The first thing we notice is that we can use the device not only as a Don't-touch-your-face-reminder. If we add a Bluetooth module, we can connect it to our smart phone and use it in addition for gesture recognition, so it becomes a smart cap. Device can be configured and trained via smart phone App.
Decided to divide the project into subprojects and design a number of dev boards before merging them into a single board. Start with the sensor dev board, will be equipped with three VL6180X sensors.
Soft on/off dev board with safe shutdown:
I'm 100% convinced my brain would quickly learn the sneaky side route to my face and I'd end up touching anyway. But I like the idea, and I clearly see the need for a passive reminder system like this.
Would be an interesting experiment.
Technically it's no problem to cover the whole face area using a couple of wide Field-of-View sensors, for example Chirp’s MEMS ultrasonic ToF sensor CH-101, datasheet can be found in FILES.

At first I thought it was something like an airblade fan, or those invisible car windshields to blow the germs away :P
