The project is based on a blend of technology, art, and psychology, utilizing shared experiences and emotions to foster a sense of connection or intimacy. The use of light as a medium for interaction adds a visually appealing and potentially immersive element to the experience. To cultivate an ambiance of closeness, the model projects universally resonant memories onto the walls through reflected lights. This approach engenders a friendly interaction between humans and light, facilitated by shared senses and emotions, and triggers an emotional rather than physical interaction with humans. By displaying memories that resonate with everyone on individual cubes, their shadows are cast upon the wall by an omni-directional light source. Positioned at the front, a unidirectional light gradually shifts its direction from left to right, creating a panoramic effect reminiscent of the memories being recounted. Consequently, the progression of memories unfolds chronologically on the wall, synchronizing with the passage of time. Additionally, the application of colored films on the cubes introduces a spectrum of diversity to our recollections, enhancing their richness and possibility. Furthermore, the broad color spectrum invokes enduring and joyful memories by virtue of the diverse positive effects it imparts, contrasting with the monotony of black-and-white or uniform hues. This effect evokes a strong interaction between humans and light. Cool light is preferred in this project as it reflects the clear shadow on the wall.
