when the click wheel is displayed and used as shown in FIG. 7, only a corresponding region is provided when the user touches the vibrators existing at the position where the boundary of the click wheel and the boundary and protrusion of each button and the input structure are to be displayed. By switching on, the map can be created and used in a manner that notifies the presence of the boundary by vibrating, similar to the change in the feel at the boundary.

8 Similarly, since the division between each number in the numeric / character keypad is difficult except for the naked eye, the division line between the number buttons is set in a map, and when the user touches the division line, the user generates vibration in the corresponding part. Lets the user know that he has touched the button border.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential features.

Therefore, the embodiments described above are to be understood in all respects as illustrative and not restrictive, and the scope of the present invention is indicated by the following claims rather than the above description, and the meaning and scope of the claims And all changes or modifications derived from the equivalent concept should be interpreted as being included in the scope of the present invention.
