Building an AR Magnetic Field Visualizer—The Vision and Challenges

In our previous post, we provided a rationale for why we believe using personal mobile devices (PMDs) to visualize real magnetic fields with sensor data is important. In this post, we take a look at specifically what we would like to accomplish, and the challenges that we are experiencing as we work our way to our goal. We propose the development and testing of new software utilizing AR frameworks for PMDs that will allow learners to visualize a 3-D magnetic field from multiple perspectives as their PMD moves through it. This software will utilize the new sensitivities of the recently-introduced AR frameworks to determine physical location of the PMD based upon both the inertial sensor unit

Building an AR Magnetic Field Visualizer—Rationale

Technology gives humans the opportunity to perceive physical attributes of the world that are completely invisible. Magnetic fields, for instance, are not directly observable, but being able to visualize them is important for understanding experiences as commonplace as transmitting radio signals to a car stereo system or as cutting-edge as doing atomic particle research. Personal mobile devices (PMDs) such as smartphones and tablets are enabled with sensors that could make the ability to visualize invisible fields a reality for anyone who has access to a PMD, including the 77% of U.S. adults ages 18+ who own a smartphone (Rainie, L. & Perrin, A., 2018). For the 92% of smartphone-owning U.S.
