Hierarchy tree movement using multi-tree animation

A machine-readable storage medium that provides instructions which, when executed by a machine, cause said machine to perform operations including:

• displaying nodes in N number of levels of a first hierarchy tree on a display;
• receiving input of a selected node of the nodes to open a level below the N number of levels of the first hierarchy tree;
• fading out a number of nodes at a highest level of the N number of levels from the first hierarchy tree;
• fading in at least one node of the number of nodes at the highest level of the N number of levels into a second hierarchy tree;
• and
• fading in at least one node at a level below the selected node into the first hierarchy tree on the display;
• wherein at least one of a velocity and an acceleration of the fading out of the number of nodes, the fading in of the at least one node of the number of nodes at the highest level and the fading in of the at least one node at the level below the selected node decreases as a complexity of the first hierarchy tree increases.

An apparatus comprising:

• a display configured to display a first hierarchy tree having nodes in N number of levels;
• an input device configured to receive input of a selected node of the nodes to open a level below the N number of levels of the first hierarchy tree;
• and
• a tree module, in response to the selected node being received as input into the input device, configured to perform the following operations:
• fade out a number of nodes at a highest level of the N number of levels from the first hierarchy tree on the display;
• fade in at least one node of the number of nodes at the highest level of the N number of levels into a second hierarchy tree on the display;
• and
• fade in at least one node at a level below the selected node into the first hierarchy tree on the display;
• wherein at least one of a velocity and an acceleration of the fading out of the number of nodes, the fading in of the at least one node of the number of nodes at the highest level and the fading in of the at least one node at the level below the selected node decreases as a complexity of the first hierarchy tree increases.

An apparatus comprising:

• an input device configured to receive input of a selected node of nodes in N number of levels of a first hierarchy tree, wherein the input is configured to open a level below the N number of levels of the first hierarchy tree;
• and
• a display comprising,
• a first display zone configured to display the first hierarchy tree;
• a second display zone configured to display a second hierarchy tree,
• wherein, in response to receipt of the input of the selected node, nodes in a level of the N number of levels above the level that includes the selected node are faded out from the first hierarchy tree in the first display zone and a parent node of the selected node is faded into the second hierarchy tree in the second display zone;
• wherein at least one of a velocity and an acceleration of the fading out of the number of nodes and the fading in of the parent node decreases as a complexity of the first hierarchy tree increases.
