Multisensory Interactions with Biophilic Flying Robots

The relationship between nature and humanity has evolved throughout history and across technological epochs. This thesis advances the hypothesis that integrating natural characteristics into robot design can enrich human–computer interaction (HCI) by drawing on our deep-rooted familiarity with and affinity for the natural world. To investigate this proposition, I examined close-range interactions with flying robots under different proxemic conditions, employing a mixed-methods approach.

The thesis comprises four empirical studies, each probing a different pathway through which biophilic elements might shape human perception, interaction, and imagination. Study I examined how overlaying natural soundscapes such as birdsong and rainfall affected the perception of a noisy flying robot (N = 56). Study II explored nature narratives, particularly the conceptualization of indoor drones as animal-like companions through function framing (N = 60). Study III compared experiences with a bioinspired flapping-wing drone—foregrounding organic forms and biomimetic movement—against a similarly sized quadcopter (N = 56). Study IV staged a speculative dinner theater in which participants (N = 6) engaged with the provocative scenario of eating a biohybrid drone, highlighting hybrid living components as a design material. Across these studies, variations in spatial proximity (from very near to relatively far) and temporal framing (from near- to far-future scenarios) were integrated to reveal how context shapes engagement and experiences.

Collectively, the findings show that nature-inspired design elements can foster intuitive, relatable, and emotionally resonant interactions with flying robots, while also surfacing ethical and practical challenges. This thesis contributes empirical insights into how people respond to biophilic flying robots and argues for moving beyond surface-level biomimicry toward intentional, context-aware integration of natural elements. By treating nature not merely as aesthetic inspiration but as a lens for crafting meaningful, embodied interactions, we can design technologies that resonate more deeply with human experience—particularly in close-range, affective, and everyday settings.
