prateeksikka Posted April 27, 2005 Report Share Posted April 27, 2005 HI ALL!ONCE WE HAVE SUCCESSFULLY MADE TOUCH SENSORS USING SWITCHES,PIEZOELECTRIC CRYSTALS ,POTS ETC AND EVEN PROXIMITY SENSORS USING LIGHT RAYS AND ALSO MAGNETIC FILELD,HOW FAR WE ARE FROM THE SIGHT SENSOR THAT GIVES OUTPUT WHEN WE LOOK AT IT.IS ANYONE WORKING OVER IT? :-\PRATEEK Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 27, 2005 Report Share Posted April 27, 2005 A sensor could easily detect the X-ray vision of Superman, but usually our vision doesn't emit anything for a sensor to detect. Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted April 27, 2005 Report Share Posted April 27, 2005 Some virtual reality head sets and tell where your eyes are looking by reflectig a low powered infrared beam of your retina. Lets not forget iris scanners that can identify people. Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted April 27, 2005 Author Report Share Posted April 27, 2005 hi alun!I too have heard about these types but just heard! :Di think the light will still reflect from our retina even if we are looking at some other place.I mean it should sense it when we look at it.Is it possible or we have to become all SUPERMANS! as audioguru said! 8)prateek Quote Link to comment Share on other sites More sharing options...
Guest Alun Posted April 27, 2005 Report Share Posted April 27, 2005 prateeksikka ,Imadgine the retina acts lik a mirror to infra red light. You can stand in front of the window on a sunny day and reflect the sunlight around the room with a small mirror or watch. The virtuality reality head set could work on the same principle.

prateeksikka Posted April 30, 2005 Author Report Share Posted April 30, 2005 i wish to get an idea for a sensor !which people should see to get the o/p.it should not give out any source of its own.Flashing light is not the property if the sensor.Moreover i dont wish to make people blind for this stupid project. ;Dprateek Quote Link to comment Share on other sites More sharing options...

prateeksikka Posted May 2, 2005 Author Report Share Posted May 2, 2005 HI MP!THE LINK GIVEN BY YOU GIVES THE SPECTRUM OF WHITE LIGHT ,THE WAVELENGTH AND FREQUENCIES.BUT I WISH TO KNOW WHAT THING WOULD YOU EXPLOIT FROM THE HUMAN EYE TO GET THE OUTPUT?LIKE IF I RADIATE LIGHT AND RECIEVE IT BACK,HOW TO JUDGE THAT IT HAS REFLECTED FROM THE RETINA AND NOT MY GLASS WINDOW PANE? :-\PRATEEK Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted May 11, 2005 Author Report Share Posted May 11, 2005 hi there!any other project related to light with anybody if the eyesight sensor is not possible? ???prateek Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted May 11, 2005 Author Report Share Posted May 11, 2005 HI THERE!YOU MEAN TO SAY A PROJECT WHICH CAN BE CALLED A COLOUR DETECTOR?WHICH TELLS ME THE COLOR OF THE OBJECT IT SEES?PRATEEK :) Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted May 11, 2005 Author Report Share Posted May 11, 2005 hey all!any ideas for the color detector? ;Dprateek Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted May 17, 2005 Author Report Share Posted May 17, 2005 hi there!for colour sensing,is it the wavelength only that can i use?any other property by virtue of which the colors differ? ::)prateek Quote Link to comment Share on other sites More sharing options...
audioguru Posted May 17, 2005 Report Share Posted May 17, 2005 Your eyes detect only red, green and blue with some overlap. Your brain determines colours in between and can be fooled.As example, the colour Yellow emits a wavelength between red and green. If you look at a red object and a green object that are close together, like a red/green LED, your brain thinks it is yellow. ;D Quote Link to comment Share on other sites More sharing options...
