  As shown in FIG. 1, a multimedia sticky note device (hereinafter simply referred to as “sticky note device”) 10 of this embodiment is used by being held in the hand of a user 1. In this embodiment, the sticky note device 10 is a portable information terminal that can be held by hand, and, as an example, an Apple mobile phone iphone3G (product name) is used. However, not only a mobile terminal having a specific product name but also a mobile phone having an equivalent function and an arbitrary mobile information terminal such as a PDA can be used.

  For example, when the user 1 operates the tag device 10 in the real space, the voice data, video or image data, text data, or stroke is moved to the position or direction of the virtual space corresponding to the position or direction in the real space. Place multimedia contents such as data as sticky notes (write and paste necessary items and peel them off when they are no longer needed, for example, “Post-It” (product name)), or delete sticky notes once placed Or the content that constitutes the tag that is placed.

  FIG. 2 illustrates a sticky note device 10 in the case of an embodiment which is a mobile phone ifphone3G (product name). The sticky note device 10 includes a substantially rectangular flat housing 12, and a display 14 such as an LCD (Liquid Crystal Display) is provided on the front surface of the housing 12, and a touch panel 16 is disposed on the display 14. The The touch panel 16 may be either a resistive film type or a capacitance type, or may be another type of touch panel if present.

  A push button switch 18 called a “home button” is provided on the front surface of the housing on the right side of the display 14. The switch 18 is used for various menus, a camera shutter, and various other hardware. Switch. A microphone 20 indicated by a dotted line in FIG. 2 is provided on the right side above the switch 18. The microphone 20 constitutes voice input means or a part thereof.

  A camera 22 indicated by a dotted line in FIG. 2 is provided on the rear surface of the left housing of the display unit 14. The camera 22 constitutes a video or image input means or a part thereof. A speaker 24, which is an example of an audio output unit, is disposed on the front surface of the housing 12 below the camera 22.

  A virtual space is displayed on the display 14, and in the virtual space, a sticky note object 26 and sticky note icon objects 26a1, 26a2 indicating the presence of sticky note data (audio data, video or image data, text data, stroke data, etc.). , 26a3, ... are displayed. By these tag object 26 and tag icon objects 26a1, 26a2, 26a3,..., The user 1 can visually know that the tag data is arranged at the position and / or direction. However, the difference between the sticky note object 26 and the sticky note icon objects 26a1, 26a2, 26a3,... Is that the sticky object 26 has a position or direction at that time of the sticky note device 10 and a sticking gesture for sticking the sticky note data of the sticky note object 26. Indicates that the position or direction in the real space has been matched or almost matched, whereas the tag icon objects 26a1, 26a2, 26a3,... Are in positions or directions different from the position or direction of the tag object 26. Indicates that sticky note data is pasted.

  Here, the place information indicating the current position or direction of the sticky note device 10 matches the place information indicating the position or direction in the real space where the sticking gesture for pasting the sticky note data of the sticky note object 26 is made. In order to detect that the two sticky note data are substantially coincident, it may be determined whether the positions or directions of the two sticky note data are completely coincident with each other, or whether the positions or directions of the two sticky note data are substantially coincident with each other. May be. In the former case, in the embodiment, it is only necessary to determine whether the azimuth data detected by the electronic compass matches. In the latter case, it is possible to determine whether the azimuth data overlaps within a predetermined range (for example, 5 °). it can.

  More specifically, when using the sticky note device 10 of the embodiment, the user 1 inputs multimedia content data (sticky note data) to the sticky note device 10 and holds the sticky note device 10 in his hand, as shown in FIG. By executing a pasting gesture (described later) at an appropriate position and / or direction of the surrounding AR surrounding the user 1 in the real space, the sticky note data is placed (pasted) at that position and / or direction. When the sticky note pasted in this way is reproduced, the sticky note device 10 is moved so that the sticky note icon object 26a indicating the presence of the sticky note data is in the position and / or direction indicated by the sticky note object 26 in FIG. Move around AR. In the embodiment, the sticky note icon objects 26a1, 26a2, 26a3,... Are displayed in a lighter color than the sticky note, and when the sticky note device 10 is brought to a position and / or direction recognized as a sticky note, the sticky note object having a darker color. The display color is changed so that it can be recognized as H.26.

  When the sticky note device 10 is brought to a predetermined position or direction of the surrounding AR, that is, in a state where the sticky note object 26 can be recognized, the sticky note data (multimedia content) forming the sticky note object 26 is automatically used in the embodiment. To be played. For example, if the tag data is audio data, audio is output from the speaker 24 or from a headphone (not shown). If the tag data is video or image data, the video or image is displayed on the display 14 (FIG. 2). Similarly, when the tag data is text data, the text indicated by the text data is displayed on the display 14. When the tag data is stroke data, a line drawing or character indicated by the stroke data is displayed on the display 14. Note that the stroke data is sequential coordinate data on the touch panel representing line drawings and characters directly drawn on the touch panel 16. With this stroke data, a handwritten memo can be stored and reproduced as a sticky note.

  Note that the video or image may be a moving image or a set of one or a plurality of still images. For example, a still image of a handwritten memo can be generated as sticky note data by photographing a memo handwritten on a blackboard, white board, or paper with the camera 22 of the sticky note device 10. That is, it is possible to leave a handwritten memo as a sticky note and reproduce it even with a video or an image.

  Referring to FIG. 4, the sticky note device 10 includes a display 14, a touch panel 16, a switch 18, a microphone 20, a camera 22, and a speaker 24 described above, as shown in FIG. 4, a three-axis geomagnetic sensor 28, A triaxial acceleration sensor 30, a CPU 32, a ROM 34, a RAM 36, a flash memory 38, and a clock circuit 40 are included.

  By displaying a keyboard image on the display 14 and detecting a user's touch at the key position shown in the keyboard image on the touch panel 16, key input can be performed. This is a so-called soft keyboard. The CPU (computer) 32 of the tag device 10 of the embodiment uses such a soft keyboard to input text data, select or specify a tag mode, determine the type of tag data, Necessary operations can be instructed to the computer (CPU) 32.

  Further, the operation of the switch 18 can be detected by the CPU 32, and when the CPU 32 detects the operation of the switch 18, the function set in advance according to the mode and timing at that time is achieved. For example, when the switch 18 is operated when the camera mode is set, this is regarded as a so-called shutter operation, and the CPU 32 captures the image from the camera 22 into the data area of the RAM 36 at that timing. When inputting audio or moving images, the CPU 32 may capture audio data and video data during the first operation of the switch 18 as a start instruction and the next operation as an end instruction.

  However, in the case of voice input, instead of instructing the start and end by operating the switch 18, it is also possible to determine whether or not voice input has been performed and automatically capture it. For example, the CPU 32 attempts to cut out a section (voice section) that is a voice signal (sound) from the voice signal input from the microphone 20 and determines that there is a voice input when the voice section can be cut out. In the extraction of the voice section, the position where the time when the level of the voice signal exceeds the threshold, for example, exceeds 0.3 seconds is regarded as the start of speech (voice section start), and the time when the level of the voice signal falls below the threshold after that, for example. The voice section is determined by regarding the position that starts to fall below the threshold when exceeding 1.0 second as the speech stop (speech section end).

  The triaxial geomagnetic sensor 28 detects the strength of geomagnetism in the orthogonal triaxial direction. In this embodiment, the triaxial geomagnetic sensor 28 is used together with the CPU 32 to configure an electronic compass or a digital compass. As is well known, the electronic compass combines two geomagnetic sensors at right angles to detect the geomagnetism in the front-rear direction and the left-right direction, and calculates which is the north direction from the strength. However, since the three-axis type as in the embodiment has a third geomagnetic sensor for detecting the geomagnetism in the vertical direction in addition to the two geomagnetic sensors in the front-rear direction and the left-right direction, for example, the tag device 10 is tilted. Even if you hold it, you can see how many times it is tilted by one geomagnetic sensor, and you can detect the correct orientation by subtracting the tilt and calculating the horizontal geomagnetism. Therefore, if it is determined that the sticky note device 10 is always used in a vertical position as shown in FIG. 2, it is not necessary to detect the inclination, so a biaxial geomagnetic sensor is sufficient.

  As will be described later, the triaxial or biaxial geomagnetic sensor 28 is used by the user to input a sticking gesture and a peeling gesture. In the sticking gesture and the peeling gesture, it is necessary to input an instruction of position or direction and an instruction of sticking and peeling operation, and this geomagnetic sensor 28 functions as a position or direction indicating means.

  In this embodiment, the triaxial acceleration sensor 30 is used for the user to input a sticking gesture and / or a peeling gesture, as will be described later. However, if it is determined that the above gesture is performed only in a predetermined direction, the acceleration sensor may be a biaxial one. As described above, in the sticking gesture and the peeling gesture, it is necessary to input a position or direction instruction and a sticking and peeling operation instruction, and the acceleration sensor 30 functions as a sticking and peeling operation instruction means.

  As described above, the sticky note device 10 includes the speaker 24, but a headphone (not shown) may be provided in place of the speaker 24 or in combination with the speaker 24. If stereo headphones are used, a voice memo (voice tag) can be reproduced so that the sound source can be localized.

  The RAM 36 included in the sticky note device 10 is provided with a program area 42 and a data area 44 as shown in FIG. In the program area 42, various programs preset in the ROM 34 are developed when used. For example, the OS area 421 stores an OS (Operating System). In the tag data generation program area 422, a program for generating and storing the tag data described above, for example, voice data, video or image data, text data, stroke data, and the like is set. When acquiring voice tag data, the CPU 32 captures voice input from the microphone 20 in accordance with the voice tag data generation program set in this area 422. When acquiring video or image tag data, the CPU 32 captures video or image input from the camera 22 in accordance with the video or image tag generation program set in this area 422. When acquiring the text sticky note data, the CPU 32 sets the above-mentioned soft keyboard according to the text sticky note generation program set in this area 422 and specifies the operation key according to the touch signal from the touch panel 16. Get keystrokes. When acquiring the stroke data, the CPU 32 inputs sequential coordinate position data indicated by the touch panel 16 (or another pointing device) according to the stroke data tag generation program set in the area 422.

  In the sticky note operation program area 423, a sticky note operation program for pasting or peeling a sticky note and further reproducing the sticky note data is set. When the sticky note data is played back by the sticky note operation program, the sound is output from the speaker 24 or headphones (not shown), the video or image is output to the display 14, and the line drawing and characters indicated by the text and stroke data are also displayed. Is output to the device 14.

  In the attached program area 424, an attached program for causing the CPU 32 to function the electronic compass, detecting a sticking gesture, a peeling gesture, and a front calibration gesture is set.

  In the data storage area 44 of the RAM 36, a display object image data storage area 441, a sensor data storage area 442, a tag data buffer 443, and the like are formed.

  In the display object image data storage area 441, tag image object 26 and tag icon object 26a as shown in FIG. 2, a keyboard image for a soft keyboard, and object image data for displaying other images are set in advance.

  In the sensor data storage area 442, geomagnetic data indicating the magnitude of geomagnetism detected by the triaxial (or biaxial) geomagnetic sensor 28 or the triaxial (or biaxial) acceleration sensor 30 and acceleration data indicating the magnitude of acceleration are stored. Remembered. The CPU 32 determines whether or not a gesture such as a sticking gesture or a peeling gesture has been performed using the geomagnetic data, using the geomagnetic data, or using the acceleration data in accordance with the attached program.

  The tag data buffer 443 is an area for temporarily storing audio data, video or image data, text data, stroke data, and the like input as tag data, and functions as a first storage unit. In response to the pasting gesture, the sticky note data is transferred from the buffer 443 to the flash memory 38 functioning as the second storage means and stored. In addition, the sticky note data registered in the flash memory 38 is transferred to the buffer 443 and stored in accordance with the peeling gesture.

  However, the flash memory 38 is an example of a non-volatile memory, and as the second storage unit, any other type of non-volatile memory can be used instead of the flash memory 38 or together with the flash memory 38.

  Referring to FIG. 6, CPU (computer) 32 of sticky note device 10 detects the operation of switch 18 as described above in step S1 according to sticky note data generation program 421 in program area 42 of FIG. Alternatively, it is determined whether or not there is an audio signal input from the microphone 20 by performing audio segmentation. When there is an audio signal input, the CPU 32 determines “YES” in step S1, converts the input audio signal into audio data, and stores it in the tag data buffer 443 shown in FIG. 5 in the subsequent step S3. In the case of stroke data, in the stroke data input mode, sequential coordinate position data indicated by the pointing device, in the embodiment, the touch panel 16 is written in the buffer 443.

  When determining “NO” in step S1, the CPU 32 determines whether a video signal or an image signal is input from the camera 22 by detecting an operation of the switch 18 in step S5. When the video signal or image signal is input, the CPU 32 converts the video signal or image signal into video or image data, and stores the video or image data in the tag data buffer 443 in step S7.

  If “NO” is determined in the step S5, the CPU 32 determines whether or not text data is input in a step S9. If there is an input of text data, the CPU 32 determines “YES” in step S 9, and stores the text data in the tag data buffer 443 in step S 11. When inputting the text data, the CPU 32 reads out the keyboard image data from the object image data storage area 441 in accordance with the user's operation when inputting the text, displays the keyboard image on the display unit 14, and displays the keyboard image. When a touch input from is detected, it is determined which key on the keyboard is operated (touched), and the text data is written in the buffer 443. Therefore, in order to determine whether or not the text is input in step S9, it is only necessary to determine whether or not there is such an instruction from the user.

  Further, two or more data of any combination such as audio and video or image, video or image and text, audio and text, and the like can be stored in the buffer 443 as one tag data. For example, a photograph with narration can be processed as one sticky note including audio data and video or image data. That is, the tag data may be not only single media data but also mixed media data.

  In this way, sticky note data is generated according to the sticky note data generation program, and stored in the sticky note data buffer 443 (FIG. 5).

  When the CPU 32 determines in step S21 in FIG. 7 that the pasting gesture has been performed, the sticky note data stored in the sticky note data buffer 443 is pasted in the virtual space. Specifically, it is stored in the flash memory 38.

  In this embodiment, both the sticking gesture and the peeling gesture can be executed by the movement of the tag device 10 itself. Specifically, the sticking gesture is shown in FIG. 8, and the peeling gesture is shown in FIG.

  In the sticking gesture shown in FIG. 8, the user holds the right end of the sticky note device 10 with the right hand so that the display device 14 is on the near side (self side), and in this state, the left side of the sticky note device 10 is as indicated by an arrow A. Shake the sticky note device 10 away from you. On the other hand, in the peeling gesture shown in FIG. 9, the user holds the right end of the sticky note device 10 with the right hand in the same manner as in FIG. 8, and the left side of the sticky note device 10 approaches the user as indicated by arrow B in that state. Shake device 10. This sticking gesture and peeling gesture can be detected by monitoring an output signal from the triaxial acceleration sensor 30 (FIG. 4) shown in FIG.

  FIG. 10A shows each axis output signal of the three-axis acceleration sensor 30, where the alternate long and short dash line indicates the X-axis acceleration, the dotted line indicates the Y-axis acceleration, and the solid line indicates the Z-axis acceleration. Each axis output signal of such an acceleration sensor is taken into the sensor data area 442 (FIG. 5) as A / D converted sensor data. The CPU 32 then performs high-pass filter processing on the sensor data in accordance with the attached program 424 to determine in what order the maximum value and the minimum value can be detected based only on the Z-axis acceleration data perpendicular to the screen. To do. When the snap operation as shown in FIG. 8 or FIG. 9 is performed, the acceleration of each of the X axis and the Y axis is smaller than that of the Z axis, so that the attached program only has the Z-axis acceleration data after the high-pass filter processing. It is determined which snap operation has been performed.

  As shown at point P1 in FIG. 10B, the fact that the maximum value of the Z-axis acceleration is input before the minimum value means that a force is applied to the front side of the display 14 of the sticky note device 10, that is, to its own side. Means that. Therefore, when the user causes the sticky note device 10 to perform a snapping motion as shown in FIG. 8, the CPU 32 determines that the pasting gesture has been performed. On the other hand, when it is detected that the minimum value of the Z-axis acceleration is input prior to the maximum value as at the point P2 in FIG. 10B, in this case, to the back side of the tag device 10 It means that the power of. Therefore, when the user causes the sticky note device 10 to perform a snap motion as shown in FIG. 9, the CPU 32 determines that a peeling gesture has been performed.

  However, the attached program is set so that the CPU 32 does not detect a gesture for a certain period of time (for example, about 2 seconds) after once detecting the sticking gesture or the peeling gesture. The reason for this is to prevent detection of an unexpected continuous input, and to prevent detection of a sticking gesture or a peeling gesture as if it were just a pattern to use a fan.

  Further, the sticking gesture and the peeling gesture can be input not only by such a snapping operation of the sticky note device 10 but also by causing the sticky note device 10 to generate another motion, and the movement (movement) of the attachment device 10 itself. Instead, for example, it is possible to input by the movement of the user's head, and it is also possible to input a sticking gesture or a peeling gesture by voice. The gestures such as the sticking gesture and the peeling gesture in the present invention are not limited to the specific examples described in the embodiments, and any gesture can be used as the sticking gesture and the peeling gesture.

  When the sticking gesture is detected as described above, the CPU 32 determines “YES” in step S21 of FIG. 7 in accordance with the sticky note operation program 423, and in the next step S23, the CPU 32 detects the sticky note data buffer 443 (FIG. 5). ) Is pasted into the virtual space. Specifically, the CPU 32 transfers the sticky note data from the buffer 443 to the flash memory 38 and stores it as shown in FIG.

  In FIG. 11, in one storage location of the flash memory 38, type data 46 indicating the type of sticky note data (sound, video or image, text, etc.), sticky note data 48, and orientation data 50 are stored together.

  The type data is a numerical value (code) indicating whether the tag data is audio data, video (image) data, or text data. For example, as shown in Table 1 below. However, stroke data is omitted.

  The shape and pattern (texture) of the tag object 26 and the tag icon object 26 shown in FIG. In that case, it is necessary to prepare an object image having a shape or pattern (texture) unique to each media type as display object image data. When the CPU 32 displays the tag object 26 or the tag icon object 26a as shown in FIG. 2, the CPU 32 selectively displays the tag object 26 or the tag icon object 26a having a shape or pattern (texture) according to the type of tag data. .

  The tag data 48 is data generated according to the tag data generation program shown in FIG. The azimuth data 50 is data indicating the “azimuth” in which the pasting gesture has been executed.

  As described above, the sticky note device 10 of this embodiment can execute the function of the electronic compass according to the attached program. The azimuth data 50 stored together with the sticky note data 48 is the azimuth detected by the electronic compass, and the azimuth of the sticky note device 10 when a sticking gesture is performed in real space when “north” is set to 0 °. It is the data shown. If it is assumed that the pasting gesture is performed at the position “10” in FIG. 3 and the direction at that time is “northeast”, 45 ° is written as the direction data 50.

  The real space orientation data 50 is stored in association with the sticky note data 48 in order to display the sticky note object 26 and the sticky note icon object 26a as shown in FIG. 2 at the position or direction in the virtual space corresponding to the real space orientation. Because it is necessary to do. However, in FIG. 2, for convenience, the range of 180 ° in front of the user 1 is set as the pastable range, but this range can naturally be expanded to 360 ° (strictly 359 °).

  Note that when a pasting gesture is detected in step S21, a pasting operation (transfer storage to the flash memory 38) is performed in step S23. If the position or direction (azimuth) of the sticky tag data pasted earlier is the same as the orientation detected by the compass), the display positions of the tag object 26 or the tag icon object object 26a shown in FIG. It may be necessary to deal with (processing).

  For example, before step S23, the CPU 32 determines whether or not the tag data already pasted and the tag data to be pasted at this time overlap in their positions or directions. In determining whether “overlapping”, it may be determined whether the positions or directions of the two tag data completely match, or whether the positions or directions of the two tag data are approximately the same. Good. In the former case, in the embodiment, it is only necessary to determine whether the azimuth data detected by the electronic compass matches. In the latter case, it is possible to determine whether the azimuth data overlaps within a predetermined range (for example, 5 °). it can.

  If the position or direction overlaps, the display of a message (for example, “Cannot be pasted because it is the same as the direction of the already pasted sticky note”) that rejects the sticking of the current sticky note data and informs the user to that effect. On the other hand, a method of deleting the rejected sticky note data from the sticky note data buffer 443 (FIG. 5) can be considered. However, other processing methods may be employed.

  For example, it is possible to display the message “Cannot be pasted because it is the same as the orientation of a sticky note that has already been pasted. Please change the pasting orientation.” And prompt the user to perform the pasting gesture again in a different orientation. is there. However, in this case, when the message is displayed, the sticky note data is not automatically deleted from the buffer, but when a pasting gesture is not detected within a predetermined time despite prompting another pasting gesture. Just delete the sticky note data from the buffer.

  When the pasting position or direction of the tag data is not overlapped with the position or direction of the pasted tag data from the beginning or when the user performs the pasting gesture again, the pasting position or direction of the two tag data is When there is no overlap, step S23 may be executed.

  When the sticky note data pasted in the virtual space in this way is reproduced, the operation is performed according to the flowchart shown in FIG. 12 based on the sticky note operation program 422 (FIG. 5). When the user operates an appropriate operation unit (not shown) to set the sticky note data reproduction mode, the CPU 32 refers to the stored contents of the flash memory 38 in the first step S31, as shown in FIG. The object 26 and the sticky note icon object 26a are displayed on the corresponding place in the virtual space by the display unit 14. As described above, since the flash memory 38 indicates the sticking location of the sticky note data in the real space as the azimuth data, the CPU 32 displays the sticky note object 26 and the sticky note icon object 26a in the real space. It is necessary to convert the azimuth indicated by the azimuth data into a position on the display 14, that is, an azimuth in the virtual space.

  For example, if the display 14 is set so that a virtual space of 180 ° as shown in FIG. 2 can be displayed by using the entire width, the display 14 has a real space at the center in the width direction. “North” and 90 ° from left to right, that is, “east” to “west” in the real space passing through the north can be displayed as a virtual space. Therefore, for example, if “45 °” is stored as the azimuth data 50 in FIG. 11, the tag data must be arranged at the location “northeast”. That is, in the state where the back surface of the sticky note device 10 is directed to “north” in the real space, the position of “northeast” when the left end of the display 14 is “west” and the right end is “east”, for example, the display 14 If the width is 8 cm, a place 4 cm from the right end is a place where the tag object should be displayed.

  However, when the full width of the display 14 is set to 360 °, the tag object must be displayed at a position 6 cm from the right end.

  By holding such a correlation between the real space azimuth and the virtual space azimuth (display position) as a table, for example, by converting the azimuth data read from the flash memory 38 into the width direction position of the display 14, The tag object 26 and the tag icon object 26a can be displayed at the correct display position.

  Thereafter, in step S33, the CPU 32 determines whether or not the orientations coincide. As described above, when the user tries to reproduce the tag data, the user changes the orientation of the tag device 10 in the real space so that the tag icon object is positioned at the tag object 26 in FIG. In step S33, it is determined whether or not the tag icon object can be recognized as the tag object 26. The user moves the sticky note device 10 in the real space until “YES” is determined in step S33. Along with this moving operation, the position or direction (direction in the embodiment) in the real space is input as the location information. In the embodiment, the sticky note device 10 has a built-in triaxial geomagnetic sensor 28, and the CPU 32 realizes an electronic compass function. Therefore, the moving operation of the sticky note device 10 becomes an input operation of direction, that is, location information.

  Furthermore, in the embodiment, in the above-described step S33, the orientation input by the user's input operation is the orientation associated with the sticky note data registered in the flash memory 38 as the second storage means as shown in FIG. Judgment is made whether they match. At this time, the sticky note icon object object changes to a sticky note object to indicate that the orientation input by the user matches the orientation in which the sticky note data is registered.

  However, it is not necessary that the input azimuth and the stored azimuth completely coincide with each other, and it is only necessary to have “coincidence” with a certain degree of tolerance. That is, in step S33, the inputted azimuth (ie, , Location information indicating position or direction) and the stored azimuth (that is, location information indicating position or direction) have only a predetermined relationship. If there is a predetermined relationship, "YES" is determined in step S33. Is judged.

  If "YES" is determined in the step S33, the CPU 32 reads the sticky note data recognized as the sticky note object 26 from the second storage means, that is, the flash memory 38 in the next step S35, and the first storage means. That is, the data is read into the tag data buffer 443 of the RAM 36. Then, the CPU 32 reproduces the tag data read to the buffer 443. That is, if the tag data is audio data, the audio is output from the speaker 24 or headphones (not shown). If the tag data is video or image data, the video or image is displayed on the display 14. When the tag data is text data, the text is displayed on the display 14. In the case of stroke data, the line drawing, characters, etc. indicated by the stroke data are displayed on the display 14.

  In this way, the user uses the tag device 10 in the surrounding AR shown in FIG. 3 in the real space with the tag and / or tag icon object (FIG. 2) in the virtual space displayed on the display 14 as a landmark. By moving (displace) the desired tag data can be selected and reproduced.

  When deleting the sticky note data once pasted, the CPU 32 executes the operation of FIG. 13 based on the sticky note operation program 422. First, in step S41, it is determined by monitoring the output signal (FIG. 10) from the acceleration sensor 30 whether or not the user has performed the peeling gesture by the method described above. If “YES” is determined in the step S41, the CPU 32 determines whether or not there is sticky note data pasted in the virtual space, for example, by referring to the data in the flash memory 38 in a step S43. That is, it is determined whether or not the sticky note data that can be recognized as the sticky note object 26 shown in FIG. 2 exists in the position or direction in the virtual space corresponding to the orientation in the real space of the sticky note device 10 at that time. If “NO”, the process ends. However, in practice, in the case of “NO”, the user moves the sticky note device 10 to a position or direction in the real space that can be recognized by the CPU as the sticky note object 26, so that the sticky note data is stored in the flash memory 38. Eventually, “YES” is determined in step S43.

  If “YES” is determined in the step S43, the CPU 32 reads out the corresponding sticky note data (matched in position or direction) in the flash memory 38 in the next step S45, and temporarily moves it to the buffer 443 (FIG. 5) ( Forward.

  In this state, a confirmation icon (not shown) is displayed on the display 14 or a sound is output from the speaker 24 to ask the user to confirm whether or not the tag data can really be deleted. When the user gives an operation input for permitting deletion or a voice input, the CPU 32 determines “YES” in step S47. If “YES” is determined in the step S47, that is, if the final confirmation of the user's deletion OK is obtained, the CPU 32 deletes the corresponding tag data transferred to the buffer 443 in a step S49.

  In this manner, the sticky note data once pasted can be peeled off in response to the peeling gesture. That is, the sticky note device 10 is displaced in the real space so that the position or direction in the virtual space changes, and the sticky note device 10 is in such a position or direction where the sticky note data to be deleted becomes the corresponding position or direction. The sticky note data can be easily deleted simply by performing a peeling gesture in the brought state.

  In the above-described embodiment, the sticky note device 10 has been described as including the triaxial (biaxial) geomagnetic sensor 28 and the triaxial (biaxial) acceleration sensor 30. However, a headset 46 as shown in FIG. 14 may be used, and the triaxial (biaxial) geomagnetic sensor 28 and triaxial (biaxial) acceleration sensor 30 may be incorporated therein. The headset 46 includes a microphone 48 and a stereo headphone 50, which can be used as an alternative to the microphone 20 and the speaker 24 of FIG. If the stereo headphones 50 are used as sound output means, the sound tag data can be reproduced so that the sound source can be localized.

  In the case where the three-axis (two-axis) geomagnetic sensor 28 is built in the headset 46, in the above-described embodiment, the sticking device 10 itself is moved to set a desired sticking position or direction. It can be set according to the orientation of the head of the user 1 wearing the headset 46. For example, the user 1 can specify the position or direction in the virtual space to be pasted in the real space only by directing the face (head) to the direction in which the target tag data is to be pasted. The direction in which the head is facing can be specified by the electronic compass function of the CPU 32 using the output data of the geomagnetic sensor 28.

  Further, in the case where the three-axis (two-axis) acceleration sensor 30 is built in the headset 46, in the above-described embodiment, a sticking gesture or a peeling gesture is performed by causing the sticky note device 10 itself to perform a snap motion. The input can be performed by the movement of the head of the user 1 wearing the headset 46. For example, when the user 1 pulls the chin while wearing the headset 46, a unique change in the acceleration data from the acceleration sensor 30 occurs, and the CPU 32 detects the unique change, whereby the pasting gesture is performed. It can be determined that it was performed. Further, for example, when the user 1 moves up the chin while wearing the headset 46, another unique change in the acceleration data from the acceleration sensor 30 occurs, and the CPU 32 detects the other unique change. Thus, it can be determined that the peeling gesture has been performed.

  In the embodiment, the location information (position or direction; orientation in the embodiment) when reproducing the tag data by moving the tag device 10 itself or the location information (position or direction when deleting the tag data). In the embodiment, the heading 46 is input. However, when the three-axis (or two-axis) geomagnetic sensor is built in the headset 46 of FIG. 13, the headset 46 is naturally used as the location information input means. can do.

  Furthermore, in the above-described embodiment, the position or direction where the sticky note should be pasted is designated by the absolute direction using the electronic compass. However, the position or direction of the tag may be a relative position or direction relative to the front of the user. For example, the front position of the face may be set to 0 °, and the pasting position may be specified with reference to that. However, when adopting such a relative position or direction, it is desirable to perform calibration (calibration) with the front of the face being 0 ° (or a specific angle) each time the sticky note device 10 is operated. Otherwise, there is a slight difference in the relative position or direction each time, and sticking of sticky note data with high density may cause confusion of the sticky note data.

  As an example of the front calibration operation, a method of moving the sticky note device 10 up and down with the sticky note device 10 placed in front of the user's face can be considered. That is, such vertical displacement may be detected by the acceleration sensor 30 built in the tag device 10 and the relative angle may be calibrated to 0 ° in response to the detection. However, when the acceleration sensor is built in the headset 46 shown in FIG. 14, the front calibration can be similarly performed by displacing the face of the user 1 up and down.

  Furthermore, in any of the above-described embodiments, a gesture (a sticking gesture, a peeling gesture, a front calibration gesture) is given to the sticky note device 10 itself or the user's head, and the acceleration signal from the acceleration sensor is unique. On the other hand, the CPU (computer) 32 detects the unique acceleration change to detect that the gesture has been performed, and identifies the type of the gesture.

  Such a gesture may be replaced with a voice gesture, or may be a combination of the operation of the sticky note device 10 or the operation of the user's head and the voice.

  In the case of only a voice gesture, for example, an utterance of 2 seconds or longer is defined as an affixed gesture, a voice with a pronunciation of “Sue” is defined as a peeling gesture, and the CPU 32 receives a signal from the microphone 20 (48: FIG. 14). These gestures can be detected by identifying the voice input.

  In addition, the peeling gesture in the above-described embodiment can be used as an undo gesture. Therefore, for example, when a peeling gesture is input immediately after a sticking gesture is input, the immediately following peeling gesture acts as a cancel gesture, and the sticking operation can be canceled.

  In the embodiment, when displaying the virtual space on the display device 14, no particular mention was made as to whether or not to display a background image. However, as shown in FIG. 15, a background image 52 is displayed and superimposed on the background image. .. And the tag icon objects 26a1, 26a2, 26a3,. However, in this case, it is necessary to pay attention to the following points.

  As described above, in order to reproduce or erase the sticky note data, the sticky note device 10 is rotated (moved) around the user's surrounding AR, and the sticking position or direction of the sticky note data in the virtual space is determined as the real space position. Or need to match the direction. When the sticky note device is rotated (moved), the position of the background image and the sticky note or the sticky note icon object may shift as shown in FIG. 16, but this is unnatural. Originally, the focal length of the lens of the camera 22 should be calibrated. However, not only is it time-consuming, but it is difficult to perform calibration in advance in consideration of various correspondences to the sticky note device 10. . Therefore, there is a need for a calibration method that can be easily performed by the sticky note device 10 each time.

  Accordingly, in another embodiment, as shown in FIG. 17A, several marks 54 and 56 (two in the embodiment) are displayed on the display 14, and these marks 54 and 56 are sequentially set in a predetermined manner. The sticky note devices 10 are sequentially arranged in the direction so as to be positioned, and each time the touch panel 16 (FIG. 15) is touched, the sticky note device 10 can individually perform calibration. When the change in the X-axis angle from FIG. 17B to FIG. 17C is dα and the distance between the two points is dx, the correspondence between them is dx = k1 × dα. Therefore, k1 = dx / dα can be calculated. If calibration is necessary also for the Y axis, if the distance dy between the two points and the angle change dβ are set, dy = k2 × dβ, and k2 = dy / dβ can be calculated. These coefficients k1 and k2 are correction coefficients for moving the tag object 26 and the tag icon object 26a on the display 14 when the tag device 10 is moved.

  Further, in the first embodiment described above, the triaxial geomagnetic sensor 28 and the triaxial acceleration sensor 30 built in the sticky note device 10 are used to input the sticking gesture and the peeling gesture. In the second embodiment, a triaxial geomagnetic sensor and a triaxial acceleration sensor built in the headset 46 (FIG. 13) are used. That is, it has been described that two sensors built in one apparatus are used in any of the embodiments in order to input a sticking gesture and a peeling gesture. However, for example, the geomagnetic sensor built in the tag device 10 and the acceleration sensor built in the headset 46 may be used in combination, or the acceleration sensor built in the tag device 10 and the headset 46 may be built. A combination of existing geomagnetic sensors may be used.

  That is, either the geomagnetic sensor built in the sticky note device 10 or the geomagnetic sensor built in the headset may be used as the position or direction indicating means for the sticking gesture or the peeling gesture, for the sticking gesture or the peeling gesture. Either an acceleration sensor built in the sticky note device 10 or an acceleration sensor built in the headset may be used as the instruction means for the sticking operation or peeling operation.

  Further, as the position or direction indicating means, if the GPS device is built in the sticky note device 10, position detection by the GPS unit may be used. In that case, for example, the sticky note data can be pasted or peeled off when moving a predetermined distance or at a predetermined intersection. As the position or direction instruction means, a wireless LAN position estimation function (for example, PlaceEngine: product name) can be used.

  And as a sticking operation | movement or peeling operation | movement instruction | indication means, you may make it utilize the touch panel 16 other than the acceleration sensor demonstrated in the Example, or may utilize an operation button (not shown). In this case, when a required position or direction is instructed by the position or direction instructing unit described above, an operation instruction may be input using these touch panels or operation buttons. Furthermore, voice input means such as a microphone may be used as the operation instruction input means. In that case, before or after instructing the position or direction of the gesture by the position or direction indicating means, or at the same time, by inputting a unique voice (voice) from the voice input means, a pasting operation instruction or a peeling operation instruction is input. You can do that.
