The Talking Plants, an interactive system for learning about food growing. The project was developed and evaluated at Spitalfields City Farm, a community farm in inner east London, UK. Visitors can approach the plants and use a watering-can augmented with RFID (radio frequency identification) technology to hear them talk. The plant voices come from staff and volunteers, reflecting the cultural diversity of the community. We describe development of the project and findings from our evaluations. Users found the system to be engaging, easy to use and provided an effective and enjoyable way to learn about growing and preparing edible plants.
