ITC504 Week2-Understanding and Conceptualising Interactions

In understanding the problem space a designer has to understand

• What do you want to create?

• What are your assumptions?

• Will it achieve what you hope it will?

• All of the above

What is True about assumptions and claims ?

• A claim is taking something for granted when it needs further investigation.

• An assumption is stating something to be true when it is still open to question.

• An assumption is taking something for granted when it needs further investigation

• All of the above.

A conceptual model is

• a high-level description of how a system is organized and operates

• a detailed description of how a system is organized and operates

• a low-level description of how a system is organized and operates

• Non of the above

Which describes Interface metaphors

• Conceptualizing what we are doing, e.g. surfing the web

• A conceptual model instantiated at the interface, e.g. the desktop metaphor

• Visualizing an operation, e.g. an icon of a shopping cart for placing items into

• All of the above.

Which of the follow does not describe interface metaphors correctly.

• Interface designed to be similar to a physical entity but also has own properties. e.g. desktop metaphor, web portals

• Can be based on activity, object or a combination of both

• Exploit user’s unfamiliar knowledge, helping them to understand ‘the unfamiliar'

• Conjures up the essence of the unfamiliar activity, enabling users to leverage of this to understand more aspects of the unfamiliar functionality

Which of the following is a benefit of interface metaphors?

• They makes learning new systems easier.

• They Help users understand the underlying conceptual model

• They can be very innovative and enable the realm of computers and their applications to be made more accessible to a greater diversity of users.

• All of the above

Which is an advantage of interface metaphors

• Break conventional and cultural rules. e.g. recycle bin placed on desktop

• Helps users understand the underlying conceptual model

• Can constrain designers in the way they conceptualize a problem space

• Conflict with design principles

The four main interaction types are

• Instructing, conversing, manipulating and exploring

• Instructing, conversing, manipulating and exploiting

• Instructing, conversing, maintaining and exploring

• Introducing, conversing, manipulating and exploring

Shneiderman (1983) describes Direct Manipulation as

• Continuous representation of objects and actions of interest

• Physical actions and button pressing instead of issuing commands with complex syntax

• Rapid reversible actions with immediate feedback on object of interest

• All of the above.

Which interaction type to choose does not depend on?

• determining requirements and user needs

• Take budget and other constraints into account

• the number of users

• suitability of technology for activity being supported
