Keyboard with a two-dimensional actuator for generating direction signals
First Claim
1. A keyboard for converting inputs entered by a user into corresponding signals comprising:
- an encoding circuit;
a plurality of text keys connected to the encoding circuit each for generating a corresponding text signal;
four direction keys connected to the encoding circuit each for generating a corresponding direction signal, each of the four direction keys being associated with a predefined direction and the four predefined directions of the four direction keys being different to each other; and
a two-dimensional actuator directly and electrically connected to the encoding circuit which can be actuated at least toward four directions which are the same as the four predefined directions of the four direction keys;
wherein when the actuator is actuated toward any of the four directions, the encoding circuit will generate the direction signal which is the same as the direction signal generated by the direction key of the corresponding predefined direction.

Abstract
The present invention relates to a keyboard with a two-dimensional actuator for generating direction signals which can be used to move a cursor shown on a screen to a target position. The keyboard comprises an encoding circuit, a plurality of text keys connected to the encoding circuit each for generating a corresponding text signal, four direction keys connected to the encoding circuit each for generating a corresponding direction signal, and a two-dimensional actuator connected to the encoding circuit which can be actuated at least toward four predefined directions which are the same as the four predefined directions of the four direction keys. When the actuator is actuated toward any of the four predefined directions, the encoding circuit will generate the direction signals which are the same as the direction signals generated by the corresponding direction key.

-
an encoding circuit; a plurality of text keys connected to the encoding circuit each for generating a corresponding text signal; four direction keys connected to the encoding circuit each for generating a corresponding direction signal, each of the four direction keys being associated with a different predefined direction and the four predefined directions of the four direction keys being perpendicular or parallel to each other; and a one-dimensional actuator directly and electrically connected to the encoding circuit which can be actuated toward two opposite directions which are the same as two opposite predefined directions of the four direction keys; wherein when the actuator is actuated toward any of the two opposite directions, the encoding circuit will generate a direction signal which is the same as the direction signal generated by the direction key of the corresponding predefined direction. - View Dependent Claims (7, 8, 9)
