Abstract. All software today is written using libraries, toolkits, frameworks and other application programming interfaces (APIs). We performed a user study of the online documentation a large and complex API for Enterprise ServiceOriented Architecture (eSOA), which identified many issues and recommendations for making API documentation easier to use. eSOA is an appropriate testbed because the target user groups range from high-level business experts who do not have significant programming expertise (and thus are endparticipant developers), to professional programmers. Our study showed that the participants' background influenced how they navigated the documentation. Lack of familiarity with business terminology was a barrier we observed for developers without business application experience. Participants with business software experience had difficulty differentiating similarly named services. Both groups avoided areas of the documentation that had an inconsistent visual design. A new design for the documentation that supports flexible navigation strategies seem to be required to support the wide range of users for eSOA. This paper summarizes our study and provides recommendations for future documentation for developers.
Within the past few years, the field of HCI has increasingly addressed the issue of environmental sustainability, primarily identifying the challenges and developing an agenda for designing for sustainability. Yet, the most difficult task remains, how do we develop realistic solutions when the digital ethos is based upon short-lived computing products that come and go at rapid pace. By examining appropriation, re-use, and maintenance practices, this workshop aims to identify sustainable interaction design challenges and directions in re-utilizing used or obsolete computing products for prolonged use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
