Evaluation of a simulated vehicle functionality feature

A vehicle feature evaluation system for enabling evaluation of a simulated vehicle functionality feature, the vehicle feature evaluation system comprising:

• a memory storing instructions executed by a processor for providing:
• a HMD orientation determining unit for determining in relation to a road-driven vehicle, with support from a tracking system, an orientation of a head-mounted display, HMD, adapted to be worn by an occupant on-board the road-driven vehicle;
• a feature determining unit for determining a simulated vehicle functionality feature to be evaluated in the road-driven vehicle;
• a HMD providing unit for providing in real-time to a HMD display of the HMD, taking into consideration the HMD orientation, a virtual representation of the simulated vehicle functionality feature superimposed on a real-time real-world video stream derived from real-world image data captured with support from one or more forward-facing cameras provided on the HMD in eye-position of the occupant;
• a vehicle signal updating unit for updating the virtual representation based on a vehicle signal affecting the simulated vehicle functionality feature, derived from the road-driven vehicle, wherein the simulated vehicle functionality feature comprises a simulated effect resulting from a simulation of the simulated vehicle functionality feature.
