  @inproceedings{10.1145/3544549.3585726, abstract = {As social virtual reality (VR) becomes more popular, avatars are being designed with realistic behaviors incorporating non-verbal cues like eye contact. However, perceiving eye contact during a conversation can be challenging for people with visual impairments. VR presents an opportunity to display eye contact cues in alternative ways, making them perceivable for people with visual impairments. We performed an exploratory study to gain initial insights on designing eye contact cues for people with visual impairments, including a focus group for a deeper understanding of the topic. We implemented eye contact cues via visual, auditory, and tactile sensory modalities in VR and tested these approaches with eleven participants with visual impairments and collected qualitative feedback. The results show that visual cues indicating the gaze direction were preferred, but auditory and tactile cues were also prevalent as they do not superimpose additional visual information.}, address = {New York, NY, USA}, articleno = {313}, author = {Wieland, Markus and Sedlmair, Michael and Machulla, Tonja-Katrin}, booktitle = {Extended Abstracts of the 2023 CHI Conference on Human Factors in Computing Systems}, doi = {10.1145/3544549.3585726}, isbn = {9781450394222}, location = {Hamburg, Germany}, numpages = {6}, publisher = {Association for Computing Machinery}, series = {CHI EA '23}, title = {VR, Gaze, and Visual Impairment: An Exploratory Study of the Perception of Eye Contact across Different Sensory Modalities for People with Visual Impairments in Virtual Reality}, url = {https://doi.org/10.1145/3544549.3585726}, year = 2023 }

  @inproceedings{10.1007/978-3-031-08648-9_34, abstract = {With the emergence of mainstream virtual reality (VR) platforms for social interactions, non-verbal communicative cues are increasingly being transmitted into the virtual environment. Since VR is primarily a visual medium, accessible VR solutions are required for people with visual impairments (PVI). However, existing propositions do not take into account social interactions, and therefore PVI are excluded from this type of experience. To address this issue, we conducted semi-structured interviews with eleven participants, seven of whom were PVI and four of whom were partners or close friends without visual impairments, to explore how non-verbal cues and joint attention are used and perceived in everyday social situations and conversations. Our goal was to provide guidelines for inclusive conversations in virtual environments for PVI. Our findings suggest that gaze, head direction, head movements, and facial expressions are important for both groups in conversations but often difficult to identify visually for PVI. From our findings, we provide concrete suggestions for the design of social VR spaces, inclusive to PVI.}, address = {Cham}, author = {Wieland, Markus and Thevin, Lauren and Schmidt, Albrecht and Machulla, Tonja}, booktitle = {Computers Helping People with Special Needs}, editor = {Miesenberger, Klaus and Kouroupetroglou, Georgios and Mavrou, Katerina and Manduchi, Roberto and Covarrubias Rodriguez, Mario and Pen{\'a}z, Petr}, isbn = {978-3-031-08648-9}, pages = {295--304}, publisher = {Springer International Publishing}, title = {Non-verbal Communication and Joint Attention Between People with and Without Visual Impairments: Deriving Guidelines for Inclusive Conversations in Virtual Realities}, year = 2022 }

  @inproceedings{Bejan2018, abstract = {As dementia will most likely become an impactful challenge for our future society, it is imperative to maintain the well-being of the diverse group of people with dementia (PwD). Thus, appropriate interventions that effectively trigger identity-stabilizing memories, and at the same time encourage sensorimotor activities, have to be designed and implemented. To that end, we present a novel natural user interface (NUI) system combined with a reminiscence-provoking virtual 3D environment (VE). With it, PwD can delve into memories while interacting with the VE over dementia-fitted gestures. The results of the preliminary evaluations are promising, as they show that most PwD get immersed and cheerfully engage in gesture interactions after a short settling-in period.}, address = {New York, NY, USA}, author = {Bejan, Alexander and Wieland, Markus and Murko, Patrizia and Kunze, Christophe}, booktitle = {Proceedings of the 2018 ACM Conference Companion Publication on Designing Interactive Systems}, day = 30, doi = {10.1145/3197391.3205440}, isbn = {9781450356312}, location = {Hong Kong, China}, month = {05}, pages = {225–230}, publisher = {Association for Computing Machinery}, series = {DIS '18 Companion}, title = {A Virtual Environment Gesture Interaction System for People with Dementia}, url = {https://doi.org/10.1145/3197391.3205440}, year = 2018 }
