What is facial emotion detection

Review: World Usability Day in Würzburg 2019

In 2019, two important topics dominated our social life, namely sustainability and the future of this earth. With this year's motto "Designing for the Future we want", World Usability Day (WUD) hits the nail on the head. Because what happens and is created today can have a lasting impact on us in our future. That is why many interested students and scientists met and business representatives to explore together how to make the world a better place with influential development.

Well over 200 participants attended the World Usability Day in Würzburg this year, which took place in the Felix Fechenbach House in the Grombühl district. In addition to many interesting lecture topics, there were also two workshops this year. A workshop was held by jo'sbüro, the design sponsor of WUD 2019, and dealt with the user centered design process. The second workshop "Prototyping the Future" was offered by Mayflower, our silver sponsor.

The WUD in Würzburg was opened and moderated by Prof. Dr. Carolin Wienrich, holder of the Human-Technology-Systems chair at the Institute for Human-Computer-Media at the University of Würzburg. After a brief introduction by Tilmann Bock to the gold sponsor Simplifier, the first article about "Digital Companionship and Social User Experience" started. In this, Prof. Carolin Wienrich and Dr. Astrid Carolus on the interaction between people and their technical devices such as smartphones or smart speakers. It was discussed which psychological processes take place when we interact with technical devices and how these affect our relationship with them. In addition, the resulting consequences for the design of technical devices were shown. Because people develop a social bond with their devices, this aspect must now also be taken into account in familiar concepts such as the user experience.

The next lecture "Usability and Web Technology in Industry" was given by Christian Rudolph from HMI Project. Using a practical example, he explained how the user-centered design method in special machine construction can be used to design the most innovative and modifiable user interface possible. Because there, too, user conditions must be examined and taken into account in the design of software solutions. Because with labels like "Fettpresse" or "Winkelwolf" for buttons not everyone can do something straight away

Prof. Dr. In his lecture "Tactile assistance system for the discrete, non-verbal and user-independent determination of facial emotions in everyday life", Nicholas Müller reported to the audience about the communication situation for people with a visual impairment. During face-to-face communication, a lot of information is passed on through gestures and facial expressions. Furthermore, these visual channels are used to compare what is spoken with the facial emotions of the communication partner. The problem that arises here for visually impaired people is that the comparison with what they have spoken cannot take place, since the communication partner does not give any auditory feedback in these situations. This gives rise to a scientific question of how to replace this visual feedback channel. In a prototype test of a tactile assistance system for facial emotion recognition, a mobile phone camera was attached to the shirt pocket, encoding the individual emotions using facial action coding and transmitting them to the user using a vibration element on the non-dominant hand. This enables the visually impaired person to compare their speaking part with an emotional feedback channel.

During the break that followed, visitors could buy food and drinks from the buffet. The break could also be used to discuss the lectures with speakers. The time was used for networking at the stands of the sponsors and partners (Simplifier, ERT, ZDI, German UPA and others).

In the following lecture "The way to a lively UI / UX StyleGuide" Daniel Lenhart and his colleague Axel Pfeuffer demonstrated the development of a uniform StyleGuide for the web-based products of eResearch Technology (ERT). He discussed when a standardized StyleGuide makes sense for a company and what its advantages and disadvantages are. With a StyleGuide he would like to offer coordinated solutions as well as give clear recommendations and guidelines. Because a StyleGuide can help to save a lot of costs, especially in the future, as the necessary adjustments are minimal.

"Hours of boredom, minutes of thrill, moments of terror" is how Dr.med describes. Oliver Happel works in the simulation center of the clinic and polyclinic for anesthesiology at the University Hospital Würzburg. In emergency medicine, patient safety has the highest priority, which is why the design of user interfaces is all the more safety-relevant here. In his lecture "I didn’t know why I was suffering, before I met UX", Dr. Happel draw the audience's attention to the fact that the functions of medical devices are often misinterpreted in everyday clinical practice and that this can have a major impact on the work situation and safety. He would like to encourage usability and UX experts to immerse themselves in the actual work situation of medical professionals for the future work: "Let us cooperate to design for the future we want!".

The World Usability Day in Würzburg was rounded off with a panel discussion in which the audience could ask the speakers questions that were still open. The various lectures from science and business made it clear that usability and UX are becoming increasingly important in product development and can help us to improve user interfaces and designs in the future as well. The World Usability Day in Würzburg was organized by the Department of Psychological Ergonomics at the University of Würzburg, special thanks go to Stephan Huber.
