Description

  The present invention relates to an input device for correcting input information detected by the input device in the main device in a system including a main device that is an information processing device and an input device that is detachably connected to the main device. The present invention relates to a main body device and an input information correction system.

  The form of the input device as a user interface for transmitting the input operation by the user to the main unit has been diversified. A typical example of such an input device is a mouse or a touchpad, but motion capture has been increasingly applied to consumer devices such as input devices with a touch panel, pen tablets, and game consoles that are already widely used. Various devices such as a camera can be listed.

  If the sensor of such an input device does not have sufficient detection accuracy, a shift occurs between the position where the user performs an input operation and the input position detected by the input device. As a result, there may be a problem that the operation of the main device performed based on the input information acquired from the input device is different from that intended by the user. For example, it may happen that a desired GUI button displayed on the screen of the display unit provided so as to overlap with the touch panel cannot be pressed or another button is pressed. This is a problem caused by the fact that continuous input values do not exactly match digital discrete values, and can be said to be a problem peculiar to input devices that detect analog quantities such as position and movement in space. .

  In the above description, the position detection accuracy problem has been described. However, the direction detection accuracy may be a problem. For example, a high-resolution mouse widely used for drawing using CAD has a lower movement detection threshold than a normal mouse, and detects a slight movement of the mouse to move the cursor on the screen. Can do. However, on the other hand, there is a tendency that the direction in which the mouse is actually moved differs from the direction in which the cursor moves on the screen. In the case of a mouse, it can be operated while following the cursor displayed on the screen, so a slight shift is not a big problem for normal use, but a precise response like drawing is required. In some circumstances, such shifts are not negligible even to a small extent.

In order to eliminate the above-described displacement in position and direction, input information is generally corrected after being transmitted to the main unit, and many techniques for improving the accuracy of correction have been disclosed (for example, Patent Document 1).
The correction referred to here is a process in which the arithmetic processing unit of the main device substitutes an input value acquired from the input device into a predetermined correction formula and handles the obtained value as an input value. The predetermined correction formula is defined by applying predetermined information (correction information) to a formula prepared at the time of manufacturing the main body device in advance. This correction information is, for example, sensor offset, gain, span, vector value and its coefficient, etc., and takes different values depending on individual differences of input devices. The correction information is determined by, for example, the following calibration (calibration) work. That is, if the input device is an input device with a touch panel that is installed so as to overlap with the screen of the display unit, the touch by a pointer such as a finger or a pen on a plurality of targets displayed on the display unit is detected and the detection is performed. The correction information is determined so as to convert the coordinates of each touch position into the coordinates of the corresponding target display position by referring to the coordinates of the plurality of touch positions and the display positions of the plurality of targets on the display unit.

JP 2012-146266 A

  When the input device is not provided integrally with the main device at the time of manufacture, a calibration operation for determining correction information needs to be performed by a user who uses the input device and the main device in combination. The calibration operation is usually performed when the input device and the main device are connected for the first time, and correction information determined by this is generally stored in a storage area in the main device. Accordingly, when the main apparatus is repaired or replaced due to a failure and the correction information stored in the main apparatus is lost, the user must perform a calibration operation each time. The calibration work needs to be performed accurately in order to influence the subsequent substantial detection accuracy of the input device, and it is not preferable to force such a work to a user who is not familiar with the operation many times.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the number of calibration operations required when the main body device and the input device are used in combination and to improve convenience for the user. is there.

The first invention made to solve the above problems detects a position and / or movement in a two-dimensional or three-dimensional space designated by the user, and transmits the detection result to the main unit as input information. An input device separable from the main device,

b) Input device correction information transmission means for transmitting the correction information stored in the correction information storage means to the main body device;
It is characterized by providing.

Here, “correction” in the present invention is a concept related to processing for improving the substantial detection accuracy of the input device, and applies a predetermined formula to a detection result based on input information and converts the value. Means. As a specific example, adjustments such as the coordinates of the touch position on the touch panel and the moving direction of the mouse cursor are included in the “correction” of the present invention. The “movement” includes the amount and direction of movement.
Examples of the input device in the present invention include an input device with a touch panel, a pen tablet, a mouse, a controller for a game machine with a motion sensor, a camera for motion capture, and the like.

According to said structure, the correction information for a main body apparatus to correct input information is memorize | stored by a correction information storage means, and is transmitted to a main body apparatus by an input device correction information transmission means. Therefore, even when the main unit does not have correction information, or when correction information held by the main unit is lost due to repair or replacement of the main unit, the main unit receives correction information from the input device. It can be received and appropriate corrections can be made based on this. Therefore, it is not necessary to perform calibration work for determining correction information every time the main apparatus is repaired or replaced, and convenience for the user can be improved.
Further, since the input device includes the correction information storage means, it is possible to perform calibration work in advance at the manufacturing stage of the input device. In this case, if a person familiar with the operation performs the calibration work, the input device can be provided to the user with a substantially higher detection accuracy than when a user unfamiliar with the operation performs the calibration work. . Furthermore, if a proficient person performs calibration work in advance at the time of manufacturing, a certain level is guaranteed for the substantial detection accuracy when the input device is provided to the user, so the original detection accuracy is low and low. A simple sensor can be used as a component, and the manufacturing cost of the input device can be reduced.
The input device correction information transmitting means may transmit the correction information to the main body device in response to a request from the main body device, or spontaneously when the input device is activated or when a connection with the main body device is established. Alternatively, correction information may be transmitted to the main device.

The input device further includes:
c) Input device correction information receiving means for receiving the correction information from the main device may be provided.
According to this configuration, the correction information storage unit stores the correction information received from the main device by the input device correction information receiving unit, so that the user performs calibration work on the main device side and arbitrarily updates the correction information. Can do.

According to a second aspect of the present invention, there is provided an input device that receives, as input information, a position and / or movement in a two-dimensional or three-dimensional space designated by a user, which is detected by the input device. A separable main unit,
a) Main unit correction information receiving means for receiving correction information for correcting the input information from the input device;
b) correction processing means for correcting the input information based on the correction information received by the main unit correction information receiving means from the input device;
It is characterized by providing.

  According to the above configuration, the main unit correction information receiving unit receives the correction information from the input device, and the correction processing unit corrects the input information based on the received correction information. Therefore, even when the main unit does not have correction information, or when the correction information held by the main unit is lost due to repair or replacement of the main unit, the main unit correction information receiving means is connected from the input device. Using the received correction information, the correction processing means can appropriately correct the input information. Thereby, it is not necessary to perform calibration work for determining correction information every time the main body apparatus is repaired or replaced, and convenience for the user can be improved.

The main unit further includes:
c) correction information generating means for generating the correction information;
d) main unit correction information transmitting means for transmitting the correction information generated by the correction information generating means to the input device;
May be provided.
According to this configuration, the correction information generated by the correction information generation unit is transmitted to the input device, so that the user can arbitrarily update the correction information by performing calibration work on the main body side.

  In order to solve the above problems, a third invention is an input information correction system including an input device and a main device that are separably connected, the input device according to the first invention, and the second device. And a main body device according to the invention.

According to the first to third inventions, it is possible to reduce the number of calibration operations required when using the main body device and the input device in combination, and to improve convenience for the user.
Furthermore, by storing the correction information on the input device side, the input device has high detection accuracy by a software method. As a result, it is not necessary to guarantee the detection accuracy of the input device with hardware, so that the input device can be configured with a simpler structure and less expensive parts, which contributes to a reduction in manufacturing cost.

For example, in the case of a capacitive touch panel, the touch panel 11 includes an electrode array that is wired in plural numbers in the X-axis direction and the Y-axis direction. In the present embodiment, as an example, the touch panel 11 is a capacitive touch panel. The touch panel 11 detects a touch by detecting a change in the capacitance value of each electrode constituting the electrode array, and outputs the capacitance value as an input signal.
The communication unit 12 is a unit that manages connection with an external device or the like. In the present embodiment, the communication unit 12 is connected to the communication unit 21 included in the main body device 2.
The correction information storage unit 13 stores correction information received from the main device 2 via the communication unit 12, and is realized by a non-volatile storage device such as a flash memory. Here, the correction information is information such as a coefficient of a correction formula, which will be described later, used when the main body device 2 corrects the coordinates of the touch position of the user detected by the touch panel 11.
The request receiving unit 14 receives a correction information request signal from the main body device 2 described later, and acquires correction information from the correction information storage unit 13.

In addition to this, the main apparatus may include an input unit (not shown).
Similar to the communication unit 12, the communication unit 21 is a unit that controls connection with an external device or the like, and is connected to the communication unit 12 included in the input device 1 in this embodiment.
The display unit 22 displays information handled by the main device 2 and is realized by a display device such as an LCD (Liquid Crystal Display).

It is realized by a nonvolatile storage device such as a ROM, EEPROM (registered trademark) (Electrically EPROM), HDD (Hard Disc Drive), SSD (Solid State Drive). In addition, the main unit 2 may be provided with a temporary storage unit composed of a volatile storage device such as a RAM.
The main unit 2 may be connected to an analytical instrument such as a liquid chromatograph mass spectrometer (LC-MS) in a wired or wireless manner, or may be provided integrally, but is out of the scope of the present invention. Illustration is omitted.

The control unit 23 controls functions of each element included in the main device 2 and controls the operation of the main device 2. The control unit 23 is realized by a CPU (Central Processing Unit) or the like, for example. Each element to be described later is realized by the CPU as the control unit 23 reading a program stored in the ROM or the like into the RAM or the like and executing the program.
As shown in FIG. 1, the control unit 23 includes, as functional blocks, a coordinate specifying unit 231, a correction information generation unit (correction information generation unit) 232, a correction information acquisition unit 233, a correction processing unit (correction processing unit) 234, and system management. A display unit 235 and a display control unit 236.

The coordinate specifying unit 231 acquires an input signal detected by the touch panel 11 via the communication unit 21 and specifies the coordinates of the position where the user performs a touch operation from the capacitance value of each electrode. As a method for specifying the coordinates, for example, a known method described in Patent Document 1 can be used.
The correction information generation unit 232 generates correction information. Specifically, correction information required when the correction processing unit 234 corrects the coordinates specified by the coordinate specifying unit 231 is determined by correction information determination processing described later. The correction information generation unit 232 further transmits the determined correction information to the input device 1 via the communication unit 21.
The correction information acquisition unit 233 acquires correction information from the input device 1 via the communication unit 21. Specifically, the correction information acquisition unit 233 transmits a correction information request signal to the input device 1, and the correction information read out from the correction information storage unit 13 by the request reception unit 14 in response to the correction information request signal, Obtained via the communication unit 21.
The correction processing unit 234 corrects the coordinates specified by the coordinate specifying unit 231. Specifically, the correction information acquired by the correction information acquisition unit 233 added to the predetermined correction formula set at the time of manufacturing the main body device 2 is applied to the coordinates specified by the coordinate specification unit 231, Convert the value. The predetermined correction formulas are, for example, the following formulas (1) and (2).
x = ax '+ b (1)
y = cy '+ d (2)
Here, (x ′, y ′) is the coordinates before correction, and (x, y) is the coordinates after correction. At this time, coefficients a, b, c, and d are correction information in the present invention.
The system management unit 235 manages various programs (OS (Operating System), middleware, application programs, etc.) (not shown) that operate on the main device 2. The coordinates corrected by the correction processing unit 234 are transmitted to the system management unit 235, and various programs operate based on the corrected coordinates.
The display control unit 236 outputs video signals of the various types of information to the display unit 22 in order to visualize the various types of information processed by the control unit 23 on the display unit 22.

  FIG. 2 shows an example of the appearance of the input information correction system 100. The main body device 2 is an analysis control device that controls the operation of the analysis device connected to an analysis device (not shown) by wire or wirelessly. The input device 1 including the touch panel 11 is superposed on the display unit 22. Installed and used. In the figure, the input device 1 is physically connected to the main device 2 by the network cable NW, but may be connected by a wireless LAN or the like.

  An example of an actual use scene is shown in FIG. FIG. 3 is a diagram illustrating a screen display example by the display unit 22 illustrated in FIG. 2 together with the input device 1 including the touch panel 11 superimposed on the display unit 22. The display unit 22 is instructed to adjust analysis parameters such as pressure and temperature, and to switch display screens, along with analysis result images 30 such as waveform lines and data values created from analysis data received from an analysis instrument. A plurality of GUI buttons 31 to be received are displayed. The user presses the GUI button 31 by touching the touch panel 11 with the indicator (finger) F at the display position of the desired GUI button 31 while confirming the analysis result on the display screen of the display unit 22. Change analysis parameters and switch display screens.

[Flow of correction information determination process]
Here, in the input information correction system 100, the following calibration operation is performed in advance in order to correct the deviation between the position where the user actually performed the touch operation and the touch position recognized by the main body device 2. Need to be FIG. 4 is an explanatory diagram of the calibration work in the input information correction system 100. Hereinafter, the flow of correction information determination processing in the input information correction system 100 will be described with reference to FIG. 4 which is a flowchart and FIG. 5 which is an explanatory diagram of calibration work.

  When the calibration work starts, first, the display control unit 236 displays the target 50 at a predetermined position on the screen of the display unit 22 according to an instruction from the correction information generation unit 232 (step S101). The target 50 is a target point to be touched by the user in the calibration operation. A plurality of targets 50 are preferably displayed on the screen of the display unit 22, and in the present embodiment, a plurality of targets 50 are sequentially displayed on the screen one by one. As another example, a plurality of targets 50 may be simultaneously displayed on the screen. The display position of the target 50 may be displayed near the four corners of the screen of the display unit 22 or may be displayed at random positions.

  When the target 50 is displayed, the touch panel 11 next detects a touch (step S102). Specifically, the capacitance value of each electrode is output as an input signal, triggered by a change in the capacitance value of the electrodes included in the electrode array. Subsequently, the communication unit 12 transmits this input signal to the communication unit 21 of the main device 2 (step S103).

  Next, the coordinate specifying unit 231 specifies the coordinates of the touch position (step S104). Specifically, when the communication unit 21 receives the input signal in step S103, the coordinate specifying unit 231 acquires the received input signal, and the coordinates of the position where the user performs the touch operation from the capacitance value of each electrode. Is identified. If the displayed number of targets 50 has not reached the predetermined number (No in step S105), the correction information determination process returns to step S101.

When Steps S101 to S104 are performed for a predetermined number of targets 50 (Yes in Step S105), the correction information generation unit 232 generates correction information (Step S106). Specifically, the correction information generation unit 232 refers to the coordinates of each display position of the target 50 in step S101 and the coordinates of the touch position specified in step S104, and converts the latter coordinates into the former coordinates. Therefore, appropriate correction information is generated. As an example, the coordinates of the display position of the target 50 shown in FIG. 5 are (30, 30), and the coordinates of the touch position 51 specified as a result of the user touching the target 50 with the indicator F are (15, 45). Suppose that In this case, according to the correction information for correcting the coordinates (15, 45) of the touch position to (30, 30), that is, according to the above equations (1) and (2), x = 30, y = 30, x ′ = 15 , y ′ = 45, the optimum coefficients a, b, c and d are obtained.
Of course, if the number of targets 50 to be displayed is large and the display positions of a plurality of targets 50 are widely dispersed on the screen, more accurate correction information is required. The display number and display position of the target 50 may be appropriately determined according to the time required for the calibration operation, the tolerance of detection accuracy, and the like.

Then, the correction information generation unit 232 transmits the generated correction information to the communication unit 12 of the input device 1 via the communication unit 21 (step S107).
The correction information received by the communication unit 12 is stored in the correction information storage unit 13 (step S108).

  Through the processing described above, the correction information related to the input device 1 is determined, and the determined correction information is stored in the correction information storage unit 13 included in the input device 1. The correction information generated by the correction information generation unit 232 in step S106 may be stored in the storage unit 24 of the main device 2 or a temporary storage unit (not shown).

[Flow of input information correction processing]
Next, the flow of input information correction processing in the input information correction system 100 will be described with reference to FIG. 6 which is a flowchart.
First, the correction information acquisition unit 233 determines whether correction information related to the input device 1 exists in the storage unit 24 in the main body device 2 or a temporary storage unit (not shown) (step S201). The timing at which this determination is performed may be when the main device 2 is activated or when the connection with the input device 1 is established.
When the correction information related to the input device 1 does not exist in the main device 2 (No in step S201), the correction information acquisition unit 233 transmits a correction information request signal to the communication unit 12 of the input device 1 (step S202). .
The correction information request signal received by the communication unit 12 is notified to the request reception unit 14, and the request reception unit 14 reads the correction information stored in the correction information storage unit 13 in response to the request (step S203). The read correction information is transmitted to the communication unit 21 of the main device 2 via the communication unit 12 (step S204). The transmitted correction information is acquired by the correction information acquisition unit 233 via the communication unit 21.

By the processing so far, the main body device 2 acquires the correction information related to the input device 1. In the following, input signal correction processing based on the acquired correction information is performed.
The subsequent processes related to steps S205 to S207 are the same as steps S102 to S104 in the correction information determination process described above.

Next, the correction processing unit 234 corrects the touch position coordinates based on the correction information (step S208). Specifically, the correction processing unit 234 adds the correction information acquired by the correction information acquisition unit 233 in step S204 to the predetermined correction formula set at the time of manufacturing the main body device 2 and coordinates in step S207. This is applied to the coordinates specified by the specifying unit 231.
Subsequently, the correction processing unit 234 outputs the corrected coordinates to the system management unit 235 (step S209). As a result of this step, the system management unit 235 outputs an operation signal indicating that a touch has been made at the position of the coordinate after the correction in step S208 for each program operating on the main device 2. As a result, for example, the analysis control software that displays a screen as shown in FIG. 3 recognizes that a touch operation has been performed on a predetermined GUI button 31, and presses the GUI button 31 or the like. Thereafter, the process returns to the position before step S206, and if a new input signal is obtained, the touch position coordinates are sequentially corrected.
When it is determined in step S201 that the correction information related to the input device 1 already exists in the main device 2 (Yes in step S201), steps S202 to S204 are skipped, and the main device 2 is the own device. The touch position coordinates are corrected based on the held correction information. Alternatively, when the correction information is not stored in the main device 2, the correction information acquisition unit 233 requests the correction information every time the main device 2 is activated or the connection with the input device 1 is established without providing step S201. A signal may be transmitted.

According to the processing described above, the correction information related to the input device 1 is stored in the correction information storage unit 13 in the input device 1, and the correction information request from the correction information acquisition unit 233 is performed when the main body device 2 performs the correction process. In response to the signal, it is read out to the main device 2 side. Accordingly, since it is not necessary for the main device 2 to hold the correction information, calibration is not required every time the main device is repaired or replaced, and convenience for the user can be improved.
Although only the touch operation has been described above, it goes without saying that the input information correction processing described above can be similarly applied to a drag operation, a flick operation, and the like.

  Further, the calibration work described above is not necessarily performed by the user, and may be performed by a person who is proficient in the calibration work in the manufacturing stage of the input device 1. In this case, for the main unit used in connection with the input device 1, it is necessary to know the standard of the dimensions of the display unit at the time of the configuration work, but it is known that it is used only in a specific combination If so, such pre-shipment calibration is extremely useful. In other words, not only calibration work by the user is unnecessary, but also correction based on more accurate correction information obtained by calibration by a skilled person is performed, so that it is substantially more than when a user unfamiliar with operation performs calibration work. The user is provided with the input device 1 in a state where the detection accuracy is improved. This eliminates design limitations in the prior art, such as using an expensive sensor with high original detection accuracy as a component, so that even a user unfamiliar with the operation can properly perform calibration work. Thus, the manufacturing cost of the input device 1 can be reduced.

  In the above-described embodiment, an example in which the input device includes a touch panel as a detection unit has been described. However, the input device according to the present invention is not limited to this, and any input device that can be separated from the main body device having detection means for detecting a position and / or movement in a two-dimensional or three-dimensional space as an approximate value by an input signal It is a concept that includes an input device. Specifically, for example, an input signal detected by a pen tablet as an input device, a mouse, a controller for a game machine with a motion sensor, a camera for motion capture, or the like is corrected by a main body device separable from the input device. The input information correction system according to the present invention can be applied to the system.

  As illustrated above, the input device according to the present invention can be used not only in two dimensions but also in three dimensions (on the X, Y, and Z coordinates) as shown in FIG. In this case, for example, light emitted from an infrared transmitter 70 installed in the vicinity of the display unit 22a is received by a camera provided in the input device 71 held by the user, thereby obtaining three-dimensional coordinates for the display unit 22a. What is necessary is just to specify.

  In the above-described embodiment, the correction of the position in the two-dimensional or three-dimensional space and the correction information therefor have been described, but the information for correcting the moving direction in the space is also included in the correction information of the present invention. It is. For example, if the input device is an optical mouse, the correction information is a coefficient applied to a predetermined correction formula when the main body device corrects the moving direction based on the detection result of the optical sensor. The correction information in this case may be stored in the correction information storage unit included in the optical mouse, as in the input device 1 described in the above embodiment.

  The input device, the main device, and the input information correction system including the input device according to the present invention have been described above by way of examples. However, the above is only an example, and modifications, improvements, and corrections are appropriately made within the spirit of the present invention. You may do. For example, in the above-described embodiment, the correction information acquisition unit 233 provided in the main body device 2 transmits a correction information request signal to the input device 1, and the request reception unit 14 provided in the input device 1 responds to the request by the correction information acquisition unit 14. In the above description, the correction information is read from the storage unit 13 and transmitted to the main device 2. However, the input device 1 may transmit the correction information stored in the correction information storage unit 13 to the main body device 2 when the input device 1 starts up or when the connection with the main body device 2 is established. Good.

  In the above-described embodiments and application examples, the input signal detected by the input device has been described as being output as the coordinates on the display unit and the moving direction by the main device, but the output mode of the input signal is described below. It is not limited to. For example, the main device may control the lighting state of the lamp provided in the main device and the pressed state of the hardware button based on the corrected input signal. In addition, the main device controls the operation of another device connected to the main device by wire or wireless based on the corrected input signal, or outputs the corrected input signal to another device. It can also be.
