  Multi‐User Virtual Environment (MUVE) for conducting Airplane Evacuation drills using Gaming Metaphor
Virtual Reality (VR) training has been used for training and education for many years in military and medical fields. We have used game creation as a metaphor in creating an experimental setup to study evacuation behavior for an airplane. Our objective is to create an experimental design setup for assessing human behavior in emergency evacuation of an aircraft among a team of players in a game set in a virtual environment. Also, our aim is to create a multi user environment to allow participants in different geographical locations to connect and be able to interact in the VR environment.
  Collaborative Virtual Reality Environment (CVE): Virtual Campus Tour and Virtual Evacuation Drills of BSU Campus using Corner Cave and Oculus Rift
The use of multi user virtual reality environment training and virtual tours have been increasingly recognized an as alternative to traditional real-life tours for university campuses. Our proposed application shows an immersive collaborative virtual reality environment for performing virtual online campus tours and evacuation drills using oculus rift head displays. Immersive collaborative virtual reality environment also offers a unique way for training in the emergencies for campus safety. The participant can enter the collaborative virtual reality environment setup on the cloud and participate in the evacuation drill or a tour which leads to considerable cost advantages over large scale real life exercises.
  Mult-User Virtual Environment (MUVE) for Conducting Subway Evacuation Drills using Unity 3D and Oculus Rift
People catch the train to get around the city for many reasons, and with so many people using subway trains, emergencies are bound to occur. A virtual multi-user environment can be used to find flaws in evacuation procedure and show passengers a better way to avoid danger in an emergency. Creating a live emergency with real people would be dangerous and unethical. However, creating a virtual emergency with real people is safe and efficient. We have used game creation as a metaphor in creating an experimental setup to study evacuation behavior in a Virtual Reality Multi-User Subway Environment.
  Megacity: A Collaborative Virtual Reality Environment for Emergency Response, Training, and Decision Making
We have used game creation as a metaphor for creating an experimental setup to study human behavior in a megacity for emergency response, decision-making strategies, and what-if scenarios. Our proposed collaborative VR environment includes both immersive and non-immersive environments. The participant can enter the CVE setup on the cloud and participate in the emergency evacuation drill, which leads to considerable cost advantages over large-scale, real-life exercises. We present two ways for controlling crowd behavior. The first defines rules for agents, and the second provides controls to the users as avatars to navigate in the VR environment as autonomous agents.
  Urban Emergency Response in a city using Multi-User VR Environment
The goal of this project is to create a multi-user helicopter training simulation that will aid in the efforts of treating wildfires. The simulation includes various scenarios immolating real-world instances. Real-world instances are in place to develop alternative techniques that may be applied to real life situations. It is anticipated that the user will gain skills and knowledge in the virtual environment that they will then be able to apply to the real world due to the sense of presence and realism a virtual environment can provide. The simulation may be used for both training and educational purposes. The application will track user efficiency and decision making strategies.
  Game-theme based instructional modules for Computer Science Students in VR
The goal of this project is to create course curriculum modules for computer science and mathematics students. Engineering and Mathematic courses are typically considered as difficult by college students and exhibit high failure rate. Due to the complication and abstract nature of computer hardware, it is a challenge for students to understand the principles and concepts related to computer organization.  The aim is to create Virtual Reality course educational curriculum modules with more inquiry based problem-solving activities and hand-on experiences based on Virtual and Augmented Reality. We will create modules for arrays, linked list, memory mangament, trees, binary search, stacks, queues, etc.
  Collaborative Virtual Reality Environment (CVE) to Improve Patient Experience in Healthcare
Our Collaborative Virtual Reality Environment (CVE) project goal is to improve patient experience in healthcare. We use virtual human technology to create realistic characters as avatars and uses natural language, non-verbal behavior and realistic scenarios for both military and non-military issues to train clinicians. This application has a dual purpose. The simulation may be used for both training and educational purposes. The goal of this multi-user VR Environment (MUVR) is to track user efficiency and decision making strategies. Multiple agents are necessary for this environment because it will promote communication, collaboration, and will enhance the decision making process.
  Collaborative Virtual Reality Environment (CVE) Real-time Emergency Evacuation of Kiss Nightclub Fire
The purpose of this project is to re-create a past events that occurred during the tragedy in a nightclub in Brazil. It utilizes Unity 3D assets and applied mecanim animations to replicate realistic experiences. It also utilized Photon Unity Networking to allow the use of multiple user capability. Our hypothesis is that the CVE would allow learning from existing disasters to prepare for similar events. The proposed CVE should decrease safety risks as well as allow users to evacuate safely during emergency responses.
  Mobile Augmented Reality Application (MARA) for Campus Tour using Samsung Gear VR
Our current application shows the interactive virtual campus tour using Samsung Gear VR head mounted display. We have used Unity 3D gaming engine and vuforia pluggin for developing the campus environment. The environment is tested using Samsung Gear VR and Samsung Galaxy S6, and Samsung Galaxy S6 edge. The BSU university campus 3D environment is designed to give the user a complete immersive feeling of the campus. We hope our contribution helps in developing more interactive virtual reality campus environments.
  Android App for Emergency Response and Surveillance
The goal of this project is to develop an android application for emergency surveillance at BSU by using google latitude and longitude to determine the location of the user. It will provide safety decision making system for a school/university. We are using Eclipse IDE to add the google map with normal and satellite view into the application with a valid API key. We are also combining the geo-location and location manager with the map to get the current location of the user. Currently we are working on tracking multiple users and integrating augemtned reality markers on the campus map.
  Mobile Augmented Reality Application (MARA) System for Navigation, Learning and Campus Safety
The goal of this project is to use ARTtoolkit to create a emergecny response system to help people evacuate a building. The system that give a visual represrentation of a building in 3D space, allowing people to see where exits are in the building. With FLARToolKit, an AS3 port of the Open Source library ARToolKit, one can detect a marker from an input image and calculate the camera position in 3D space. Our proposed solution would include putting the markers at key spots in the building, such that the user can use their smart phones to view the 3D representation of the building and exits. The proposed systems will use GPS data to generate a geo-spatial representation of the university campus environment that can be navigated and manipulated through augmented reality.
  Virtual Reality Classroom: A Collaborative Educational Virtual Learning Environment
This project presents a Virtual Reality Classroom that is similar to second life. TheVR environment could be used as an actual virtual classroom where teachers can interact with students and deliver the lecture. The online virtual classroom is developed so that students can interact with each other as well as the instructor. Teachers can also use this server/client feature for delivering lectures in an online virtual environment.
  Mobile App for increasing Productivity and Health at Workplace
Mobile devices and apps provide many benefits for users, perhaps most significantly is the increased access to point-of-use tools. Providing simple exercises with the help of mobile apps allows the user to access and practice exercises at the work place.This project presents a mobile work place fitness application which can increase the productivity and health of the users at the workplace. The proposed mobile application provides an account profile facility to check daily exercise activities and help users to be productive at work. We have added security to the user accounts and profile features that will secure user data and personal health-related records. Our contribution lies in our approach to create a user specific customizable exercise plan in order to improve the health and productivity of the users at their workplace.
  Virtual City: Crowd behavior and traffic intersection problem
We are developing a crowd behavior capability in a virtual city where there are traffic intersection junctions for people to cross over the road. We will generate a wide variety of civilian individual and group behaviors at differing levels of fidelity. Our simulation will consist of autonomous virtual human agents walking on the side walk in the virtual 3D environment. Agents will have 3D graphic body representations. They will be able to perform certain low-level actions like playing of pre-recorded animation sequences such as gestures or walking to specified location.

Using Genetic Algorithim and Neural Network for learning and adaptive behavior in a goal finding application

The goal of this project is combining Genetic Algorithm (GA) with Neural Networks (NN) to explore how intelligent agents can look for exits during an evacuation. The agents have the capability to adapt their behavior in the environment and formulate their response by learning from the environment. Our approach focuses on modeling individual behavior as well as group behavior. Individuals constantly adjust their behavior according to the dynamic factors in the environment. We are developing crowd-modeling and emergency behavior modeling capability in a goal finding application. This project examines an intelligent agent-based evacuation that can help plan emergency evacuations, run numerous event-driven evacuation scenarios, support research in the areas of human behavior, and model the movement of responders and security personnel. The result of this simulation was very promising as we are able to observe the agents use GA and NN to learn how to find the various exits.

Past Projects

Modeling and simulation of emergency response and hazardous events for aviation safety

In this project, we simulate evacuation behavior in an aircraft using a crowd component. In passed years, there has only 2D simulation and this application can be used by airlines to simulate emergency scenarios without the use of live actors. This will allow airlines to run multiple simulation under a variety of conditions which will save time and lower costs. The application can also be adapted and expanded to other industries.

The students will gain experience by using state-of-the-art VR equipment, software and technologies including 3D Wall, Head Mounted Display (HMD) that allows students to visualize complex data in three dimensional (3D) objects, working in 3D space to solve complex spatial problems, and conducting novel research through course work and research experience in the laboratory.

Simulation and Evacuation of Dulles Airport Passengers in Emergency Scenario

The projects goal is to present the Washington Dulles International Airport (IAD) in a Virtual Reality enviorment. The airport is situated in Chantilly, Virginia, USA. This application can be used for training a future pilot. It could also be used as an educational and training tool for depicting emergency scenarios. We will explore emergency scenarios both inside and outside the airport. Inside the airport the behaviors are evacuation, collective, cooperative, and selfish behaviors. Outside the airport we will model and simulate: Precautions during flight take off, Plane taking-off on a runway with snow, Undesirable object like bird comes in the way of flight, Bird hitting the engine during take-off, etc.

  Simulating and Modeling of Bowie State University's Library for Navigation and Evacuation
The main goal of this application is to aid the visitors and to present VR as a tool for educational and training. This project presents the simulation and modeling of a Bowie State University library building in a virtual environment. The development of virtual reality environment makes it possible for a user to understand and observe multiple paths that an agent would observe during navigation and evacuation. This environment can be used via the web or through a physical kiosk placed at the entrance of the building. This application can also be used to simulate the evacuation behavior inside the building.
  Rovio Robot for Surveillance in Emergencies
Rovio is a Wi-Fi enabled mobile webcam that lets you view and interact with the environment through streaming video and audio. Rovio can be remotely accessed from PC or Mac, cell phone, smartphone, PDA or even a video game console with an internet connection. Our research focuses on dispatching rovio to the threat location to collect data and exchange messages with other mobile/ static sensors. Our work also focuses on wireless mesh network (WSN), intelligent fuzzy interface system, real-time video stream data fusion, background modeling and anomaly detection.
  Modeling and Simulation of Crowd Behavior

Many research and social interaction aspects of crowd behavior are beyond the reach of available tools. The VR environment is able to adapt for specific design situations and provide insight to current perspective as well as what-if questions. Our hypothesis is that mutual concern, helping, and co-ordination will more likely occur when crowd members share a common identity. The selfish behavior associated with 'mass panic' may occur in evacuation if there is no shared identity. Our hypothesis is that the visualization studies support the conclusion that, where there is a strong sense of collective identity, there will be mutual concern and helping.

  Evacuation Simulation and Embedded Videos
This project presents evacuation simulation of a school building using virtual reality. It is well known that crowd stampede is one of the most disastrous forms of collective behavior caused due to panic. It leads to fatalities as people get trampled and crushed as they fall. The application presents a school building environment with several classrooms with students, teachers, chairs, televisions, walls, doors and tables.This simulation aims to aid the visitors in navigation within the building.
  Virtual Reality Museum as a Tool for Learning and Education
The ability of Virtual Reality (VR) to explain the principles of design, manufacturing and business far surpasses that of books. Virtual environments (VE) provide facility for experiential learning by allowing the students to explore the VE at their own pace and interact in real time. Game creation is used as a metaphor for early design education. The VRML Museum project was conceived with the interest of informing the public about the evolution of current manufacturing systems.
