Work in Progress Report: Nonvisual Visual Programming
Clayton Lewis
Abstract: Visual programming systems are widely used to introduce children and other learners to programming, but they cannot be used by blind people. Inspired by the ideas of blind computer scientist T.V.Raman, the Noodle system provides nonvisual access to a dataflow programming system, a popular model for visual programming systems. This paper describes the design and implementation of Noodle and some of its capabilities. The paper suggests that the same approach used to develop Noodle could be applied to increase the accessibility of other visual programming systems for learners with disabilities.
