Work-in-Progress: Effects of Attention Guidance on Virtual Reality Training for an Industrial Assembly Task
(2023)2023 Proceedings of the 9th International Conference of the Immersive Learning Research Network (iLRN 2023) Posters & Doctoral ColloquiumOne of the main objectives of Virtual Training Environments (VTEs) for industrial training is to train workers for a real world task. Prior work identified a multitude of factors influencing a VTE’s effectiveness. In this work-in-progress paper, we add to this body of research by evaluating the effect of attention guidance (AG) on a VTE’s effectiveness. In a controlled between-subject design pilot study with 42 participants, participants ...Conference Paper -
Eye Gaze Tracking for Detecting Non-verbal Communication in Meeting Environments
(2020)Proceedings of the 15th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and ApplicationsNon-verbal communication in a team meeting is important to understand the essence of the conversation. Among other gestures, eye gaze shows the focus of interest on a common workspace and can also be used for an interpersonal synchronisation. If this non-verbal information is missing and or cannot be perceived by blind and visually impaired people (BVIP), they would lack important information to get fully immersed in the meeting and may ...Conference Paper -
Accessible Multimodal Tool Support for Brainstorming Meetings
(2020)Lecture Notes in Computer Science ~ Computers Helping People with Special Needs, 17th International Conference, ICCHP 2020, Lecco, Italy, September 9–11, 2020, Proceedings, Part IIIn recent years, assistive technology and digital accessibility for blind and visually impaired people (BVIP) has been signi cantly improved. Yet, group discussions, especially in a business context, are still challenging as non-verbal communication (NVC) is often depicted on digital whiteboards, including deictic gestures paired with visual artifacts. However, as NVC heavily relies on the visual perception, which represents a large ...Conference Paper -
Pointing Gesture Based User Interaction of Tool Supported Brainstorming Meetings
(2020)Lecture Notes in Computer Science ~ Computers Helping People with Special Needs, 17th International Conference, ICCHP 2020, Lecco, Italy, September 9–11, 2020, Proceedings, Part IIThis paper presents a brainstorming tool combined with pointing gestures to improve the brainstorming meeting experience for blind and visually impaired people (BVIP). In brainstorming meetings, BVIPs are not able to participate in the conversation as well as sighted users because of the unavailability of supporting tools for understanding the explicit and implicit meaning of the non-verbal communication (NVC). Therefore, the proposed ...Conference Paper -
Accessibility of Non-verbal Communication: Making Spatial Information Accessible to People with Disabilities
(2020)Lecture Notes in Computer Science ~ Computers Helping People with Special Needs, 17th International Conference, ICCHP 2020, Lecco, Italy, September 9–11, 2020, Proceedings, Part IINon-verbal communication (NVC) is challenging to People with disabilities. Depending on their impairment, they are either unable to perceive relational gestures within performed by sighted people, or they are unable to perform gestures by themselves in such an Information space (in case of motoric impairments such as cerebral palsy). Also other 3D gestures such as sign language and other aspects of non-verbal communication could provide ...Conference Paper -
Perception of a Spatial Implausibility Caused by Seamless Covert Teleportation
(2024)Proceedings of the 19th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications - Volume 1: GRAPP, HUCAPP and IVAPPThis paper explores human perception of spatial implausibility using seamless teleportation in circular and hexagonal closed-loop corridors. The impression of impossibility is generated by subtle teleporting the user within these corridors, thereby allowing them to unconsciously skip certain sections of them. Different levels of this ``impossibility’’ are presented by varying the percentage of skipping within these corridors, specifically ...Conference Paper -
The Chaotic Behavior of Redirection – Revisiting Simulations in Redirected Walking
(2022)2022 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)Redirected Walking (RDW) is a common technique leveraged to allow real walking for exploring large virtual environments in constrained physical tracking spaces. Effective RDW is challenging due to its complexity and disturbance factors (e.g., spontaneous user behavior). Existing techniques range from combinations of simple motion scaling to more elaborate curvature injections and reactive, predictive, or scripted steering concepts. However, ...Conference Paper -
Emotion Recognition - A Tool to Improve Meeting Experience for Visually Impaired
(2022)Lecture Notes in Computer Science ~ Computers Helping People with Special NeedsFacial expressions play an important role in human communication since they enrich spoken information and help convey additional sentiments e.g. mood. Among others, they non-verbally express a partner’s agreement or disagreement to spoken information. Further, together with the audio signal, humans can even detect nuances of changes in a person’s mood. However, facial expressions remain inaccessible to the blind and visually impaired, and ...Conference Paper -
Accessibility of Co-Located Meetings
(2022)Lecture Notes in Computer Science ~ Computers Helping People with Special NeedsNon-verbal communication is an important carrier of information. Even though the spoken word can be heard by blind and visually impaired persons, up to 60% of the overall information still remains inaccessibly to them due to its visual character [11]. However, there is a wide spectrum of non-verbal communication elements, and not all of them are of the same importance. In particular for group meetings, facial expressions and pointing ...Conference Paper -
Designing Virtual Training Environments: Does Immersion increase Task Performance?
(2020)2020 International Conference on Cyberworlds (CW)One of the main characteristic of virtual reality (VR) is immersion, which leads to the creation of sophisticated illusions of reality. Accordingly, VR is already used for a wide spectrum of applications like entertainment, marketing, and training. Especially in training applications, the effect of immersion on training success is still not entirely clear, since too much immersion may cause side effects such as users experiencing high ...Conference Paper
