Location based mobile websites

Goal is to provide a usable geo location framework for mobile websites/widget applications. It wraps the underlying platform specific implementation through a simple JavaScriptAPI that is aligned to the W3 Geolocation API Specification.. //determine if the handset has client side geo location capabilities if(geo_position_js.init()){ geo_position_js.getCurrentPosition(success_callback,error_callback); } else{ alert("Functionality not available"); }

Usage Scenario

The framework provides two key methods, it determines if the handset has client side geo location capabilities and one method to retrieve the location (of course only after a request for permission). So a mobile web site that provides location based services can first determine if the client has client side geo capabilites and ask him to assist him in finding his location. If no geo capabilities are given or they are disabled the site can fallback on a manual location input method and use a geodata database/service to map the input to a pair of latitude/longitude coordinates.

Simulation

To assist engineers in the development phase it provides a simple mechanism to simulate users locations and movements without being there in the real world.

Sample Web Pages

• Very simple page that provides a status alert box
• Show the users location in an embedded google map(v3), requires advanced browsers
• Simulates a moving user in an embedded google map(v3), requires advanced browsers

Sample Apps

• Nokia Web Run-Time Sample - download and transfer to the device
