We also describe how different contribution types have been codified in the CHI submission process.For the CHI 2016 conference, we show how the submitted and accepted papers were distributed across contribution types, providing insight into the kinds of knowledge the HCI field develops and disseminates.
Insights As is often observed, HCI is highly inter- and multidisciplinary. It has taken a few decades for the types of knowledge in HCI to emerge, converge, and stabilize, and new ways of knowing still swirl about .
But over time, an identifiable pattern of research contribution types has evolved.
New systems, architectures, tools, and toolkits are evaluated in a holistic fashion according to what they make possible and how they do so .
New input and interaction techniques, by contrast, are evaluated precisely and quantitatively so as to isolate their human performance benefits.
In the whole of human inquiry, there are, of course, countless specific research contributions to be made.
But the types of these contributions—the general forms this new knowledge takes—are relatively few.Empirical research contributions are evaluated mainly on the importance of their findings and on the soundness of their methods.If empirical findings are uninteresting or unimportant, or if the methods by which those findings arise are sloppy, imprecise, or confounded, then empirical contributions are judged unfavorably.Seven Research Contribution Types in HCI In 2012, the first author posted an unpublished whitepaper to his academic website describing seven research contribution types in HCI .This whitepaper was used as a source in creating the contribution types for the new CHI keyword structure.New design expressions, including sketches, mockups, and envisionments, are evaluated by how insightful, compelling, and innovative is their portrayal.Of particular importance is how well designs negotiate trade-offs and hold competing priorities in balance.Examples Artifact Contributions HCI is driven by the creation and realization of interactive artifacts.Whereas empirical contributions arise from descriptive discovery-driven activities (science), artifact contributions arise from generative design-driven activities (invention).The whitepaper presented seven research contribution types, how they are judged, and specific examples of each.Here we summarize those contribution types, with examples.
