 Dissertation  Problem and Objective  Reason for selecting  Case Study with Purdue University  Derived Communication Protocol  Test Case with Cal Poly University

 Problem A robust and reusable communication method does not exist to connect external simulation languages with a compelling and accessible client-server Virtual Reality Environments.  Objective Develop a robust and scalable communication method that connects external simulation languages with client-server Virtual Reality Environments

 While simulations are currently available in CVRES, the calculations required to execute these simulations bog down the system. A lot of server time is spent updating the actual environment itself  Implementing simulations using existing methods does not allow for quick changes

 Partnership Dr. Randy Rapp Associate Professor, Purdue University Disaster Restoration and Reconstruction Management, concentration Ex-military commander US-ACE  Application Simulate the phases of construction project excavation while allowing the students to make the selections and give feedback in response to their actions

 Task: A simulator for training individuals how to properly excavate a construction site.  Goal: Present the individual with questions relating to the sequential process of excavating a construction site and show them the how their answer effects the construction site.

 Dr. Rapp provided specifications necessary to execute the excavation training simulator, three project bid plans, and three soil types.  Task: A simulator for training individuals how to properly excavate a construction site.  Goal: Present the individual with questions relating to the sequential process of excavating a construction site and show them the how their answer effects the construction site.

 Process: Students are presented with a bid plan and soil type then asked the following questions:  What is the soil type described?  What type of slope should be used?  What is the volume of soil to be excavated? If all the questions are answered correctly, the construction site is excavated. If all the questions are answered incorrectly, the construction site is excavated improperly.

 Implementation Tasks Developed Project Flow Charted Preliminary Design Implementation of the project Project Testing

 This design allows for states to be manipulated or added in an easier fashion

 Partnership Hal Cal Poly Tech COINS  An abstract project bid training simulator  All information is abstract with no visual results or intermediate information except raw data.

 Game Rules Players bid on a project by selecting what method of completing the task they feel is best. Their bids are totally based on the CEU of the project.  A project costing x CEUs correlates to one appropriate method The user does not know if their selection is correct until the bid period is over

 Project Goal Develop a simulator to show the user what their selection of method will give them in the field.  Project Requirement Requires connecting to the COINS database and listening for a selection of method. When a method is selected a simulation is displayed so the user can see what their selection will yield before they actually make the bid.
