Computer-implemented methods and systems for accessing data in a computer system by a user

A computer system including a graphical output device, an input device with an input device indicator that is visible on the display and reflects movement of the input device, and a computer program for displaying a window with contents on the graphical output device, the computer program carrying out a method for displaying the contents of a window, the method comprising the steps of:

• presenting on the graphical output device a first portion of a data object in a window, the data object containing a plurality of “N” data object items, at least one of the data object items being sought by the user, the data object containing more data object items than being presentable in said window at a given moment in time;
• providing on the graphical output device first and second control elements in relation to the presented data object, the first and second control elements being arranged to be activated by a user-operated input device in order to generate first and second request signals, respectively, upon such activation;
• and
• effecting, upon generating respective first or second request signals, a scroll step into a direction corresponding to the respectively generated first and second request signals having a predetermined step size “s” towards the data object item sought by the user, and presenting another portion of the data object in the window at least partially differing from the first portion of the data object, the step size “s” between subsequently presented portions of the data object decreasing in proportion with the number of generated first or second request signals to effect a series of one or more scroll steps towards the sought data object item among the data object items,
• wherein the step size “s” between subsequently presented portions of the data object is approximately determined by the equation:
• s
• =
• N
• #
• ⁢
• RXQ
• *
• a
• wherein:
• “s” defines the current step size;
• “N” defines the total number data object items;
• #RQX defines the number of previously generated respective first or second request signals to effect one or more scroll steps towards the sought data object item among the data object items;
• and
• a defines a fixed factor >1.
