Alternative Strategies
•Consider the information seeker’s context
–Cognitive accessibility (it does not matter how good the results are if the information cannot be easily understood)
–Cost-benefit assessment (it does not matter how good results are if there is no time to use it)
•Study special populations (cell biologist vs. practicing physician)
•Usability testing approach (iterative, impressionistic)
•Systematic case studies
•Epidemiology approach (start with outcomes and trace influences)
•Develop an IR interaction model

interaction model: based on GOMS, see Dunlop SIGIR 97 paper
