This paper presents a new platform for interactive concatenative synthesis designed for virtual reality and proposes further applications for immersive audio tools and instruments. TimbreSpace VR is an extension of William Brent’s TimbreSpace software using the timbreID library for Pure Data. Design and implementation of the application are discussed, as well as its live performance aspects. Finally, future work is laid out for the project, proposing versatile audio manipulation software specifically for XR platforms.

Two frameworks are described, within the larger framework of Pure Data, that aim to facilitate the creation and preservation of electronic music that is performed live in real time. These are not part of Pd itself, because they are more directly tailored to a specific application space than Pd should be. They are nonetheless designed, like Pd, to minimize any unnecessary stylistic imposition on creators of electronic music. The Null Piece is a starting point for building live performance patches. It provides basic audio routing and parameter control while leaving other choices as free as possible. Reality Check is an attempt to aid in the long-term maintenance of a musical realization by verifying whether a piece still runs as intended despite the inevitable evolution of hardware and software.

AbstractAccess to systems for robot-assisted surgery is limited due to high costs. To enable widespread use, numerous issues have to be addressed to improve and/or simplify their components. Current systems commonly use universal linkage-based input devices, and only a few applicationoriented and specialized designs are used. A versatile virtual reality controller is proposed as an alternative input device for the control of a seven degree of freedom articulated robotic arm. The real-time capabilities of the setup, replicating a system for robot-assisted teleoperated surgery, are investigated to assess suitability. Image-based assessment showed a considerable system latency of 81.7 ± 27.7 ms. However, due to its versatility, the virtual reality controller is a promising alternative to current input devices for research around medical telemanipulation systems.

Objective. Although simulation-based medical education is fundamental for acquisition and maintenance of knowledge and skills; simulators are often located in urban centers and they are not easily accessible due to cost, time, and geographic constraints. Our objective is to develop a proof-of-concept innovative prototype using virtual reality (VR) technology for clinical tele simulation training to facilitate access and global academic collaborations. Methodology. Our project is a VR-based system using Oculus Quest as a standalone, portable, and wireless head-mounted device, along with a digital platform to deliver immersive clinical simulation sessions. Instructor’s control panel (ICP) application is designed to create VR-clinical scenarios remotely, live-stream sessions, communicate with learners and control VR-clinical training in real-time. Results. The Virtual Clinical Simulation (VCS) system offers realistic clinical training in virtual space that mimics hospital environments. Those VR clinical scenarios are customizable to suit the need, with high-fidelity lifelike characters designed to deliver interactive and immersive learning experience. The real-time connection and live-stream between ICP and VR-training system enables interactive academic learning and facilitates access to tele simulation training. Conclusions. VCS system provides innovative solutions to major challenges associated with conventional simulation training such as access, cost, personnel, and curriculum. VCS facilitates the delivery of academic and interactive clinical training that is similar to real-life settings. Tele-clinical simulation systems like VCS facilitate necessary academic-community partnerships, as well as global education network between resource-rich and low-income countries.
