In cities and crowded areas around the world, space is becoming an increasingly valuable commodity. Office building and university administrators, particularly, have an increased need to optimize room usage. With Utileye, we aim to directly address this problem by creating a battery operated device that can detect room utilization over a sustained period of time. The development of Utileye involved a significant embedded systems component, a custom PCB, and a user-facing website for monitoring and configuring devices. Beyond the technical implementation, we also developed a business plan designed to strongly position Utileye in the existing marketplace.
