“…Virtual annotations, such as labels, images, and some other ways, were often used to annotate physical objects. Displaying annotations by aid of AR may have better effects on the user's memory skill, if they are associated with the location of the target object on the real world [14]. Therefore, the layout of virtual annotations was one of the key techniques in this kind of AR applications.…”

In augmented reality (AR)-based assembly and disassembly guiding systems, the guiding effects mainly depend on display characters of virtual guiding scene. If the virtual guiding scene is not displayed properly, such as displaying out of the operator's view, overlaying on the interest region of the screen, selecting an inappropriate viewpoint of the three-dimensional (3D) guiding scene, and so on, it may disturb normal operation instead of guiding. To display the 3D virtual guiding scene on suitable screen region from a comfortable viewpoint, an adaptive guiding scene display method was proposed. In the adaptive selection of the display region, the display screen was divided into many grids. The screen projection coordinates for vertexes of CAD feature's bounding boxes, and the occupied index of each grid was calculated. The maximum connected region of empty grids was chosen as a non-interest region on the screen for displaying the 3D guiding scene. In the optimal viewpoint selection algorithm, a viewpoint information measurement operator was put forward, which took projection area, visible proportion, information entropy, and difference in depth of all visible vertexes of CAD feature's bounding box in 3D virtual guiding scene into account. Finally, based on the principle of perspective projection, the 3D virtual guiding scene was positioned into the virtual world and displayed from the specified viewpoint on the specified screen area. All algorithms proposed in this paper utilized the automatically extracted CAD feature's bounding box model of part as input data so they could be implemented for online planning of 3D assembly guiding scenes.

“…As a first step, we conducted a user study in [5], and we verified that displaying annotations using AR can enhance a user's memory * e-mail: {yuichiro-f, goshiro, takafumi-t, miyazaki, kato} @is.naist.jp skill in a task in which users are instructed to memorize individual symbols, if the annotations are displayed near the real-world location of the target object instead of an unrelated location. In this paper, we conducted another user study in which users were instructed to memorize continuous task processes of more realistic tasks, by picking blocks from some drawers in order to evaluate the relation between the features of AR and user memorization.…”

The objective of this study is to investigate the relationship between the features of augmented reality (AR) and human memorization ability. The basis of this relation is derived from the following features. The AR feature is that AR can provide information associated with specific locations in the real world. The feature of human memory is that humans can easily memorize information if the information is visually associated with specific locations. To investigate this relation, we conduct a pilot user study in which blocks are picked from some drawers. As a result, significant differences are found between a situation in which visual information is displayed at the location of each drawer in the real world and that in which textual information is displayed at an unrelated location.

“…They hypothesize that this difference may be due to the kinetic component of moving the projector. Fujimoto et al [8] studied the effect of adding visual cues on targets to be memorized using an HMD system. They found that associating visual anotations with real world locations enhances the learning.…”

Various guidance techniques have been proposed to help users to quickly and effectively locate objects in large and dense environments such as supermarkets, libraries, or control rooms. Little research, however, has focused on their impact on learning. These techniques generally transfer control from the user to the system, making the user more passive and reducing kinesthetic feedback. In this paper, we present an experiment that evaluates the impact of projection-based guidance techniques on spatial memorization. We investigate the roles of user (handheld) vs. system control (robotic arm) guidance and of kinesthetic feedback on memorization. Results show (1) higher recall rates with system-controlled guidance, (2) no significant influence of kinesthetic feedback on recall under system control, and (3) the visibility and noticeability of objects impact memorization.
