Looking into the not-so-distant future, the use of smart materials could make it possible to create new forms of physical play that could be controlled remotely either by a person or by some form of artificial intelligence. Hopefully, your digital assistant doesn’t forget your safe word.
Soft robotics, programmable matter, or some combination of the two could take the form of a kind of garment that a submissive could wear. This way they could be rewarded with sexual pleasure, a form of bondage, or punished by short, intense pressure simulating getting whipped or another type of instrument causing short bursts of pain.
Safety, again, would be paramount this system. Biometric sensors would tell the person or program in charge exactly how much pressure or pleasure the submissive could safely take—and if something were to go wrong, the hardware/software solution would immediately call for medical assistance.
