In this study, an AR-based digital artwork called "Mind Log" was designed and evaluated. The augmented reality technique was employed to create digital artwork that would present interactive poems. A digital poem was generated via the interplay between a video film and a text-based poem. This artwork was created following a rigorous design flow, including: (1) conceptual formation, (2) prototype design, (3) expert-based evaluation that consisted of both a cognitive walkthrough and a heuristic evaluation, (4) the final artwork design combining a visual poem generator and an AR system, and (5) a series of evaluations from an audience's perspective. The system usability scale evaluation results show that this work achieved positive usability, audiences enjoyed the interaction with the artwork, and most people accepted AR-based digital poems.
