Human-Computer Interaction 2015 Flashcards
Define Fitts’ Law. Why do we study it in HCI?
Human-Computer Interaction 2015
Define Index of Difficulty and Index of Performance. Describe what each can be
used for in HCI
Human-Computer Interaction 2015
How could you use Fitts’ Law to improve the interface of a desktop application?

State the two main parts of the human haptic system and then describe the
relationship between them.

Pear Corporation is developing a new mobile phone that is intended to be the best
in the market. As part of the work, they want you to provide a report on the
different technologies that can be used to present vibrations.
Human-Computer Interaction 2015
Identify three technologies that can be used to communicate information through
vibration and give a brief outline of how each works.
Human-Computer Interaction 2015
Compare and contrast each technology in terms of cost, quality of feedback and
localisation of feedback.
Human-Computer Interaction 2015
Where in the user interface would you recommend that thermal haptic feedback
be used? Why?
Human-Computer Interaction 2015
Weiser proposed an approach to interactive system design called ‘ubicomp’, and
highlighted some of the types of computing needed to achieve it. Describe what
ubicomp is, and briefly outline Weiser’s own vision of ubicomp and his views on
it. In your answer, list the three different sizes of device Weiser believed were
necessary to ubicomp, and give an example item of hardware for each size.
Human-Computer Interaction 2015
Ubicomp systems are often designed for use in social settings with patterns of use
being open or contextually dependent rather than being defined by a narrow set of
tasks. What kind of evaluation approach is best suited to understanding such use?
In your answer, outline the approach and justify your choice.

Large scale trials of mobile apps can be difficult to do but the ‘hybrid approach’
is presented as a means to do them well. Explain why such trials can be difficult,
what the hybrid approach is, and describe how this approach can help developers
perform such trials.
Human-Computer Interaction 2015
What are the two dimensions that can be used to categorise different forms of
CSCW systems? Provide an example for each category based on these
dimensions.
Human-Computer Interaction 2015
List and describe the four core CSCW concepts. Then, choose a work setting and
sketch out a CSCW systems design that covers all four concepts.
Human-Computer Interaction 2015
What are the main ethical challenges raised by the use of app stores to distribute
research software? What can be done to improve this situation?
