PEARL (Probing Entity Aggregation in Real Life) program aims to probe the interaction among people with helps of mobile phones and BlueTooth technique. With thousands of volunteers joining in the program, we can simulate the real social contact network very well, so as to give exact prediction on TB transmission, and so on.
The following map shows the quantity of volunteers in certain dates. Note that there are many overlapping counts due to volunteers' movement.
