Week 2-1 Readings & Questions • Readings • Meister (2003) • Questions • What is the state of our knowledge in HF? • How well is HF knowledge progressing? • How well is HF knowledge being applied to technological design? • What factors impede or facilitate the progress and application of HF knowledge?
Meister’s (2002) Self Examination • Self-examination and some dissatisfaction are needed to advance the discipline. • Questions to ask: • How well can we predict? • Does our work significantly improve design? • Do our theories expand understanding of the human/systems interaction?
What has changed in 25 years? • From a review of the Proceedings of the HFES conference Not much • What has remained the same: • Reliance (if not increased reliance) on the experiment 64% in 1974, 80% in 1999. • Very little written about system design and development (10% 6%) • Limited development of theory (19% 24%) • Limited applications of research findings (23% 34%) “airy abstractions” • Tightly constrained studies with clear-cut stimuli (68% 58%) • More emphasis on molecular than molar issues.
What has changed in 25 years? • From a review of the Proceedings of the HFES conference Not much • What has changed • Increased emphasis on empirical research to non-empirical (tutorial/case history/analysis) papers (1974: 30-70%, respectively; 1999 70-30%) • More emphasis on molecular (workstations, interfaces) than molar (system-oriented) issues (38% 24%)
Goals of HF • Support understanding of the relationship between humans and their technology • Aid in the design and development of human-machine systems • Can data collected to address the first goal be used for the second goal as well?
Applying Research Results to Systems? • If HF research cannot be used in the design process, it has little value. • The lack of applicability might stem from the dominance by academics and experimental methods. • Experimental methods produce experimental data that are often difficult to apply.
Academic dominance • Represents a natural progression of the discipline. • Academic institutions are the recipients of government funding. • Academics have as a requirement the need to publish. • Journals prefer academic methods. • Old research is the most common stimulus for new research.
Self Examination • To advance, we must understand how we know what we know (epistemology). • The “automatic” methods cannot be simply applied to solve design problems. • To advance, we must be willing to ask ourselves if HF research has value.
