Early notification warning system for prototype head-up display: development and evaluation of traffic congestion and sharp turn warnings

This paper presents the design and development of a prototype Head-Up Display (HUD) interface that offer early notification warnings of potential collisions under unfavourable weather and traffic conditions. In this work we particularly focus our effort in the embedment of traffic congestion and sharp turn visual warnings in a working prototype interface. In turn we present the results of a large scale evaluation of the system on a group of forty users, which contrasted the use of the proposed HUD against a typical HDD. Finally the paper offers suggestions for further research and a tentative plan for future work.
