I hung out with my past self in virtual reality
The new VR capture collects data on everything happening in the three-dimensional environment, so that during a replay a viewer can move freely around the space. As a nice gimmick, viewers inside a replay can even interact with certain items, for example grabbing a glow stick.
I checked out a replay of a Reggie Watts show and definitely felt like the energy and movement of his character came across.
For the average user, you now have the trippy opportunity to do something, then watch and, in a very limited way, interact with your past self. In clear violation of the Prime Directive, you can reach out and grab objects from out of your past self’s hand.
I can imagine that as our ability to capture what your real body is doing, this would open up incredible opportunities for athletes, dancers, and performers of all stripes to evaluate and perfect their own body language and position. For artists, there is also an opportunity to create interactive works that employ multiple versions of yourself. Instead of just layering samples of his own voice and instruments, Reggie Watts can start looping himself.
