Human-Computer Interaction 2013 Flashcards
Perspectives on human-computer interaction shifted during the 1980s. Interaction
was no longer just seen as something that occurred between a user and a machine.
Describe three issues that contributed to this perspective change.

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

Imagine that you are developing a system that tracks people’s locations, for
example via GPS, and lets each user share his/her location with others. Show how
Bellotti and Sellen’s framework can help you design for privacy in this case.

Focus and context techniques use a degree-of-interest (DOI) function to
determine what information to visualise, given the current focus. Write out
pseudocode for an example DOI function and explain how it could be used to
allow focus and context-browsing on a 2D map.

You are tasked with creating a visualisation for a family tree. This is a
hierarchical data set, showing parent and sibling relationships. A data set may
contain hundreds of names.
Describe and sketch out a design for an InfoVis tool for this task. Your tool can
be interactive. Explain how you would cope with large data sets that would ‘fan
out’ quickly towards the bottom of the hierarchy. What other visualisation
challenges would such a data set pose?
