When navigating larger virtual environments and computer games, natural walking is often unfeasible. Here, we investigate how alternatives such as joystick- or leaning-based locomotion interfaces ("human joystick") can be enhanced by adding walking-related cues following a sensory substitution approach. Using custom-designed foot haptics system evaluating it in multi-part study, show that related auditory (footstep sounds), visual (simulating bobbing head-motions from walking), vibrotactile...

Many optical-see-through displays have a relatively narrow field of view. However, limited view can constrain how information be presented and searched through. To understand these constraints, we present series experiments that address the interrelationships between view, density, search performance. We do so by simulating various fields using two approaches: limiting on Microsoft HoloLens head-worn display dynamically changing portion large tiled-display wall which is presented, for...

Current augmented reality displays still have a very limited field of view compared to the human vision. In order localize out-of-view objects, researchers predominantly explored visual guidance approaches visualize information in (in-view) screen space. Unfortunately, conflicts like cluttering or occlusion often arise, which can lead search performance issues and decreased awareness about physical environment. this paper, we compare an innovative non-visual approach based on audio-tactile...

In Augmented Reality (AR), search performance for outdoor tasks is an important metric evaluating the success of a large number AR applications. Users must be able to find content quickly, labels and indicators not invasive but still clearly noticeable, user interface should maximize in variety conditions. To address these issues, we have set up series experiments test influence virtual characteristics such as color, size, leader lines on noticeability both real simulated environments. We...

This paper introduces FaceHaptics, a novel haptic display based on robot arm attached to head-mounted virtual reality display. It provides localized, multi-directional and movable cues in the form of wind, warmth, moving single-point touch events water spray dedicated parts face not covered by display.The easily extensible system, however, can principally mount any type compact actuator or object. User study 1 showed that users appreciate directional resolution cues, judge wind direction...

Head-worn devices with a narrow field of view are common commodity for Augmented Reality. However, their limited screen space makes management difficult. Especially in dense information spaces this potentially leads to visual conflicts such as overlapping labels (occlusion) and clutter. In paper, we look into the potential using audio vibrotactile feedback guide search localization. Our results indicate users can be guided high accuracy audio-tactile maximum median deviations only 2° on...

In presence of conflicting or ambiguous visual cues in complex scenes, performing 3D selection and manipulation tasks can be challenging. To improve motor planning coordination, we explore audio-tactile to inform the user about objects hand proximity, e.g., avoid unwanted object penetrations. We do so through a novel glove-based tactile interface, enhanced by audio cues. Through two studies, illustrate that proximity guidance spatial awareness, motions, collision avoidance behaviors, show...

In this article, we report on a user study investigating the effects of multisensory cues triggering emotional response in immersive games. Yet, isolating effect specific sensory cue state is difficult feat. The performed experiment first series that aims at producing usable guidelines can be applied to reproducing similar responses, as well methods measure effects. As such, are interested methodologies both design effective stimuli, and assess quality thereof. We start with identifying main...

Augmented reality applications allow users to enrich their real surroundings with additional digital content. However, due the limited field of view augmented devices, it can sometimes be difficult become aware newly emerging information inside or outside view. Typical visual conflicts like clutter and occlusion augmentations occur further aggravated especially in context dense spaces. In this article, we evaluate how multisensory cue combinations improve awareness for moving out-of-view...

We present a novel forearm-and-glove tactile interface that can enhance 3D interaction by guiding hand motor planning and coordination. In particular, we aim to improve motion pose actions related selection manipulation tasks. Through our user studies, illustrate how patterns guide the user, triggering changes, for example grasp (select) manipulate (move) an object. discuss potential limitations of interface, outline future work.

We present a novel, multilayer interaction approach that enables state transitions between spatially above-screen and 2D on-screen feedback layers. This supports the exploration of haptic features are hard to simulate using rigid screens. accomplish this by adding layer above screen can be actuated interacted with (pressed on) while user interacts content pen input. The provides variable firmness contour feedback, its membrane functionality affords additional tactile cues like texture...

In this research demo, we show different examples for the integration of multisensory cues to enhance user engagement and trigger emotional responses in immersive environments. Our primary focus is use modular-designed system supportive treatment anxiety disorders.

We report on two experiments that deploy low-frequency audio and strong vibrations to induce haptic-like sensations throughout the human body. Vibration is quite frequently deployed in immersive systems, for example provide collision feedback, but its actual effects are not well understood [Kruijff & Pander 2005; Kruijff et al. 2015]. The starting point of our was a study by Rasmussen [Rasmussen 1982], which found different vibration frequencies were experienced differently will show how...

Supported by their large size and high resolution, display walls suit well for different collaboration types. However, in order to foster instead of impede processes, interaction techniques need be carefully designed, taking into regard the possibilities limitations size, effects on human perception performance. In this paper we investigate impact visual distractors (which, instance, might caused other collaborators' input) peripheral vision short-term memory attention. The occur frequently...

The visual and auditory quality of computer-mediated stimuli for virtual extended reality (VR/XR) is rapidly improving. Still, it remains challenging to provide a fully embodied sensation awareness objects surrounding, approaching, or touching us in 3D environment, though can greatly aid task performance user interface. For example, feedback warning signals potential collisions (e.g., bumping into an obstacle while navigating) pinpointing areas where one’s attention should be directed points...

Augmented Reality (AR) applications increasingly rely on eye and head gaze tracking for user interaction, with their efficacy influenced by environmental factors such as spatial arrangements lighting conditions. This paper presents two studies that examine how these variables affect the performance of in AR environments. While partially delivered faster results, its exhibited greater variability, especially under dynamic Conversely, tracking, while providing more consistent showed a notable...
