The main purpose of the task is to check whether we can rely on the accuracy of
measurements conducted using smartwatches and whether we can use them for
medical purposes. During the task, I was testing three different smartwatches,
where the main difference was in the price class to which they belong. As the
cheaper smartwatch I have selected Forever ForeVigo 2 SW-310, as the representative
of the middle price class Huawei GT FTN-B19 and as the representative
of the upper price class Apple Watch Series 6.
During the task I used different measurement devices as a reference according
to the measured parameter. I was checking the accuracy of measured parameters
such as heartbeat, calorie burn, travelled distance and blood oxygen saturation.
The measurements were conducted via non-invasive measurement methods which
I further divided into measurements during movement and measurements while
being still. I conducted 10 measurements in movement and 30 measurements
while being still for each of the three watches, in addition to a series of 30 measurements
for blood oxygen saturation with the Apple watch.
We could gather from the conducted measurements that the price class has
its effect on the measurement quality, because the best-performing watch was of
the upper price class (Apple watch). In addition, we could also conclude that
smartwatches can give us solid accuracy of measuring medical parameters such
as heartbeat and blood oxygen saturation.
