Release of Version 5 of OpenSeizureDetector

We are pleased to (finally!) release the new Version 5 of the OpenSeizureDetector Android App – it should be on Google Play Store shortly.

There are several major changes in this version:

  • The ability to download Machine Learning (“AI”) models that we are making with the data provided by users via our ‘Data Sharing’ programme.
  • A first-use setup “Wizard” to guide new users through setting up the system for the first time (using either a PineTime or Garmin watch)
  • A simpler user interface – it defaults to a “Basic Mode” with no graphs, just a simple OK/ALARM status and Raise/Mute alarms buttons. You can disable Basic Mode in the General Settings page to get something that looks more like the current version.
  • A lot of ‘behind the scenes’ improvements to improve the stability of the system and make it easier to maintain in the future.

You can see the complete CHANGE LOG in the Source Code repository.

To simplify the user interface, it only lists PineTime, Garmin, Network and Phone data sources by default. If you want to select one of the more ‘experimental’ data sources, there is a ‘Developer Mode’ that can be enabled in the settings.

The Machine Learning model that the system recommends during installation is the ‘Run24’ one that I made in January and have been testing since. I am very pleased with its performance for or son, with it having >90% detection reliability. When I analyse the recently provided data from users, I am seeing just over 80% reliability, so it is comparable to the existing algorithm with ‘flap’ detection – but it should give fewer false alarms. Note though that it does still false alarm for doing things like using hand tools and travelling in a vehicle. Once the release of this version of the Android App has settled down, I will get back to working on a better model and making that available to users.

Thank you to everyone who has taken part in the beta testing of this app – you have found issues and made some very helpful suggestions to improve it.

When you find issues with this version, please report them via our bug tracker, or email graham@openseizuredetector.org.uk.

If you find a serious issue and need to go back to the previous version, you can download the installation (.apk) file for an earlier version from our source code repository: https://github.com/OpenSeizureDetector/Android_Pebble_SD/tree/master/releases

Thanks!

Ooops! V5.0.7 Broken

Apologies to the beta testers, but the ‘final’ test version that I published last night (V5.0.7) is partially broken – The Basic Mode user interface works, but the Advanced Mode crashes because of an issue with the graph drawing library.

I would suggest not upgrading if you haven’t done so yet.

If you see the issue, you get a crash when in advanced mode. To get it working again:

  • Do a ‘Force Stop’ (or re-boot the phone) to make sure OpenSeizureDetector is properly shutdown.
  • Start OpenSeizureDetector
  • As soon as the start-up screen appears, press the ‘Edit Settings’ button to bring up the settings screen.
  • Go to General -> Basic Mode and enable the Basic Mode checkbox.
  • Then when you exit the settings screen, the system will re-start into Basic Mode and should work correctly.

I’ll look into what caused this and issue a new ‘final’ test version later this evening.

Sorry for the inconvenience!

Web Site Update

I have updated the web site at https://openseizuredetector.org.uk to try to make it simpler for new users to find information. There are is a new home page that links to installation instructions, a user guide page for existing users and a developers page. I’m afraid the developers section is still very sparse – detail to follow.

The old web site pages are still there, so if you see something that is missing, please let me know and I’ll move it across.

Please contact graham@openseizuredetector.org.uk with any comments or suggestions.

Thanks

PineTime Watches Back in Stock

For those who have been waiting for Pine64 to get the PineTime watches back in stock, they have them available now on their global store (https://pine64.com/product/pinetime-smartwatch-sealed/).

I have just ordered a few so I know I have the same watch as any new users who are trying to set it up.

Update: I ordered the watches on 02 June and they arrived on 20 June, so delivery to the UK is about 3 weeks.

The setup instructions (with some video demonstrations are here: https://openseizuredetector.github.io/pages-user/pine-time-installation.html)
