Interactive visualization or interactive visualisation is a branch of graphic visualization in computer science that involves studying how humans interact with computers to create graphic illustrations of information and how this process can be made more efficient.

Systems and methods for collaborative interactive visualization of 3D data sets over a network ("DextroNet")

Exemplary systems and methods are provided by which multiple persons in remote physical locations can collaboratively interactively visualize a 3D data set substantially simultaneously. In exemplary embodiments of the present invention, there can be, for example, a main workstation and one or more remote workstations connected via a data network. A given main workstation can be, for example, an augmented reality surgical navigation system, or a 3D visualization system, and each workstation can have the same 3D data set loaded. Additionally, a given workstation can combine real-time imagining with previously obtained 3D data, such as, for example, real-time or pre-recorded video, or information such as that provided by a managed 3D ultrasound visualization system. A user at a remote workstation can perform a given diagnostic or therapeutic procedure, such as, for example, surgical navigation or fluoroscopy, or can receive instruction from another user at a main workstation where the commonly stored 3D data set is used to illustrate the lecture. A user at a main workstation can, for example, see the virtual tools used by each remote user as well as their motions, and each remote user can, for example, see the virtual tool of the main user and its respective effects on the data set at the remote workstation. For example, the remote workstation can display the main workstation's virtual tool operating on the 3D data set at the remote workstation via a virtual control panel of said local machine in the same manner as if said virtual tool was a probe associated with that remote workstation. In exemplary embodiments of the present invention each user's virtual tools can be represented by their IP address, a distinct color, and / or other differentiating designation. In exemplary embodiments of the present invention the data network can be either low or high bandwidth. In low bandwidth embodiments a 3D data set can be pre-loaded onto each user's workstation and only the motions of a main user's virtual tool and manipulations of the data set sent over the network. In high bandwidth embodiments, for example, real-time images, such as, for example, video, ultrasound or fluoroscopic images, can be also sent over the network as well.

Methods for interactive visualization of spreading activation using time tubes and disk trees

Methods for displaying results of a spreading activation algorithm and for defining an activation input vector for the spreading activation algorithm are disclosed. A planar disk tree is used to represent the generalized graph structure being modeled in a spreading activation algorithm. Activation bars on some or all nodes of the planar disk tree in the dimension perpendicular to the disk tree encode the final activation level resulting at the end of N iterations of the spreading activation algorithm. The number of nodes for which activation bars are displayed may be a predetermined number, a predetermine fraction of all nodes, or a determined by a predetermined activation level threshold. The final activation levels resulting from activation spread through more than one flow network corresponding to the same generalized graph are displayed as color encoded segments on the activation bars. Content, usage, topology, or recommendation flow networks may be used for spreading activation. The difference between spreading activation through different flow networks corresponding to the same generalized graph may be displayed by subtracting the resulting activation patterns from each network and displaying the difference. The spreading activation input vector is determined by continually measuring the dwell time that the user's cursor spends on a displayed node. Activation vectors at various intermediate steps of the N-step spreading activation algorithm are color encoded onto nodes of disk trees within time tubes. The activation input vector and the activation vectors resulting from all N steps are displayed in a time tube having N+1 planar disk trees. Alternatively, a periodic subset of all N activation vectors are displayed, or a subset showing planar disk trees representing large changes in activation levels or phase shifts are displayed while planar disk trees representing smaller changes in activation levels are not displayed.

Heterogeneous network interactive visualization method

InactiveCN104090957ARealize detailed association analysisControl Visual ComplexityOther databases browsing/visualisationSpecial data processing applicationsGranularityHeterogeneous network
The invention discloses a heterogeneous network interactive visualization method. The method comprises the steps that (1) nodes in a heterogeneous network are clustered according to node attribute values, and a corresponding clustering network visualization map is generated; (2) as for each node in selected clustering results, a neighbor node set of the node is calculated; then according to the node attribute values of the adjacent node sets, the nodes in the clustering results are clustered; a clustering visualization map is generated as a next-level visualization map; (3) the clustering results obtained in the step (2) are selected, the nodes in the clustering results are clustered according to the adjacent node sets of the nodes, and the nodes with the same adjacent node set fall into the same cluster; then the clustering results are used for generating a clustering visualization map which is used as a next-level visualization map of the clustering network visualization map generated in the step (2). According to the heterogeneous network interactive visualization method, topological information and attribute information are combined, and a user can check the lower level with the finer granularity.
