Embodiment approach 1

[0024] figure 1 It is a block diagram showing the system configuration of the car navigation device in the first embodiment. In this figure, a key input unit 1 (operation unit) inputs a user's instruction according to a user's operation. The sensor input unit 2 (information input means) inputs information such as the current position, direction, and speed of the vehicle from a GPS receiver, a gyroscope, a speed sensor, and the like. The data storage unit 3 temporarily stores map data and data necessary for navigation processing. The data processing unit 4 processes various data for navigation. The electroencephalogram detection unit 5 (instruction detection means, electroencephalogram detection means) detects electroencephalograms from electrodes that are in contact with or not in contact with the driver's head, and outputs electroencephalogram signals (instruction signals). The electroencephalogram interface unit 6 amplifies the electroencephalogram signal output from the ...

Embodiment approach 2

[0050] FIG. 10 is a block diagram showing a system configuration of a vehicle navigation device in Embodiment 2. FIG. in the figure, with figure 1 Components that are substantially the same as in the first embodiment shown are denoted by the same symbols, and descriptions that overlap with those in the first embodiment are omitted. In FIG. 10 , the voice recognition processing unit 10 (voice recognition unit) receives a voice signal from a loudspeaker or the like that detects the voice of the driver and generates a voice signal, generates a voice recognition signal, and sends it to the signal processing unit 73 of the arithmetic processing unit 7. . Therefore, the signal processing section 73 has different figure 1 The internal structure shown.

[0051] Figure 11 It is a block diagram showing the internal configuration of the signal processing unit 73 and the relationship with the electroencephalogram processing unit 71 and the speech recognition processing unit 10 . As ...

Abstract

In the electroencephalogram processing unit (71), a variety of pre-stored correction patterns are compared with the correction patterns of the electroencephalogram signal to determine whether there is a consistent correction pattern, and if there is a consistent correction pattern, based on the detected The displayed current position and the displayed current position are used to determine whether the correction instruction is appropriate. When the correction instruction is appropriate, the displayed image at the current position is corrected according to the correction instruction. In this way, when the displayed position of the vehicle is different from the actual position, the displayed position can be corrected even while the vehicle is traveling without requiring troublesome calibration work.

Description

technical field [0001] The present invention relates to a navigation device for guiding the travel of mobile bodies such as vehicles and ships. Background technique [0002] In the conventional navigation device, there has been proposed a dangerous action notification that can improve operational safety by detecting the danger before the action and notifying the user when an operationally dangerous action is about to be performed. functional technology. [0003] According to the structure of this proposal, in the navigation device in which the current position is determined based on the GPS signal by the GPS antenna unit, and the information on the CD-ROM is read and displayed by the CD access unit based on the current position, the information obtained by the CD access unit is After the map information centering on the current position obtained by the GPS antenna unit is obtained, the road detection unit searches for a road that has the possibility of continuing on. Based...
