AR Mural

  WINLAB Summer Internship 2024

  Advisors: Ivan Seskar, Jennifer Shane

  Group Members: Jovana Lekic, Nima Fallah, Nishi Agrawal, Suhani Sengupta, Sachin Kandan

Project Description

This project aims to create a collaborative augmented reality application that will allow remote users to create a virtual mural collaboratively. This project will be made using the Unity game engine and deployed to AR platforms such as Microsoft Hololens.

In addition to creating the software that will manage the generation and rendering of the mural, another important component of this project is designing an infrastructure that will allow for very low latency collaboration. If time allows, one of the end goals of this project is to deploy it using an "edge cloud" architecture using the OpenAR Cloud project.

Students should get started with this project by familiarizing themselves with the Unity game engine and Hololens development tools.
