Mobile and Collaborative Augmented Reality: A Scenario Based Design Approach

Abstract

Abstract. In this paper we address the combination of the physical and digital worlds in the context of a mobile collaborative activity. Our work seeks to accommodate the needs of professional users by joining their physical and digital operational worlds in a seamless way. Our application domain is archaeological prospecting. We present our approach of the design process, based on field studies and on the design of scenarios of actual and expected activities. We then describe the conceived and developed interaction techniques via the MAGIC platform.

Understanding the everyday use of head-worn computers

“…For the survey, we did quantitative data analysis by calculating acceptance rates and performing Mann-Whitney-U tests for significance tests 10 . In order to evaluate the interview data, we started with a single-case analysis and broke the data down into AEIOU categories.…”

“…touch gestures while running can become difficult and could be improved by speech input or other ways of interaction). Hence, we can conclude that we should design for the device and the current context 10 The investigation of the interaction techniques showed that touch gestures were most frequently used, while speech is most desired. Indeed, we found that one of the key benefits of the device is hands-free interaction.…”

Generic Interaction Techniques for Mobile Collaborative Mixed Systems

“…In [7] we present a scenario-based design approach for mobile collaborative mixed systems. In particular scenarios enable the description of how the system would affect the way mobile users carry out their individual and collective activities.…”

“…In [7] we fully describe the four types of interaction. We focus here on the interaction techniques corresponding to the types (1) and (2).…”

“…The design of the MAGIC system is based on a study of the tasks of archaeological fieldwork, interviews and observations in Alexandria (Egypt) [7]. The archaeological fieldwork in Alexandria is time-constrained because the archaeological site must be explored in less than three months (rescue archaeology).…”
