Wearable device detects emotions and provides input in real time

A technology that allows wearable sensors to detect and report human emotions: this is how the University of Lancaster, UK, describes the new device developed by researchers from the School of Computing and Communications.

The latter have used “intelligent” materials and have created wrist sensor prototypes which can, in real time, change color, temperature or tighten or vibrate in relation to various user emotions.
According to the same researchers, such a device could be of great help in detecting states such as anxiety, depression and bipolar disorder as well as the whole range related to human emotions.

The device is made with thermochromic materials that can change color when they are heated and therefore when the body temperature increases. During experiments, devices, for example, were activated when users performed movements, worked, played, conversed or relaxed. In fact, the sensor is able to detect changes related to excitation through the galvanic response of the skin, substantially its electrical conductivity.

The device will be presented in more detail at the DIS 2019 conference in San Diego. In any case, it is not a brand new technology to interpret human emotions and states through the skin but this device, according to Muhammad Umair, one of the authors of the research, is not only wearable and also provides non-visual signals but can also vibrate , provide a sense of tension or a feeling of warmth and therefore provides data in real time, rather than historical, allowing the wearer to pay attention to his emotional responses in real time and to understand which moods change and what causes this change.
