METHOD FOR GENERATING SYMBOL OBJECT OF ROUTE DIRECTION

摘要

A method for displaying a route direction symbol object is capable of receiving information from a service server for generating route information; and displaying a symbol object having directivity in the direction of a progressed route in a screen display means of a user terminal together with an image acquired from a camera mounted on the user terminal. The method comprises an information receiving step of receiving an absolute coordinate value of a route POI from a service server; a direction vector outputting step for outputting an initial direction vector by using a difference between a current location coordinate value generated by a GPS module mounted in a user terminal and the absolute coordinate value of a first route POI which is the route POI closest to the current location coordinate value; an object generating step for generating an initial symbol object having directivity corresponding to the initial direction vector; and an object displaying step for displaying the initial symbol object in a certain area for displaying the current location in a screen display means. [Reference numerals] (10) Service server; (100) Display device; (AA) Yes; (BB) No; (S300) Input departure place or destination information by a user; (S310) Transmit the departure place (or current location information) or destination information; (S320) Generate route information having sequentially aligned route POI; (S330) Transmit a coordinate value of the route POI and a coordinate value of a POI text information destination, etc.; (S340) Calculate a direction vector between an n^th POI and an n+1^th POI; (S350) Generate a symbol object having directivity corresponding to the direction vector; (S370) Display the symbol object in an area corresponding to an absolute coordinate value of the n^th POI; (S380) Calculate vision line angle information such as a rotation direction and a rotation angle, etc.; (S390) Is the display area of the POI included in the vision line angle ?; (S395) Display vision line angle inducing information on a user terminal
