New Japanese TVs are being developed that are able to watch the viewer and measure their emotional response to what they are seeing on the screen.

Is this a whole new Bladerunner-­esque Big Brother nightmare waiting to happen? Or is it actually a cool new feature that might somehow improve our enjoyment of TV in future?

The new tech comes courtesy of NHK Science & Technology Research Laboratories (STRL) of Japan, who plan to put small cameras in TVs to observe viewers' responses to the content on the goggle-box in front of them.
