Wearable computing ideas

So the idea came up of a simple commuter setup that would allow someone to type while standing up in a crowded train. The system would be compact & light enough to run down 1 mile of city streets. How could it be done as simply & cheaply as possible?

It amounts to 2 inventions that went absolutely nowhere: the virtual reality goggle & the wearable keyboard. Google glass would have been the ideal form factor, but it only did 640x360. No virtual reality goggle has ever been mass produced. Google cardboard might work, but would need a camera projecting outside video in a window. Maybe a new kind of goggle with no sides can be invented. The cheap phone is only 480x800.

The most effective keyboard leans toward a rubber thing. The rubber thing contains a full keyboard & touchpad. A different full keyboard & touchpad is worn on each side of the abdomen. If not a full keyboard, each side overlaps the other by a few keys. Maybe it could be a single rubber keyboard on the abdomen.

This amounts to a lot of money. Maybe there's an incremental step from the bog standard phone.

The average commuter stares at a phone screen, desperately trying to be entertained by what meager, meaningless news bites it can download between tunnels. Don't know what they did 30 years ago.

The mane limitation with this scheme is 1 handed or 1 fingered typing being extremely slow. What you need is a 3rd arm to hold the phone so both hands can type. If an arm can be designed, it conceivably simplifies the problem quite a bit. A simple arm to hold the phone combined with the abdomen keyboard might do the job.

Searches for wearable computing show a wasteland of vaporware stretching 5 years into the past. There's much more vaporware than the old days, showing how much longer vaporware can survive without making money than it used to.
