Typing is still the primary input modality for computing systems. Most typical Virtual Reality (VR) setups replace users' capable hands and fingers with cumbersome hand-held controllers (HC). This study examines the hypothesis that finger interaction and realistic representation of users' hands increases typing performance, sense of Presence, and the usability of a typing system for a text transcription task in VR. We developed a hand and finger tracking and visualization system (VH) aimed to help users interact with on-screen keyboards in VR, and compared participants typing performance using HC. We found that the VH paradigm in VR significantly increased typing performance for inexperienced typists and that HC users were more prone to commit errors. Further research may delve deeper into the utility of VH input paradigm for people unable to grasp HCs and for other symbolic communications such as sign language.

This chapter presents a conceptual framework for an emerging type of user interfaces for mobile ubiquitous computing systems, and focuses in particular on the interaction through motion of people and objects in physical space. We introduce the notion of Kinetic User Interface as a unifying framework and a middleware for the design of pervasive interfaces, in which motion is considered as the primary input modality.

Virtual Reality Exposure

This study is an examination of the effect of computer-generated virtual reality graded exposure on the physiological and psychological responses of performing musicians. Eight university saxophone majors, five men and three women, participated in twelve 15- to 20-minute weekly practice sessions during which they were immersed in one of four different virtual environments designed to elicit various anxiety levels. Baseline heart rates and subjective measurements were taken prior to immersion and continued throughout the exposure period. In addition, heart rate and subjective measurements were recorded for three live performances given by each subject before beginning the virtual reality exposure and after completion of the sixth and the twelfth exposure sessions. Findings indicated that the virtual environments did elicit a sense of presence and may have provided the means for desensitization. Heart-rate readings and psychological indications of anxiety did not always correspond.

AbstractSpatially resolved transcriptomics is an emerging class of high-throughput technologies that enable biologists to systematically investigate the expression of genes along with spatial information. Upon data acquisition, one major hurdle is the subsequent interpretation and visualization of the datasets acquired. To address this challenge, VR-Cardiomicsis presented, which is a novel data visualization system with interactive functionalities designed to help biologists interpret spatially resolved transcriptomic datasets. By implementing the system in two separate immersive environments, fish tank virtual reality (FTVR) and head-mounted display virtual reality (HMD-VR), biologists can interact with the data in novel ways not previously possible, such as visually exploring the gene expression patterns of an organ, and comparing genes based on their 3D expression profiles. Further, a biologist-driven use-case is presented, in which immersive environments facilitate biologists to explore and compare the heart expression profiles of different genes.

The drum-like virtual reality (VR) keyboard is a contemporary, controller-based interface for text input in VR that uses a drum set metaphor. The controllers are used as sticks which, through downward movements, “press” the keys of the virtual keyboard. In this work, a preliminary feasibility study of the drum-like VR keyboard is described, focusing on the text entry rate and accuracy as well as its usability and the user experience it offers. Seventeen participants evaluated the drum-like VR keyboard by having a typing session and completing a usability and a user experience questionnaire. The interface achieved a good usability score, positive experiential feedback around its entertaining and immersive qualities, a satisfying text entry rate (24.61 words-per-minute), as well as moderate-to-high total error rate (7.2%) that can probably be further improved in future studies. The work provides strong indications that the drum-like VR keyboard can be an effective and entertaining way to type in VR.
