AR-Loupe: Magnified Augmented Reality by Combining an Optical See-Through Head-Mounted Display and a Loupe.
IEEE transactions on visualization and computer graphics, 2020Co-Authors: Long Qian, Tianyu Song, Mathias Unberath, Peter KazanzidesAbstract:Head-mounted Loupes can increase the user's visual acuity to observe the details of an object. On the other hand, optical see-through head-mounted displays (OST-HMD) are able to provide virtual augmentations registered with real objects. In this paper, we propose AR-Loupe, combining the advantages of Loupes and OST-HMDs, to offer augmented reality in the user's magnified field-of-vision. Specifically, AR-Loupe integrates a commercial OST-HMD, Magic Leap One, and binocular Galilean magnifying Loupes, with customized 3D-printed attachments. We model the combination of user's eye, screen of OST-HMD, and the optical Loupe as a pinhole camera. The calibration of AR-Loupe involves interactive view segmentation and an adapted version of stereo single point active alignment method (Stereo-SPAAM). We conducted a two-phase multi-user study to evaluate AR-Loupe. The users were able to achieve sub-millimeter accuracy (0.82mm) on average, which is significantly (p

The users were able to achieve sub-millimeter accuracy (0.82mm) on average, which is significantly (p<0.001) smaller compared to normal AR guidance (1.49mm). The mean calibration time was 268.46s. With the increased size of real objects through optical magnification and the registered augmentation, AR-Loupe can aid users in high-precision tasks with better visual acuity and higher accuracy.

Precision of suture placement with microscope‐ and Loupe‐assisted anastomoses
Microsurgery, 1993Co-Authors: Michael D. Rooks, Joseph Slappey, Kathy ZusmanisAbstract:Twenty-eight anastomoses involving seven surgeons were done on 2 mm Gortex vascular prostheses to test the effect of magnification on the precision of suture placement. One-half were done with 3.5-4 × prism Loupe magnification and the other one-half with 8-30 × microscope magnification. The variability of suture placement (defined here as precision) was measured in a blinded fashion. The mean suture puncture to prosthesis edge measurement for the microscope-assisted group was ∼ 0.03 mm closer to the edge. The variability from the mean for the microscope-assisted group was ∼ 0.01 mm less than that for the Loupe-assisted group. This difference was statistically significant at a P value of 0.0123. © 1993 Wiley-Liss Inc.
