It turns out that the Japanese company Sony has patented a rather unusual technology, according to which smartphones could automatically take selfie of the owner during the day. The essence of the development is that, based on continuously taken selfies, the software platform would analyze the photo material, dividing it into sad and joyful pictures, and then identify factors that cause strong emotions. The technology should allow to accurately predict the emotional state of the user, promptly offering content that causes positive emotions. The system works as follows: the smartphone takes selfies, sends it to the cloud storage, where information is processed. There, the pictures are divided into joyful and sad, while photos with inexpressive emotions will be deleted. Apparently, the photographs will indeed be created continuously, even shooting during sleep is described. It is argued that, together with related events or consumed content, the platform will learn to predict the emotional state of the user depending on future events, location and downloaded applications and sites. True, there are some doubts about the implementation of the project. The mentioned application is dated Christmas Eve 2013, when the selfie craze was still gaining momentum. However, a lot of time has passed since then, and nothing like this has appeared in Sony devices. The implementation of the idea is likely to be hindered by legal issues related to confidentiality.
