Design and implementation of a virtual electronic dart with a tablet system

In this design, we propose a virtual electronic dart which contains a microcontroller, a tri-axis accelerometer and a Bluetooth module. The players only need to wear a ring and a bracelet to swing this virtual electronic dart in the air. The controller will transmit the space coordinates of the virtual electronic dart to the specific tablet that calculates the hit location of the dartboard by using the flying path of the projection equation. The results are then displayed in the tablet´s screen.
