     SUMMARY 
     Problem to be Solved 
     Generally, it is difficult for people to accurately describe a smell to themselves or to others. This is because most people are not required to describe smells and thus they lack a working vocabulary to do so. Moreover, people tend not to able to clearly recognize a correspondence between a smell and a description to be used for the smell. This limitation also applies to describing taste. 
     It is thus an object of the present invention to provide via visual representation a relationship between a smell or a taste of an object and a verbal description of the smell or taste. 
     Solution 
     To solve the problems, according to one aspect of the invention, there is provided an information processing device including: a position specifying unit that specifies a location of an object that stimulates a user&#39;s sense of smell or taste; and a display control unit that displays, in a display area corresponding to the identified position of the object, one or more descriptions relating to the sense of smell or taste stimulated by the object, each of the descriptions being displayed by a predetermined appearance. 
     The display control unit may display the one or more descriptions by an appearance that corresponds to a relationship between the object and the one or more descriptions relating to the sense of smell or taste stimulated by the object. 
     The display control unit may display the one or more descriptions by an appearance that corresponds to a relationship between the user&#39;s preference for smell or taste and the one or more descriptions relating to the smell or taste stimulated by the object. 
     The display control unit may display the one or more descriptions in an appearance that corresponds to an attribute of the sense of smell or taste stimulated by the object. 
     The display control unit may display the one or more descriptions in an appearance that corresponds to the attribute of the one or more descriptions relating to the sense of smell or taste stimulated by the object. 
     When any of the one or more of the displayed descriptions is selected by the user, the display control unit may display a relational image, which is an image showing a relationship between the selected one or more descriptions and other objects that correspond to the sense of smell or taste associated with the one or more descriptions. 
     The display control unit may display the relational image by an appearance that accords with the sense of smell or taste associated with the selected one or more descriptions and the user&#39;s preference for the sense of smell or taste. 
     According to another aspect of the invention, there is provided a program for causing a computer to implement: a position specifying unit that specifies a location of an object that stimulates a user&#39;s sense of smell or taste, and a display control unit that displays, in a display area corresponding to the identified position of the object, one or more descriptions relating to the sense of smell or taste stimulated by the object, wherein each of the one or more descriptions is displayed by a predetermined appearance. 
     According to yet another aspect of the invention, there is provided an information providing system including: an input device; a display device; and an information processing device including an specifying unit that specifies a location of an object that stimulates a user&#39;s sense of smell or taste; and a display control unit that displays, in a display area corresponding to the identified position of the object, one or more descriptions relating to the sense of smell or taste stimulated by the object, each of the descriptions being displayed by a predetermined appearance. 
     Effect of the Invention 
     According to the present invention, a relationship between a smell or taste of an object and a verbal description of the smell or taste can be understood visually.

     DETAILED DESCRIPTION 
     Configuration 
     The overall configuration of the information providing system  1  according to one embodiment of the invention will now be described. The information providing system  1  is a system for providing information to enable a user to visually understand a relationship between a smell of an object and a verbal description of the smell. As shown in  FIG. 1 , the information providing system  1  includes an information processing device  10 , a projector  20 , a sensor  40 , and plural samples  60 . The information processing device  10 , the projector  20  and the sensor  40  communicate with each other via wired or wireless connections. The information processing device  10  is an example of an information processing device according to the present invention, and is a device that controls other devices in the information providing system  1 . The projector  20  is an example of a display device that displays information to a user. The sensor  40  is an example of an input device that receives an input from a user. Each of the plural samples  60  is an object that emits a smell that stimulates the user&#39;s sense of smell. For example, sample  60  may be a natural product that emits a smell (e.g., a lavender plant) or an artificial product that contains the smell of lavender (e.g., an extract of lavender in volatile liquid form, a sheet impregnated with the liquid, or the like). In this embodiment, the sample  60  is a cylindrical vial that is sealed with a lid and contains a liquid in the form of an extract oil that emits a smell of a natural product. Each sample  60  has a label or tag that includes the name of the sample (e.g., the name of the plant “lavender”). By referring to the label or tag name, the user is able to visually identify each sample. 
       FIG. 2  is a side view illustrating a structure of the information providing system  1 . More specifically,  FIG. 2  is a view illustrating a positional relationship of the projector  20 , the sensor  40 , and the sample  60  as viewed from a horizontal direction. The sensor  40  is constituted of, for example, a thin rectangular plate, an upper surface of which is a flat sensing surface. The sample  60  has a tag  61 , which is a storage medium for storing identification information (hereinafter referred to as a “sample ID”) for specifying each sample  60 . When the sample  60  is placed on the sensing surface, the sensor device  40  reads the sample ID stored in the tag  61  of the sample  60  by using, for example, a short-range wireless communication standard, referred to as Near Field Communication (NFC), and detects the position where the sample  60  is placed (i.e., the position where the tag  61  is read on the sensing surface). The sensor device  40  also functions as a touch screen, and for example, when the sensing surface is touched by a user&#39;s finger or a predetermined stylus, the touched position on the sensing surface is detected. The position where the sample  60  is placed or the position at which it is touched by the user is described as X, Y coordinates in a two-dimensional coordinate plane wherein a specified position of the sensing surface serves as an origin. 
     The projector  20  is installed above the sensor  40  (for example, on a ceiling of a room). As indicated by the dashed line in  FIG. 2 , the projector device  20  covers an entire area of the sensing surface of the sensor  40 , and is capable of projecting an image to any position on the sensing surface defined by the above X, Y coordinates. In other words, the sensing surface of the sensor device  40  also functions as a display surface on which an image is displayed. 
       FIG. 3  is a diagram illustrating a hardware configuration of the information processing device  10 . The information processing device  10  is a computer that includes a CPU (Central Processing Unit)  101 , a ROM (Read Only Memory)  102 , a RAM (Random Access Memory)  103 , an auxiliary storage device  104 , and a communication IF (Interface)  105 . 
     The CPU  101  is a processor that performs various operations. The ROM  102  is a non-volatile memory that stores, for example, a program and data used for booting the information processing device  10 . The RAM  103  is a volatile memory that functions as a work area when the CPU  101  executes the program. The auxiliary storage device  104  is a non-volatile storage device such as, for example, a HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores a program and data used in the information processing device  10 . By executing the program, the CPU  101  realizes the functions described below and also executes the operations described below. The communication IF  105  is an interface that performs communication in accordance with a predetermined communication standard. The communication standard may be a standard for wired communication or a standard for wireless communication. In addition to the configuration illustrated in  FIG. 3 , the information processing device  10  may include other elements, such as, for example, a display device such as a liquid crystal display and an input device such as a keyboard. 
     The auxiliary storage device  104  stores a description database (hereinafter, simply referred to as a description DB) as shown in  FIG. 4 . In the description DB, each sample ID includes one or more descriptions (i.e., one or more descriptions that describe the smell of the sample  60 , and are displayed as characters) that describe the smell sense stimulated by the sample  60  in correspondence with the sample ID. In other words, the description acts to convey a smell of the sample  60  to others when the user smells the smell of the sample  60 . The description may consist of any component part of language, such as, for example, a noun or an adjective; and may also include direct and indirect descriptions of the smell. Here, a direct description is one that is customarily used to evoke a sense of a smell, such as “sweet” or “fruity,” for example, while an indirect description is one that is not customarily used to describe a smell, such as “spring,” “morning,” or “walk.” Indirect descriptions may function as descriptions that are secondary and complementary to direct descriptions. Indirect descriptions may also consist of abstract terms. 
     Further, the Description DB includes appearance information for displaying each description. The appearance information includes information corresponding to, for example, a position at which the description is displayed relative to smell from an object (sample  60 ), the distance between the position at which the description is displayed and the sample  60 , the direction of the display position of the description relative to the sample  60 , the color in which the description is displayed, the size at which the description is displayed, the font with which the description is displayed, the modification with which the description is displayed, the time at which the description is displayed, the time period of displaying the description, the movement of the description (including spatial or temporal changes of the description), or the language used for the description, and so on. 
     This display information depends on a relationship between the sample  60  and its description. The relationship between the sample  60  and its description consists of an intensity and an amount of a smell (more specifically, components contained in the smell of the sample) as described by the description of the sample  60 ; or a level of abstraction of the description relative to the smell. For example, the description “sweet” may be displayed proximate to a sample  60  that has a strong sweet smell, or the description “sweet” may be prominently displayed in large characters or in a strong color on the sample  60  that has a strong sweet smell, or the description “sweet” may be prominently displayed on the sample  60  that has a strong sweet smell by movement as in vibration. Also, for example, for a sample that has both a strong sweet smell and a weak fruity smell, the description “sweet” may be displayed proximate to the sample, while the description “fruity” may be displayed farther away from the sample. This is an example of an appearance that changes dependent on a relationship between the sample  60  and its description. In addition, when a direct description and an indirect description are associated with a particular sample, a distance between the sample  60  and its description may be changed dependent on a level of abstraction of the description, such that a direct description is displayed proximate to the sample and an indirect description is displayed farther away from the sample this is also an example of an appearance that changes dependent on a relationship between the sample  60  and its description. In short, a description is displayed as visual information such that a relationship between the sample  60  and its description (specifically, a strength of a relationship and a characteristic of the relationship) are displayed for ease of visual recognition. 
     In the example shown in  FIG. 4 , the sample  60  having the sample ID “ID001,” “sweet” is recorded as description 1, “fresh” is recorded as description 2, and “flower” is recorded as description 3, and so on. Among these descriptions, the visual information of the description 1, “sweet,” has the following characteristics: a distance between the position at which the description is displayed and the sample is “2 units” (1 unit is a length determined in relation to the sensing surface), the color is “red,” the font is “Gothic,” the size is “25 points,” and the movement is “blinking.” 
       FIG. 5  is a block diagram showing an exemplary functional configuration of the information processing device  10 . In the information processing device  10 , the functions of a sample identification unit  11 , a location identification unit  12 , a description DB storage unit  13 , and a display control unit  14  are implemented. 
     When a sample  60  is placed on the sensing surface of the sensor (device)  40 , the sample specifying unit  11  specifies the sample  60  that is placed on the sensing surface based on the read sample ID stored in the tag  61  of the sample  60 . 
     When the sample  60  is placed on the sensing surface of the sensor (device)  40 , the position specifying unit  12  specifies the position on the sensing surface at which the sample  60  is placed (i.e., the position at which the sample  60  is placed on the sensor (device)  40 ) based on the position at which the sample ID stored in the tag  61  of the sample  60  was read (i.e., the position at which the operation to place the sample  60  was performed on the sensor (device)  40 ). In addition, when the sensing surface of the sensor (device)  40  is touched by a user, the position-specifying unit  12  specifies a position of the sensing surface that was touched. 
     The display control unit  14  controls the projector (device)  20  to display one or more descriptions of the sense of smell stimulated by the sample  60  identified by the sample identification unit  11  in the display area corresponding to the position of the sample  60  identified by the position identification unit  12 . At this time, the display control unit  14  displays the descriptions in accordance by the appearance information that corresponds to the samples identified by the sample identification unit  11  in the description DB that is stored in the description DB storage unit  13 . The display area corresponding to the position of the sample  60  is, for example, an area on the sensing surface that is within a determined distance from the position of that sample  60 , and a specific example, is a circular area within a radius of  10  centimeters centered at a position of the sample  60  on the sensing surface. However, the display area corresponding to the position of the sample  60  is not limited to this example, and may be an area that a user is able to recognize as a sample to which the displayed description relates. 
     Further, when any of the one or more displayed descriptions is selected by the user, the display control unit  14  displays a related image, which is an image that shows a relationship between the selected description and other samples  60  corresponding to the olfactory sensation associated with the description, as will be described in detail later with reference to  FIG. 10 . 
     Operation 
     An exemplary operation of the present embodiment will now be described with reference to the flowchart shown in  FIG. 6 . First, the user selects samples  60  of interest by referring to the names of the samples shown on the samples  60 , and places the samples on the sensing surface of the sensor  40 . 
     In  FIG. 7  a plan view is shown that illustrates from above a view of the sensing surface of the sensor  40 . In this example, seven samples  60   a  to  60   g  are placed on the sensing surface of the sensor  40 . At this time, the sample specifying unit  11  of the information processing device  10  specifies (at step S 11  in  FIG. 6 ) which sample(s)  60  is/are placed on the sensing surface based on the reading of the sample ID by the sensor  40 . Further, the location specifying unit  12  of the information processing device  10  specifies (at step S 12 ) for each sample  60  the position at which the sample  60  is placed on the sensing surface based on the reading position of the sample ID by the sensor  40 . At this step, it is identified that the samples  60   a  to  60   g  have been placed at the respective positions illustrated in  FIG. 7 . The order of the processing at steps S 11  and S 12  may be changed from those of the example in  FIG. 6 , or the processes may be performed substantially simultaneously. 
     Among samples  60   a  to  60   g  placed on the sensing surface of the sensor (device)  40 , the user selects a sample (here, sample  60   g ), for which the user wishes to know a description relating to a smell of the sample, and places the selected sample at a predetermined position on the sensing surface. The predetermined position is a closed area indicated by a dashed line image displayed on the sensing surface by the projector (device)  20  as shown in  FIG. 7 , and is referred to as an “analysis target position A.” The position, shape, and size of the analysis target position A may be determined at will, but it is necessary for the user to know or to be informed in advance by means of display, voice guidance, or the like an area on the sensing surface that is the analysis target position A. 
     As shown in  FIG. 8 , the sample  60   g  is placed at the analysis target position A on the sensing surface. At this time, the position specifying unit  12  determines that the sample  60   g  is at the analysis target position on the sensing surface (at step S 13  in  FIG. 6 ; YES). It is of note that regarding the state shown in  FIG. 7 , since the position specifying unit  12  determines that none of the samples  60  is at the analysis target position on the sensing surface (at step S 13  in  FIG. 6 ; NO), the process remains in a standby state while the process (at step S 11 ) relating to the identification of the samples  60  and the process (at step S 12 ) relating to the identification of the position of the samples  60  are performed. 
     When it is determined that the sample  60 G is in the analysis target position, the display control unit  14  searches (at step S 14  in  FIG. 6 ) for descriptions corresponding to the sample ID in the description DB, by using the sample ID of the sample  60 G as a search key. Further, the display control unit  14  determines (at step S 15  in  FIG. 6 ) an appearance corresponding to each of the searched descriptions by referring to the description DB. Then, the display control unit  14  controls the projector (device)  20  to display (at step S 16  in  FIG. 6 ) the descriptions retrieved at step S 14  in the display area corresponding to the position of the sample  60   g  identified by the position identification unit  12 , in accordance by the appearance determined at step S 15 . 
     According to the above processes, the descriptions relating to the smell of the sample  60   g  are displayed, for example, inside a circle centered on the position of the sample  60   g,  and having a size as illustrated in  FIG. 9 . At this time, each description is displayed by an appearance that corresponds to the relationship between the description and the sample  60   g,  as described above. By opening the lid of the sample  60   g  and smelling the smell of the sample  60   g  while viewing descriptions, the user is able to determine how to describe the smell of the sample  60   g.  At the same time, the user is also able to determine the relationship between the smell of the sample  60   g  and each description by referring to the appearance with which each description is displayed. For example, in the example shown in  FIG. 9 , the user can see that the smell of the sample  60   g  is a smell that is typically described as “sweet,” but also contains smell components that are described as “fresh,” “gorgeous,” “relaxing,” “mellow,” “flower,” and “fruit,” and also that these smells can be used to describe “spring,” “morning,” “ pink,” “walk,” and “light,” and are associated with such concepts. 
     Further, if there is a description among the displayed group of descriptions that the user is interested in or wishes to better to understand, the user selects the description by touching the description displayed on the sensing surface. When the user touches the description (at step S 17  in  FIG. 6 ; YES), the display control unit  14  specifies the description selected by the user based on the position touched by the user and a display position of each of a description. At this time, it is preferable to display the description with a specific background color, or to highlight the description so that the user can easily identify which description has been selected. 
     Then, the display control unit  14  searches, in the description DB, for a sample ID that is associated with the selected description among the group of sample IDs identified at step S 11 . If a sample ID that is associated with the selected description is found by the search, the display control unit  14  determines that a sample related to the selected description is to be placed on the sensing surface (at step S 18 ; YES), and controls (at step S 19 ) the projector (device)  20  to display a relational image. The relational image is, for example, a line-shaped image connecting a display position of the description selected by the user via the sensing surface and at a position where the sample corresponding to the found sample ID is placed. 
     According to the above processes, relational images R 1  and R 2  connected with the description “sweet” are selected by the user along with other samples described by the description “sweet” (here, samples  60   a  and  60   d ) are displayed, as illustrated in  FIG. 10 . From these relational images R 1  and R 2 , the user can see that, in addition to the sample  60   g,  there are also samples  60   a  and  60   d  that correspond to smells described as “sweet.” 
     Appearances such as color, thickness, size, movement, etc., of the relational image are based on the relationship between the description selected by the user and the other samples described by the description. For example, when the relationship between the description selected by the user and the other samples described by the description is strong, a color, thickness, size, movement, etc. are displayed in such a way that the relational image is more prominent, and vice versa when the relationship is weak. In the example shown in  FIG. 10 , since the sample  60 d has a strong relationship to the description “sweet,” the relational image R 1  connecting the description “sweet” and the sample  60   d  is depicted as a thicker image than the relational image R 2  connecting the description “sweet” with the sample  60   a.  The relationship between the description selected by the user and the other samples described by the description is determined based on the appearance determined in the description DB. In the example shown in  FIG. 10 , the appearance corresponding to the description “sweet” and the sample  60   d  in the description DB is one used when the relationship is stronger than that of the appearance corresponding to the description “sweet” and the sample  60   a.    
     If the user wishes to obtain further information about another description, the user can obtain such information by touching another description on the sensing surface (at step S 20 ; NO). If the user touches another description, the above steps S 17  to S 19  are executed for the another description. Then, if the user wishes to know the description for the new sample  60 , the user performs (at step S 20 ; YES) the predetermined operation to terminate the process and replaces the sample at the analysis target position A. As a result, the above steps S 11  to S 19  are repeated for another description. In this way, the user can try various samples of smells and view their corresponding descriptions. 
     The above-described embodiment enables a user to understand a visual relationship between a smell of an object and a description of its smell. 
     Modifications 
     The present invention is not limited to the above described embodiments. The above described embodiments may be modified as follows. Further, two or more items described in the following modifications may be combined. 
     First Modification 
     The present invention is applicable not only to olfactory objects but also to gustatory objects (e.g. wine, Japanese rice wine, spices, seasonings, and so on.). In other words, the present invention may be implemented by replacing smell in the embodiments with taste. 
     Second Modification 
     The appearance of each displayed description may be determined in accordance with a relationship between the description and the user who views the displayed description. The relationship between the description and the user includes, for example, a degree of agreement between the smell described by the description and the user&#39;s preference for the smell, and a history of the user&#39;s use of the description as a description of the smell. For example, for a user who prefers a “sweet” smell, an example of the description “sweet” is displayed proximate to the sample  60  at the analysis target position A, with the description “sweet” displayed in a large format or a strong color, or the description “sweet” is displayed in a conspicuous manner by use of movement such as vibration. In this case, user preferences for smells are collected and stored in a database in advance in an auxiliary storage device  104  or the like, and the display control unit  14  refers to the database. 
     For example, for a user who has frequently used the description “sweet” in the past, the description “sweet” is displayed proximate to the sample  60  placed at the analysis target position A, or the description “sweet” displayed in a conspicuous manner by use of movement such as vibration. In this case, a history of descriptions used by the user to describe the smell is collected in advance and stored in a database in the auxiliary storage device  104  or the like, and the display control unit  14  refers to the database. 
     Third Modification 
     The appearance by which each description is displayed may be determined in accordance with an attribute of the smell described by the description. The attributes of a smell may include, for example, a top note, a middle note, or a lower note, the strength/weakness of the stimulus of the smell, and the degree of interest, specialness, or rarity of the smell. The top note, the middle note, and the lower note of the smell may change over time, for example, when a first smell is recognized, a next smell is recognized, and then a further next smell is recognized. For instance, there can be envisaged an example of displaying descriptions corresponding to a top note, a middle note, and a lower note in order or distance from a position ranging from proximate to far from the sample  60  placed at the analysis target position A; or an example of switching the display of descriptions corresponding to a top note, a middle note, and a lower note in chronological order may be applied. In addition, an example in which descriptions that relate to highly stimulating smells or rare smells are displayed in a specific color, font, or movement, may be applied. 
     Fourth Modification. 
     The appearance in which each description is displayed may be determined in accordance with an attribute of the description. The attributes of the description include, for example, an image corresponding? to the description, a language component of the description, a character (Japanese hiragana, Japanese katakana, Japanese kanji, alphabet, etc.) used in denoting the description, a number of characters/words constituting the description, and the like. For example, the description “sweet” may be displayed in a warm color. 
     Fifth Modification 
     When displaying the relational image (see  FIG. 10 ), the display control unit  14  may display the relational image by an appearance in accordance with a user&#39;s preference for the smell described by the description selected by the user on the sensing surface. For example, in the relational image connecting the description “sweet” selected by the user and the other samples described by the description, the appearance such as the color, thickness, size, movement, etc. thereof is changed according to the user&#39;s preference for the “sweet” smell. Specifically, if the user prefers a “sweet” smell, the color, thickness, size, movement, etc. of the relational image may be made more prominent. In this case, the user&#39;s preferences for smells are collected and put into a database in advance and stored in the auxiliary storage device  104  or the like, and the display control unit  14  refers to the database. The relational image is not limited to the linear image illustrated in  FIG. 10 , and may be any image that shows that the description selected by the user and the sample described by the description are related. For example, a first circular image enclosing the description “sweet” selected by the user and a second circular image enclosing the position of the other sample  60  described by the description “sweet” may be used as the relational image. 
     Sixth Modification 
     The display device and the input device are not limited to the projector (device)  20  and the sensor (device)  40  illustrated in  FIG. 1 . For example, the display(device)  20  is not limited to a device that projects an image onto the sensing surface of the sensor (device)  40 , which is an input device, as described in the embodiments. However, for example, the input device itself may be a display device. The display device may also be a device that displays an image on a wall surface (including cases where the image is projected onto the wall surface or where the wall surface itself is a display). The display device may also be a display device that realizes so-called augmented reality. Specifically, when the sample  60  is captured by an imaging device of a smartphone, tablet, or glass-type wearable device, a corresponding group of descriptions may be displayed around the sample  60  in the captured image. The input device may be a device that detects a user&#39;s operation by use of image recognition technology. 
     Seventh Modification 
     In the embodiment, where the sample  60  is placed at the analysis target position A to be analyzed, a description related to the sample  60  is displayed. However, for example, a description related to the sample  60  may be displayed if the user opens the lid of a small bottle containing aromatic oil corresponding to the sample  60 . Similarly, for example, a natural object may be placed on a plate and covered with a transparent cover, and if the user removes the transparent cover, a description related to the smell of the natural object may be displayed. 
     Eighth Modification 
     Not only one sample  60  may be placed at the analysis target position, and plural samples may be placed there at the same time. In this case, a description for each of the samples will be displayed in a display area corresponding to the position of each of the samples  60 . 
     Ninth Modification 
     The visual appearance of the displayed description may be two-dimensional or three-dimensional. The displayed “description” is not limited to text, and may also be a color, an abstract form, or an image such as of that of a person/scene. 
     The present invention may be provided as an information processing method that includes processing steps executed by the information processing device  10 . The present invention may also be provided as a program that is executed by the information processing device  10 . Such a program may be provided on a recording medium such as an optical disk, or may be provided via a network such as the Internet, and then installed and executed on the computer.
