The Future Cities Crowdsensor

João Rodrigues, Vítor Ribeiro, Ana Aguiar, João BarrosFEUP

What is a crowdsensor?

• Leveraging the power of the crowd• Use people as moving sensors to gather data

• Smartphones are a ubiquitous platform with many connectivity possibilities– 22% of the world population by the end of 2013

• Business Insider Intelligence, Dec 2013

– 39.6% of mobile phone users in Portugal• Marktest, Aug 2013

– 50% of the 15-24 age group• Marktest, Aug 2013

– These figures are growing

• Modular and stable mobile sensing platform– Application for Android OS– Cloud storage– Visualisation platform

CrowdSensor

SenseMyCity App

• Internal Sensors– Location: GPS, Network– Motion: accelerometer,

gyroscope, magnetometer– Connectivity: WiFi, cellular– Environmental: temperature,

pressure, humidity

• External Sensors– On-Board Diagnostics (OBD)– Vital Jacket (ECG)– Zephyr (heart rate)

Back and Frontoffice

• Storage and visualisation backoffices

• Data collection and storage following data protection guidelines– Informed consent– Privacy– Data ownership

Where is more data collected

Where do participants spend more time

What to do with the data?

• Available algorithms – Calculate mobility pattern and route similarity• E.g. suggest car pooling, or public transportation

– Estimate fuel consumption– Draw WiFi coverage maps• E.g. use for managing WiFi roaming

• Currently working on more

• Please join as participant and contact us for designing new experiences

• On-going data collection contest
