Description

  The present invention relates to an information providing apparatus such as a robot, a preliminary information providing method, and an information providing program, which are equipped with a touch panel display at a place such as a shopping center and provide guidance and information according to user operations.

In public places such as shopping centers and museums, information providing devices such as robots that provide information on facilities and information on events to visitors and visitors are becoming installed. Such an information providing apparatus is made as simple as possible by an operation by a visitor to provide useful information to the visitor. For example, when a touch panel display is used for providing information, the GUI (Graphical User Interface) is generally devised in terms of the arrangement and color of operation buttons or the screen hierarchy so that anyone can understand at first glance. The desired information can be obtained by touching the operation buttons according to the contents displayed on the screen.
As described above, consideration is given to the method of creating the screen from the viewpoint of operation, but it is necessary to further devise in order to provide information according to the visitor who performs the operation. For example, it is possible to distinguish whether a visitor is an adult or a child and provide information accordingly. Proposals have been made to solve this.
For example, a plurality of types of operation guide information are stored in advance, and an “adult” button and a “kid” button are displayed as buttons of user attribute information on the initial screen of the touch panel display. When the user touches (selects) any of the above buttons on the screen, the attribute information of the adult or child user is acquired, and an operation guide corresponding to the acquired attribute information is selected and displayed on the screen. . That is, when the “adult” button or the “child” button is selected, a GUI screen suitable for the user is switched to provide a predetermined service (Patent Document 1).
In addition, a method for automatically identifying an adult and a child by detecting the height of a visitor has been proposed. In this method, the information providing robot includes means for detecting the height of the visitor, and the mode of adult, child, infant or the like is determined according to the detected height. Separately, information related to the introduction contents, utterances, gestures, etc. of the robot is registered in association with the mode, the mode information determined from the registered information is read, and the robot is executed based on the read information ( Patent Document 2).
JP 2006-28579 A Japanese Patent Application No. 2006-237896

  As described above, the GUI of the information providing apparatus is designed so that a visitor can obtain information required by a simple operation. However, these GUIs are not based on GUIs that automatically discriminate whether a visitor is an adult or a child and respond to it. Also, in response to the fact that an infant whose screen was not understood or a mischievous child hit the screen appropriately, he provided unnecessary guidance and information to the child. Furthermore, in the case of an elderly person with weak visual acuity, in the past, the user had to look closer to the display and give up if the reading was still impossible.

  The proposed method according to Patent Document 1 is a GUI in a format generally used in a library collection search system of a library. This method has a problem that the user has to select for adults and children, forcing the user to perform the operation. Also, the method proposed in Patent Document 2 is that the information providing robot automatically detects the height of the user and judges the adult and the child, so that the user is forced to perform the judgment operation. Absent. However, with this detection method, there is a high possibility that a person using a wheelchair will be judged as a child.

  The present invention determines whether the person is an adult, a child, or an adult with low vision from the touch information on the touch panel display and the information on the head position and distance of the visitor, and provides information suitable for the visitor.

  According to the fourth invention, an information providing method having the same effect as that of the first invention can be provided.

  According to the fifth invention, an information providing program having the same effect as that of the first invention can be provided.

  An embodiment of an information providing apparatus will be described with reference to FIGS.

  FIG. 1 shows an example of the overall configuration of an information providing apparatus 100 according to the present invention. The information providing apparatus 100 executes a control unit 110 that controls the whole, an input / output control unit 120 that controls input / output devices of a touch panel display 130, a CCD (Charge Coupled Device) camera 140, and a speaker 150, and an information providing program 170. The memory 160, the user's head position and distance information, the acquisition data storage unit 180 that stores the coordinate information acquired from the touch panel display 130, and the provision information storage unit 190 that stores the provision information.

  The touch panel display 130 displays provided information and, when the user touches (touches) the surface of the touch panel display 130, outputs a coordinate value following the touch. The CCD camera 130 is a so-called stereo camera in which two CCD cameras are arranged at regular intervals. For example, a facial feature is extracted from an image captured by the CCD camera 130, and the user's head is extracted based on the principle of triangulation. The part position (height) and the distance between the user and the information providing device are obtained.

  The information providing program 170 includes a touch information acquisition unit 171, a head position / distance detection unit 172, a touch determination unit 173, an adult / child determination unit 174, a wheelchair determination unit 175, a low vision determination unit 176, and a provided information display unit 177. Become. The outline of the program of each part will be described next.

  The touch information acquisition unit 171 acquires a coordinate value output from the touch panel display 130 for a predetermined time from when the user first touched while displaying the initial screen on the touch panel display 130, and stores the coordinate value as acquired data. Stored in the unit 180. It is assumed that a button for information to be provided is displayed on the initial screen, and when the user touches this button, the corresponding information is displayed on the touch panel display.

  The head position / distance detection unit 172 obtains the “distance” between the “head position” of the user and the information providing device from the image captured by the CCD camera 130 and stores it in the acquired data storage unit 180.

  The touch determination unit 173 extracts the coordinate value in the area of the button that provides information from the coordinate values stored in the acquired data storage unit 180, and obtains the ratio of the extracted number of coordinates to the total number of coordinates. If the ratio is equal to or higher than a predetermined ratio, the user's touch is determined as “effective touch”. Otherwise, it is determined as “invalid touch”.

  The adult / child discrimination unit 174 discriminates “adult” from the height of the head obtained by the head position / distance detection unit 172 if it is equal to or higher than a predetermined height. Determined as “children”.

  The wheelchair discriminating unit 175 determines that “adult in a wheelchair” if the “distance” obtained by the head position / distance detection unit 172 exceeds a predetermined distance when the adult / child discriminating unit 174 discriminates “child”. And the determination is changed from “child” determined earlier to “adult”.

  The weak-sighted person discriminating unit 176 detects the head position again by the head position / distance detection unit 172 and displays the head position when the providing information display unit 177 described below displays the providing information for adults. Ask. If the head position at this time is lower than a predetermined value from the previously obtained head position (head position stored in the acquired data storage unit 180), the image displayed on the touch panel display 130 In order to view the image, it is considered that the head is close and the head position is lowered, and the user is determined to be a low vision person. Then, the provision information displayed by the provision information display unit 177 is enlarged.

  The provided information display unit 177 retrieves corresponding provided information from the provided information storage unit 190 based on the result determined by the adult / child determining unit 174 when the touch determining unit 173 determines “effective touch”, and the touch panel. This is displayed on the display 130. That is, “adult provision information” is displayed if “adult” is determined, and “provided information for child” is displayed if “adult” is determined. If the touch determination unit 173 determines “invalid touch”, the invalid touch information is similarly extracted from the provided information storage unit 190 and displayed on the touch panel display 130 based on the result determined by the adult / child determination unit 174. To do.

  Next, an example of data stored in the acquired data storage unit 180 will be described. FIG. 2 shows an example of acquired data, which is composed of fields of “time”, “touch coordinates”, “button type”, and “head position / distance”. For example, in the data on the first row, the first touch time is 10: 34: 1.20, the X and Y coordinates on the screen are x1, y1, the head position is L1, and the distance is D1. It is shown that. As for the time, time information is acquired from a time measuring unit not shown in FIG. Also, the button type is “Button A” in the first line, but this is to obtain coordinate information and whether the coordinate information is within the area of the provided information button compared to the image data of the initial screen. I have investigated and recorded.

  A method of recording in the “button type” field will be described with reference to FIG. FIG. 3 shows an example of an initial screen. Here, there are two buttons, a provision information A button 132 and a provision information B button 133, and touching these buttons will display the corresponding information (if the provision information A button 132 is touched). The provision information A is displayed, and the provision information B is displayed by touching the provision information B button 132). For example, if the touched coordinates are on these button areas, “Button A” or “Button B” is recorded in the button information field, and “Invalid” is recorded in the other screen areas 131. Since the coordinate values x1 and y1 in the first row are in the area of the provided information A button, “Button A” is recorded. Since the coordinate values of x1, y2 in the third row are not located in the area of the provision information A button 132 or the provision information B button 133, “invalid” is recorded.

  Next, an example of obtaining the head position and distance in the head position / distance detection unit 172 will be described. FIG. 4 shows the positional relationship between the information providing apparatus 100 and the user 200 who uses the information providing apparatus 100. The information providing apparatus 100 is in the form of a robot here, and a CCD camera 140 is disposed at the position of the eyes of the robot. A touch panel display 130 is arranged at the chest position. If the user 200 looks at the initial screen displayed on the touch panel display 130, for example, shown in FIG. 3 and requests the provision information A, the user 200 touches the “provided information A button” on the screen.

  The information providing apparatus 100 uses the CCD camera 140 as a trigger to determine the head position L1 and the distance D1 of the user 200 using the touch. More specifically, a facial part is first identified based on facial features (eyes, nose, mouth) in images captured by the two CCD cameras 140, and the facial part is determined based on the triangulation principle from the two facial parts. Find the position (height and distance). A numerical value (for example, 10 cm) at the center height of the face is added to obtain a head position (head height) (the height of the face may be the head position). The head position obtained here is used by the adult / child discrimination unit 174 to discriminate between “adult” and “child”.

  Next, an example of “wheelchair” determination by the wheelchair determination unit 175 will be described. FIG. 5 shows a state where a user 300 in a wheelchair is going to use the information providing apparatus 100. For comparison, the child 400 is also in a state of trying to use the information providing apparatus 100. In this case, the adult / child discrimination unit 174 determines that the head position L2 and the child head position L3 of the user 300 in the wheelchair are both “children”. Therefore, when it is determined as “child”, the distance between the user 300 and the information providing apparatus 100 is checked, and if it is equal to or longer than the predetermined distance, it is determined as “adult” (the determination of “child” is withdrawn, and “ Will be identified as "adult"). Here, it is determined that the distance D2 of the user 300 is an “adult” on the wheelchair at a distance greater than or equal to a predetermined value, and the distance D3 of the child 200 is less than a predetermined value, and thus is determined as “child”. It is used that the child's standing position is generally closer (shorter distance) than the user on the wheelchair.

  Next, an example of “low-sighted person” determination by the low-sighted person determination unit 176 will be described. FIG. 6 shows a state where a user with weak eyesight is viewing the display with the face approaching the touch panel display 130 when the provided information is displayed on the touch panel display 130. Compare the user's head position during display with the head position when first touched from such a state, and if the height changes lower than a certain value, it is determined that the person is weakly sighted It is. For example, the head position (height) of the user 200 in FIG. 4 is L1, but in FIG. 6, the head position is changed to L1 ′. In such a case, it is determined that the user is “low-sighted”.

  Finally, the processing flow of the information providing apparatus 100 will be described with reference to FIG. The processing flow of FIG. 7 shows processing when the user touches (touches) the touch panel display 130 of the information providing apparatus 100 in the state where the initial screen displaying the provision information button is displayed as described above. . First, the touch panel display 130 senses the first screen touch and acquires coordinate values following the touch on the screen for a predetermined time. For example, when coordinate values are acquired for one second at a sampling rate of 100 points / second, 100 coordinate values are acquired. Then, the acquired coordinate value is stored in the acquired data storage unit 180. Subsequently, the user's head position and the distance from the information providing apparatus 100 are obtained using the CCD camera 140, and these values are also stored in the acquired data storage unit 180 (steps S100 and S110 in FIG. 7; hereinafter simply referred to as Sxx). ).

  For the coordinate values stored in the acquired data storage unit 180, the ratio of the number of coordinate values in the area of the provided information button displayed on the initial screen to the total number of coordinates is obtained. For example, when there are two provision information buttons (provided information A button and provision information B button) as shown in FIG. 3, the ratio of the number of coordinate values in the area of the provision information A button to the total number The ratio of the number of coordinate values in the area of the provided information B button to the total number is obtained. If the calculated ratio is equal to or greater than a predetermined ratio (the predetermined ratio is “B” in FIG. 7), it is regarded as “valid touch”, and when it is less than the value, it is regarded as “invalid touch” ( S120, S130).

  In the case of “effective touch”, the head position obtained in S110 is determined to be “adult” when the head position is equal to or higher than a predetermined height (the predetermined height is “L” in FIG. 7; for example, L = 140 cm). Otherwise, it is determined as “child”. When “adult” is determined, “provided information for adults” is displayed. This “provided information for adults” is stored in advance in the provided information storage unit 190 together with “provided information for children”. Based on the determination of “adult”, the provision information for the corresponding adult is read from the provision information storage unit 190 and displayed on the touch panel display 130. “For adults or children” is information provided for adults and children, such as expressions, characters, or designs (S140, S150).

  When “provided information for adults” is displayed, the head position of the user is obtained again after a certain period of time has elapsed after the display (for example, after 3 seconds). When the obtained head position is lower than a certain value by the head position stored in the acquired data storage unit 180 (this head position is the first touched position) (the value in FIG. 7 is “ΔL”). ), The user brings his / her face close to the screen, so that the user is regarded as “low-sighted”, and the provided information being displayed is enlarged. Otherwise, the enlarged display is not performed (S160-S180).

  When the head position is less than the predetermined height in S140, it is determined as “child”, but the distance obtained in S110 is a predetermined distance (the predetermined distance in FIG. 7 is “D”). For example, if it is 40 cm or more, the determination is changed to “adult”. That is, even if the head position is low, it is regarded as an “adult” on a wheelchair if the distance is long. In this case, “barrier-free information” is displayed together with “provided information for adults”. For example, if the provided information is guide information in the store, it is information that hand washing on odd floors is barrier free. If the distance is less than the predetermined distance, the user is determined to be “children” and “provided information for children” is displayed (S190, S210).

  Next, a flow when it is determined as “invalid touch” in S130 will be described. After “invalid touch” is determined, “adult” and “child” are determined at the head position obtained in S110 in the same manner as “effective touch”. If “adult” is determined, “invalid touch for adult” is displayed. Even if it is determined as “Children”, as with “Effective Touch”, if the “Distance” of the position where the user stands is more than a certain value, the determination is changed to “Adult”, otherwise it is determined as “Children” Then, “invalid touch for child” is displayed. The display of “invalid touch for adults or children” is created by creating expressions, characters or designs for adults and children in the same manner as described above. Information indicating this invalid touch is also stored in advance in the provided information storage unit 190, read out from the provided information storage unit 190 based on the discrimination result of “adult” and “child”, and displayed on the touch panel display 130 (S220). -S250).

  Heretofore, an example of the processing flow of the provided information device 100 has been described. Here, the head position and the distance are obtained after obtaining the coordinate values, but they may be obtained after obtaining the ratio of the provision information button area of the coordinate values.

  The provided information may be transmitted to the user by voice through the speaker 150.
