Keyboard Stealth Typing

Problem: In some cases a user might want to conceal they are using their phone.

For Example:

1. They need to conceal their location

2. Don't want to disturb others

3. In a private location, such as a bathroom

Smartphones and other portable devices can be quite loud when clicking away on the keyboard. How can we support the above use cases better?

Solution:

A “stealth mode” would allow the user to use their keyboard without having to press or "click" the keys.

Instead this mode would allow them to just touch the keys.

When a press is detected on a capacitive keyboard, it is mapped to a key that lies within the range of the (x,y) coordinate given. This solution is best implemented into the keyboard or at a lower level key injection.

It could be integrated with “touch to type” systems as a privacy or night mode of operation where it's only active under those conditions.

Another use case for this feature is for when a user just doesn't like clicking keys - maybe the user still like to feel the key when they touch it and like how the keyboard is always available and not obscuring the screen.

How it Might Work

A capacitive layer may not fully cover the keys due to the metal component which allows the key presses to be detected – so we may not have a high resolution of detection, but it should be decent given the limitations.

The software could listen for presses on the keyboard. When a press is detected it can be mapped to a key that lies within t...
