Computer user emotion detection methods in human computer interaction

Exploring and observing the emotions of a computer user plays an important role in human-computer interaction. It allows us to assess user satisfaction with the product, cognitive load, stress level, and other indicators. Finding out what usability methods are utilised to capture and explore emotions, as well as identify the strengths and weaknesses of these methods. To evaluate the methods of verbal emotion expression and facial expression used in the pilot study. The theoretical method of literature analysis was used, as well as the analysis of verbal emotional expressions and facial expressions used in the pilot study, which allows us to obtain results. Theoretical emotional evaluation of computer users and analysis of observation methods without the application of a pilot study to methodological detection methods of key possibilities, such as facial expressions that can be analyzed by observation and software, skin conductivity or using an electroencephalogram. Based on the evaluation of the methods used in the pilot study, weaknesses were identified that need to be improved. The main methods of emotional evaluation of computer users are the analysis of facial expressions with the help of software, skin conductivity and electroencephalogram, where data is obtained and analyzed not only by qualitative, but also by quantitative methods.
