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 -
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 -
Recognition and Localisation of Pointing Gestures Using a RGB-D Camera
(2020)Communications in Computer and Information Science ~ HCI International 2020 – Posters 22nd International Conference, HCII 2020, Copenhagen, Denmark, July 19–24, 2020, Proceedings, Part INon-verbal communication is part of our regular conversation, and multiple gestures are used to exchange information. Among those gestures, pointing is the most important one. If such gestures cannot be perceived by other team members, e.g. by blind and visually impaired people (BVIP), they lack important information and can hardly participate in a lively work ow. Thus, this paper describes a system for detecting such pointing gestures ...Conference Paper -
Effect of Sense of Embodiment on Curvature Redirected Walking Thresholds
(2020)SAP '20: ACM Symposium on Applied Perception 2020Redirected walking (RDW) allows users to explore a virtual Environment larger than the physical tracking space by real walking. When RDWis applied within certain thresholds, users do not notice it and remain immersed in the virtual environment. There are many factors that affect these thresholds such as walking speed, gender, and field of view. However, redirected walking thresholds (RDTs) were never studied when an avatar is present, and ...Conference Paper
