Description

[Technical field]

[0001] The present invention relates to an information providing device, an information providing method, an information providing program, and a recording medium storing the information providing program. [Background technology]

[0002] Conventionally, a navigation device has been proposed that displays a time axis from the current time to the estimated arrival time at the destination, and displays traffic congestion information and information on facilities to be passed through (restrooms, restaurants, gas stations) on the time axis (Patent Document 1). Patent Document 1 also describes that by moving a slider displayed on the time axis, a map of the area around the position that is scheduled to be passed at the time on the time axis indicated by the slider is displayed. Patent Document 2 also proposes a navigation device that displays facility information on a map around the current position. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-51537 A [Patent Document 2] JP 2013-32914 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional navigation devices only tell you how far you will be before you reach a congested area, and whether you will have to pass by facilities such as restrooms, restaurants, and gas stations. In many cases, you have a schedule, such as a concert or a meal, and you head to your destination so that you are on time for the start of the concert or the reservation time for a meal. However, conventional navigation devices only display the time axis from the current time to the expected arrival time, so there is an issue in that you cannot know whether you will make it to your schedule, how late you will be if you do not, or how much time you have if you do make it.

[0005] Therefore, an example of an objective of the present invention is to provide an information providing device, an information providing method, an information providing program, and a storage medium storing the information providing program, which enable a user to grasp at a glance, for example, whether the estimated time of arrival at a destination will be in time for the schedule, how late the user will be, and how much leeway there is. [Means for solving the problem]

[0006] In order to solve the above problem, the invention described in claim 1 includes a schedule acquisition unit that acquires schedule information related to a user's plan, an estimated arrival time acquisition unit that acquires an estimated arrival time at a destination when the schedule information acquired by the schedule acquisition unit has a related destination, and a display control unit that displays on a display unit a time information image including a planned time of the schedule included in the schedule information, When displaying the time information image corresponding to schedule information having a related destination, the estimated time of arrival at the destination is included in the time information image and displayed, and the display mode of the time information image is changed depending on whether the estimated time of arrival is earlier than a specified time before the scheduled time of the schedule or later than the specified time before the scheduled time of the schedule.

[0007] The invention described in claim 4 is an information processing method executed by an information processing device, comprising: a schedule acquisition step of acquiring schedule information relating to a user's plans; an estimated arrival time acquisition step of acquiring an estimated arrival time at the destination when the schedule information acquired in the schedule acquisition step has an associated destination; and a display control step of displaying a time information image including the scheduled time of the schedule included in the schedule information on a display unit, wherein the display control step, when displaying the time information image corresponding to the schedule information having the associated destination, displays the estimated arrival time at the destination included in the time information image, and changes the display mode of the time information image depending on whether the estimated arrival time is earlier than a predetermined time before the scheduled time of the schedule or later than the predetermined time before the scheduled time of the schedule.

[0008] The invention described in claim 5 is characterized in that the information processing method described in claim 4 is executed by a computer. The invention described in claim 6 is characterized in that the information processing program described in claim 5 is stored. [Brief description of the drawings]

[0010] An information processing device according to one embodiment of the present invention will be described below. A schedule acquisition unit acquires schedule information relating to a user's plans. An estimated arrival time acquisition unit acquires an estimated time of arrival at the destination. A current time acquisition unit acquires the current time. A display control unit causes the display unit to display a time axis, and also causes the display unit to display, in association with the time axis, the date and time of the schedule information acquired by the schedule acquisition unit, the current time acquired by the current time acquisition unit, and the estimated arrival time acquired by the estimated arrival time acquisition unit. The display control unit also causes the display format of the date and time of the schedule information to differ depending on whether or not there is a specified relationship between the destination and the location of the schedule information.

[0011] This allows the current time, the expected time of arrival at the destination, and the date and time of schedule information having a predetermined relationship with the destination to be displayed in association with a time axis, allowing a user to grasp at a glance whether he / she will be on time for the schedule information related to the destination, how late he / she will be, and how much time he / she has.

[0012] The display control unit may display the section from the current time to the estimated arrival time on the time axis in a different display format from other sections on the time axis, which makes it easier to understand whether the user will be on time for schedule information related to the destination, how late the user will be, and how much time the user has.

[0013] The display control unit may display the section of the estimated arrival time and the date and time of the schedule information on the time axis in a different display form from the other sections on the time axis, which makes it easier to understand whether the user will be on time for the schedule information related to the destination, how late the user will be, and how much time the user has.

[0014] The display control unit may further include an event information acquisition unit that acquires event information related to the user, and the display control unit may display the event information acquired by the event information acquisition unit in an area on the display unit that is farther from the time axis than the display positions of the date and time, current time, and expected arrival time of the schedule information. This allows the user to know the event information. Moreover, the event information and the schedule information can be easily distinguished.

[0015] The selection unit may receive a user's selection of the event information displayed on the display unit, and the display control unit may display the event information selected by the selection unit as schedule information. This allows the displayed event information to be easily changed to schedule information simply by selecting it with the selection unit.

[0016] The display control unit may also determine whether the time obtained by subtracting the estimated arrival time from the date and time of the schedule information having a predetermined relationship with the destination is equal to or shorter than a first predetermined time, and may change the display form of the section from the current time on the time axis to the estimated arrival time depending on the determination. This allows a user to determine at a glance whether they are likely to make it on time for the schedule information or are likely to be late.

[0017] Also, the route search unit may search for another route if the time obtained by subtracting the expected arrival time from the date and time of the schedule information having a predetermined relationship with the destination is equal to or less than a second predetermined time. This makes it possible to search for a route that will get you to the schedule on time.

[0018] Moreover, in an information processing method according to one embodiment of the present invention, a schedule acquisition step acquires schedule information relating to a user's plans. An estimated arrival time acquisition step acquires an estimated time of arrival at the destination. A current time acquisition step acquires the current time. A display control step causes a time axis to be displayed on the display unit, and also causes the date and time of the schedule information acquired in the schedule acquisition step, the current time acquired in the current time acquisition step, and the estimated arrival time acquired in the estimated arrival time acquisition step to be displayed in association with the time axis. Also, in the display control step, the display format of the date and time of the schedule information is made different depending on whether or not there is a specified relationship between the destination and the location of the schedule information.

[0019] This allows the current time, the expected time of arrival at the destination, and the date and time of schedule information having a predetermined relationship with the destination to be displayed in association with a time axis, allowing a user to grasp at a glance whether he / she will be on time for the schedule information related to the destination, how late he / she will be, and how much time he / she has.

[0020] The above-described information processing method may be implemented as an information processing program executed by a computer. Since the information processing method is implemented by a computer, no dedicated hardware or the like is required, and the information processing method may be implemented by installing the information processing method in a general-purpose information processing device.

[0021] The information processing program may be stored in a computer-readable recording medium, which allows the program to be distributed as a standalone program rather than being incorporated into a device, and allows for easy version upgrades. EXAMPLES

[0022] Next, the above-mentioned information processing device and information processing method will be described below with reference to Fig. 1. Fig. 1 is a block diagram showing an example of a navigation device incorporating an information providing device of the present invention. The navigation device 1 shown in the figure is, for example, a device mounted in a vehicle, and provides guidance on a route to a destination input by a user. In this embodiment, an example in which the navigation device 1 is mounted in a vehicle as described above will be described, but the present invention is not limited to this and may be incorporated in a mobile terminal such as a smartphone or a tablet.

[0023] The navigation device 1 includes a system control unit 2 that controls the entire device, a display device 3 as a display unit, an audio output device 4, an input unit 5, a GPS receiving unit 6, a map database 7, and a communication unit 8, which are connected by a bus 9. The system control unit 2 is configured with a CPU (Central Processing Unit) equipped with memories such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The PU operates according to an information processing program recorded in the ROM.

[0024] The display device 3 is provided, for example, on an instrument panel of a vehicle, and is configured with a liquid crystal display, an organic EL (Electro Luminescence) element, or the like.

[0025] The audio output device 4 includes, for example, a DAC (digital / analog signal converter), an amplifier, a speaker, etc., and performs D / A conversion on the audio data output from the system control unit 2 using the DAC, then amplifies the data using the amplifier and outputs the data as sound waves from the speaker.

[0026] The input unit 5 is composed of, for example, operation buttons and a touch sensor provided on the surface of the display device 3, and the user can input a destination by operating these operation buttons and touch sensors.

[0027] As is well known, the GPS receiver 6 receives radio waves emitted by a plurality of artificial satellites forming a GPS satellite constellation, obtains the current position information of the GPS receiver 6, and outputs this current position information to the system control unit 2. The system control unit 2 then stores the input position information in a RAM or the like in chronological order. Note that the position information includes the current time in addition to the longitude and latitude indicating the position of the vehicle at the time detected by the GPS receiver 6.

[0028] The map database 7 stores map data including image data (including image data of roads, facilities, etc.) for displaying a map on the display device 3 and location information of each location on the map. The system control unit 2 obtains a route to the destination and an estimated arrival time from the GPS receiving unit 6 and the map database 7, and displays them on the display device 3.

[0029] The communication unit 8 is composed of, for example, a Bluetooth (registered trademark) module, and is connected to a smartphone or tablet by wireless communication. The system control unit 2 acquires the user's schedule information stored in the smartphone or tablet, and event information received from a website registered by the user (for example, an invitation to a BBQ sent from an SNS site such as Facebook (registered trademark)), and displays it on the display device 3. In this embodiment, the schedule information and event information displayed on the display device 3 includes the date and time. In some cases, the schedule information and event contents and locations such as meals and concerts may also be included.

[0030] Next, the operation of the navigation device 1 having the above-mentioned configuration will be described with reference to Figures 2 to 4. When a user operates the input unit 5 to input a destination and operates to start guidance, the navigation process shown in Figure 2 starts.

[0031] First, the system control unit 2 functions as a schedule acquisition unit, a current time acquisition unit, and an event information acquisition unit, and acquires location information from the GPS receiving unit 6, as well as the user's schedule information and event information via the communication unit 8 (step S1). Next, the system control unit 2 uses map data stored in the map database 7 to search for a route from the current location information received by the GPS receiving unit 6 to the destination (step S2).

[0032] Thereafter, the system control unit 2 functions as an estimated arrival time acquisition unit, and acquires (calculates) an estimated arrival time at the destination along the route searched in step S2 (step S3). Next, the system control unit 2 acquires important schedule information from the schedule information acquired in step S1 (step S4). Important schedule information is schedule information related to the input destination, and the user inputs the destination in order to execute the important schedule information.

[0033] In step S4, the system control unit 2 extracts schedule information having a location and date and time, and determines the schedule information whose location is within a predetermined range of the destination (predetermined relationship in claims) as important schedule information. If there are multiple schedule information within the predetermined range, the one closest to the destination is determined as important schedule information.

[0034] If the system control unit 2 is unable to acquire important schedule information as a result of performing step S4 (N in step S5), the system control unit 2 immediately proceeds to step S9. On the other hand, if the system control unit 2 is able to acquire important schedule information as a result of performing step S4 (Y in step S5), the system control unit 2 judges whether the time obtained by subtracting the expected arrival time acquired in step S3 from the date and time of the important schedule information is equal to or less than a predetermined time (first predetermined time, second predetermined time in claims) (step S6). If the time is equal to or more than the predetermined time (N in step S6) and the system control unit 2 judges that it will be in time for the important schedule information, the system control unit 2 immediately proceeds to step S9.

[0035] On the other hand, if the time is within the predetermined time (Y in step S6) and the important schedule information cannot be received in time, the system control unit 2 searches again for another route (step S8) if the number of re-searches has not exceeded the predetermined number (Y in step S7), and then returns to step S3. If the time is within the predetermined time (Y in step S6) and the number of re-searches has exceeded the predetermined number (N in step S7), the system control unit 2 proceeds to step S9 without searching again.

[0036] In step S9, the system control unit 2 functions as a display control unit and displays a screen corresponding to the mode selected by the user on the display device 3. That is, when the map mode is selected by operating the input unit 5, the system control unit 2 causes the display device 3 to display a map of the area around the current position and a current position mark indicating the route and the current position on the map. The display in this map mode is similar to the display of a well-known navigation device 1, and therefore a detailed description thereof will be omitted here.

[0037] In response to this, when the private mode is selected by operating the input unit 5, the system control unit 2 causes the display device 3 to display the screens shown in Fig. 3 and Fig. 4. That is, the system control unit 2 causes the display device 3 to display a time axis Z, and also causes the display device 3 to display an important schedule mark M11, a schedule mark M12, a current time mark M2, and an expected arrival time mark M3 in association with the time axis Z.

[0038] Both the important schedule mark M11 and the schedule mark M12 are marks indicating the date and time of the schedule information acquired via the communication unit 8, but the marks are different in order to distinguish between important schedule information acquired in step S4 and schedule information that is not important schedule information. That is, the system control unit 2 changes the display form of the schedule marks M11, M12 depending on whether or not there is a predetermined relationship between the destination and the location of the schedule information (in this embodiment, the location of the schedule information is within a predetermined range of the destination).

[0039] The current time mark M2 is a mark indicating the current time included in the position information acquired from the GPS receiver 6 in step S1 of Fig. 2. In this embodiment, the current time mark M2 is superimposed on the center of the time axis Z, with the right side of the current time mark M2 indicating future information and the left side indicating past information. The estimated arrival time mark M3 is a mark indicating the estimated arrival time acquired in step S3 of Fig. 2.

[0040] Furthermore, the system control unit 2 displays the section on the time axis Z from the current time mark M2 to the estimated arrival time mark M3 in a different display form from other sections on the time axis Z. In this embodiment, as shown in Fig. 3 and Fig. 4, on the time axis Z, the section from the current time mark M2 to the estimated arrival time mark M3 is displayed in a thick line in green or red, and the other sections are displayed in thin white lines, with different thicknesses and colors.

[0041] In addition, the system control unit 2 changes the display form of the section from the current time mark M2 to the estimated arrival time mark M3 on the time axis Z depending on whether the time obtained by subtracting the estimated arrival time from the date and time of the important schedule information is longer than a predetermined time (when the result of the determination in step S6 is N and the process proceeds to step S9) or is equal to or shorter than the predetermined time (when the result of the determination in step S7 is Y and the process proceeds to step S9). In this embodiment, as shown in Fig. 3, if the time is longer than the predetermined time, it can be determined that there is a margin until the important schedule information, and the current time mark M2 to the estimated arrival time mark M3 are displayed in green, for example, on the time axis Z. Also, as shown in Fig. 4, if the time is equal to or shorter than the predetermined time, it can be determined that there is not a margin until the important schedule information, and the current time mark M2 to the estimated arrival time mark M3 are displayed in red, for example, on the time axis Z.

[0042] Furthermore, the system control unit 2 provides the display device 3 with a plurality of regions A1 to A3 arranged in a direction perpendicular to the time axis Z, and causes the display device 3 to display a layer image R1 indicating the boundary between region A1 and region A2, and a layer image R2 indicating the boundary between region A2 and region A3. Note that in the embodiment shown in Figures 3 and 4, layer images R1 and R2 having areas such that regions A1 to A3 are provided three-dimensionally are displayed, but for example, layer images R1 and R2 may be straight lines parallel to the time axis Z, and regions A1 to A3 may be provided two-dimensionally.

[0043] In this embodiment, the time axis Z and marks M11, M12, M2, and M3 are displayed in the bottom area A1. An event window W showing the event information acquired in step S1 is displayed in areas A2 and A3. That is, the system control unit 2 displays the event window W in an area on the display device 3 that is farther away from the time axis Z than the display positions of marks M11, M12, M2, and M3. The event information is categorized, for example, by the website from which it was sent, and displayed in each of areas A2 and A3. Specifically, event information from Facebook is displayed in area A3, and event information from CityDiscovery (registered trademark) is displayed in area A4. The event information also includes a date and time, and the event window W is also displayed at a position associated with the time axis Z.

[0044] The screens shown in Figs. 3 and 4 are merely examples, and screens such as those shown in Figs. 5 and 6 may be displayed. The screens shown in Figs. 5 and 6 will be described below, but in these figures, the same reference numerals are used to designate parts that have the same meaning as those displayed on the screens described in Figs. 3 and 4, and detailed descriptions thereof will be omitted. In the example shown in these figures, the system control unit 2 also displays a time axis Z on the display device 3, and also displays an important schedule mark M11, a schedule mark M12, a current time mark M2, and an expected arrival time mark M3 in association with the time axis Z. The meanings of the time axis Z, the important schedule mark M11, the schedule mark M12, the current time mark M2, and the expected arrival time mark M3 are the same as those in the embodiment described in Figs. 3 and 4, but the display form is different.

[0045] In the examples shown in Figures 3 and 4, the time axis Z is simply represented by a straight line, but in the examples shown in Figures 5 and 6, the time axis Z includes a strip-shaped line L1, and numbers indicating the time are written inside it. Also, in the examples shown in Figures 3 and 4, the schedule marks M11 and M12 are displayed in different forms by changing their shapes, sizes, and colors, but in the examples shown in Figures 5 and 6, both are represented by flags, and the display forms are changed by changing the colors of the flags. Also, the contents and date and time of the schedule marks M11 and M12 are written inside the flags. The current time mark M2 is the same. The estimated arrival time mark M3 is represented by a flag picture that is smaller than the marks M11 and M12.

[0046] 5 and 6, in the section on the time axis Z from the current time mark M2 to the estimated arrival time mark M3, in addition to the above-mentioned band-shaped line L1, a straight line L2 is displayed on it, and the other sections are displayed only as the band-shaped line L1. This makes the display form of the section on the time axis Z from the current time mark M2 to the estimated arrival time mark M3 different from that of the other sections. As shown in FIG. 5, if the time obtained by subtracting the estimated arrival time from the date and time of the important schedule information is longer than a predetermined time, this line L1 is displayed in green, and as shown in FIG. 6, if the time is equal to or shorter than the predetermined time, this line L1 is displayed in red, thereby making the display form of the section from the current time mark M2 to the estimated arrival time mark M3 different depending on whether or not the time is equal to or shorter than the predetermined time.

[0047] 5 and 6, the system control unit 2 provides areas A4 and A5 on the display device 3, with the time axis Z as the boundary. The system control unit 2 displays the marks M11, M12, M2, and M3 in the area A4, and displays the event window W in the area A5.

[0048] Furthermore, the system control unit 2 may move the time axis Z in the axial direction in response to a predetermined operation such as flicking left and right on the screen of the display device 3, and accordingly move each of the marks M11, M12, M2, M3 and the window W in the axial direction. In this case, the system control unit 2 displays a reference line L3. The reference line L3 is represented by, for example, a red straight line perpendicular to the time axis Z, and is fixed without moving even if the time axis Z moves. That is, the display device 3 is configured such that, with the time indicated by the reference line L3 as the reference time, the schedule for, for example, 21 hours after the reference time and the schedule for, for example, 6 hours before the reference time can be confirmed.

[0049] 5 and 6 show an example in which the current time "9:00" is selected as the reference time, and the schedule from "9:00" until 21 hours later and the schedule from "9:00" until 6 hours ago can be confirmed. If the time axis Z is then moved, for example, to the left by a flick operation to select "6:00", three hours ago, as the reference time, the schedule from "6:00" until 21 hours later and the schedule from "6:00" until 6 hours ago can be confirmed.

[0050] It should be noted that this movement of the time axis Z and the display of the reference line L3 can also be applied to the display examples shown in FIGS.

[0051] In the display control process, the system control unit 2 repeatedly acquires the current time and the estimated arrival time, and updates the display.

[0052] In the display control process, when the displayed event window W is touched and event information is selected by the user, the system control unit 2 treats the event information as schedule information and changes it to schedule marks M11 and M12 for display.

[0053] According to the above-mentioned embodiment, the system control unit 2 causes the display device 3 to display the time axis Z, and also causes the display device 3 to display the schedule marks M11, M12, the current time mark M2, and the estimated arrival time mark M3 in association with the time axis Z. The system control unit 2 also causes the schedule marks M11, M12 to be different depending on whether or not there is a specific relationship between the destination and the location of the schedule information. This makes it possible to display the current time mark M2, the estimated arrival time mark M3 at the destination, and the important schedule mark M11 that has a specific relationship with the destination in association with the time axis Z, and makes it possible to grasp at a glance whether the user will be on time for important schedule information related to the destination, how late the user will be, and how much time the user has.

[0054] Furthermore, according to the embodiment described above, the system control unit 2 displays the section from the current time mark M2 to the estimated arrival time mark M3 on the time axis Z in a different display form from the other sections on the time axis Z. This makes it easier to understand whether you will be on time for schedule information related to your destination, how late you will be, and how much time you have.

[0055] Furthermore, according to the embodiment described above, the system control unit 2 displays the event window W in an area on the display device 3 that is farther away from the time axis Z than the display positions of the schedule marks M11, M12, the current time mark M2, and the estimated arrival time mark M3. This allows the user to know the event information. Moreover, it is easy to distinguish between event information and schedule information.

[0056] Furthermore, according to the above-described embodiment, the system control unit 2 may accept a user's selection of event information displayed on the display device 3 and display the selected event information as schedule information. This allows the user to easily change the displayed event information to schedule information simply by making a selection.

[0057] Furthermore, according to the embodiment described above, the system control unit 2 judges whether the time obtained by subtracting the estimated arrival time from the date and time included in the schedule information of a place having a predetermined relationship with the destination is equal to or shorter than a predetermined time, and changes the display form of the section from the current time mark M2 to the estimated arrival time mark M3 on the time axis Z depending on the judgment. This allows the user to judge at a glance whether they are likely to make it on time or late for the schedule information.

[0058] According to the embodiment described above, the system control unit 2 searches for an alternative route if the time obtained by subtracting the expected arrival time from the date and time included in the important schedule information is equal to or shorter than a predetermined time. This makes it possible to search for a route that will get you to the schedule on time.

[0059] In the above embodiment, the section on the time axis Z from the current time mark M2 to the estimated arrival time mark M3 is displayed in a different display format from the other sections on the time axis Z, but this is not limited to the above. Similarly, the system control unit 2 may display the section on the time axis Z from the estimated arrival time mark M3 to the important schedule mark M11 in a different display format from the other sections on the time axis Z.

[0060] In addition, in the above-described embodiment, the event information is displayed in areas A2 and A3 other than area A1, but the present invention is not limited to this. For example, if a photo taken with a mobile terminal of a user can be acquired from the mobile terminal via the communication unit 8, the photo may be displayed in areas A2 and A3. Since the photo also includes the shooting time, the photo can also be displayed in association with the time axis Z.

[0061] In the above embodiment, the thickness and color of the section from the current time mark M2 to the estimated arrival time mark M3 on the time axis Z is different from that of the other sections, but this is not limited to this. In the present invention, it is sufficient that the display form of both sections is different, and for example, only the thickness or color may be different.

[0062] Furthermore, in the above-described embodiment, the time axis Z is displayed along the left-right direction, but this is not limiting, and it may be displayed along the up-down direction.

[0063] Furthermore, in the above-described embodiment, the first and second predetermined times are set to the same time, but this is not limiting, and they may be set to different times.

[0064] The above-mentioned examples are merely representative embodiments of the present invention, and the present invention is not limited to the embodiments. In other words, the present invention can be practiced in various modifications without departing from the gist of the present invention. [Explanation of symbols]
