- A game as a tool for empirical research on the shamanic interface conceptPublication . Pinto, Tiago Susano; Coelho, António; Lukosch, Stephan; Morgado, LeonelA Shamanic Interface is a recent concept that posits that the acknowledgment of culture in gestural commands may contribute to richer and more powerful user interaction with abstract concepts and complexity, but has a lack of empirical validation. Hence, this paper presents a game developed as an empirical research tool for data collection and testing on shamanic interfaces. The game is a small maze where users use gestures to control a character to reach the end of each level. The control gestures performed by each user are captured with a Leap Motion controller and recognized through Hidden Markov Models. Three command sets were implemented: Portuguese cultural gestures, Dutch cultural gestures, and a generic set. This paper evaluates the game with different users to check its playability. We conclude that the game can be used as a research data-collection tool as is, but also acknowledge several playability-related improvement recommendations.
- Immersive learning experiences for understanding complex systemsPublication . Fernandes, Luís; Morgado, Leonel; Paredes, Hugo; Coelho, António; Richter, JonathonComplexity is core part of our lives. Aware or not, people need to understand and communicate complex ideas and perspectives. Understanding and communicating complexity can be facilitated through interactive simulations. Doing so in the physical world is often impractical, however. Users and developers are overloaded with information and ambiguity, costs are prohibitive, and unsupervised physical simulations raise safety concerns. Novel immersive technology might hold the key to transforming how we tackle understanding and communicating complexity. In this position paper, we propose empowering user agency and perception to take part in complex learning experiences and create their own, combining two factors: enhanced visual and spatial context provided by location-awareness, immersive environments, and somatic, embodied agency; and enhanced cultural and social context by leveraging as input methods the rich semantics of cultural-social gestures and rituals. To deem the feasibility of this argument, we propose developing two culture-aware prototypes, one for the Confederated Salish and Kootenai Tribes in Montana, United States, and another for a Western Europe cultural context.
