If big data seems to be something remote, think again: it’s becoming a big part of your health picture, writes ARTHUR GOLDSTUCK.
It’s no surprise that the health industry has taken so strongly to fitness tracking devices: every day, these gadgets stream information on a level that previously was only possible from a medical checkup – which takes place only once a year, if at all.
When Microsoft entered the crowded fitness tracker market with its Band device 18 months ago, the big news wasn’t in the device itself. The real story was the launch of Microsoft Health, a wellness tracking platform powered by cloud computing. It wasn’t a first, but the entry of the software giant into an area where the early running seemed to be made by Google Fit and Apple Health was deeply significant.
For one thing, it meant that health tracking was now a priority for a company focused both on leveraging the cloud and making sense of Big Data – the ability to turn massive volumes of information into business intelligence.
It also meant that, regardless of the success of the Band, the platform would evolve to take advantage of the intensifying stream of health data being pumped out by millions of other wearable devices. For now, that market is dominated by Fitbit, Apple Watch, Garmin, Samsung Gear and Jawbone UP. However, a strong push from Chinese manufacturers like Lenovo, Xiaomi and Huawei is likely to change the early shape of the industry.
Even in South Africa, fitness bands or activity trackers are beginning to graduate from fad to trend to mainstream. The local market is led by Fitbit, which at one stage threatened to become the generic name for activity trackers globally. In an interview last year, US president Barack Obama said he was planning to get a Fitbit – but appeared to be talking about the category rather than the brand. He suggested he might consider an Apple Watch.
In the USA, Fitbit sells two-thirds of all activity trackers. For wearables in general, including smart watches, its share drops below half, but it still leads the market. In South Africa, it helped that it was endorsed by Discovery Health, which gave members of the Vitality wellness programme bonus points for using the device. Discovery did the same for brands like Garmin, Nike, Fitbug, Jawbone, Polar and Adidas.
In the near future, it is likely that medical insurance companies will plug into the devices as well as the platforms. Since Microsoft Health also acts as a hub for data from other monitoring platforms, like MapMyFitness, MyFitnessPal and RunKeeper, there is little reason it can’t become a catch-all health data aggregator.
Combine this kind of functionality with information collected by health practitioners – including nutritional assessments and medical check-ups – and it becomes possible to make precise connections between behaviour and health. The significance of the role of big data here is that recommendations can then be made across large populations as well as for specific individuals.
Right now, many individuals who are committed to healthy living depend heavily on health magazines that offer glib and generalised advice as silver bullets, when in fact this represents a scattergun approach. In the near future, big health data will mean that every individual will potentially have access to highly personalised diagnostics and advice.
There will be many pitfalls along this path, such as “wrist spam”, when too much data is offered, and false alerts, when people are for example wrongly warned of impending heart attacks. Privacy will become an increasing challenge, and laws will probably be passed to dictate what information health and life insurance companies may collect, how it must be stored, and how they can use that information to weight insurance premiums.
The biggest threat of all, however, is likely to be security: in the same way many hackers now make a living from stealing financial data, many will in future try to harvest health and activity data for sale to the highest bidders.
The stakes are high, with massive benefits for the main stakeholders: individuals managing their own health destinies; cloud computing companies hosting the data; practitioners providing scientifically tailored care; researchers getting the most accurate insights yet from trials; and insurance companies requiring interventions when anomalies appear. For each of these, it’s the small insights lurking in the big data that will make all the difference.
There will be many not-so-obvious stakeholders too, in particular the companies that manufacture wearable monitoring devices. Knowing what makes the biggest difference in big data will aslo depend increasingly on these small increments in data that each of us is streaming into our devices, and from there into the world.
South Africans are searching in the dark, according to the latest Google Search trends.
With more 1 million search queries generated in the space of 76 hours, load-shedding was by far the top trending search on Google South Africa this week.
Valentine’s Day came a distant second.

Thanks to the growing popularity of video-on-demand services, there’s a new opportunity to help kickstart the careers of local filmmakers.
Numerous Hollywood blockbusters (District 9, Tomb Raider 2018, and The Avengers: Age of Ultron to name a few) have featured substantial shoots in Johannesburg and Cape Town. While providing great opportunities for SA’s production talent, aspiring writers and directors don’t get the same benefit.
So where can local creatives showcase their work? Broadcast TV isn’t a natural home for unknown short films, and while self-publishing platforms are readily available hosting options, it’s tough to get noticed and get traffic when competing with videos from across the planet.
But with the emergence of video-on-demand services into the mainstream, there’s now a solution. The African film school AFDA has teamed up with the streaming service Showmax to give local talent a much larger platform than ever before. From 18 February, eighteen of the best recent short films made by AFDA students from their Johannesburg, Cape Town, Durban and Port Elizabeth campuses will be live on Showmax. Drama, documentary, fantasy, and animation are all represented, in pieces running from under eight minutes to almost half-an-hour long. The full list of movies is included below.
Teresa Passchier, CEO of AFDA, said: “AFDA, Africa’s number-one school for the Creative Economy, is proud to kickstart this exciting and meaningful journey with Showmax and AFDA students, ensuring emerging young African filmmakers’ voices are heard and given a platform. It’s ground-breaking to share young, local, culturally relevant content on the same platform as Hollywood blockbusters. I am certain that this unique initiative will serve to boost and develop the African film industry and the careers of many young South African and African students alike.”
Included in the short films coming to Showmax are the award winners Junior and O-Puncha. Junior, directed by Bert Dijkstra, picked up the Audience Award in the Made in South Africa Competition at the shnit Worldwide Shortfilmfestival Awards 2017. O-Puncha, directed by Adam Hansen, won two awards at the 5th annual Eldorado Film Festival: Best Student Made Short, and Best Editing – Alexander La Cock.
Another celebrated film is Sicela Amanzi directed by Mlu Godola, which talks to the subject of water shortage. The film’s heroine Zoleka is a mild-mannered young woman forced to go to extreme lengths when a small community’s only source of water unexpectedly collapses. The power of films like this is they shine a light on critical topical issues in new ways.
Speaking about working with the film school, Candice Fangueiro, Head of Content for Showmax, said: “There’s
AFDA is an Academy Award-winning institution, founded in 1994, and the first and only African film school to win an Oscar – for the Best Foreign Student film in 2006, the postgraduate film Elalini, directed by Tristan Holmes.
