LATTICE KEYBOARDS WITH RELATED DEVICES

An electronic device may include a processor, a memory coupled to the processor, and a touch-enabled display coupled to the processor. The processor may be for generating a lattice of nodes of a circular packing being based upon a connected transformation of a square circular packing. The connected transformation may preserve adjacency between pairs of adjacent circles of the square circular packing after a transformation. The processor may also be for displaying a lattice keyboard on the touch-enabled display. The lattice keyboard may include keys, each of the key being associated with an input value and being selectable based on user touches provided to the touch enabled display. The keys may be arranged in a lattice pattern such that the center of each key is placed in the position of a respective node of the lattice.
