Abstract:
Systems and methods according to the present invention address these needs and others by providing a handheld device, e.g., a 3D pointing device, which uses hand tremor as an input. One or more sensors within the handheld device detect a user's hand tremor and identify the user based on the detected tremor.
Abstract:
A bias value associated with a sensor, e.g., a time-varying, non-zero value which is output from a sensor when it is motionless, is estimated using at least two, different bias estimating techniques. A resultant combined or selected bias estimate may then be used to compensate the biased output of the sensor in, e.g., a 3D pointing device.
