2Definition of HCI
- Human Factors in IS (HCI) is the scientific
study of the interaction between people,
computers, and the work environment. The
knowledge gained from this study is used to
create information systems and work environments
which help to make people more productive and
more satisfied with their work life. (Beard
Peterson, 1988) - Consensus definition from the HFIS Symposia series

4Huber, Management Science 1983
- Cognitive Style as a basis for MIS and DSS
designs Much ado about nothing? - This article had a dampening effect on studying
human computer interaction due to the prestige of
Management Science and the limited means
available to measure cognitive style at the time - At the time, most MIS researchers studying
human/computer interaction used Myers/Briggs type
indicator to measure CS

8Research Agenda for HCILewis (1990)
- 1. Understand user goals and preferences
(interface design theory) - 2. Broaden applied cognitive theory (problem
representation) - 3. Support innovation (technology to support
interface design) - 4. Credit assignment (measure the impact of
interface design on performance)

10Measurement Issues in HCINewsted, Todd, Zmud,
1997
- Theories require constructs constructs require
measurement, therefore no theory without
measurement - Definitional concerns (conceptual ambiguity and
conceptual overlap) - Concerns with construct-context interaction (such
as the tight construct-context linkage in task
performance) - Zmud Boynton criteria for instrumentation
- Multiple-item scale
- Ability to find and use an instrument
- Description in refereed source
- Assessment of psychometric properties
- Classifying measures
- Outcome versus process measures
- Perceptual versus behavioral measures
- Obtrusive versus non-obtrusive measures
- Qualitative versus Quantitative measures
11Measurement Issues in HCINewsted, Todd, Zmud,
1997
- Instrument validation for experimentation
- Construct validation
- Manipulation measurement
- Covariate measurement
- Experimenter effects
- Online data capture
- Conclusion HCI measures are improving, but have
a long way to go
