Abstract

The computer keyboard is compact for easy holding and operating by hands. In a front portion, a wireless signal transmitter is housed. Two lateral sides are curved downward to form two hand-held portions for convenient hand holding. On the top surface of the computer keyboard where the two thumbs could easily reach, an ordinary computer key pad is laid out. In the key pad, a special key is provided, which could switch the definitions of some keys, and allow the configuration of key combinations to perform a specific control function. As such, the computer keyboard is able to use a minimum number of keys in the key pad. On the bottom surface where the index or middle fingers could easily touch, a touch pad is provided for controlling the computer cursor.
