One of the features of the new device in that mood he makes no facial expression or tone of a person and more “objective” indicators, such as breathing and heartbeat. Radio waves “reflected” away from the body, allow the instrument to collect this information, and to correctly decode its device helps the particular learning algorithm. As a result, the device with high probability can determine what a person feels at the moment.

The device is able to recognize four different emotions — excitement, anger, sadness and pleasure. Experiments with volunteers showed that the algorithm is able to guess the emotion correctly in 72 percent of cases, when dealing with a stranger and in 87% of cases after “training”.

According to the developers, their offspring can be used in order to monitor the human reaction to a film, thereby allowing the figures of the film industry to get more information about how people have perceived the results of their work. In addition, the device could warn the owner of impending depression. Finally, the device developed by scientists could “fine-tune” the music and the lighting in the room, the mood of those in it.

Read more about his invention, the specialists plan to speak during the conference, MobiCom (International Conference on Mobile Computing and Networking), which will be held in new York from 3 to 7 October.
