Abstract

PROBLEM TO BE SOLVED: To raise efficacy of access to life-log data by making it possible to variably set a display priority to the life-log data according to conditions when a user accesses the life-log data.SOLUTION: A life-log display controlling device periodically acquires information showing a displayed time zone and current time while displaying life-log data, and stores the information as a scroll operation history in a time axis operation information temporarily storing unit 31. When a redrawing order is input in a user terminal in this state, the controlling device uses the scroll operation history information stored in the time axis operation information temporarily storing unit 31 to recalculate a display index so that a value of life-log data displayed on a display screen by user operation for a long time and a value of other life-log data relating to the life-log data become big. Then, the controlling device reselects life-log data to be displayed in accordance with the recalculated display index, and displays the reselected life-log data.

Description

  The present invention relates to a life log display control device, method, and program for controlling display of life log data obtained from a user's daily life.

  In recent years, various information obtained from a user's daily life is constantly collected as life log data using a position measurement function and various sensors mounted on a portable terminal such as a mobile phone. It has been proposed to use various information providing services such as advertisements and news, and user health management services.

  By the way, when providing life log data to a service provider, it is necessary for the user to check in advance whether or not to provide the service provider with data that the user does not want to be known to others. It is necessary to visualize life log data. In visualizing life log data, since many life log data are associated with “time”, it is generally visualized on a time axis. For example, Non-Patent Document 1 describes a technique for displaying data such as operation history on a personal computer and image data captured by the personal computer on a time axis.

J. Rekimoto, "Time-Machine Computing: A Time-centric Approach for the Information Environment", In Proc. Of UIST'99, pp.45-54, 1999.

  However, the conventional technology for visualizing life log data has the following problems to be solved. In other words, when the daily life situation of a person is always electronically recorded, a large amount of diverse information is collected as life log data, so if the display time granularity is coarse, all life log data is displayed. You will not be able to. For this reason, there is a need to display life log data important for the user. Furthermore, the life log data important for the user is highly likely to change depending on the situation of the user at that time.

  For example, when looking back on life log data for a certain year, when viewing life log data related to work, it is desirable to preferentially display important events related to work and life log data related to business trips. On the other hand, when viewing life log data related to private life, it is preferable to preferentially display life log data related to travels and the like performed privately.

  In other words, not only “important information” is uniformly extracted and displayed based on the characteristics of the accumulated life log data, but also the conditions when the user wants to view the life log data, for example, the browsing target It is desired that the priority for the life log data can be appropriately switched and displayed according to the time zone and the user's situation at the time of browsing.

  This invention has been made paying attention to the above circumstances, and its purpose is to enable variable setting of display priority for life log data according to conditions when the user browses life log data, Accordingly, it is an object of the present invention to provide a life log display control device, method, and program in which life log data browsing efficiency is improved.

  In order to achieve the above object, according to a first aspect of the present invention, information relating to a user's life situation is collected a plurality of times over a first period from a terminal carried by the user, and each of the collected information is generated. It is stored in a storage medium as life log data in association with information representing the time. And, for each of the life log data included in the unit time zone set shorter than the first period among the plurality of stored life log data, the time that the life log data occupies in the unit time zone Based on the ratio and the ratio of the time that the life log data related to the life log data occupies in the first period, a display index representing the display priority of the life log data is calculated, and this calculated In accordance with the display index, life log data is selected from a plurality of life log data included in the unit time zone by the upper limit number set in the descending order of the display index, and the selected life log data is time-scaled. Are displayed on the display medium in association with each other.

  Specifically, when calculating the display index, the larger the proportion of the time that the life log data occupies in the unit time zone, and the time that the life log data related to the life log data occupies in the first period. A display index having such a value that the priority is higher as the ratio is smaller is calculated.

  Therefore, according to the first aspect of the present invention, for each unit time zone on the time axis, a display index is calculated for each of a plurality of life log data included in the unit time zone, and the display index is in descending order. The upper limit number of life log data designated in advance is selected and preferentially displayed. Here, the display index increases as the proportion of the time in the unit time zone of the life log data increases, and as the proportion of the time in which the life log data related to the life log data occupies the first period decreases. growing. Therefore, the life log data can be preferentially displayed in consideration of the data length (time length) of the life log data and the small amount of related life log data (that is, the scarcity of data). As a result, the user can efficiently browse the life log data having a long data length and high scarcity as highly important data in a short time.

  According to a second aspect of the present invention, when a scroll operation in the time axis direction is performed by a user during a display operation of life log data, a function for scrolling the life log data is provided. For each of the life log data, the display time on the display screen is measured. Based on the measured display time, the life log data and the life log data are It changes the display index of related life log data.

  In general, when a user browses life log data while performing a scroll operation, the scroll speed becomes slower and the display time becomes longer in a time section including life log data important for the user. Therefore, if the display time of the life log data during scroll display is measured as described above and the display index is changed so that the display priority becomes higher as the measured display time length is longer, the priority for the life log data is increased. The degree can be set more accurately in consideration of the state of the user's browsing operation.

  According to a third aspect of the present invention, when a life log data or time selection operation is performed by the user during the life log data display operation, the selected position is detected as a user's attention site on the display screen. Then, the display time of the life log data at the detected attention site is measured for each of the life log data being scroll-displayed, and the display priority becomes higher as the time length is longer based on the measured display time. The display index of the life log data and the life log data related to the life log data is changed so as to be higher.

  In general, when searching for a life log that the user wants to browse while scrolling the time axis, instead of searching for the life log that the user wants to browse while viewing the entire display screen evenly, a specific part of the display screen, for example, near the display position of the mouse pointer I often search while watching. For this reason, when a plurality of life log data is displayed on the display screen at the same time, the life log data that is displayed on the part of the display screen that the user is gazing at or in the vicinity thereof has a longer time log data. It can be regarded as important life log data.

  Therefore, as described above, the attention site of the user on the display screen is detected, the display time of the life log data in this attention site is measured, and the longer the time length is based on the measured display time, Change the display index so that the display priority is higher. In this way, when multiple life log data are displayed on the display screen at the same time, the user on the display screen pays attention without giving high priority to all of the life log data. It is possible to give high priority to life log data displayed for a long time at a certain site. Therefore, the priority for the life log data can be set more accurately in consideration of the user's line of sight.

  In other words, according to the present invention, it becomes possible to variably set the display priority for the life log data according to the conditions when the user views the life log data, thereby improving the life log data browsing efficiency. A life log display control device, method, and program can be provided.

The flowchart which shows the procedure and processing content of the life log display control by the life log management server shown in FIG. The figure which shows an example of the life log data memorize | stored in the life log database of the life log management server shown in FIG. The figure which shows the example of a display of life log data.

Embodiments according to the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a life log management server having a life log data display control function according to an embodiment of the present invention.
The life log management server 1 includes an input / output interface unit 10, a control unit 20, and a storage unit 30. The input / output interface unit 10 receives operation data and transmits display data via a communication network with a user terminal as an input / output device under the control of the control unit 20. As the user terminal, for example, a fixed information terminal such as a personal computer, or a portable terminal such as a mobile phone, a smart phone, or a PDA (Personal Digital Assistant) is used.

  The storage unit 30 uses a randomly accessible non-volatile memory using an HDD (Hard Disc Drive) or an SSD (Solid State Drive). As a storage unit necessary to realize the present invention, a time axis operation is performed. An information temporary storage unit 31, a life log / display index temporary storage unit 32, and a life log database 33 are provided.

  The life log database 33 stores user life log data collected from a user's portable terminal or sensor group in a past fixed period. FIG. 3 shows an example of life log data stored in the life log database 33. As shown in FIG. 3, each life log data includes information indicating the start time, the end time, and the contents of the life log. It consists of information associated with identification information (ID).

The time axis operation information temporary storage unit 31 is used to store information indicating the time zone being displayed and the current time received from the user terminal as information indicating the operation history of the time axis.
The life log / display index temporary storage unit 32 is used to temporarily store a display index calculated by the control unit 20 described later in a state associated with the identification ID of the life log data.

  The control unit 20 includes a central processing unit (CPU) as a core. As a control function necessary for carrying out the present invention, a time axis operation information acquisition unit 21 and life log / time designation information are provided. An acquisition unit 22, a display index calculation unit 23, a redrawing command acquisition unit 24, a life log drawing processing unit 25, and a life log display control unit 26 are provided. All of these control functions are realized by causing the CPU to execute an application program stored in a program memory (not shown) in the storage unit 30.

  The time axis operation information acquisition unit 21 displays the information indicating the time zone being displayed at regular time intervals together with the current time information during the display operation of the life log data including the scroll display operation in the time axis direction. The time axis operation information temporary storage unit 31 stores the received information indicating the displayed time zone and the current time as a time axis operation history.

  The life log / time designation information acquisition unit 22 receives operation information from the input / output interface unit 10 when the user terminal performs a click operation or the like for selecting and specifying the life log data or time during the display of the life log data. The process to receive via is performed.

  The display index calculation unit 23 stores information on unit time zones specified in advance for each life log data stored in the life log database 33 and the time axis operation temporarily stored in the time axis operation information temporary storage unit 31. This is an index for determining life log data to be preferentially displayed on the display screen based on the information and life log data received by the life log / time designation information acquisition unit 22 or time selection operation information. Calculate the “display index”. Then, a process of temporarily storing the calculated display index in the life log / display index temporary storage unit 32 in association with the ID of the corresponding life log data is performed.

  When the user terminal inputs a re-determination / re-rendering command for life log data to be displayed by the user while the life log data is being displayed on the user terminal, the re-rendering command acquisition unit 24 sends the command information to the input / output interface unit 10. The process to receive via is performed.

  In accordance with the display index temporarily stored in the life log / display index temporary storage unit 32, the life log drawing processing unit 25 displays the display index from the life log data included in the unit time period for each unit time period. Life log data corresponding to the upper limit number specified in advance is selected in descending order. Then, the selected life log data is read from the life log database 33, and processing for generating display data for displaying the read life log data in association with the time axis is performed.

  The life log display control unit 26 performs processing for transmitting the display data generated by the life log drawing processing unit 25 from the input / output interface unit 10 to the user terminal and displaying the display data on the display.

Next, the life log data display control operation by the apparatus configured as described above will be described. FIG. 2 is a flowchart showing the control procedure and contents.
(1) Initial display of life log data When a life log browsing request is received from a user terminal, the control unit 20 generates life log initial display data under the control of the life log drawing processing unit 25 as follows.
That is, first, in step S1, life log data whose time is included in the time zone is read from the life log database 33 for each unit time zone specified in advance. Next, in step S2, the display index calculation unit 23 is activated to calculate a display index for each of the read life log data. This display index is calculated by the following equation (1), for example.

However,
pi; display index of life log data with ID i; i: time length that life log data with ID i occupies in the corresponding unit time zone l; time length of specified unit time zone n; stored in the life log database 33 The start time of the life log data with the oldest start date / time is to and the end time of the life log data with the newest end date / time is tn.
Value calculated by n = (tn-to) / l ni: Life log data related to the corresponding life log data, for example, life log data having the same content as the “life log content” of the corresponding life log data The number of existing unit time zones. The life log data extending over a plurality of unit time zones is calculated by calculating the above pi for each unit time zone and then taking the average.

  That is, the display coefficient at the time of initial display is the same as the “life log content” of the life log data as the proportion of the life log data included in the unit time period in the specified unit time period is longer. The smaller the number of life log data having contents in other time zones, the larger the value.

  The calculation of the display index described above is performed separately for each unit time zone for all life log data stored in the life log database 33. When the calculation of the display index is completed for all the life log data, in step S3, the display index calculation unit 23 associates the display index obtained by the calculation with the ID of the corresponding life log data. Stored in the display index temporary storage unit 32.

  Subsequently, the control unit 20 starts the life log drawing processing unit 25 and the life log display control unit 26 in step S4, and is temporarily stored in the life log / display index temporary storage unit 32 by the life log drawing processing unit 25. In accordance with the display index, life log data corresponding to the upper limit number specified in advance is selected from the life log data included in the unit time period in descending order of the display index. Then, display data for displaying the selected life log data in association with the time axis is generated. Then, the life log display control unit 26 transmits the generated display data from the input / output interface unit 10 to the user terminal and displays it on the display.

  Thus, in the user terminal, the life log data occupies a unit time zone (data size) and life log data having the same content as the “life log content” of the life log data is stored in other time zones. Life log data in which display priority is set in consideration of the number existing in (data scarcity) is displayed in association with the time axis. FIG. 4 shows an example of life log data displayed in this way.

(2) Redisplay of life log data according to user's operation (2-1) When user performs scroll operation During the display of the life log data, the control unit 20 performs the life log by the user in step S5 and step S6, respectively. Data or time selection operation and redraw command input operation are monitored. When a predetermined time has elapsed without any of these operations being performed, the process proceeds from step S7 to step S8, and the current “time information” is transferred from the user terminal under the control of the time axis operation information acquisition unit 21. And “information indicating the time zone being displayed” are temporarily stored in the time axis operation information temporary storage unit 31.

  Further, the control unit 20 monitors whether or not the user has performed a time axis operation, that is, a scroll operation in step S9. If the scroll operation has not been performed, the control unit 20 returns to step S5 and performs the processes in steps S5 to S9. repeat. In contrast, it is assumed that the user performs a scroll operation on the displayed life log data. Then, the control unit 20 proceeds from step S9 to step S10, and updates the content of the display data in accordance with the scroll operation under the control of the life log drawing processing unit 25. In step S11, the updated display data is transmitted from the input / output interface unit 10 to the user terminal under the control of the life log display control unit 26, and the process returns to step S5. Thus, the life log data displayed on the user terminal is scrolled in the time axis direction according to the user's scroll operation.

  The processes from step S5 to step S11 are repeated until life log data or time selection operation or redraw command input operation is detected. Therefore, if a scroll operation is performed in the time axis direction at the user terminal, the display data is updated in accordance with the scroll operation, and the updated “information indicating the display time zone” is displayed at regular intervals. This is collected from the terminal, and is stored in the time axis operation information temporary storage unit 31 as a scroll operation history.

Now, assume that the user performs an operation for inputting a redrawing command in this state. Then, the control unit 20 receives this redrawing command by the redrawing command acquisition unit 24, and proceeds from step S6 to step S13. Then, under the control of the display index calculation unit 23, the life log data stored in the life log database 33 is read, and the display index is recalculated for each read life log data. This recalculation of the display index is performed by the following equation (2), for example.

However,
pi; display index of life log data with ID i; i: time length that life log data with ID i occupies in the corresponding unit time zone l; time length of specified unit time zone n; stored in the life log database 33 The start time of the life log data with the oldest start date / time is to and the end time of the life log data with the newest end date / time is tn.
Value calculated by n = (tn-to) / l ni: Life log data related to the corresponding life log data, for example, life log data having the same content as the “life log content” of the corresponding life log data Number of unit time zones existing m: Number of life log data having the same contents as the “life log contents” of the corresponding life log data among the life log data stored in the life log database 33 c j; In the life log data having the same contents as the “life log contents” of the life log data, accumulation of operation history information is started in the time axis operation information temporary storage unit 31 for the j (1 to m) th life log. The time length displayed after that.

  That is, the display index pi after the scroll operation uses the scroll operation history information accumulated in the time axis operation information temporary storage unit 31 and the life log data displayed on the screen by the user operation for a long time, The other life log data related to the life log data is recalculated so that the value becomes larger.

  The recalculation of the display index according to the scroll operation described above is performed separately for each unit time zone for all the life log data stored in the life log database 33. When the calculation of the display index for all the life log data is completed, the display index stored in the life log / display index temporary storage unit 32 in step S14 is recalculated by the above equation (2). Update to index.

Subsequently, the control unit 20 activates the life log drawing processing unit 25 and the life log display control unit 26 in step S15, and the life log drawing processing unit 25 stores the re-stored data in the life log / display index temporary storage unit 32. According to the calculated display index, life log data for the upper limit number specified in advance is selected again from the life log data included in the unit time period in the order of increasing display index for each unit time period. Then, display data for displaying the selected life log data in association with the time axis is generated. Subsequently, the life log display control unit 26 transmits the generated display data from the input / output interface unit 10 to the user terminal, and displays it on the display. Finally, in step S16, the time axis operation information stored in the time axis operation information temporary storage unit 31 is deleted.
Thus, the life log data displayed on the user terminal is reselected and redisplayed according to the priority order reflecting the user's scroll operation.

(2-2) When the user designates life log data or time being displayed The user selects and designates desired life log data or time by clicking or the like while the life log data is being displayed. Then, the control unit 20 proceeds from step S5 to step S12, and receives the life log data or the time operation information transmitted from the user terminal under the control of the life log / time designation information acquisition unit 23. Receive via.

Next, in step S13, the control unit 20 reads the life log data stored in the life log database 33 under the control of the display index calculation unit 23, and calculates the display index for each read life log data. Perform the process again. This recalculation of the display index is performed by, for example, the following formula (3).

ｗ；表示画面上の横幅
とする。 However,
pi; display index of life log data with ID i; i: time length that life log data with ID i occupies in the corresponding unit time zone l; time length of specified unit time zone n; stored in the life log database 33 The start time of the life log data with the oldest start date / time is to and the end time of the life log data with the newest end date / time is tn.
Value calculated by n = (tn-to) / l ni: Life log data related to the corresponding life log data, for example, life log data having the same content as the “life log content” of the corresponding life log data Number of unit time zones existing m: Number of life log data having the same contents as the “life log contents” of the corresponding life log data among life log data stored in the life log database 33 cjk; In the life log having the same content as the “life log content” of the life log, the j (1 to m) th life log data is located at the position k (0 ≦ k ≦ w) in the time axis direction on the display screen. Displayed time length dk; The time selected by the user or the position on the display screen of the life log as e (0 <e <w)

w: The width on the display screen.

  That is, the display index pi in the life log data or time selection designation operation is the life log data and the life log that are displayed at a longer position at a position closer to the position where the user has performed the selection operation on the display screen. Recalculation is performed so that the display priority of other life log data related to the data becomes higher.

  The recalculation of the display index according to the life log data or time selection / designation operation described above is performed for each unit time zone for all the life log data stored in the life log database 33. When the calculation of the display index for all the life log data is completed, the display index stored in the life log / display index temporary storage unit 32 is updated to the display index recalculated by the above equation (3). To do.

Subsequently, the control unit 20 activates the life log drawing processing unit 25 and the life log display control unit 26 in step S15, and the life log drawing processing unit 25 stores the re-stored data in the life log / display index temporary storage unit 32. According to the calculated display index, life log data for the upper limit number specified in advance is selected again from the life log data included in the unit time period in the order of increasing display index for each unit time period. Then, display data for displaying the selected life log data in association with the time axis is generated. Subsequently, the life log display control unit 26 transmits the generated display data from the input / output interface unit 10 to the user terminal, and displays it on the display. Finally, in step S16, the time axis operation information stored in the time axis operation information temporary storage unit 31 is deleted.
Thus, the life log data displayed on the user terminal is re-selected and re-displayed according to the priority order reflecting the life log data or time selection designation operation by the user.

As described above in detail, in this embodiment, when life log data is displayed on the user terminal, the following display control is performed.
(1) First, in the initial state before the user operation is performed, for each life log data stored in the life log database 33, a unit designated according to the equation (1) for each unit time zone designated in advance. The longer the proportion of the life log data included in the unit time zone in the time zone, the more the number of life log data having the same content as the “life log content” of the life log data exists in other time zones. The display index is calculated so that the smaller the value, the larger the value. Then, according to the calculated display index, life log data corresponding to the upper limit number specified in advance in order of display index is selected from the life log data included in the unit time period for each unit time period. The selected life log data is displayed in association with the time axis.

  Therefore, for each unit time zone, out of a plurality of life log data included in this unit time zone, the length of time that the life log data occupies the unit time zone and the related life log data are small (that is, the data is scarce) Life log data is selected and displayed with priority. For this reason, the user can browse the life log data having a long time length that occupies the unit time zone for each unit time zone and having high rarity as highly important data and efficiently browsing in a short time. .

  (2) While displaying the life log data, information indicating the displayed time zone and the current time is periodically acquired and stored in the time axis operation information temporary storage unit 31 as a scroll operation history. . In this state, when a redrawing command is input at the user terminal, the scroll operation history information stored in the time axis operation information temporary storage unit 31 is used for each life log data according to the above equation (2). The display index is recalculated so that the life log data displayed on the display screen by the user operation has a longer value and the other life log data related to the life log data has a larger value. Then, in accordance with the recalculated display index, life log data to be displayed is selected again and displayed.

  Accordingly, in consideration of the display time of the life log data during scroll display, the display index is changed so that the display priority becomes higher as the display time length is longer. For this reason, the priority with respect to life log data can be set more correctly in consideration of the status of the user's scroll operation.

  (3) When life log data or time selection is specified by the user while the above life log data is displayed, the user selects each life log data on the display screen according to the above equation (3). The display index is calculated so that the display priority of the life log data that has been displayed at that position and the other life log data related to the life log data is higher in the place closer to the operated position. cure. Then, in accordance with the recalculated display index, life log data to be displayed is selected again and displayed.

  Therefore, when multiple life log data are displayed on the display screen at the same time, among these life log data, the life log data that has been displayed for a long time on the part of the display screen that the user is watching is displayed. It becomes possible to give high priority to it. For this reason, the priority with respect to life log data can be set still more correctly in consideration of a user's eyes | visual_axis with respect to a display screen.

The present invention is not limited to the above embodiment. For example, in the embodiment, the case where the life log display control function according to the present invention is provided in the life log management server has been described as an example. However, the present invention is not limited to this, and the life log display control function according to the present invention may be provided in the user terminal.
In addition, the type and configuration of the life log display control device, the procedure and processing contents of the life log display control processing, and the like can be variously modified and implemented without departing from the gist of the present invention.

  In short, the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment.
