Abstract

A system stores visual content, and displays the visual content on a display unit in an undistorted, overview projection. The system receives input from a user to focus on a topic in the undistorted, overview projection, and transforms the undistorted, overview projection into a focused display showing the topic selected by the user and content related to the topic selected by the user in a continuous sequence of increasingly distorted projections. In the focused display, the content that is not related to the topic selected by the user does not move on the focused display, and the content that is related to the topic selected by the user moves towards the topic selected by the user on the focused display.

Claims

1. A non-transitory computer readable storage device comprising instructions that when executed by a processor execute a process comprising:

storing visual content in a computer storage device;

displaying the visual content on a display unit in an undistorted, overview projection;

receiving input from a user to focus on a topic in the undistorted, overview projection;

transforming the undistorted, overview projection into a focused display showing the topic selected by the user and content related to the topic selected by the user in a continuous sequence of increasingly distorted projections;

determining a relation among displayed topics;

fading out topics that are not related to the topic selected by the user during the transforming from the undistorted, overview projection to the focused display; and

moving content that is related to the topic selected by the user towards the selected topic on the focused display such that at a commencement of the transforming, movement of the content that is related to the topic selected by the user obeys a cambering hyperboloid projection, and in a course of the transforming, paths of the content that is related to the topic selected by the user are increasingly decoupled from the projected plane;

wherein content that is unrelated to the topic selected by the user becomes invisible at the end of the transformation irrespective of a location of the unrelated content on the undistorted, overview projection;

wherein content that is related to the topic selected by the user moves towards the topic selected by the user on the focused display; and

wherein the decoupling from the projected plane comprises a changing of a size of content that is related to the topic selected by the user and a distance of content that is related to the topic selected by the user from the selected topic as follows;

calculating a projected distance as follows;

2. The computer readable medium of claim 1, comprising calculating an adjusted logical distance of the projected distance as follows:
