Variable speed autoscroll system and method

摘要

A variable speed autoscroll system is disclosed. The variable speed scrolling system includes a control device, such as a scrolling wheel or other suitable control member. A user may select a scrolling speed by displacing the control member, and a non-linear increase in scrolling speed based on the degree of displacement of the control member is achieved. The control member may be disposed in a computer mouse, keyboard, or other peripheral device. In various embodiments, the user may toggle between various sensitivity levels to achieve a greater or lesser degree of increase in scrolling speed based on the amount of displacement of the control member. Optionally, the user may input the set of parameters to determine the dynamics of the system.

主权项

1. A variable speed scrolling system comprising:
a user controlled device having a control member adapted to enable a user to select a scrolling speed from a plurality of available scrolling speeds, wherein said device is adapted to be operatively connected to a computing system having a viewing screen, and wherein said scrolling speed determines the rate at which scrolling occurs within a document or between a series of images displayed to such a user on such a viewing screen when said device is operatively connected to such a computing system, wherein said control member is adapted to allow such a user to select said scrolling speed based on a degree of displacement of said control member, and wherein an increase in the degree of displacement results in a non-linear increase in a resulting scrolling speed, and wherein said scrolling speed is selected by such a user based on a degree to which the user positions said control member, and wherein said scrolling speed is determined based on predetermined parameters which are non-linearly proportional to the degree to which the user positions said control member wherein said scrolling speed increases in a non-linear manner based on the degree to which the user positions said control member.
