Description

Command input device using touch panel display}

The present invention relates to a command input device using a touch panel display, and more particularly, to a command input device suitable for an onboard navigation device.

A conventional navigation device will be described with reference to FIG. Data output from the direction sensor 901 and data output from the distance sensor 902 are supplied to the CPU 904 through the input interface 903. The CPU 904 obtains the direction of the vehicle, the travel route, and the like based on these data. Moreover, absolute position information obtained at the GPS receiver 906 and map data stored in the DVD-ROM 907 are supplied to the CPU 904 via the communication interface 905. In accordance with the program stored in the program ROM 904b, the CPU 904 appropriately uses the RAM 904a to calculate the current position of the vehicle based on the various data described above.

In addition, according to the program stored in the program ROM 904b, the CPU 904 uses the program stored in the program ROM 904b, the map data read out from the DVD-ROM 907, and the touch panel display through the motion detection unit 910. RAM 904a for controlling the image processing processor 908 and the touch panel display 909 to display a map and the position of the vehicle based on the current position of the vehicle calculated according to the user's command input from 909. Use it properly. The motion detector 910 detects whether a finger is in contact with the touch panel display 909 and also detects coordinates of the contact position.

In FIG. 10, an example of an image displayed on the touch panel display 909 is shown. As shown in FIG. 10, operation buttons 1002, 1003, 1004 are displayed on screen 1001 of touch panel display 909. The operation buttons 1002, 1003, 1004 are assigned to predetermined commands, respectively, and the user inputs a desired command by releasing his or her finger to contact one of these operation buttons.

Hereinafter, with reference to the flowchart of FIG. 11, the process performed by CPU 904 with respect to a user's command input is demonstrated in detail. First, the CPU 904 determines whether the finger is in contact with the touch panel display 909 based on the output from the motion detection unit 910 (S1101), and if the finger is touching, detects the coordinates of the contact position. (S1102). Next, a command corresponding to the coordinate is determined (S1103), and an operation (for example, zooming in the map) related to the determined command is determined (S1104). Then, control for executing the selected operation is executed (S1105).

In addition to the above-described method of inputting a command by pressing an operation button, there is also a conventional method of inputting a desired command by sliding a finger on a display screen of a touch panel display (for example, Japanese Unexamined Patent Publication). Nos. 11-85398, 10-141974, and 11-102274.

However, when a command is input by using an operation button displayed on the touch panel display, it is required for a driver who is a user to visually check the display screen of the touch panel display to check the position of the operation button corresponding to the desired command. . Therefore, entering a command during operation is very dangerous. Moreover, if the moving vehicle rattles, there is a possibility that the operation button is pressed incorrectly.

Moreover, even if the finger slides on the display screen of the touch panel display, there are some limitations regarding, for example, the starting or ending position of the finger sliding, so that entering a desired command without looking at the display screen of the touch panel display at all is required. it's difficult. Moreover, if the moving vehicle rattles, there is a possibility that the wrong route will be tracked.

SUMMARY OF THE INVENTION The present invention is made to solve the above-mentioned conventional problem, and its object is that when the driver inputs a command while driving, the driver does not need to look at the touch panel display, and even if the vehicle vibrates, the command is It is to provide a command input device that can be correctly input.

Through this configuration, since a command can be input based on the period of time during which the finger or pen makes contact with the touch panel display, the number of contacts, and the time interval between the contacts, this makes it possible to input various commands without visual inspection.

Further, in the command input device using the touch panel display of the present invention, the determination result obtained from the input determination means is not influenced by the contact position of the finger or the pen on the touch panel display.

With this configuration, the user can input a command by placing a finger at an arbitrary position on the touch panel display, and thus can easily enter the command without looking at the touch panel display at all.

Further, the command input device using the touch panel display of the present invention is determined by input determining means based on detection results obtained from the contact time detecting means, the contact number detecting means, and the contact interval detecting means and the detection result.

Further, the command input device using the touch panel display of the present invention has operation setting means for arbitrarily setting a coupling relationship between the input command determined by the input determining means and the control command determined by the operation selecting means based on the input command. It includes more.

This configuration allows the user to assign any operation to a predetermined command.

The time interval between the contact of the finger or the pen determined by chattering by the malfunction preventing means is changed based on the detection result obtained by the vibration detecting means.

Through this configuration, the time interval between the contacts determined by chattering is changed based on the vibration of the vehicle. For example, when stopped, the time interval between the contacts determined by chattering is short and the gravel road is driven. In the meantime, the time interval between the contacts determined by chattering becomes long, which enables an optimal chattering prevention process in accordance with the state of the vehicle.

Further, in the command input device using the touch panel display of the present invention, the contact time detecting means distinguishes between two or more states according to the length of time of the subsequent contact.

With this configuration, the commands can be distinguished based on the length of time of the subsequent contact, thus making the inputted command more diverse.

Further, in the command input device using the touch panel display of the present invention, the contact time detecting means can arbitrarily set the length at which the duration of the subsequent contact is distinguished.

With this configuration, the user can arbitrarily set the threshold for determining the contact period, so that the user can execute the input operation in accordance with his or her sense.

Further, in the command input device using the touch panel display of the present invention, the contact section detecting means can arbitrarily set the end time set for the command input.

With this arrangement, the waiting period consuming until the end of the command input can be adjusted to satisfy the needs of the user.

(First embodiment)

The structure of the command input device according to the first embodiment of the present invention is shown in FIG.

In FIG. 1, the command input device includes a touch panel display 100; Contact time detection means 101 for detecting a period during which the finger (or pen; omitted later) is in continuous contact with the touch panel display 100; Contact number detecting means (102) for detecting the number of times a finger touches the touch panel display (100); Contact interval detecting means (103) for detecting a period between when the finger is moved away from the touch panel display (100) and when the finger is then brought into contact; Input determination means 104 for determining an input command based on detection results obtained from the contact time detecting means 101, the contact number detecting means 102, and the contact interval detecting means 103; Among the predetermined operations, operation selecting means 105 for selecting an operation related to the input command based on the input command determined by the input determining means 104; Operation control means 106 for executing an operation selected by the operation selection means 105; Input for arbitrarily setting the coupling relationship between the detection results obtained by the contact time detecting means 101, the contact number detecting means 102, and the contact interval detecting means 103 and the input command determined by the input determining means 104. Combination setting means (107); and operation setting means (108) for arbitrarily setting a coupling relationship between the input command determined by the input determining means (104) and the operation selected by the operation selecting means (105).

The operation of the command input device of this embodiment configured as described above will be described.

A signal indicating whether a finger is in contact with the display screen is supplied from the touch panel display 100 to the contact time detecting means 101, the contact number detecting means 102 and the contact interval detecting means 103, respectively. Generally used touch panel displays have the function of outputting the coordinates of the contact position of the finger, but this function is not particularly required in the present invention. However, a touch panel display having such a function may be used.

The contact time detecting means 101 detects a period during which a finger contacts the touch panel display 100 based on a signal from the touch panel display 100. The period corresponds to, for example, T (1), T (2) or T (3), as shown in FIG. FIG. 2 shows a time sequence with a finger touching the touch panel display 100 three times.

The contact number detecting unit 102 detects the number of times a finger touches the touch panel display 100 based on a signal from the touch panel display 100. The number of times corresponds to N, for example, as shown in FIG.

Based on the signal from the touch panel display 100, the contact interval detecting means 103 detects a period between when the finger is moved away from the touch panel display 100 and when the finger comes in contact thereafter. The period corresponds to, for example, I (1), I (2) or I (3), as shown in FIG.

The input determination means 104 is a detection result obtained by the contact time detecting means 101, the contact number detecting means 102 and the contact interval detecting means 103, for example, based on the pre-arranged table shown in FIG. Determine the command accordingly. In Fig. 3, the periods T (1), T (2), T (3), ... detected by the contact time detection means 101 and the period I (detected by the contact interval detection means 103). 1), I (2), I (3), ...) are represented as "long" or "short". That is, in the example of FIG. 3, if the period detected by the contact time detecting means 101 or the contact interval detecting means 103 is longer than a predetermined threshold (for example, 1 second), it is indicated as "long". , Shorter, "short" is displayed. In this embodiment, although the period detected by the contact time detecting means 101 or the contact interval detecting means 103 is evaluated as being longer or shorter than a predetermined threshold, the present invention is not limited thereto, and the detected period is Two thresholds can be used to divide the three into three, i.e., "short", "medium", "long", etc. for evaluation. In addition, the threshold can be set and changed by the user.

The operation of the input determination means 104 will be described in more detail. When the user presses the touch panel display 100 in a "short-tap" or "short-tap" manner with a finger, the input determining means 104 determines that the user, based on the table shown in FIG. It is determined that the command input by the command is command A. When the user presses the touch panel display 100 with a finger in a "short-tap", pause, "short-tap" manner, the input determining means 104 determines that the command input by the user is the command B. Decide In addition, when the user presses the touch panel display 100 with a finger in a "short-tap", "short-tap", and "short-tap" manner, the input determining means 104 is based on the table shown in FIG. Thus, it is determined that the command input by the user is command C. When the user presses the touch panel display 100 with a finger in a "short-tap", "short-tap", "long-tap" manner, the input determining means 104 determines that the command input by the user is the command E. Decide on that.

The command input device of the present invention is provided with an input combination setting means 107 for arbitrarily setting the table shown in FIG. Therefore, the user can set the combination of the period of time during which the finger is in contact with the touch panel display 100, the number of touches and the time interval between the touches.

The operation selecting means 105 selects an operation corresponding to the determination result obtained from the input determination means 104, for example, based on the pre-sorted table shown in FIG. More specifically, when the determination result obtained from the input determination means 104 is the command A, "starting the route guidance" is determined based on the table shown in Table 4. When the determination result obtained from the input determination means 104 is command B, " end of route guidance " is determined based on the table shown in Table 4. When the determination result obtained from the input determination means 104 is the command C, it is determined based on the table shown in Table 4 that " map the size one step larger. &Quot; When the determination result obtained from the input determination means 104 is the command F, based on the table shown in Table 4, " zoom out the map with two smaller sizes " is determined.

In the command input device of the present invention, operation setting means 108 is provided for arbitrarily setting the table shown in FIG. Therefore, the user can assign any action to a given command.

The operation control means 106 executes the operation selected by the operation selecting means 105. For example, route guidance is initiated or the map zooms in on the map one size larger.

The contact time detecting means 101, the contact number detecting means 102, the contact interval detecting means 103, the input determining means 104, the operation selecting means 105 and the operation control means 106 are shown in hardware or in FIG. As shown, it can be realized by a combination of hardware and software, such as the CPU 904, the RAM 904a, and the program ROM 904b. The processing flow of the CPU when the configuration is realized by the CPU and the program is shown in FIG.

First, the CPU determines whether the finger is touching the touch panel display 100 based on the signal from the touch panel display 100 (S501). If the finger touches, the number of times of contact is detected in step S502. Specifically, the contact frequency N increases. For example, assuming that the initial value of N is zero, when the process proceeds from step S501 to step S502, the contact count N is set to zero.

The CPU detects the contact period in step S503. In particular, the contact period T (N) is counted. N is equal to the contact number N. Further, the CPU determines in step S504 whether the finger has moved away from the touch panel display 100 based on the signal from the touch panel display 100, and if the finger is away, processing proceeds to step S505, and the finger If it is not separated, the process returns to step S503. That is, the contact period T (N) continues to count until the finger is away from the touch panel display 100.

The CPU detects a time interval between contacts in step S505. In particular, the time interval I (N) between the contacts is counted. N is equal to the contact number N. Further, the CPU determines in step S506 whether the finger is touching the touch panel display 100 based on the signal from the touch panel display 100, and returns to step S502 if the finger is touching. If the finger is not touching, the flow advances to step S507. In step S507, it is determined whether the command input by the user has ended, and if the command input is ended, the CPU proceeds to step S508, and returns to step S505 if it is not finished. Various methods can be used to determine if the command input has ended. For example, it is determined that the command input is terminated after a predetermined time (changeable by the user) has elapsed since the user's finger is moved away from the touch panel display 100.

Through the steps S505 to S507 described above, the time interval I (N) between the contacts is continuously counted from when the finger is moved away from the touch panel display 100 to the next time the finger touches the display. When the finger touches the touch panel display 100 in step S506, control returns to step S502, and the number of times of contact N is increased to perform a similar process. As a result, the contact periods T (2) and T (3) and the intervals I (2) and I (3) between the contacts are sequentially detected.

When the command input is terminated in step S507, the CPU detects N, T (1), T (2), I (1), I (2) and the like as shown in Fig. 3 detected by the above-described processing. The command is determined based on. Further, an operation is selected based on the command determined in step S508 and the table shown in FIG. 4 (S509), and control associated with the operation is executed (S510).

As described above, the command input device according to the first embodiment of the present invention comprises: contact time detecting means for detecting a period during which a finger continuously touches the touch panel display; Contact number detecting means for detecting the number of times a finger touches the touch panel display; Contact interval detecting means for detecting a period between when the finger is moved away from the touch panel display and when the finger is then brought into contact; Since input determination means for determining an input command is provided on the basis of the detection result obtained by the contact time detecting means, the contact number detecting means and the contact interval detecting means, the period of contact between the finger, the number of contacts, and the contact. Since commands can be input based on the time interval of, various commands can be input without visual inspection. Moreover, since the user can input by touching any position of the touch panel display with his finger, it is easy to enter a command without looking at the touch panel display at all.

(2nd Example)

The structure of the command input device according to the second embodiment of the present invention is shown in FIG.

In FIG. 6, the command input device includes a touch panel display 100; Contact time detection means (601) for detecting a period during which the finger continuously contacts the touch panel display (100); Contact number detecting means (602) for detecting the number of times a finger touches the touch panel display (100); Contact interval detecting means (603) for detecting a period between when the finger is moved away from the touch panel display (100) and when the finger is then brought into contact; Input determination means 104 for determining an input command based on detection results obtained by the contact time detecting means 601, the contact number detecting means 602, and the contact interval detecting means 603; Among the predetermined operations, operation selection means 105 for selecting an operation corresponding to the input command determined by the input determination means 104 based on the input command determined by the input determination means 104; Operation control means 106 for executing an operation selected by the operation selection means 105; Input for arbitrarily setting the coupling relationship between the detection results obtained by the contact time detecting means 601, the contact number detecting means 602, and the contact interval detecting means 603 and the input command determined by the input determining means 104. Combination setting means (107); operation setting means (108) for arbitrarily setting a coupling relationship between the input command determined by the input determination means (104) and the operation selected by the operation selection means (105); Vibration detection means (609); In order to prevent malfunction due to chattering, according to the detection result obtained by the vibration detecting means 609, a malfunction to control the contact time detecting means 601, the contact number detecting means 602 and the contact interval detecting means 603. Prevention means (610). In Fig. 6, components similar to those in Fig. 1 are given the same reference numerals and description thereof will be omitted.

The operation of the command input device of this embodiment configured as described above will be described.

The contact time detecting means 601, the contact number detecting means 602 and the contact interval detecting means 603 of this embodiment are chattering (when a user's finger touches or falls off the touch panel display 100, the finger momentarily To prevent malfunction due to touch or falling).

When chattering occurs, as shown in Fig. 7, the finger is momentarily dropped from the touch panel display 100 against the intention of the user (ΔI). Here, when the contact time detecting means, the contact number detecting means, and the contact interval detecting means process such finger action as a command input from the user, a malfunction occurs. In particular, T (2) detected by the contact time detecting means is almost zero, N detected by the contact number detecting means is about one larger than expected, and I (2) detected by the contact interval detecting means ΔI. As a result, the determination result obtained by the input determination means is not intended by the user.

Therefore, in order to prevent the above-mentioned malfunction, the contact time detecting means 601, the contact number detecting means 602 and the contact interval detecting means 603 of the present invention have a short time (for example, 10 ms or less) between the contacts. Is set to be determined as due to chattering, so this is not reflected in the detection result. Therefore, even if chattering occurs, no malfunction occurs.

In addition, when the command input device of the present invention is applied to a vehicle-mounted navigation device, chattering is likely to occur due to vibration of the vehicle during movement, and a time interval ΔI between the contacts is caused by chattering. It becomes larger than when stopped. Therefore, in the present embodiment, since the vibration detecting means 609 is provided in the vehicle or the command input device, the malfunction preventing means 610 according to the detection result, the contact time detecting means 601 and the contact number detecting means 602. ) And the contact interval detecting means 603 can control the time interval ΔI between the contacts for determining the effect of chattering. More specifically, when no vibration is detected by the vibration detecting means 609, the malfunction preventing means 610 has a time interval of 10 ms between the contacts in which the effect of chattering is determined based on the example of the table shown in FIG. When the vibration is detected by the vibration detecting means 609, the time interval between the contacts for which the effect of chattering is determined is set to be 100 ms or less. Therefore, the chattering effect can be effectively prevented even when the vehicle is moving.

Fig. 8 shows an example in which the time interval between the contacts for which the chattering effect is determined is controlled in two ways according to the presence or absence of vibration, but the present invention is not limited thereto, and the contact between the contacts for which the chattering effect is determined is The time interval may for example be controlled in three ways.

As described above, according to the command input device of the second embodiment of the present invention, the vibration detecting means for detecting vibration and the malfunction preventing means for preventing malfunction due to chattering in accordance with the detection result obtained from the vibration detecting means. By providing this, an optimal chattering effect prevention process can be achieved in accordance with the state of the vehicle.

The invention is ideal for a car navigation device with a touch panel display, for example.
