Emotional Design and User Study on Guidance System For MR Distributed Collaboration

In recent years, especially after the outbreak of COVID-19, the applications of distributed collaboration in mixed reality (MR) environment has developed rapidly. Due to the cutting-edge technology and the specialized nature of the equipment, many studies have focused on the design of tutorials in MR, but few studies have taken the factors of emotional design into consideration. Since the perception of the state among users is based on their avatar firstly, which is helpful for users' perceptions about collaborative content in novice guidance. Based on Norman's principles of reflective design and James' theory about the experience self, we built a MR virtual sand-table collaboration system, which contains three guiding parts that are the full practice of theoretical research. Furthermore, We generated three progressive levels of emotional solutions in guidance design and conducted user experience research to explore the impact of three different degrees of emotional design, summarizing the applicable paradigm of novice guidance of emotional design in MR distributed collaborative scenarios. Through the evaluation and analysis of SUS model and task load, we found that novice guidance with a higher emotional design level, which combines static graphics, dynamic hand models and conversational voice would result in a better user experience.
