Human input apparatus with touch sensors and method for calculating movement value thereof

A human input apparatus comprising:

• a plurality of touch sensors for varying and outputting output signals by direct contact;
• a sensing unit for receiving the output signals in parallel from the plurality of touch sensors and outputting input data in response to the output signals;
• and
• a movement value calculating means for extracting valid input data from the input data and calculating and outputting a movement value using input data upper and lower points that are most and least significant bits of the valid input data indicating that the touch sensors are in contact and reference data upper and lower points that are most and least significant bits of the reference data indicating that the touch sensors are in contact.

A method for calculating a movement value of a human input apparatus including a plurality of touch sensors for varying and outputting output signals by direct contact, and a sensing unit for receiving the output signals in parallel from the plurality of touch sensors and outputting input data in response to the output signals, the method comprising:

• a valid input data extracting step of receiving the input data to determine whether or not the input data is valid and outputting valid input data;
• a movement value operating step of operating on the movement value using operated-on data comparing the valid input data with reference data and the reference data;
• a reference data changing step of changing the reference data into the valid input data;
• and
• a movement value outputting step of outputting the movement value.
