Abstract
This paper describes a Helmet Mounted display (HMD) based on an augmented reality system applied to car technologies, which is considered as a Head Up display (HUD), using the MAPLE ® software to analyze the system stability during specific environments in order to understand how the optic parameters are affected by the surrounding conditions. The objective of this paper is segmented into two parts, the first one is the recognition of many different optic parameters involved in such systems, which are analyzed using the mixing of a mathematical model and some measurement systems, where the principal idea was to describe the ratios between both aspects; and the second one is the comprehension of how all those parameters are related with the human perception; I found that parameters like FOV(Field Of View), eye relief and MTF (Modulation Transfer Function) are directly related with the image size, and contrast threshold, additionally I conclude that the effectiveness of the system is determinate by the optic elements used and the system array of lens, finally I found some lens structure that could reduce the aberration amounts present in this kind of systems; all these considerations are focused on the developing of a car gadget, but the application of this knowledge is unlimited in optic systems.
