The benefits of Cybathlon are overwhelming according to our readers

At the end of last week we launched a survey to find out whether our readers felt Cybathlon would be capable of advancing assistive technology, whether more should be done to encourage participation and whether people would watch the event on television… and the results are in.

As you can see, it seems that the consensus is that Cybathlon will help improve and develop assistive technology for people with disabilities – nobody said it wouldn’t. The coming together of great scientific and engineering brains for the event is likely to see great steps made towards more efficient and useable technology.

AUDIO: The impact of the London 2012 Paralympic games and David Weir on disability sports and what that means for Cybathlon 2016

Inside Cybathlon’s Sam Dean spoke to ESPN and Sunday Times sport journalist Justin Guthrie in the News UK building at London Bridge about what we can learn from the staggering success of the Paralympic Games in 2012.

Guthrie makes the point that the attention the Paralympics was given as a standalone event, coupled with a change in perceptions towards sport in recent years – as well as attitudes towards disabilities in society in general – have provided Cybathlon with the perfect platform from which to succeed.

VIDEO: Brainstormers and BCIs: On your marks, set… think!

Deep in the bowels of Essex University, sitting far below the student hubbub of shops, bars and hangovers, some of the most intelligent researchers in the country are plotting.

Plotting new ways to improve the lives of thousands of disabled people. Plotting innovative technologies which have never been seen before. Plotting their assault on the 2016 Cybathlon championship.

The aptly named Brainstormers, a team of scientists at the School of Computer Science and Electronic Engineering, will be competing in next year’s event as an aside from their revolutionary studies into brain computer interfaces (BCIs).

Hidden away down a few damp flights of stairs and a long, thin corridor filled with identical doors and not much noise, it would be easy to forget that the Brainstormers are living on the front lines of one of the most exciting pieces of technology in the UK.

BCIs are still developing, but they essentially allow the Brainstormers (and others across the world such as scientists at the Center for Integrative Neuroscience at Berkeley and the Life Science Center in Tokyo) to capture brain signals and turn them into commands.

In other words, they let you communicate without speaking or moving – meaning humans will be able to operate computers, robots or virtual reality environments using just neurosignals, even if they have no control of their muscles.

The Brainstormers team consists of five PhD students: team leader Ana Matran-Fernandez, Youngjae Song, Davide Valeriani, Amir Jahangiri, Dimitrios Andreou and Cambridge University’s Christian O’Connell. Working alongside them are Dr. Javier Asensio-Cubero and Dr. Francisco Sepulveda.

Matran-Fernandez says the technology – if developed properly – can have a massive impact on those that need help communicating and says Cybathlon will be the perfect place to showcase the potential of these interfaces.

“We think Cybathlon is going to be really good for BCIs,” she said.”So when we read about Cybathlon we thought it would be a great way to get known by external people and try to help.

“It’s going to expose the field so more people will know about it and that’s great because they have the potential to do a lot of good.”

BCIs won’t just be shaping the field for disabled people, though. As Sepulveda points out, they could also have a huge impact on the gaming industry as companies and competitors look for new, imaginative ways to test themselves.

With the support of BioSemi, one of the nation’s leading electro-physiologic equipment suppliers, the team are currently on the hunt for a pilot to compete as part of the Brainstormers team.

“Between now and Cybathlon, we will first be looking for more sponsors and we’ll also be looking for a pilot, which is the main difficulty at this point,” Matran-Fernandez says.

“Other than that, we’re going to be training hard for the mock test and hopefully we will have someone to help do that. Once we do, we’ll know how things are and we’ll be able to be more specific with our preparation.”

But how does it work? We were shown into a small windowless room in a corner where the machine was kept as Youngjae Song put the equipment on – a lovely piece of gear which looked like a washed-out red swimming cap, except it was crawling with worm-like wires, which pick up the neurosignals.

“When you’re using the interface, you display something on the screen and you can time the brain signals based on what is being played and interpret them one way or the other,” Matran-Fernandez explains.

Although their game involves either a car or a horse, which pilots have to turn round obstacles and past corners, that may change in the competition itself.

“We don’t really know what Cybathlon is going to be like but what we’re expecting is some sort of track and racing video game which the pilot sees on his screen.  What we think is going to happen is that the person has to drive the car to the left or the right,” she says as we watch the game in motion.

“We will ask them to think and move the car, so they think of moving their left hand or foot, or right hand or foot and the car will move in that direction. That’s one of the several types of games there are.”

Of course, it’s not completely flawless technology at the moment, as Dr. Asensio-Cubero points out.

“It’s not really accurate or reliable – you may get 60 per cent accuracy or maybe 80 per cent if the subject is really good,” he says. “This event requires a really high standard of pilot.”

Another way of working with BCIs is to examine “P300” signals – brainwaves which appear soon after the presentation of a stimulus of interest, according to Matran-Fernandez.

“So if you’re shown what we call ‘distractors’, and you see the thing you’re looking for which is of interest, your brain produces these signals and the computer will know what you’re interested in.

“Based on that, there are games called ‘Spellers’. With these, there are lots of rows of letters or numbers, and when a row or column which contains the letter you want flashes we can see it on the screen.”

Sound simple? Maybe. Does it look simple? Not at all. These rows and numbers flashed at such speed that it was exhausting just looking at it, let alone trying to spell a word by focusing on individual symbols.

But with a skilled and experienced pilot, it’s clear to see how this technology could change the lives of people who are ‘locked-in’ and cannot communicate in other way.

“It’s for people who cannot even move their eyes,” says Asensio-Cubero. Nothing hits home how important their work is better than that sentence.

BCIs are perhaps the most iconic event in Cybathlon – nothing else pushes the boundaries of technology quite so far. Although crouching in the basements of Colchester with barely any natural light certainly adds to the experience, it’s clear to see that this is a remarkable concept using remarkable technology. And, frankly, as we watched Song twist and turn a virtual car on a virtual track using just his thoughts, it’s fair to say that it’s remarkably cool.

Cybathlon – what’s that?

Don’t worry, you really aren’t the only person who has no idea what Cybathlon is. From an initial survey, ideas for what it could possibly be were varied, from a “marathon on the internet” to a “triathlon with different forms of cycling”.

Judging by the red line that currently appears underneath the word Cybathlon, Microsoft doesn’t have a clue what it is either. And to be totally honest with you – our readers – neither did we until a fortnight ago.

But in a short space of time, with the help of the team at NCCR Robotics (a group of robotics-focused Swiss institutes who are the presenting sponsors of Cybathlon) and the following trailer, we have become completely enthralled by this idea:

Over the next two years the world will gradually be introduced to the concept, and in October 2016 the spotlight will shine on Zurich for the world’s very first Cybathlon.

The idea of Cybathlon explained

The Cybathlon will be the first championship for bionic athletes, from leg or arm amputees to those with such severe disabilities they are confined to a wheelchair or an exoskeleton (essentially a full-body robotic suit).

We sought the help of Linda Seward, Communications Officer at NCCR Robotics, to explain how the idea emerged.

“It came about from Robert Riener, who is a professor at ETH Zurich, who studies prosthetics and how to get prosthetics to work with the person,” she said.

“A lot of the prosthetics that you have now are hard, difficult to wear, they’re certainly something you can only wear for a few hours, and it’s very uncomfortable trying to wear things all day.

“We’re at a point where we’ve got lots of different technologies which are really, truly fantastic, and can do amazing things. But they’re not ready to send out to market yet, there needs to be more development.

She added that the project was about ‘taking state-of-the-art robotics technologies and making them usable’.

How will Cybathlon work?

Teams consisting of one athlete and a group of technicians will come together from across the world to compete in the following six disciplines:

The timed tasks that the athletes (or pilots, as the founders like to call them) are required to carry out are based around daily life, from sitting down on a sofa in an exoskeleton and standing back up again, to navigating a gravel path in a wheelchair.

This is where Cybathlon differs from the Paralympics, which mainly celebrates the fastest or strongest para-athletes.

“We want to enable people to be able to use their body again. And we want people to understand that that’s what we’re doing so that people get behind it, and are excited by it,” said Linda.

Cybathlon really is about the average disabled person, and gearing the development of robotic technology to help them.
