From Narrative to Numbers: Evaluating Survey Questionnaires with Large Language Models

As the field of intelligent interfaces is evolving, there is also a growing need for feedback mechanisms that are both expressive for participants and also contain reliable and useful information for the researcher conducting the study for survey data collection. Our study involves exploring two different kinds of sur…

Effects of Virtual Reality System Fidelity on Presence using the Fidelity-based Presence Scale

Numerous studies have investigated the effects of system fidelity as a whole on one’s total sense of presence in virtual reality (VR). The Fidelity-based Presence Scale (FPS), a recently introduced presence questionnaire, provides a method for investigating the effects of different system fidelities (interaction, scen…

From One World to Another: Interfaces for Efficiently Transitioning Between Virtual Environments

Personal computers and handheld devices provide keyboard shortcuts and swipe gestures to enable users to efficiently switch between applications, whereas today's virtual reality (VR) systems do not. In this work, we present an exploratory study on user interface aspects to support efficient switching between worlds in…

Mitigating Response Delays in Free-Form Conversations with LLM-powered Intelligent Virtual Agents

We investigated the challenges of mitigating response delays in free-form conversations with virtual agents powered by Large Language Models (LLMs) within Virtual Reality (VR). For this, we used conversational fillers, such as gestures and verbal cues, to bridge delays between user input and system responses and evalu…

Using Co-Design with Streamers and Viewers to Identify Values and Resolve Tensions in the Design of Interpersonal Wearable Telepresence Systems

We conducted a co-design study with 26 users in dyadic groups who were assigned to the opposing roles of ``Streamers'' and ``Viewers'' to design interactive, wearable telepresence prototypes for interpersonal use. The goal was to elicit values, identify value tensions, and resolve these tensions in the design of a sys…

Unlocking Understanding: An Investigation of Multimodal Communication in Virtual Reality Collaboration

Communication in collaboration, especially synchronous, remote communication, is crucial to the success of task-specific goals. Insufficient or excessive forms of communication may lead to detrimental effects on task performance while increasing mental fatigue. However, identifying which combinations of communication…

Automatic Improper Loading Posture Detection and Correction Utilizing Electrical Muscle Stimulation

Chronic lower back pain due to improper lifting techniques poses a major workplace safety hazard. The major risk factors for improper loading posture (ILP) include overloading, and improper loading of the lumbar muscles, ligaments, and vertebrae due to repetitive mechanical stresses exerted upon them. The current inte…

Effective 2D Stroke-based Gesture Augmentation for RNNs

Recurrent neural networks (RNN) require large training datasets from which they learn new class models. This limitation prohibits their use in custom gesture applications where only one or two end user samples are given per gesture class. One common way to enhance sparse datasets is to use data augmentation to synthes…

Effects of Field of View on Egocentric Distance Perception in Virtual Reality

We performed a mixed-design study with 56 participants to compare the effect of horizontal FOV (HFOV) and vertical FOV (VFOV) on egocentric distance perception in four different realistic virtual environments (VEs). We also compared VE attributes of indoor/outdoor and cluttered/uncluttered. The participants blind-walk…

The Voight-Kampff Machine for Automatic Custom Gesture Rejection Threshold Selection

Gesture recognition systems using nearest neighbor pattern matching are able to distinguish gesture from non-gesture actions by rejecting input whose recognition scores are poor. However, in the context of gesture customization, where training data is sparse, learning a tight rejection threshold that maximizes accurac…

Distance Perception with a Video See-Through Head-Mounted Display

In recent years, pass-through cameras have resurfaced as inclusions for virtual reality (VR) hardware. With modern cameras that now have increased resolution and frame rate, Video See-Through (VST) Head-Mounted Displays (HMD) can be used to provide an Augmented Reality (AR) experience. However, because users see the…
