چکیده
This paper describes a method for collecting real-time energy consumption statistics for a custom wearable system. We describe an implementation of hardware and software which provides detailed trace data for every major subsystem of a wearable computer, including the microprocessor, memory, and I/O. This design is entirely selfcontained, requires no external instrumentation, and imposes low computational overhead. By using a comprehensive power monitoring scheme, wearable system designers can better understand the energy/performance tradeoffs implemented by applications, communications, and human interaction devices.
