Keyboardless keyboard

Sometimes we need to interface with a computer without having to rely on a physical keyboard. For instance, most combat situations would preclude the use of a keyboard, as would working on power lines, or when your hands are covered in oil, etc...so, this idea, whether it already exists or not, is for those and similar situations, both current and future.

This seems problematic

Hardware
Make a glove with pressure sensors sewn into the finger tips that are "spatially aware" of one another. When activated, the sensors send wireless signals to a computer, smartphone, or HUD device via bluetooth, where each signal tells the device which finger was tapped and where that finger was, positionally, relative to all other fingers (or perhaps just relative to the thumbs, since they tend to stay in one place) when it was tapped.

Software
The software that utilizes the signals should be coded to take advantage of computer learning and pattern recognition (as well as traditional word prediction and auto-correction) so that each word in the dictionary can be turned into an approximate pattern of pressure and position signals from relevant fingers. The pattern recognition software should be coded so that it can adapt to the nuances and quirks of individuals. In this way, the longer a person uses the software, the more useful it becomes for that individual. This computer learning and bio-feedback data should be stored in separate files from the base software, and made transferable, so that if the glove is damaged, the individual can transfer the files to a new set of gloves without having to start from scratch. The glove and the software should not activate until needed, perhaps by the push of a button or by bringing the thumbs to within one inch of each other, otherwise inputs would be made randomly while wearing the gloves.

Function
This system allows the user to treat any flat surface as a keyboard.

Perks
It could also operate as a mouse by holding the left hand motionless as a reference point for the right hand. The fore and middle fingers could then be tapped as left and right mouse buttons.
This system could be built into preexisting military gloves, work gloves, or consumer gloves.
