Towards mobile multi-display environments : a design exploration using projection-screen devices

Thanks to miniaturization of display technologies, the recent years have seen the emergence of a new generation of mobile devices containing multiple displays. They are identified as Mobile Multi-Display Environments (MMDEs), building on previous work in the field of Multi-Display Environments. This doctoral work presents the first exploration and classification of this research space. In particular, I identify the case of projection-screen MMDEs, mobile devices containing both projection and screen technologies. The dissertation address the following thesis: Providing re-configurability of displays' relative placements in the heterogeneous MMDE and providing interaction using kinaesthetic cues and spatial memory, users can manage complex and highly cognitively charged tasks as well as complex information management across multiple displays. To support this thesis, the dissertation answers research questions around the possibility of synchronous use of the displays given their inherent technological and physical disparities; the optimal relative positioning of the displays; the use of the mobile-projection unit as a secondary display and the projection spaces available around the user. The contributions of this work are multiple, the main contributions are: case studies evaluating and demonstrating the usefulness of synchronous use of the multiple displays; design guidelines for MMDEs; novel interaction techniques and scenario of use; a mathematical model of perceived depth in the mobile environment; and a series of prototypes and experiments that have been designed to support this work. The dissertation shows that multiple displays can be used synchronously to improve the device's capabilities in heterogeneous projection-screen MMDEs so users can perform complex tasks across both displays. This dissertation's vision is that mobile devices with multiple displays can become as useful and as widespread as their fixed MDEs. The results presented in this dissertation further the knowledge of MMDEs.
