Base game Manual V0.4 Environment Remove any objects in the playing area that you might touch or hit while playing with your body. Please also make sure that lamps or fans are not in the playing area. If you are at the edge of the playing area, do not make any big movements, otherwise you could touch the walls with your body or hands/controllers. It is best to stand. Step movements are not necessary during the game. You can move and rotate completely with the controllers. Technical requirements To play the game, you need Virtual Reality headset (VR headset). Without VR glasses, the game will not run. A (free) Steam account is also required. Also installed must be the VR software "SteamVR" (when using HTC VIVE or the Valve Index) or the additional software "Windows Mixed Reality for SteamVR" for the use of Windows Mixed Reality glasses on Steam with "SteamVR". Before the first launch, a room measuring should also have been done in SteamVR (when using the HTC VIVE or the Valve Index). When using Windows Mixed Reality glasses, there is an option to change the position of the floor from the height. The controllers of the VR headset should also be connected to the VR system and be charged. The game Container You start the game in the container and go to the selected construction site through the door. Later, you can start different locations here depending on the existing DLC. You can now set options to one of the boards by moving the switch accordingly. -

Virtual Reality Headsets
VIRTUAL REALITY HEADSETS LILY CHIANG VR HISTORY • Many companies (Virtuality, Sega, Atari, Sony) jumped on the VR hype in the 1990s; but commercialization flopped because both hardware and software failed to deliver on the promised VR vision. • Any use of the VR devices in the 2000s was limited to the military, aviation, and medical industry for simulation and training. • VR hype resurged after Oculus successful KickStarter campaign; subsequently acquired by Facebook for $2.4 bn. • Investments rushed into the VR industry as major tech firms such as Google, Samsung, and Microsoft and prominent VC firms bet big on the VR revolution.

Attitudes Towards Virtual Reality Gaming and Products
ATTITUDES TOWARDS VIRTUAL REALITY GAMING AND PRODUCTS Eppu Siirtola International Business Bachelor's Thesis Supervisor: Suzanne Altobello Date of approval: 9 April 2018 Aalto University School of Business Bachelor´s Program in International Business Mikkeli Campus ATTITUDES TOWARDS VIRTUAL REALITY GAMING AND PRODUCTS Eppu Siirtola International Business Bachelor's Thesis Supervisor: Suzanne Altobello Date of approval: 9 April 2018 Aalto University School of Business Bachelor´s Program in International Business Mikkeli Campus AALTO UNIVERSITY ABSTRACT OF SCHOOL OF BUSINESS BACHELOR’S THESIS Mikkeli Campus Author: Eppu Siirtola Title of thesis: ATTITUDES TOWARDS VIRTUAL REALITY GAMING AND PRODUCTS Date: 9 April 2018 Degree: Bachelor of Science in Economics and Business Administration Supervisor: Suzanne Altobello Objectives The main objective of this study was to explore the attitudes towards virtual reality gaming and the products surrounding it to identify the reasons why consumers choose to purchase and adopt the usage of these devices. The study also analyzes the components of added value that virtual reality gaming brings on top of a more traditional gaming experience Summary An extensive examination of already published academic research regarding product adoption and value concept was conducted to realize the key notions that would act as the cornerstones of the primary research. A quantitative survey was designed for the relevant sample to see whether the earlier findings on the topics of product adoption and value concept resonated with the results gathered from the survey focusing on virtual reality gaming and the products surrounding it. Conclusions The research shows that the product adoption in the virtual reality gaming market essentially operates under the already established concepts of product adoption. -
Exploring How Bi-Directional Augmented Reality Gaze Visualisation Influences Co-Located Symmetric Collaboration
ORIGINAL RESEARCH published: 14 June 2021 doi: 10.3389/frvir.2021.697367 Eye See What You See: Exploring How Bi-Directional Augmented Reality Gaze Visualisation Influences Co-Located Symmetric Collaboration Allison Jing*, Kieran May, Gun Lee and Mark Billinghurst Empathic Computing Lab, Australian Research Centre for Interactive and Virtual Environment, STEM, The University of South Australia, Mawson Lakes, SA, Australia Gaze is one of the predominant communication cues and can provide valuable implicit information such as intention or focus when performing collaborative tasks. However, little research has been done on how virtual gaze cues combining spatial and temporal characteristics impact real-life physical tasks during face to face collaboration. In this study, we explore the effect of showing joint gaze interaction in an Augmented Reality (AR) interface by evaluating three bi-directional collaborative (BDC) gaze visualisations with three levels of gaze behaviours. Using three independent tasks, we found that all bi- directional collaborative BDC visualisations are rated significantly better at representing Edited by: joint attention and user intention compared to a non-collaborative (NC) condition, and Parinya Punpongsanon, hence are considered more engaging. The Laser Eye condition, spatially embodied with Osaka University, Japan gaze direction, is perceived significantly more effective as it encourages mutual gaze Reviewed by: awareness with a relatively low mental effort in a less constrained workspace. In addition, Naoya Isoyama, Nara Institute of Science and by offering additional virtual representation that compensates for verbal descriptions and Technology (NAIST), Japan hand pointing, BDC gaze visualisations can encourage more conscious use of gaze cues Thuong Hoang, Deakin University, Australia coupled with deictic references during co-located symmetric collaboration. -
Implementing FPGA Design with the Opencl Standard
Implementing FPGA Design with the OpenCL Standard WP-01173-3.0 White Paper Utilizing the Khronos Group’s OpenCL™ standard on an FPGA may offer significantly higher performance and at much lower power than is available today from hardware architectures such as CPUs, graphics processing units (GPUs), and digital signal processing (DSP) units. In addition, an FPGA-based heterogeneous system (CPU + FPGA) using the OpenCL standard has a significant time-to-market advantage compared to traditional FPGA development using lower level hardware description languages (HDLs) such as Verilog or VHDL. 1 OpenCL and the OpenCL logo are trademarks of Apple Inc. used by permission by Khronos. Introduction The initial era of programmable technologies contained two different extremes of programmability. As illustrated in Figure 1, one extreme was represented by single core CPU and digital signal processing (DSP) units. These devices were programmable using software consisting of a list of instructions to be executed. These instructions were created in a manner that was conceptually sequential to the programmer, although an advanced processor could reorder instructions to extract instruction-level parallelism from these sequential programs at run time. In contrast, the other extreme of programmable technology was represented by the FPGA. These devices are programmed by creating configurable hardware circuits, which execute completely in parallel. A designer using an FPGA is essentially creating a massively- fine-grained parallel application. For many years, these extremes coexisted with each type of programmability being applied to different application domains. However, recent trends in technology scaling have favored technologies that are both programmable and parallel. Figure 1. -
