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

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
