In this paper we review the limitations of existing theories in explaining cybersickness and propose a practical alternative approach. We start by providing a clear operational definition of provocative motion stimulation during active HMD VR. In this situation, whenever the user makes a head movement, his/her virtual head will tend to trail its true position and orientation due to the display lag (or motion to photon latency). Importantly, these differences in virtual and physical head pose (DVP) will vary over time. -

M&A @ Facebook: Strategy, Themes and Drivers
A Work Project, presented as part of the requirements for the Award of a Master Degree in Finance from NOVA – School of Business and Economics M&A @ FACEBOOK: STRATEGY, THEMES AND DRIVERS TOMÁS BRANCO GONÇALVES STUDENT NUMBER 3200 A Project carried out on the Masters in Finance Program, under the supervision of: Professor Pedro Carvalho January 2018 Abstract Most deals are motivated by the recognition of a strategic threat or opportunity in the firm’s competitive arena. These deals seek to improve the firm’s competitive position or even obtain resources and new capabilities that are vital to future prosperity, and improve the firm’s agility. The purpose of this work project is to make an analysis on Facebook’s acquisitions’ strategy going through the key acquisitions in the company’s history. More than understanding the economics of its most relevant acquisitions, the main research is aimed at understanding the strategic view and key drivers behind them, and trying to set a pattern through hypotheses testing, always bearing in mind the following question: Why does Facebook acquire emerging companies instead of replicating their key success factors? Keywords Facebook; Acquisitions; Strategy; M&A Drivers “The biggest risk is not taking any risk... In a world that is changing really quickly, the only strategy that is guaranteed to fail is not taking risks.” Mark Zuckerberg, founder and CEO of Facebook 2 Literature Review M&A activity has had peaks throughout the course of history and different key industry-related drivers triggered that same activity (Sudarsanam, 2003). Historically, the appearance of the first mergers and acquisitions coincides with the existence of the first companies and, since then, in the US market, there have been five major waves of M&A activity (as summarized by T.J.A. -

Instructions on Using VR Oculus Rift S
Instructions on Using VR Oculus Rift S Turn on the VR Computer. Login as usual. No password is set. If it is not already connected, connect the end of the cable (two connections) of the Oculus Rift S VR headset to the computer. One end will be a USB cable and the other will be a Display Port cable to the back of the computer. On the computer:- • Click and launch the Oculus software program. • The Oculus software programme screen once launched should look similar to below. • The devices may already be paired. But if starting fresh - Click on Devices on the left menu. • Click on right pointing arrow beside Rift S under listing of devices. • Follow steps to confirm connection. • Click on the right pointing arrow for Left and Right Touch to setup controllers. • To pair left controller :– o Press and hold the Menu and ‘Y’ button until the status light starts blinking. You will also feel a slight vibration to indicate pairing. Page 1 of 4 • To pair right controller :– o Repeat above step but press and hold Oculus icon and ‘B’ button. o Once paired you will get a green tick to indicate pairing successful. Wearing the VR Headset • Before you wear your Oculus Rift S headset with glasses, check to make sure that the width and height of your frames are as follows: o Width: 142 mm or less. o Height: 50 mm or less. Note: If your glasses don't fit in the headset or the lenses of your glasses touch the Rift S lens, Oculus recommend taking off your glasses while using Rift S. -

Virtual Reality Tremor Reduction in Parkinson's Disease

Njie, NeuroStorm, Inc, 1412 Broadway, Fl21, New York, NY 10018. Tel.: +1 347 651 1267; [email protected], [email protected] Abstract: Multidisciplinary neurotechnology holds the promise of understanding and non-invasively treating neurodegenerative diseases. In this preclinical trial on Parkinson's disease (PD), we combined neuroscience together with the nascent field of medical virtual reality and generated several important observations. First, we established the Oculus Rift virtual reality system as a potent measurement device for parkinsonian involuntary hand tremors (IHT). Interestingly, we determined changes in rotation were the most sensitive marker of PD IHT. Secondly, we determined parkinsonian tremors can be abolished in VR with algorithms that remove tremors from patients' digital hands. We also found that PD patients were interested in and were readily able to use VR hardware and software. Together these data suggest PD patients can enter VR and be asymptotic of PD IHT. Importantly, VR is an open-medium where patients can perform actions, activities, and functions that positively impact their real lives - for instance, one can sign tax return documents in VR and have them printed on real paper or directly e-sign via internet to government tax agencies. -
Using Virtual Reality to Engage and Instruct: a Novel Tool for Outreach and Extension Age Group: All Ages! Dr. Geoffrey Attardo
Using Virtual Reality to Engage and Instruct: A novel tool for Outreach and Extension Age Group: All Ages! Dr. Geoffrey Attardo Email: [email protected] Assistant Professor Room 37 Briggs Hall Department of Entomology and Nematology University of California, Davis Davis, California 95616 Recent developments in computer and display technologies are providing novel ways to interact with information. One of these innovations is the development of Virtual Reality (VR) hardware. Innovations in hardware and software have made this technology broadly accessible with options ranging from cell phone based VR kits made of cardboard to dedicated headsets driven by computers using powerful graphical hardware. VR based educational experiences provide opportunities to present content in a form where they are experienced in 3 dimensions and are interactive. This is accomplished by placing users in virtual spaces with content of interest and allows for natural interactions where users can physically move within the space and use their hands to directly manipulate/experience content. VR also reduces the impact of external sensory distractions by completely immersing the user in the experience. These interactions are particularly compelling when content that is only observable through a microscope (or not at all) can be made large allowing the user to experience these things at scale. This has great potential for entomological education and outreach as students can experience animated models of insects and arthropods at impossible scales. VR has great potential as a new way to present entomological content including aspects of morphology, physiology, behavior and other aspects of insect biology. This demonstration allows users of all ages to view static and animated 3D models of insects and arthropods in virtual reality. -

Laser Scanning for Bim and Results Visualization Using Vr

Pavelka, jr.1, B. Michalík 2 1 Czech Technical University in Prague, Faculty of Civil Engineering, dept. of Geomatics, Thakurova 7, Prague 6,16629 [email protected] 2 G4D s.r.o., Prague, Czech Republic, Hauptova 594 156 00 Praha 5-Zbraslav, Czech Republic, [email protected] KEY WORDS: Virtual reality, photogrammetry, laser scanning, BIM, documentation ABSTRACT: Virtual Reality (VR) is a highly topical subject in many branches of science and industry. Thanks to the rapid development and advancement of computer technology in recent years, it can now be used to a large extent, with more detail to show and is now more affordable than before. The use of virtual reality is currently devoted to many disciplines and it can be expected that its popularity will grow progressively over the next few years. The Laboratory of Photogrammetry at the Czech Technical University in Prague is also interested in VR and focuses mainly on documentation and visualization of historical buildings and objects. Our opinion is that in the field of virtual reality there is great potential and extensive possibilities. 3D models of historical objects, primarily created by photogrammetric IBRM technology (image based modelling and rendering) or by laser scanning, gain a completely different perspective in VR. In general, most of the newly designed buildings are now being implemented into BIM.
