Design Research (DR) creates, builds, and evaluates innovative artifacts such as constructs, models, methods, and instantiations as well as operational information systems. It also investigates approaches, methods, behaviors, and processes related to design. Although the design research paradigm as an engineering approach in Information Systems (IS) research has been actively discussed in recent years (Hevner et al., 2004), comparatively little design related research has made its way into the IS community by means of widely recognized and outstanding publications. Human-Computer Interaction (HCI) Research is concerned with the ways humans interact with information, technologies, and tasks; especially in business, managerial, organizational, and cultural contexts (Zhang et al., 2002). Despite the realization that it is important for HCI research to focus on all issues that occur along the lifecycles of any information and communication technology (ICT) artifacts, IS scholars have traditionally put less effort into the design and development stage and more effort into the use and impact stage (Zhang and Li, 2005;Zhang et al., 2009).We contend that the Design Research stream and the HCI research stream are inherently related and highly overlapping, representing different perspectives and approaches toward similar objects: ICT artifacts that humans interact with for various purposes. It is important to encourage active research efforts to make progress and research contributions at the intersection of these two streams. The goal of this special issue is to focus scholars' attention on this intersection and to provide an opportunity for active researchers in both DR and HCI to showcase their current work using the DR paradigm to address broad HCI issues.We see design research as a particular perspective within IS research, focusing on the development of artifacts related to ICT. DR involves the analysis of the use and performance of designed artifacts to understand, explain, and, very frequently, improve on the behavior of the social system that the artifacts become a part of. Such artifacts include -but certainly are not limited to -algorithms (e.g. for information retrieval), human-computer interfaces, system design methods, management policies, and full system instantiations. In this way, DR has a clear applied and creative orientation. The application of design research to human-computer interaction represents a unique set of challenges due to the multidisciplinary nature of the HCI field. HCI research draws from a large number of existing disciplines including cognitive science, computer science, education, engineering, graphic design, human factors, information systems, library and information sciences, management, psychology, and sociology. A key tension in HCI is the perception that there is a divide between the 'hard' and 'soft' sciences that ground HCI research (Carroll, 2006). The seminal works of Herbert Simon with his Sciences of the Artificial (Simon, 1996) and Allen Newell with his theoretical charact...
