3Preamble Overview (Meeting February 16th, 2009)ProblemA robust and reusable communication method does not exist to connect external simulation languages with the compelling and accessible client-server Virtual Reality Environments.

ObjectiveDefine a communication language protocol schema between a simulation language and a client-server Virtual Reality Environments Test the robustness of the developed communication protocol.

4Preamble Question 1 from Pre-prospectusWhat is the relative performance of calculations in Virtual Reality Environment vs. Object Oriented Simulation Languages?Experiment: Compare Second Life, LabVIEW and C++ for sample calculation

For all numbers i between 1 and 1,000,000If i is odd { sum += i }ResultsSecondLife (LSL): 24.708785 secondsLabVIEW: 0.3314 secondsC++ (computer/orca): 0.0148 seconds/0.007 seconds

PreambleQuestion 2 from Pre-prospectusWhy use LabVIEW as a simulation language?Many potential collaborators are not expert programmers LabVIEW presents a simple visual interface and is widely used in engineering and operation fields.LabVIEW is the most widely used Data Acquisition language long term it will be very useful to have Simulations+VR which can have various devices added easily.LabVIEW is sufficiently fast for 15-30 world refreshes per second and if speed becomes an issue additional faster modules in other languages can be added using LabVIEW as a data integrator and communication hub.

6Preamble Questions 3 from Pre-prospectusAre there other examples of large simulation in Client-Server VR?All examples found were simply visualizations without significant simulation

7Preamble Questions 4 from Pre-prospectusWhat will be the impact of your research?Allow for faster, more complex, and scalable virtual reality environments to be developed. Permit the extension of these hybrid simulations to be extended using the object-oriented functionality.Could result in larger, more complex, and scalable virtual reality simulations to be developed in a large number of fields including construction, medical technology, education, and so forth.

10BackgroundVirtual Reality Environments (VREs)Are used for decision making, design, training and various other purposes.Must maintain breadth (sensory dimensions) and depth (quality) of information to submerge the user into the VRE.

11BackgroundSimulationsUseful for testing products or methods.Base models can be developed and interactions can predict the outcome.

12BackgroundCommunication ProtocolSet of rules for data to be transferred between communicaiton channels.Main focus in developing communicaiton protocols is to improve latency as well as adding new communication protocols.

16ProblemA robust and reusable communication method does not exist to connect external simulation languages with the compelling and accessible client-server Virtual Reality Environments.

17ObjectiveTo develop a robust and scalable communication method that connects external simulation languages with client-server Virtual Reality Environments.Two sub-objectivesSub-Objective 1: Define a generalizable communication layer between an external simulation language and a client-server Virtual Reality Environment (VRE)Sub-Objective 2: Test the robustness and scalability of the proposed design a case study with several components.

18Objective (Cont.)Sub-Objective 1: Define a generalizable communication layer between an external simulation language and a client-server Virtual Reality Environment (VRE)A mapping between the finite state machine definitions of the generalized simulation language(1,S1,s01,1,F1) and the event-driven state machine of the client-server VRE (2,S2,s02,2,F2).

19Objective (Cont.)Sub-Objective 2: Test the robustness and scalability of the proposed design a case study with several components.The communication protocol as developed in sub-objective 1 will be tested using a simulation language such as LabVIEW, a VRE such as SecondLife, and a motivational large scale simulation problem.
