Abstract
A data input arrangement may include a first array of input keys defining a first shape extending across a first typing surface thereof; and a second array of input keys defining a second shape extending across a second typing surface thereof. The first and second arrays are contiguous with one another so that the first and second shapes create a non-linear surface extending across the data input arrangement. The non-linear surface enables users to tactilely locate individual keys of the first and second arrays.
