About AT-node

AT-node for Access is a public, searchable collection of research on the use of computer access interfaces by people with disabilities. The name comes from the acronym for Assistive Technology Network of Outcomes, Data, and Evidence.

The Access database focuses on data from access interfaces used to control a computer or augmentative communication system. It includes text entry rate data from studies published since 1986. A registry option exists for those who wish to add new data to the database.

AT-node arose out of a systematic review on access interfaces for people with disabilities, written by Heidi Horstmann Koester and Sajay Arthanat.1 The goal is to make the hard-won data from the systematic review available to others, and to provide a way to continually maintain a current database of valid data on access interfaces.
