As part of the Living Observatory ecological sensing initiative, we've been developing new approaches to mobile, wearable sensor data visualization. The Tidmarsh app for Google Glass visualizes real-time sensor network data based on the wearer's location and gaze. A user can approach a sensor node to see 2D plots of its real-time data stream, and look across an expanse to see 3D plots encompassing multiple devices. On the back-end, the app showcases our Chain API, crawling linked data resources to build a dynamic picture of the sensor network. Besides development of new visualizations, we are building in support for voice queries, and exploring ways to encourage distributed data collection by users.
