Means for Solving the Problems

[0006] A navigation device according to an embodiment of the present disclosure includes a control unit, an output unit that displays the processing result of the control unit, and is provided with The control unit extracts a plurality of destination candidates from the destination conditions input by the user, randomly selects one destination candidate as the destination from the plurality of destination candidates, generates a roulette in which the plurality of destination candidates are arranged as cells, creates a description for displaying how the destination is selected using the roulette. [Effects of the Invention]

[0007] According to one embodiment of this disclosure, the technology related to destination selection in a navigation device is improved. [Brief explanation of the drawing]

[0008] [Figure 1] This block diagram shows a schematic configuration of a navigation device according to one embodiment of the present disclosure. [Figure 2] This is a flowchart showing the operation of the navigation system. [Modes for carrying out the invention]

[0009] The embodiments of this disclosure will be described below.

[0010] Referring to Figure 1, an overview of the navigation device 1 according to the embodiment of this disclosure will be described. The navigation device 1 comprises a control unit 10, a storage unit 11, an input unit 12, and an output unit 13. The navigation device 1 may be an information processing device mounted on a vehicle. The navigation device 1 may be configured to be detachable from the vehicle.

[0011] First, an overview of this embodiment will be described, and details will be described later. Navigation device 1 receives input of destination conditions from the user and extracts multiple destination candidates that match those conditions. Then, navigation device 1 randomly selects one destination candidate from the multiple destination candidates as the destination, generates a roulette wheel with the multiple destination candidates arranged as squares, and creates a depiction showing how the destination is selected using the roulette wheel.

[0012] Thus, according to this embodiment, the destination can be determined randomly simply by the user setting the destination conditions. Therefore, for example, it is easy to set a destination that takes into account the user's needs. It also becomes possible to set a destination that the user is unaware of. Consequently, the technology related to destination selection in navigation devices is improved.

[0013] Next, we will describe in detail each component of the navigation device 1.

[0014] The control unit 10 includes one or more processors, one or more programmable circuits, one or more dedicated circuits, or a combination thereof. The processor is a general-purpose processor such as a CPU (Central Processing Unit) or GPU (Graphics Processing Unit), or a dedicated processor specialized for a specific process, but is not limited to these. The programmable circuit is an FPGA (Field-Programmable Gate Array), but is not limited to this. The dedicated circuit is an ASIC (Application Specific Integrated Circuit), but is not limited to this. The control unit 10 executes various processes related to the operation of the navigation device 1 and controls each part of the navigation device 1.

[0015] The storage unit 11 includes one or more memories. The memories are, for example, semiconductor memories, magnetic memories, or optical memories, but are not limited to these. Each memory included in the storage unit 11 may function as, for example, a main memory, an auxiliary memory, or a cache memory. The storage unit 11 stores any information used for the operation of the navigation device 1. For example, the storage unit 11 may store system programs, application programs, and embedded software.

[0016] The input unit 12 includes one or more input interfaces. The input interface is, for example, a physical key, a capacitive key, a pointing device, a touch screen provided integrally with the display, or a microphone that accepts voice input. The input unit 12 accepts an operation for inputting information used for the operation of the navigation device 1.

[0017] The output unit 13 includes one or more output interfaces. The output interface is, for example, an external or built-in display that outputs information as an image / video or a connection interface to an external output device. The display is, for example, an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display. The output unit 13 outputs information obtained by the operation of the navigation device 1.

[0018] Referring to FIG. 2, the operation of the navigation device 1 according to the present embodiment will be described.

[0019] S1: The control unit 10 of the navigation device 1 accepts an input of destination conditions from the user via the input unit 12. The destination conditions may be any conditions. For example, they may be genre, prefecture or municipality, one-way distance, one-way time, highway toll upper limit, presence or absence of fuel replenishment, or store evaluation lower limit, etc.

[0020] S2: The control unit 10 extracts a predetermined number of destination candidates based on the destination conditions input in S1. The predetermined number may be any number of 2 or more. The destination candidates may be extracted, for example, from the locations stored in the storage unit 11.

[0021] S3: The control unit 10 outputs the destination candidates extracted in S2 to the output unit 13 and asks the user to confirm whether they agree to select a destination from the extracted destination candidates. If the user agrees to the destination candidates extracted in S2 (S3: Yes), the process proceeds to S4. If the user does not agree to the destination candidates extracted in S2 (S3: No), the process returns to S1.

[0022] S4: The control unit 10 selects a destination from the destination candidates extracted in S2. The selection method may be, for example, random.

[0023] S5: The control unit 10 generates a roulette wheel with the destination candidates extracted in S2 set as its squares. After generating the roulette wheel, the control unit 10 creates a display showing how a destination is selected using the roulette wheel and outputs it to the output unit 13.

[0024] S6: The control unit 10 generates a screen to ask the user if it is OK to start route guidance to the destination determined in S4, and outputs it to the output unit 13. If the user gives input that it is OK to start route guidance to the destination determined in S4 (S6: Yes), the process proceeds to S7. If the user gives input requesting that route guidance to the destination determined in S4 not be started (S6: No), the process returns to S1.

[0025] S7: The control unit 10 starts route guidance to the destination determined in S4, and the process ends.

[0026] As described above, the navigation device 1 according to this embodiment receives input of destination conditions from the user and extracts multiple destination candidates that match those conditions. The navigation device 1 then randomly selects one destination candidate from the multiple destination candidates as the destination, generates a roulette wheel with the multiple destination candidates arranged as squares, and creates a display showing how the destination is selected using the roulette wheel.

[0027] With this configuration, the destination can be determined randomly simply by the user setting the destination conditions. Therefore, it becomes easy to set destinations that reflect the user's needs, for example. It also becomes possible to set destinations unknown to the user. Thus, the technology related to destination selection in navigation devices is improved.

[0028] While this disclosure has been described based on the drawings and embodiments, it should be noted that those skilled in the art may make various modifications and alterations based on this disclosure. Therefore, it should be noted that these modifications and alterations are within the scope of this disclosure. For example, the functions, etc., included in each component or step can be rearranged in a logically consistent manner, and multiple components or steps can be combined into one or divided into two.

[0029] For example, instead of accepting destination conditions from the user, the control unit 10 of the navigation device 1 may accept destination candidates from the user. In this case, the control unit 10 may use the input destination candidates instead of the extracted destination candidates when performing the processing from S4 onwards. [Explanation of Symbols]
