Abstract
Light Blue Optics’ holographic laser projection technology can be utilised to create a virtual image display which, with a volume enclosing less than 700cc, exhibits a form-factor consistent with integration into a rear-view mirror. By combining the visual accommodation and concomitant reaction time benefits of a head-up display with the ability to present high resolution safety-critical information in a rear-view off-axis configuration with large eyebox, significant potential safety benefits can result. shown [7], the necessity to re-accommodate focus when transitioning between the outside world and instrumentation displays, and the amount of visual scanning required to absorb this information, imposes a significant time penalty on the driver’s ability to recognise and act on such information. For these reasons, it seems that integrating a conventional display into a rear-view mirror would negate any potential BSW safety.
