摘要 |
A user interface apparatus and method for a computing or processing system employing 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 transfer function. That is, the cursor movement signal produced by applying the input parameter to a transfer function in accordance with the invention is related to a sum of (i) the input parameter, and (ii) a signal related to the rate of change of the input parameter. This is preferably implemented as an additive high-pass transfer function. Preferred embodiments can employ analog circuitry or a digitally programmed transfer function algorithm. The input parameter to which the transfer function is applied can be a magnitude 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 treated separately. <IMAGE> |
