a) Human-Computer Interaction (HCI) is the study of the design, implementation, and evaluation of interactive computer systems for human use. It focuses on the interfaces between people and computers, and how they can be designed to make the interaction as efficient, effective, and satisfying as possible.<br /><br />b) The three principles for a user-centered approach are:<br />1. Involvement of users in the design process<br />2. Iterative design and testing<br />3. Emphasis on usability and user satisfaction<br /><br />c) The three types of studies in Value Sensitive Design are:<br />1. Ethnographic studies<br />2. Comparative studies<br />3. Case studies<br /><br />d) The design implications of attention include:<br />1. Focusing on the user's goals and tasks<br />2. Designing interfaces that are visually appealing and easy to navigate<br />3. Providing feedback and guidance to the user<br />4. Ensuring that the system is responsive and efficient<br />5. Considering the user's cognitive and physical abilities<br /><br />e) The principles of human-centered design include:<br />1. Understanding the user's needs and goals<br />2. Iterative design and testing<br />3. Emphasis on usability and user satisfaction<br />4. Involvement of users in the design process<br />5. Considering the user's cognitive and physical abilities<br /><br />1) Some problems with online questionnaires include:<br />1. Low response rates<br />2. Incomplete or inaccurate responses<br />3. Technical issues such as server errors or compatibility problems<br />4. Lack of personal interaction<br />5. Difficulty in verifying the identity of respondents<br />6. Privacy concerns<br />7. Difficulty in reaching a diverse sample<br />8.
