Doraemon's Gadget Lab: Unpacking Human Needs and Interaction Design in Speculative Technology

Tram Thi Minh Tran

TL;DR

This paper investigates how Doraemon’s 379 canonical gadgets reflect enduring human needs and offer alternate interaction paradigms for human–computer interaction (HCI). Using a reproducible data pipeline, the authors categorize gadgets into 10 high-level groups and 33 subcategories, then map them to contemporary technologies to extract design insights. The findings show that while human needs persist, Doraemon’s designs emphasize tangible, single-purpose, reversible interactions, contrasting with today’s software-centric interfaces. The study argues for embedding, context-aware, and anticipatory interfaces as a pathway for future user-centered innovation, and it provides cross-cultural perspective by analyzing a canonical Japanese manga dataset and its implications for HCI design.

Abstract

Speculative technologies in science fiction have long inspired advancements in Human-Computer Interaction (HCI). Doraemon, a Japanese manga featuring a robotic cat from the 22nd century, presents an extensive collection of futuristic gadgets-an underexplored source of speculative technologies. This study systematically analyses 379 of these gadgets, categorising them into 33 subcategories within 10 high-level groupings, to examine the fundamental human needs they address, their parallels to contemporary technologies, and their potential insights for HCI design. The findings reveal that while human needs remain constant, the ways in which technology fulfils them differ. Doraemon's gadgets emphasise tangible, single-purpose interactions with built-in reversibility, contrasting with the increasing complexity and software-driven nature of modern systems. By examining these speculative technologies, this study highlights alternative interaction paradigms that challenge current HCI trends and offer inspiration for future user-centred innovation.
