The smartphone is not not. The accuracy of these devices becomes increasingly important as the medical experts are rushing to harness them as a tool of data collection.
The extreme diffusion of this object to global in theory enables an average person to participate in various studies and the scientists to collect information. But the tool is improved.
A new study from the University of British Columbia, published in the Journal of Sports Medicine, reveals that the pedometer built into the iPhone, although the most reliable smartphones in this area, has failed about 1 340 not during the typical day of a user.

The technology is not fully to blame. Many of the participants in the study were reported to have left the phones behind them during short trips home (to the bathroom, the kitchen…) or in the office. And daily life often involves speeds of walking slower, which, according to the laboratory test, can affect the accuracy of the accelerometer which is placed in the phone.
“The accelerometer of the iPhone does a very good job when it is tested in laboratory conditions “, admits the lead author Guy Faulkner. “You just have to have it on you all the time. “
The results suggest that researchers should exercise caution when relying on data from smartphones of different brands and qualities variables.

“If a phone indicates that 10,000 steps were walked in the day, its owner must know that he will have done at least as much “, reassures one of the authors. “From the point of view of public health, it is better to underestimate than overestimate “.
