Abstract

The invention relates to a keyboard system and a method of operating an input device. The keyboard system comprises a plurality of mixed key structures which are configured in an array form, wherein each hybrid key structure is configured within the sub-array and includes a depressible element, a first type key switch configured to generate a first signal when the depressible element is activated, a second type key switch configured to generate a second signal when the depressible element is activated, and a processor configured to receive the first signal and the second signal from the first type key switch. The processor is configured to: receive a first signal from the activated hybrid key structure when a corresponding depressible element of the activated hybrid key structure is activated; determining a corresponding sub-array configured with the activated hybrid key structure; scanning a corresponding sub-array for the generated second signal; detecting the generated second signal from the corresponding sub-array; identifying an activated hybrid key structure based on the detected generated second signal; and registering a key press with respect to the identified activated hybrid key structure.
