sensemycity overview
DESCRIPTION
This is an overview of what our crowdsensing platform is and can achieve, including examples from a beta data collection and examples of single case and longitudinal stress study. The latter were carried out in cooperation with Prof. João Paulo Cunha, Prof. Mariana Kaiseler, Prof. Cristina Queirós.TRANSCRIPT

What is a crowdsensor?
• Leveraging the power of the crowd • Use people as moving sensors to gather data
• Smartphones are a ubiquitous plaIorm with many connecKvity possibiliKes – 22% of the world populaKon 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 plaIorm – ApplicaKon for Android OS – Cloud storage – VisualisaKon plaIorm
CrowdSensor
SenseMyCity App
• Internal Sensors – LocaKon: GPS, Network – MoKon: accelerometer,
gyroscope, magnetometer – ConnecKvity: WiFi, cellular – Environmental: temperature,
pressure, humidity
• External Sensors – On-‐Board DiagnosKcs (OBD) – Vital Jacket (ECG) – Zephyr (heart rate)
Back and Frontoffice
• Storage and visualisaKon backoffices
• Data collecKon and storage following data protecKon guidelines – Informed consent – Privacy – Data ownership
Mobility Study
• 30 day data collecKon campaign • 10 users • ≈ 40h of data • ≈ 142k GPS-‐indexed points
Average Speed
Aggregate Fuel ConsumpKon
Important Places
# WiFi APs
Stress Assessment
• Example study case with single driver – hgp://youtu.be/RLQL5ptIQiE
• Example longitudinal study with quesKonnaires and recall phase – hgp://youtu.be/YygyIUXskdY
An example longitudinal study
CrowdSensor
Typical Use Cases • Urban data collecKon • Longitudinal studies on specific groups – Police officers, bus drivers, firemen, …
• Algorithm validaKon – Machine learning – Context inference
• Service acceptance, user trials
What you can do with it?
• Configure the plaIorm for your own crowdsensing applicaKon – You can choose only a subset of sensors and add your own interface
– You can add a workflow – You can add geo-‐located quesKonnaires – You can record voice answers
