Wearable augmented reality (AR) represents the next interface to all things computing, extending what smartphones and laptops can do. This involves providing access to digital information during activities like walking or jogging. In this work we argue that the impact of physical movement on AR interaction is not direct, but mediated by UI placement - the spatial relationship between the user and the interface. Current research often treats interaction techniques in isolation, overlooking how their performance is fundamentally linked to where the UI is placed. This position paper highlights the need to reconceptualize UI placement beyond traditional anchoring views, explore novel interaction techniques designed for specific UI placements during locomotion, and rigorously evaluate UI placement as an independent variable in experimental studies. By centering the analysis on the relative movement between user and interface, we can unlock more effective on-the-go AR interaction.
