This study aims to explore the potential and impact of using plants as interactive design objects. With increasing attention to nature and the pursuit of more meaningful user experiences, plants, as living and sentient entities, have garnered significant interest in the field of interactive design. Through theoretical analysis, this paper delves into key areas of using plants as interactive design objects. We examine the potential value of plants as user interfaces, including their form, color, texture, and their impact on user emotions and attention. Additionally, we investigate the perceptual abilities of plants and their response to external stimuli, exploring innovative ways to leverage these features for immersive user experiences. In the realm of emotional design, we emphasize the potential role of plants in conveying emotions and creating atmospheres, utilizing attributes such as shape, color, and growth rate to communicate emotional information and influence user mood and affective states. Furthermore, we explore the relationship between plants and sustainable design, exploring how to integrate the ecological functions of plants with interactive design to achieve more sustainable products and systems. Finally, we consider the influence of cultural factors on plant-based interactive design, underscoring the importance of incorporating and respecting diverse cultural elements in the design process. The findings of this study provide a theoretical foundation and practical guidance for using plants as interactive design objects, offering valuable insights for further exploration of the relationship between plants and interactive design.
