BreatHero is a faster-paced Virtual Reality (VR) action game that explores the potential of combining breathing techniques learning with the combat elements of action games. BreatHero uses breathing techniques as various skills for attacking and defending against the enemies, so players can do breathing exercises while enjoying defeating the in-game enemies. We choose three breathing techniques: Kapalabhati, Box Breathing, and Full Yogic Breathing, which are all beneficial for physical and mental health. To enhance breathing techniques learning and memorization in action games, we present two design concepts: Imitative Breathing Feedback and Associate Learning on Breathing Techniques. Results from our study indicated that players found the game to be more engaging and were willing to play it repeatedly, suggesting that breathing exercises can be effectively integrated into faster-paced action games.

The surge in e-commerce and the COVID-19 pandemic has dramatically driven the demand for home appliances. However, this surge has also resulted in a proportional increase in electrical accidents. Furthermore, the current product manual does not provide users with intuitive and timely information. Virtual reality (VR) can deliver effective learning information with its exceptional simulation capabilities and immersive content. Thus, we explored the application of VR to enhance home appliances’ display and user experience for user demand to deliver the manuals on the appliances and promote safe uses. A purposive sampling technique was employed, and 12 target users participated in the in-depth interviews. In the study, the VR application of the home appliance product experience and learning showed positive outcomes. The results can be used as a reference for future design. According to the users’ feedback, we summarized and proposed eight future design directions for enhancing the virtual home appliance experience.
