“…Many IPW features such as obstacle avoidance and path following may help to decrease accidents that occur during PW use. This notion is in keeping with previous research where participants in a long-term care facility recognized that collision avoidance would help to prevent accidents [23]. Interestingly, participants in another study suggested that an IPW could be used for training purposes for individuals who are having difficulty learning to drive a PW, which may improve skill and decrease accidents [15].…”

Purpose: To explore power wheelchair users', caregivers' and clinicians' perspectives regarding the potential impact of intelligent power wheelchair use on social participation. Methods: Semistructured interviews were conducted with power wheelchair users (n ¼ 12), caregivers (n ¼ 4) and clinicians (n ¼ 12). An illustrative video was used to facilitate discussion. The transcribed interviews were analyzed using thematic analysis. Results: Three main themes were identified based on the experiences of the power wheelchair users, caregivers and clinicians: (1) increased social participation opportunities, (2) changing how social participation is experienced and (3) decreased risk of accidents during social participation. Conclusion: Findings from this study suggest that an intelligent power wheelchair would enhance social participation in a variety of important ways, thereby providing support for continued design and development of this assistive technology.ä Implications for Rehabilitation An intelligent power wheelchair has the potential to:Increase social participation opportunities by overcoming challenges associated with navigating through crowds and small spaces. Change how social participation is experienced through ''normalizing'' social interactions and decreasing the effort required to drive a power wheelchair. Decrease the risk of accidents during social participation by reducing the need for dangerous compensatory strategies and minimizing the impact of the physical environment.

“…We apply similar techniques to the problem of navigation by combining adaptive prompts with collision avoidance to allow wheelchair users to reach their destination in a safe and timely manner. The study reported in this paper advances other studies with older adults with dementia driving anti-collision wheelchairs [11] [12] by adding a wayfinding component.…”

Many older adults with cognitive impairment are excluded from powered wheelchair use because of safety concerns. This leads to reduced mobility, and in turn, higher dependence on caregivers. In this paper, we describe an intelligent wheelchair that uses computer vision and machine learning methods to provide adaptive navigation assistance to users with cognitive impairment. We demonstrate the performance of the system in a user study with the target population. We show that the collision avoidance module of the system successfully decreases the number of collisions for all participants. We also show that the wayfinding module assists users with memory and vision impairments. We share feedback from the users on various aspects of the intelligent wheelchair system. In addition, we provide our own observations and insights on the target population and their use of intelligent wheelchairs. Finally, we suggest directions for future work.

“…Hence, CA technology may provide enhanced opportunities for skills and confidence training. CA technology's potential as an adjunctive training tool for older users has been previously suggested [39]. However, the effectiveness of CA and the recommended protocols to be used in power mobility training with older adults requires further exploration.…”

Abstract-Collision avoidance technology has the capacity to facilitate safer mobility among older power mobility users with physical, sensory, and cognitive impairments, thus enabling independence for more users. Little is known about consumers' perceptions of collision avoidance. This article draws on interviews (29 users, 5 caregivers, and 10 prescribers) to examine views on design and utilization of this technology. Data analysis identified three themes: "useful situations or contexts," "technology design issues and real-life application," and "appropriateness of collision avoidance technology for a variety of users." Findings support ongoing development of collision avoidance for older adult users. The majority of participants supported the technology and felt that it might benefit current users and users with visual impairments, but might be unsuitable for people with significant cognitive impairments. Some participants voiced concerns regarding the risk for injury with power mobility use and some identified situations where collision avoidance might be beneficial (driving backward, avoiding dynamic obstacles, negotiating outdoor barriers, and learning power mobility use). Design issues include the need for context awareness, reliability, and user interface specifications. User desire to maintain driving autonomy supports development of collaboratively controlled systems. This research lays the groundwork for future development by illustrating consumer requirements for this technology.
