摘要：A user interface apparatus and method for a computing or processing systememploying a graphical user interface is presented. In order to provide a good user feel,and specifically to avoid a feeling of inertia or sluggishness in cursor motion as the user
starts or stops movement, the apparatus and method provide a negative inertia transferfunction. That is, the cursor movement signal produced by applying the input parameterto a transfer function in accordance with the invention is related to a sum of (i) the inputparameter, and (ii) a signal related to the rate of change of the input parameter. This ispreferably implemented as an additive high-pass transfer function. Preferred
embodiments can employ analog circuitry or a digitally programmed transfer functionalgorithm. The input parameter to which the transfer function is applied can be amagnitude signal, such as that from a polar coordinate system, or separate components,such as x- and y-components from a rectangular coordinate system, can be treatedseparately.
