Journey Controller (Hongxu Li)

Description:

The Journey controller is a wearable controller. It's made of three pieces: a hood, a cape, and the motion controller chest band.  The game Journey emphasizes the isolated loneliness feeling.  The concept model of the controller is to give the player a chance to be the character in the game. Covering the player from head to toe and using motion control create a more immersive experience of the gameplay than its original control. The inputs of the controller are six body motions: leaning forward, leaning backward, tilting left, tilting right, tipping toes, and voices. The output of the controller is corresponding character movements. The mapping of the controller is to map the accelerometer and sound sensor readings of the CPE to the key pressing function which controls the character’s movements. The hood and the cape are the signifiers of the controller. They indicate the purpose of the controller is to dress up and play as the character in the game. The feedback mostly reflects on the character’s movements and whistles in the game. The controller affords a stronger immersive gameplay experience to create a sense of the connection of motion and emotion between the character and the player.  What other signifier and feedback could be added to the system to make the controller easier to understand?
