First Claim
1. A portable information terminal comprising:
- a position detecting section to detect a position of the portable information terminal;
a selecting section to select a guidance target object for which voice guidance is to be provided, and to detect a guidance target direction that is a first direction in which the guidance target object exists with respect to a reference direction, based at least in part on a second direction in which the guidance target object exists with respect to the position of the portable information terminal;
a voice synthesis section to generate a synthetic voice so that a guidance voice for the guidance target object selected by the selecting section is heard from the guidance target direction; and
a voice output section to output the synthetic voice generated by the voice synthesis section.

Abstract
A portable information terminal includes: a position detecting section that detects a position of the portable information terminal; a selecting section that selects a guidance target object for which voice guidance is to be provided, and detects a guidance target direction that is a direction in which the guidance target object exists with respect to a reference direction, on the basis of a direction in which the guidance target object exists with respect to the position of the portable information terminal; a voice synthesis section that generates a synthetic voice so that a guidance voice for the guidance target object selected by the selecting section is heard from the guidance target direction; and a voice output section that outputs the synthetic voice generated by the voice synthesis section.

15. A control method for controlling a portable information terminal, the control method comprising:
-
detecting a position of the portable information terminal; selecting a guidance target object for which voice guidance is to be provided, and detecting a guidance target direction that is a first direction in which the guidance target object exists with respect to a reference direction, based at least in part on a second direction in which the guidance target object exists with respect to the position of the portable information terminal; generating a synthetic voice so that a guidance voice for the selected guidance target object is heard from the guidance target direction; and outputting the synthetic voice.

16. An information providing device that provides information to a portable information terminal, the information providing device comprising:
-
a receiving section to receive a position of the portable information terminal transmitted from the portable information terminal; a selecting section to select a guidance target object for which voice guidance is to be provided, and to detect a guidance target direction that is a first direction in which the guidance target object exists with respect to a reference direction, based at least in part on a second direction in which the guidance target object exists with respect to the position of the portable information terminal; a voice synthesis section to generate a synthetic voice so that a guidance voice for the guidance target object selected by the selecting section is heard from the guidance target direction; and a transmitting section to transmit the synthetic voice generated by the voice synthesis section, which is to be outputted by the portable information terminal, to the portable information terminal.

17. A control method for an information providing device that provides information to a portable information terminal, the control method comprising:
-
receiving a position of the portable information terminal transmitted from the portable information terminal; selecting a guidance target object for which voice guidance is to be provided, and detecting a guidance target direction that is a first direction in which the guidance target object exists with respect to a reference direction, based at least in part on a second direction in which the guidance target object exists with respect to the position of the portable information terminal; generating a synthetic voice so that a guidance voice for the guidance target object is heard from the guidance target direction; and transmitting the synthetic voice, which is to be outputted by the portable information terminal, to the portable information terminal.

18. A portable information terminal to which information is provided from an information providing device, the portable information terminal comprising:
-
a position detecting section to detect a position of the portable information terminal; a transmitting section to transmit the position of the portable information terminal detected by the position detecting section to the information providing device; a receiving section to receive from the information providing device a synthetic voice generated so that a guidance voice for a guidance target object for which guidance is to be provided is heard from a first direction in which the guidance target object exists with respect to a reference direction and which is detected based at least in part on the position of the portable information terminal transmitted by the transmitting section; and a voice output section to output the synthetic voice received by the receiving section.

-
19. A control method for a portable information terminal to which information is provided from an information providing device, the control method comprising:
-
detecting a position of the portable information terminal; transmitting the position of the portable information terminal to the information providing device; receiving from the information providing device a synthetic voice generated so that a guidance voice for a guidance target object for which guidance is to be provided is heard from a first direction in which the guidance target object exists with respect to a reference direction and which is detected based at least in part on the position of the portable information terminal; and
outputting the synthetic voice.
