The Veggie School Festival Educational Exhibition

The tactile and audio systems in The Veggie School Festival Educational Exhibition were developed from an accessibility and educational question: how could visitors, including visually impaired participants and young children, understand plants and agriculture without relying only on visual information?Our team designed an interactive system in which sensor patches were embedded into plant-shaped installations. When visitors touched a plant, the system would respond with sound. Different plants produced different sounds, allowing visitors to discover that each plant had its own “voice” within the exhibition.This interaction was not designed merely as a technical function. It was created to communicate an ecological idea: plants are not passive or silent beings. They can sense changes in their environment and respond to the world around them. They also communicate with other plants through various natural signals. By giving each plant a sound response, we transformed this scientific concept into an intuitive, emotional, and memorable experience.For the sensitivity calibration, we paid close attention to how different users would touch the plants. Children may tap quickly, press repeatedly, or explore with excitement, while visually impaired visitors may touch more slowly and carefully to understand the form and texture. Therefore, the sensors needed to respond clearly to intentional touch, while avoiding accidental triggers that might confuse the narrative.We also adjusted the timing, volume, and character of each sound. If the response was too delayed, visitors might not connect their touch with the plant’s reaction. If the sound was too loud, too long, or too similar across different plants, the experience would become less meaningful. Our goal was to make each response feel like a gentle conversation between the visitor and the plant.For us, the conductive sensing and responsive audio system was a tool for knowledge translation. Through touch and sound, visitors could experience the idea that plants are living beings connected to their surroundings, rather than static objects displayed in an exhibition. This helped make agricultural knowledge more accessible, especially for children and visually impaired participants.

During the development of The Veggie School Festival Educational Exhibition, user testing with children and visually impaired participants changed our understanding of accessibility in a very practical way.At the beginning, accessibility could easily be understood as a matter of physical access, such as ramps, circulation routes, signage, or basic safety. These are essential, but through testing we realized that genuine accessibility in a public learning environment requires much more than allowing people to enter the space. It requires allowing them to participate in the meaning of the exhibition.When we observed how children and visually impaired participants interacted with the tactile and audio installations, we learned that access is not only about movement, but also about rhythm, clarity, confidence, and emotional connection. Some visitors needed more time to explore with their hands. Some children touched quickly and repeatedly. Some participants understood the story better through sound, while others needed a clearer relationship between touch, object, and response.These observations led us to adjust many details: the height and position of interactive elements, the texture and scale of plant forms, the sensitivity of the sensor patches, the timing of the audio response, the length and density of the narration, and the way visitors were guided through the experience. We also became more aware that sound should not simply provide information. It should help visitors build a spatial and emotional understanding of the agricultural world.One important lesson was that accessibility should not create a separate experience for visually impaired visitors. Instead, it should create a shared sensory language that allows visually impaired and sighted participants to learn together. In this exhibition, touch and sound were not supplementary features; they became central ways of understanding plants, agriculture, and the relationship between living beings and their environment.Through this process, we came to see inclusive design as a continuous act of listening and adjustment. It is not a checklist completed at the end of the project, but a design attitude that must shape the exhibition from the beginning. For us, genuine accessibility means that different visitors can enter the same story through different senses, and still feel equally invited, respected, and able to understand.

I believe the transferable value of this methodology does not lie only in the hardware itself, but in the way it transforms food systems into a shared sensory learning experience.Many urban residents are physically and emotionally distant from the processes that produce their food. Agriculture is often understood through labels, statistics, or environmental slogans, but these forms of communication can still feel abstract. In The Veggie School Festival Educational Exhibition, we tried to use conductive sensor modules and responsive audio systems to turn crops, soil, seasons, and farming environments into something visitors could touch, hear, and explore with their bodies.This methodology can become a useful model for other civic institutions because it provides a flexible structure. A museum, school, library, community center, or public exhibition can adapt the same logic to its own local food culture and agricultural issues. The plants, sounds, stories, and scientific messages can all be changed according to the region, while the core principle remains the same: translate invisible systems into sensory interaction.For example, instead of simply explaining that plants respond to environmental changes, we allowed visitors to touch plant installations and hear different sound responses from different crops. This helped communicate that plants are living beings connected to their surroundings, and that agriculture is not only about production, but also about relationships among soil, water, climate, plants, insects, farmers, and consumers.The important point is that technology should not become the main character. It should serve as a bridge. In this project, the sensors and audio responses were used to create curiosity, emotional connection, and accessibility. They helped children, visually impaired participants, and sighted visitors enter the same story through different senses.For civic institutions, this offers a practical model: begin with a local issue, identify the knowledge gap, translate key concepts into tactile and auditory cues, test the experience with real users, and refine the interaction until it becomes intuitive and meaningful. Through this process, public education can move beyond passive information display and become an embodied experience.In this sense, The Veggie School Festival Educational Exhibition suggests that agricultural education in cities does not have to remain distant from daily life. With thoughtful design, food systems can become something people can feel, listen to, and understand together.
