[Configuration of tactile information display device]
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
The configuration of the tactile information display device will be described with reference to FIG. FIG. 1 is a block diagram of a tactile information display device according to an embodiment of the present invention. The tactile information display device 1 includes a control unit 10 and a tactile display 20 in order to realize each function described later.

  The tactile display 20 uses display target information including attribute information indicating an arbitrary attribute of the display target to drive the pins 24 arranged on the plane of the display unit 23 up and down to support them at a predetermined height. The display object is tactilely displayed, and includes, for example, a pin driving unit 21 and a display unit 23.

  The display means 23 includes a pin 24 that is supported and driven by the pin driving means 21. For example, the display means 23 has a rectangular shape in which pins 24 are arranged at regular intervals in the vertical and horizontal directions. The pin 24 is driven up and down by a pin driving means 21 to be described later, and is supported in a state where its tip protrudes from the plane of the display means 23 by a predetermined height.

The details of the display means will be described below with reference to FIG. 2A and 2B are diagrams for explaining the display means of FIG. 1, FIG. 2A is a diagram for explaining a tip shape of a pin, and FIG. 2B is a top view of a display screen. Note that the tip shape pin 1 (pin 24a) shown on the left side of FIG. 2A is indicated by a white circle in FIG. 2B, and the tip shape pin 2 (pin 24b) shown on the right side of FIG. This is indicated by a black circle in FIG.
Hereinafter, when the tip shape of the pin is not specified, it is simply referred to as the pin 24. Further, the pin 24a is used when describing the pin 24 having a smooth tip shape, and the pin 24b is used when explaining the pin 24 having a sharp tip shape.

  The pin 24 has an arbitrary tip shape. For example, as shown on the left side of FIG. 2A, the pin 24a has a smooth tip shape such as a hemispherical shape, a semi-elliptical sphere shape, and a cylindrical shape. 2A, the pin 24b may have a pointed tip shape such as a conical shape, a triangular pyramid shape, or a quadrangular pyramid shape. Thereby, the tactile information display device 1 can give the user different tactile sensations such as a smooth, rough, and sharp display target according to the tip shape of the pin 24.

As shown in FIG. 2 (b), the display means 23 may be arranged with pins 24a and 24b having different tip shapes alternately. Here, in the display means 23, the pins 24a are arranged in a vertical row, and the pins 24b are arranged in a vertical row in a row adjacent to the pins 24a. Further, the display unit 23 may be arranged such that the pins 24a are arranged in a horizontal row and the pins 24b are arranged in a horizontal row in a row adjacent to the pins 24a (not shown). Furthermore, the display unit 23 may arrange the pins 24a and 24b so that the pins 24b are adjacent to the top, bottom, left, and right of the pin 24a.
Needless to say, the display unit 23 may include a plurality of pins 24a or 24b having the same tip shape (not shown).

Hereinafter, returning to FIG. 1, the description of the configuration of the tactile information display device will be continued.
The pin driving means 21 supports the pin 24 at the height of the pin 24 calculated by the height calculating means 11 based on the control signal output from the control means 10 and uses the driving force calculated by the generated force calculating means 12. The pin 24 is driven (moved up and down) in the vertical direction. As the pin driving means 21, for example, there is one that drives the pin 24 by utilizing deformation of a piezoelectric element. In this case, since the time response of the piezoelectric element is good, it is suitable for controlling the pin 24 by a time pattern to be described later. Further, as the pin driving means 21, there is one that drives the pin 24 by a linear motor using a piezoelectric element.

  Moreover, as the pin drive means 21, there exist some which drive the pin 24 with the actuator which displaces an iron piece with the electromagnetic force which generate | occur | produces with a coil, such as a solenoid and a linear motor, for example. In this case, since the generated torque can be easily controlled by controlling the current flowing through the coil, it is suitable for controlling the generated force described later. The generated force corresponds to the driving force described in the claims.

  Further, as the pin driving means 21, for example, there is one that converts the rotational motion of the rotary motor into a translational motion by a mechanism such as a rack and pinion, a foam gear, a crank, etc., and drives the pin 24. Examples of the rotary motor include a DC motor, an induction motor, a synchronous motor, a servo motor, and a stepping motor. In particular, when a DC motor, an induction motor, or a servo motor is used as the rotary motor, the generated torque can be easily controlled, which is suitable for controlling the generated force. Further, when a servo motor or a stepping motor is used as the rotary motor, the rotation angle can be easily controlled, which is suitable for controlling the height of the pin 24. Further, when the crank mechanism is used, the time for raising and lowering the pin 24 can be easily changed by controlling the rotational angular velocity of the rotary motor, which is suitable for controlling the pin 24 by a time pattern.

  In addition, the pin driving means 21 can finely control the height of the pin 24 by using a displacement sensor such as a linear encoder and feeding back the measured value of the displacement sensor in any of the above cases. Can do.

  The control unit 10 receives display target information including attribute information indicating an arbitrary attribute of the display target, generates a control signal for driving the pin 24 according to the attribute information, and outputs the control signal to the pin driving unit 21. Is. Here, the control means 10 includes a height calculation means 11, a generated force calculation means (driving force calculation means) 12, a tip shape determination means 13, a space pattern determination means 14, and a time pattern determination means 15. Prepare. The generated force calculating means 12 corresponds to the driving force calculating means described in the claims.

  Further, the control means 10 determines which pin 24 is driven based on the position information included in the display target information. Here, the control means 10 converts the position (coordinates) of the display target in the real space into the coordinates of the display means 23 and determines to drive the pin 24 closest to the converted coordinates. The control means 10 drives the pin 24 based on at least one of the height, generated force, tip shape, space pattern, and time pattern of the pin 24 to be described later with respect to the pin 24 determined to be driven. Control signal is generated.

Here, the display target is, for example, a person, an object, or a figure. The display target may be a region such as a country, a prefecture, a municipality, or the like.
The attribute information can be arbitrarily determined. For example, if the display target is a person or an object, the attribute information includes temperatures such as temperature and body temperature, weight (weight), and height (height). If the display target is an object, the surface of the object is soft. Further, when the display target is divided into several categories, an identifier indicating a person or an object can be used as attribute information. For example, in the case of displaying sports such as soccer, the identifier includes a distinction between a team, a ball, or a line.
Note that the display target information may include information other than the attribute information. Here, the display target information includes position information indicating the position (coordinates) of the display target in order to determine which pin 24 is to be controlled.

  For example, in the case of an image composed of a pattern of pixel values (color and luminance), the control means 10 samples the image according to the arrangement of the pins 24 and generates a control signal. And the pin drive means 21 drives the pin 24 based on this control signal. As a result, the tactile information display device 1 controls the height of each pin 24 in accordance with the pixel value (color or luminance) at the sampling point, so that this image can be displayed tactilely. In this case, the coordinates of each pixel of the image are position information, and the pixel value is attribute information.

  The tactile information display device 1 can also display sports matches such as soccer. For example, a case will be described in which a player or a ball in a soccer court having a width of 105 m and a height of 68 m is displayed on the display means 23 including 105 pins horizontally and 68 pins vertically. In this case, the control means 10 divides the soccer court into 105 × 68 squares, associates each square with each pin 24, and generates a control signal. And the pin drive means 21 drives the pin 24 corresponding to the place of a player or a ball based on this control signal.

  The control means 10 can be composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory).

  The height calculation unit 11 calculates the height of the pin 24 from the attribute information based on a preset correspondence relationship between the attribute information and the height of the pin 24 indicating two or more different heights. The correspondence relationship between the attribute information and the height of the pin 24 includes, for example, a preset height calculation rule or height correspondence information for calculating the height of the pin 24 from the attribute information.

  Some of these height calculation rules compare a preset threshold value with attribute information, and calculate the height of the pin 24 based on whether or not the attribute information exceeds the threshold value. Further, in this height calculation rule, there is a rule for calculating the height of the pin 24 using a function having attribute information as an argument. The height correspondence information will be described later.

  The generated force calculation means 12 generates the generated force from the attribute information based on a preset correspondence relationship between the attribute information and a generated force (driving force) indicating a force when driving the pin 24 at two or more different heights. Is calculated. The correspondence relationship between the attribute information and the generated force includes, for example, a preset generated force calculation rule or generated force correspondence information for calculating the generated force from the attribute information. The generated force correspondence information will be described later.

Some of the generation force calculation rules compare a preset threshold value with attribute information, and calculate the generation force based on whether or not the attribute information exceeds the threshold value.
In addition, in the generated force calculation rule, there is a rule for calculating the generated force using a function having attribute information as an argument. As this function, for example, there is an equation (1) that shows the weight M and the generated force F of the object as a function.
Formula (1) F = aM + b (a and b are predetermined constants)

  Hereinafter, with reference to FIG. 3, control of the height and generated force of the pin will be described (see FIG. 1 as appropriate).

  Note that the height 0 means that the tip of the pin 24 is supported at substantially the same height as the flat surface 23a of the display means 23 (the pin is low). The height H is a state in which the tip of the pin 24 is supported at the highest position within the movable range in the vertical direction of the pin 24 (the pin is the highest). Furthermore, the height h is a state in which the tip of the pin 24 is supported approximately halfway between the height 0 and the height H (the pin is slightly high).

  As shown in FIG. 3A, the height calculation means 11 calculates the heights 0, h, and H of the pins 24 indicating three different heights. In this case, when the height calculating unit 11 calculates the height 0, the pin driving unit 21 drives and supports the pin 24 so that the tip of the pin 24 is substantially the same height as the flat surface 23a of the display unit 23. (State 1). When the height calculating unit 11 calculates the height h, the pin driving unit 21 drives the pin 24 so that the tip of the pin 24 is positioned approximately in the middle between the height 0 and the height H. Support (state 2). Further, when the height calculation means 11 calculates the height H, the pin 24 is driven and supported so that the tip of the pin 24 is at the highest position (state 3).

Further, as shown in FIG. 3B, the height calculation means 11 calculates the heights 0 and H of the pins 24 indicating two different heights, and the generated force calculation means 12 calculates two different generated forces. F _A and F _B may be calculated and combined. In this case, the drive means 21 drives the pin 24 with the generated force F _A until the tip of the pin 24 reaches the height H (state 2). The drive means 21, to the tip of the pin 24 is the height H, to drive the pin 24 in the generated force _{F B} (state 3). It should be noted that the generated force F _A is weaker than the generated force F _B.

When the object surface roughness does not exceed the threshold value, the object surface is smooth and the tip shape is determined. 1 is determined.
Some of the tip shape determination rules determine the tip shape using a function having attribute information as an argument. The tip shape correspondence information will be described later.

Accordingly, the tip shape determining means 13 determines the tip shape of the pin 24. As a correspondence relationship between the spatial pattern and the attribute information, for example, there is a preset spatial pattern determination rule for determining a spatial pattern from the attribute information or spatial pattern correspondence information.

  Some of these spatial pattern determination rules compare a preset threshold value with attribute information, and determine a spatial pattern based on whether or not this attribute information exceeds the threshold value. Some of these spatial pattern determination rules determine a spatial pattern with a function having attribute information as an argument.

  First, at the start of a soccer game, the control means 10 displays the display target information indicating the soccer game, specifically, the location of nothing, the soccer court line, the team A player, the team B player, and the ball position. Display target information including information and attribute information (identifier) is input. Moreover, the control means 10 determines the pin 24 corresponding to each from the soccer court line, the player of Team A, the player of Team B, and the position (coordinates) of the ball. Then, the time pattern determination means 15 searches the time pattern correspondence information of FIG. 9 with the identifier indicating the soccer court line, the player of Team A, the player of Team B, or the ball, and determines the time pattern for each pin 24. . Further, the time pattern determination unit 15 causes the height calculation unit 11 to change the height of the pin 24 according to the time pattern determined for each pin 24. Thereafter, the pin driving means 21 drives the pins 24 in a time pattern, and the soccer game at the start is displayed on the display means 23.

  In addition, during the soccer game, the control means 10 receives display target information including the moved team A player, the team B player, and ball position information and attribute information (identifier). On the other hand, since the line is unchanged, it does not have to be included in the display target information. Similarly to the above, the pin driving means 21 drives the pins 24 in a time pattern, so that a soccer game in the middle of the game is displayed on the display means 23.

Furthermore, an identifier such as when the ball is strongly kicked (shoot) or when the ball is kicked weakly (pass) may be included as attribute information. In this case, the tactile information display device 1
When the ball is kicked strongly, the generated force is strong. When the ball is kicked weakly, the generated force is weakened, and the strength of the ball can be expressed by the generated force. As described above, the tactile information display device 1 can dynamically display sports matches such as soccer.
