Abstract
from arXiv · showhide
Oculus rift: Virtual reality (VR) is a burgeoning field that has the inherent potential of manipulating peoples mind with a superlative 3D experience. Oculus rift is one such application that assists in achieving the same. With the fleeting enhancements in VR it now seems very feasible to provide the user with experiences that were earlier thought to be merely a dream or a nightmare.
I. INTRODUCTION
Virtual reality creates simulated three-dimensional environments with visual, auditory, and tactile immersion. Oculus Rift is presented as a lightweight headset available in DK1 and more advanced DK2 developer-kit versions.
- I. INTRODUCTION: VR simulates a three-dimensional environment that gives users a sense of presence without concrete existence.The paper describes immersion through vision, sound, and tactile feedback.
- I. INTRODUCTION: The paper presents Oculus Rift as a technology intended to address motion sickness and dizziness associated with other VR headsets.This is stated as a claim about the new technology rather than as a reported comparative evaluation.
- I. INTRODUCTION: Oculus Rift is a lightweight headset that lets users enter games and look in any direction.The paper identifies two developer-kit versions: DK1 and the more advanced DK2.
- I. INTRODUCTION: DK1 includes positional tracking, while the supplied DK2 specification lists no positional tracking.The specification passages also list DK1 inputs as HDMI, USB, and an IR camera sync jack, while DK2 uses DVI and USB power.
- I. INTRODUCTION: DK1 uses a 640 x 800 display per eye with LED technology, while DK2 uses 960 x 1080 per eye with OLED technology.The listed resolutions are 512,000 total pixels per eye for DK1 and 1,036,800 for DK2.
III. INSIDE VIEW
The headset’s inside view is illustrated, and the Rift uses interchangeable lens pairs for different eyesight conditions. Lens changes require care because dust can create dead-pixel views, while some vision complications remain unsupported.
- III. INSIDE VIEW: The inside view of the Oculus Rift goggles is presented in a figure.The supplied caption identifies the image as the headset’s internal structure.
- III. INSIDE VIEW: The Rift includes lens pairs A, B, and C for users with different long- or near-sightedness conditions.Pair A is focused at infinity; pairs B and C address near-sightedness but are not suitable for everyone.
- III. INSIDE VIEW: Dust on either lens can produce a dead-pixel view, so lenses must be changed with precise care.The passage notes that dust particles may occur at different locations in both lenses.
A. Head tracking
Oculus Rift head tracking maps head movement to the virtual view, supporting natural observation and immersion. Its sensor system combines motion and compass components to reduce drift and latency.
- A. Head tracking: Head tracking lets users look around the virtual world as they would in the real world.The system controls the game view from head movement rather than a mouse or analogue stick.
- A. Head tracking: The tracker combines a gyroscope, accelerometer, and compass to correct drift across all three axes.The described board includes an MPU-6000 six-axis controller and an HMC5983 three-axis digital compass.
- A. Head tracking: The Oculus VR sensor supports sampling rates up to 1000 Hz, reducing the delay between head movement and game-engine sensor data to roughly 2 milliseconds.The paper also states that denser sampling reduces orientation error by providing more data for integration.
B. Position tracking
DK2 position tracking translates leaning and peeking movements into the virtual world. The control box supplies power, provides basic controls, and interfaces the headset with a computer.
- B. Position tracking: DK2 position tracking lets users lean toward objects or peek around walls by moving their head and upper body.The paper describes these physical actions as being translated into the virtual world.
- B. Position tracking: The paper states that added positional tracking helps reduce dizziness by addressing missing motion information.The explanation attributes this to preventing the brain from becoming confused by the missing degree of motion.
- B. Position tracking: The control box uses a standard 5 V DC USB power supply and connects the headset to computers through DVI, HDMI, mini-USB, and DC power ports.It also contains five buttons for contrast, brightness, and power.
V. INTERFACING
The Oculus SDK supports multiple operating systems and provides hardware and performance guidance for using the headset. The interface also supports gaming controllers and connects through USB with HDMI or DVI.
- The Oculus SDK supports MacOS, Windows Vista, 7, and 8, and Linux.
- The recommended system guidance includes 2 GB of RAM and a Direct3D10- or OpenGL 3-compatible video card.
- Lower-end and mobile graphics cards may run minimal demos but can be inadequate for full-scene 60 FPS rendering.
- The system supports Xbox 360 and Sony DualShock 3 controllers and connects the control box to the computer through USB using HDMI or DVI.
VI. SCREEN DOOR EFFECT AND GHOSTING
Ghosting is a visual artifact caused by slow pixel switching during head motion, producing faded trails and scene blur. A higher pixel switching rate is identified as the mitigation.
- Ghosting appears as faded trails behind moving objects in the Oculus Rift.
- Slow pixel switching causes ghosting because pixels change intensity more slowly than the user’s head moves.
- Faster head movements increase ghosting, which persists until the head stops and causes scene blurring.
- A higher pixel switching rate can avoid ghosting.
VII. RESULTS
The Oculus Rift is described as having a wide field of view and a high-resolution display. These features support an immersive experience in which users can feel inside a game.
- The Oculus Rift has a wide field of view.
- The headset has a high-resolution display.
- The Rift provides an immersive experience that allows users to step inside a favorite game.
VIII. CONCLUSION
The paper presents Oculus Rift as a VR device enabled by continuing advances in computer animation and simulation. It frames the headset as changing how users experience video games.
- VR devices such as Oculus Rift may support future real-time complex animation systems using simulation techniques.
- Oculus Rift is presented as a headset designed for video games.
- The paper states that the device will change how users think about gaming.
IX. FUTURE SCOPE
Virtual reality has potential applications across pilot training, scientific research, architecture, and entertainment. These uses include reducing fear of heights, examining chemical reactions, visualizing unbuilt structures, and creating virtual museum experiences.
- VR helps pilots overcome fear of heights during training.
- Scientists can use VR to examine chemical reactions and gather minute details.
- Architects can visualize unbuilt buildings and experience virtual tours of their structures.
- VR also provides entertainment through virtual experiences involving museums and other venues.
