Hyve-3D and the 3D Cursor: Architectural co-design with freedom in Virtual Reality

Abstract

IntroductionThe mouse, based on the two-dimensional (2D) x-y coordinate system, was adopted as the standard input model for graphical interaction. Planar and pen/tablet-based interactions and multi-touch interfaces, which are similarly 2D, are commonly used by three-dimensional (3D) design software. These models of interaction increase the complexity of the Graphical User Interface (GUI) and make it difficult to design and interact within the 3D space. Also, they only provide a window of the 3D content, making impossible for the user to master spatial configuration and proportions. Although Virtual Reality (VR) seems to be a solution to this AbstractHybrid Virtual Environment 3D (Hyve-3D) is a system that allows architectural co-design inside Virtual Reality by a new model of interaction through a 3D cursor. It augments the concept of the cursor to better interact with threedimensional virtual spaces, rethinking it as a drawing/control plane and viewpoints inside the virtual world. Handheld tablets intuitively manipulate 3D cursors. Users can simultaneously access their individual complementary views on the tablets as personal windows into the shared immersive display. They can concurrently sketch in three dimensions, transform, and manipulate three-dimensional objects using the tablets as tangible props and collectively navigate the scene using the tablet as a 3D trackpad. The system implementation and co-design assessments of different settings are presented.

Developing an Integrated VR Infrastructure in Architectural Design Education

“…For many years, researchers, who are dedicated to finding out how digital instruments can improve architecture education, have made significant contributions to the current willingness for architecture education being viable online. Studies include the impact of VR and digital instruments in design creativity (Alvarado and Maver, 1999 ; Oxman, 2008 ; Celani, 2012 ; Shih et al, 2017 ; Coppens et al, 2018 ), design representation (Indraprastha and Shinozaki, 2009 ; Pelosi, 2010 ; Felbrich et al, 2018 ) and design communication (Dorta et al, 2016a , b ; Schnabel et al, 2016 ). The recent research aggregate interest in examining student-centered and user-oriented approaches through qualitative (Kreutzberg, 2014 ; Gül and Kilimci, 2017 ) and quantitative methods (Wang et al, 2019 ).…”

Breaking the Screen: Interaction Across Touchscreen Boundaries in Virtual Reality for Mobile Knowledge Workers

“…For example, outside of VR, Müller et al [75] investigated the use of touch and mid-air interaction on public displays, Hilliges et al [46] studied tabletop settings. Several researchers have proposed to use handheld touchscreens in spatial user interfaces for tasks such as sketching, ideation and modeling (e.g., [3,23,25,33,48,91]), navigation of volumetric data [106], 3D data exploration [65] and system control [10]. Spatial manipulation has mostly been studied in single-user settings (e.g., [5,51,63,68,74,111,112]) but also in collaborative settings [35].…”

Modélisation Paramétrique en Réalité Virtuelle

“…Plusieurs travaux ont tout de même permis d'amener des capacités d'annotation et d'esquisse dans un contexte VR ; certains de ces travaux visant clairement les pratiques architecturales, comme Hyve-3D (Dorta et al, 2016) qui permet de tracer des traits via un curseur 3D contrôlé par une tablette. Ces travaux amènent donc de l'interaction en immersion, typiquement durant la phase conceptuelle d'un projet.…”
