1. Technical Field
The present disclosure relates to wireless direction systems and methods, and particularly to a wireless direction system and method for providing timely service information.
2. Description of Related Art
Currently, displays are often provided for generating and displaying service information, such as directions in a park or exhibition venue. The information may also be provided in the form of audio output, literature, and other similar ways to attract. However, with these methods, time must be spent locating the displays or other devices before the information can be delivered.
Referring to
The portable device 50 includes a GPS receiver 502, a processor 503, and a memory 506 connected to the GPS receiver 502 and the processor 503. The memory 506 includes a comparison module 512 and a service information processing module 513, each of which stores one or more computerized instructions to be executed by the processor 503.
The GPS receiver 502 receives signals output from the plurality of satellites 10 after every predetermined interval, for example, three minutes, and calculates location coordinates of the portable device 50. In one embodiment, the location coordinates of the portable device 50 may include a longitude, a latitude, and an altitude of the portable device 50.
The comparison module 512 logs onto the data server 20 via the base station 40 by wireless internet access, and determines whether service information corresponding to the location coordinates of the portable device 50 is present on the data server 20. The comparison module 512 sends the service information to the service information processing module 513 in response to successful locating of the service information corresponding to the location coordinates of the portable device 50.
The service information processing module 513 receives the service information and provides it to users.
In step S100, the GPS receiver 502 receives signals output from the plurality of satellites 10, and calculates location coordinates of the portable device 50.
In step S102, the comparison module 512 logs onto the data server 20 via the base station 40 by wireless internet access, and determines whether service information corresponding to the location coordinates of the portable device 50 is present on the data server 20. If the service information corresponding to the location coordinates of the portable device 50 is located, step S104 is implemented. If not, step S100 is repeated.
In step S104, the comparison module 512 sends the service information to the service information processing module 513.
In step S106, the service information processing module 513 receives the service information and provides it to users, and the procedure returns to step S100.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
