New Cameras and Apps Drive Augmented and Virtual Reality

New Cameras and Apps Drive Augmented and Virtual Reality

At the 2016 Consumer Electronics Show and since then, there have been hordes of people wearing funny goggles, waving their hands or pointing to something only they can see. Welcome to the world of augmented reality (AG) and virtual reality (VR). The advent of eye-based, high-resolution mobile displays is upon us and it is going to change the way we look at the world, real and imaginary.

Facebook’s Oculus Rift is an example of virtual-reality goggles that provide an immersive environment where all visual feedback is through the goggles. Head tracking is critical to the presentation for gaming where VR is popular, especially when combined with other tools like the Virtuix Omni or Kat Walk treadmill.

Microsoft’s HoloLens is an example of AR goggles (Fig. 1). AR adds to what a person normally sees. It can be used for gaming, but there are many other AR applications. It provides a heads-up display that can show general information or location/viewing information based on a person’s current location. Some applications synchronize the view with objects in the view allowing overlays such as training or support information.

1. Microsoft’s HoloLens is an augmented reality system designed to overlay imagery that blends with the user’s real view of the world.

Many AR and VR applications are being made more practical with 360-deg. cameras. The Vuze VR Camera (Fig. 2) can record 360-deg. HD video streams simultaneously from eight cameras spaced around the unit. It can record to an SD flash card for an hour. Each camera has an ultra-wide and vertical angle lenses to capture 120-deg. horizontal and 180-deg. vertical images. The videos are knitted together to create a 4K resolution, 360-deg. video. The cameras have overlapping coverage to provide stereoscopic videos.

2. Vuze VR generates a 360-deg. stereoscopic view using eight cameras.

The $449 Kodak PIXPRO SP360 Action Camera records a 360-deg. hemisphere with a 1080p resolution (Fig. 3). A 4K version is also available. The SP360 uses a single, 16 Mpixel camera and an interesting curved, spherical lens. It records at 10 frames/s. The battery-operated camera can record at 1080p for 160 minutes. The camera records to a microSD card or via the wireless 802.11n support.

3. Kodak PIXPRO SP360 Action Camera is a 4K, 360-deg. hemispherical camera. Two can be paired to record a complete sphere.

What is very interesting about the SP360 is that two can be paired and synchronized to provide a recording sphere. They do not have to be adjacent to each other to do this. For example, one can be placed on top of a quadcopter and the other on the bottom so the recorded video does not show the quadcopter in the video. The magic is done by the post-production knitting software.

Not all AR/VR applications need recorded video, but many do. This may eventually be the norm in the same way that smartphones have replaced cameras and camcorders for most users. The PIXPRO SP360 and Vuze VR are just two of a growing number of similar cameras. Likewise, the Oculus Rift and HoloLens are just two of a similar growing family of VR and AR goggles. The best is yet to come.
