Proximity Sensing for Contact Tracing
share
The TC4TL (Too Close For Too Long) challenge is aimed towards designing an effective proximity sensing algorithm that can accurately provide exposure notifications. In this paper, we describe our approach to model sensor and other device-level data to estimate the distance between two phones. We also present our research and data analysis on the TC4TL challenge and discuss various limitations associated with the task, and the dataset used for this purpose.
