A cisco education tool accessible to the vision impaired

摘要

This paper describes iNetSim, a universally accessible network simulator, created to allow vision-impaired and sighted users to complete Cisco Certified Network Associate level two (CCNA 2) laboratory sessions. Previously, software used in the CCNA course was not accessible to those with impaired vision because it utilized images of network topology. These images were incompatible with screen reader software. In contrast, iNetSim is assessable by blind and vision impaired users, in addition to those with normal vision. It is based on Mac OS X Tiger, an operating system with an integrated screen reader called VoiceOver.
