Description

  The present invention relates to an information search device using user life history information collected in a mobile terminal device. The life history information includes, for example, information related to the activity of the user of the mobile terminal device.

  Since mobile terminal devices having an Internet connection function have become popular, the number of websites that can be browsed by mobile terminal devices has increased, and services that provide various information in response to search requests from mobile terminal devices have also increased.

  As a general information search support technique, a technique is provided in which a history of keywords input by a user is stored and used when a keyword is input next. A push-type service is also provided in which the information provider distributes information reflecting user preferences by e-mail or the like based on information retrieved in the past (see Patent Document 1).

  By the way, in recent years, various additional functions using the characteristic of the mobile terminal device that the user always carries around are proposed. For example, according to the pedometer function added to the portable terminal device, it is possible to automatically collect step information when the user moves and use it for personal health management.

  However, information indicating a personal life history (hereinafter referred to as life history information) such as the step count information described above is referred to by an application for personal health management, for example, a message for health management. It is only used for creation.

  For this reason, for example, in order to use the collected life history information for information retrieval, the user must intentionally refer to the life history information and reflect it in a keyword for information retrieval, etc. In some cases, life history information was not fully utilized.

  An object of the present disclosure is to provide an information search device that can use life history information collected in a mobile terminal device.

  The above-described object can be achieved by an information search device disclosed below.

  Hereinafter, an embodiment of the information search apparatus of the present invention will be described based on the drawings.

  FIG. 1 shows the configuration of the mobile terminal device.

  The mobile terminal device includes a wireless transmission / reception unit 201, an audio processing unit 205, and a liquid crystal display unit 206. Each of these units is supplied with driving power from the power source unit 202 and is controlled by the CPU 210. A user of the mobile terminal device inputs an instruction via the keypad 207. In response to this instruction, the CPU 210 performs various processes such as a call process related to outgoing / incoming calls and a search process using the Internet connection function, and causes the memory unit 208 to hold necessary information at that time.

  In the configuration shown in FIG. 1, the audio signal output via the speaker 204 from the process of encoding the audio signal input via the microphone 203 and the encoded audio signal received via the wireless transmission / reception unit 201. The audio signal processing unit 205 is responsible for the process of reproducing the video.

  In addition, there is a model provided with a pedometer 209 as an additional function. In such a model, for example, the step count information obtained by the pedometer 209 is accumulated over one day in the CPU 210, and the daily accumulated result is the number of steps. It is stored in the memory unit 208 as an information history.

  Hereinafter, a method of using life history information including the above-described step count information for the search processing of the website will be described.

  FIG. 2 shows a configuration of an information search unit provided in the mobile terminal device.

  2 that are the same as those shown in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted.

  The radio control unit 211 illustrated in FIG. 2 controls the radio transmission / reception unit 201 in accordance with an instruction from the call control unit 212. As a result, the mobile terminal device establishes a communication channel with the radio base station, and receives services such as a telephone call and Internet connection.

  When using the Internet connection service, information for browsing a web page on the Internet is passed to the display control unit 215 via the browser unit 213 and used for display processing by the liquid crystal display unit 206. . In addition, the information search unit 214 creates search conditions for searching a web page in accordance with a user instruction input via the keypad 207, and passes the created search conditions to the browser unit 213 to perform information search processing. I do.

  Further, the step count information collection unit 216 shown in FIG. 2 collects the count results by the pedometer 209 once a day, for example, and stores the collected step count information in the life history information database 221 provided in the memory unit 208.

  The life history information database 221 can hold history information for each information type, for example, as shown in FIG. In the example shown in FIG. 3, the daily step count is retained as the history information of the step count information, and the keyword indicating the type of store included in a restaurant such as a restaurant or tavern is used as a related keyword corresponding to the step count information. A set is held. Further, in the life history information database 221, corresponding to the set of keywords, additional keyword candidates and additional keywords that are automatically added when searching using these keywords are included in the search conditions. The determination conditions for determining whether or not are registered. The keyword candidates that are automatically added are shown as additional keywords 1 and 2 in FIG. The life history information database 221 corresponds to a life history holding unit.

  The search control unit 218 provided in the information search unit 214 shown in FIG. 2 receives a search condition including a search keyword input by the user by operating the keypad 207 by the search instruction receiving unit 217. Referring to the life history information database 221, a search condition is created from the specified search keyword and additional keyword as described later.

  Hereinafter, a method for creating a search condition reflecting life history information using the life history information database 221 will be described.

  FIG. 4 is a flowchart showing an information search operation using life history information.

  When a search keyword is input, the search control unit 218 refers to the life history information database 221 (steps 301 and 302), and whether the input search keyword is registered as a related keyword corresponding to any information type. It is determined whether or not (step 303).

  For example, as illustrated in FIG. 5A, when the search keyword “restaurant” is input following the search keyword “Yokohama”, the search control unit 218 newly inputs the search keyword “restaurant”. Referring to the life history information database 221, it is detected that the search keyword “restaurant” is registered as a related keyword corresponding to the step count information.

  In this case, the search control unit 218 proceeds to step 304 as an affirmative determination of step 303 and refers to the step count information held in the life history information database 221. The search control unit 218 determines whether or not an additional keyword should be added to the search condition based on the determination information held corresponding to the step count information. For example, the search control unit 218 compares the total number S of steps over the last three days including today with a determination threshold (for example, 5000 steps), and when the total S is equal to or less than the determination threshold (negative determination at step 304). The user is likely to be lacking in exercise. Then, the search control unit 218 creates a search condition by adding the additional keyword “10 minutes or more on foot” (step 305).

  In response to this, as shown in FIG. 5, an additional keyword is displayed in addition to the input keyword, and an information search process is performed based on a search condition including this additional keyword (step 306).

  In the information search apparatus configured as described above, when a keyword associated with life history information is input, the search control unit 218 searches the life history information database 221 for life history information associated with the keyword. That is, the search control unit 218 performs a search process of the life history information database 221 in response to a keyword input, thereby realizing a function of history reference means for referring to life history information associated with a keyword.

  And the function of the determination means which determines the necessity to restrict | limit the information searched by the search control part 218 comparing the referred life history information with the determination conditions mentioned above is implement | achieved. In addition, when restriction is required, the search control unit 218 determines an additional keyword based on the comparison result between the determination condition and the life history information, and adds it to the input search condition. The function of an additional means for adding a search condition corresponding to is realized.

  Thereby, the search result narrowed down by the search condition to which the search result obtained corresponding to the keyword is added can be presented to the user.

  For example, the search condition specified by the user can be automatically adjusted based on the history of the step count information. As described above, by incorporating “10 minutes or more on foot” into the search condition, the search target store (in this case, a restaurant) or the like included in the search result is slightly away from the current location of the user. Limited to stores.

  Based on the collected life history information, by adding a suitable additional keyword to the search condition specified by the user and creating the search condition, for example, it is estimated that the user is in an exercise deficit state from the life history information In view of this, the life history information can be utilized for information retrieval using the Internet by adjusting the search conditions in a direction to eliminate lack of exercise.

  On the other hand, when the above-described total S exceeds the determination threshold value (Yes determination in Step 304), the search control unit 218 determines that addition of an additional keyword is unnecessary, and Step 305 is skipped and input. A search is performed using the search conditions created from the search keywords (step 306). In the case of negative determination in step 303, the above-described steps 304 to 305 are skipped, and similarly, the search is performed using the search condition created from the input search keyword (step 306).

  Note that the determination conditions and additional keywords registered in the life history information database 221 can be added or adjusted to reflect user preferences and the like.

  For example, as shown in FIG. 2, a new related keyword, determination condition, additional keyword based on a user instruction input via the keypad 207 by the related management unit 219 provided in the information search unit 214. Can be registered. For example, in FIG. 3, an additional keyword (“20 minutes or more on foot”) applied when the total number S of steps for three days is 2500 steps or less corresponding to a set of related keywords belonging to a restaurant corresponding to the step count information. , “Low calorie”) is registered. Also, corresponding to the step count information, a set of related keywords belonging to categories other than restaurants (showing an example in which a convenience store (convenience store) and a station are registered in FIG. 3) is registered, and corresponding to this set, Judgment conditions and additional keywords can also be registered.

  Further, when the number of steps is measured by an external pedometer and the number of steps is taken into the portable terminal device using a near field communication function such as an infrared communication function, the number of steps is similarly stored in the life history information database 221. It can be used for information retrieval. Moreover, cooperation with a blood pressure monitor, a heart rate monitor, etc. is also considered.

  Furthermore, the payment information at the convenience store and the payment information at the coffee shop are extracted from the payment information when using the payment function incorporated in the portable terminal device, and the history is stored in the life history information database 221 as life history information. You can also.

  For example, the payment history of a convenience store is collected for each convenience store chain (shown as symbols Ca and Cb in FIG. 3), and the collected payment history information is associated with the keyword “convenience store” in the life history information database 221. I can leave. In this case, if there is a chain in which the payment history is concentrated on one of the convenience store chains and there is a chain where the payment history is concentrated, a convenience store of a chain with a high payment frequency is added as an additional keyword. Additional keywords that are preferentially searched can be added.

  Similarly, the settlement history of the coffee shop is collected for each chain of the coffee shop (shown as symbols Ta and Tb in FIG. 3), and the collected settlement history information is associated with the keyword “coffee shop” in the life history information database 221. I can leave. In this case, whether or not the settlement history is biased toward any coffee shop chain is a criterion. If there is a chain where the settlement history is concentrated, priority is given to a coffee shop with a chain with a high settlement frequency as an additional keyword. An additional keyword to be searched can be added to.

  In this way, by using the tendency appearing in the life history information, the user's preference about the convenience store and the coffee shop can be automatically reflected in the information search.

  Also, using the camera function, meal history information such as calorie intake obtained by reading codes printed on restaurant menus and price labels on convenience store lunches, and consumption indicating calories consumed by training in fitness gyms, etc. The calorie history can also be held in the life history information database 221 as part of the life history information (see FIG. 3).

  Next, a method of creating a search condition using history information of a plurality of information types included in life history information will be described.

  FIG. 6 shows another flowchart showing an information search operation using the life history information.

  The search control unit 218 refers to the life history information database 221 in response to the input of the search keyword, and searches for information types in which the input search keyword is registered as a related keyword (steps 301 and 311).

  For example, as shown in FIG. 7A, by referring to the life history information database 221 shown in FIG. 3 in response to the input of the search keyword “restaurant”, the number of steps information history and the calorie consumption history as related information types Are retrieved, and an affirmative determination is made in step 312.

  As described above, when a plurality of related information types are searched, the search control unit 218 sequentially pays attention to each of the searched related information types, and a determination that is registered corresponding to the related information type of interest. Based on the conditions, life history information used for determination is extracted from the life history information database 221 (step 313). For example, when attention is paid to the step count information history, the search control unit 218 extracts the step count information history for three days including the current day from the life history information database 221, and based on this information, the corresponding determination condition (for example, It is determined whether or not “the total number S of steps for 3 days is 5000 steps or less” is satisfied (step 314).

  When the determination condition corresponding to the related information type of interest is satisfied (Yes determination in step 314), the search control unit 218 adds the additional keyword registered in the life history information database 221 corresponding to the related information type. (For example, “10 minutes or more on foot”) is held (step 315), and it is determined whether or not processing has been completed for all related information types (step 316).

  If there is a related information type that has not been processed yet (No in Step 316), the search control unit 218 returns to Step 313 and relates to the newly-related related information type (for example, calorie consumption history). Perform the process.

  In the processing focusing on the calorie consumption history, the search control unit 218 extracts the calorie consumption history for 3 days including the current day from the life history information database 221, and based on this information, the corresponding determination condition (for example, “3 days It is determined whether or not the total calorie consumption W is equal to or less than 2000 Kcal ”(step 314), and the additional keyword“ low calorie ”is held according to the positive determination in step 314 (step 315). ).

  When the processing for all the related information types is completed in this way (Yes in step 316), the search control unit 218 adds the additional keyword held in step 315 to the input search keyword and sets the search condition. Is created (step 317) and used for the search process of step 306.

  In the example shown in FIG. 7, the additional keywords “10 minutes on foot” and “low calories” are added based on the step count information history and the calorie consumption history, respectively.

  Further, as in the case of searching for a convenience store shown in FIG. 8, all the determination conditions for the related information type to be searched (for example, the step history information and the calorie consumption history) are established, and the additional keyword “10 minutes on foot” is set. The above and the additional keyword “20 minutes or more on foot” may be held as additional keyword candidates. In such a case, for example, the search control unit 218 can reflect the restriction by both additional keywords in the search condition by creating a search condition that limits the search range.

  In this way, when the user's life history information is used to search for store information, when the user's lack of exercise is revealed from the life history information, as shown in FIG. Even if there is a store A that can be reached within 5 minutes on foot in the vicinity of the location, it is possible to encourage the user's voluntary exercise by presenting store information of the store B that is at a distance of 20 minutes or more on foot.
