A pragmatic HCI approach: engagement by reinforcing perception with functional dsesign and programming

In order to provide effective human interaction with a computer interface, the design process must consider human cognitive factors. From an educational perspective, this area encompasses a range of issues which, because of academic time constraints, might be difficult to focus on, particularly if practical design and implementation are part of the syllabus. The paper describes how focusing on one area of perception with unusual and challenging perceptual images promoted quick interface design, provided stimulation for programming a working interface and highlighted the value of factors such as perception and affordance in the design of screen objects. A later formal series of questions revealed that learners saw the importance of human factors and the relevance of such issues in the design process as well as providing an incentive for programming a working model.
