MIThril 2003: applications and architecture

In this paper we describe the MIThril 2003 wearablecomputing research platform. MIThril 2003 is a proven,accessible architecture that combines inexpensive,commodity hardware, a flexible sensor/peripheralinterconnection bus, and a powerful, light-weightdistributed sensing, classification, and inter-processcommunications software layer to facilitate thedevelopment of distributed real-time multimodal andcontext-aware applications.MIThril 2003 extends the previous MIThril modulararchitecture into the domain of large-scale wirelessgroup applications by leveraging the availability ofinexpensive Linux-based PDA hardware combined withinnovative open-source software and custom sensorhardware. We demonstrate the power and functionalityof MIThril 2003 by describing compelling real-worldwearable research applications created using MIThril2003 technology.
