One of the challenges end-users face in order to maintain and enhance their IT infrastructures is the simplicity and ease of use of the configuration/design-time interfaces. In this paper we describe ...our approach of using existing technologies for paper-based interfaces to allow end-users to orchestrate services in a Service-Oriented Architecture (SOA). We gathered first experiences with paper-based interfaces for IT configuration by developing an end-user-developable paper-based remote interface for interactive TV applications. Further we conducted a workshop to evaluate how end-user can orchestrate services. Here, we discuss the usefulness of a paper-based interface for the orchestration of services, from an end-user perspective and how the experiences from our prototype and the workshop can inform the design of a paper-based orchestration prototype for SOA.
We present a novel mobile memory aid tool, called ClickCatalog System (http://www.ht.sfc.keio.ac.jp/atreader/). In our daily lives, we find many interesting items during shopping, in exposition ...events, or in conferences. We often try to remember them for later recall by writing memos, taking pictures, etc. Those hints (notes and pictures) are, however, easy to be lost. Using ClickCatalog System, users can collect digital records of the items with an easy-to-handle hardware called @reader, which embeds an RFID reader. After a day, they can recall the stored records using a viewer software. The viewer can be operated using the same device, @reader, by manipulating it on a paper calendar (to recall the records temporarily) or on a paper map (to do so geographically). This paper shows the prototype implementation of ClickCatalog System, a range of applications, and, our empirical study using prototype ClickCatalog System.
