These use under realistic conditions “in the field.” Reflexively, experiences and discussions with research scientists and mobile technology also creates new opportunities for data usability specialists point to a need for efficient, non- collection while participants are remotely located. We intrusive data collection methods that yield informative, report on our experiences with a variation on the paper- naturalistic data when studying issues of mobility. based diary study technique, which we extend by using We offer this paper as one response to these data collection voice-mail paired with mobile and landline telephony to challenges, with an in-depth discussion of the voice-mail more easily collect data in natural situations. We discuss diary study technique (see Mark’s approach [11] as another lessons learned from experiences with voice-mail diary interesting response). Our discussion is not intended to be studies in two investigations of different scope. We also a rigorous analysis of the diary study method in present suggestions for tailoring the technique to different comparison to other data collection methods. Rather, this research objectives, garnering high subject participation, paper is meant to serve as an introduction to an approach and configuring the voice-mail system for data collection.
