Project 1: Vectors in Space (VIS) app
Goal: The goal of the app is to improve undergraduate students’ learning of three-dimensional vector concepts as encountered in engineering mechanics (Statics).
Platform: Magic Leap 1 Headset
Developers: Rachel Tomasetti, Marcos Morales, Adam McMahon
Summary: VIS introduces students to vector concepts and vector operations. While using the app, students can explore these concepts in their own space by “walking around them”.
Module 1 “Introduction to Vectors”: Using a hand controller, students first create a reference coordinate system by placing the origin anywhere in their environment. They can "draw and connect" points using a hand controller to create vectors in 3D space, then toggle between views of the corresponding (i) vector components, (ii) unit vector and its components, and (iii) three directional angles. Students can walk around the stationary vector and view it from multiple positions and perspectives, thus, enabling them to visualize and understand these relationships.
Module 2 “Vector operations”: Like the first module, students first create a reference coordinate system. Then they create two vectors and choose to perform the addition, subtraction, cross product, or dot product operation.

Project 2: AR Stairs
Goals: 1. Compute the bending moment in the structure due to assumed weight of moving people, 2. Visualize the change in moment intensity on the stairs structure in real time, 3. Engage students as either hands-on users (viewers) or active dynamic loads.
Platform: Magic Leap 1 Headset
Developers: Mert Okyay, Berk Basarer
Summary: The app utilizes real-time image recognition to detect people on the stairs and automatically and continuously calculate the bending moment intensity throughout the stair case. The moment intensity is shown as changes in color from green to indicate low intensity to red for high intensity.

Project 3: Distributed Forces
Goal: To enable students to visualize the distributed forces of objects acting on a platform.
Platform: Magic Leap 1 Headset
Developers: Rachel Tomasetti, Adam McMahon
Summary: This app enables students to define a simply supported beam and model the forces of objects on the beam as either a rectangular or a triangular distributed load. The app then calculates the reactions at the supports.

Project 4: Newton’s Experience
Goal: To enable students to explore the sliding behavior of objects on an incline due to friction..
Platform: iOS devices
Developers: Drea Gonzalez, Marcos Morales, Jose Enrique Cardenas Reinaldo
Summary: The app starts by asking the user to select a space in their environment to place a virtual inclined platform. Then a virtual cube is placed on the platform. The user can change the inclination angle of the platform, the material of the platform, and the material of the cube. This allows the students to explore how the different coefficients of friction can change the sliding behavior of the cube. The user can also add an external force acting in the direction opposite of the sliding motion.
