Thank you to those users who have installed V4.0.x of OpenSeizureDetector for testing and provided feedback over the last few months. V4.0.6 is waiting for final approval from Google, then it will be released on Play store over the next day or so. I have also released a new version of the Garmin Watch app to go with it.
Phone App
All new users will receive V4.0 and existing users will be asked to upgrade – please upgrade to this latest version as there are quite a lot of small fixes in it as well as some major changes. The main changes are:
- Introduce a ‘Data Sharing’ facility to upload data that causes alarm or warnings to help us improve the OpenSeizureDetector algorithms. Please make use of this, and use it to report real seizures and false alarms so we can build a better detection system.
- Fixed an issue that meant that SMS alerts did not contain the link to the user’s location on some versions of Android.
- The system checks if it is being ‘optimised’ by the Android system and warns the user to disable battery optimisation if it is (optimisation results in the bluetooth radio shutting down and the watch displaying ERR: -xxx errors).
- Resolved quite a lot of issues that prevented the system shutting down properly sometimes, which gave unpredictable behaviour.
- Corrected a mathematical error that had been there for a long time (a bracket in the wrong place). This has made the system more sensitive, so you are likely to want to increase the value of the “Alarm Ratio Threshold” setting to the new default value of 57.
Watch App
There is also a new version of the Garmin Watch app available here: The new version of the watch app is available here: https://github.com/OpenSeizureDetector/Garmin_SD/releases/tag/v1.2
Please upgrade to the latest release of the watch app. It provides the following additional features:
- It sends the 3D data to the phone for logging – this has been identified as being beneficial for seizure detection by some of the research work using the Data Sharing results.
- Fixed a crash on some devices if you have multiple alarms in rapid succession.
- Provides user feedback of an alarm condition or communications fault by buzzing or beeping from the watch.
As usual, please let me know if you have any issues with this release – I intend to roll this out to all users in about a week, so please let me know as soon as possible if you find an issue with it!
