CONTEXT OF USE, SCENARIO & TASK

It has been three months since Farhani arrived to Vancouver. As usual Farhani wakes up in the morning, gets dressed, and eat breakfast that has been made by his sister Kelia before she goes to work. Farhani is basically by himself all day until his sister returns from work around 7pm. Farhani is reluctant to explore the neighbor because he feels out of place. He feels he is the only person in the whole neighborhood who could not see. Moreover, he has not gain familiarity of the neighbor. Thus, he would only walk up to the end of his street if he needed some fresh air. Throughout the day, Farhani would read English novels using his screen reader and listen to the news station. Since Farhani does not know anyone else in Vancouver, his sister is the only one he would interact with.

One day, he heard from the radio that an African festival will be held this Saturday near Waterfront. Farhani is excited but disappointed at the same time because he has no clue how to attend the event. He told Kelia about his disappointment and his frustration towards this new living style. He mentioned to her that back in Africa, he was very involved in a lot of events. Kelia promised to look for more information on how to get Farhani more involved in the community.

Kelia was introduced to the CNIB website after talking to several of her co-workers. Apparently, the CNIB website is a volunteer agency and charitable organization dedicated to assisting Canadians who are blind or living with vision loss, and to provide information about vision health for all Canadians. Kelia gave the link to Farhani to look at while she is at work. Using screen reader, Farhani enters the CNIB site. However, Farhani feels very lost because the webpage has a lot of information. He did not know where to start nor where to go. Due to frustration of the complexity of the site layout, Farhani only spent 10 minutes on the site before turning his computer off.
