Patent ID: 7616193

Claim:
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 generating an operated-on data comparing the valid input data with a reference data, and operating and outputting a movement value using the reference data and the operated-on data, wherein the movement value calculating means includes: a valid input extractor for receiving the input data to determine whether the input data is valid or not and extracting and outputting the valid input data; a reference data storage for storing the reference data; a movement value operator for operating on the movement value using the operated-on data and the reference data; and an output unit for outputting the movement value, and wherein the valid input extractor adjusts the input data when contact indication bits indicating that the touch sensors are in contact are not continuous in the input data to make the contact indication bits continuous, and outputs the adjusted data as the valid input data.
