“…To address this issue some improvements of the simulator can be made. First, as it is indicated in [24], adding auditory cues can increase the perceived self-motion. In future work we will then address this problem by adding sounds to our simulator, especially wheelchair noises.…”

Driving a power wheelchair is a difficult and complex visual-cognitive task. As a result, some people with visual and/or cognitive disabilities cannot access the benefits of a power wheelchair because their impairments prevent them from driving safely. In order to improve their access to mobility, we have previously designed a semi-autonomous assistive wheelchair system which progressively corrects the trajectory as the user manually drives the wheelchair and smoothly avoids obstacles. Developing and testing such systems for wheelchair driving assistance requires a significant amount of material resources and clinician time. With Virtual Reality technology, prototypes can be developed and tested in a risk-free and highly flexible Virtual Environment before equipping and testing a physical prototype. Additionally, users can "virtually" test and train more easily during the development process. In this paper, we introduce a power wheelchair driving simulator allowing the user to navigate with a standard wheelchair in an immersive 3D Virtual Environment. The simulation framework is designed to be flexible so that we can use different control inputs. In order to validate the framework, we first performed tests on the simulator with able-bodied participants during which the user's Quality of Experience (QoE) was assessed through a set of questionnaires. Results show that the simulator is a promising tool for future works as it generates a good sense of presence and requires rather low cognitive effort from users.

“…For people with visual impairments, virtual white canes have been explored (Siu et al, 2020; Zhao et al, 2018). Additionally, for people with mobility impairments, motion platforms for wheelchairs have been studied (Brachtendorf et al, 2020; Richir et al, 2015).…”

Virtual reality (VR) continues to revolutionize how people work, play, and socialize. Even with new VR systems released regularly, VR hardware can still be inaccessible to many, especially people with disabilities. While researching VR accessibility barriers for older adults, we discovered that the Meta Quest 2 VR head-mounted display (HMD) does not allow for a person with a cochlear implant to wear both simultaneously. This inaccessibility is due to the cochlear implant being surgically implanted along the path of the HMD strap. To increase VR accessibility for individuals with a cochlear implant, we designed, developed, and tested a 3D-printed HMD strap modification that supports wearing both a VR HMD and a cochlear implant. This work illustrates that small, simple modifications can significantly increase the accessibility of VR system hardware for people with disabilities.
