A Heart of Tin is a virtual reality adventure game based on The Wizard of Oz. It is designed to help teach players how to effectively support those with depression. In the game, the player is a traveler on the yellow brick road whose travels are interrupted at a small village when trees block the road. In order to continue their journey, the player has to convince the Tin Man to clear the road. Unfortunately, he's suffering from depression, and the player has to interact with him and his neighbors to support him through his troubles, making dialogue choices and interacting with objects in the environment to help support him. As the player finishes the game, their performance is evaluated, and feedback is given in order to teach the player areas in which they could be more supportive. The project received oversight and direction from multiple subject matter experts, including therapists and doctors of psychology. The game is intended to be used in a clinical manner, teaching while still engaging to the audience. Virtual reality was used in order to give the player a more personal connection with the characters, and to emphasize the value of proximity and physicality in support.
