Commonly utilized in CAD applications, 3D modeling, animation, 3D visualization and product visualization, users can manipulate the controller's pressure-sensitive handle (historically referred to as either a cap, ball, mouse or knob) to fly through 3D environments or manipulate 3D models within an application. The appeal of these devices over a mouse and keyboard is the ability to pan, zoom and rotate 3D imagery simultaneously, without stopping to change directions using keyboard shortcuts or a software interface.

There are plenty of virtual reality games letting people soar like eagles and films surrounding you with Cirque du Soleil's acrobats. But the opportunities for people creating their own virtual reality home movies has been limited.
That's changing now as a number of consumer VR cameras hit the market, letting you do everything from putting together a 360-degree video of your kid's soccer game to capturing a holiday dinner with the family.

Unlike typical video cameras, these VR/360 cameras film in all directions (the 360 signifies a 360-degree film radius), giving viewers the option to see all around a scene as if they were swiveling their heads. While companies like Google and Lytro are working on professional grade cameras, several other companies are focusing on cameras for consumers.
Looking to try your hand as a virtual reality auteur or pep up your home movies? Here are a few affordable cameras that can help you do. Just keep in mind that, by and large, you'll need a VR headset— which cost from just $15 to several hundred dollarsto really get the full effect of virtual reality films.
