Spy camera coming that knows what you are thinking!

Kampala, Uganda | THE INDEPENDENT | The data we share with companies online has become a hot-button issue, but new technologies could soon be scanning us as we go about our day.

Our bodies give off various signals that can be scanned and analysed by advanced computer systems, revealing everything from our current mood to our overall health.

In a similar way to wearable gadgets already available, future devices could be set up throughout public spaces to harvest this valuable bio-data.

The claims were made during a presentation given by Dolby Labs’ chief scientist Poppy Crum, who has spent years studying people’s reactions as they watch films, at the Ted 2018 conference in Vancouver.

Using thermal imaging cameras, ‘mind-reading’ electroencephalogram (EEG) caps, heart rate monitors and skin response sensors, she can watch how volunteer’s bodies and minds respond to what they watch on screen.

And it’s a small step to imagine these techniques making the move to the real world in the near future.  Technologies can already distinguish a real smile from a fake one.
