“…In this case we want to enable users of the prototypes (either at a desktop or at a CAVE) to interact with them via their own portable devices (e.g. [18]) increasing the ease of use and facilitate the interaction with the simulation.…”

Ubiquitous computing poses new usability challenges that cut across design and development. We are particularly interested in "spaces" enhanced with sensors, public displays and personal devices. How can prototypes be used to explore the user's mobility and interaction, both explicitly and implicitly, to access services within these environments? Because of the potential cost of development and design failure, the characteristics of such systems must be explored using early versions of the system that could disrupt if used in the target environment. Being able to evaluate these systems early in the process is crucial to their successful development. This paper reports on an effort to develop a framework for the rapid prototyping and analysis of ambient intelligence systems.

“…One well known technique is motion capturing: the performer's motions are mapped onto a virtual character. In most cases, a 1:1 mapping is used to achieve realistic Jacobson [12] Monkey [8] Eitsuka [7] Osawa [25] One-take Laszlo [18] Motion Doodles [33] Komura [15] Zhiqiang [21] Numaguchi [23] Kim [14] Krause [17] Mobile Animator [10] Shin [28] Creature…”

Figure 1: With Creature Teacher users can quickly create organic movements by successively selecting and manipulating parts of a virtual creature. (a) The user is wearing an HMD and pinch gloves. (b) Body parts are selected using the left hand. (c) Selected parts are manipulated using the right hand. (d) Periodic movements are detected and played back repeatedly. ABSTRACTWe present Creature Teacher, a performance-based animation system for creating cyclic movements. Users directly manipulate body parts of a virtual character by using their hands. Creature Teacher's generic approach makes it possible to animate rigged 3D models with nearly arbitrary topology (e.g., non-humanoid) without requiring specialized user-to-character mappings or predefined movements. We use a bimanual interaction paradigm, allowing users to select parts of the model with one hand and manipulate them with the other hand. Cyclic movements of body parts during manipulation are detected and repeatedly played back -also while animating other body parts. Our approach of taking cyclic movements as an input makes mode switching between recording and playback obsolete and allows for fast and seamless creation of animations. We show that novice users with no animation background were able to create expressive cyclic animations for initially static virtual 3D creatures.

“…In VRML 3D geometric objects, their shape, the appearance of the shape and their behaviour or transformations, that can be applied, are described in nodes arranged in scene graphs. A mobile VRML browser and development kit, Pocket Cortona (2009) An interface for editing and manipulating virtual characters on mobile devices is tested on the 'mobile animator' interface (Gutiérrez et al, 2004) which adapts the intuitive graphical interaction of professional, commercial desktop 3D packages, like Maya (2009) or 3ds Max (2009, using virtual manipulators. 3D objects and camera are directly controllable on the handheld display by selecting and dragging body parts with a stylus.…”

Performing plays or creating films and animations is a complex creative, and thus expensive, process involving various professionals and media. This research project proposes to augment this process by automatically interpreting film and play scripts and automatically generating animated scenes from them. For this purpose a web based software prototype, SceneMaker, will be developed. During the generation of the story content, special attention will be given to emotional aspects and their reflection in the execution of all types of modalities: fluency and manner of actions and behaviour, body language, facial expressions, speech, voice pitch, scene composition, timing, lighting, music and camera. The main objective of this work is to demonstrate how a scene and actor behaviour changes, when emotional states are taken into account, e.g. walking down a street in a happy versus a sad state. Consequently, more realistic and believable story visualisations are an expected outcome. Literature on related research areas is reviewed involving natural language and text, screenplay or play script, layout processing with regard to personality and emotion detection, modelling affective behaviour of embodied agents, visualisation of 3D scenes with digital cinematography and genre-based presentation, intelligent multimedia selection and mobile 3D technology.SceneMaker's architecture with a language and text analysis module, a reasoning and decision making module based on cognitive, emotional information and a multimedia module for multimodal visualisation are presented along with a development plan and test scenarios. Technologies and software relevant for the development of SceneMaker are analysed and prospective tools for text and language processing, visualisation, media allocation and mobile user interfaces are suggested. Accuracy of content animation, effectiveness of expression and usability of the interface will be evaluated in empirical tests. In relation to other work, this project will present a genre-specific text-to-animation methodology which combines all relevant expressive modalities. Emotional expressivity inspired by the OCC (Ortony, Clore and Collins) emotion model will influence all modalities to enhance believability of virtual actors as well as scene presentation. Compared to other scene production systems, SceneMaker will infer emotions from the story context, rather than relying on explicit emotion keywords, SceneMaker will automatically detect genre from the script and apply appropriate cinematic direction. Also SceneMaker will enable 3D animation editing via web-based and mobile platforms.In conclusion, SceneMaker will reduce production time, save costs and enhance communication of ideas through the development of an intelligent, multimodal animation generation system providing quick previsualisations of scenes from script text input.
