Virtual reality (VR) is a computer technology that uses headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds and other sensations that simulates a user's physical presence in a virtual or imaginary environment. A person using virtual reality equipment is able to "look around" the artificial world, and with high quality VR move about in it and interact with virtual features or items. VR headsets are head-mounted goggles with a screen in front of the eyes. Programs may include audio and sounds through speakers or headphones.
2. What is Virtual reality?
• Virtual Reality (VR) is a computer-simulated environment that can simulate
physical presence in places in the real world or imagined worlds.
• Virtual reality can recreate sensory experiences, which include virtual taste, sight,
smell, sound, and touch.
What can be VR
• Just about any simulated environment.
10. Accelerometer
• Accelerometer Provides the total force applied on the device.
• When device is stationary, this gives +1g (gravitational force)
reading in one axis and its components on other axes.
Gyroscopes
• Gyroscopes measure the rate of rotation around an axis. When the
device is not rotating, the sensor values will be zeroes.
• It gives us 3 value. – Pitch (around X – Roll (around y) – Azimuth
(around z)
11. Orientation sensor
• Orientation sensor measures degrees of rotation that a device
makes around all three physical axes (x, y, z)
Gravity Sensor
• Gravity sensor is not a saparate hardware but t’s a virtual sensor based
on the accelerometers, acceleration is removed from accelerometer
data.
