That way, the new drug can be tested against existing drugs or against a placebo – or both.Ī similar method, involving three groups of participants, could test the effectiveness of wearable fitness trackers. One group of patients is given the drug that is being tested, and other groups (the control groups) might be given a different drug or a placebo. When a drug is tested on humans, a randomised controlled trial is the gold standard for testing efficacy. Researching new designs should aim to adopt a similar approach to that of a standard drug trial in order to demonstrate the effectiveness of fitness trackers before they come to market. This could lead to data being lost, stolen or distorted.ĭevices are sold on the premise that they will help improve fitness, even though the evidence is currently lacking. It's not clear how this data is kept secure or anonymised given that any device that transmits data remotely can be hacked. "Raw data" is stored by the manufacturer and is regularly sold to other organisations. Error rates of some devices are as high as 25%.Īlso, a consumer typically doesn't own the data collected by their device and is only permitted to view summary statistics. When it comes to comparing different devices, accuracy varies considerably. Of course all this assumes that these devices are accurate and secure in the first instance. (Compare this with a wrist watch that may need a new battery once every couple of years.)Ĭould we become over-reliant on monitoring devices that make us appear fitter than we actually are? Excessive self-monitoring has been shown to be uncomfortable, intrusive and unpleasant, particularly in people with an existing health condition and tracking your fitness over longer periods of time may become less appealing with the unavoidable effects of ageing. One example of such a small "disruptive commitment" is the need to charge them on a regular – sometimes daily – basis. These devices often require an additional level of commitment that many people find disagreeable. Surveys suggest that more than one in three users stop wearing their device after six months and half stop using the device within a year. However, like many new year resolutions, such as joining a gym, the novelty of a fitness tracker wears off at an alarming speed even among people who are already healthy. Inactive people probably don't want to be reminded of their idleness on a daily or even hourly basis. What has been well established is that fitness trackers are more likely to be bought by people who are already healthy and simply want to track their progress. Similar interventions involving pedometers in isolation without the support of a healthcare professional show no long-term benefit. A recent study, for example, observed that pedometers were effective in increasing activity levels, but these adults were also provided with regular consultations to discuss their progress. Evidence for their effectiveness often relies on single reports from people describing their experience. These sophisticated wearables can support doctors in diagnosis and follow-up of illnesses, and they offer a huge opportunity in illness prevention by serving as a virtual personal coach,” said Chris Van Hoof, program director of imec’s wearable health program.In research we recently published we found little evidence to suggest that owning a fitness tracker makes you healthier. “Imec and Holst Centre develop ultra-small low-power, high-quality sensors and specialized algorithms that turn data into valuable knowledge, paving the way to next generation wearables that offer medical quality data monitoring in a frictionless way. Imec’s algorithm accurately recognizes activity, measures energy expenditure, heart rate and other physiological data. The light and ultra-small device integrates imec’s proprietary algorithm that retrieves physiological parameters with an exceptionally high level of accuracy. Cloudtag Track, a new wearable fitness tracker, was launched at CES 2016, and combines fitness and health monitoring with design, to pave the way to innovation in fitness wearables as well as in the care, cure and prevention cycle by providing immediate access to accurate medical data and personalized feedback. Cloudtag and imec presented the first results of their collaboration on accurate frictionless wearable health solutions.
