I challenged to work with an array of mini vibration motors and wireless local networking. The goal of this project is to create an immersive AR interactivity by generating haptic feedback of the virtual objects interacting with a physical desk. The user feels the vibration of the AR ball bouncing on a table through the haptic device. Every time it bounces, a signal is sent wirelessly to the main PC, which is sent serially to Arduino to activate motors. The future step is to more precisely activate the array of motors by computing the level of vibration based on the locations of the AR objects and the device.
