Yes, it is an invasion of privacy. The signals being sent out are not audible in themselves, but appear audibly perceived in the cranium.
“The signals being sent out are not audible in themselves, but appear audibly perceived in the cranium.”
So this must be a bit different than those “whisper cones” that they have set up in the local children’s museum (which is also pretty cool!!). If it is actualy “in the cranium” could this have a good application for deaf people?
That’s not an invasion of privacy, for all the reasons I already listed.
