3D TV Without Glasses: Lot Of Ground Still To Be Covered
Toshiba and Sony displayed technology that they had developed by which one would not require to wear any glasses to view 3D on the screen. Though the prototype which they had put up on display required the viewer to look through special filters and electronics, yet the idea that such a feature is possible and being researched into is good news so far as 3D format goes. That the possibility is very strong is further strengthened by the fact that Nintendo has come up with such a glassless gaming console that is 3D capable. The TV set which have larger screen and therefore involves more electronics was shown at the CES 2012 and thereafter things have gone a bit slower. This technology has yet a long way to go before it finds its place in the common room or drawing room.
The Nintendo gaming console when used with the 3D feature turned on would require the hand to be held at a particular distance and angle from the player. Only then would the player be able to experience the 3D effect. The player would get flicker effect with any small movement of the head or the hand. In case of the large size TV screens therefore this problem is magnified. Toshiba at the CES with their glasses free prototype did boast of having the eye tracking technology but that also could not do much so far as the distortion and disturbance effects of head movement resulted in. One would even get huge image separation effect with any movement of the head from the perfect angle of viewing.
Sony is also using the glasses free screens on their handy cams which are smaller in screen size than even the Nintendo. Other than that they also have no plans afoot for a commercial version of the prototype they displayed at the CES 2012. It can therefore be safely and surely concluded that glass free 3D gadgets whether in TV or notebooks etc are all in the distant future.
The biggest challenge that developers are facing today in glasses free 3D sets is achieving that wide angle of viewing that 3D viewing glasses are offering its users.
Given the fact that even gamers are not using the 3D feature due to the same restrictive viewing angle and keeping their head fixed at the angle, there is no possibility of the technology moving to the big size TV screens that 3D TV sets have.
Glass less 3D viewing is yet long way off is the bottom line.
