  • Method and system for managing data flow within a collaboration system using proximity determination modules
    Patent number: 6035337
    Abstract: Applications are enabled to provide information about which hosts should receive data generated by each host in a collaborative system. The data flow information is enabled, and the way that data flows is calculated to be dynamically changed during the application's execution. This data flow customization is enabled within a generic communication infrastructure. The application's specification of the data distribution is decoupled from the low-level mechanisms used to actually disseminate data across the network.

  • Method and system for managing multi-user data flows in environments having minimal bandwidth and computational resources
    Patent number: 6012092
    Abstract: The overall management task required to determine data dissemination in multi-user applications is reduced herein. The management task required at any one host in the multi-user application is also limited. In addition, the number of simultaneous connections that any one participating host must support in a large multi-user application is reduced. Each user is assigned to a single management partition.

  • Method and system for authentication over a distributed service to limit password compromise
    Patent number: 6006334
    Abstract: No more than one user at any one time is allowed to access a distributed service for each User ID and password. A user is allowed initial access to the distributed service with a password. The use of the distributed service is then restricted to the user upon entering the password plus a random factor created by the user. A user record is created as a unique recorded registration.

  • Method and system for a remote notification service for a multi-user server architecture
    Patent number: 5920692
    Abstract: An optimized design for a multi-user server architecture for disseminating a variety of real-time application data, such as audio, video, text and motion, while supporting general purpose tools. A general server system without an imposed GUI enables the end purchaser to customize the user interface as well as execute tools to monitor and control the operation of the system.

  • Automatic and configurable viewpoint switching in a 3D scene
    Patent number: 5907328
    Abstract: A method and apparatus for automatically changing a user's avatar's displayed view perspective in a virtual world upon execution of a gesture by the avatar, and in which the view perspective is changed for each gesture. The configuration of the view perspective switching specifies an action, a speed, a position and a return time. An avatar implementing the present invention allows the user to avoid manual view perspective switching which interferes with the immersive environment of a virtual world.
