This document discusses various aspects of virtual reality (VR) technology, including hardware categories, typical head-mounted displays (HMDs), controllers, 3D cameras and audio, end-to-end platforms, and challenges that remain. It provides details on popular integrated and mobile-based HMDs such as Oculus Rift, HTC Vive, Samsung Gear VR and their specifications. Controller options like Leap Motion and Virtuix Omni are outlined along with haptic and 3D camera/audio technologies. Skills needed for VR development and available free software are also mentioned.

6. Oculus Rift
• It funded via Kickstarter and snapped by Facebook
• It has a resolution of 960x1080 per eye, a 90 Hz
refresh rate, and a wide field of view

two wireless Oculus Touch controllers to allow hand
tracking, and Xbox One control pad compatibility.
• Price : $TBC

7. Microsoft HoloLens
• It's half virtual and half augmented reality. It merges
real world elements with virtual 'holographic' images.
• There's no connection to a PC – a full Win 10 system is
built into the headset and runs off a battery
• It uses Kinect-style tech to recognize gestures and voice
commands, and the headset has a 120 degree FOV.
• There's no word on a release date
• Price : $TBC

8. Sony Project Morpheus
• It is designed to be fully functional with the
PlayStation 4 and PlayStation Vita game systems.
• It is currently a prototype and Sony says it will be
released in the first half of 2016.
• It included an OLED 1920x1080 display in 120fps. It
features a high FOV, 6DOF head-tracking, LED
controller.
• Price : $TBC

9. HTC Vive
• It’s developed in co-production between HTC and Valve
Corporation. The Vive plugs into PCs and work with
Valve's mammoth gaming ecosystem
• It packs 70 sensors(9 DOF), 360 degree head-tracking
and offers a 90Hz refresh rate.
• It is operated in a 15 feet by 15 feet (4.5 by 4.5 meters)
tracking space "Lighthouse”.
• Price : $TBC

10. Samsung Gear VR
• The Gear VR is an Oculus Rift powered device that uses a
Samsung Galaxy smartphone (Note 4 or Galaxy S6) as its
processor and display.
• The Galaxy handset simply slots in front of the lenses, into
a Micro USB dock, and uses its Super AMOLED display as
your screen.
• It's already added a host of games and a whole
marketplace of VR video content called Milk VR, which is
available in the US
• Price : $199.99

11. The comparison for typical VR HMD

12. Dream Specs for VR HMD
• 10K+ resolution per eye
• 2 ms persistence of pixel on screen
• 20 ms latency of total time between motion to
photon
• 160 degree field of view
• 120 Hz refresh rate of stereo render
• 1 mm accuracy on head tracking for rotation
and position

16. Leap Motion
• The Leap Motion controller is a small USB peripheral
device which is designed to be placed on a physical
desktop, facing upward.
• Using two monochromatic IR cameras and three infrared
LEDs, the device observes a roughly hemispherical area,
to a distance of about 1 meter (3.28084 feet).
• The LEDs generate pattern-less IR light and the cameras
capture almost 300 frames per second of reflected data
to analyze.

17. Virtuix Omni
• Virtuix launched a Kickstarter campaign in
June 2013 to raise money for manufacturing.
• The Omni is designed to accommodate a user
height ranging from (1.42 m – 1.95cm), and a
weight up to 285lbs (130kg)
• The Size are 47″x42″x27″, 160lbs.
• Price: $699
