Abstract
A keyboard system including a plurality of hybrid key structures configured in an array of subarrays, each of the plurality of hybrid key structures configured within a subarray and including a depressible element, a first type of key switch configured to generate a first signal when the depressible element is activated, a second type of key switch configured to generate a second signal when the depressible element is activated, and processor(s) configured to: receive a first signal from an activated hybrid key structure when its corresponding depressible element is activated; determine a corresponding subarray that the activated hybrid key structure is configured within; scan the corresponding subarray for a generated second signal; detect the generated second signal from the corresponding subarray; identify the activated hybrid key structure based on the detected, generated second signal; and register a key press for the identified activated hybrid key structure.
