Visibility, Feedback, Affordances, Constraints

UPDATE: please download the whole essay here: Four Cornerstones of User-Centered Design by Jiri Jerabek [PDF, 82kB]

Recently I spent many hours continuing my Graphic Design in Context module research and writing an essay about the conclusions of my presentation.

The module quite changed how I perceive the design as an industry and allowed me to dive into the depths of the interaction between the user and the product – whatever it may be.

What I learnt:

  • good design is driven by the behaviour and needs of the user, not by features and functions the manufacturer wants to put into the products
  • designer should not only give priority to the user’s needs, but to take on account the strategic goals of the manufacturer
  • design process is the key
  • research, wireframes, prototypes, user-testing
  • study of the user’s psychology is very important
  • Visibility, Feedback, Affordances, Constraints – important rules of user-centered design
  • for the user, the interface is the product
  • Metaphors and Direct Manipulation can help the user to create the conceptual model with ease (= to understand, how to use the product and what actions are available0
  • visual communication can make or break it
