Solution Approach 1:

The pressure sensing capability is segmented into discrete granularity levels (e.g., 2-10 levels) that can be independently configured. This allows the system to provide enhanced input capability while managing complexity by dividing the continuous pressure range into manageable segments that can be controlled through software configuration rather than complex hardware circuitry.

AI summary

Systems and methods are disclosed for user configurable pressure sensitive keys and techniques for controlling these keys for keyboards. User configuration information, including information for user configurable granularity scales for pressure levels, can be communicated from a host system to the keyboard and stored for later use by a keyboard controller to control the operation of the pressure sensitive keys. In this way, greater control of the pressure sensitive keys can be provided. This configurability is of particular use for applications such as where the keyboard is being used for gaming by a user running a gaming application on an information handling system.
