  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing a schematic configuration of a mobile terminal 1 to which an information processing apparatus according to an embodiment of the present invention is applied. The portable terminal 1 includes a control unit 10, a power supply circuit unit 11, a display unit 12, an operation unit 13, a voice control unit 14, a wireless communication unit 15, a storage unit 16, an information storage medium 17, a time information acquisition unit 18, and a feature value acquisition. The unit 19, the position information calculation unit 20, the condition table storage unit 21, and the data table storage unit 22 are configured to be communicable with each other via a bus.

  The power supply circuit unit 11 includes a power supply source (battery or the like), switches the power supply ON / OFF state of the portable terminal 1 based on an input via the operation key of the operation unit 13, and power when the power supply is in the ON state. Electric power is supplied from the supply source to each unit, and the portable terminal 1 is made operable.

  The display unit 12 is a monitor or the like, and displays document data, image data, and the like based on the control of the control unit 10. The operation unit 13 is an input device such as a touch panel or operation keys.

  The sound control unit 14 generates an analog sound signal from the sound collected by the microphone 141 based on the control of the control unit 10, and converts the analog sound signal into a digital sound signal. Further, when acquiring the digital audio signal, the audio control unit 14 converts the digital audio signal into an analog audio signal based on the control of the control unit 10, and outputs the analog audio signal from the speaker 142.

  Based on the control of the control unit 10, the wireless communication unit 15 performs spectrum despreading processing on the received signal received from the base station via the antenna 15 a to restore data. This data is transmitted to the sound control unit 14 and output from the speaker 142, transmitted to the display unit 12 for display, or recorded in the storage unit 16 according to an instruction from the control unit 10. In addition, when the wireless communication unit 15 acquires sound data collected by the microphone 141, data input by the operation unit 13, or data stored in the storage unit 16 based on the control of the control unit 10, Spread spectrum processing is performed on the data, and the data is transmitted to the base station via the antenna 15a. The wireless communication unit 15 includes a GPS (Global Positioning System) receiving unit 151, receives GPS signals from satellites and GPS base stations, and calculates position information by a position information calculation unit 20 described later.

  The time information acquisition unit 18 acquires information on a clock in the mobile terminal 1. Alternatively, the time information acquisition unit 18 may acquire date and time information from the base station of the mobile terminal 1. The feature value acquisition unit 19 acquires a feature value such as a maximum value or an average value of each axis, for example, for the x-axis, y-axis, and z-axis values detected by the acceleration sensor 191 within a predetermined time. This feature value is used to estimate the movement situation (for example, “still”, “walking”, “vehicle”) of the user holding the mobile terminal 1 using a neural network. Details will be described later. The location information calculation unit 20 measures the distance to the satellite based on the satellite received by the GPS reception unit 151 in the wireless communication unit 15 and the GPS signal from the GPS base station, and the location information (latitude, longitude) of the mobile terminal 1 itself. ) Is calculated.

  The storage unit 16 serves as a work area for the control unit 10 and the wireless communication unit 15, and its function can be realized by a RAM (Random Access Memory) or the like. In addition, data is temporarily stored.

  The information storage medium 17 (a computer-readable medium) stores programs, data, and the like, and its function can be realized by a hard disk, a memory (ROM: Read Only Memory), or the like. The information storage medium 17 stores a program for causing a computer to function as each unit of the present embodiment (a program for causing a computer to execute processing of each unit), a plurality of applications, and the like.

  The control unit 10 includes a CPU (Central Processing Unit), and is an arithmetic device that performs overall control of the mobile terminal 1 and performs various other arithmetic processes and control processes. The function of the control unit 10 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs. The control unit 10 performs various processes of the present embodiment based on a program (data) stored in the information storage medium 17.

  The condition table storage unit 21 includes a plurality of “conditions” (condition A, condition B, etc.) set from combinations of items related to a plurality of situations such as date / day of the week, time zone, place, movement status, and display priority, and presentation information. The table (condition table) is stored. The presentation information displayed on the mobile terminal 1 is different for each “condition”. The display priority is an item indicating the order of the conditions for displaying the presentation information first when there is a duplicate setting content in all items regarding the situation among a plurality of conditions. An example of the condition table is shown in FIG. In FIG. 2, condition A is a setting for displaying “schedule, news, clock” on the display unit 12 as presentation information when “moving by vehicle” from “6:00 to 9:00” on “Monday”. . The condition B is set to display “news, clock” on the display unit 12 as presentation information when “moving by vehicle” from “8:00 to 10:00” on “Tuesday, Wednesday, Thursday, Friday”. It is. In condition A and condition B, only one item related to the situation overlaps, so the display priority is set to “1” for both conditions.

  The data table storage unit 22 stores a location table in which the latitude and longitude calculated by the location information calculation unit 20 and the location are set as shown in FIG. The location table is data that is the source of the location item in the condition table in the condition table storage unit 21. The data table storage unit 22 stores movement status data indicating the relationship between the feature value range and the corresponding movement status. Details will be described later. The data table storage unit 22 stores data acquired by a situation data acquisition unit 101 in the control unit 10 to be described later, estimated by the situation estimation unit 102, and determined by the presentation information determination unit 103, respectively. Details will be described later.

  FIG. 3 shows a location table in which locations of “company” and “home” are set as an example. When the user performs an operation of registering the current location as a company or home position using the operation unit 13 of the mobile terminal 1, the GPS reception unit 151 receives a GPS signal from a satellite. The position information calculation unit 20 calculates the latitude and longitude based on the GPS signal received by the GPS reception unit 151. The control unit 10 registers the latitude and longitude calculated by the position information calculation unit 20 as a company or a home. In addition, the control unit 10 sets an effective distance as to which distance range from the latitude and longitude of the registered place is regarded as the registered place. This is because, for example, when the company site is large, the user who owns the mobile terminal 1 is in the company site, but the distance is longer than the registered latitude and longitude, so the mobile terminal 1 is not in the company. This is to prevent the annoyance of being regarded as being presented information.

  The control unit 10 includes a situation data acquisition unit 101, a situation estimation unit 102, a presentation information determination unit 103, and an information switching detection unit 104.

  The situation data acquisition unit 101 acquires data related to the usage status of the mobile terminal 1. The status data acquisition unit 101 acquires data on the usage status when the screen of the display unit 12 is lit. The acquired data is, for example, the feature value obtained by the feature value obtaining unit 19, the position information calculated by the position information calculating unit 20, and the time information obtained by the time information obtaining unit 18, and is stored in the data table storage unit 22. .

  The situation estimation unit 102 determines the date / time and location of the mobile terminal 1 based on the data regarding the usage status of the mobile terminal 1 acquired by the status data acquisition unit 101 and the location table stored in the data table storage unit 22 in advance. Etc. are estimated. In addition, the situation estimation unit 102 estimates the movement situation of the user holding the mobile terminal 1 using a neural network based on the feature value acquired by the feature value acquisition unit 19.

  FIG. 4 is an example of movement status data indicating a movement status that becomes “correct answer data” for a specific feature value range. The neural network performs learning based on these movement state data, and determines an operation parameter used when estimating an arbitrary feature value as a movement state. When the feature value acquisition unit 19 acquires the feature value, the situation estimation unit 102 estimates the movement state using this parameter. The movement status data is stored in the data table storage unit 22 as described above. The estimated situation (date and time, location, movement situation, etc.) is stored in the data table storage unit 22 as an estimation result.

  The presentation information determination unit 103 collates the situation (estimation result) of the mobile terminal 1 estimated by the situation estimation unit 102 with the condition table stored in the condition table storage unit 21, and matches the estimation result. Alternatively, the condition closest to the estimation result is determined. The determined condition is stored in the data table storage unit 22.

  In the information switching detection unit 104, the condition determined by the presentation information determination unit 103 and displayed on the display unit 12 (condition A: first condition) is displayed by the user under other conditions (condition B: second condition). , It is detected that the first condition has been switched to the second condition.

  The estimated value changing unit 105 changes the movement status data stored in the data table storage unit 22 and used for situation estimation or the setting value of the location table. The condition change unit 106 changes the setting value of the condition table stored in the condition table storage unit 21.

<Determination of conditions based on estimation results>
Next, the operation of determining the condition based on the estimation result in the mobile terminal 1 having the above configuration will be described with reference to the table of FIG. 5 and the flowchart of FIG.

  The user inputs and sets a plurality of conditions for causing the display unit 12 to display desired presentation information using the operation unit 13. The control unit 10 stores the input conditions as a table in the condition table storage unit 21 (step S101). In this embodiment, it is assumed that the condition table shown in FIG. 2 is stored in the condition table storage unit 21.

  Assume that the mobile terminal 1 is currently in the situation shown in FIG. 5A (time: Friday, July 10, 2009, place: near H town, movement situation: train). The situation data acquisition unit 101 periodically acquires data related to the usage status of the mobile terminal 1 acquired by the time information acquisition unit 18, the feature value acquisition unit 19, and the position information calculation unit 20 (step S103). In this embodiment, an operation for determining a condition based on the feature value acquired by the feature value acquisition unit 19 will be described.

FIG. 5B shows the feature value C ₁ acquired by the situation data acquisition unit 101 from the feature value acquisition unit 19 and the time acquired by the situation data acquisition unit 101. The feature value data and the acquired time are stored in the data table storage unit 22.

The situation estimation unit 102 can estimate the movement situation among the items in the condition table based on the feature value data. State estimation unit 102, the feature value C ₁ which situation data acquiring unit 101 acquired in step S103, using a neural network performing the learning based on the moving condition data shown in FIG. 4, a moving state as "vehicle" Estimate (step S105). FIG. 5C shows an estimation result related to the movement situation estimated by the situation estimation unit 102. The situation estimation unit 102 stores the estimation result, the acquisition data obtained by the situation data acquisition unit 101 used for the estimation, the time when the data used for the estimation is acquired, and the estimation result calculation time shown in FIG. Store in the table storage unit 22.

  Next, the situation estimation unit 102 presents the estimation result (FIG. 5 (c)) regarding the movement status estimated in step S105 and the data (date / time, day of week, location, etc.) regarding the usage status of the mobile terminal 1 acquired in step S103. The information determination unit 103 is notified (step S107). The presentation information determination unit 103 receives the condition table (FIG. 2) stored in the condition table storage unit 21, the data regarding the usage status of the mobile terminal 1 notified in step S <b> 107 and the estimation result of FIG. 5 (c). Collation is performed (step S109). Then, the presentation information determination unit 103 determines the condition that matches the estimation result or the closest condition based on the table in the condition table storage unit 21 (step S111). FIG. 5D shows a determination result in the presentation information determination unit 103. In FIG. 5C, since the day of the week is “Friday”, the estimation result is “vehicle”, and the estimated time is between 8:00 and 10:00, the presentation information determination unit 103 stores the table in the condition table storage unit 21 shown in FIG. To “condition B”. The presentation information determination unit 103 stores, in the data table storage unit 22, the determination result, the determination result calculation time, the estimated time of the data used for the determination, and the condition table item used for the determination shown in FIG. To do.

  Next, the control unit 10 causes the display unit 12 to display the presentation information “news, clock” corresponding to the condition B determined in step S111 (step S113). In this way, the mobile terminal 1 displays appropriate information on the display unit 12 when the user needs, in accordance with the conditions set by the user.

  The display unit 12 displays the presentation information on the determined condition among the conditions described in the condition table on the front, displays the presentation information on the other conditions on the back, and the display can be switched by a user operation. May be displayed. A display example is shown in FIG. In FIG. 7, tab display is performed for each condition, and when the user selects another tab using the operation unit 13, the condition is switched to another condition.

  However, there is a case where information desired by the user is not presented because the estimation is not correct. Or, while the user is using the mobile terminal 1, it is conceivable that the user first notices that the condition set first is not appropriate and switches to presentation information under other conditions. In such a case, the control unit 10 of the mobile terminal 1 can automatically change the setting, and the user can reset the setting without inputting the condition again. The control unit 10 changes the data table (location table or movement status data in the present embodiment, which will be collectively referred to as a status table hereinafter) stored in the data table storage unit 22 used when deriving the estimation result. Or the condition set in advance by the user and stored in the condition table storage unit 21 is changed. This will be described below.

<Change status table>
The operation when changing the situation table (location table, movement situation data) used when determining the estimation result will be described with reference to the example of the table of FIG. 8 and the flowchart of FIG. In this embodiment, a case where the movement status data is changed will be described.

From FIG. 8, the feature value obtaining unit 19 of the portable terminal 1 is acquired, the current characteristic value and A _3. The current situation of the mobile terminal 1 is estimated by the situation estimation unit 102 as “time: 8:30, place: K station, movement situation: stationary”, and the presentation information determination unit 103 determines that the condition X “time: From 6 o'clock to 8 o'clock, it is determined that the movement state is stationary, and the display unit 12 displays the presentation information “news, clock, weather” corresponding to the condition X (step S201). When the user switches the display of the presentation information corresponding to the displayed condition X to the presentation information corresponding to the condition Y using the operation unit 13 during this time period, the information switching detection unit 104 displays the display of the condition X on the condition X , It is detected that the presentation information corresponding to the condition Y has been switched (step S203). Here, the number of times of switching is counted for each switching condition. For example, when the condition X is “time: 6 to 8 o'clock, movement situation: stationary”, and the condition Y is “time: 6 o'clock to 8 o'clock, movement situation: vehicle”, the difference between the condition X and the condition Y Since the movement status is switched from “stationary” to “vehicle”, the switching condition “switch the movement status from stationary to vehicle” is counted up.

When the number of times the display switching from the condition X to the condition Y is detected in step S203 exceeds a predetermined number (for example, 5 times) (“Yes” in step S205), the information switching detection unit 104 moves to the presentation information determination unit 103. It is notified that the display switching to the condition Y has exceeded a predetermined number of times (step S207). The presentation information determination unit 103 compares the estimation result with the condition Y, extracts the estimation result “still” of the movement situation that does not apply to the condition Y, and notifies the situation estimation unit 102 of the result (step S209).

Then condition estimation unit 102, so that the moving condition of the "correct answer data" for the feature value A ₃ at this time is "vehicle", additionally writes the moving condition data (step S211). Then, the neural network is made to learn again based on the newly added movement status data.

  A case where the location table is changed will be described. The estimation result of the location based on the current situation of the mobile terminal 1 is “home”, and based on this, the condition that the presentation information determination unit 103 is determined is determined, but the user switches to another condition, and the location in the other condition Is not set to “Home”. In this case, assuming that the estimation result of “home” is incorrect, the estimated value changing unit 105 may change the location table and change the effective distance of “home” to a short distance.

<Change of condition item>
As another example, an operation of the mobile terminal 1 when a condition set by the user in advance (referred to as condition B) is changed on the mobile terminal 1 will be described with reference to the flowchart of FIG. Detects that the presentation information corresponding to condition B has been switched to presentation information corresponding to another condition (condition A) by the user, and notifies the presentation information determination unit 103 that the number of detections has exceeded a predetermined number The operations up to this are the same as the operations in steps S201 to S207 in FIG.

The presentation information determination unit 103 extracts the condition A corresponding to the presentation information whose display is switched by the user and the corresponding estimation result. The condition changing unit 106 changes the set value of the item in the condition A so that the condition A can be determined from the estimation result. At this time, when the setting values of all items (date / day of the week, time zone, location, movement status, etc.) other than the item to be changed are completely the same for both condition A and condition B ("Yes" in step S311) ), The condition changing unit 106 changes the setting values of the items to be changed in both the condition A and the condition B in both the condition A and the condition B (step S313). When the setting values of the items other than the item to be changed are different between the condition A and the condition B (“No” in step S311), the condition changing unit 106 changes the setting value of the item of the condition A (step S315), The priority of the switched condition is set higher than the initial setting (step S317).
Specific examples will be described below.

(1) When Date / Day of Week Item is Changed FIG. 11 shows an example of a condition table when the date / day of the week item is changed. FIG. 11A shows only the date / day of the week item setting values differ for each condition. The table before the change in the case, (b) is the table after the change. The current status of the mobile terminal 1 is estimated to be “Friday, 8:30, movement status: vehicle”. The presentation information determination unit 103 determines the condition B from the estimation result and the condition table (a). When the number of times the display can be switched to the condition A exceeds the predetermined number, the condition changing unit 106 changes the date item of the condition A from “Month” to “Month, Friday”, and the date item of the condition B “Tue, Wed” , “Thu, Fri” to “Tue, Wed, Thu”.

  FIG. 11C shows a pre-change table when the setting values of the date / day of week item and the time zone item differ for each condition, and FIG. 11D shows the post-change table. The current status of the mobile terminal 1 is estimated to be “Friday, 8:30, movement status: vehicle”. The presentation information determination unit 103 determines the condition B from the estimation result and the condition table (c). When the number of times the display can be switched to the condition A exceeds the predetermined number, the condition changing unit 106 changes the setting value of the date / day of week item of the condition A from “Month” to “Month, Friday”. Further, in this example, when this setting value change is performed, the condition A and the condition B are duplicated in all items related to the situation, so the condition changing unit 106 sets the presentation information corresponding to the condition A as a condition. In order to display before B, the display priority in condition A is increased by one.

(2) When changing the time zone item FIG. 12 is a condition table when changing the time zone item, and (a) is a table before change when only the time zone item has different settings for each condition. b) is a table after conversion. Similarly to FIG. 11A, the current situation of the mobile terminal 1 is estimated as “Friday, 8:30, moving situation: vehicle”, and is determined as condition B. When the number of times the display can be switched to condition A exceeds the predetermined number, the condition change unit 106 changes the condition A time item from “6: 00-8: 00” to “6: 00-8: 30” Change the setting value for the time item of B from “8: 00-10: 00” to “8: 31-10: 00”.

  FIG. 12C shows a pre-change table when the set values of the time zone and place items differ for each condition, and FIG. 12D shows a post-change table. The current situation of the mobile terminal 1 is estimated as “8:30, location: home, movement situation: stationary”, and is determined as condition B. When the number of times the display can be switched to condition A exceeds the predetermined number, the condition change unit 106 changes the setting of the condition A time item from “6: 00-8: 00” to “6: 00-8: 30” To do. In this example, the condition A and the condition B are set to overlap in all items related to the situation, so the condition changing unit 106 increases the display priority in the condition A by one.

(3) When changing a location item FIG. 13 is a condition table when changing a location item. (A) is a pre-conversion table when only the location item has different settings for each condition. It is the table after conversion. The current situation of the mobile terminal 1 is estimated as “8:30, place: station, movement situation: stationary”, and is determined as condition B. When the number of times the display can be switched to the condition A exceeds the predetermined number, the condition changing unit 106 changes the item of the location of the condition A from “home” to “home, station” and the item of the location of the condition B “station, company” Change the setting value from “Company” to “Company”.

  FIG. 13C shows a pre-change table when the set values of the time zone and place items differ for each condition, and FIG. 13D shows a post-change table. The current situation of the mobile terminal 1 is estimated as “8:30, place: station, movement situation: stationary”, and is determined as condition B. When the number of times the display can be switched to the condition A exceeds the predetermined number, the condition changing unit 106 changes the setting of the location of the condition A from “home” to “home, station”. In this example, the condition A and the condition B are set to overlap in all items related to the situation, so the condition changing unit 106 increases the display priority in the condition A by one.

(4) When changing the item of movement status FIG. 14 is a condition table when changing the item of movement status, (a) is a pre-conversion table when only the setting of the movement status item is different for each condition, ( b) is a table after conversion. The current situation of the mobile terminal 1 is estimated as “8:30, place: station, movement situation: walking”, and is determined as condition B. When the number of times the display can be switched to the condition A exceeds a predetermined number, the condition changing unit 106 changes the item of the movement status of the condition A from “still” to “stationary, walking” and the item of the movement status of the condition B “walking”. The setting value is changed from “vehicle” to “vehicle”.

  FIG. 14C shows a pre-change table when the set values of the time zone and movement status items are different for each condition, and FIG. 14D shows a post-change table. The current situation of the mobile terminal 1 is estimated as “8:30, place: station, movement situation: walking”, and is determined as condition B. When the number of times the display can be switched to the condition A exceeds a predetermined number, the condition changing unit 106 changes the setting of the movement status item of the condition A from “still” to “still, walking”. In this example, the condition A and the condition B are set to overlap in all items related to the situation, so the condition changing unit 106 increases the display priority in the condition A by one.

  In this way, in order to change the setting value of the condition item according to the estimation result, if the setting values of the item of each condition other than the item to be changed are completely the same, the item to be changed is presented first. The setting value of the condition item determined by the information determination unit 103 is moved to the setting value of the condition item whose display is switched. If at least one setting value of each condition item is different, the setting value of the condition item whose display is switched is added.

  As described above, the present invention estimates the current status of the mobile terminal and displays the information desired by the user based on the estimation result, and the user does not change the information desired by the user but changes the display by the user. If it does, the change of the display by user operation will be detected, an estimation result or conditions will be updated, and the information which a user desires can be displayed. Therefore, the user does not make a special input as to whether or not the estimation result or condition is appropriate, and the estimation result or condition is not updated. The mobile terminal updates the estimation result or condition only by a normal operation by the user. It is possible to display information suitable for the user.

  Note that there may be provided means for discarding all updated estimation results or conditions and returning them to the initial state.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

  Further, the present invention may be applied to a portable personal computer or a PDA (Personal Digital Assistance) equipped with a wireless communication function instead of the portable terminal in the above embodiment.
