ABSTRACT
Sketching is known to support divergent thinking during conceptual ideation. Yet, in HCI teams, non-designers are known to be reluctant to sketch. Looking for a tool that could support non-designers' divergent thinking to creatively offset familiar solutions while providing starter suggestions, we hypothesized that LEGO pieces could replace sketching. In a comparative lab experiment, 36 participants did two conceptual ideations of Web interfaces, one using paper/pen, the other LEGO, in random sequence. The 72 resulting interfaces were assessed on their fluency, flexibility, elaboration and originality according to Guilford [6] and Torrance's [9] divergent thinking framework. Our main finding is that LEGO could substitute sketching for non-designers; the 3D figurative, constructive pieces provide a stimulating visual representation that supports divergent thinking by offering alternate meanings, generating a greater number of elements to react to, thus enhancing the use of analogies.

Painting with CATS: Camera-Aided Texture Synthesis
CHI EA '19: Extended Abstracts of the 2019 CHI Conference on Human Factors in Computing SystemsWe present CATS, a digital painting system that synthesizes textures from live video in real-time, short-cutting the typical brush- and texture- gathering workflow. Through the use of boundary-aware texture synthesis, CATS produces strokes that are non-...
