Chapman, C.N. (2011). Model-based estimation of CBC attribute impact [poster]. Presented at the 22nd annual Advanced Research Techniques Forum, (A/R/T Forum), Desert Springs, CA, June 2011.

Abstract: A long-standing problem in choice-based conjoint (CBC) studies is determining attribute importance (i.e., the effect of a specific feature in determining a customer’s preference for a product). The idea of feature importance is obviously salient to product managers, but current methods are not completely satisfactory to estimate it. I review those problems and propose a new method to estimate attribute impact by examining how preference changes as attribute data is systematically decoupled from observed choices.

Chapman, C.N., Love, E., Burgess, S., and Lahav, M. (2010). Consumer usage of a digital memory device prototype. Proceedings of the 43rd Hawaii International Conference on System Sciences (HICSS), Poipu, HI, January 2010.

Abstract: We report qualitative consumer field trials of a prototype digital memory device known as SenseCam. We presented SenseCam to 25 consumers in the US (N=9), Japan (N=8), and South Korea (N=8) to determine initial interest and expected use cases. This was followed by respondents using an actual prototype camera for approximately one week and reporting on their experience. Actual use cases differed substantially from those initially expected by respondents. The results suggest that successful usage may emphasize stationary capture relatively more than moving scenes, and may emphasize recording of full scenes rather than recording outwardly from the body of what one has seen. We discuss implications for concepts of digital memory and suggest that general consumer interest in such a device may be related to construction of interesting narratives rather than the capture and review of factual data.

Chapman, C.N., Love, E., Milham, R.P., ElRif, P., and Alford, J.L. (2008). Quantitative evaluation of personas as information. Proceedings of the Human Factors and Ergonomics Society 52nd Annual Meeting, New York, NY, September 2008, pp. 1107-1111.

Abstract: We propose a formal model to understand persona information in terms of factual attributes. Using an analytic model, we show that the expected prevalence rate of persona descriptions decreases rapidly as attributes are added. We then evaluate this expectation empirically, using six survey datasets ranging from N=268 to N=10307 respondents. Because descriptions with many attributes are likely to represent few people, we suggest that personas should be assessed empirically before they are assumed to describe real groups of people.

Chapman, C.N., Lahav, M., Love, E., and Alford, J.L. (2009, April). Product Interest and Engagement Scale, Beta (PIES-beta): Initial Development. Work in progress presented at CHI 2009, Boston, MA, April 2009.

Abstract:We report a work in progress: development and initial validation of the Product Interest and Engagement Scale (PIES), a short assessment instrument measuring consumer interest in technology products. PIES reflects an explicitly multidimensional, hierarchical, and extensible model of product interest. PIES-beta is suitable for usage now but will undergo further revision in 2009.

Chapman, C.N., Love, E., and Alford, J.L. (2008, January). Quantitative Early-Phase User Research Methods: Hard Data for Initial Product Design. Paper presented at Hawaii International Conference on System Sciences (HICSS), Waikoloa, HI, January 2008.

Abstract: We describe questions that commonly arise in early-phase user research for new technology products concerning customer needs, priorities, and market definition. We suggest that methods adopted from marketing research, statistics, and game theory may be helpful for user researchers to answer those questions.

Chapman, C.N., and Milham, R. P. (2006, October). The persona’s new clothes: methodological and practical arguments against a popular method.  Paper presented at Human Factors and Ergonomics Society (HFES), 50th annual conference, San Francisco, CA, October 2006.

Abstract: We examine the popular Personas method and consider claims that personas can reflect empirical data and serve as an information source for development teams. We argue that there are significant methodological and practical difficulties for personas. Until the methodological issues are resolved, it is best not to consider personas to be a means to communicate data.

Chapman, C. N., Deaton, L., Harris, A., and Robinson, N.  (1999, July).  A genetic algorithm system to find symbolic rules for diagnosis of depression.  Paper presented at the IEEE Congress on Evolutionary Computation, Washington, DC.

Abstract: A machine learning method is proposed for automatically finding psychiatric diagnostic rules. It is proposed that a genetic algorithm (GA) system can find symbolic, easily readable rules that could be used by psychiatric clinicians.
