Lecture adaptation for students with visual disabilities using high-resolution photography

Published: 23 October 2006 Publication History

Abstract

Visual content in lectures can be enhanced for use by students with visual disabilities by using high-resolution digital still cameras. This paper presents a system which uses two high-resolution cameras; one to capture multiple sources of visual content and another to monitor the head pose of up to 20 audience members. This capture technique eliminates the need for multiple cameras or intrusive and distracting instrumentation but introduced some new problems which were solved with an algorithm used to distinguish between two possible sources of visual interest.
