• Usability of a Multimodal Video Game to Improve Navigation Skills for Blind Children

  Jaime Sánchez, Mauricio Saenz, Jose Miguel Garrido · 2010 · ACM Transactions on Accessible Computing

  This paper presents an evaluative study of a multimodal system combining a custom haptic device (Digital Clock Carpet) with a 3D audio-based video game (MOVA3D) to develop orientation and mobility (O&M) skills in blind school-aged children. The Digital Clock Carpet is a low-cost…

• Orienting Kinesthetically: A Haptic Handheld Wayfinder for People with Visual Impairments

  Tomohiro Amemiya, Hisashi Sugiyama · 2010 · ACM Transactions on Accessible Computing

  This paper presents a novel haptic direction indicator that provides real-time navigational guidance through kinesthetic cues rather than audio or vibrotactile feedback. The device exploits a perceptual phenomenon called the "pseudo-attraction force technique": by generating…

• Autonomous Navigation through the City for the Blind

  Jaime Sánchez, Natalia de la Torre · 2010 · Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This paper presents a study on the use of an audio-based GPS navigation application designed to help blind people navigate independently through urban environments. The software, developed for PocketPC devices with Bluetooth GPS receivers, uses a clock metaphor to communicate…
