Eyes on Many: Evaluating Gaze, Hand, and Voice for Multi-Object Selection in Extended Reality

Interacting with multiple objects simultaneously makes us fast. A pre-step to this interaction is to select the objects, i.e., multi-object selection, which is enabled through two steps: (1) toggling multi-selection mode --- mode-switching --- and then (2) selecting all the intended objects --- subselection. In extend…

Improving the Steering Law Throughput Calculation by Defining Effective Parameters for 3D Virtual Environments

Throughput is a widely used performance metric, combining speed and accuracy into a single measure, while reducing the effect of subjective speed–accuracy trade-offs. Despite its wide application in 2D steering tasks, its direct extension to 3D presents unique challenges since 3D trajectories exhibit higher variabilit…

VoiceRay: 3D Object Selection Technique for Occluded and Dense Environments in Virtual Reality

Disambiguating distal target selection in dense and occluded virtual environments has been a challenge for Virtual Reality (VR) interaction design. While raycasting is a widely used interaction technique for selecting distant objects, it defaults to the first intersected target, forcing users into disambiguation phase…

Repurposing Audio Playback Tools to Test Human Localization with 6DoF Sound

Six-degree-of-freedom audio is a growing interest in interactive software, but it does not easily conform to object-based rendering when achieved with arrays of ambisonics microphones. Prior studies rely on subjective metrics also, which do not clearly indicate how this additional audio interaction might aid a human i…

There Is More to Dwell Than Meets the Eye: Toward Better Gaze-Based Text Entry Systems With Multi-Threshold Dwell

Dwell-based text entry seems to peak at 20 words per minute (WPM). Yet, little is known about the factors contributing to this limit, except that it requires extensive training. Thus, we conducted a longitudinal study, broke the overall dwell-based selection time into six different components, and identified several d…

A Systematic Review of Fitts’ Law in 3D Extended Reality

Fitts' law is widely used as an evaluation tool for pointing or selection tasks, evolving into diverse applications, including 3D extended reality (XR) environments like virtual, augmented, and mixed reality. Despite standards like ISO 9241:411, the application of Fitts' law varies significantly across studies, compli…

An Artists' Perspectives on Natural Interactions for Virtual Reality 3D Sketching

Virtual Reality (VR) applications like OpenBrush offer artists access to 3D sketching tools within the digital 3D virtual space. These 3D sketching tools allow users to ``paint'' using virtual digital strokes that emulate real-world mark-making. Yet, users paint these strokes through (unimodal) VR controllers. Given t…

EyeGuide & EyeConGuide: Gaze-based Visual Guides to Improve 3D Sketching Systems

Visual guides help to align strokes and raise accuracy in Virtual Reality (VR) sketching tools. Automatic guides that appear at relevant sketching areas are convenient to have for a seamless sketching with a guide. We explore guides that exploit eye-tracking to render them adaptive to the user's visual attention. Eye…

Better Definition and Calculation of Throughput and Effective Parameters for Steering to Account for Subjective Speed-accuracy Tradeoffs

In Fitts' law studies to investigate pointing, throughput is used to characterize the performance of input devices and users, which is claimed to be independent of task difficulty or the user's subjective speed-accuracy bias. While throughput has been recognized as a useful metric for target-pointing tasks, the corres…

AdaCAD: Parametric Design as a New Form of Notation for Complex Weaving

Woven textiles are increasingly a medium through which HCI is inventing new technologies. Key challenges in integrating woven textiles in HCI include the high level of textile knowledge required to make effective use of the new possibilities they afford and the need for tools that bridge the concerns of textile design…
