The telepathic phone: Frictionless activity recognition from WiFi-RSSI
TLDR
We investigate the use of WiFi Received Signal Strength Information (RSSI) at a mobile phone for the extension of the environmental perception of a mobile device as well as for the interaction with touch-free gestures. Expand

An Alignment Approach for Context Prediction Tasks in UbiComp Environments
TLDR
The authors detail the alignment prediction approach-a time-series-estimation technique applicable to both numeric and nonnumeric data-and compare it to four other prediction approaches to determine context-prediction accuracy in ubiquitous computing environments. Expand

Joint localization and activity recognition from ambient FM broadcast signals
TLDR
We use the RF-channel as a sensing source to jointly detect locations and activities of individuals by monitoring peculiarities of RF-based features induced by these very activities. Expand
