I think some of these things are solvable right now in software. I would say that most interactive setups start with handsfree (am using the belt setup the ‘ballsy’ 3d print) and VR. For tech if you add in AR passthrough and get the scale right, you are now in your room, and then if you can struggle through the virt-a-mate set up with passthrough at roomscale and get it controlling the toy in a scene that is well developed and a 3d model then you are on another level as well.
So for interactivity, once you are in some state where you can convince yourself that what you are looking at is ‘real’ it comes down to the software and the content. For videos they are really on rails and it will rely on content. Most content that we digest is a man who has injected something right into his dick to numb and make it hard at the same time while an incredibly attractive girl hammers on it with practiced proficiency. Most of us are going to explode immediately in that situation IRL, which is why it’s very hard to essentially become the person in the video. However if the pacing of the video is correct, the man is aroused, and the woman is keeping him there in sequence, you can almost mentally link up with the scene such that you are pretty much having the same arousal cycles as the male actor and as the woman works him up and down again you are getting the same treat.
But really the simplest solution is to have a remote or control in your hand and can push a ‘cumming’ button so the video can skip to a cumming sequence that has appropriate motion.
For more interactivity where if you had a 3d model that could adjust on the fly like vam (potentially) could, you would just need an arousal slider to modify as you are feeling things, clicking up/down from soft to hard to edging to cumming. It would be very difficult to write but not impossible. You just nee to then have the character adjust actions in real time, like if the user was at an 8 and they go down to a 4 it would know to adjust the sequence to something that the user likes better or need to restart up, or just if you are clicking every edge out it could use that in real time to keep you there if that was the goal.
We have the tech right now to have a lot more interactivity, just we are missing the software driving it and software linking everything all together. The realtouch, maybe over a decade old by now, proved this all out that we had the means. The final level of interactivity is the joystick and webcam driving things over cam with two people involved with one another which is probably as good as you get.
Really the porn thing as a could hanging over everything slows it down, but things have progressed really nicely and I think we’ll continue to drive towards it. I do think that we could simulate much more interactivity right now, just the knowledge and willpower to do so isn’t quite there yet, but I do believe it is building.
The low hanging fruit that could probably be done today is another common format next to the funscript that has arousal timestamps and a video player that has inputs for adjusting arousal, at a minimal a ‘cumming’ button that hops to the cum sequence in the video, but could also skip to other video files or timestamps for ‘soft to hard’ or ‘edging to mid’ or ‘edging sequences’ etc.
