This book constitutes the refereed post-conference proceedings the 6th EAI International Conference on Design, Leaning and Innovation, DLI 2021, which took place in December 2021. Due to COVID-19 pandemic the conference was held virtually. The theme for DLI 2021 was "Shifting boundaries to discover novel ways and emerging technologies to realise human needs, ideas, and desires" targeting a conceptualisation of the effects and impact of digital technologies for, in an inclusive and playful way, fostering human beings to realising their needs, ideas and desires.
