OpenSeizureDetector

Open Seizure Detector is an epileptic (tonic-clonic) seizure detector / alert system that utilises a smart-watch to detect shaking or abnormal heart rate, and raises an alarm for a carer. If the wearer of the watch shakes for 15-20 seconds, the device will produce a warning. If the shaking continues for another 10 seconds it raises an alarm. It can also be configured to raise alarms based on measured heart rate or O2 saturation.

The phone app communicates with the smart-watch and can raise alarms in one of three ways:
- Local alarm - the phone emits an alarm sound.
- If it is being used in the home, other devices can connect to it via WiFi to receive alarm notifications.
- If it is being used outside it can be configured to send SMS text message notifications that include the location of the user, as wifi notifications are not possible away from home

Please see the Installation Instructions (https://www.openseizuredetector.org.uk/?page_id=1894) for help with setting up this app.

The system includes self-checking to make sure it is functioning correctly, and will beep to warn the user of faults to help provide reassurance that it is working.
Note that the app will give false alarms for some activities that involve repeated movements (brushing teeth, typing etc) so it is important that new users spend some time to get used to what will set it off and use the mute function if necessary to reduce false alarms.

You need a Garmin Smart Watch that is connected to your Android device or a PineTime watch for OpenSeizureDetector to work.. (it also works with a BangleJS Watch if you have one which is connected to your Android device)

The system does not use any external web services to detect seizures or raise alarms, so is not dependent on an internet connection to work, and no subscriptions to commercial services are needed. We do however provide a 'Data Sharing' service to allow users contribute to the development of OpenSeizureDetector by sharing the data collected by their device to help improve the detection algorithms.

I recommend subscribing to email updates to the OpenSeizureDetector web site (https://openseizuredetector.org.uk) or Facebook page (https://www.facebook.com/openseizuredetector) if you use the app so I can contact users if I find an issue you should know about.

Note that this app has not been subjected to clinical trials to confirm its detection reliability, but I have had some positive feedback from users saying that it has detected tonic-clonic seizures reliably. We hope to improve this situation by using data provided by users with our Data Sharing system
See also https://www.openseizuredetector.org.uk/?page_id=1341 for some examples of it detecting seizures.
