If Tesla optimus robots were breaking into my house at night, logging into my computer, and using my web browser, this would be one solution.

You didn't mention anything about how the web server knows if the other end of the connection is this user-hostile browser or a python/javascript bot with a spoofed user agent.

All interesting ideas but to get traction make it part of a low latency haptic suit that people can use to sex each other up or show off their PVPness, make some prototypes for executives and investors to play with and I could see it getting attention. Maybe get a demo integrated with VRChat. On the more taboo end and to not discriminate make all sizes of suits for all body types and ages. Provide an SDK so that all gaming companies can incorporate your suit. That should give "Collision Detection" a whole new meaning and experience.

One day the glove will have some connection problem and you won't be able to troubleshoot it because you can't use the internet.

This would always need some backup solution and now you're back on square one.

Edit: also you'd need accessibility, so a glove is out. And how do you handle game consoles? Voice assistants like Siri or Alexa?

1. I wouldn't want to wear a glove while typing. 2. Maybe for something like nuclear missile control you would want extremely high security like this, but for something like low stakes like a google search it seems overkill.

All that might be good until government will take over that idea to kill anonymity. In case that glove can also get a human fingerprints.

Maybe an attacker could record a couple hours of glove usage, and then replay this with slight variations.

I do not want to wear any smart tech for any reason.

Sell it to Mark Zuckerberg.
