Abstract
A keyboard integrated with a computer with a mechanism for determining a pressure sensitivity needed to register a desired keystroke is disclosed. A keystroke is registered for a given key if a force on the given key exceeds the determined pressure sensitivity. A user configuration profile can be utilized to specify a needed pressure sensitivity. Pressure sensitivity can also be determined dynamically. A threshold amount of pressure needed to register a keystroke can be compared to a measured amount of pressure applied during the keystroke and if the measured pressure meets the threshold pressure, the keystroke is registered. A control module, which can include an alphanumeric scale, can be utilized to set a threshold amount of pressure needed to register a keystroke. Some embodiments can also include a threshold amount of pressure set for each individual key.
