“…The most common approach has been integrating handheld and touchscreen devices into virtual environments for 2D interaction [26][27][28][29][30]. Others have focused on providing hybrid input, such as the Virtual Tricoder [31], Pinch Glove-based 2D/3D cursor approach [32], Pick and Drop approach [33], and other tangible user interfaces [34].…”

This paper presents a novel 2D/3D desktop virtual reality hybrid user interface for radiology that focuses on improving 3D manipulation required in some diagnostic tasks. An evaluation of our system revealed that our hybrid interface is more efficient for novice users and more accurate for both novice and experienced users when compared to traditional 2D only interfaces. This is a significant finding because it indicates, as the techniques mature, that hybrid interfaces can provide significant benefit to image evaluation. Our hybrid system combines a zSpace stereoscopic display with 2D displays, and mouse and keyboard input. It allows the use of 2D and 3D components interchangeably, or simultaneously. The system was evaluated against a 2D only interface with a user study that involved performing a scoliosis diagnosis task. There were two user groups: medical students and radiology residents. We found improvements in completion time for medical students, and in accuracy for both groups. In particular, the accuracy of medical students improved to match that of the residents.

“…However, VR is better defined in terms of human experience as a ‘real or simulated environment in which a perceiver experiences telepresence or mediated perception of an environment’ (Steuer 1995). In this sense, a VR system is characterized in terms of its capabilities of immersion (perception of an artificial world), interaction with the environment, and presence or feeling of physically being in the environment (Wloka 1995). This concept makes VR an entire science centered in the human being and allows professionals from other fields of knowledge – such as psychology, computer science, and engineering design – to build new research areas upon the capabilities of VR systems to explore human perception.…”

This research presents a pilot study that explores the use of quantified Gestalt principles of symmetry, parallelism, and continuity as design variables to evaluate the aesthetics of three-dimensional product representations. To this end, a virtual reality (VR)-based discrete choice experiment was conducted to elicit subjects’ preferences among pairs of bottle forms with diverse Gestalt values. While immersed in the VR environment, 42 participants were able to visually explore the whole forms, thus capturing more information to develop their judgment. Further analysis of the choice data using standard and mixed logit regression with hierarchical Bayes estimation provides initial details on the aesthetic utility of the Gestalt principles in question, their distribution among the sample participants, and the correlation between estimates. Due to the small sample size, the results are not expansible and they only apply to the data set gathered during the experiment. Nevertheless, it is an initial proof of concept which could suggest that symmetry and continuity have a positive aesthetic effect over people, and that parallelism could have opposite aesthetic utilities for women and men. This methodology allows designers to delve into the integration of aesthetics as a quantifiable property in the product development process.
