This document summarizes a GPS logger and speedometer device that projects driving data like speed and time onto a vehicle's windshield using a head-up display. It allows drivers to keep their eyes on the road by not having to look down at the speedometer. The device gets the true speed from GPS rather than just relying on the car's speedometer. It has features like logging location data, overspeed warnings, and online data analysis. It is designed to be a low-cost solution for fleet management needs with an easy plug-and-play installation.
