Innovative interactive design of eco-friendly digitalwater lanterns based on emotional data

With the development of science and technology, digital technology has brought new possibilities to the field of environmental protection. As an innovative interactive design based on emotional data, the environmental protection digital water lamp combines environmental awareness and technological innovation, providing people with a unique experience. This paper takes the unique Lantern Festival in Xiamen as the starting point to discuss the balance between traditional cultural rituals and environmental protection. While maintaining the core values of cultural tradition, we should explore the new situation of environmental protection through innovative and interactive design. The digitization process driven by technological advances enables interactive devices to move beyond traditional communication methods. This study uses environmentally friendly materials and digital technologies to collect users' emotional data and display them in the form of digital water lamps to avoid river pollution. Through the interaction with the digital water lamp, the user releases the negative emotions and completes the prayer ritual. The two-way interaction of digital water lamps strengthens the personalized blessing experience and meets the needs of the contemporary conservation prayer culture.
