Exploring Interactions with Smart Windows for Sunlight Control
Patrick Bader, Huy Viet Le, Julian Strotzer, Niels Henze · 2017
Window facades play an increasingly important role in modern architecture. Regular shutters and blinds allow only coarse control over the sunlight coming through windows. Smart windows using see-through displays can be controlled on a per-pixel basis and thereby have the potential of fine-grained control. In this paper, we explore future interaction with such smart windows and conducted an elicitation study with 16 potential users. We provide both a mid-air gesture set and a smartphone interface to define regions for glare protection and brightness control. The study was conducted on a working 1.6 x 2.6 m smart window prototype with 130 x 144 individually switchable pixels.
