However, in the technique disclosed in the above-mentioned patent document, the user needs skill to recognize and interpret the presented information, and it is difficult to present the information without relying on vision.
As means for solving this problem, information presented by the information presentation device is associated with a predetermined position, and when the predetermined position (hereinafter referred to as “information position”) is touched by the user, a tactile information element such as vibration It is conceivable to generate the error.

  However, even in this method, when the user performs a touch operation on a position other than the information position, a clue to reach the information position is not shown. For this reason, useless operations of the user such as so-called “stray finger (performing an unnecessary contact operation until the target position is searched)” cannot be prevented, and there is a problem that information transmission efficiency and operation efficiency are lowered. .

  The present invention has been made to solve the above problems, and an object of the present invention is to make it possible to present information without depending on a user's vision while improving information transmission efficiency.

  The present invention has been made in view of these problems. That is, the information presentation apparatus of the present invention is an information presentation apparatus for presenting information using tactile perception, and detects a contact operation by a user. Contact detecting means, tactile information presenting means for transmitting information via the tactile sense, and tactile information control means for controlling the tactile information generated by the tactile information presenting means, contact by the user's contact operation The content of the tactile information is changed according to the distance between the position and the information position.

The information presentation method of the present invention is an information presentation method for presenting information using tactile perception, the step of detecting a contact operation by a user, and the step of transmitting information via a tactile sense. And a step of controlling the generated haptic information, wherein the content of the haptic information is changed according to the distance between the contact position and the information position by the user's contact operation.

  According to the present invention, since the user can surely recognize the information position, the user can know the information in relation to the position. In addition, when the user performs a touch operation on a position other than the information position, a clue to reach the information position is indicated, so that the user can quickly recognize the information position, and information transmission efficiency is improved.

Hereinafter, preferred embodiments of an information presentation apparatus and an information presentation method according to the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a main configuration of an information presentation apparatus for presenting information using tactile perception according to the present invention. In the figure, reference numeral 11 denotes a contact detection means. When a contact operation by the user is detected, the contact position is transmitted to the arithmetic processing unit 12. The arithmetic processing unit 12 calculates the distance between the contact position and the information position, and determines the content of the tactile information, that is, for example, the frequency or amplitude, the displacement amount, the displacement speed, or the like. Further, the tactile information presenting means 14 is controlled through the tactile information control means 13 to generate tactile information.

Here, the hardware configuration of the device of the present invention will be described. FIG. 6 is a block diagram showing an example of a schematic hardware configuration of the information presentation apparatus 100 according to the present invention.
The information presentation apparatus 100 includes a CPU 101 that is a central processing unit that controls the entire apparatus, a display unit 102 that displays various input conditions and analysis results of the present embodiment, a hard disk that stores analysis results of the present embodiment, and the like. A storage unit 103 is included. In addition, a ROM (Read Only Memory) 104 that stores the control program, various application programs, data, and the like of the present embodiment is provided. The CPU 101 includes a RAM (Random Access Memory) 105, which is a work area used when the CPU 101 performs processing while controlling each unit based on the control program, and an input unit 106 such as a keyboard and a mouse.

  2 shows an example of the appearance of the information presentation apparatus shown in FIG. 1 together with the user's finger K (FIG. 2 (A)), and tactile information (frequency etc.) generated in response to a user's contact operation. It is the graph (FIG.2 (B)) which represented the relationship with a user's operation position in contrast with FIG.2 (A).

  In the figure, when a position other than the information position 22 is touched by the user (contact position 21), the information presentation device according to the embodiment of the present invention displays tactile information according to the distance d between the contact position 21 and the information position 22. appear. When the user slides his / her finger to contact another position, the distance between the contact position 21 and the information position 22 changes, so that the generated tactile information also changes. Therefore, since the user can know whether the information position 22 is approaching or moving away based on this change, it can be used as a clue to reach the information position 22.

  In FIG. 2B, as an embodiment in which the frequency obtained by multiplying the distance d between the contact position 21 and the information position 22 by a constant is generated as tactile information, the vertical axis represents the frequency and the horizontal axis represents the position. This is shown in the graph.

  In the figure, when a contact operation is performed by the user, a frequency that is a constant multiple of the distance d between the contact position 21 and the information position 22 is determined. When the user slides his / her finger and touches another position, the distance between the contact position 21 and the information position 22 changes, so the frequency also changes. In this example, the greater the distance d, the greater (higher) the frequency. Based on this change, the user can know whether the information position 22 is approaching or moving away. That is, the content of the tactile information is changed according to the increase / decrease of the distance between the 21 contact position and the information position 22.

  Further, in the illustrated example, when the information position 22 is touched by the user, the frequency is zero, so that the user can know that the contact position 21 matches the information position 22. Even when the contact position 21 and the information position 22 do not exactly coincide with each other, the frequency may be set to zero as long as they are very close to each other.

  In the above case, it is possible to generate different types of tactile information when the contact position 21 and the information position 22 match or are in the vicinity. That is, when the contact position 21 and the information position 22 coincide with each other, for example, amplitude or the like can be used as different types of tactile information instead of the frequency corresponding to the distance d.

  FIG. 3 is a flowchart for explaining a flow of determination processing in which the information presentation apparatus according to the embodiment of the present invention detects contact by a user and generates tactile information corresponding to the distance between the contact position and the information position.

  In the figure, the information presentation apparatus according to the embodiment of the present invention calculates the distance d between the contact position and the information position when the user performs a contact operation (step S301) (step S302). Then, the frequency or amplitude, displacement amount or displacement speed of the tactile information is determined according to the distance d (step S303), and the tactile information presenting means 14 is driven and controlled by the tactile information control means 13 to generate tactile information ( Step S304).

FIG. 4 shows an example of how the information presentation apparatus according to the embodiment of the present invention is used, and shows an external view when mounted on a digital camera.
In the figure, an information presentation device 41 is incorporated in the digital camera 40 as a user interface for presenting predetermined operating characteristic values of the digital camera, such as a shutter speed value, to the user.

  Here, the user can know what operation characteristic value the information position of the information presentation device 41 shows by the gauge 42 provided in the vicinity of the information presentation device 41. When the user touches the finger with any position of the information presentation device 41, the user can reach the information position by the above-described method while sliding the finger, and knows the operation characteristic value such as the shutter speed. To get.

  It should be noted that the user can know in advance what operating characteristic value the information position indicates based on an operation manual or the like, or can know it as an experience value by repeatedly using the device. For this reason, it does not necessarily need to be indicated by a gauge or the like at the time of use. In other words, the gauge and the like are not essential components of the present invention.

  FIG. 5 shows a further example in which the information presentation device 51 according to the embodiment of the present invention is applied to, for example, a digital camera 50. That is, an example configured in a curved shape (FIG. 5A), an example configured in a plane (FIG. 5B), and an example configured in a circle (FIG. 5C) are shown. As in this example, the information presentation apparatus according to the present invention does not necessarily need to be configured in a straight line, and can take various forms other than those illustrated in FIG.

  When the information presentation device of the present invention is configured in a circle, the term “distance between the contact position and the information position” in the claims should be understood as “the opening angle between the contact position and the information position”. That is, it goes without saying that the term includes a semantic concept that is equivalent in view of the configuration and the working mechanism.

It is a block diagram which shows the principal part structure of the information presentation apparatus by this invention. It is a figure which shows the example of an external appearance of the information presentation apparatus shown in FIG. 1 with a user's finger, and a figure which shows the example of tactile information.
