To be truly immersive, virtual reality must stimulate our senses with realistic feedback. It can make everyday experiences, like playing games, watching movies & sports, video conferencing, and virtual travel, even more immersive.
Virtual reality places extreme requirements on several dimensions of visual quality, sound quality, and intuitive interactions. For example, we need tremendous pixel quality and quantity because the screen is so close to the eyes. We need realistic 3D positional audio so the sound is accurate to the real world. And we need interfaces so intuitive and responsive that you don’t realize you are even dealing with an interface. By focusing on all of these dimensions, a fully immersive experience can be achieved.
