Squama: The Programmable Physical Window of the Future

Revolutionizing Architecture with Jun Rekimoto & Akihito Kinoshita

Squama, designed by Jun Rekimoto and Akihito Kinoshita, is a groundbreaking innovation in the world of architecture. Inspired by the adaptability of nature, Squama is a programmable physical window or wall that can independently control the transparency of its elemental area, revolutionizing the way we interact with our built environment.

One of the key strengths of Squama is its ability to dynamically control transparency, making it an ideal solution for both openness and privacy. When used as a wall, Squama can adjust its surface transparency to meet the needs of the occupants, providing a balance between visibility and seclusion. Additionally, Squama can control the amount of sunlight entering a space, creating programmable shadows that enhance indoor comfort without completely blocking the outer view.

The technology behind Squama is a combination of Transmart LCD material developed by Asahi Glass and a custom control circuit. Each Squama cell measures 45mmx45mm, and the window module size ranges from 540mmx1620mm to 4320mmx1620mm, depending on the number of cells.

Interactivity is at the core of Squama's design. The individual cells can be independently controlled to change their transparency, allowing for a range of applications. Squama can serve as an ambient information display, showcasing low-resolution patterns, characters, and animations. It can also be used for privacy control by detecting human positions and adjusting transparency accordingly. Furthermore, Squama enables precise lighting control by defining areas to be darkened and calculating the direction of sunlight.

The development of Squama was not without its challenges. Realizing programmable transparency modules as a form for a transparent window itself required careful consideration of electricity control for each cell. Additionally, the design team faced the task of inventing new interaction applications for Squama, pushing the boundaries of what was possible with this innovative technology.

Since its inception in 2012, Squama has garnered recognition and acclaim. In 2016, it was awarded the Silver A' Design Award in the Building Materials and Construction Components category. This prestigious award is a testament to the exceptional creativity, technical expertise, and innovation demonstrated by Squama.

Squama is a glimpse into the future of architecture, where physical elements can adapt and transform to meet the needs of individuals and communities. With its programmable transparency and ability to create programmable shadows, Squama is poised to revolutionize the way we experience and interact with our built environment.
