Many digital graphic design tools provide design templates to help non-designers quickly get started. Users often have assets (e.g. images and text) that they want to incorporate when starting their design. Existing interaction schemes may be insufficient to help users adapt a template to work with their assets and hinder their sense of creativity and productivity. To investigate the effects of templates on non-designer workflows, we conducted a think-aloud design study (N=10) where participants designed posters using one or more templates, followed by semi-structured interviews. Our findings show that while templates help users converge to a final design quickly and partially alleviate the need for tedious decision-making, they may also lead to fixation and frustration when interactions do not support divergent thinking and flexible editing. We present design recommendations for creativity support tools (CSTs) that make use of templates, to address non-designers’ creative and practical needs.
