    Roland- The market top was before the SOTU. I sold a bit of my Apple stock at it's peak of $180.00 using a trailing stop to catch the peak less a few pennies, then bought it back at $170. Bought a little more this morning at $158.00. I'm done now as I'm all in and out of cash. I've been buying heavy into this correction on Google, Boeing, Alibaba. I also sold all my Amazon to raise the cash for these buys. That was a really great run.

    BTW- Apple stock usually tanks after a great quarterly report. This time was no different. But this time it had company in that the big boys decided to sell off the whole market.

    Need a justification for buying the top iphoneX 256GB model?

    Very briefly, Ben shows what you can do with the iphone X as a 360VR video editor using a Rylo 360 camera and the iphoneX.

    The camera shoots in spherical but the app converts it to 2D. Isn't that kind of the antithesis of VR?

    All VR is actually shot in spherical and converted to equirectangular format which is a 2D image, unless the camera is designed for 3D ( two side by side lenses; a minimum of 4 cameras front and back). The only way you can get true VR is by viewing on an Head Mounted Display.

    The biggest disadvantage I see with present day 360VR technology is the resolution. Even with 4K cameras, the final equirectangular is limited to 4K UHD. When this is projected in true 4KVR, the resolution is reduced to 1/pi for the horizontal and 1/pi for the vertical. That makes the resolution less than HD quality. If the VR goggles are not also 4K screens per eye, then that further reduces the resolution to a quality more like the old VHS analog. This is a huge turn-off to most people. But I see other advantages to 360VR that intrigue me. Such as the ability to record the entire world around us at the same time and allow the viewer later on to see anything in that world we might have seen had we looked in that direction at the time of recording. With the VR HMD you can simply look around and the view you see is like you were there because the system uses a geo synchronous display that synchronizes your viewing direction with the video you see at the time. In addition, the system uses ambisonic stereo sound that allows you to hear sound that is synchronizes the direction with the view you see in the VR goggles. It's better than Dolby Atmos.

    The reason the resolution is limited is because the video is stretched in all directions so the pixels actually become larger than they were intended to be.

    Then as we have been told, the iphoneX uses a special graphics processor that allows the iphoneX to handle Augmented Reality into the Virtual Reality program. This opens up a whole new opportunity of programming, for example, you could make the image smart, such as add hotspots to the image that you can access additional information from the internet. You could add a menu to your video that constantly changes as the video plays. for example, say you were watching a travel documentary and wondered where that video was shot, you could select "Location" in the menu and a map would pop up with a location based on the geo locator meta data in the video. Of course a video editor would need to design all that but in the future, Apps could be added to basic VR editing that adds these tricks in a plug-in module to simplify the editing task.

    But before I get too carried away with what the process can do, I want to see that resolution limit fixed so the video in 360VR / AR is the same image quality as UHD.

    Currently, the technology has been achieved in the cameras by using 8 4K cameras for 4K to each eye for 3D. But the better VR HMD's only offer 2560 x 1440 for both eyes, which is 1280x720 per eye. Now divide that flat image by pi to approximate the image quality of the VR viewing. That gives us a screen that is 259x230 resolution equivalent. See what I mean? The technology doesn't even exist yet for 16K panels necessary for a true UHD VR Head Mounted Display

    There was a demo on the Amiga around 30 years ago that did this. The person in the camera frame was allowed to tap and kick "balloons" around them on the display.

    I recall that Amiga demo stuff. But Virtual Reality is a different experience. What is really creepy, IMO, is walking around with the 360VR camera in your hand and viewing the walk on your HMD in 3D and looking at yourself in the environment. If there was ever an out of body experience that is it when you see yourself in 3D inside a virtual world. It looks so real. Seeing yourself in 3D on a flat screen is nowhere near the same.

    I imagine that excitement would last a few minutes and then I'd be on to the next ride at the amusement park.

    I find that the processing delays inherent in modern video gear to be too distracting to give an accurate sensation.

    I had my first modern VR experience at the Jaguar booth during the 2018 Chicago Auto Show. Using the HTC Vibe headset, Jaguar virtually put you inside the upcoming I-Pace electric crossover. I was impressed how well the Vibe headset was ticking my movements. At one point, I got up (going through the roof of the VR I-Pace) and was able to see the car from the outside. I sat back down and stuck my head out the window, looked around, got back in and checked out the back seat. Like Don mentioned, apparent resolution is not HD but I was more impressed with not getting motion sick from the display. I could not detect any lag in my head movements and the view my brain expected to see.

    I did not see the magic behind the scenes (in other words, the graphics workstation driving the HTC) but I expect it was rather beefy.

    Therein lies the problem. Video processing power requirements in 3D go up perhaps by the cube if not more.

    Then again, the human brain is pretty adept at making things look more realistic than they are.
