13 June 2014 Smart filters: operational HMD even at bright sunlight conditions

A typical Head Mounted Display (HMD) has either one or two small displays with relevant optics embedded in a helmet, eye-glasses (also known as data glasses) or visor. See-through HMDs provide the ability of superimposed the generated image on a real-world view. When using a see-through HMD at a very bright day, the display image risks vanishing due to the sun illumination. However, at a very cloudy day, one needs all the light to pass through the display to the user eye. The need to control the amount of sunlight passes through the HMD in a passive way was the trigger for our effort in developing Dynamic Sunlight Filter (DSF™). DSF™ is a passive solution which is dedicated to regulate sunlight overpower events.
