The methodical study on the interaction between people, products, and environment based on experimental assessment. Efficiency − The competence used in using the resources to effectively achieve the goals. Which of the design principles might be described with "The interface should be based on user-oriented terms and concepts rather than computer concepts. Software Engineering Tools − Extensive programming tools to provide user interface management system. These 10 rules of thumb further iterate upon Shneiderman’s eight golden rules 4 years after Shnei… DESIGN STRATEGIES-2 Object-oriented design Is based on the idea of information hiding. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design.
