Accessible spaces: navigating through a marked environment with a camera phone
This short Assets '07 demonstration paper from UC Santa Cruz and the Smith-Kettlewell Eye Research Institute describes a camera-phone-based wayfinding system for blind travellers. The core idea is to deploy small, cheap, pie-shaped colour markers in …

Usability of a multimodal videogame to improve navigation skills for blind children
This paper presents a usability evaluation of two complementary tools designed to help blind school-aged children develop orientation and mobility (O&M) skills in closed, unfamiliar spaces. The first tool is the Digital Clock Carpet (DCC), a custom-b…

Haptic Handheld Wayfinder with Pseudo-Attraction Force for Pedestrians with Visual Impairments
This paper presents a compact handheld haptic device that guides visually impaired pedestrians by generating a directional force sensation — a feeling of being pulled or pushed toward the correct direction. The device exploits a perceptual phenomenon…

Autonomous Navigation through the City for the Blind
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 clo…
