Understanding Window Management Interactions in AR Headset + Smartphone Interface

We envision a combinative use of an AR headset and a smartphone in the future that can provide a more extensive display and precise touch input simultaneously. In this way, the input/output interface of these two devices can fuse to redefine how a user can manage application windows seamlessly on the two devices. In this work, we conducted a formative interview with ten people to provide an understanding of how users would prefer to manage multiple windows on the fused interface. Our interview highlighted that the desire to use a smartphone as a window management interface shaped users' interaction practices of window management operations. This paper reports how their desire to use a smartphone as a window manager is manifested.
