VR gives insane posibilitys.. one of them is digital timetravel..
This "setup" is not for the end consummer yet.. but thats not the point.. the point is.. it's posible.
For easy understanding I will use a living room as examble.
Cover a livingroom whit (lets say 10) 180 degree cams.. have a computer (using some alcorytmes) to put them together to a single VR space.. And store it all.
(could also add some heat/movement sensors on the cams.. (and take a "snapshot" every 5 minutes, when no recording to acount for light changes) for using less HD space)
In this examble.. lets say we "record" a year.
Now the "livingroom" is recorded in VR.. and put together to a single VR space.. (add some "simple" software for navigation.. voice and gesture controll makes sense)
Take a VR headset on.. And there you have it.. Digital timetravel to any point in time from that day and a year back.
You could say.. "april 15 (2019) 8.00 am" and you are at that point in time.. and see everything 100% precisely.
Offcourse only "digital" so no interagtion.. People and animals will walk right through you.. But you are there.. digital.
Or Use hands geture to scroll through time.. (like Lucy)
With the current boom in VR and 360 cams.. I think that end consumers can do this in under 5 years.. for less than 5000$ (but thats not the point :)
Eddit: Added "degree" to 180.. (becourse I could see that some thourgt i meant 180 cams)
