GM Project Concept

A GPS Based In-Vehicle Navigation System that not only plans a route or guides a driver along the route, but a system that is also capable of presenting varying levels of driving information, communication information, and internet access to the vehicle operator and passengers.

Concept ProposalWe propose to design and prototype an in-vehicle navigation system that consists of a GPS unit, a laptop pc, a cellular modem, Java based mapping software, an MS Access database of local information, and a small display of LEDs with the associated hardware components. This system will be capable of reacting to GPS coordinate based triggers which will in turn activate information display windows, the LEDs (to simulate a display system), and possibly a text to speech function.

System Design Techniques

Top Down System Engineering approach

Object Oriented software design using the Unified Modeling Language (UML)

Human Factors approach to information push/pull strategy

Data normalization with relational databases

Continuous design feedback and improvement
