Tangible and Visible 3D Object Reconstruction in Augmented Reality

Evaluating Mixed and Augmented Reality: A Systematic Literature Review (2009-2019)

“…Consequently, we ask how we can bridge technology-centric and human-centric evaluations when this combination helps address a research question. In fact, we have observed some papers that followed such pattern [14,39,41,54,68,93,96,104,109,116,117]. We call researchers in the field to complement the results of benchmarks with user studies when techniques involve a user interface and the combination of evaluations contributes to the research question at hand.…”

A Classification of Augmented Reality Approaches for Spatial Data Visualization

“…Changes in point of view might provide new information, but nonetheless the entirety of the virtual object can be perceived from a single point of view. Examples of this category are found in 3D object reconstruction [44] and in paper map enhancement via AR [1].…”

“…AR visualizations presented at the same scale (Figure 2b) are at a 1:1 scale to the source, meaning they are presented without size change to the viewer. Instances of this category are found for example in 3D object reconstruction [44] where the reconstructed object is presented overlaid over the source (real-world) object, and urban AR approaches [17,31] where data about the urban environment is overlaid over the urban environment itself.…”

“…The classification axes presented in this paper are considered independent of each other, meaning that AR applications can be described by any combination of axis categories, without significant limitations between axes. For example, work presented in both [44] and [1] is smaller than human size in terms of visualization size, however [44] presents virtual objects in 1:1 scale while [1] presents virtual objects in small scale. At the same time, while both [44] and [31] present virtual objects at 1:1 scale, the former is presented in smaller than human size, the latter at larger than human size.…”

Mixed Reality Interaction Techniques

“…fiducials have to be simply printed out and attached to objects), these markers can inhibit interaction due to their susceptibility to occlusions (typically through hand and finger interaction). Hence, it is advised to use modern approaches for hand-based interaction [16,203] with spatially tracked rigid and non-rigid objects [141,259,346]. Also, when using OST HMDs, the calibration between the HMD and the users' eyes can impact the interaction [120,134].…”
