• Constructing Sonified Haptic Line Graphs for the Blind Student: First Steps

  Rameshsharma Ramloll, Wai Yu, Stephen Brewster, Beate Riedel, Mike Burton, Gisela Dimigen · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This paper presents early research from the University of Glasgow's MultiVis project, a three-year initiative investigating how different sensory modalities can make statistical information representations accessible to blind people. The focus is on making line graphs — a…

• Tactile Imaging Using Watershed-Based Image Segmentation

  Sergio E. Hernandez, Kenneth E. Barner · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This paper from the University of Delaware proposes a new image segmentation method for automatically converting visual images into tactile representations suitable for display on tactile devices such as microcapsule (swell) paper. The core problem addressed is that existing…

• Wearable Interfaces for Orientation and Wayfinding

  David A. Ross, Bruce B. Blasch · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This paper from the Atlanta VA Rehabilitation R&D Center presents the development and evaluation of three wearable orientation interfaces designed to help people with severe visual impairment maintain spatial orientation while navigating, with street crossing as the critical…

• Annotation-Based Transcoding for Nonvisual Web Access

  Chieko Asakawa, Hironobu Takagi · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This companion paper to the same authors' transcoding proxy paper (also at Assets '00) provides a detailed technical description of the annotation-based component of their IBM Japan transcoding system. The core problem addressed is that modern web pages are designed with visual…

• A Study of Blind Drawing Practice: Creating Graphical Information Without the Visual Channel

  Hesham M. Kamel, James A. Landay · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This paper from UC Berkeley investigates how blind users create drawings and proposes a grid-based model for non-visual drawing tools. The researchers began by observing that existing drawing tools for blind users fail because they lack adequate contextual feedback — blind users…
