Lilibeth’s Parade is a game made for the Global Game Jam 2017, in Goldsmiths, University of London, London, UK. The jam’s theme was “waves”. Made by Ciro Durán and Yole Quintero.

Inspired by Queen Elizabeth’s iconic salute, we built this gesture as the main mechanic of the game. We interpreted the theme “waves” as a verb rather than a noun.

In Lilibeth’s Parade, two players stand in front of a Leap Motion hand sensor, and must wave as the Queen to make their car progress towards the Westminster Palace Clock Tower. The first player who reaches the tower wins.

The game has the following components:

• A Leap Motion sensor. This is a sensor that can build a model of a hand (or hands) in real time. This allows us to detect the waving gesture.
• A PC. We would have like to used a Raspberry Pi, but as of the time of building this game, there were no Leap Motion drivers for the Raspberry Pi.
• An Arduino Uno with a screen shield. This is to display the state of the game, and show the winner.
• An Arduino Mega connected to servos. This is to show the players’ progress. This board is also connected to neopixels embedded in the tower to enhance the sense of progress.
• A cardboard model of the Clock Tower.

On the software side, all components are connected through a single Processing sketch. The sketch communicates with the Arduinos through the serial port, and with the Leap Motion sensor through the driver that comes with the Leap Motion SDK. There are Processing binds with the Leap Motion sensor.

During the jam we tried exploring other options, such as using OpenCV and a webcam to detect the hands through skin recognition. After a day of exploring this solution we realised that it would not take us to our desired result on time.
