Abstract

Two Dimensional Audio Environment for the Visually Impaired, hereinafter TDAEVI is an audio based computer interface with positional information. It provides layout and tabular structures in application interfaces. A prototype system is implemented in order to test the concept. Both qualitative and quantitative evaluations were carried out with users who have an average level of computer skills. Finally the results were analyzed using statistical methods. Position identification of the home page and feedback taken for the questionnaire provided exceptionally positive results towards the concept.
