While coarse-grained indoor location estimates may be obtained quite easily (e.g. based on WiFi or GSM), finergrained estimates typically require additional infrastructure (e.g. ultrasound). This work explores an approach to estimate significant places, e.g., at the fridge, with no additional setup or infrastructure.
