Paper Abstract

The authors developed the handy route guidance system using a laser illuminated direction indicator. This system is applicable to the route guidance anywhere. This route guide system consists of a GPS receiver, a digital compass, a laser illumination and a portable computer for system integration. To indicate the direction, the navigation system needs to study a position on the earth. The information about a direction and a location is obtained by the GPS receiver and the digital compass. The laser illumination directly projects the direction indicator on the ground. The IC processor compares which the direction of a sensor is the same where a user should go or not while the user turns one revolution. Then the handy navigator lights a laser illuminator which shows the indicator on the ground if the direction is the same. Thus our navigation unit requests users to do exercise for an interaction to the earth.
