Abstract
A number of virtual environments have been developed during the last years. Among them there are some environments for blind people based on different type of audio, from simple sounds to 3D audio. In this study we pursued a different approach. We designed AudioMUD by using spoken text to describe the environment, navigation, and interaction. We have also introduced some collaborative aspects into the interaction between blind users. The core of a MUD game is a networked textual virtual environment and with this concept in mind, we developed AudioMUD by adding some collaborative aspects to the basic idea MUD and locating this virtual environment inside the human body. This study presents the design and usability evaluation of AudioMUD. Blind learners were motivated when interacted with AudioMUD and helped to improve the interaction through audio and interface design elements
