A system for providing a tactile virtual world or environment wherein, in particular, a virtual reality environment provides an interactive 3-D interface for synthesizing the feeling of experiencing a 3-D environment. The invention also provides a method for implementing actual physical applications that can simulate real 3-D environments; for example, such as a physical training exercise or artificial 3-D environments, or simulating the interacting with molecules or complex data sets.

The present invention discloses a creation of a virtual hand, body part, or tool in a virtual environment, controlled by a new 3-D haptic interface for virtual environments. There is also the provision of a method and arrangement applicable to computer systems for creating a virtual environment, which facilitates a user to touch, feel, edit, and interact with data about the objects, surfaces, and textures in the environment. There is also a provision for multiple virtual hands operating in the same virtual world, so that users can work collaboratively in the virtual world; they can touch, feel and edit the data in the virtual world, including data about the other users' virtual hands.

The present invention discloses a tactile input/output device for representing and manipulating computer-generated surfaces. Also disclosed are a novel system and method for implementing the forgoing aspects. In essence, there is provided an intuitive concept of manipulating and editing a computer-generated surface, by employing a combination of traditional input and output devices (keyboard, mouse, display, etc.) and a novel device that enables users to touch, edit and modify a physical representation of the surface. The tactile device includes an array of displaceable pins, which are driven by a control system having a plurality of micro-actuators operating in combination with a rack-and-pinion assembly.

A system comprising a receiver and a transmitter for sending and receiving audio-video datastreams through fixed IP addresses, which IP addresses are established upon initialization of the transmitter and receiver systems. The transmitter includes an audio-visual capture and encoding subsystems, and the receiver includes an audio-visual decoding and display subsystems.

A plurality of applications are integrated in a system by merging three-dimensional (3-D) display data contributions from the respective applications into a single display scene using a visual integration hub. The respective contributions of display data may be separately manipulated to establish registration or relative positioning and then locked together such that the composite image may be graphically manipulated as a single object. Two-dimensional (2-D) data such as text or spreadsheets are imbedded in the image and manipulated in the same manner as 3-D objects. The hub allows transfer of graphic data between applications and conversion of the graphic data to the format of each respective application.

A system and method for seamlessly combining client-only rendering techniques with server-only rendering techniques. The approach uses a composite stream containing three distinct streams. Two of the streams are synchronized and transmit camera definition, video of server-rendered objects, and a time dependent depth map for the server-rendered object. The third stream is available to send geometry from the server to the client, for local rendering if appropriate. The invention can satisfy a number of viewing applications. For example, initially the most relevant geometry can stream to the client for high quality local rendering while the server delivers renderings of less relevant geometry at lower resolutions. After the most relevant geometry has been delivered to the client, the less important geometry can be optionally streamed to the client to increase the fidelity of the entire scene. In the limit, all of the geometry is transferred to the client and the situation corresponds to client-only rendering system where local graphics hardware is used to improve fidelity and reduce bandwidth. Alternatively, if a client does not have local three-dimensional graphics capability then the server can transmit only the video of the server-rendered object and drop the other two streams. In either case, the approach also permits for a progressive improvement in the server-rendered image whenever the scene becomes static. Bandwidth that was previously used to represent changing images is allocated to improving the fidelity of the server-rendered image whenever the scene becomes static.

A computer graphics system includes a graphics processing engine for processing and displaying graphics data representing three-dimensional objects in a first portion of a display. A text processing engine displays text in a second portion of the display. Embedded in the text is a command or hotlink for controlling operation of the graphics processing engine. In response to user selection of first data displayed in the second portion of the display, a supervisory controller analyzes the first data to determine if the first data includes at least one hotlink command. Upon determining that the first data includes at least one hotlink command, the supervisory controller identifies the hotlink command included in the first data and controls operation of the graphics processing engine to perform at least one graphics function according to the hotlink command included in the first data. The graphics function may be associated with at least one of the three-dimensional objects, a three-dimensional markup, a predefined view point, or a predefined animation.
