A User Centered Design and Prototype of a Mobile Reading Device for the Visually Impaired

A voice user interface (VUI) was developed that improves the ability of a blind user of a mobile reading device to interact with written material. The image processing techniques required to facilitate this interaction with a document image was also developed.

Contributions of this research include a model of the VUI, which was validated by user tests of a prototype with visually impaired participants, a document image perspective correction technique, a document image dewarping technique, and a headline identification technique, among others.

This resulted in a dissertation: Keefer, R. (2011). A User Centered Design and Prototype of a Mobile Reading Device for the Visually Impaired. Unpublished dissertation Wright State University, Dayton, OH.
