Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a user input device for inputting an object operation or a command to a computer, and more particularly to a user input for directly inputting an object operation or a command to a computer using a user's fingertip. Relates to the device.
[0002]
More specifically, it relates to a user input device that performs non-contact input of object operations and commands to a computer, and particularly recognizes information on two or more points, the shape of an approaching object, and distance information to the object. It is related with the non-contact-type user input device which can do.
[0003]
[Prior art]
Along with recent technological innovation, a general-purpose computer system, called workstation (WS) and personal computer (PC), is developed and marketed with relatively small size and low price, high added value and high functionality. It has deeply penetrated into daily life in universities and other research institutes, companies and other offices, and even ordinary households.
[0004]
Computer systems generally provide an “interactive” or interactive processing environment by driving in response to user input commands and displaying processing results on a display screen. As a recent trend, graphic-based user input has been realized from a character-based user input environment such as a DOS (Disk Operating System) shell screen via a conventional keyboard, that is, “Character User Interface (CUI)”. A transition to “GUI (Graphical User Interface)” can be mentioned. Under the GUI environment, a desktop simulating a computer system and countless icons are prepared on the display screen.
[0005]
On the desktop provided with the GUI, all resource objects handled on the computer system such as files are represented as icons. The user directly applies an operation to a display object on the screen using a mouse or the like to icons representing programs, data, folders, devices, etc. on the display screen (for example, click, drag and drag, etc.). (Drop), the computer can be operated intuitively. On the desktop, buttons such as a menu bar and a tool box are provided to instantly invoke various functions, that is, computer processing, and the command input format becomes increasingly intuitive and easy to understand. It is coming.
[0006]
With the introduction of the GUI environment, the user can sufficiently operate the computer without particularly learning the name of a specific command, the command operation method, or performing complicated key input.
[0007]
As a user input device that can be used in such a GUI environment, for example, a coordinate instruction device such as a mouse, a track point, a joystick, a tablet, or a touch pad is representative. Of these, the mouse is deeply established in the computer industry, and most users are accustomed to mouse operation based on drag and drop. It is no exaggeration to say that there is no need to train mouse operations when introducing a new computer in daily life situations such as in the office or home. GUIs based on mouse operations are already established among many users and provide a plurality of general-purpose functions.
[0008]
Under the GUI environment, the user can interactively understand and input data to the computer while being guided by the display contents on the computer screen. As an example in which such interactive input has further advanced, a user input device using a touch panel can be cited. In this case, since the touch panel that reads the coordinate value instructed from the pen or the fingertip of the user is superimposed on the screen, the user does not need to remove the line of sight from the screen unlike the case of operating the mouse. The display object can be directly pointed with his / her fingertip, so that the operability is further improved.
[0009]
However, the user input by the conventional touch panel requires the fingertip to actually touch the touch panel surface.
[0010]
In addition, if there are two or more contact points on the panel, each position cannot be measured independently. For example, when considering a usage pattern in which a plurality of people are placed around a touch panel to hold a conference, the fingertips of a plurality of participants may touch the touch panel at the same time. It cannot be recognized. The first touch may be given priority, or multiple touches may be confused or confused.
[0011]
Further, conventional touch panel type user input is based on point information input, and cannot recognize the shape of an approaching object, distance information to the approaching fingertip, and the like.
[0012]
[Problems to be solved by the invention]
An object of the present invention is to provide an excellent user input device that can directly input an object operation, a command, and the like to a computer using a user's fingertip.
[0013]
It is a further object of the present invention to provide an excellent user input device that can input object operations, commands, and the like to a computer in a non-contact manner.
[0014]
A further object of the present invention is to provide an excellent non-contact type user input device capable of recognizing information of two or more points, the shape of an approaching object, distance information to the object, and the like.
[0015]
[Means and Actions for Solving the Problems]
The present invention has been made in consideration of the above-mentioned problems, and is a non-contact type user input device that inputs in a non-contact format using a user's fingertip or the like,
A plurality of linear transmission electrodes;
A transmitter for supplying an alternating current for transmission to each of the transmission electrodes;
A plurality of linear receiving electrodes arranged so as not to contact each of the transmitting electrodes;
A receiver for receiving an alternating current flowing through the receiving electrode,
A circuit equivalent to a capacitor is formed at each intersection of the transmission electrode and the reception electrode,
This is a non-contact type user input device.
[0016]
According to the non-contact user input device having such a configuration, a first capacitor equivalent circuit equivalent to a capacitor is virtually formed at each intersection of the transmission electrode and the reception electrode.
[0017]
Further, in response to the approach of a conductive object such as a user's fingertip, a second capacitor equivalent circuit that is parallel to the first capacitor equivalent circuit is virtually formed.
[0018]
The capacitance of the second capacitor equivalent circuit changes in accordance with the degree of proximity to the conductive object such as a fingertip. Therefore, the alternating current passing through the first capacitor equivalent circuit connected in parallel with the second capacitor equivalent circuit similarly changes depending on the degree of proximity to the conductive object such as a fingertip. . By using such a phenomenon, the non-contact type user input device can measure not only that the fingertip is in contact but also the distance to the fingertip when approaching.
[0019]
The transmitter further includes a signal processing unit that scans an alternating current for each transmission electrode and detects an input position based on a positional relationship between the transmission electrode that has transmitted the alternating current and the reception electrode that has received the alternating current. You may have.
[0020]
In such a case, the non-contact user input device can measure the contour of the approaching object by tracking the intersection of the transmission electrode and the reception electrode where the input position is detected. That is, the non-contact user input device can not only detect that an object such as a user's fingertip is approaching but also recognize the shape of the object. Even when two or more users try to access the non-contact user input device at the same time, it is possible to recognize each person's fingertip separately.
[0021]
The transmitter may apply an alternating current to each transmission electrode while scanning. The non-contact type user input device may further include a signal processing unit that detects an input position based on a positional relationship between a transmission electrode that transmits an alternating current and a reception electrode that receives the alternating current.
[0022]
In the signal processing unit, the capacitance of the first virtual capacitor formed at the intersection of the transmission electrode and the reception electrode, and that a conductive object such as a user's fingertip approaches the intersection of the transmission electrode and the reception electrode. By utilizing the difference from the capacitance of the second virtual capacitor formed accordingly, it is possible to detect that the conductive object has approached.
[0023]
In addition, the signal processing unit detects the position of the conductive object by integrating the capacitance of a capacitor virtually formed between the conductive object such as a user's fingertip and each electrode. can do.
[0024]
In addition, a user input area formed by intersecting at least the plurality of transmission electrodes and the plurality of reception electrodes among the non-contact type user input device according to the present invention is displayed on the display screen of the display device by superimposing them. An integrated user input device can be configured. For example, the non-contact type user input device according to the present invention can be configured integrally with a liquid crystal display or an organic LED.
[0025]
For example, the non-contact type user input device according to the present invention may be configured integrally with a display device in which an anode electrode layer and a cathode electrode layer are laminated via an insulating layer.
[0026]
In such a case, a combination of one electrode layer and the other electrode layer can constitute a user input area in which the plurality of transmission electrodes and the plurality of reception electrodes intersect. That is, an AC voltage for detection may be applied to one electrode layer to which a DC voltage is applied, and an AC current received from the other electrode layer may be detected.
[0027]
Other objects, features, and advantages of the present invention will become apparent from a more detailed description based on embodiments of the present invention described later and the accompanying drawings.
[0028]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0029]
FIG. 1 schematically shows a basic configuration of a non-contact type user input device 1 according to an embodiment of the present invention.
[0030]
As shown in the figure, the non-contact type user input device 1 includes a plurality of linear transmission electrodes 11-1, 11-2,..., 11-m and a predetermined transmission for transmission to each of the transmission electrodes 11-1. A transmitter 12 that supplies an alternating current of a frequency (for example, 100 KHz) and a plurality of linear receiving electrodes 15-1, 15-2,... That receive an alternating current from each of the transmitting electrodes 11-1,. , 15-n and a receiver 16 that receives an alternating current flowing through each of the receiving electrodes 15-1,. The receiver 16 is an AM modulator composed of a band pass filter (BPF) 16A, an amplifier 16B, and a detector 16C that allows only an alternating current of a predetermined frequency band to pass therethrough, and converts the detection output into a digital signal. And an A / D converter 16D.
[0031]
Each of the receiving electrodes 15-1, 15-2,..., 15-n has an intersection with each of the transmitting electrodes 11-1, 11-2,. There is no contact between them. In other words, a circuit equivalent to a capacitor for accumulating electric charge is substantially formed at each intersection of the electrodes. Therefore, when an alternating current passes through the transmitting electrode, the alternating current flows through the intersection of the receiving electrode facing the transmitting electrode by electrostatic induction. The area where the transmission electrodes 11-1, 11-2,..., 11-m and the reception electrodes 15-1, 15-2,..., 15-n intersect is a user input in the non-contact type user input device 1. Configure the area. This user input area has a two-dimensional expanse as shown.
[0032]
The transmitter 12 applies an alternating current to each of the transmission electrodes 11-1,. Therefore, at a certain moment, an alternating current from the capacitor equivalent circuit at the intersection with the corresponding transmitting electrode flows through each receiving electrode 15-1,..., And the receiving electrode that has received the alternating current receives the alternating current. The input position can be detected based on the positional relationship with the electrode. For example, two-dimensional user input can be detected via the user input area by performing predetermined arithmetic processing on the output signal at each of the receiving electrodes 15-1... .
[0033]
In the illustrated example, the transmission electrodes 11-1, 11-2,..., 11-m are arranged substantially in parallel, and the reception electrodes 15-1, 15-2,. The electrodes are arranged in a direction orthogonal to the electrodes 11-1,..., And the user input area is a substantially planar area in which the electrodes are uniformly combined on the mesh. However, the gist of the present invention is not particularly limited to such a form. If the transmitting electrodes and the receiving electrodes are in contact with each other without being in contact with each other, the shape may be other than a plane, for example, a spherical shape or other curved surface There may be.
[0034]
In FIG. 2, a certain intersection between the transmission electrode 11 and the reception electrode 15 is shown enlarged. FIG. 3 shows an equivalent circuit at the intersection of the transmission electrode 11 and the reception electrode 15.
[0035]
At the intersection where the transmission electrode 11 and the reception electrode 15 intersect, a circuit equivalent to a capacitor is formed as shown in FIG.
[0036]
Here, when an AC voltage is applied to the transmission electrode 11 side, occur capacitive coupling by the capacitance C a between the transmission electrodes 11 and the receiving electrode 15, an alternating current is generated in the receiving electrode 15. Intensity of the current passing through the capacitor C a is a band-pass filter 16A tuned to the oscillation frequency of the AC voltage in the oscillator 12, an amplifier 16B, detector 16C, and the signal processing by each unit of the A / D converter 16D Is taken out as digital data. Intensity of the alternating current received by the receiving electrode 11, depends only on the capacitance C a of the capacitor.
[0037]
The electrostatic capacitance Ca is static and maintains a fixed value as long as the transmission electrode 11 and the reception electrode 15 are not deformed. Therefore, as long as the same AC voltage is applied to the transmission electrode 11 side, the intensity of the AC current received on the reception electrode 15 side is constant.
[0038]
Next, a mechanism for detecting an object such as a user's fingertip in a non-contact manner using such a combination of the transmission electrode 11 and the reception electrode 15 will be described.
[0039]
FIG. 4 shows a state where the user's fingertip is approaching a certain intersection between the transmission electrode 11 and the reception electrode 15. FIG. 5 shows an equivalent circuit of the intersection between the transmission electrode 11 and the reception electrode 15 when a user's fingertip approaches a certain intersection between the transmission electrode 11 and the reception electrode 15.
[0040]
The intersection with the transmitting electrode 11 a receiving electrode 15 intersect, as described above, capacitor C a equivalent circuit is formed.
[0041]
A human body such as a fingertip can be regarded as a virtual ground point (earth). Accordingly, the equivalent circuit thereof, and a capacitor C a which is formed between the transmission electrode 11 and the receiving electrode 15, virtual capacitor serially formed between each body and the transmission electrode 11 and the human body and the reception electrode 15 C b1 and C b2 are connected in parallel.
[0042]
Therefore, when an AC voltage is applied to the transmission electrode 11 side, an AC generated by capacitive coupling due to the capacitance C a between the transmission electrode 11 and the reception electrode 15 by the amount of current flowing into the ground via the capacitor C b1. The intensity of the current, that is, the current detected on the receiving electrode 15 side is weakened.
[0043]
The electrostatic capacitance Ca is static and maintains a fixed value as long as the transmission electrode 11 and the reception electrode 15 are not deformed. On the other hand, the electrostatic capacitances C b1 and C b2 of the virtual capacitor formed in series between the human body and the transmission electrode 11 and the human body and the reception electrode 15, respectively, As it gets closer to 15, it grows.
[0044]
For this reason, when the same AC voltage is applied to the transmission electrode 11, the intensity of the AC current detected by the reception electrode 15 decreases as the human body approaches the transmission electrode 11 and the reception electrode 15.
[0045]
By utilizing such a phenomenon, the processor 20 uses the received signal that is AM-modulated by the AM modulator 16 and further converted into a digital format by the A / D converter 16D, so that the human body approaches the intersection between the electrodes. It is possible to determine whether or not the human body is approaching (distance).
[0046]
As shown in FIG. 1, in the non-contact user input device 1 according to the present embodiment, such intersections of the transmission electrodes 11-1 and the reception electrodes 15-1 are arranged in an m × n matrix. Has been. For example, the intersections of these electrodes can be arranged on an input panel consisting of a predetermined plane (or curved surface).
[0047]
An AC voltage is applied to each of the transmission electrodes 11-1, 11-2,. And corresponding to each, the alternating current which generate | occur | produces in each receiving electrode 15-1, 15-2, ..., 15-n is measured sequentially, and the human body is approaching which intersection on the user input area. Can be determined.
[0048]
In the non-contact user input device 11 according to the present embodiment, since the electrostatic action is used, it is not necessary for the human body to be in direct contact with the electrode in order to detect the human body such as the fingertip of the user. In addition, the distance from the input surface to the fingertip can be measured by integrating the detected values obtained at nearby intersections and performing a general geometric calculation or the like.
[0049]
Further, according to the configuration shown in FIG. 1, each intersection between the electrodes can be driven independently. That is, since the detection value can be taken out independently from each intersection, when a plurality of objects (for example, the right and left hands of the same user or the hands of a plurality of users) approach the user input area at the same time. If the distance is longer than the pitch interval between the intersections, these can be recognized as independent objects. That is, the positions of a plurality of objects can be measured simultaneously.
[0050]
Further, by tracking the intersection where the approach of the object is detected at the same time, the shape or contour of the approaching object can be captured.
[0051]
FIG. 6 illustrates a modification of the non-contact user input device 1.
[0052]
When the user's fingertip approaches an area surrounded by the grid points A, B, C, and D, the transmission electrodes 11-i and 11-j, the reception electrodes 15-p and 15-q, and the user's fingertip Virtual capacitors C I , C J , C P , and C Q are formed between the fingertips.
[0053]
The capacitances C I , C J , C P , and C Q of these virtual capacitors change according to the distance between each electrode and the user's fingertip.
[0054]
Therefore, by integrating values from a plurality of intersections between the human body and the electrodes, the position of the hand in the middle of each intersection can be measured. That is, the accuracy of position measurement of the non-contact user input device 1 according to the present embodiment can be made finer than the interval between the intersections between the electrodes.
[0055]
FIG. 7 illustrates another modification of the non-contact user input device 1.
[0056]
As already described with reference to FIG. 1, in the non-contact user input device 1 according to the present embodiment, the intersection of the transmission electrodes 11-1... And the reception electrodes 15-1. n is arranged in a matrix. Further, according to the configuration shown in FIG. 1, each intersection between the electrodes can be driven independently, and the detection value can be extracted independently from each intersection.
[0057]
Therefore, as shown in FIG. 7, when there are a plurality of user's fingertips in the user input area, these can be recognized independently at an intersection in the vicinity of each user's fingertip. As a result, simultaneous input from multiple users can be received using a single user input device.
[0058]
FIG. 8 illustrates another modification of the non-contact user input device 1.
[0059]
As already described with reference to FIG. 1, in the non-contact user input device 1 according to the present embodiment, the intersection of the transmission electrodes 11-1... And the reception electrodes 15-1. n is arranged in a matrix. However, in the example shown in FIG. 8, the intervals between the transmission electrodes 11-1, 11-2,..., 11-m and the reception electrodes 15-1-1, 15-2,. The scanning speed at which the transmitter 12 applies an AC voltage to each transmission electrode 11-1 is sufficiently high.
[0060]
In such a case, as shown in FIG. 8, when the user brings the palm close to the user input area, the object, that is, the shape of the palm can be recognized by tracking the intersection where the approach is detected. it can.
[0061]
That is, the contactless user input device 1 according to the present embodiment can recognize the shape of the object by sufficiently reducing the pitch interval between the electrodes and sufficiently increasing the scanning speed of the transmission electrode.
[0062]
It is also conceivable to apply the non-contact user input device 1 according to the present embodiment in combination with other devices. For example, a display-integrated user input device can be configured by superimposing the non-contact user input device 1 on a flat display such as a liquid crystal display (LCD) or an organic EL. According to such a user input device, the user can input commands to the computer intuitively and easily while being guided by the content of the GUI screen to be displayed and output. The user can perform an input operation without diverting his / her line of sight from the display screen, and the risk of operation is reduced.
[0063]
FIG. 9 schematically illustrates a cross-sectional configuration of the non-contact user input device 1 configured integrally with a display device made of a light emitting element made of a conductive polymer, that is, an organic LED.
[0064]
In the example shown in the figure, an anode electrode layer and a cathode electrode layer made of a conductive polymer are laminated via an insulating layer made of an organic material. Further, the anode electrode and the cathode electrode are arranged perpendicular to each other. This is similar to the configuration shown in FIG. 1 in which the transmitting electrodes 11-1 and the receiving electrodes 15-1 are arranged so as not to contact each other.
[0065]
In the organic display, in order to cause each pixel to emit light, in one electrode layer, a DC voltage is sequentially applied to each electrode in the screen scanning direction.
[0066]
In the present embodiment, an AC voltage for human body detection is superimposed and applied to a DC voltage flowing through one electrode layer. As a result, the other electrode layer receives an alternating current. At intersections where human bodies such as the user's fingertips are approaching, the intensity of the received alternating current decreases, so the location of the user's fingertips can be specified and the shape of the approaching object can be recognized. You can do it.
[0067]
According to the configuration as shown in FIG. 9, the display device can be used as it is as a non-contact type user input device without changing the screen configuration of the organic display.
[0068]
Further, the organic display is generally flexible and can be bent freely. Therefore, according to the application example as shown in FIG. 9, a spherical or cylindrical display unit integrated with user input can be configured.
[0069]
[Supplement]
The present invention has been described in detail above with reference to specific embodiments. However, it is obvious that those skilled in the art can make modifications and substitutions of the embodiments without departing from the gist of the present invention. In other words, the present invention has been disclosed in the form of exemplification, and should not be interpreted in a limited manner. In order to determine the gist of the present invention, the claims section described at the beginning should be considered.
[0070]

[0073]
In the non-contact type user input device according to the present invention, a first capacitor equivalent circuit equivalent to a capacitor is virtually formed at each intersection of the transmission electrode and the reception electrode. Further, in response to the approach of a conductive object such as a user's fingertip, a second capacitor equivalent circuit that is parallel to the first capacitor equivalent circuit is virtually formed. The capacitance of the second capacitor equivalent circuit changes according to the degree of proximity to the conductive object such as a fingertip, and as a result, the alternating current passing through the first capacitor equivalent circuit changes. . Therefore, by using such a phenomenon, it is possible to measure not only that the fingertip is in contact but also the distance to the fingertip when approaching.
[0074]
Further, by scanning and inputting an alternating current to each transmission electrode, the input position can be detected based on the positional relationship between the transmission electrode that has transmitted the alternating current and the reception electrode that has received the alternating current. By tracing the intersection of the transmission electrode and the reception electrode that have detected the input position, the contour of the approaching object can be measured. That is, the non-contact user input device can not only detect that an object such as a user's fingertip is approaching but also recognize the shape of the object. Even when two or more users try to access the non-contact user input device at the same time, it is possible to recognize each person's fingertip separately.
