For as long as there has been projection, there has been a presenter pinned to the side walls or half way back up the room so as to avoid the dazzling glare from the projector bulb. Someone has finally come up with a "Dream" solution...software.
Dream Beamer software protects the eyes of anyone inside a projector beam by tracking people in front of the projector beam and then blacking out that section of the projected image. Viacheslav Sabirov apparently thought of the idea after seeing university lecturers suffer from the glare for hours every day
Viacheslav says “Even projector manufacturers say in their manuals that the time of eye exposure to projector light must be strictly limited, otherwise it can cause harm to retina. Many of the people I interviewed complained of eye discomfort and headaches.”
The product has been under construction since 2013 when he recruited software developers as well as technical and medical professors with industry experience.
Recent advances in the interactive projector technology have made this idea a reality, “there was no inexpensive method of doing precise tracking of the presenter until recently-- it is still tough but now possible,” says the Dream Beamer inventor.
a 3D sensory is fed through the PC which recognises people stood in front of the projector, it then acts as a middle man between the image that's supposed to be projected at that moment and adds in a black image where the presenter is stood. This means that in theory the software can work with any projector.
The idea is to sell the software with a webcam type system to form one package and sell it on to projector manufacturers.“We already have an agreement with company called 3D-tek which is going to build a line of projectors. Our software will run on 3D-tek's projector hardware,” says Sabirov, but it could also just work as an add-on for existing projector users too.
Our "vision is that all projectors must have the feature onboard as it can cost less than $5 if we are talking about mass production.”
