Current Students: Pranay Rajeev, Dexter Ballerda and Diliorah Arah

Past Students: Usha Govindaraju

Status: Current

Augmented Reality (AR) is a relatively new technology that blends real-world data and computer-generated graphics in real time, blurring the line between reality and virtual by enhancing what we perceive. It opens a whole lot of possibilities in many fields, from medical to engineering, including evacuation, navigation, network security, and learning.

 

Project 1: M-Evac: Using ARToolkit to create an emergency response system for library evacuation

 

M-Evac is a AR application that allows you to view the 3D augmented reality scenes. 3D models are overlaid on the real world as seen through a mobile or computer’s webcam, making them appear to part of the surrounding real environment. M-Evac uses marker-based camera tracking such that the 3D models appear attached to physical printed markers. We show how the application is able to display a 3D model of the building using markers and web camera. The system gives a visual representation of a library building in 3D space, allowing people to see where exits are in the building through the use of a smart phone. M-Evac is a Mobile Augmented Reality Application (MARA). The MARA will enale enable policymakers and first-responders to evaluate evacuation strategies and mobile device usage during evacuations. With Open Source library ARToolKit, one can detect a marker from an input image and calculate the camera position in 3D space. M-Evac will supports the following features:

• scaling models
• loading 3d models in the android mobile
• positioning models relative to real markers
• user customizable tracking patterns
• windowed or full screen viewing model
• support for a variety of camera image resolutions

Project 2: Augmented Reality Sytem for Navigation and Learning for Campus Safety

Area: Network Middleware, Location Based System, Mobile network, Security and Privacy for AR Systems

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. Users can manipulate ARToolKit markers augmented by 3D BSU campus map with tagged locations containing images, 3d models, video, audio, and text. 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. We are integrating GPS, google maps, video to be integrated into the system. We propose to do the following:

  • Developing a network middleware for Mobile Augmented Reality Application (MARA) that can be applied to the area of large scale campus safety application.
  • Developing a Location Based Augmenetd Reality System (LBARS) for navigation and learning on campus. The proposed location based surveillance system will provide customized real-time information by incorporating decision-making strategies to guide people during emergencies. Incorporate special instructions based on external threat condition like smoke, biohazard for the safety of occupants.
  • Develop Security and Privacy for the MARA Systems. Devices providing immersive feedback can be used by malicious applications to deceive users about the real world.
  • Decision Support System: The proposed tool will recommend occupants regarding the various safety measures to avoid the threat and give customized real-time evacuation communication plan for the course of action to be taken by each user to reach a safe location.
