1. A method comprising the steps of: a. examining a human hand with respect to sensor surface and periodically producing first indications regarding the nature and position of sensed contacts, the contacts comprising identified hand parts; b. evaluating the first indications to determine if two or more hand parts activate the sensor surface substantially simultaneously, and producing second indications identifying any such hand parts; c. evaluating the first indications to determine if the character of sensed contacts is consistent with typing and producing third indication identifying such typing in response thereto; d. evaluating second indications and third indications and making corrections regarding the third indication based upon the second indication, but only if the second indication identifies fingers.
