Remote Laboratory Access for Students with Vision Impairment

Developing methodologies for the presentation of graphical educational material in a non-visual form for use by people with vision impairment

“…By using this accessible version of Packet Tracer students with vision impairments are able to interact with network simulator in the same way as sighted students. Additionally, it supports teamwork, classroom games, instructor consoles and remote instructor-student and studentstudent interactions that are beneficial for sighted students too [17].…”

“…iNetsim incorporated all features included in Packet Tracer such as network topology design and configuration of network devices [18]. Figure 6 -iNetsim Interface [17] The drag and drop, dialog boxes, and pop up windows in Packet Tracer introduced difficulties for screen reader navigation. To resolve this problem iNetsim stores information in tables, which enables rapid navigation of connections, devices and status for a screen reader application.…”

“…To resolve this problem iNetsim stores information in tables, which enables rapid navigation of connections, devices and status for a screen reader application. By presenting data in table format, all information is available in the main canvas, which makes it easier even for sighted student to search and find material [17]. The usage of mouse is totally replaced by keyboard, helping vision impaired student to use the simulator.…”

The Research and Application of Simulation Learning Tool

“…Packet Tracer presents the network behavior through real-time mode and simulation mode, the Real-Time mode is adopted to build network topologies, which provides the same network behavior as in real situations, the simulation mode is used to simulate processes inside the created topology [5], hence, students can see the control time interval, the internal process of data transmission, the evolution of data across network in simulation mode, the animation of packet is shown in Fig. 2.…”
