User emotional experience connected with web services play an important role. Positive emotions and pleasant experience with a website increase the chance a web-based service to be used by a customer. Negative emotions influenced by a website can decrease business value of the web services on the market. The companies should tackle such issues by looking at web services design through dynamic emotional User Experience (deUX) lens. There is a need of a methodology to support web services design aimed at stimulating positive emotions while using web services. This lecture considers the deUX design of web services. It explains what constitutes the new research area of web services deUX. A methodology for assessing and designing web services oriented to deUX improving is presented. Dimensions of dynamic emotional user experience with web services are defined. A checklist guiding deUX assessment and design is proposed. Relevant quantitative indices for measuring dynamic eUX with web services are developed. This methodology defines guidelines and recommendations for deUX design of web services with the aim to provide points of reference for web designers. The lecture presents a case study of medical web services illustrating the methodology. Research scope is identified. Further research directions are pointed out.
