DESIGN NAME: Squama
PRIMARY FUNCTION: Window
INSPIRATION: Squama is an example of programmable physical architecture, our vision for future architectures where the physical features of architectural elements and facades can be dynamically changed and reprogrammed according to people's needs. In a natural world, changing physical feature to adapt environment is common, such as the skin color of Chameleon. We think future architecture should also have such feature, and Squama is the beginning of such.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Squama is a programmable physical window or wall that can independently control the transparency of its elemental area. When Squama is used as a wall, it dynamically controls the transparency through its surface and simultaneously satisfies the needs for openness and privacy. It can also control the amount of sunlight and create shadows, called programmable shadows, in order to afford indoor comfort without completely blocking the outer view.
OPERATION / FLOW / INTERACTION: The squama cell can be independently controlled for changing its transparency. Applications include (1) ambient information display for showing low-resolution patterns / characters / animations (2) Privacy control by detecting human positions, and (3) lighting control by defining place to be darken (i.e., covered with shadow) and calculating the sunlight direction.
PROJECT DURATION AND LOCATION: Started in August 2012 as concept work, the 1st prototype finished in late 2012, and published papers in AVI2013 and video demonstrated at UbiComp2013. The 2nd design is implemented in 2015-2016 with transparent circuit and better LCD material.
FITS BEST INTO CATEGORY: Interface, Interaction and User Experience Design

PRODUCTION / REALIZATION TECHNOLOGY: Transmart LCD Material (Asahi Glass) + custom control circuit
SPECIFICATIONS / TECHNICAL PROPERTIES: Squama cell 45mmx45mm. The window module size is 540mmx1620mm (with 36x24 modular tile cells) to 4320mmx1620mm (with 36x96 cells)

RESEARCH ABSTRACT: -
CHALLENGE: Realizing programmable transparency modules as a form for transparent window itself is challenging, by considering electricity control for each cell. Inventing new interaction applications with this Squama is another challenge.
