Have you ever suddenly locked eyes with another person? Even if it only lasts a moment, it is a powerful sensation.
We can tell when somebody is looking right into our eyes even if they are all the way across a room. It is quite remarkable that we can do this, considering the tolerances involved.
At some point wearable technology will advance far enough that our devices will know exactly where we are looking. When that happens, the computer network will know when two people are looking directly into each others’ eyes.
Which means that eye contact will become a way to trigger various other modes of communication. For example, we might be able to speak softly under our breath, and be heard only by the person we are locking eyes with.
The possibilities for more powerful forms of communication are endless. And at some point it will all just be taken for granted.
