Abstract
This paper describes the Retail User Assistant (RUA), a prototype system that provides continual adaptive help for the use of an existing retail point-of-sale device. A preliminary study compared performance of three groups: one using the retail device alone, one using the device with a nonadaptive version of the RUA, and one with the adaptive RUA. Trends in the results imply that performance support, both adaptive and nonadaptive, improved accuracy but slowed performance. The RUA's adaptation, which gave less detailed help as users learned the task, was readily accepted by users and seems to have improved users' performance times. This result is discussed in the context of previous research on adaptive help and adaptive interfaces.
