  2. Project Overview • The proposed project is a mobile brain-computer interface. • Consists of 3 major subsystems • An EOG system to navigate a head-mounted display • An EEG to interact with applications on a head-mounted display • A single-board computer to generated the augmented reality environment • Each subsystem varies in complexity and has it’s own unique power requirements which results in a variety of safety and reliability constraints to account for.

  4. Component Failure Analysis • dsPIC Microcontroller (dsPIC33EP512MU810) • Most complex component that did not come on a premade board (unlike the FPGA, Single-Board Computer Processor and the Neurosky TGAM1 Module) • Switch-Mode Buck Regulator (LT1374) • Has more extensive performance requirements than any other regulator in our entire system • Analog-to-Digital Converter Module (ADS1210) • Most complex component in the EOG subsystem

  8. FMECA & Criticality Levels • High: Could potentially injure the user • Medium: Renders the system inoperable (no longer fulfills all of the PSSC’s) • Low: Inconvenience to the user, but the system still fulfills all of the PSSC’s

  9. Project-SpecificSuccess Criteria • An ability to encode/decode data packets from a NeuroSky EEG. • An ability for a user to select applications based on signals from a NeuroSky EEG. • An ability for a user to navigate between different applications on a display using EOG signals. • An ability for the system to interactively train the user to effectively operate the device. • An ability to display a live video stream from an external camera module, and integrate applications into the video system.
