Researchers at Cornell University have developed a new app that measures the alert by measuring the size of the student, captured by a burst of pictures taken every time users unlock their smartphones.
The level of alertness of an employee varies during a day's work, sometimes resulting in a decrease in our energy and a wandering spirit just when we have to perform important tasks.
Vincent Tseng, an information science specialist, quotes the Science Daily website: "Since our vigilance varies, if we can find a model, it will be very useful to manage and plan our day," reported the newspaper. 39, German news agency.
"Since people use their phones very frequently during the day, we thought we could use the phone as an instrument to understand and measure their vigilance," said Tseng.
When people are alert, the sympathetic nervous system causes dilation of the pupils to facilitate the collection of information. When they are sleepy, the parasympathetic nervous system causes contraction of the pupils.
Mr. Tseng said that AlertnessScanner could be particularly useful in the health sector, as health professionals often work long hours in complex and important work. For example, doctors and surgeons spend long hours performing tasks that require a high degree of accuracy and concentration. Any mistake can therefore have serious consequences on the lives of patients, noting that a front camera on the devices could monitor their vigilance throughout the procedures.
Tseng said that understanding vigilance patterns could be helpful to people working in many types of workplaces, adding that "it would be good to know the best time to take a break in order to allow your alertness or your energy to regain strength ".
