Publication Open Access Demonstration of XRStudio tools for creation of room-size immersive experiences within an extended reality environment(ACM, 2023) Ardaiz Villanueva, Óscar; Olaz Moratinos, Xabier; Benbelkheir Núñez, Youssef; Lerga Armendáriz, Álvaro; Gasco González, Lucas; Estadística, Informática y Matemáticas; Estatistika, Informatika eta Matematika; Institute of Smart Cities - ISCImmersive experiences are mostly created with desktop-based tools using flat displays, mouse and keyboard; as a result immersive experiences have a 2D look and interaction: user sit or stand looking forward, and interact with elements within reach of their arms as in a desktop. The objective of this work is to facilitate creating room-size immersive experiences that take advantage of tethered head mounted displays and hand-held controllers to create while walking freely in space with full body movement freedom. To this end we propose XRStudio, a set of tools that permit to create within an extended reality environment so that authors can walk to move objects in space or manipulate elements with hand and full body movements as in the real world.Publication Open Access A virtual reality direct-manipulation tool for posing and animation of digital human bodies: an evaluation of creativity support(MDPI, 2024-07-10) Benbelkheir Núñez, Youssef; Lerga Armendáriz, Álvaro; Ardaiz Villanueva, Óscar; Institute of Smart Cities - ISCCreating body poses and animations is a critical task for digital content creators, movement artists, and sports professionals. Traditional desktop-based tools for generating 3D poses and animations often lack intuitiveness and are challenging to master. Virtual reality (VR) offers a solution through more intuitive direct-manipulation capabilities. We designed and implemented a VR tool that enables direct manipulation of virtual body parts with inverse kinematics. This tool allows users to pose and animate virtual bodies with one- or two-handed manipulations, while also moving, including bending, jumping, or walking. Our user study demonstrated that participants could produce creative poses and animations using this tool, which we evaluated for creativity support across six factors. Additionally, we discuss further opportunities to enhance creativity support.
