The purpose of this research effort is to design a generic architecture for collaborative haptic, audio, visual environments (C-HAVE). We aim to develop a heterogeneous scalable architecture for large collaborative haptics environments where a number of potential users participate with different kinds of haptic devices. This paper begins with a brief overview of C-HAVE and then proceeds to describe a generic architecture that is implemented over HLA/RTI (High Level Architecture/Run time Infrastructure), an IEEE standard for distributedsimulations and modeling. A potential electronic commerce application over C-HAVE is discussed.

The paper examines the technology of composability in simulation systems. Composability refers to the ability of a simulation to be flexibly configured to adapt to a range of missions, scenarios, simulation models, hardware environments, and security configurations. Composability confers maximum flexibility to the usage of the simulation. simulation composability is a requirement of the Joint simulation System (JSIMS). JSIMS is currently being developed by the US Department of Defense and is intended To deliver commander and command staff training. The paper examines simulation composability from the JSIMS perspective and explores the overall technical approach and the related issues.

A new approach to handling battle simulation lethality is presented. In this approach a single server provides standard DIS damage states to entities fast enough for most realtimeapplications. Benefits include freeing DIS simulations from the burden of maintaining damage state tables, lower DIS pre-exercise preparation, and Easier scenario configuration as a whole. These benefits are realized primarily because efforts to prepare and maintain the vulnerability data pertaining to the exercise are not duplicated.

This paper discusses the development of a Generic Interface that will enable traditional non- object-oriented applications to become HLA compliant. By providing Sol both DIS and HLA, the proposed interface can support not only new but existing or legacy software applications as well. in addition, the interface will make it easy for simulationapplications that today require a standard networking protocol as a backbone to use DIS components in place of corresponding HLA components as air interim solution. After a general overview of the concept of a Generic Interface, the paper then proceeds with a description of the interface components and how they can be used to harmonize the various applications involved in a simulation.

The High Level Architecture (HLA provides the specification of a common technical architecture for use across all classes of simulations in the US Department of Defense. It provides the structural basis for simulation interoperability. The baseline definition of the HLA includes the HLA Rules, The HLA Interface Specification, and the HLA Object Model Template. The HLA Rules are a set of 10 basic rules that define the responsibilities and relationships among the components of an HLA federation. The HLA Interface Specification provides a specification of the functional interfaces between HLA federates and the HLA Runtime Infrastructure. The HLA OMT provides a common presentation format for. HLA simulation and Federation Object Models. This paper provides a description of the development of the HLA, a technical description of the key elements of architecture, and a discussion of HLA implementation, including HLA supporting processes and software.

Simulator time-delays (latencies) are an important factor in the simulation world. In research and/or training, an), high-fidelity simulation is adversely affected by latencies. The simulation Network Analysis Project ((SNAP) was developed to investigate these latencies. The SNAP system can measure latencies between vital points (stick input, state variables, visual displays, and the Network Interface Unit - or any other points of interest) in a stand-alone simulator and between networked simulators. Data correlation is accomplished via Global Positioning System (GPS) time-stamping. This paper will report on the findings from past latency measurements and key lessons learned. Factors affecting latency: such as network configuration (hardware and software), simulator modifications;and network loading will be discussed.
