Almost by default applications are extended with networking capabilities, either deployed locally on the client device and connecting to a server or, as the trend is now, fully hosted on the Internet (servers) as a service (cloud services). However many 3D applications are still restricted to a single platform, as it is costly in terms of developing, maintaining, adapting and providing support for multiple platforms (software as well for hardware dependencies). Therefore applications that we see now available on a variety of devices are either single-platform, single-user, non-real-time collaborative or graphically not demanding. By using an adaptive remote rendering approach it is feasible to take advantage of these new devices and provide means for old and new 3D oriented applications to be used in collaborative environments. In this paper, we look at the conversion of a single user 3D application into a multi-user service. Analyse the requirements needed for adapting the software for being integrated into the \"Herd framework\". Offering remote rendering to end devices, a single instance accessible to multiple users and in order to optimize each instance of the application for different devices the user interface representation is handled in a dynamically using a device profile, as well for handling different input techniques.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

This included full body tracking, vibrotactile feedback and voice. This allowed interactions in the same CVE between multiple people situated in different physical remote locations. This system was used for an experiment to study whether the conveyance of touch has an impact on the willingness of participants embodied in the CVE to sing in public.\u0000 In a first experimental condition, the experimenter virtually touched the avatar of the participants on the shoulder, producing vibrotactile feedback. In another condition using the identical physical setup, the vibrotactile displays were not activated, so that they would not feel the touch. Our hypothesis was that the tactile touch condition would produce a greater likelihood of compliance with the request to sing. In a second part we examined the hypothesis that people might be more willing to sing (execute an embarrassing task) in a CVE, because of the anonymity provided by virtual reality. Hence we carried out a similar study in physical reality.\u0000 The results suggest that the tactile intervention had no effect on the sensations of body ownership, presence or the behaviours of the participants, in spite of the finding that the sensation of touch itself was effectively realised. Moreover we found an overall similarity in responses between the VR and real conditions.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

A human-in-the-loop (interactor) metaphor provides remote control of multiple virtual characters, with support for multiple interactors and multiple observers. Custom animation blending routines and a gesture-based interface provide interactors with an intuitive digital puppetry paradigm. This paradigm reduces the cognitive and physical loads on the interactor while supporting natural bi-directional conversation between a user and the virtual characters or avatar counterparts. A multi-server-client architecture, based on a low-demand network protocol, connects the user environment, interactor station(s) and observer station(s). The associated system affords the delivery of personalized experiences that adapt to the actions and interactions of individual users, while staying true to each virtual character's personality and backstory. This approach has been used to create experiences designed for training, education, rehabilitation, remote presence and other-related applications.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

However in most setups using a BCI, the user is explicitly asked to remain as motionless as possible, since muscular activity is commonly admitted to add noise and artifacts in brain electrical signals. Thus, as for today, people have been rarely let using other classical input devices such as mice or joysticks simultaneously to a BCI-based interaction. In this paper, we present an experimental study on the influence of manipulating an input device such as a standard computer mouse on the performance of a BCI system. We have designed a 2-class BCI which relies on Alpha brainwaves to discriminate between focused versus relaxed mental activities. The study uses a simple virtual environment inspired by the well-known Pac-Man videogame and based on BCI and mouse controls. The control of mental activity enables to eat pellets in a simple 2D virtual maze. Different levels of motor activity achieved with the mouse are progressively introduced in the gameplay: 1) no motor activity (control condition), 2) a semi-automatic motor activity, and 3) a highly-demanding motor activity. As expected the BCI performance was found to slightly decrease in presence of motor activity. However, we found that the BCI could still be successfully used in all conditions, and that relaxed versus focused mental activities could still be significantly discriminated even in presence of a highly-demanding mouse manipulation. These promising results pave the way to future experimental studies with more complex mental and motor activities, but also to novel 3D interaction paradigms that could mix BCI and other input devices for virtual reality and videogame applications.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.
