International audience; The field of Virtual Reality has been developing at a steady pace, and VR is finding new uses as a support for creative tasks. The objective of this study is to propose a theoretical model describing the links between user experience and creativity. Pre-existing theoretical links have been identified in relevant scientific literature. Two experiments were then conducted in order to identify new links and replicate results. These experiments involved respectively 76 and 42 participants who individually performed a task requiring divergent creativity using virtual reality drawing tools. The results indicate that cybersickness leads to a decrease in fluency, i.e. the number of ideas generated, but also shades the links between flow and the relevance of the ideas generated. On the basis of this result, we propose the CRUX model to lead to recommendations for the design of tools and simulations to support divergent creativity.

Social experiences that use handheld mobile Augmented Reality with 6DOF tracking can potentially recreate the dynamics of in-person meetings, while still being more accessible than HMD based solutions. We describe a design space of possible avatars for such a platform along the dimensions of body part visibility and the type of movement. We propose a study that aims to measure the effect of five avatar types on social presence during group collaboration.

Mobile Augmented Reality applications have become increasingly popular, however the possible interactions with AR content are largely limited to on-screen gestures and spatial movement. There has been a renewed interest in designing interaction methods for mobile AR that go beyond the screen. Mobile phones present a rich range of input, output, and tracking capabilities, and have been used as controllers for Virtual Reality and head-mounted Augmented Reality applications. In this project, we explore the use of a second phone as a controller for Mobile AR. We developed ARTWO, an application that showcases Handheld Dual Phone AR through a series of small demos in which a second phone can be used to perform basic tasks such as pointing, selecting, and drawing, in the context of real use cases. We believe that the Dual Phone AR approach can help address many of the issues faced when using conventional mobile AR interactions, and also serves as a stepping stone to the general use of phones with head-mounted AR systems in the near future.

International audience; Many studies have shown that physical activity, especially walking, tends to stimulate certain cognitive functions, including divergent creativity. The objective of this study was to understand whether some of this gain comes from the perception of movement, and not merely physical activity itself. 32 participants carried out divergent and convergent creativity tasks in a virtual reality environment consisting of a train inside a tunnel, while wearing a HeadMounted-Display (HMD). For half of the participants, the virtual train was running, and they could therefore see tunnel lamps passing by through the windows. For the other half, the train was stationary. The results of this study indicate that participants perform better at tasks that require divergent creativity when the virtual environment is moving than when it is at a standstill. These results lead to recommendations for the design of tools and environments for meetings and creativity workshops.

In this paper, a new approach towards P. Polycephalum inspired computational efforts is proposed, with specific application to the problem of Multimodal transportation network design for planned cities of the future. Working with a multi-agent model of the Physarum Polycephalum, parallels are drawn between agent properties and mode characteristics, and agents are allowed to dynamically change from one mode to another. A mechanism to compare the performance of resultant multimodal networks against single mode networks involving the same component modes is demonstrated. The observations point to the potential applicability of the new approach in city planning and design.
