Museum visitors are typically advised to follow trajectories planned by curators. Nevertheless, the diverse locomotion techniques available in Virtual Reality (VR) offer various navigation methods that are unattainable within physical museum spaces. Interestingly, these techniques have rarely been explored within museum settings. Our study aims to investigate appropriate navigation methods in VR museums. We first conducted a study in a virtual reconstruction of a local museum with the following navigation methods: a 2D minimap, a World-in-Miniature (WiM) system, and a WiM map. Our results showed that the WiM map with a point-and-select interaction technique outperformed the other two regarding ease of learning, reduced workload, lessened motion sickness, and greater user preferences. Based on the findings, we improved the WiM map and introduced MagicMap. It builds upon the WiM map and translates the curatorial principles of museum visiting into a hierarchical menu layout. Our further evaluation showed that MagicMap supported prolonged engagement in VR museums, enhanced system usability and overall user experience, and reduced users' perceived workload. Our findings have implications for the future design of navigation systems in VR museums and complex indoor environments.

Integrating artificial intelligence (AI) with wearable technology and the power of augmented reality (AR) holds great potential for enabling real-time task assistance. Through wearable sensors and cameras, it is possible to monitor both the state of the physical world and the biometric status of a human operator, which can allow the AI to offer adaptive assistance tailored to match the user's needs and optimize aid. Developing AI models for such purposes requires training data that not only describes users' cognitive state during tasks but also accounts for their responses to the interactive system during the task. We introduce the Multi-Modal User Modeling for Task Guidance (MUMTG) to support the development of AI models for such purposes. The dataset is created through human-subjects studies with users performing search and assembly procedures with help from virtual instructions provided by either a head-worn AR headset or a monitor screen. The data-collection study uses a game-like scenario to guide participants through six guided tasks that vary in difficulty. Within each group, we manipulated task duration and induced several stress triggers to increase the task cognitive demand for three tasks. The dataset includes physiological data such as electrodermal activity, temperature, heart rate, pupil dilation, and gaze. We also collected subjective self-report ratings regarding task workload and emotional responses after each task. We offer this rich dataset as a valuable resource to facilitate the development of user models for task guidance in highly demanding contexts.

We put forward an augmented reality (AR) system using artificial intelligence (AI) to guide users through real-world procedures. The system uses the cameras of the headset to recognize objects and their positions in real time. It constructs a model to predict: (i) the task being completed, (ii) the step of the task they are on, and (iii) whether they have made any errors. By updating this model in real-time as the user completes the task, the system automatically updates the instructions and cues provided to the user. This system represents a step towards ubiquitous task guidance via AR.

In dissimilar telepresence environments, where spaces differ in size and furniture layouts, researchers have proposed methods to adjust avatar movement to deviate from the user's while still adapting to the physical environment. From this perspective, this poster aims to investigate users' perceptions and preferences toward their adjusted avatars. Especially, we propose an experiment focusing on pose standing and sitting which is the most common pose when talking to others. We describe the system setup and initial results that show how users perceive their avatars when their pose category is changed to avoid physics conflict.

Olfactory disorders can significantly affect a human's quality of life. We sought to investigate whether there are opportunities for assistive technologies to support people with olfactory disorders in day-to-day life. To achieve this goal, we surveyed 70 people with olfactory disorders to understand their behaviors, experiences, technologies used, and challenges with olfaction. We then conducted 10 follow-up interviews to further discuss views on current technology for people with olfactory disorders and the design opportunities for assistive technologies for olfaction from their point of view. Our results illustrated participants' varied views on current technology, behaviors/technologies adopted when presented with particular scenarios, and potential solutions for designing assistive technologies for olfactory disorders. Through these findings, we discuss design considerations for assistive technology for olfaction.

Augmented reality can enhance real-world environments, for people with vision impairments by, for example, enlarging fonts, increasing contrast, or amplifying colors. We explore an optical see-through, wearable augmented-reality prototype that offers a zoom feature and various input modalities for users with vision impairments. The participatory-designed prototype was tested and refined with individuals with low vision, and then evaluated in a preliminary study with eight users from the target audience. Our results indicate strong interest among young people and highlight the potential of augmented-reality devices as visual aids.

Virtual Reality Head-Mounted Displays (VR HMDs) are the main ways for users to immerse in a virtual environment and interact with its virtual objects. The experiences of those around the VR HMD users and their effects on HMD users' experiences have not been well studied. In this work, we invite participants to engage in a cross-reality virtual museum visit. With low, medium, and high degrees of non-HMD user involvement, they could incrementally observe, navigate within, and interact with the virtual museum. Our study provides insights into the design of engaging multiuser VR experiences and cross-reality collaborations.

"Animating Recovery" introduces a VR-based hand rehabilitation system that leverages image-based real-time hand tracking to control animal avatars to assist therapy sessions. This system offers personalized and dynamic finger isolation movement rehabilitation training without specialized equipment, making it accessible to a wide range of users. By mapping hand joint movements to avatar animations, the system provides a novel therapeutic experience, allowing for adjustments based on specific hand functions or individual progress. This innovative approach aims to make the rehabilitation process more engaging and effective, particularly for post-stroke recovery.

The current model of development for virtual reality applications is that a single application is responsible for construction of the main immersive experience. If the application is collaborative, that application must implement the required network functionality. We present VRAccomplice an overlay application that adds a collaboration layer to applications running on SteamVR. Using the Ubiq software, we can add avatars controlled by remote users as an overlay into running application. Remote users can see video of the local user. We demonstrate this with some simple examples of a remote user helping a local user in two popular SteamVR games.

We conducted a preliminary study to investigate the impact of the virtual classroom style on cognitive load, spatial awareness, and perceptual responses. We conducted a within-subject study with four different classroom styles. Twenty participants were involved in cognition-demanded tasks while wearing a headset. We found minimal evidence to support that spatial environment design potentially impacts cognitive load and spatial awareness, Based on the findings, our paper discusses the potential of spatial design attributions to enhance learning efficacy in immersive learning experiences.
