Project Overview

▪ 2 player game ▪ Objective of the game is to use your hand motions to control a gyrosphere, which will be used to attack other player’s gyrosphere. ▪ Whoever knocks the other players gyrosphere out arena, wins ▪ Two Leap Motion Controllers tracks each player’s hand gesture which gets decoded into motion commands by a custom designed microcontroller and sent via a transmitter to the receiver inside the Gyrosphere
