Summary .............................................................................. .. 9 Introduction CIT 711 – User Interface Design and Ergonomics is a three [3] credit unit course of twenty one units. It discusses the introduction, design, implementation and evaluation of user interface. The course material was clearly designed to enhance the understanding of students. The aim of this course is to equip you with the basic skills of studying and understanding the concept of user interface design. The techniques involved will be explicitely covered while evaluation procedures will also be discussed. By the end of the course, you should be able to confidently study, analyse and design a standard User Interface. This Course Guide gives you a brief overview of the course content, course duration, and course materials. What you will learn in this course The main purpose of this course is to provide the necessary tools analyzing and designing user interface systems. It makes available the steps and tools that will enable you to make proper and accurate decision about necessary design technique whenever the need arises. This, we intend to achieve through the following: Course Aims i. To introduce the concepts user interface design and egonomics; ii. To describe the various techniques for designing user interface; iii. To describe the practical implementation of user interface; and iv. To discuss the techniques for user interface evaluation. Course Objectives Certain objectives have been set out to ensure that the course achieves its aims. Apart from the course objectives, every unit of this course has set objectives. In the course of the study, you will need to confirm at the end of each unit if you have met the objectives set at the beginning of each unit. By the end of this course, you should be able to: i. the essentials of good interface design techniques iii. describe in general term, the concept of user interface design; 6
ii. describe design a standard user Interface;. iv. analyse an existing user interface design. explain the various types of challenges that could be encountered in designing a good user interface. describe the the various process of implementing designs; describe how to evaluate a given design Working Through This Course In order to have a thorough understanding of the course units, you will need to read and understand the contents, practise the steps by designing a standard user interface model. This course is designed to cover approximately sixteen weeks, and it will require your devoted attention. You should do the exercises in the Tutor-Marked Assignments and submit to your tutors. Course Materials These include: 1. Course Guide 2. Study Units 3. Recommended Texts 4. A file for your assignments and for records to monitor your progress.
