The Neurotransmitter 3000 is a 7 metre (23 foot) machine that paces itself based on your biometrics.

An ear-clip on the ride measures your heart rate, and muscle sensors measure how tense you are. As it begins to spin you around, the machine detects the numbers and adjusts its speed to match your comfort level.

"So say your heart rate is around 60 bpm, the machine will go full speed...until it goes to about 100 bpm it'll start to slow down and stop completely at above 130 bpm," Daniel de Bruin, the artist and designer behind the machine told Mashable.

"But the slowing down is gradual, it's not sudden."

According to WebMD, the average heart rate of a rollercoaster rider is 155 beats per minute.

De Bruin first came up with the idea two years ago, as part of a desire to fulfil his childhood dream and to make his own thrill ride.

While making it, he realised it could be made more interesting if it could be fed additional data.

He first toggled around with testing using electroencephalography (EEG), a method that detects electrical activity in your brain, but that didn't work out.

"In the end EEG wasn't possible after I discussed it with scientists...so in the end I decided to go for more reliable sources of data and that became muscle tension and heart rate," he adds.

For now, de Bruin adds that he has no plans to develop the machine, but would "love" if it could be developed for larger amusement rides.

"I really would love to see this ride, or this kind of emotional connection be developed for larger amusement park rides," he says.

"[The machine] is kind of taking care of you, and that's something a normal amusement ride doesn't have, you're just left to the guy behind the buttons. This might be for people who want to have their own personal ride and experience."
