The 9D television developed by the University of Sussex
A prism sprays small bursts of smelly vapour towards the nose while pulses of air are fired at the hand to tease the senses: this is '9D' television.
On screen, when Baymax – the animated inflatable star of Big Hero 6 – springs a leak, air is pulsed from a haptic device onto the palm of the viewer.
In the microgravity of Interstellar, a sharp burst of air hits the hand at the precise moment a small asteroid crashes into Matthew McConaughey's spacecraft.
Similar technology is already breaking into other forms of entertainment; touch feedback is being developed for gaming and smells can already be sent via mobile phone.
Television systems of the future could put the watcher in the driving seat of a car chase, where every bump in the road is felt, or transmit the smells from the kitchen of a cookery show.
But transmitted feelings are limited by the hand having to be kept above the haptic interface.
