Abstract:
A system for controlling navigation of a data file, comprising:an input device having a user-actuated input mechanism for generating signals representative of input events; detection means for detecting a rate of user actuation of said mechanism; determination means for determining a data file navigation rate representing a navigation amount per input event as an increasing exponential function of the detected rate of user actuation; and output means for outputting control signals indicative of said navigation rate; wherein the function is the exponential function &Dgr;y=C+K1(1+K2&Dgr;t)&agr;, wherein &Dgr;y is the navigation rate, C is a constant, K1 and K2 are gain factors, &agr; is a non-linear parameter, and &Dgr;t is an indication of the rate of user actuation.
