TL;DR: An assistive suitcase system for supporting blind people when walking through crowded environments using pre-emptive sound notifications, BBeep, and it is observed that the proposed system significantly reduces the number of imminent collisions.
Journal ArticleDOI
Flavonoids as modulators of memory and learning: molecular interactions resulting in behavioural effects.
TL;DR: Current evidence suggests that human translation of these animal investigations are warranted, as are further studies, to better understand the precise cause-and-effect relationship between flavonoid intake and cognitive outputs.
Proceedings ArticleDOI
CaBot: Designing and Evaluating an Autonomous Navigation Robot for Blind People
TL;DR: The design of CaBot (Carry-on roBot), an autonomous suitcase-shaped navigation robot that is able to guide blind users to a destination while avoiding obstacles on their path is presented.
Proceedings ArticleDOI
Virtual Navigation for Blind People: Building Sequential Representations of the Real-World
TL;DR: Two smartphone-based virtual navigation interfaces are presented: VirtualLeap, which allows the user to jump through a sequence of street intersection labels, turn-by-turn instructions and POIs along the route; and VirtualWalk, which simulates variable speed step-by -step walking using audio effects, whilst conveying similar route information.
Proceedings ArticleDOI
Airport Accessibility and Navigation Assistance for People with Visual Impairments
TL;DR: This study presents the first systematic evaluation posing BLE technology as a strong approach to increase the independence of visually impaired people in airports and finds that despite the challenging environment participants were able to complete their itinerary independently.
