“…Sketching and hand-drawn visual representations are important as a general method withing the HCI community, with Buxton, Greenberg, and colleagues outlining the many diverse sketching strategies (often borrowed from disciplines such as product design or engineering) that can be applied throughout the whole process of interaction design [13,22]. Similarly, Baskinger positioned sketching as an important method in interaction design [4], and Lewis et al emphasized the value of sketches to support interface design, participatory design, or reflective practice [31]. Hand-drawn sketching can also "be an integral part of focused research projects" [50,51], such as for studying situated visualizations [12], use of personal finance tools [30], and many other contexts.…”
