The AT-node for Access database began data from the 39 articles in our systematic review of research on access interfaces, published in Assistive Technology. It has been updated once with 3 additional articles in 2018, with plans to update it annually, using the same search criteria.
We searched 10 databases and included studies in which: typing speed was reported in words per minute or equivalent; the access interface was available for public use; and individuals with physical impairments were in the study population. We used only the text entry rates reported for individuals with physical impairments; studies also had to report the sample size, and the average and standard deviation for the text entry rate data.
Full details on the inclusion criteria and conduct of the systematic review can be found in the Assistive Technology manuscript. To see the original 39 studies in a spreadsheet form, visit our public data sheet.
We'll continue to add to the database over time as new research is published. Additionally, we may include unpublished data in the future, e.g., measurements taken by a practitioner during a computer access assessment, as a supplement to published studies. If you have suggestions about data that should be included, please contact us.
