Supporting smarter, healthier, safer Hajj journeys.
Smart Hajj is designed as an HBC-enabled gateway to help care teams watch over pilgrims' wellbeing, notice potential concerns earlier, and provide timely, compassionate support when it may be needed.
A rising trend can prompt an earlier comfort, hydration, or heat-exposure check.
Health signals
Each signal offers a different view of a pilgrim's wellbeing during physically demanding Hajj conditions.
Tracks temperature trends that may reflect heat exposure or illness-related change.
Heat, sun exposure, and long walking periods can place extra strain on the body. A rising trend can prompt an earlier wellbeing check.
Shows how the body responds to exertion and how effectively it recovers.
Crowds, distance, heat, and fatigue can raise exertion. Sustained unexpected changes can support an earlier rest or hydration check.
Displays the heart's electrical waveform as an additional signal for review.
Intense activity and heat can stress the body. Waveform changes can provide trained teams with another reason to check on someone sooner.
Helps teams notice meaningful changes in activity, orientation, and posture.
Reduced movement or an unusual posture change may indicate fatigue or difficulty and can support a timely check-in.
How the system works
Smart Hajj carries pilot telemetry from wearable nodes through a mobile gateway to participant files and research monitoring tools.
A chest TX node captures ECG and heart rate while a wrist RX node captures temperature and movement data.
Why Smart Hajj
Adaptive sensing explores how lightweight wearables can support longer operation and earlier wellbeing checks in demanding Hajj conditions.
The current protocol supports 5–40 second capture windows and Tx, Rx, or paired System Modes, so teams can collect only the signals needed for each session.
Available in the current session protocolSmart Hajj is a research prototype. HBC, deep-sleep, and 24+ hour operation remain field-development targets and require hardware validation.
Human Body Communication
Human Body Communication, or HBC, uses the body as a short-range communication path between wearable nodes. In Smart Hajj, this research direction lets a chest transmitter explore forwarding ECG and heart-rate data toward a wrist receiver before the phone gateway uploads a complete session.
Instead of treating every wearable as an always-on radio, HBC explores a body-coupled path between the chest TX node and wrist RX node.
TX ChestECG + heart rate
RX WristTemperature + movement
FAQ
Smart Hajj connects compatible wearable sensor nodes to a mobile gateway so authorized research teams can review temperature, heart-rate, ECG, and movement sessions, organize pseudonymous participant data, and explore prototype activity or risk indicators that may support earlier wellbeing checks. It is a research prototype, not a medical device, and must not be used for diagnosis, emergency triage, or as the sole basis for medical decisions.
