A virtual embodiment can benefit conversational agents, but it is unclear how their personalities and non-verbal behavior influence the User Experience and Social Presence in Augmented Reality (AR). We asked 30 users to converse with a virtual assistant who gives recommendations about city activities. The participants interacted with two different personalities: Sammy, a cheerful blue mouse, and Olive, a serious green human-like agent. Each was presented with two body languages - happy/friendly and annoyed/unfriendly. We conclude how agent representation and humor affect User Experience aspects, and that body language is significant in the evaluation and perception of the AR agent.

A third-person perspective in virtual reality (VR) based public speaking training enables trainees to observe themselves through self-avatars, potentially enhancing their public speaking skills. This study investigates the influence of perspective on the training effects, specifically changes in public speaking skills through training. In the experiment, VR job interview training was conducted for five days under three perspective conditions. Mock interviews were also performed before and after training, and were assessed by external raters. The results revealed that the training effects were significantly higher in the Front condition concerning verbal communication skills and the overall impression of the interview.

Controller-free augmented reality devices currently rely on gesture interaction, which can cause arm fatigue and limit hand mobility. This paper proposes a multimodal interaction technique that combines gaze and pressure ring worn on the index finger. The proposed technique eliminates the need for direct hand capturing using the camera, allowing for more flexible hand movements and reducing fatigue. The experiment conducted in this study demonstrates the effectiveness of the pressure ring in enhancing interaction efficiency.

With ongoing advancements in virtual reality and gamification, researchers have started exploring their application in sign language learning, aiming at enhancing communication between hearing individuals and the deaf community. This study compares the impact of 2D and 3D games on American Sign Language (ASL) learning, using questionnaires to assess user experience. Results show that 3D games enhance engagement, attractiveness, usability, and efficiency, although user performance remains similar in both environments. The findings suggest the potential of 3D game-based approaches to improve ASL learning experiences while also identifying areas for enhancing their dependability and clarity.

Participatory, human-centered, equitable, neurodiverse, and inclusive XR : Co-design of extended reality with autistic users

引用

EDUCATIONAL TECHNOLOGY & SOCIETY 2024年第4期27卷 283-301页

作者： Schmidt, Matthew Lu, Jie Huang, Rui Francois, Marc-Sonley Lee, Minyoung Wang, Xiaoman Feijoo-Garcia, Pedro Guillermo Univ Georgia Dept Workforce Educ & Instruct Technol Athens GA 30602 USA Univ Florida Sch Teaching & Learning Gainesville FL USA Georgia Inst Technol Sch Comp Instruct Atlanta GA USA

Extended reality (XR) such as Virtual Reality (VR) and Augmented Reality (AR) has been heralded as a particularly promising technology for autistic people. However, prior studies have centered around curing or ameliorating deficits and impairments and are typically conducted by non-disabled and non-autistic researchers. Using co-design and a variety of learning experience design methods and processes, Project PHoENIX (Participatory, human-centered, Equitable, Neurodiverse, and Inclusive XR) speaks to the need for research that applies a social-ecological perspective to the design and evaluation of VR experiences for autistic users, with the goal of decreasing environmental barriers and promoting a more inclusive society. In this study, we describe a multi-cycle process of educational design research (EDR), consisting of iterative human-centered formative design, development, implementation, and evaluation of Project PHoENIX from Spring 2021 to Spring 2022. A framework for conducting co-design and collaborative educational design research with autistic individuals in a VR environment is provided along with design principles that support this framework. Findings from 3 meso-cycles illustrate the dual outcomes of educational design research, namely, (1) a consistently maturing intervention and (2) improving theoretical understanding. Findings underscore the feasibility of our approach, and demonstrate potential to scale.

Omni-Directional Treadmills (ODT) and Redirected Walking (RDW) seem suitable for eliciting presence through a full-body walking experience, however both present unique mechanisms that can affect users' presence, comfort, and overall preference. To measure this effect, we conducted a counterbalanced within-subjects user study with 20 participants. Participants wore a wireless VR headset and experienced a tour of a virtual art museum, once using RDW and another time using a passive, slip-based ODT. Both solutions elicit similar amounts of presence, however RDW is perceived as more natural and is the preferred choice of the participants.

Virtual reality (VR) aims to replicate the sensation of a genuine experience through the integration of realism, presence, and embodiment. In this study, we used mobile electroencephalography to quantify differences in anterior cingulate brain activity, an area involved in error monitoring, with and without VR during a challenging balance task to discern the factors contributing to VR's perceptual shortcomings. We found a major delay in the anterior cingulate response to self-generated loss of balance in VR compared to the real world (reflecting less effective detection of balance loss). We also found a very strong response in the anterior cingulate when loss of balance was generated by an external physical disturbance. These findings contribute to our comprehension of the constraints associated with VR in replicating real-world experiences.

This paper introduces our plan to develop a 3D pipeline engineering tool, building upon our in-house web-based Pipeline Reliability and Integrity Management Engineering tool (PRIME), to address the limitations of traditional 2D data visualization in pipeline management. Leveraging immersive technologies, such as Virtual Reality (VR), the tool enhances simulation capabilities, introducing features like multi-user communication, digital twin integration, and virtual site visits. The study proposed in the paper aims to evaluate the tool's potential by comparing it to the existing web application, focusing on immersive training, collaboration tools, 3D data visualization, and environmental conditions in the pipeline maintenance workflows. This research aspires to contribute to the field of immersive technologies in pipeline operations, offering a comprehensive understanding of their impact on efficiency and impactful decision-making.

Visual search tasks are commonplace in daily life. In cases where the time and accuracy of the search is critical (such as first responder, crisis, or military scenarios) augmented reality (AR) visual cueing is potentially beneficial. Three cue conditions (3D Arrow, 2D Wedge, and Gaze Lines) were tested in a visual search task against a baseline no cue condition. Results show that any cue is better than none, however the Gaze Line design produced the lowest search time and greatest accuracy.

We propose an algorithm that extracts the most suitable affordances, interaction targets, and corresponding coordinates adaptively from 3D models of various artifacts based on their functional context for efficient authoring of XR content with artifacts. Traditionally, authoring AR scenes to convey artifact context required one-to-one manual work. Our approach leverages a Large Language Model (LLM) to extract interaction types, positions, and subjects based on the artifact's name and usage context. This enables templated XR experience creation, replacing repetitive manual labor. Consequently, our system streamlines the XR authoring process, making it more efficient and scalable.
