The Definition Of Virtual Reality (VR)

Virtual Reality(VR)

What is VR? : The definition of VR is simulation of the real environment to make the imagination environment that feel like the real environment from human senses, the important senses to create the virtual reality is 1.Seeing 2.Touching 3.Smelling 4. Hearing by using some accessory such as Head set, this head set will make you feel like you are in the virtual reality world with less feeling from the real world. Now we will often see virtual reality in game centre and we will often see virtual reality use with your smart phone.

History of VR :

In 1995 : Morton Heiling invent the sensoroma the simulation machine to simulate the 3D picture that increase some sense for reality

In 1961 : Philco Corp. develop head sight

If we put the main process of stereoscope combine with high resolution and high quality make stereoscope be more real. First step to make the virtual reality headset or virtual reality glasses first the slide make the video in 3D and make it in 360 degree and play on display screen after that we put the speaker of headphone on Virtual reality head set for the sound on real time video. To create the real movement we will use tracking sensor, This is the important thing to make virtual reality glasses feel so real.

Sensor of Virtual Reality Glassess or Virtual Reality Headset

The important thing to make real motion or real movement on virtual reality glasses is tracking sensors, In virtual reality glasses use 3 important sensors.

1. Accelerometers

The process of accelerometers will measure the acceleration of 3 axis (XYZ).Accelerometers will measure the acceleration of each axis one by one. Accelerometers has one problem if device move parallel to the earth Accelerometers can’t measure this change of value. Because accelerometers can detect only when the device come to the tilted position. From that’s problem make Gyro sensor is better than Accelerometers

Accelerometers in Virtual Reality :

In the virtual reality controller, accelerometers sensor will detect the movement of user’s hand direction.
