1.0: data goes in one direction only: from the website to the user.

2.0: data goes in both directions: Internet users can interact with websites.

3.0: we don't talk about it... it's marketing. The "cloud" and social networks, which are not an innovation in themselves, but simply another way of presenting what already existed, daydreaming in the clouds.

4.0: first interactions with the real world and the senses: the addition of virtual reality, augmented reality and sometimes 3D printers. All this accelerated by the first innovation in terms of input devices after the keyboard and mouse: Eye tracking, the bidirectional interaction of sight; the understanding of the eyes by the computer.

5.0: Intersens. What BrainView is preparing: interaction with others, via the senses, even before writing, even before speech. Directly by thought.
