TL;DR
DuoZone is a mixed-initiative XR window management system that combines user-defined spatial layouts with LLM-guided automation to improve productivity and reduce cognitive load in mixed reality environments.
Contribution
We introduce DuoZone, a novel dual-zone system that integrates high-level automation with precise manual control for XR window management.
Findings
DuoZone improves task completion speed in XR environments.
Users experience reduced mental effort with DuoZone.
DuoZone increases users' sense of control during multi-application tasks.
Abstract
Mixed reality (XR) environments offer vast spatial possibilities, but current window management systems require users to manually place, resize, and organize multiple applications across large 3D spaces. This creates cognitive and interaction burdens that limit productivity. We introduce DuoZone, a mixed-initiative XR window management system that combines user-defined spatial layouts with LLM-guided automation. DuoZone separates window management into two complementary zones. The Recommendation Zone enables fast setup by providing spatial layout templates and automatically recommending relevant applications based on user tasks and high-level goals expressed through voice or text. The Arrangement Zone supports precise refinement through direct manipulation, allowing users to adjust windows using natural spatial actions such as dragging, resizing, and snapping. Through this dual-zone…
