• Headlock: A Wearable Navigation Aid that Helps Blind Cane Users Traverse Large Open Spaces

  Alexander Fiannaca, Ilias Apostolopoulous, Eelke Folmer · 2014 · ASSETS '14: Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper presents HEADLOCK, a navigation aid for optical head-mounted displays (OHMDs) like Google Glass that helps blind cane users traverse large open spaces—environments that are particularly challenging because they lack the tactile features (walls, corridors, floor…

• Text-to-Speeches: Evaluating the Perception of Concurrent Speech by Blind People

  João Guerreiro, Daniel Gonçalves · 2014 · ASSETS '14: Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper investigates whether blind people can leverage the Cocktail Party Effect—the human ability to focus on one speech source among several while still detecting relevant content in the background—to more efficiently scan digital information. Screen readers present content…

• From Screen Reading to Aural Glancing: Towards Instant Access to Key Page Sections

  Prathik Gadde, Davide Bolchini · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS 2014)

  This paper addresses a fundamental problem in screen reader navigation: while sighted users can glance at a web page to instantly understand its structure and locate relevant sections, screen reader users are forced to listen to content serially, making navigation of complex…
