The Drawing and Perception of Architectural Spaces through Immersive Virtual Reality

Abstract

The technologies that have sought to intervene in the architectural drawing process have focused on the sense of sight, leaving aside the use of the hands and the entire body that together achieve more sensory designs. Nowadays, to the benefit of the draftsman, that ideal scenery in which sight, hands and body work holistically is returning thanks to Immersive Virtual Reality (IVR). The purpose of this research is to analyze the perception of two-dimensionally drawn spaces, the drawing of such spaces through three-dimensional sketches in IVR, and both the perception of 3D sketched spaces and those which are also modeled realistically in IVR. First and fifth year architecture students went through the four phases of the experiment: (a) the perception of a space based on 2D sketches, (b) real-scale 3D space drawing in IVR, (c) the perception of a space drawn in 3D in IVR, and (d) the perception of the same space realistically modeled in 3D in IVR. Through three questionnaires and a grading sheet, the data was obtained. The perception of two-dimensionally drawn spaces was high (70.8%), while the precision of a space drawn in an IVR was even higher (83.9%). The real or natural scale in which the spaces can be experienced in an IVR is the characteristic that was most recognized by the students; however, this and the other qualities did not allow for a reliable conclusion for a homogeneous perception of sensations within the virtual spaces.

Virtual reality and traditional design methods in Egyptian context

“…The level of imagination of how the urban space looks increased in the VR method; this may be due to the high level of immersion the VR headsets gives to the participants. Regarding the questions that measure the user's sense of the place, the estimation of the approximate measurements was more accurate in the traditional method than the VR method, in line with Gomez et al (2021) [31]. This can affirm that the traditional method was more precise than the VR method or was affected by the limited functions of the VR headset used in this study.…”

“…He affirms that the only questions that show no difference between the two methods are; the ground slope changes, main location entrance, different species of the tree, location of water features, and benches [30]. Another study sustains that estimating the approximate measurements of the elements expressed by the traditional methods was more accurate than the VR method [31].…”

Application of Virtual Reality Technology in the Restoration of Architectural Decoration Space

“…In the VR scene design of construction accidents, the accident cause theory and trajectory intersection theory guide the design of event process elements, making it more scientific, rigorous, hierarchical, and focused [13]. At the same time, the design of the elements of the accident process should meet the requirements of the drama structure principle for the display of each structure, reasonably arrange the cause events, make the whole scene more authentic and ornamental, not force the accident process, and not rigidly bring the accident results.…”

Perceived Sensations in Architectural Spaces through Immersive Virtual Reality

“…Immersive Virtual Reality, through the visual dimension of perception, in combination with the feedback of interactivity, can be useful to generate immersion, understood as the feeling of being present, even while one maintains a conscious awareness that it is only a digital model (Hermund et al, 2017). This condition coupled with a virtual environment provides a direct link between human perception and the environments we create making each person perceive their environment in a unique way, subconsciously overlaying their surroundings with information to create not just a literal space, but a "perceptual space" of their own (Holth & Schnabel, 2017) Immersive Virtual Reality environments using high resolution Head Mounted Displays (HMD) and haptic controls can generate the aforementioned with full-scale spaces (Gómez-Tone et al, 2021) also due to the precision in the representation of materiality which together with the control tools for navigation in the environment confer a greater sense of presence to simulate architectural experiences and obtain a sensory perception of spaces in real time (Angulo, 2013). Such sensations are so intense that they can generate emotional responses with physiological changes (Roberts et al, 2019) that are serving as indicators to measure human emotional experiences in architectural spaces (Shemesh et al, 2017, Ergan et al, 2019.…”
