Description

  The present invention mainly relates to an input device for a computer, and more particularly, to a finger-mounted input device and a program for inputting data and commands by generating a regular contact position pattern on a touch panel by being mounted on a finger.

  In recent years, contact position detection devices (hereinafter collectively referred to as touch panels) that are operated by touching with a finger or a stylus such as a touch pad, a touch panel, and a touch display have become widespread. In such a device, the input of the coordinates of the point where the touch panel surface is touched with a finger or an instrument is fundamental. In the present invention, a new type of input device to be worn on a finger has been devised as an input device for a touch panel that replaces a conventional stylus. With the conventional stylus, the coordinate series was input by hand, so the coordinate series fluctuated irregularly, and unless combined with a special handwritten character recognition method, characters and commands could not be input, and input errors could occur. There were many. On the other hand, this input device can generate a regular coordinate series with little fluctuation, and can accurately input characters, commands, and the like by a simple collation process. In addition, a tactile feedback mechanism is introduced so that the operator can clearly grasp the contact state with the touch panel through the tactile sense. Furthermore, if such a device is worn on a finger, the freedom of the finger is taken away and a strong sense of restraint has been a problem.In the present invention, this device is placed on the finger so as not to give a sense of restraint. The contact part (protrusion part) with the touch panel is supported at the tip of the finger through the frame part extending from the fixed part to be fixed to the finger tip through the side or upper surface of the finger. The feeling of restraint is alleviated by opening the ventral side of the finger that is sometimes used. In the present invention, in addition to the finger-mounted input device described above, a program is provided for associating a coordinate series generated when it touches the touch panel with data or commands. In addition to simply using the contact position, a rolling member that rolls in contact with the touch panel is supported at the tip of the finger by the frame, and the rolling direction detected when the rolling element is rolled on the touch panel. And a finger-mounted input device and a program for determining information to be input using the amount of rolling.

  A common input device currently used for inputting coordinates to a touch panel is a pen-like instrument called a stylus. However, once the stylus is held, other operations such as pressing a button become impossible. In addition, when inputting coordinates by hand with a stylus, the coordinate series to be input fluctuates irregularly. Therefore, a special recognition developed with character recognition technology and the like to interpret the operator's intention while absorbing the fluctuation. However, it was a problem that many interpretation errors occurred even if such a device was used.

  Therefore, in the present invention, in order to avoid the restraint caused by the finger having a specific instrument and to eliminate the inaccuracy caused by handwriting input with the finger, the instrument for inputting the coordinate series to the touchpad is touched with an object. It is designed to be worn on the finger while avoiding the lower surface of the finger used when picking or picking, and has a function to accurately generate a coordinate series of contact positions with a specific positional relationship on the touch panel. A finger-worn input device and a program are provided that have a mechanism for generating tactile feedback to stimulate the tactile sensation of the operator's finger so that the operator can grasp through tactile sense whether or not the user has been correctly generated.

Patent documents related to the present invention are shown below.
JP 2003-208262 A JP 2001-306238 A JP 2004-46684 A JP 2003-208262 A JP 2003-167669 A JP 2005-293512 A

  Patent Documents 1 and 2 show a method of inputting data and commands by an operation of rolling a roller-shaped rolling element on a touch panel. All of them relate to the present invention in that a regular coordinate series is generated by using a roller-shaped special instrument. Also in Patent Document 3, a regular contact point series is generated using an instrument, but the target is not a touch panel but an electrical contact of a switch.

  Next, Patent Documents 4 and 5 generate a coordinate series in a special form on the touch panel and transmit a specific command to the computer in the special form, but this is a tactile sense. It is not intended to improve operability in combination with stimuli. Patent Document 6 is an invention related to a finger-mounted input device, but is not an invention related to an instrument that generates a regular coordinate series on a touch panel.

  The present invention has been devised in view of the above situation, and the touch position detection function of the touch panel is versatile by interposing a special instrument between the finger and the touch panel without restricting the degree of freedom of the finger. An object is to provide a finger-mounted input device and a program for applying to a multi-function and allowing an operator to grasp an input state through a tactile sense.

  The finger-mounted input device according to the first aspect of the present invention is used together with a touch panel having a function of detecting the position of a contact point or a pressure point on the surface thereof. This device is a finger-mounted input device that is used by attaching it to an operator's finger, but its frame part is placed on the side or upper surface of the finger from the finger fixing part for fixing the device to the finger at the time of wearing. Traces up to the tip of the finger, and supports the protrusion that contacts the touch panel at the tip of the finger. By doing so, the frame part does not come to the lower surface (abdomen) of the finger, and the lower surface of the finger used for picking or touching an object is exposed without being blocked by the frame part. ing. As described above, since the lower surface of the finger is not covered with the frame portion, it is one of the features of the present invention that the degree of freedom of the finger is not restricted even when the device is mounted.

  According to a second aspect of the present invention, the above-described protrusion is configured as follows. That is, the contact protrusions that come into contact with the touch panel and the stimulus protrusions that stimulate the finger are constituent elements of the protrusion, and when the contact protrusion touches the touch panel, the stimulus protrusion moves to the finger side to stimulate the sense of touch of the finger It is configured to do. The contact protrusion and the stimulating protrusion may be integrated, and in this case, when one end of the touch protrusion touches the touch panel, the other end moves to the finger side and the finger touch may be stimulated. it can. Through this stimulation, the operator can confirm that the protrusions have surely touched the touch panel and that other parts have not touched the touch panel by mistake. Further, a plurality of contact protrusions and stimulation protrusions may be provided, and various mechanisms can be interposed to link the operations of both.

  According to a third aspect of the present invention, there is provided a finger-mounted input device in which the entire frame part or a part thereof is made of a material that is rich in flexibility and elasticity. This material is effective even if it is partially introduced into a place that supports the above-described protrusions or their constituent contact protrusions and stimulation protrusions (hereinafter simply referred to as protrusions for simplicity). is there. Further, when a plurality of contact protrusions and stimulation protrusions are introduced as described later, it is necessary to individually support them with a material having flexibility or elasticity so that they can move independently. In this case, if the entire frame portion is made of a material having flexibility or elasticity, it is not preferable because all the protrusions move simultaneously. Therefore, it is advisable to make appropriate cuts in the material so that each protrusion moves separately. If the frame part and the protrusion can be configured integrally while paying attention to the above points, a mechanism for moving the protrusion relative to the frame part becomes unnecessary, which simplifies the configuration of the device and reduces the manufacturing cost. There is an advantage that can be lowered. In this way, while reducing costs by making it one piece, due to the flexibility and elasticity of the material, when one end of the protrusion touches the touch panel, the reaction causes the frame part or part of it to deform and the other end stimulates the tactile sense of the finger To move.

  The finger-mounted input device according to claim 4 of the present invention is configured such that the protrusion moves relative to the frame portion. For example, in the configuration shown in FIG. 1 later, the contact protrusion and the stimulation protrusion are integrated and slide in the hole of the holding portion supported by the frame. This sliding movement is a relative movement with respect to the frame portion. Providing such a mechanism increases the manufacturing cost compared to the case of the above-described integrated configuration, but even a delicate contact between the protrusion and the touch panel is reliably transmitted to the tactile sense of the finger, so that a device that can grasp the contact more sensitively can be configured. .

  A finger-worn input device according to claim 5 of the present invention comprises a plurality of the above-mentioned contact projections and stimulation projections, and each of the stimulation projections moves independently to stimulate the sense of touch of the finger. It is configured. The protrusions having these protrusions are supported by the above-described frame part, and a plurality of contact protrusions contact the touch panel one after another by the movement of the finger. The order of this contact varies depending on the form of finger movement. If the contact of each contact protrusion on the touch panel is linked to the movement of a specific stimulus protrusion, it can be distinguished through stimulation from the stimulus protrusion which contact protrusion is in contact with the touch panel. become. As each contact projection touches the touch panel, the corresponding stimulus projection stimulates the tactile sensation of the finger to notify the operator that the projection has touched, so the operator can exercise using this stimulus as a clue. The order of contact of the contact protrusions with the touch panel can be correctly controlled. In this way, if the operator appropriately moves and contacts the contact protrusions at a predetermined position in a predetermined order, the positional relationship of the contact coordinate points also changes because the positional relationship of the protrusions is fixed. However, the relationship is precisely defined, and the coordinate series of the contact position detected on the touch panel side is also regular, and the information to be input can be specified accurately. On the other hand, when inputting coordinates by hand with a conventional stylus, the coordinate series of contact positions on the touch panel changes every time an input operation is performed. A special device to absorb is required. In addition, erroneous input is generated for fluctuations that cannot be absorbed.

  According to a sixth aspect of the present invention, there is provided a finger-mounted input device in which a member called a rolling element is provided on the above-described protrusion. The motion that rolls and moves on the touch panel while touching the touch panel is referred to as rolling. An object that rolls and moves is called a rolling element. First, the operator brings the rolling element into contact with the touch panel and starts rolling the rolling element to input information. There are various types of rolling elements such as a sphere and a rugby ball. The rolling element stimulates the tactile sensation of the finger when rolling and notifies the operator of the rolling direction and the amount of rolling, so the operator adjusts the movement using this stimulus as a clue, and correctly controls the rolling direction and the amount of rolling. can do. In addition, when inputting coordinates with a conventional stylus, the tremor of the finger was easily transmitted to the tip of the stylus, and the coordinate series was often disturbed. However, when inputting coordinates while rolling the rolling element, the tremor was reduced and it was accurate. It becomes possible to input a coordinate series.

  The program according to claim 7 of the present invention is a program used in combination with the finger-mounted input device described above. In this program, first, at the time of registration or design, a coordinate series corresponding to each operation of the operator is registered, and data and commands corresponding to the registered coordinate series are defined to form a table or the like. That is, when the operator operates the contact projection to contact the touch panel in a predetermined order at the time of registration or design, the coordinate series of the contact position detected on the touch pad side is registered in advance. A correspondence relationship between the registered coordinate series and input data or commands is defined in advance. Then, this time, when the operator performs an input operation, the coordinate sequence of the contact position detected at the time of input and the coordinate sequence registered in advance are compared and matched, and the corresponding coordinate sequence can be matched. Enter data or commands.

  A program according to an eighth aspect of the present invention is a program used in combination with the finger-mounted input device described in the sixth aspect. In this program, first, a menu is pop-up displayed on the screen based on which area includes a position where the rolling element contacts in a plurality of areas provided in advance on the touch panel. When the rolling element moves while touching on the touch panel, an item in the pop-up menu is selected as follows. That is, using the contact position of the rolling element as the first touch panel as a reference point, obtain the direction and amount of movement while the rolling element is in contact, and select the item at the position corresponding to this direction and amount in the pop-up menu To do.

  The above finger-fitted input devices can be prevented from being lost if they are connected to a mobile phone, PDA, etc. by a strap, and if they are lightweight devices such as mobile phones, they can be connected to the fingers through the strap and this device. It is also effective in preventing falls. When the finger-mounted input device is mounted on a finger, a part of the strap may be used as a band so that the finger-mounted input device is fastened to the finger.

  In the present invention, a mechanism for inputting the contact relationship between the protrusion and the touch panel to the device and feeding back to the tactile sensation of the finger is introduced, and this mechanism is supported by a frame arranged so as not to restrain the degree of freedom of the finger. This is a program that recognizes the coordinate series and allows you to input the coordinate information accurately and comfortably while clearly grasping the contact position information of multiple protrusions without giving the operator a sense of binding. In combination with the touch panel, the touch panel contact position detection function can be used for multiple purposes.

  FIG. 1 shows an example of a finger-mounted input device according to an embodiment of the present invention. FIG. 2 shows an example in which this embodiment is worn on a finger. 1A and 2A are top views of the finger-mounted input device 50, and FIG. FIG. 2C shows a state in which the touch panel 6 is touched by the finger-mounted input device 50 of the present embodiment. In FIG. 1A, the shaft 52 of the contact projection 1 passes through a hole provided in the holding portion 2 and is integrated with a stimulation projection 51 provided on the opposite side. And these all comprise the projection part. This protruding portion is connected to the finger fixing portion 8 through the frame portion 3. The finger fixing part 8 is provided with a hole 9 through which the strap passes. As shown in FIG. 2, the strap 4 is used like a band and passed through the hole 9 of the finger fixing part, and then the finger is wound around the buckle. Fix through 5. Also, the other end of the strap can be connected to a mobile phone, a PDA or the like, so that the fall of these devices can be supported and prevented with a finger. As shown in FIG. 2, since the frame portion 3 is mounted so as to contact the side surface of the finger, the opening portion 7 surrounded by the frame portion is widened as much as possible so as to expose the lower surface of the finger as widely as possible. . Since the shaft 52 can slide and move through a hole provided in the holding portion 2, when the contact projection 1 is pushed in contact with the touch panel, the stimulation projection 51 at the opposite end of the shaft 52 pops out toward the finger. Will stimulate the sense of touch of the finger.

  FIG. 3 shows an example different from FIG. 1 of the finger-mounted input device 50 according to the embodiment of the present invention. (A) shows a top view, (b) shows a side view, and (c) shows how the touch panel is touched. The structure of the protrusion in this example is the same as in FIG. 1, and the principle that the stimulating protrusion stimulates the finger by the reaction when the contact protrusion contacts the touch panel is the same. This protrusion is connected to the finger fixing portion 53 by a frame portion 54 provided along the upper surface of the finger. Since the frame portion 54 is provided on the upper surface side of the finger, the lower surface of the finger is completely open as indicated by reference numeral 7, and no restriction is generated when touching an object with the lower surface of the finger. . The strap 4 is fastened so as not to be loosened through the buckle 5 after turning around the finger through the hole of the finger fixing portion 53 and fastening the finger fixing portion to the finger.

  FIG. 4 shows an embodiment different from any of the above-described examples of the finger-mounted input device 50 according to the embodiment of the present invention. (A) is a top view and (b) is a side view. In this example, the contact protrusion and the stimulus protrusion are integrated to form a protrusion, which is indicated by reference numeral 10. This protrusion is integrated with the frame portion 12 and the finger fixing portion 11. The frame portion 12 is made of a material that is elastic and easily deformed. When one end of the projection portion 10 comes into contact with the touch panel, the frame portion is deformed, so that the projection portion moves to the finger side, and the other projection portion. The edge stimulates the tactile sensation of the finger. Since the frame portion 12 is mounted along the side surface on one side of the finger, the lower surface of the finger is exposed widely. Also in this example, the finger fixing portion 8 is provided with a hole through which the strap is passed, and the finger to be placed on the finger fixing portion is fixed using the strap like a band as in the example of FIG.

  FIG. 5 shows an operation example of a structure in which the protrusion for stimulation stimulates the tactile sensation of the finger when the contact protrusion is in contact with the structure of the protrusion and the touch panel in the finger-mounted input device 50 according to the embodiment of the present invention. . In any of FIGS. 5A and 5B, the structure of the protrusion is the same as that in FIG. 1, and the cross section of the protrusion is shown for easy understanding of the operation. FIGS. 5A and 5B show an example in which a pair of contact protrusions and stimulation protrusions are provided. In (a), the contact protrusion is not touching the touch panel, so the contact protrusion is not pushed in and the stimulating protrusion is not stimulating the finger, but in (b) the contact protrusion is pushed in, You can see how the stimulating projections stimulate the fingers. FIGS. 5C and 5D show an example in which three pairs of contact protrusions and stimulation protrusions are provided. In (c), since none of the contact protrusions is in contact with the touch panel, none of the contact protrusions is pushed in, and none of the stimulation protrusions 1a, 1b, 1c stimulates the finger. ), As a result of the finger tilting and touching the touch panel, it can be seen that the contact projection on the contact side is pushed in and the stimulation projection 1a stimulates the finger. The operator can know that only the contact protrusion at a position corresponding to 1a has touched the touch panel because only 1a of the three stimulation protrusions stimulates the sense of touch of the finger. If there is no mechanism to stimulate the sense of touch like this, the operator lowered his finger toward the touch panel, and when touching the touch, the part of the protrusion touched the touch panel. I don't know where it is. On the other hand, in the examples of FIGS. 5C and 5D, for example, when the three contact protrusions are hit against the touch panel one after another while twisting a finger on the touch panel, the contact protrusions corresponding to each other are dealt with. The stimulating protrusions that stimulate the finger one after another. Through this stimulation, the operator can know that the three contact protrusions have surely contacted the touch panel in this order. At this time, since the distance between the touch points on the touch panel is accurately determined by the distance between the three contact protrusions, a regular coordinate series is input. When collating, the work becomes easier and the accuracy is higher. In FIG. 6, the coordinate points detected by the touch panel when the finger is twisted on the touch panel 6 and the contact protrusions are successively hit against the touch panel are indicated by black circles. First, in (a), the center projection touches and the point indicated by the symbol P1 is the coordinate detected as the contact point. In (b), as a result of twisting the finger, the two left protrusions are in contact with the touch panel at the same time. When a resistive film type touch panel is used, the coordinates detected when the two points are in contact at the same time become the center of gravity of the two contact points, and therefore the point indicated by the symbol P2 is detected. In addition, as a result of further twisting in (c), only the left end protrusion comes into contact with the touch panel, so that the point indicated by the symbol P3 becomes the coordinates detected as the contact point.

  FIG. 7 shows various methods for moving the contact protrusion and the stimulation protrusion in the protrusion. In FIG. 7A, the ball 22 freely rotates in the receiving portion 23 of the ball-type joint, and the posture of the column 21b fixed to the ball 22 can be freely changed. As a result, when the finger is moved sideways while pressing one end of 21b against the touch panel 6, one end of 21a, which is a projection for contact as shown in FIG. The end on the finger side of 21c, which is a protrusion, protrudes to stimulate the finger. Further, in FIG. 7C, a rolling element 32 (ball that rolls on the touch panel), which will be described later, is introduced. By changing the posture of the protruding part like a seesaw with the rolling element 32 as a fulcrum, a contact protrusion The side which hits a touch panel among 31a and 31c with which the protrusion for stimulation is united moves in reaction and stimulates a finger | toe.

  FIG. 8 shows a program for determining data and commands based on a coordinate sequence obtained by moving a finger on the touch panel and bringing the contact protrusions into contact with the touch panel in a series of orders based on the principle described above. Show the procedure. This program operates on a computer device such as a general-purpose personal computer that inputs data from the touch panel and executes various arithmetic processes, or a control device built in the computer.

  First, at the time of design or pre-registration, the “correspondence table of coordinate series, data, command (command)” (S2) in the drawing is stored in advance in the computer device. When the operator generates a coordinate series by an operation on the touch panel (S1), the computer device collates with the coordinate series in this correspondence table (S3), and the data or command (command) associated with the matched coordinate series. ) Is entered or executed (S4). Until they match, the coordinate series in the table are taken out one after another (S2), and collation is repeated (S3). As a result, if any coordinate series does not match, an error message is displayed or nothing is executed. Quit without

  FIG. 9 shows an example in which rolling elements 42 are provided on the protrusions of the finger-mounted input device 50 according to the embodiment of the present invention. The rolling element in this case is a sphere made of a non-slip material such as rubber, and is rolled between the finger and the touch panel 6 when the finger moves. In FIG. 9A, reference numerals 41a and 41b denote frame portions. In this embodiment, rolling elements corresponding to the projection portions are attached to the frame portion via a spring 43 so as to be rotatable and translatable. For example, as shown in FIG. 9B, when the finger is moved to the right, the rolling element rolls on the touch panel and moves to the right. However, since the moving distance is half of the moving distance of the finger, the spring does not move as shown in the figure. Respond to differences in travel distance by expanding and contracting. Further, as shown in FIG. 9C, when the finger is moved forward, the distance that the rolling element 42 rolls and moves is half of the movement distance of the finger, so that the spring 43 extends as shown in the figure. When rolling elements are introduced into the protrusions, the touch position of the touch panel can be moved smoothly through the rolling of the rolling elements in this way, and the amount and direction of movement can be easily grasped through the feeling of rolling felt by the sense of touch of a finger. It is.

  FIG. 10 shows menu item selection for the finger-mounted input device 50 described with reference to FIG. 9 through the position PA where the rolling element contacts on the touch panel and the direction D that rolls while touching from the contact point and the amount M of movement. The operation procedure of the program that performs is described. The computer device first determines in which area PA (S7) is included in the contact area (S8) for selecting a pre-registered menu (S9), and if there is an included area. Pops up a menu corresponding to the area and displays it on the display screen (S10). If there is no area including PA at this time, nothing is executed and the process waits until the next contact position coordinate PA is given (S8). When there is an area including PA and the touching point moves while the rolling element is in contact with the touch panel and the contact point moves, the movement direction D and the movement amount M (S11) are obtained using the position of the PA as a reference point. Based on and M, an item in the pop-up menu is selected and highlighted (S12). This operation is continued as long as the rolling element keeps touching the touch panel, but data corresponding to the item selected (highlighted) at the moment of separation (S13) is input or a command is executed. (S14).

  As described above, according to the present embodiment, it is possible to input data to a device such as a computer device and feed back to the tactile sensation of a finger by the contact relationship between the protrusion and the touch panel. This makes it possible to input the coordinate information accurately and comfortably while clearly grasping the contact position information of the plurality of protrusions without giving the operator a sense of binding, in combination with a computer program that recognizes the coordinate series, It is possible to use the touch panel touch position detection function for multiple purposes and functions.
