  1. Biofeedback in Virtual Reality applications and Gaming Bonie Rosario, Jr. Sebastian Osorio Tom Iancovici University of Massachusetts Lowell Intro to Biosensors 16.441.201 Prof. Xingwei Wang

  2. Outline • What is Biofeedback? • Tracking Brainwaves and Eye Movement • Measuring Heart Rate and Skin Conductivity • Applications • Timeline and Division of Responsibilities

  3. Research Topic Responsibilities • Tom Iancovici Brainwave Tracking (EEG) and Eye Movement Tracking - Theory - Hardware - Products in the Market • Sebastian Osorio • Measuring Anxiety (Heart Rate and Skin Conductance) • - Theory • - Hardware • - Products in the Market • Bonie Rosario, Jr. • Applications • - PTSD Treatment • - Anxiety Treatment • - Assistive Technology • - Next Generation Gaming

  4. What is Biofeedback? • Biofeedback = the technique of using monitoring devices to furnish information regarding an automatic bodily function, such as heart rate or blood pressure, in an attempt to gain some voluntary control over these functions[1].

  5. Technology • (EEG) Electroencephalography is the recording of electrical activity along the scalp produced by the firing of neurons within the brain[2]. - Method of Detection: - Detects: Wave patterns (i.e. Delta, Theta, Alpha, Beta, Gamma and Mu) and Event Related Potentials (P300, N200, N2pc, and more)

  6. An example of a Two-channel EEG amplifier Hardware Point of View An example of an EEG device prototype

  7. Commercial Product NeuroSky MindWave • Emotiv EPOC

  8. Measuring Anxiety and Tension • Skin conductance, also known as galvanic skin response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level.[3] • Heart Rate

  9. Commercial Product Wild Divine Iom ® Wild Divine Lightstone

  10. How Does This Work? V R I

  11. Using Lightstone In Half-Life 2 • Measurements of heart rate variable (HRV) • Skin Conductance Levels (SCL) • Changes In Game Environment • If you’re calm • If you’re nervous

  12. Other Applications PTSD Treatment via Virtual Reality Simulation Stress Management Tool Neuro-headset as Human Computer Interface

  13. Timeline • 3/22/11 - Research EEG and Neuro-headset design • 3/22/11 - Research Heart Rate / Skin Conductance Biosensor Design • 3/22/11 - Research Other Novel Hardware • 4/12/11 - Propose Design for Novel System that Combines All Types of biosensors • 4/12/11 - Present Findings on Hardware in Class • 4/12/11 - Write Literature Review Paper • 5/03/11 - Finalize our Design and Determine Feasibility • 5/03/11 - Present Overall Conclusions in Class • 5/03/11 - Finalize Literature Review Paper
