The project originated with the goal of creating an interactive light and sound installation for Highlight Delft, an innovative art and technology route. This involved incorporating holographic projection and spectral tuning to convey a specific perceptual phenomenon. The initial phase included extensive research into holographic projection, spectral tuning, and a broad literature review on perception. Experimentation with acquired knowledge informed the practical application, distinguishing effective principles and guiding the design process.

From the experimentation phase, three design directions emerged, with the idea of projecting coloured visuals on multiple layers of semi-transparent textile standing out. Tuning the projection in terms of colour and timing allowed visuals to move between the textile layers. By integrating storytelling into the concept a design brief emerged. However, during the development of the first concept, the design brief missed focus, leading to more complex ideas. Emphasizing communication, the focus shifted to conveying how spectral tuning can influence depth perception in the current setup. This resulted in the emergence of concept 2 with a simplified design involving two layers of textile and a projector.

A preliminary test of concept 2 revealed a need for additional information to enhance understanding and appreciation. The addition of an illustrative introduction before experiencing the installation, significantly improved attributes such as perceived depth, beauty, immersion, engagement, and coherence. These insights guided refinements in the final design, including a shortened visual narrative, added audio for increased engagement, and an elaborate exhibition space design. Attention was consistently committed to communication at various levels.

A final validation test produced varied results but consistently high scores on every attribute. Feedback and recommendations from the test were wellreceived, eliminating ambiguities. Even individuals outside the test expressed enjoyment of the experience. Despite the project’s initially broad scope, a focused approach, particularly in communication, developed in a final design that communicates clearly and evokes joy and interest in viewers.
