This was the final project for the Human Factors course in Carnegie Mellon University. The goal of our team was to study and research the situation of GPS rerouting during driving, to identify problems and redesign the system.

The aim of our research was to sufficiently understand the drivers' expectation and need in a situation of GPS device rerouting during driving, as well as to study the GPS market and to identify problems and potential opportunities. We did:

  • 2 Think-alouds
  • 6 Interviews
  • Competitive analysis with 4 competitors and 13 dimensions grouped in 5 human factors
    • Visual Perception
    • Audio Perception
    • Cognition / Attention
    • Control
    • Training
Competitive Analysis

Competitive Analysis


From the results of our research, we identified two situations in which GPS rerouting is needed:

  • driver needs to change the destination on the way

  • driver takes a wrong turn, GPS automatically starts recalculating and rerouting

Current GPS devices present a considerable danger in either situations above. We concluded that in such situations, to avoid accidents, drivers need to :

  • free their hands from the GPS device

  • concentrate more on the road rather than the GPS device


Based on the results of our analysis, we designed an augmented reality windshield GPS with voice control , which would fully address the problems we found.

We wrote a final paper and illustrate our design with the graph showed above.
