Summary: This paper proposes a partially-sorted concentric label layout for Augmented Reality labeling, which increases search efficiency and avoids issues with long or intersecting leader lines. The layout was tested in a user study and significantly reduced label searching time compared to a conventional single-circle layout.

Summary: Land-use maps play a crucial role in urban planning and environmental research. Street view images (SVIs) have shown great potential for automated land-use classification, but previous studies have overlooked the contextual information from SVIs. This study proposes a novel method that synthesizes location semantics from SVIs to improve land-use classification accuracy.

Summary: This study extended the rendering styles of color and size variables in AR geovisualization, and through user experiments, it was found that dynamic variables have higher guidance characteristics than static variables, with shape being one of the most guiding static variables. These results have implications for guiding visual variable selection in symbol design for AR geovisualization.

Summary: Augmented reality (AR) has proven to be efficient in the architecture, engineering, construction and operation (AECO) domain, especially when integrated with building information modeling (BIM). However, the precision and accuracy of placing virtual 3D models in an AR environment can be a challenge. This paper proposes a methodology to evaluate different AR placement methods quantitatively and qualitatively, focusing on their usability in the AECO context. Results show a wide range of placement errors in AR, with marker-based methods performing better than others. Commercial solutions using placement sensors show good performance in manual mode, but lower accuracy and stability in automatic mode.

Summary: Global Positioning Systems (GPS) play a crucial role in navigation, but localizing the exact destination within the last few meters remains unresolved due to GPS limitations. Street view images (SVI) serve as an aid in providing the physical environment for last-meter wayfinding, but distracting objects in SVI can hinder efficient destination locating. To address this, a saliency-guided image inpainting framework is proposed to reduce visual distraction and improve efficient wayfinding in the last meters.

Summary: The study proposes the concept of "Duplicated Reality" to allow users to remotely annotate the working area in AR while being co-located with others. Results from a user study show almost identical objective and subjective outcomes compared to in-situ augmentation, except for a decrease in the consulting user's awareness of co-located users when using the proposed method. The addition of duplicating the working area into a designated consulting area provides new interaction paradigms for future co-located AR collaboration systems.

Summary: This study proposes an effective marker-less image guidance method, which initializes using contour matching and obtains the corresponding relationship by matching feature points between the current and initial frames. The camera pose is estimated by solving the Perspective-n-Point problem. The results show that the registration error of AR images is 0.731 +/- 0.144 mm and the planting errors meet clinical requirements. This method accurately guides dentists in dental implant surgeries.

Summary: AR and VR can provide cues and precues to assist users in completing manual tasks more efficiently. Previous research has focused on simple tasks, but we examined a more complex task and found that providing continuous movement information and single rotation information yielded the best results through two user studies.

Summary: AR-guided surgery demonstrated a 100% accuracy rate for the insertion of 63 percutaneous pedicle screws in 9 patients (100% rate of Gertzbein-Robbins grade A or B screw placement), showing promising potential for future applications. Further validation with larger cohorts of patients across multiple surgeons and institutions is needed to determine the full extent of the technology's accuracy.

Summary: In this paper, a fully automated georegistration method for wide-area 3D data generation in complex urban environments is proposed. The method utilizes semantically segmented object boundaries as view invariant features and performs registration through graph-matching. The experiment shows promising results on a large-scale cross-view dataset.
