Virtual 360 Tours For Fun And Recreation

By Mary Sullivan


When it comes to traveling the world, it can often be quite expensive. Now, with Virtual 360 tours, it is possible to do so without ever leaving home. Whether using this new technology for fun and recreation, or to view a number of institutions and museums, the technology can provide a great deal of entertainment.

While there are some free photographs and videos of this nature, most videos have a price. While this is the case, most visitors agree the experience is often worth the cost. Whereas, in order to see the content in person, it would cost far more than the price of a 360 virtual video.

AirPana was one of the first to develop this new technology. While this is the case, there are other companies currently involved in research and development of similar applications and programs. Basically, the photographs are created by using multiple cameras. Whereas, these videos also known as spherical or immersive videos are created using a multitude of equipment.

Most often this type of photography is photographed using a omnidirectional camera or multiple cameras. Once the photographs are stored, individuals can play back the photographs using a viewer which controls the photographs like a panorama. Whereas, 360 degree video is often formatted with an equirectangular projection using either a monoscopic or stereoscopic video camera.

The difference between stereoscopic and monoscopic relates to whether the operator is using a single or a multitude of cameras. Monoscoping refers to one camera while stereoscopic refers to multiple cameras. In most cases, the middle of videos using either of these techniques can often be blurry while the top and bottom are often clear. As with stereo equipment, the sound is also different between the two.

A number of specialized cameras and rigs have been developed for use with this new technology. Currently, there is a great deal of research and development with regards to the clarity of video. Whereas, there are other companies which are looking at how to best enter the field of competition in the area. Once this happens, the cost of videos and photographs will most likely go down over time.

These videos are generally viewed using personal computers, mobile devices or dedicated head mounted displays such as Virtual Reality headgear. When viewing on smart phones, there are internal sensors like the gyroscope which can be used to pan across images. While virtual reality headgear can be used to view these videos, it should be noted that it is often advised not to use a virtual reality headset for more than 30 to 55 minutes per session.

Websites providing these videos, while few and far between are often well stocked with videos and photographs. When planning on downloading photographs and video from these websites, individuals need to assure there is enough available space on the device in which the material will be stored, or better yet obtain an external mini-drive on which the media can be stored.
