The present invention relates to a navigation system, and more particularly, a pointing device which can be worn on a driver's or user's finger, and which has a built-in direction sensor and an inclination sensor and is capable of pointing so as to be interlocked with a vehicle navigation intention to point to an actual building. Not only detailed information such as parking information or store information of a building can be provided, but also various information according to the direction can be provided by pointing the direction, thereby preventing the driver's eyes from moving to the navigation screen while driving. In addition, the present invention relates to an intuitive navigation system capable of pointing by using a direction sensor and an inclination sensor capable of providing a safe driving by reducing an operation burden of the navigation by providing an intuitive method and an intuitive pointing method accordingly.

In general, the navigation system is developed by the US Department of Defense for military purposes and uses the information received from the Global Positioning System (GPS), which has been launched over 21,000 meters. It refers to a system that displays a direction and recognizes it to a moving object, and has recently been applied to vehicles such as automobiles.

Here, the principle of GPS is that GPS satellites have a highly precise clock and a signal propagation device for informing the orbital position, so that accurate time information and orbital position information is simultaneously provided when the radio wave is transmitted, and the radio waves from the GPS satellites are input to the navigation. It calculates the difference from the time difference it takes until the navigation is received.

For example, to find out the difference in distance by applying "propagation speed (approximately 200,000 Km / s) × time difference", and using only satellite information, the error of the position change in the stationary state due to the circular motion of satellite High precision timers are built into the navigation to prevent and correct them.

In this case, two-dimensional measurements (latitude and longitude) can be received from three satellites due to the application of triangulation, but because of the large error range, three satellites for more accurate position measurement and one satellite for time correction, In other words, it is more accurate to measure three-dimensional latitude, longitude, and altitude through four or more satellites.

Currently, such navigation is applied to a variety of applications such as air, sea, and vehicles, and the navigation applied to a vehicle guides the direction and distance of travel from the driver's starting point to the destination or destination by video and audio. Do it.
