Apparatuses and systems for generating characters for electronic devices using condensed keyboards are disclosed. One embodiment comprises a keyboard that monitors two sets of keys, one for each hand, for manipulation and desired character generation. The keyboard generally has four or more keys for each hand, and the keyboard may be located on the back and/or sides of a portable electronic device. One or several of the keys may generate multiple characters, depending on how the user manipulates the key while depressing it. A further embodiment may display cues of help information on a display screen of the system, assisting users in typing with the keys since the users may be unable to easily observe their fingers. That is to say, some embodiments may provide support for people with no touch-typing skills and accommodate key configurations on the back of devices with an embodiment keyboard.
