How IoT is changing health

Published

The healthcare industry has cottoned onto the IoT with a range of devices entering the market, designed to improve the lives of patients and healthcare practitioners, writes ANDRE DEETLEFS, Executive: Lines of Business & Enterprise, The Jasco Group.

The Internet of Things is evolving quickly, and on a global scale. The healthcare industry has cottoned on to this trend and already we are seeing a host of applications and connected devices entering the market, bearing the promise of improving the lives of patients and healthcare practitioners alike. The benefits of IoT extend well beyond health and fitness monitoring, however, and can help to smooth the interaction process between healthcare and medical aid providers as well as their clients.

The impact of IoT on healthcare

From a healthcare monitoring perspective, the introduction of a variety of connected wearable devices, sensors and health applications have emerged to track a variety of common health concerns. People now have access to a multitude of health-related data from heart rates and fitness levels, to blood pressure, sleep patterns, insulin levels and even the dispensing of medication. These devices – both wearable and in the form of smart phone applications – use the Internet to communicate data back to medical aids and healthcare providers. The steady flow of information keeps them apprised of the health state of the wearer, or user, and helps them to avert worsened conditions.

Healthcare providers and medical aids are finding a wealth of value through the incoming stream of data from these devices. Leveraging the likes of Artificial Intelligence (AI) and Machine Learning (ML), they are able to do more with this data than ever before. Data analysis helps them to track trends and identify common problems, risks and solutions, which enables them to make greater medicinal strides. Many incurable disorders can now be managed easily and in an automated fashion, freeing up doctors’ time for research, and providing patients with better quality of life.

IoT is also helping healthcare providers and medical aids in other areas such as in-hospital vital sign monitoring, inventory and asset tracking and logistics. A key area that remains largely unexplored however, is the benefit of IoT on healthcare contact centres.

IoT improves CX

Customer experience (CX) is lauded as the new mark of customer loyalty. In the digital age, where most services are available at the click of a button, customers move swiftly between service providers when their experience with a provider is less than satisfactory. The same is true of healthcare and medical aid providers.

Many people still experience the frustration of repeatedly providing details to representatives of healthcare or medical aid providers. Time and again customers are prompted for the same information, having to fill in the same forms or needing to confirm the same details with a contact centre agent. A few medical aids and healthcare practitioners, as well as third party organisations however, are discovering that they can tap into the data being generated by connected devices and sensors to auto-complete their customer profiles. By having all their customers’ relevant information centrally stored and on-hand when customers contact them. They are providing better, faster service to customers while simultaneously accessing  vital and accurate information that they require.

While some healthcare providers and medical aids are using IoT technology themselves to verify the accuracy and completeness of their databases, third party organisations are also emerging with applications that assist customers while providing an accessible database to healthcare and insurance providers. This must however be approved by the customer. The likes of Logbox have recently been brought to light in South Africa; an application which collates a person’s medical history and personal information on a secure platform and allows them to share it with doctors, hospitals and medical aid providers. This process helps  save time, while giving providers ease of access to customer information. Connected devices which tie into applications such as Logbox can ensure that data collection is both accurate and automatic.

IoT to prevent fraud

A common issue experienced by both healthcare providers and medical aids, is the incorrect relay of information by customers. For example, a person applying for medical aid may state that they are healthy when in fact they may have a pre-existing medical condition. A sensor or connected device would be able to easily counter such claims, providing the contact centre agent with accurate information on the state of the person’s health, depending on the type of mechanism.

In the event of medical aid claims, IoT devices can also prevent fraud by verifying the authenticity of the individual’s claim. Medical aid contact centre agents would easily be able to access the claimant’s accurate medical history and records, through automated data delivery, and validate the necessity of the procedure.

Fraud from healthcare providers is also a lurking problem. Greedy practitioners may recommend more expensive medication, or unnecessary procedures anticipating higher returns. An analysis of data supplied by an IoT enabled device could easily refute the need for any recommended procedure and may even be able to suggest a more suitable solution, with the ongoing application of AI and ML.

IoT for healthcare

IoT, and more specifically the data it generates, opens the door to a world of possibilities for the healthcare industry. Whether applied to improve lives and control health disorders, or used to track and trace hospital assets; perhaps to administer medication, or facilitate smoother interactions between healthcare providers and customers; or possibly to prevent fraudulent activity, one thing is certain: IoT benefits the entire healthcare value chain and. If not already in use, IoT should form part of any healthcare and medical aid provider’s digital strategy.

Prepare your cam to capture the Blood Moon

On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.

Published

on

Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.

“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.

Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion.   In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.

A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.

David Noton advises:

  1. Download the right apps to be in-the-know

The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky.  Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.

 

  1. Invest in a lens with optimal zoom  

On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.

  1. Use a tripod to capture the intimate details

As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.

  1. Integrate the moon into your landscape

Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.

  1. Master the shutter speed for your subject 

The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability.  By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.

 

On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!

How Africa can embrace AI

Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast, says ZOAIB HOOSEN, Microsoft Managing Director.

To play catch up, we must take advantage of our best and most powerful resource – our human capital. According to a report by the World Economic Forum (WEF), more than 60 percent of the population in sub-Saharan Africa is under the age of 25.

These are the people who are poised to create a future where humans and AI can work together for the good of society. In fact, the most recent WEF Global Shapers survey found that almost 80 percent of youth believe technology like AI is creating jobs rather than destroying them.

Staying ahead of the trends to stay employed

AI developments are expected to impact existing jobs, as AI can replicate certain activities at greater speed and scale. In some areas, AI could learn faster than humans, if not yet as deeply.

According to Gartner, while AI will improve the productivity of many jobs and create millions more new positions, it could impact many others. The simpler and less creative the job, the earlier, a bot for example, could replace it.

It’s important to stay ahead of the trends and find opportunities to expand our knowledge and skills while learning how to work more closely and symbiotically with technology.

Another global study by Accenture, found that the adoption of AI will create several new job categories requiring important and yet surprising skills. These include trainers, who are tasked with teaching AI systems how to perform; explainers, who bridge the gap between technologist and business leader; and sustainers, who ensure that AI systems are operating as designed.

It’s clear that successfully integrating human intelligence with AI, so they co-exist in a two-way learning relationship, will become more critical than ever.

Combining STEM with the arts

Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.

As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.

For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.

“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.

Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.

Revisiting laws and regulation

For this type of evolution to happen, the onus is on policy makers to revisit current laws and even bring in new regulations. Policy makers need to identify the groups most at risk of losing their jobs and create strategies to reintegrate them into the economy.

Simultaneously, though AI could be hugely beneficial in areas such as curbing poor access to healthcare and improving diagnoses for example, physicians may avoid using this technology for fear of malpractice. To avoid this, we need regulation that closes the gap between the pace of technological change and that of regulatory response. It will also become essential to develop a code of ethics for this new ecosystem.

Preparing for the future

With the recent convergence of a transformative set of technologies, economies are entering a period in which AI has the potential overcome physical limitations and open up new sources of value and growth.

To avoid missing out on this opportunity, policy makers and business leaders must prepare for, and work toward, a future with AI. We must do so not with the idea that AI is simply another productivity enhancer. Rather, we must see AI as the tool that can transform our thinking about how growth is created.

It comes down to a choice of our people and economies being part of the technological disruption, or being left behind.
