Description

  The present invention relates to an input device such as a keyboard and an information input display system such as a PC (personal computer) using the input device.

  For example, when operating a PC, a monitor is generally placed in front of an operator in a sitting state, and a keyboard is placed on a desk or knee. This is because the operator can check the key positions by looking at the keyboard surface without looking away from the monitor.

  By the way, if the operator can input keys into the computer in an arbitrary posture, more comfortable operation of the PC becomes possible. For example, if you can enter keys even when you are lying on your back, you will be able to operate the computer for people who are lying on the bed, such as the sick or disabled, and you can lie on your back and use a computer with a comfortable posture. It is possible to satisfy the request to operate. However, in the current PC, due to its configuration, the posture during key input operation is limited, and key input cannot be performed in an arbitrary posture.

In order to operate the PC in a supine state, it is necessary to place the monitor face down on the operator, and the position of the keyboard is also a problem.
If you place the monitor face down on the operator and place the keyboard on the operator's belly or crotch with the keyboard face up, the operator may see the keyboard face. I can't check the key position. Anyone who can perform blind touch (key input without looking at the board surface) will not pose any problems, but it is difficult for those who are not familiar with the key arrangement. Also, if the keyboard is placed on the operator's belly or crotch, it is not suitable for long-time operation because it is not possible to perform key input in a comfortable natural state when lying on its back.

  If you place the keyboard above the operator and face the board down, the operator can input keys while checking the keyboard surface, but this requires you to raise your hand for each key entry. It is even more difficult to enter keys with an easy posture.

One of the methods that allows a person who cannot perform a blind touch to input a key without looking at the keyboard surface is to attach a touch sensor to the top surface of the key and display information on the key touched by the finger on the monitor. It has been proposed (see Patent Document 1).
Japanese Patent Application No. 91307

  With the method of Patent Document 1, it is possible to know the information of the key touched by the finger without looking at the surface of the keyboard, and it is possible to input the key by looking only at the monitor. However, this method is also proposed on the assumption that key input is performed in a sitting state, and even if an attempt is made to operate the PC in an arbitrary posture such as on its back using this method, There is a limitation, and it is not possible to enter keys easily in any posture.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an input device that allows an operator to input keys in an arbitrary posture and an information input display system using the input device.

  An input device according to the present invention has a panel surface on which keys to be in charge with the right hand are arranged, and is provided independently of a right hand side input unit that generates a key input signal and a right hand side input unit. A left hand side input unit for generating a key input signal, a position detection means for detecting the position of the operator's finger on each panel surface of the right hand side input unit and the left hand side input unit, and position detection Position information display unit for displaying the position information of the operator's fingers on each panel of the right hand side input unit and the left hand side input unit based on the signal from the means at a place different from the right hand side input unit and the left hand side input unit And.

In the above input device, the right hand side input unit in which the keys in charge with the right hand are arranged and the left hand side input unit in which the keys in charge with the left hand are arranged are independent, so that it matches the position of the operator's hand. Each input unit can be arranged. And since the position of the finger on the board surface of these input parts can be confirmed via a position information display part, each input part can also be arranged at a position where the operator cannot see the board surface.
When using a keyboard used for key input in a PC or a word processor, keys to be input by the right hand and the left hand in a commonly performed blind touch are determined. In the present invention, the “key in charge with the right hand” means a key input with the right hand as in the above-mentioned blind touch, and the “key in charge with the left hand” means a key input with the left hand. The input device of the present invention also includes a right-hand side input unit in which keys assigned to the left hand are also arranged and a left-hand side input unit in which keys assigned to the right hand are also arranged.

  The right-hand side input unit and the left-hand side input unit may be provided with a cover that covers the upper surface of each panel while keeping a space for the operator's fingers to enter. If it does so, things other than an operator's finger | toe will be mounted on the right hand side input part and the left hand side input part, and it can prevent that the key input contrary to the intention is made. The “thing other than the operator's fingers” includes, for example, a comforter that the operator can lie on his / her back and hang on the body. If the board surface of each input unit is covered with a cover, the comforter will not interfere with the movement of the operator's fingers even when the comforter is hung on the operator who is lying on the back, allowing accurate key input. .

  The upper surface of the cover is preferably a flat surface on which the mouse can be operated. For example, when a right hand side input unit and a left hand side input unit are arranged on the right hand side and the left hand side of an operator lying on the futon, respectively, and a computer is operated, a place for operating the mouse cannot be secured. A separate stand for operating the mouse may be provided, but this requires more space, and the right-hand side input unit and left-hand side input unit are located at different positions. It is not always possible to place the mouse at an easy position. Therefore, if the mouse can be operated on the right hand side input unit or the left hand side input unit, it is not necessary to provide a dedicated stand for operating the mouse, and the same as the right hand side input unit or the left hand side input unit. You can operate the mouse at the position. In the operation of the mouse, the comforter on the operator does not get in the way compared to the key input on the keyboard.

  An example of the position detection means is an imaging means that is provided on each of the covers of the right-hand side input unit and the left-hand side input unit and photographs each board surface, in which case the right-hand side input unit photographed by the imaging means and The image on the board surface of the left-hand side input unit is preferably displayed on the position information display unit. Then, the operator can check the position of his / her fingers and the key position on the surface of the right hand side input unit and the left hand side input unit via the position information display means. An input unit and a left-hand side input unit can be arranged. Further, if the position image pickup means is provided on the cover, the position detection means becomes compact.

  An example of such an image pickup means is composed of a plurality of mirrors arranged above the board surface and projecting different areas, and one image sensor that receives light from an image on the board surface by these mirrors. In this configuration, an optical element for forming image light from a plurality of mirrors on the imaging element may be provided between the mirror and the imaging element.

  Further, as another example of the position detection means, there can be mentioned one provided with a contact detection mechanism for detecting a contact of an operator's finger to each key and generating a contact signal. In addition, it is preferable to display the information of the key that is touched by the operator's finger according to the contact signal from the contact detection mechanism. The “key information” here is the positional relationship of the keys and information (for example, letters, numbers, symbols) input by the keys. As a preferred embodiment, the overall key arrangement in which the right-hand side input unit and the left-hand side input unit are combined with the position information display unit is virtually displayed in advance corresponding to the actual key arrangement (hereinafter referred to as the position information display unit). The key arrangement virtually displayed on the virtual keyboard is referred to as a virtual keyboard.) The key on the virtual keyboard corresponding to the key detected by the contact detection mechanism is discolored or emits light, and the finger is in contact with the operator. The key information is shown.

  An example of the contact detection mechanism is a touch sensor that is provided on the upper surface of each key and emits a contact signal when touched by an operator's finger.

  As another example of the contact detection mechanism, a contact signal transmission mechanism that is provided in each key and generates a contact signal when pressed down to a predetermined depth shallower than a depth at which a key input signal is generated can be exemplified. As the contact signal transmission mechanism, a mechanical interrupter that detects the depression of the input key by light, a magnetic sensor that magnetically detects the depression of the input key, and the like can be used in addition to the mechanical conduction by depressing the key.

  An information input display system of the present invention is connected to a monitor, a monitor support member that supports the monitor in front of an operator who is turned upside down, the input device of the present invention, the input device, and the monitor. And an information processing device that performs processing based on a key input signal from a key input signal transmission circuit and displays predetermined information on the monitor. That is, the information input display system of the present invention uses the input device of the present invention provided with a right hand side key input unit and a left hand side key input unit that are provided separately, and uses the input device of the present invention to lie on the back in a natural body posture. A right hand key input unit is disposed at the right hand position, and a left hand key input unit is disposed at the left hand position so that the information input display system can be operated in a natural posture. Since the position information display part that displays the position information of the fingers on the surface of the right-hand side key input part and the left-hand side key input part can be arranged at a position that falls within the operator's field of view, such as in the vicinity of the monitor, It is possible to check the position of the fingers and the key without deflecting, and even an operator who cannot perform a blind touch can be easily handled.

  A liquid crystal display of a notebook personal computer (hereinafter referred to as a notebook PC) can be used as the monitor of the information input display system, and the main body of the notebook PC can be used as the information processing apparatus. The liquid crystal display of the notebook PC is light, and the hard disk (HD), central processing unit (CPU), and the main body where the memory is consolidated are heavier. The structure of the support member that supports the is simplified. By using the main body of the notebook PC as an information processing apparatus, the overall system configuration can be simplified. As described above, if a normal notebook PC can be used, there is an advantage that it is not necessary to purchase a new dedicated monitor or computer.

  In this information input display system, the position information display unit provided in the input device may be a sub monitor provided separately from the monitor, or a partial area in the monitor of the information input display system is used. It may be a thing.

According to the input device and the information input display system of the present invention, the right hand side input unit in which the keys in charge with the right hand are arranged and the left hand side input unit in which the keys in charge with the left hand are arranged are independent and right side A position information display unit that displays the position information of fingers on the board of the input unit and the left hand side input unit at a position different from both input units is provided, so that the operator's field of view can be viewed without worrying about the operator's field of view. Each input unit can be arranged according to the position of the hand. Regardless of the position of both input units, the position of the fingers on the input panel can be confirmed via the position information display unit, so each input unit cannot be viewed by the operator. Can also be arranged. As a result, key input in an arbitrary posture becomes possible.
For example, the right-hand side input unit can be disposed at the position of the right hand of the operator in a lying state, and the left-hand side input unit can be disposed at the position of the left hand. Then, the monitor is placed in front of the operator who lies on his back, and the position information display unit is placed at a position that falls within the visual field of the operator, so that the operator can lie on his back and take a natural body posture. Key input can be performed easily without any change.

FIG. 1 is a block diagram schematically showing an example of an information input display system according to the present invention.
An input device 4 for key input by the operator 2 is connected to the information processing device 6. A monitor 8 that displays predetermined information is connected to the information processing apparatus 6. The monitor 8 is disposed in front of the operator 2.

  The input device 4 includes a right-hand side input unit 10a, a left-hand side input unit 10b, position detection means 12a and 12b provided in both the input units 10a and 10b, and a position information display unit 14.

  The right-hand side input unit 10a has a panel surface on which keys assigned to the operator 2's right hand are arranged, and is arranged at the position of the operator's 2 right hand. The left hand side input unit 10b has a panel surface on which keys assigned to the left hand of the operator 2 are arranged, and is arranged at the position of the left hand of the operator. The right hand side input unit 10a and the left hand side input unit 10b are configured to transmit a key input signal corresponding to the key to the information processing device 6 when any key is pressed down to a predetermined depth. The information processing apparatus 6 performs processing based on the key input signals of the input units 10a and 10b and displays information related to the processing on the monitor 8.

  Position detecting means 12a and 12b provided in the right hand side input unit 10a and the left hand side input unit 10b detect the position of the finger of the operator 2 arranged on the board surface of both the input units 10a and 10b and display position information. The position information signal is transmitted to the unit 14. The position information display unit 14 displays the position information of the fingers in the field of view of the operator 2 based on the position information signals from the position detecting means 12a and 12b. Since the position information display unit 14 is arranged in the visual field of the operator 2 such as the vicinity of the monitor 8 or a part of the monitor 8, the operator 2 does not look at the board surface of each input unit 10a, 10b. The position of his / her finger on the board of the right hand side input unit 10a and the left hand side input unit 10b and the position of the key to be input can be confirmed via the position information display unit 14 with little gaze from the monitor 8. .

Next, a more specific embodiment of the information input display system of the present invention will be described. 2A and 2B are diagrams illustrating an information input display system according to an embodiment together with an operator, in which FIG. 2A is a side view seen from the right hand side of the operator, and FIG. 2B is a view seen from below the operator.
This embodiment shows an example in which a key input is performed with the operator 2 lying on his back and a notebook PC 16 is used as a monitor and an information processing apparatus. The liquid crystal display 16a of the notebook PC 16 realizes the monitor 8 in FIG. 1, and the main body portion 16b having a CPU and HD realizes the information processing apparatus 6.

  The support member that supports the notebook PC 16 is disposed on the head of the operator 2 in a supine state. The notebook PC 16 has a main body portion 16b fixed to a holding portion 22 rotatably supported by a rotating fixture 20 on an upper end of a support column 18 extending vertically upward from a base of a supporting member by fixing tools 24a and 24b. The position of the column 18 and the angle of the holding portion 22 by the rotary fixture 20 are adjusted so that the screen of the liquid crystal display 16a comes to the front of the operator 2 when the notebook PC 16 is opened. Note that the operator 2 can also adjust the angle of the notebook PC 16 so that the screen of the liquid crystal display 16a can be easily seen. Further, since the holding portion 22 is rotatably supported by the support column 18, the notebook PC 16 can be stored by folding the holding portion 22 to the support column 18 side when the notebook PC 16 is not used.

  Since the screen display of the liquid crystal display 16a of the notebook PC 16 arranged in this way is reversed from the normal screen display as shown in FIG. 2B, the screen display is displayed on the notebook PC 16. Incorporate software to reverse.

  A right-hand side input unit 10a in which keys assigned to the right hand are arranged at the position of the right hand when the operator 2 is in a natural state is arranged with its board face up. Although not shown in the drawing, as with the right hand side, the left hand side input unit 10b in which keys assigned to the left hand are arranged at the position of the left hand of the operator 2 is arranged with the board face upward. The right hand side input unit 10a and the left hand side input unit 10b are connected to, for example, a USB (Universal Serial Bus) terminal of the notebook PC 16 via cables 26a and 26b.

As shown in FIG. 3, the right-hand side input unit 10a and the left-hand side input unit 10b are a key side (right-hand side input unit 10a) for inputting with the right hand a board surface having the same key layout as a normal keyboard and a key for inputting with the left hand. It is divided into the left side (left hand side input unit 10b).
In addition, all the keys arranged on the board surface of a normal keyboard may be arranged on the board surface of the right hand side input unit 10a, the left hand side input unit 10b, or both the input units 10a and 10b. Then, the key input operation can be performed with only the right hand or only the left hand.

  Covers 13a and 13b are provided on the board surfaces 11a and 11b of the input units 10a and 10b, respectively, so as to cover the operator 2 with fingers and the space for operation. By providing the covers 13a and 13b, for example, even when a comforter is placed on the input portions 10a and 10b, accurate key input is possible without obstructing the operation of the fingers of the operator 2. become.

  The upper surfaces of the covers 13a and 13b are flat surfaces. Therefore, although not shown, the mouse can be placed on the cover 13a or 13b for operation. When a PC is operated with the mouse lying on its back on the futon, a place for operating the mouse is required. Key input can be realized by the right-hand side input unit 10a and the left-hand side input unit 10b. However, when a mouse is used, a separate place is required. In such a case, the mouse can be operated at the same position as the key input by using the upper surfaces of the covers 13a and 13b.

  In FIG. 2, the right hand side input unit 10 a and the left hand side input unit 10 b are arranged on the left and right sides of the operator 2 body with the board surface facing upward, but by providing the covers 13 a and 13 b. For example, as shown in FIG. 7, the covers 13 a and 13 b can be used as support bases for the input units 10 a and 10 b and can be arranged on the left and right sides of the head of the operator 2 with the surface facing downward.

  The right hand side input unit 10a and the left hand side input unit 10b are provided with position detection means for detecting the position of the finger of the operator 2 on each of the board surfaces 11a and 11b, and the position of the finger obtained by the position detection means. Information is displayed on the sub-monitor 14a attached to the end of the liquid crystal display 16a by the attachment member 28. The sub monitor 14a implements the position information display unit 14 in FIG. The position detection means of the right-hand side input unit 10a and the left-hand side input unit 10b and the sub monitor 14a may be configured to transmit and receive signals via cables, or may be configured to transmit and receive signals wirelessly. Good.

The following is mentioned as a structure of the position detection means provided in the right hand side input part 10a and the left hand side input part 10b.
As an example, the board surfaces 11a and 11b of the input units 10a and 10b are photographed from above the fingers of the operator. Specifically, as shown in FIG. 4, it can be realized by providing a small camera 28 such as a CCD (Charge Coupled Device) camera and a plurality of mirrors 30 arranged in the key arrangement direction inside the cover 13a of the input unit 10a. . The plurality of mirrors 30 are arranged so as to cover the entire area of the board surface 11a. Since each mirror 30 projects a predetermined area toward the small camera 28, an image of the entire area of the board surface 11 can be taken with the small camera 28. Note that the configuration of the position detecting means of the right hand side input unit 10a and the left hand side input unit 10b is the same, and only the right hand side input unit 10a is shown in FIG.

  In the case where the position detection means is configured to use the image pickup means as shown in FIG. 4, it is preferable that the photographed image is displayed as the position information of the fingers displayed on the sub monitor 14a. Then, the operator 2 can view his / her fingers on the board surfaces 11a and 11b of the input units 10a and 10b in the same manner as viewing the keyboard board surface through the sub monitor 14a attached in the vicinity of the liquid crystal display 16a. And the position of the key you want to enter. Therefore, since it is not necessary to deflect the line of sight from the screen of the liquid crystal display 16a, key input with an easy posture is possible.

Another example of the position detection means is to detect a key touched by a finger.
As one specific example, a touch sensor 34 is attached to the upper surface of the key 32 as shown in FIG. Providing a touch sensor on the upper surface of the key is a well-known technique as disclosed in Patent Document 1. The touch sensor 34 is configured to detect the contact of the finger 2a and transmit a contact signal corresponding to the key 32 to the sub monitor 14a. In this case, the key layout pattern in which the board surfaces 11a and 11b of both the input units 10a and 10b are combined is displayed in advance on the sub-monitor 14a, and the keys on the key layout pattern corresponding to the detected touch sensor 34 change color, emit light, etc. Thus, it is preferable to be shown to the operator 2. Then, the operator 2 can easily recognize which key in the key arrangement pattern of the sub-monitor 14a is touched by his / her finger, and can easily find out where the key to be input is. . Even with this method, it is not necessary to deflect the line of sight from the screen of the liquid crystal display 16a, so that key input with an easy posture is possible.

  Further, as a method for detecting a key touched by a finger and replacing the touch sensor 34 described above, there is a structure in which a touch of a finger is detected by lightly pressing the key and key input is performed by further pressing the key. It is done. 6A and 6B are cross-sectional views showing an example of the structure. FIG. 6A shows a normal state, FIG. 6B shows a primary push, and FIG. 6C shows a secondary push.

  The bottom of each key 32 fitted in the opening of the keyboard casing 33 is supported by a silicone spring 36. The silicone spring 36 is placed on the multilayer wiring layer 38, and a primary pushing portion 36a and a secondary pushing portion 26b, which are convex portions protruding downward, are formed therein. The secondary push portion 36b is formed at the highest position in the center of the silicone spring 36, and the primary push portion 36a is formed at a position lower than the secondary push portion 36b.

The multilayer wiring layer 38 includes an upper energizing plate 40 and a lower energizing plate 42 and an insulating layer 44 between the energizing plates 40 and 42. At a position corresponding to the primary push portion 36a of the multilayer wiring layer 38, there are provided a primary conduction portion 38a and a secondary conduction portion 38b having a space between the upper and lower energization plates 40, 42. The primary conduction part 38a and the secondary conduction part 38b are brought into contact with each other and the conduction plates 40 and 42 are brought into conduction when the primary pushing part 36a or the secondary pushing part 36b descends and the upper conduction plate 40 is pushed downward. ing.
The upper energizing plate 40 and the lower energizing plate 42 are electrically connected to each other when the energizing plates 40 and 42 are in contact with each other at the primary conducting portion 38a and transmit a contact signal corresponding to the key; A key input signal oscillating circuit is formed which conducts when both energizing plates 40 and 42 come into contact with each other in the portion 38a and transmits a key input signal corresponding to the key. The contact signal is transmitted to the sub monitor 14a, and the key input signal is transmitted to the notebook PC main body 16a.

  According to this configuration, as shown in FIG. 6B, when the key 32 is lightly pressed, the primary push portion 36 a of the silicone spring 36 comes into contact with the upper energizing plate 40 first and the upper energizing plate 40. Is pushed downward and the upper and lower energizing plates 40 and 42 are brought into contact with each other in the primary conduction portion 38a, whereby the contact signal transmission circuit is conducted and a contact signal is transmitted. In this state, since the secondary push portion 36b is not in contact with the upper energization plate 40, the key input signal transmission circuit is not conductive. As shown in (C), when the key 32 is further pushed in, the secondary pushing portion 36b comes into contact with the upper energizing plate 40 and the upper and lower energizing plates 40 and 42 are brought into contact with each other in the secondary conducting portion 38b. The key input signal transmission circuit is turned on and a key input signal is transmitted.

  Also in this example, as in the example of FIG. 5, a key arrangement pattern in which the board surfaces 11a and 11b of both the input portions 10a and 10b are displayed in advance on the sub monitor 14a, and in accordance with the contact signal from the contact signal transmission circuit. It is preferable that the key on the key arrangement pattern is indicated to the operator 2 by discoloration or light emission.

  2 to 6, the information processing apparatus 6 and the monitor 8 in FIG. 1 are realized by the notebook PC 16, but the present invention is not limited to this, and a normal It can also be realized by a PC display and a main body.

  Moreover, although the sub monitor 14a was demonstrated as the positional information display part 14 in the Example demonstrated using FIGS. 2-6, this invention is not limited to this, A part of screen of the liquid crystal display 16a is set by software. The position information of fingers on the board surfaces 11a and 11b of both the input units 10a and 10b may be displayed using the area. In that case, signals from the position information detection means provided in both the input sections 10a and 10b are transmitted to the notebook PC main body 16b via the cables 26a and 26, and the signal processing is performed in the notebook PC main body 16b to perform liquid crystal display. The position information is displayed on the screen of the display 16a. In FIG. 1, the position information display unit 14 is in the monitor 8, and the position detection units 12 a and 12 b are connected to the information processing device 6 together with both the input units 10 a and 10 b.

  In the embodiment of FIG. 2, the embodiment of the information input display system capable of performing key input with the operator 2 lying on the back is shown. However, the input device 4 (FIG. 1) of the present invention is operated by the operation. The person 2 can perform key input in an arbitrary posture, and is not limited to use in a posture on the back.
