It's interesting to explore the possibility space of communication, isn't it? We all use just a handful of communication modes, but so many more are possible. Here's an old idea of mine as an example: "Hands-only interface between two anonymous strangers who cannot hear or see each other, only touch and optionally see each other's hands. The elimination of usual communication channels like speech, facial expressions and body language makes this a novel way of interaction." If the participants don't know any predefined sign languages, what kind of information or emotion could they convey to each other? I look forward to extended reality and AI opening up a lot of the possibility space of wholly new communication modes.
