Abstract

In see-through HMD the background illumination is a crucial factor, which influences the ability of viewing the display. When using the HMD at a very bright day, the display image risks vanishing due to sun illumination. However, at a very cloudy day, one needs all the light to pass through the display to the user’s eye. The need for a better light control was our trigger for developing a Dynamic Sunlight Filter (DSF), which is a passive solution dedicated to regulate sunlight overpower events.
