early stage tools and techniques for iterative evaluation

1. early stage tools and techniques for iterative evaluation the application development paradox scott davidoff, scott carter + jennifer mankoff

2. example paradox: eldermail (davidoff, bloomberg, li, mankoff + fussell 2005) • create a walk-up-and-use cmc system for seniors • provide benefits of email wrapped in familiar objects • challenge • strategy option 1 letter-writing-to-email bridge how could we know which to build and test option 2 voice-to-email bridge

3. the application development paradox • field-deployable research requires knowledge that researchers do not yet have

6. current tools + techniques toolkits interface builders build simulation paper prototyping iterative evaluation design test >> formative evaluation summative evaluation

7. current tools + techniques toolkits interface builders build paper prototyping iterative evaluation bootstrap simulation design test >> formative evaluation summative evaluation

8. bootstrapping location awareness: momento (carter + mankoff 2005)

9. comparing multiple approaches where is the sweet spot? overhead high low intrusiveness high low development cost easy hard momento bluetooth java

10. future work • support application development process from design to testing • support multiple prototype iterations, and seamless switching between them • low-cost channels to capture and visualize data from a variety of protocols
