Location based advertising
Where can we make use of location based advertising ? Definitely it has to be on something that moves. Mobile, yes, but not this time. This about buses. All these buses travel many places, and most of the new ones have got electronic billboards. Why not run location based advertisements on them. The idea is to create a directory of locations (latitude and longitude) and advertisements.
An algorithm needs to be developed to find proximity to a location and change the advertisement based on that. Due to the complexity of the project, its better implemented on an embedded linux box. Coupled with GPRS, the advertisements can be updated on the fly, with out even having to stop the vehicle. The different modules of the project include an LED display controller, a GPS module and GPRS handler.
