A cisco education tool accessible to the vision impaired

Abstract

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.

Designing the next generation of virtual learning environments — Virtual laboratory with remote access to real telecommunication devices

“…This type of education and content delivery systems are applicable for many engineering subjects. Every VL is based on software products, like simulators, emulators, demonstration tools and systems for remote access to real equipment [4,5]. In this way, these types of education platforms are providing not only access to theoretical materials and lectures, but are also enabling remote hand-on access to technology and devices.…”

“…These platforms are also solving some of the "remote access to devices" issues of the elearning and are allowing the educators to develop new learning materials and demonstration products, which can provide new perspectives of the taught materials and specialized systems for the students. Many of the virtual labs in the engineering education are realized using remote Internet access to the real devices [5,6].…”

Advanced IT Education for the Vision Impaired via e-Learning

“…A command line interface to devices provided control and feedback over the simulation. The interface acted in a similar way to the operating system for that device type, for example, a generic DOS-like system for PCs and Cisco IOS for routers (Hope, von Konsky, Murray, Chew, & Farrugia, 2006). iNetSim was designed to be operated solely with the keyboard, alleviating the eye and hand issues faced by vision-impaired students.…”

Remote Laboratory Access for Students with Vision Impairment

“…iNetSim is a accessible network simulator, created to allow both vision-impaired and sighted users to complete CCNA 2 laboratory sessions without access to the networking hardware [2]. Existing software used in the CCNA course for network simulation and laboratory practice (Packet Tracer) and the eLabs is not accessible to those with impaired vision as it utilises images of network topology, allows only mouse selection of network devices and tools and is incompatible with screen reading software.…”
