Data Science and Disability
Data Science and Artificial Intelligence has come to the forefront of technology in the last few years. Learn, how practitioners are taking a more philanthropic outlook on life, supporting people suffering with both physical and mental disabilities.
2012 was a big year in Great Britain. The country was awash with national pride. Union Jacks proudly flying at full mast across most British streets and a feverish party atmosphere, as we hosted arguably the best ever Olympic Games. During the games, we witnessed the prominent rise and rightful public recognition of the athleticism of disabled athletes, competing in the Paralympics and Special Olympics. Tanni Grey-Thompson, Ellie Simmonds and Lee Pearson are now just as likely to be debated as Britain’s best Olympians from those games, alongside Mo Farah and Bradley Wiggins, amongst friends down the pub. Whatever stigma previously existed was smashed to bits, as our heroic athletes brought home gold medal after gold medal.
As a result of the games, we are now seeing society becoming far more understanding and inclusive of the disabled community, but with the United Nations reporting that around 15% of the world’s population suffer with some type of disability, there is a growing feeling that we need to do more, to help make the lives of people with disabilities easier.
Data Science and Artificial Intelligence has come to the forefront of technology in the last few years, and several practitioners are taking a more philanthropic outlook on life, supporting people suffering with both physical and mental disabilities.
One of the areas where Machine Learning is playing a prominent role, is the support of people suffering with Autism Spectrum Disorder (ASD), which is a condition suffered by approximately 1 in every 100 people, with men more likely to be diagnosed with the condition than women. It affects children at around age 3, and results in the child having difficulty processing or engaging in human interaction or emotion, which can make integrating into groups of other children very difficult. However, the London Knowledge Lab was incredibly successful in introducing a group of ASD children to a virtual autonomous robot called Andy. The experiment found that the children interacted readily with Andy, listening intently, asking and answering questions far more freely than if it had been a human adult. Similarly, an artificial intelligence robot called Milo has been rolled out to over 50 schools in the United States to encourage children with ASD to interact more readily face to face, and in some cases, even permit physical contact from the robot, unthinkable for the majority of ASD sufferers. While there is no recognised cure for ASD at present, the experiment offers hope to the families of children and adults suffering with ASD, that they might one day be so comfortable conversing with artificial intelligence software that they might grow in confidence in their interactions with other people.
Intelligent prosthetics is another area in which Data Science has been implemented in order to make the lives of disabled people easier. For many amputees or people living without the use of one or more limbs, the options are very limited, and often very rudimentary, focusing on bare essential rather than everyday usability. However, Deka Research, headed up by Segway inventor Dean Kamen, have pioneered a prosthesis they call the ‘Luke’ arm (named in tribute after Luke Skywalker). The unique aspect of this piece of technology is that its modelled more closely on the internal workings of a human arm, with the mechanical equivalent of tendons, muscles and bones allowing the user a much more natural range of motion, closer to a human arm than to the hooks and claws that have been more prevalent in the last 20 years. The arm itself can be controlled in several ways: with microscopic nerve endings attached to the base of the arm, or controllers in the wearer’s shoes. The project was granted a significant financial boost by the US Army Research Office, but the prostheses are likely to still be incredibly expensive to produce on a mass scale, with some estimates at around the $50,000 mark. While this may not be the answer for everyone who needs a prosthetic, the range of movement and sophistication of technology on show here is a brilliant sign for the future, when similar technologies will be available for less cost, and potentially with even more uses.
A piece of technology that was brought to prominence by one of the world’s most famous scientists, Professor Stephen Hawking, the electronic augmentative and alternative communication system (AAC) has become integral to the lives of those people who are unable to speak due to conditions such as motor neurone disease or cerebral palsy. One of the latest innovations in this market, and still closely related to the ‘Equaliser’ device used by Hawking from 1986 onwards, is the DynaVox EyeMax. This device uses Computer Vision techniques, via a front-facing camera to track the movements of the user’s eyes across the screen of commands, and can even be programmed to use certain intonation in order for the speech to not be misconstrued. It has the potential to use Natural Language Processing to give speech to a large number of people who may have lost the ability, but there are some limitations to the technology; each device must be individually programmed for the respective user, to include places of interest, names of friends and family and other unique information, and the cost of the devices is not often covered by health insurance. It is expected however that the inclusion of deep learning technology into the devices in future should reduce the time taken to program the device, which could bring the cost of the devices down to a more affordable level.
It is not only specialist medical firms who have seen the value, both financially and philanthropically, of using data science technologies to improve the lives of disabled people. Google recently announced that they were looking to boost the accessibility of their smartphones and other devices for users who might have limited or no use of their sight, hearing or dexterity. One of the most exciting and unique developments is a Braille system for use with Google smartphones, which allows users to connect a Braille device to their phone via Bluetooth. In addition, Android systems can now be controlled by ‘switches’, not dissimilar to those used by Stephen Hawking in his wheelchair. This, according to Google, opens them up to a new group of users who previously would not have been able to access this technology, and allows users to use the same hardware as their friends rather than having something custom-made and potentially less appealing. There is a huge financial incentive to these developments, as both Switch Access and BrailleBack are free to download for Android, meaning that unlike many technologies designed for the disabled community, price does not have to be a barrier. Overall, Google’s contribution has laid down a benchmark for other technology companies to follow their lead in producing affordable and easy-to-use platforms for those with disabilities, and we look forward to see who steps up next.
Finally, there is something that is definitely more at the ‘proof of concept’ stage right now, but shows enormous potential for the future. In 2011 Dr Dennis Hong, from Virginia Tech University’s RoMeLa Robotics and Mechanisms Laboratory, pioneered a car that was designed for blind or partially-sighted people to be able to drive independently. Using a system that combined machine learning software that was able to learn a pre-determined route and sense obstacles and pedestrians, and a series of sensors packed into pressure-pad gloves, that would tell the driver where they should be going and if there was an impeding obstacle that needed to be avoided. During his TED talk in the same year, Dr Hong demonstrated the car with a blind person driving, doing a whole lap of a pre-determined course safely at the Daytona Speedway. It must be noted that there are a few reasons why this system could not be implemented immediately, least of which is that the route had to be meticulously entered into the car’s computer in order for the sensors to direct the driver, and this would not be feasible for every road. However, it shows enormous progress in the field of Data Science and Machine Learning, and a huge leap forward for the blind and partially sighted community as a whole.
There are several questions that must be addressed before the relationship between Data Science and Disability can be labelled a success. Firstly, are the technological innovations that are beginning to emerge at an advanced enough stage to benefit those who are suffering from a disability now, or is the real breakthrough likely to come in 5-10 years? Similarly, are these options all financially viable, not for the producer, but for the consumer, who might only have limited income as a result of their income? Furthermore, are innovations offered by Data Science limited to making the lives of disabled people easier, or is there scope, for example, for deep learning being used to identify the genes that cause certain disabilities, giving doctors the chance to study and limit the genes in the future?
The future for Data Science looks incredibly bright, as several innovations are already making marked differences to the lives of disabled people around the world. The next step, whether that be into genetics research, deep learning integration or another field, is dependent on whether many of the major companies will look past the finance sheets and instead look to improve the lives of the many millions of disabled people all over the world. Let’s hope it doesn’t have to take until the next Olympic Games, until they do.
