Definitions

  • the position of the terminal device can be estimated.
  • the display 150 is a display for notifying the user of various information on the screen.
  • the display 150 displays, on the screen, the direction in which the terminal device 20 is to be moved with respect to the antenna 130 of the display unit 10 as the method of moving the terminal device 20, based on the control by the instruction unit 103. Instruct the user.
  • the instruction unit 103 instructs how to move the terminal device 20 so that the obtained voltage waveform approaches the ideal waveform shown in FIG. 3 until the display 10 and the terminal device 20 become communicable. However, since it is initially unclear how the terminal device 20 should be moved so that the voltage waveform changes so as to approach the ideal waveform, an appropriately defined way of movement is instructed. An example of position estimation and indication will be described below with a simple concrete example.
  • the position estimation unit 102 moves the antenna 220 of the terminal device 20 exists to the right of the antenna 130 of the display 10 as seen from the user, and the instruction unit 103 instructs to move the terminal device 20 in the opposite direction, that is, in the left direction.
  • the display device 10 includes a processor 1001, a memory 1002, an interface 1003, and a secondary storage device 1004, which are connected to each other via a bus 1000.
  • the memory 1002 is, for example, a main memory configured by RAM (Random Access Memory).
  • the memory 1002 stores an operating program read by the processor 1001 from the secondary storage device 1004 . Also, the memory 1002 functions as a working memory when the processor 1001 executes the operating program.
  • the control unit 100 determines whether or not the display device 10 and the terminal device 20 can communicate with each other (step S104). For example, the control unit 100 controls the communication control unit 104 to transmit some signal to the outside, and determines that the display 10 and the terminal device 20 can communicate with each other when a response to the signal is received.
  • step S205: Yes the control unit 100 finishes creating the feature quantity map.
  • step S205: No the control section 100 repeats the operation from step S201.
  • the control unit 100 determines whether or not the display device 10 and the terminal device 20 can communicate with each other (step S303). When the display 10 and the terminal device 20 can communicate with each other (step S303: Yes), the control unit 100 terminates the position estimation operation.
  • the above program may be stored in a storage device owned by another server on the Internet, and the above program may be downloaded from that server.
