Modern smartphones collect a lot of information about their owners. It has long been known that various companies receive information (as they claim, impersonally) to improve the algorithms of their products. However, by the way a person uses a smartphone, one can learn a lot about his character. You do not have to look at the installed applications and even unlock the smartphone. Enough only data received from the device accelerometer.
What is an accelerometer?
Unless technical details are concerned, the accelerometer is a device for measuring the acceleration of an object. An accelerometer is typically a type of sensor that is mounted on one side of an elastic suspension and on the other side has a device for damping vibrations (damper). A deviation of the sensor from its original position provides information about the acceleration force. For smartphones, this feature of the accelerometer is used to automatically rotate the screen, detect knocking or shaking gestures, count the number of steps, etc. In this case, the accelerometer often works even when the smartphone is locked.
The simplest accelerometer. It's probably a bit more complicated in your smartphone, but the basic principle of the work remains the same.
How to determine the character of a person with a smartphone
Not so long ago, scientists at the Royal Melbourne University of Technology said that many of the key parameters for a person's personality and character can be calculated from the smartphone's accelerometer. As the journalists of the Engadget publication noted, the experts took into account the fact that you can use the gadget's accelerometer to find out what distance a person is traveling per day and how fast they are doing. We also looked at how many times a person checks notifications and takes calls.
That's interesting: An unexpected fact about hallucinations is revealed.
The authors found that the indicators they use are directly related to the manifestation of human characteristics. But how? Everything is very simple: according to scientists, sociable people who participated in the experiment usually have impulsive behavior and spend their free time outside the home, but often in different places. And women with increased sensitivity regularly check alerts. Surprisingly, on the contrary, men of the same trait rarely do so.
Why do you need this?
Unfortunately, nothing new here. According to scientists, the new data layer of accelerometers can be used to better select recommended pairs on dating sites, improve social network algorithms, and work more effectively with all of these popular targeted ads. However, it is not worth waiting for the development of new algorithms in the near future. The new study was preliminary and concerned only 52 people. Now, Royal Melbourne University of Technology experts want to reiterate the experience of having a larger sample.
