2.2 Spatial analysis

In the design concept we had decided to have the interactivity responsive to sound. The next challenge was to define, what kind of response we wanted to have, and how should the sensors be organized. The options varied from having only one sensor in the end of the tunnel to having several sensors in close intervals along the length of the tunnel. Due to the complexity of intelligent lighting design installations, this part of the design has stayed more in the level of ideation, and only a small and simple interactive experiment was carried out. The experiment was conducted with help of a Seeeduino microcontroller, a Grove sound sensor, and an addressable RGB LED strip and the scale model, studying different kinds of animated light scenarios. The experiment with the animated lighting scenarios ended in the conclusion, that many of the animated scenarios were simply too flashy and would demand a lot of attention from the user. As most people use the tunnel for ordinary commuting rather than to experience something extravagant, we put attention in making sure that, whatever the effect was, it would not give too much new symbolic meaning to the light and that the final design would stay subtle.

SUMMARY: The design experiments provided valuable insights into shaping the design concept into a final design. During the experiments, the specifications for the pools of light and interactive train tracks were formulated.

4.3 Final design

This chapter is a visual depiction of the final design, which has been envisioned after revisiting the findings from chapters 3 and 4 and visualized through TwinMotion renderings and graphical diagrams. A user journey through the tunnel from Enghavevej to Otto Bussesvej has first been presented through rendered images, in order to put into context the lighting design proposed and to offer a more extensive view of the complex design. The interactivity system this design is based on is then explained through a procedural diagram, followed by the implementation table of the entire lighting, for a better overview of its elements. Lastly, the key takeaways from the design evaluation done in the old train station (Baanegaarden café and bar) have been presented, which supported and validated our vision.

Enghavevej node

Since the tunnel is currently hidden below eye-level and unnoticeable from Enghavevej, the track lights are spread above its entrance, on the overhead fence and on the concrete wall across from it. In this way, there is a more clear and visually interesting signaling of the path towards the City and out of it.
