With this essay I present the fragile thought-image of the soap-bubble to venture an augmented understanding of what an atmospheric ecology might be, what it might include, and how it might contribute to a thinking of interiors. In contemporary digital design the soap-bubble or soap film is most often investigated for what it can tell us about material behaviour, and how an understanding of material behaviour as it occurs in ‘Nature’ can be innovatively applied to design problems. Soap film can be studied in terms of what it tells us about surface tension and minimal distribution of material, which then allows the designer to better understand tensile structures. It also contributes to an understanding of cell walls (from the scale of the microscopic to the macroscopic), and how an interior condition responds to the pressure of an exterior condition. Appropriated from nature through a process of biomimicry the behaviour of soap film and soap-bubbles has been broadly used to test speculative design schemes and also to generate new digital techniques and technologies. I propose to liberate the thought-figure of the soap-bubble from this set of technical studies and applications in order to extend an understanding of how it can be used to frame atmospheric ecologies, especially after the manner in which soap-bubbles cluster and froth. Ecology here must be understood in an expanded sense that encompasses not just naturally occurring systems, championed by special interest groups that fight for a specific environmental niche, but also subjective and social ecologies, and how these different systems remain profoundly intertwined. I draw on the work of Peter Sloterdijk, Jakob Von Uexküll, and also Gregory Bateson to offer other visions of what an atmospheric ecology might be, and how it can offer us more open definitions of the interiors in which we need to find a way to survive.

To experience a real soap bubble show, materials and tools are required, as are skilled performers who produce the show. However, in a virtual space where spatial and temporal constraints do not exist, bubble art can be performed without real materials and tools to give a sense of immersion. For this, the realistic expression of soap bubbles is an interesting topic for virtual reality (VR). However, the current performance of VR soap bubbles is not satisfying the high expectations of users. Therefore, in this study, we propose a physically based approach for reproducing the shape of the bubble by calculating the measured parameters required for bubble modeling and the physical motion of bubbles. In addition, we applied the change in the flow of the surface of the soap bubble measured in practice to the VR rendering. To improve users’ VR experience, we propose that they should experience a bubble show in a VR HMD (Head Mounted Display) environment.

Multiscale sample entropy analysis has been developed to quantify the complexity and the predictability of a time series, originally developed for physiological time series. In this study, the analysis was applied to the turbulence data. We measured time series data for the velocity fluctuation, in either the longitudinal or transverse direction, of turbulent soap film flows at various locations. The research was to assess the feasibility of using the entropy analysis to qualitatively characterize turbulence, without using any conventional energetic analysis of turbulence. The study showed that the application of the entropy analysis to the turbulence data is promising. From the analysis, we successfully captured two important features of the turbulent soap films. It is indicated that the turbulence is anisotropic from the directional disparity. In addition, we observed that the most unpredictable time scale increases with the downstream distance, which is an indication of the decaying turbulence.
