Mini-keyboard has sizes/spacings of keys combined so several keys can be tapped simultaneously; each character that can be entered is characterized/coded by keys simultaneously tapped by finger/object, can thus be recognized by processor

摘要

The device has a housing with keys (67,70,71), only one of which is tapped at a time using a finger (61) or object to enter a character. The sizes and spacings of the keys are combined so that several keys can be tapped simultaneously and each character that can be entered is characterized or coded by the keys simultaneously tapped by a finger or object and can thereby be recognized by a processor.
