HCI II: Interaction Design and Usability Quiz, Exams of Nursing

Chamberlain College of NursingNursing

This is a set of multiple-choice questions and answers on human-computer interaction (hci) ii. It addresses interaction design definitions, design principles (visibility, affordance), usability goals (efficiency, utility, safety, memorability), user experience vs. usability, and interaction design phases. Questions cover user-centered design, conceptual inspiration, interaction types, and digital technologies' impact on social interaction, offering a broad overview of hci. Useful for students in hci, ux design, or related fields to test their knowledge. It also touches on agile software development in interaction design, conceptual models, metaphors, and the influence of digital technologies on social interaction, especially during physical distancing.

  2. By using an agile approach, developers can start coding immediately to save time and costs
  3. An agile approach does not require that all critical design elements are captured in a design document

Discuss the five key issues that any data gathering session requires in order to be successful - goals, choosing participants, triangulation, participant relationship and pilot. Assume that the management of the owning company of Telegram has decided to create an Africanised version of the app for the South African market: Discuss five common types of requirements discovery - - Implementation of emojis which can relate to African people more

  • Interface to suit the audience
  • Ease of use according to ergonomics
  • Security in order to ensure the privacy of the user.
  • Better AI to detect fake accounts in order to reduce fake news and wrong information and frauds. Explain to the CIO how the first version of the proposed Africanised version can be evaluated after the core functionalities have been implemented. Discuss various options of evaluation types briefly - The main types of evaluation are process, impact, outcome and summative evaluation. Before you are able to measure the effectiveness of your project, you need to determine if the project is being run as intended and if it is reaching the intended audience. Explain to the CIO how the first version of the proposed Africanised version can be evaluated after the core functionalities have been implemented
  1. Error Prevention: I tried deleting a message on telegram and it gave the proper warning before continuing with deletion of data
  2. Match between system and the real world: Telegram to have planned and silent messages for example set a timer on messages as to when you want to send them and as a silent message
  3. Flexibility and efficiency of use: Telegram already cater to both inexperienced and experienced users
  4. Recognition rather than recall: when deleting a chat it should be archived into a folder so one don't have to keep it on messages but can go to archive and search for messages. Which statement regarding data gathering for interaction design is correct?

  6. Structured interviews provide a shallow understanding of an interactive design space
  7. Semi-structured interviews provide a shallow understanding of an interactive design space
  8. Focus groups provide a shallow understanding of an interactive design space - Structured interviews provide a shallow understanding of an interactive design space Which statement is an advantage of focus groups regarding data gathering for interaction design?

  10. Understand what users do naturally and how technology impacts them
  11. Test hypotheses to discover new knowledge by investigating the relationship between two or more variable
  12. None of the above - Collect quantitative data to check that a system is usable by the intended user population Do an emotional interaction evaluation of the current version of Telegram. Please refer to the following aspects and suggest ways to Africanise the app in this regard:

How was the interface of the current version of Telegram designed to make customers respond in certain ways? How do these designs resonate with African users? - The current Telegram application, the design of which is a messaging and file sharing application was designed and developed while keeping the choices, preferences as well as the taste of the users all across the world. The UI allows the users to navigate through all the contacts and their respective chats while scrolling and selecting the chat that they want to interact with at a particular point in time. Now, as far as the African people are considered, their preference for joyfulness has been taken care of pretty well in this application as there are multiple options to add GIFs as well as stickers to make the conversation look a lot more vibrant than the WhatsApp. Do an emotional interaction evaluation of the current version of Telegram. Please refer to the following aspects and suggest ways to Africanise the app in this regard: Do you think the current interface is believable and trustworthy, and why? - Yes, it is pretty much believable and trustworthy as the organization itself is highly committed to cybersecurity as well as information security as well as the data privacy rights of their users. They have even included the feature that allows the users to delete the message any time and they can even edit the message once it is sent to the other person. These all are the reasons why this is a trustworthy and believable application. Do an emotional interaction evaluation of the current version of Telegram. Please refer to the following aspects and suggest ways to Africanise the app in this regard: Are there any annoying interface elements that could cause users to stop using the app? Motivate your answer - Although most of the features are added to the application to provide ease of navigation as well as interaction to the users of the telegram application, however, still there are certain features such as the inability to download multiple files at the same time, inability to send the voice messages, and the inability to find the activity status of the contacts are certain features that might lead the user to quit this application. Do an emotional interaction evaluation of the current version of Telegram. Please refer to the following aspects and suggest ways to Africanise the app in this regard:

b. Fitts' Law is a framework used to analyse large volumes of data to provide information about how a product is used. c. Fitts' Law is a theory that is useful for remote testing of small differences in the UX design of an interface. d. Fitt's Law is a pardigm used to evaluate the UX of FitApp's user interface. - a. Fitts' Law is a model that uses a formula to predict user performance during interactive design evaluation. Software that simulates human attributes in a pleasurable interface is: a. An example of the use of expressive interfaces b. An example of design at the behavioural level c. An example of zoomorphism d. An example of anthropomorphism - An example of the use of expressive interfaces Which one of Shneiderman's classic guidelines for error messages is violated by the following computer message: "The application Word Wonder has unexpectedly quit due to a type 2 error"? a. Error messages should be precise rather than vague. b. Error messages should avoid context-sensitive help. c. Error messages should avoid friendly cute images. d. Error messages should provide precise error code numbers. - Error messages should provide precise error code numbers. Which one of Nielsen's revised set of heuristics evaluates the principle of a pleasurable visceral design?

a. Flexibility and efficiency of use b. Aesthetic and minimalist design c. Visibility of systems status d. Match between system and the real world - Flexibility and efficiency of use Job description of an Interaction designer - 1. Determine the goals of the customers and what the necessary interactions are in order to achieve these goals.

  1. Compiling user, business and technical requirements to create product information architecture
  2. Creating wireframes and prototypes that illustrate key product interactions.
  3. Evaluating the product and the user experience When designing the Library information systems application, why does usability matter? - Usability matters because if users cannot achieve their goals efficiently, effectively and in a satisfactory manner, they are likely to seek an alternative solution to reach their goals. They need to ensure that the application is easy to learn, effective to use, and enjoyable from the users perspective. As an interaction designer of the new Library information systems application, you would need to collect stakeholder requirements. Identify three stakeholders and list them in the following table. - 1. Children of all ages
  4. Parents and their surrogates (non-parental caregivers, foster parents, etc.)
