The consumer VR market has become a large part of the VR world and is growing at a rapid pace. In spite of this growth, there is no standard controller for VR. This study evaluated three different controllers: a gamepad, the Leap Motion, and a touchpad as means of interacting with a virtual environment (VE). There were 23 participants that performed a matching task while wearing a Samsung Gear VR mobile based VR headset. Measures of performance, preference, presence, and enjoyment were collected and compared across controller. Overall, it was seen that Leap Motions performance effected its other scores and was the least preferred controller. The touchpad resulted in the highest presence scores without notable performance issues. However, the gamepad was the most preferred controller based on its ease of use and pre-established history with users. Based on the results of this study, recommendations for VR companies and developers were made as well as areas of future research to further improve the user experience of consumer VR.

  • A History of Video Game Consoles Introduction the First Generation
    A History of Video Game Consoles By Terry Amick – Gerald Long – James Schell – Gregory Shehan Introduction Today video games are a multibillion dollar industry. They are in practically all American households. They are a major driving force in electronic innovation and development. Though, you would hardly guess this from their modest beginning. The first video games were played on mainframe computers in the 1950s through the 1960s (Winter, n.d.). Arcade games would be the first glimpse for the general public of video games. Magnavox would produce the first home video game console featuring the popular arcade game Pong for the 1972 Christmas Season, released as Tele-Games Pong (Ellis, n.d.). The First Generation Magnavox Odyssey Rushed into production the original game did not even have a microprocessor. Games were selected by using toggle switches. At first sales were poor because people mistakenly believed you needed a Magnavox TV to play the game (GameSpy, n.d., para. 11). By 1975 annual sales had reached 300,000 units (Gamester81, 2012). Other manufacturers copied Pong and began producing their own game consoles, which promptly got them sued for copyright infringement (Barton, & Loguidice, n.d.). The Second Generation Atari 2600 Atari released the 2600 in 1977. Although not the first, the Atari 2600 popularized the use of a microprocessor and game cartridges in video game consoles. The original device had an 8-bit 1.19MHz 6507 microprocessor (“The Atari”, n.d.), two joy sticks, a paddle controller, and two game cartridges. Combat and Pac Man were included with the console. In 2007 the Atari 2600 was inducted into the National Toy Hall of Fame (“National Toy”, n.d.).

  • 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.

  • 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.

  • Play Any PC Game with a Gamepad Using Joytokey for Those Who Prefer Controllers to Keyboards
    Play Any PC Game with a Gamepad Using JoyToKey For those who prefer controllers to keyboards There was a time when “hardcore” PC gamers would look down on the idea of using a gamepad to play PC games. The mouse and keyboard reigned supreme, especially in the golden age of first person shooters. The truth is that joysticks and gamepads have a rich and storied history on the PC, with genres such as racing and flight simulation virtually requiring it to be playable. The problem is that, for a very long time, gamepads on PC were not really standardized. Without a solid idea of what players would be using, many developers simply didn’t bother developing gamepad support for their titles. Now, largely thanks to console ports, the Xbox controller has become the de facto standard for PC gaming too. Better yet, since so many games are also developed for the Xbox, it’s easy for developers to simply include the control scheme. The end result is that if you hook up an Xbox controller to a modern Windows PC, modern games will seamlessly switch over, even changing the in-game UI to reflect gamepad controls. This is the best of time for those of us who love to game with a gamepad on PC, especially from a couch. However, there are thousands of older PC games that only support a keyboard and mouse. Which leaves us with a bit of an issue. Luckily JoyToKey provides an affordable solution. How To Use JoyToKey JoyToKey is a small application sold for a few dollars that takes gamepad input and converts it to mouse and keyboard output.

  • Using Your Smartphone As a Game Controller to Your PC
    Bachelor Thesis Computer Science June 2013 Using your Smartphone as a Game Controller to your PC Marcus Löwegren Rikard Johansson School of Computing BTH-Blekinge Institute of Technology Address: 371 79 Karlskrona, Telephone: +46 455 38 50 00 This thesis is submitted to the School of Computing at Blekinge Institute of Technology in par- tial fulfillment of the requirements for the degree of Bachelor in Computer Science. The thesis is equivalent to 10 weeks of full time studies. Abstract Many people in the world today own a smartphone. Smartphones of today usually have an ad- vanced array of inputs in forms of tilting, touching and speaking, and outputs in forms of visual representation on the screen, vibration of the smartphone and speakers for sound. They also usu- ally have different kinds of connectivity in forms of WLAN, Bluetooth and USB. Despite this we are still not seeing a lot of interaction between computers and smartphones, especially within games. We believe that the high presence of smartphones amongst people combined with the ad- vanced inputs and outputs of the smartphone and the connectivity possibilities makes the smart- phone a very viable option to be used as a game controller for the PC. We experimented with this developing the underlying architecture for the smartphone to communicate with the PC. Three different games were developed that users tested to see if the smartphone’s inputs are good enough to make it suitable for such purpose. We also attempted to find out if doing this made the gaming experience better, or in other words increased the enjoyment, of a PC game.

Abstract Background: Interest has been growing in the use of augmented reality (AR) based social communication interventions in autism spectrum disorders (ASD), yet little is known about their safety or negative effects, particularly in head-worn digital smartglasses. Research to understand the safety of smartglasses in people with ASD is crucial given that these individuals may have altered sensory sensitivity, impaired verbal and non-verbal communication, and may experience extreme distress in response to changes in routine or environment. Objective: The objective of this report was to assess the safety and negative effects of the Brain Power Autism System (BPAS), a novel AR smartglasses-based social communication aid for children and adults with ASD. BPAS uses emotion-based artificial intelligence and a smartglasses hardware platform that keeps users engaged in the social world by encouraging “heads-up” interaction, unlike tablet- or phone-based apps.

  • The Ergonomic Development of Video Game Controllers Raghav Bhardwaj* Department of Design and Technology, United World College of South East Asia, Singapore
    of Ergo al no rn m u ic o s J Bhardwaj, J Ergonomics 2017, 7:4 Journal of Ergonomics DOI: 10.4172/2165-7556.1000209 ISSN: 2165-7556 Research Article Article Open Access The Ergonomic Development of Video Game Controllers Raghav Bhardwaj* Department of Design and Technology, United World College of South East Asia, Singapore Abstract Video game controllers are often the primary input devices when playing video games on a myriad of consoles and systems. Many games are sometimes entirely shaped around a controller which makes the controllers paramount to a user’s gameplay experience. Due to the growth of the gaming industry and, by consequence, an increase in the variety of consumers, there has been an increased emphasis on the development of the ergonomics of modern video game controllers. These controllers now have to cater to a wider range of user anthropometrics and therefore manufacturers have to design their controllers in a manner that meets the anthropometric requirements for most of their potential users. This study aimed to analyse the evolution of video game controller ergonomics due to increased focus on user anthropometric data and to validate the hypothesis that these ergonomics have improved with successive generations of video game hardware. It has analysed and compared the key ergonomic features of the SEGA Genesis, Xbox, Xbox 360, and PS4 controllers to observe trends in their development, covering a range of 25 years of controller development. This study compared the dimensions of the key ergonomic features of the four controllers to ideal anthropometric values that have been standardised for use in other handheld devices such as TV remotes or machinery controls.
