Develop a system that can capture a video with 360 o coverage and wirelessly transmit that video to a remote base station in real-time. 2/24

There does not exist a solution which satisfies all of the following requirements: Simultaneous 360 o video capture Wireless transmission Real-time video feeds Inconspicuous design Portable design 3/24

Project Plan Design Document Physical Prototype of system Documents describing testing of various components and reasoning behind design decisions Results of testing the final prototype 4/24

Possible Uses: Endless Any environment in which a head piece of some kind is used Intended Use: Military Application Used for training exercises and combat scenarios Intended Use: Commercial Real Estate Used for virtual tours of property development 5/24

Technology Assumptions Commercial Cameras Commercial Transmitters Network Protocol Hardware and Software Our Assumptions have remained constant throughout our research and design process. 6/24

Capability of video capturing with camera The cameras must be able to capture 360˚ horizontal coverage. Capability to transmit video signals System must be able to wirelessly transmit all video feeds over a range up to meters. Video streaming must be as close to real-time as possible. Capability to receive and display video footage System must include a base station with software to display the collected video feeds. Mobility of power supply Battery must last 4-8 hours under standard operational load. Battery must be small and light enough to carry and wear. 11/24

Wireless n Dual Band Optimal Bandwidth of 300 Mbps Meets the required range of meters USB 2.0 interface Wireless n Dual Band Router 17/24

For purposes of testing hardware components, we will start with a simple VLC client. If time permits, we may build a simple client interface. However, this is not required as part of our project, and an advanced interface will likely be designed by a graduate student at a later date. 18/24
