The RealHelmet project focuses on develop a helmet and its integrated system of visualization of virtual images that can be superimposed on the real image, so that the driver can receive this information without interfering in safe and comfortable driving. In the framework of the consortium comprised by Shiro Helmets (leader), SnellOptics, CETEM and CD6 UPC and with the funding received from the Ministry of Economy and Competitiveness through the program RETOS Colaboración (RTC -2016-5125-4), the project closes the first annuity with the design and implementation of the first functional monocular prototype of HMD (Head-Mounted Display).
