Head Mounted Displays for lighting in Virtual Reality: Review on Measurements, Advances and Limitations

Virtual reality has made a great progress over the past recent years both in recreational and professional fields. However, several factors can affect the capability of the virtual reality from the realism point of view. Luminance and colour of the stimuli could be considered as the main parameters which participate in this challenge. On the other hand, the complex way that virtual reality software such as the Unreal game engine manipulate the virtual scene before to be sent to the Head Mounted Display, can affect the desired goal. This review tries to have a general overview reached so far on the characterisation done in head mounted displays so as to evaluate the quantity and the quality of the light reaching users’ eyes. Further, a discussion on the open issues in the field is provided as well.
