Transcript of Usability and Accessibility of the "E-Learning Cafe" Platform
Analysis of the "e-learning café“ platform
• To test the accessibility of the site the following technologies were used:– morse code reader; – head mouse; – touch screen; – eye movement reader; – head pointer;
• The usability was evaluated performing:– user tests;

• Morse code reader– the menu options are too close and have a narrow
selection area:• very difficult to select the options in the menu bars;• it requiers to much precision from the user;

• Touch screen (these devices may be used to promote the e-learning café platform)– the menu bars are too narrow:
• difficult to select if the user has wide fingers or has low precision on touch;
• Head pointer– the site doesn’t have good navigation keyboard
shortcuts:• the options aren’t fully explored;• it’s impossible to reach every option and information with the
keybord shortcuts;

• Head Mouse– it’s impossible to do execute "drag and drop“
operations with this device:• the site has many options with this function;
– in order to read the vertical menu, the user has to turn his head to the right:
• involuntarily, the mouse will also flow to the right;
– the site proved to be very complicated to navigate with this tool:
• causes physical disconfort to the user;
Analysis of the "e-learning café“ platform
• The user tests revealed some flaws in usability standards:– there are menus where the mouse arrow turns into a
handler (common indicator of a link) but when you click the option, it doesn´t lead you to a new page, it performs simply a actionscript behavior;
– in the forum option, the user has to fill out a form in case he wants to leave a message, if any errors occur during the validation, all the information the user had previously given will disapear;
