GUIDING DEVICE, SENSOR UNIT, PORTABLE TERMINAL DEVICE, GUIDING METHOD AND GUIDING PROGRAM
First Claim
1. A position measurement device, comprising:
- a first position detecting unit which detects a present position;
an obtaining unit which obtains a present position detected by a second position detecting unit that detects the present position, by a communication;
a detecting unit which detects a communication condition of the communication; and
an output unit which outputs either the present position detected by the first position detecting unit or the present position detected by the second position detecting unit, based on the communication condition.

Abstract
A guiding device, includes: a first position detecting unit which detects a present position; an obtaining unit which obtains a present position detected by a second position detecting unit, from a sensor unit having the second position detecting unit which detects the present position; a detecting unit which detects a communication condition with the sensor unit; a determining unit which determines whether to preferentially use the present position detected by the first position detecting unit or the present position detected by the second position detecting unit, based on the communication condition; and a controlling unit which displays a guidance based on the present position determined by the determining unit, on a display unit. Therefore, since the present position can be calculated with accuracy, it becomes possible to appropriately perform the guide based on the present position.

10. A portable terminal device, comprising:
-
a first position detecting unit which detects a present position by a GPS position measurement; a displaying unit which displays a navigation guide screen; a communication unit which is fixed to a movable body, and communicates with a sensor unit that includes a second position detecting unit which detects a present position by a GPS position measurement and a sensor which detects a condition of the movable body; and a detecting unit which detects a communication condition with the sensor unit, wherein, when the communication condition detected by the detecting unit is good, the portable terminal device uses position information calculated based on the present position detected by the second position detecting unit and/or the condition of the movable body detected by the sensor which are received from the sensor unit, at the time of displaying the navigation guide screen.

11. A sensor unit being fixed to a movable body, comprising:
-
a position detecting unit which detects a present position by a GPS position measurement; a sensor which detects a condition of the movable body; and a communication unit which communicates with a portable terminal device having a navigation function, wherein the sensor unit calculates position information based on the present position detected by the position detecting unit and/or the condition of the movable body detected by the sensor, and sends the position information to the portable terminal device via the communication unit.
