    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.

  • Neural Networks on Microsoft Hololens 2
    Institute of Parallel and Distributed Systems University of Stuttgart Universitätsstraße 38 D–70569 Stuttgart Bachelor Thesis Neural Networks on Microsoft HoloLens 2 Léon Lazar Course of Study: Informatik (Computer Science) Examiner: Prof. Dr. rer. nat. Dr. h. c. Kurt Rothermel Supervisor: Johannes Kässinger, M.Sc. Commenced: November 5, 2020 Completed: May 5, 2021 Abstract The goal of the present Bachelor thesis is to enable comparing different approaches of integrating Neural Networks in HoloLens 2 applications in a quantitative and qualitative manner by defining highly diagnostic criteria. Moreover, multiple different approaches to accomplish the integration are proposed, implemented and evaluated using the aforementioned criteria. Finally, the work gives an expressive overview of all working approaches. The basic requirements are that Neural Networks trained by TensorFlow/Keras can be used and executed directly on the HoloLens 2 without requiring an internet connection. Furthermore, the Neural Networks have to be integrable in Mixed/Augmented Reality applications. In total four approaches are proposed: TensorFlow.js, Unity Barracuda, TensorFlow.NET, and Windows Machine Learning which is an already existing approach. For each working approach a benchmarking application is developed which runs a common reference model on a test datatset to measure inference time and accuracy. Moreover, a small proof of concept application is developed in order to show that the approach also works with real Augmented Reality applications. The application uses a MobileNetV2 model to classify image frames coming from the webcam and displays the results to the user. All the feasible approaches are evaluated using the aforementioned evaluation criteria which include ease of implementation, performance, accuracy, compatibility with Machine Learning frameworks and pre-trained models, and integrability with 3D frameworks.

  • Validity of Hololens Augmented Reality Head Mounted Display for Measuring Gait Parameters in Healthy Adults and Children with Cerebral Palsy
    sensors Article Validity of Hololens Augmented Reality Head Mounted Display for Measuring Gait Parameters in Healthy Adults and Children with Cerebral Palsy Anne-Laure Guinet 1,2,* , Guillaume Bouyer 2 , Samir Otmane 2 and Eric Desailly 1 1 Pôle Recherche & Innovation, Fondation Ellen Poidatz, 77310 Saint-Fargeau-Ponthierry, France; [email protected] 2 IBISC Lab, University Paris-Saclay, University Evry, 91020 Evry, France; [email protected] (G.B.); [email protected] (S.O.) * Correspondence: [email protected] Abstract: Serious games are a promising approach to improve gait rehabilitation for people with gait disorders. Combined with wearable augmented reality headset, serious games for gait rehabilitation in a clinical setting can be envisaged, allowing to evolve in a real environment and provide fun and feedback to enhance patient’s motivation. This requires a method to obtain accurate information on the spatiotemporal gait parameters of the playing patient. To this end, we propose a new algorithm called HoloStep that computes spatiotemporal gait parameters using only the head pose provided by an augmented reality headset (Hololens). It is based on the detection of peaks associated to initial contact event, and uses a combination of locking distance, locking time, peak amplitude detection with custom thresholds for children with CP. The performance of HoloStep was compared during a walking session at comfortable speed to Zeni’s reference algorithm, which is based on kinematics Citation: Guinet, A.-L.; Bouyer, G.; and a full 3D motion capture system. Our study included 62 children with cerebral palsy (CP), Otmane, S.; Desailly, E.
