Studying and improving the factors that influence the effectiveness and efficiency of computer use.D. Usability of computer-based systems.E. Human cognition.Options:1. A, C, D2. A, B, D, E3. A, C, D, E4. A, B, C, D5. All of the above.Question 2There are very few systems whose designers are typical of the user population. Users differ because of:1. age and gender only.2. level of expertise only.3. nationality or culture only.4. disability only.5. age, expertise level, nationality/culture and the impact of disabilities.Question 3Many people think an oven will heat faster if the thermostat is turned all the way to the maximumsetting. This is an example of:1. a design error.2. an incorrect design model.3. an incorrect mental model.4. naive physics.5. a lack of intelligence.Question 4The ‘computer’ in human-computer interaction is defined as including:1. A general desktop computer.2. A large-scale computer.3. An embedded computing device.4. A process control system.5. All of the above.Question 51. to design in such a way that the interface supports the requirements of different kinds of users.2. for the designer to consider himself/herself to be a ‘typical user’.3. to produce an interface that provides for use of both the keyboard and the mouse.4. to recognize the distinction between the designer’s view and the client’s model.5. None of the above.Question 6Which of the following statements and guidelines are accurate?A. As a designer, you should not view yourself as a typical user.B. Sophisticated interaction mechanisms will prevent errors and frustration.C. A well-designed interface will support novices in the process of becoming experts.D. As users, we should trust designers’ intuition.E. The gulf of evaluation is bridged if the user can determine whether or not he/she hasachieved the desired result.Options:1. All of the above2. A, B, C and D3. A, C and E4. A, B and D5. B, C, D and EQuestion 7Which of the following statements are accurate?A. The UNIX operating system was developed for expert users.B. Interaction via chords means simultaneously using menus and mice.C. Interface designers should collaborate with marketing experts in order to understandcharacteristics of their target users.D. If an interface is poorly designed, users tend to stop using it.E. Designers should design a user interface as if they, themselves, are typical users.Options:1. A, C and E only2. A, D and E only3. A, B and E only4. B and D only5. A, C and D only.Question 8The end-user’s mental model is influenced by:A. word processing and printers.B. their goals and intentions.C. the underlying algorithms and devices.D. their daily tasks.E. the objects and operation in the users’ tasks.Options:1. All of the above2. A, B, D and E only3. A, B and E only4. B, D and E only5. None of the above.Question 9HCI is a multidisciplinary field of study, incorporating:A. technologyB. ergonomicsC. physiologyD. perceptionE. cognition.Options:1. All of the above2. A, B and E3. A, B, D and E4. A, B and D5. None of the above.Question 10Consider the statements below. Only one is false. Which one is false?1. Preece’s (1994) model of HCI has four components, namely people, work, technologyand the environment.2. Dix et al (1998) define HCI as the study of people, computer technology and the ways inwhich they influence each other.3. The aim of INF1208 is not only to introduce HCI, but also to address the general issue ofuser-centered design.4. HCI is about people, computers and the environment, specifically the workplaceenvironment.5. HCI is a multidisciplinary subject. Designing and developing an interactive artifact isdone better by a design team than by an individual.Question 11One of the most important principles of design is visibility, the property by which the visible structureof well-designed objects gives clues to their operation. These clues are given by:1. stereotypes, mappings and affordances.2. affordances, constraints and mappings.3. conceptual models.4. mental models.5. causality and stereotypes.Question 12Perception is influenced by:A. maximum and minimum detectable levels.B. interaction with physical objects.C. background noise.D. biological rhythms.Options:1. A, B and C2. A, C and D3. A and B4. A and C5. A, B, C and D.
