In 1960, a system called 'Smell-O-Vision' introduced smells into cinemas for the film Scent of Mystery. Audiences could smell thirty different scents during the film, but unfortunately the machines were noisy, so some people could not hear the film. There were also problems with the first 3D films because people could not wear the special glasses for long - they felt sick.
These days we can enjoy 3D films without any problems and it's possible that in the cinemas of the future we will be able to feel the same sensations as the characters. Scientists say that they will be able to connect the audience to computers and stimulate emotions in their brains.
