“…The research at UCLA focuses on Augmented Reality (AR) in the context on radiation oncology together with GPU-based processing for clinical translation, while the satellite lab in Armstrong Atlantic University focuses on undergraduate and master education in augmented reality, wth a focus on haptic and networking AR. The research in the headquarter lab focused early on solely on novel head-worn displays for AR [59][60][61]. The ODALab conducted some of the first depth perception studies in AR environments published in the Journal Presence: Teleoperators and Virtual Environments (MIT Press) [62][63][64].…”

We present our efforts in establishing a Research Pole in Photonics in the future Arad-Timisoara metropolitan area projected to unite two major cities of Western Romania. Research objectives and related training activities of various institutions and groups that are involved are presented in their evolution during the last decade. The multi-disciplinary consortium consists principally of two universities, UAVA (Aurel Vlaicu University of Arad) and UMF (Victor Babes Medicine and Pharmacy University of Timisoara), but also of the Arad County Emergency University Hospital and several innovative SMEs, such as Bioclinica S.A. (the largest array of medical analysis labs in the region) and Inteliform S.R.L. (a competitive SME focused on mechatronics and mechanical engineering). A brief survey of the individual and joint projects of these institutions is presented, together with their teaching activities at graduate and undergraduate level. The research Pole collaborates in R&D, training and education in biomedical imaging with universities in USA and Europe. Collaborative activities, mainly on Optical Coherence Tomography (OCT) projects are presented in a multidisciplinary approach that includes optomechatronics, precision mechanics and optics, dentistry, medicine, and biology.

“…The HMD was equipped with wide field of view (FOV) optics (LEEP Pop-Optix,Waltham, MA). Inverse lenses (also made by LEEP), which correct for the optical distortion in the HMD's optics [12], were mounted on the platform cameras. The HMD had a 75 horizontal by 60 vertical FOV across the center axis of each eye with a combined binocular horizontal FOV of 90 [12].…”

The HMD had a 75 horizontal by 60 vertical FOV across the center axis of each eye with a combined binocular horizontal FOV of 90 [12]. This horizontal and vertical FOV, however, is reduced at oblique viewing angles by the vignetting of the HMD lenses' cutout shape and underlying LCD mask.…”

Rotation and Direction Judgment from Visual Images Head-Slaved in Two and Three Degrees-of-Freedom Bernard D. Adelstein and Stephen R. EllisAbstract-The contribution to spatial awareness of adding a roll degree-of-freedom (DOF) to telepresence camera platform yaw and pitch was examined in an experiment where subjects judged direction and rotation of stationary target markers in a remote scene. Subjects viewed the scene via head-slaved camera images in a head-mounted display. Elimination of the roll DOF affected rotation judgment, but only at extreme yaw and pitch combinations, and did not affect azimuth and elevation judgment. Systematic azimuth overshoot occurred regardless of roll condition. Observed rotation misjudgments are explained by kinematic models for eye-head direction of gaze.

“…When considering the computer simulated images, a pre-distortion correction can be applied to them in order for the projected image through the LEEP optics to appear unwarped (Robinett and Rolland, 1992). The same cannot be done on the acquired video images using our current setup because of the direct output of the video signals to the LCDs.…”

“…This can be theoretically accomplished using a 45" folding mirror per eye as shown in Figure 1. For a horizontal FOV of 75", which is the LEEP optics' and video camera's FOV, a 530" x 540" mirror is then required (Robinett and Rolland, 1992); however, for stereo HMDs, the size of this mirror is impractical and also usable for only one eye. Vertically mounted camera arrangements yield similar, bulky packages.…”

Video see-through design for merging of real and virtual environments

A head mounted display (HMD) that is optically opaque with respect to the outer world can be provided with see-through capability by mounting video cameras to the outside of the helmet. Stereoscopic views of the physical space surrounding the wearer are captured by the video cameras and are projected to the display screens inside the HMD. In this paper, the authors describe the conditions necessary for mounting the cameras to a pre-existing, non-see-through HMD before discussing the advantages and disadvantages of different mounting schemes. We finally describe the design of the video cameras lenses to be used with this specific application.
