Let's look at an ordinary day with the eyes of a blind person. There is so much to take for granted which is not given to others, for example, because they can't see. What happens with people who are totally blind? All of a sudden, many things are done very differently. Sometimes, accessible technologies will solve the problem. This includes any technology which can be used equally well by those who can see and those who can't. In other cases, special technologies need to be used to achieve the same that others do just by using their sight. This is technology which is specifically developed for blind people.
Let's follow a blind person through a whole work day. For the sake of the example, we will call her Lisa.
We will examine how technology helps Lisa throughout her whole day. We will not discuss anything else, but instances, where information technology can help her. We won't look at any other issues she might be facing. There are many more challenges we could talk about, but in order to overcome those, information technology itself will not solve the problem. In this post, I will only demonstrate how much information technology can make a difference.
