 Cardiac Arrest Video Game Design by: Oskar Otoya Drew Dopson Chris Ho Kekoa Taitt

Problem Statement  Most video games today are one-dimensional in terms of user interaction (don’t rely on user biofeedback within the game itself).  Our objective is to design an inexpensive video game that incorporates real-time feedback from the player in order to fully immerse the player into the game.

Project Background  Boston Children’s Hospital created a video game to teach kids with anger issues to control their emotions. Asteroids- like game that disables your ability to shoot if your heart rate exceeds a certain limit.

Architecture

Innovative Solution  Our goal is to extract biofeedback from a heart rate monitor attached to the player and use that data to modify the video game in real time.  The game will become more or less intense based on the feedback it receives.  Creates a solution for people who become terrified more easily (higher heart rate = less intense).

Unity Specifications  Uses C# implementation to program game logic  Features  Asset – objects (even imported from blender), sounds, cameras, character actions, etc.  Prefabs – like templates – can create once and use it in multiple sections  Scene – like a level. Where you put assets/prefabs and also design the scene/level  Has many other features. This is just scratching the surface of Unity.

Blender  Open source 3D modeling software used for creating visual effects, objects, etc.  Python scripted for tool creation, importing/exporting formats, etc.

Major Technologies  USB Heart Rate Monitor

I/O Implementation of Heart Rate Monitor  Unity has a built-in library specifically for Input/Output from serial ports.  Ex. Using a statement such as:  SerialPort stream = new SerialPort(“COM4”, 9600);  COM4 is the port your want to access  9600 is the data transmission rate in bps (standard for most devices)

Challenges and Uncertainties  Becoming proficient with Blender and Unity in order to use them collaboratively  Integrating heart rate monitor with Unity  Lack of personnel given the time allotted and scope of the project

Expected Outcomes  Be able to successfully incorporate a heart rate monitor into a fully functional video game  Become more proficient with Unity and Blender  Have a marketable product that is cheap and entertaining

Project Plan  Blender software to create individual objects  Unity software to create game and integrate all objects together into a single program  Use Unity to extract data from heart rate monitor during game execution  LOTS OF TESTING!!!

Component Procurement  Purchase USB Heart Rate Monitor - $20 plus shipping  Unity and Blender software download - free

Conclusion  Although the gaming industry has begun to involve human interaction, if used at all, biofeedback has been very limited.  We hope to revolutionize and create a stepping stone for the use of biofeedback and change the way people interact with video games.
