The client is an Australian not-for-profit organization, which provides services to assist people who are blind or have low vision, assisting them in achieving the possibilities they choose in their life. The client wanted to build a retailer system with facilities that would enable retailers who have limited vision to carry out transactions easily and precisely.
The biggest problem to blind people or people with low vision is that they cannot view the computer screen clearly. Therefore, it would be extremely difficult for them to use the mouse to control and progress the work. Moreover, as they cannot have a precise sense of the working process, they will probably get loss in a complicated system with various steps and functions.
Citigo envisioned that accessibility and convenience would be the two most important features of the system.
For accessibility, the system would comply with international standards for Web accessibility. A screen reading software would be integrated into the system to allow people with limited vision to understand the information appearing on the screen. Besides, shortcut keys would also be fully utilized as a substitute for the mouse. In order for screen reading software and shortcut keys to fully reflect information on the screen, the design and coding of all parts of the system would be consistent and contain adequate supporting data.
For convenience, Citigo suggested that dialogue boxes would be used instead of pop-up windows. With dialogue boxes, users would have to fill in the required information before moving to the next content. This would help users avoid being loss in a complicated system, containing various steps and information tabs. Besides, dialogue boxes are not blocked by some computer systems; therefore, users can avoid missing important requirements. In addition, Citigo also enabled the quick search function in every information form, facilitating the retailers in finding the needed information quickly.
Three months after the completion of the project, the system was launched successfully in 34 stores in Australia with nearly 100 employees who are blind or have low vision. Potentially, it will become one of the leading retailers systems in Australia with full accessibility to benefit disabled people, bringing them equal opportunity to actively participate in the society.
