Accessible Design
Accessible Design
Accessible Design is thinking about who is going to be using the system, and how easy and intuitive the system is to operate. Accessible Design considers people other than the "average" user. Accessible thinking and design is asking the question:
$$ \text{Who might not be able to use this system, and why?} $$
When designers fail to consider these populations, people can be unintentionally excluded from using their system.
When the Sydney Opera House was originally designed, access relied heavily on stairs and tiered seating, which made it difficult or impossible for people using wheelchairs or with limited mobility to move independently through the building. At the time, accessibility needs were not a consideration in large public architecture, and the normal user was assumed to be able-bodied. As a result, some audiences and performers were effectively excluded from fully using the space. Later modifications improved accessibility, but the need for these changes indicate how failing to consider all users early can embed exclusion into a system.
Intuitive Design
Check out the screen shot of the travel app. You know how to like something, see your profile, favourite something, check your schedule... and yet you've never see it before. You already know how to navigate that application because it has been built on ideas that came before.
Intuitive Design is building on what already exists. What colour should a go button be? What colour should a stop button be? What colour should an LED be to indicate a good radio connection? You will not be reinventing these things, but taking into consideration how your system will be usable without having to have a specific training session on how it works.
User Feedback
Diverse input during development and construction leads to more ethical designs. You should seek feedback from people other than your teacher and close peers in regards to your designs.
Seek and document feedback from multiple sources in your design and development testing.
The more demographics, cultures, and sub-cultures that have input in the development of a project, the broader the understanding of the impact of that project.
