Abstract: A sleepiness calculation device is provided. In a smartphone, I/F obtains heart rate of the subject measured by a heartbeat sensor and measurement time, determines active state of a subject in the state discriminant section, and send it to a server. Next, in the server, a correction section obtains sleepiness baseline heart rate from a sleepiness baseline heart rate table storing sleepiness baseline heart rate of the subject for each active state according to an active state sent from the smartphone. Next, the sleepiness baseline heart rate obtained by the correction section is corrected based on fatigue degree, sleep time, and state of meals. Thereafter, the corrected sleepiness baseline heart rate (correction sleepiness baseline heart rate) is sent to the smartphone. Sleepiness level calculation section of the smartphone calculates sleepiness level of the subject based on correction sleepiness baseline heart rate and heart rate obtained by I/F.

The combiner 5 reflects the light of the guide image Im displayed by the portable terminal 100 to let an observer visually recognize the image as a virtual image Iv. The base unit 3 is connected to the portable terminal holding unit 7 and the combiner 5.

Abstract: A map display apparatus includes a display that displays a map viewed at a given angle for bird's eye view with respect to the ground; a touch panel that is disposed on the display; a determining unit that determines strength of touch of an object on the touch panel; a display controller that controls a display format of the map displayed on the display, based on a result of determination by the determining unit, where the display controller scrolls the map when the strength of touch is at most a given strength, and changes the angle for bird's eye view when the strength of touch exceeds the given strength.

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.

Abstract: A navigation apparatus includes an obtaining unit, a storage unit, an extracting unit, a navigation unit and a determination unit. The obtaining unit obtains an image captured by an imaging unit. The storage unit stores landmark information relating to facilities. The extracting unit extracts at least one landmark corresponding to a navigation point from the stored landmark information when moving along a route. The navigation unit guides the navigation point by use of the at least one landmark extracted. The determination unit determines, at a position possible to take an image of a characteristic object corresponding to the landmark information thereat, whether the characteristic object can be recognized from the obtained image. The navigation unit guides the navigation point after omitting a landmark corresponding to the characteristic object from the at least one extracted landmark if the determination unit determines that the characteristic object cannot be recognized.

Abstract: A navigation device provides route guidance only by voice guidance even if route guidance by a display screen is impossible. A navigation device displays on a display device a navigation screen including a map about a current position. The display device can enter a no-display state. In the navigation device, regardless of the state of the navigation screen, a route guidance method is performed. More particularly, in the display state, a guidance route is determined by a normal mode and route guidance is performed by both voice and display. In the no-display state, a guidance route including fewer movement methods is determined and route guidance is made only by voice guidance. Thus, in the no-display state where the navigation screen is not displayed, a guidance route is determined so as to enable route guidance only by voice.
