Start with the right requirements.
Interactive fountains respond to a button, movement, presence or another visitor input. The chapter focuses on the understandable relationship between action and response, including latency and simultaneous users. The technical architecture validates inputs, applies interaction rules and checks permission to operate before commanding equipment. Accessibility, sensor faults, privacy and operating states are considered alongside water contact; interaction alone does not establish that a fountain is designed for bathing or play. The chapter connects the visible effect with engineering and operating requirements, helping an owner compare options against site conditions, intended use and maintenance capability.
- Make the response understandable to users.
- Test simultaneous interaction and equipment limits.
- Define behaviour when a sensor fails.
