Overview of our experiment on head-following virtual windows in AR. We manipulated UI type (Head-Locked vs. Tag-Along) and follow-up delay to examine their effects on perceived resistance during horizontal head rotations. Tag-Along windows and longer follow-up delays elicited stronger perceived resistance, while Head-Locked windows produced weaker resistance.

Abstract Augmented Reality (AR) can enhance accessibility by anchoring virtual windows to the user's body. Among common approaches, head-following windows help maintain floating virtual windows within the user's field of view. Previous studies have actively explored this new design space to improve user experience and efficiency. In contrast, this study focuses on the perceived resistance of head-following windows in AR, despite their lack of physical mass. We conducted a within-subject experiment with 24 participants, manipulating follow-up delay, window size, and UI type (Head-Locked vs.\ Tag-Along). We measured subjective resistance ratings, NASA-TLX (Raw TLX Scores), and the gaze--head angular offset. The results showed that both a certain level of follow-up delay and the Tag-Along UI elicited significantly stronger perceived resistance as well as task load. Although window size alone did not show a significant effect on resistance ratings, we observed an interaction between the size and UI type. These findings extend existing pseudo-haptics research by revealing the previously unexplored domain of resistance in head-based interactions with head-following virtual windows. We further provide design implications for head-following windows in AR.
