I commute a lot on public transport within Munich, Germany.
Of course i see countless beautiful women that i feel attracted to.
Here’s what i thought could be interesting – a small camera that sees what i see (Google Glasses?) and tracks ALL faces that i encounter. When i look at someone for longer than a second a snapshot of my bodily measures is being taken through arousal-measuring sensors (heartbeat, muscle activity…) and stored in association to that person. Through a throat microphone i can discreetly attach voice-notes without having to speak out loud. I get displayed anything i might already have stored about this person (in addition to parameters that can be measured instantly, like body-height) – if i have seen her/him before and what was related to that encounter. Over time this builds a substantial database of people that commute around the time that i do and that i find interesting.
If everyone would have such a device and all devices are networked – automatic match-making based on mutual arousal could take place. It would be displayed for both parties as a suggestion to say hi.
Anyway. Put this into the category of geeky tech-visions as compensation for being to shy to say hi from the beginning. I admit it.
