Developing mobile mixed reality application based on user needs and expectations

Mixed reality refers to the unification and interaction of the digital and physical environments giving an immersive view of the environment to its users. The aim of our study is to investigate the needs and expectations of the potential users of a futuristic and a novel technology called Mobile Mixed Reality (MMR). Based on the users´ impressions and expectations, we developed MMR prototypes representing various scenarios and contexts of use. We observed that the most important factors that play a role when it comes to acceptability are usefulness, personalization, reliability, and relevance. We developed different prototypes that were tested in order to evaluate the prototype acceptability. The understanding provided by the study helped in designing early MMR prototypes. The most intrusive elements that should be supported by any MMR application were found to be usefulness (how useful is the information to any individual), personalization (personify the information with such questions as what, how and when to receive any information), reliability (accuracy and authenticity of the presented information), and relevance (utility and value of the information).
