- a diagram showing the degree of connection between people in social networks
- a diagram used to show people\s cultural affinities or sense of belonging togroups.
- a diagram that organises individual ideas and insights into a hierarchy showingthemes
- a variant of a tag cloud that is generated from think- aloud protocols.

- a variant of a tag cloud that is generated from think- aloud protocols.
Q22 | Which is the best definition of an interaction mode?
- in broad terms, the kind of technical and software framework within which human system interaction takes place (e.g., wimp, mobile, tangible)
- an idea from the world that is used in the interface to help the user understand what to do (e.g., click on tabs to change window contents, use shopping cart to store items to purchase)
- what the human does to make inputs and receive information from the system (e.g., click and drag an object, talk to an object, move self closer to an object, converse with anentity, etc)
- the conceptual model used to guide the design of the interface.
Q23 | Regarding the measurement of usability attributes:
- reliability is measured by performing common use cases
- errors are measured by counting minor and catastrophic errors made byusers.
- learnability is determined by measuring the time it takes to explain an interfaceto a new user
- users are needed to measure efficiency
