Graphical user interface cursor positioning device having a negative inertia transfer function

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