AUGMENT HOLOLENS‟ BODY RECOGNITION AND TRACKING CAPABILITIES USING KINECT. In this thesis, we are primarily interested in exploring the HoloLens technologies for medical practices. Particularly, we will address the limitation of HoloLens‟ capability in human body sensing, recognition and tracking. We will then introduce and demonstrate the use of Kinect to augment HoloLens‟ sensory and processing capabilities in order to produce time and space-synchronized immersive environment with both virtual body and real body of the same patient for supporting distributed medical collaborations. Specifically, we are looking at a distributed solution in which we are collecting the patient body data from Kinect, followed by body recognition and position/motion tracking processing at a server; Then we will display and align the virtual body object, composed based on the Kinect-obtained patient body or body part position information, with the real patient body in the doctor‟s augmented reality environment using HoloLens. We have implemented a prototype system to illustrate the distributed solution. Our experimental results using the prototype system demonstrate successful data flow and workflows. This results in effective time and space-synchronizations between the virtual and real bodies in the augmented reality environment. III Through the prototype system, we can track movement, e.g., an arm, in all directions by the Kinect and the coordinates will be sent to HoloLens through which we will augment the real body with a virtual meshed body composed from Kinect-collected data. We have demonstrated that the solution and prototype can effectively address related limitations of HoloLens, and successfully present in real-time the movement of a recognized subject in the form of both virtual and real world human body, and aligned with each other. We believe this work has helped lay a solid foundation for future works to build complete virtual human atlas into the AR views, which may potentially assist surgeons with context-aware guidance by displaying him/her the instructions and feeding him with only the closely associated information through the course of operation. This distributed collaborative solution is of particular advantage for doctors to master faster and more safely advanced and complicated surgical techniques, like using advanced radiation therapy system for cancer treatments by eliminating the physical barriers such as distance, space, resource.

  • Samsung Announces New Windows-Based Virtual-Reality Headset at Microsoft Event 4 October 2017, by Matt Day, the Seattle Times
    Samsung announces new Windows-based virtual-reality headset at Microsoft event 4 October 2017, by Matt Day, The Seattle Times Samsung is joining Microsoft's virtual reality push, Microsoft also said that it had acquired AltspaceVR, announcing an immersive headset that pairs with a California virtual reality software startup that was Windows computers. building social and communications tools until it ran into funding problems earlier this year. The Korean electronics giant unveiled its Samsung HMD Odyssey at a Microsoft event in San ©2017 The Seattle Times Francisco recently. It will sell for $499. Distributed by Tribune Content Agency, LLC. The device joins Windows-based immersive headsets built by Lenovo, HP, Acer and Dell, and aimed for release later this year. Microsoft is among the companies seeking a slice of the emerging market for modern head-mounted devices. High-end headsets, like Facebook-owned Oculus's Rift and the HTC Vive, require powerful Windows PCs to run. Others, including the Samsung Gear VR and Google's Daydream, are aimed at the wider audience of people who use smartphones. Microsoft's vision, for now, is tied to the PC, and specifically new features in the Windows operating system designed to make it easier to build and display immersive environments. The company also has its own hardware, but that hasn't been on display recently. Microsoft's HoloLens was a trailblazer when it was unveiled in 2015. The headset, whose visor shows computer-generated images projected onto objects in the wearer's environment without obscuring the view of the real world completely, was subsequently offered for sale to developers and businesses.

Evaluating the Microsoft oloLeH ns through an augmented reality assembly application Abstract Industry and academia have repeatedly demonstrated the transformative potential of Augmented Reality (AR) guided assembly instructions. In the past, however, computational and hardware limitations often dictated that these systems were deployed on tablets or other cumbersome devices. Often, tablets impede worker progress by diverting a user's hands and attention, forcing them to alternate between the instructions and the assembly process. Head Mounted Displays (HMDs) overcome those diversions by allowing users to view the instructions in a hands-free manner while simultaneously performing an assembly operation.

  • Mixed Reality & Microsoft Hololens
    Mixed Reality & Microsoft HoloLens Laboratorio di Realtà Virtuale Manuel Pezzera – [email protected] Mixed Reality • “Mixed reality (MR) is a spectrum of immersive experiences, connecting and blending physical and digital worlds together in augmented-reality and virtual-reality applications” [cit. Microsoft] Mixed Reality Augmented and Virtual Reality • Virtual Reality: it tricks your eyes into thinking that you are somewhere else. • Augmented reality: it is an extra dimension over VR since it can show the real world around wearer with graphic overlayed. • AR can also totally immerse user just like VR by simply showing pixels everywhere with no transparency to the real world. • In virtual world, users are best advised to stay seated to avoid collision with physical objects which they cannot see in the real world. What is a hologram? • A hologram is an object like any other object in the real world, with only one difference: instead of being made of physical matter, a hologram is made entirely of light. • Holographic objects can be viewed from different angles and distances, just like physical objects. They can also interact with the environment (e.g., bouncing ball on a table) • Hologram do not offer any physical resistance when touched or pushed because they don’t have a mass. Mixed reality vs Augmented Reality • MR can be mentioned as an enhanced form of Augmented Reality (AR). In AR the visible natural environment is overlaid with a layer of digital content. • But the case is slightly different with MR, as virtual objects are integrated into and responsive to the real world. For instance, a virtual ball under your desk would be blocked from a user’s view unless he bends.
