 Project overview  Block diagram  Design challenges  Individual contributions  Project demonstration  Questions / discussion

 The proposed project is a mobile brain-computer interface  Computer applications will be presented to the user on a head mounted display  The user will navigate the device though eye gestures detected by an electrooculogram  The user will be able to select different application by increasing their level of concentration measured by a NeuroSky Mindwave EEG  Motivation behind device development  Develop a new and unique mobile computing platform  Develop a mobile computing platform that is operable by both the physically disabled and non-physically disabled  Design a project that appealed to the professional aspirations of each team member

 Making the system completely mobile  All components were chosen to be with size and power consumption in consideration  Acquisition of bio-potential signals  EOG designed in modular form, consumer grade EEG  Software optimizations for smaller processor  Multi-threading, compiler optimizations  Converting bio-potential signals into usable information  K-nearest neighbor algorithm, EEG selection algorithm
