I am working on a re-write of the OpenSeizureDetector alarm system. Most of the changes are not visible to the user – they are making it possible to use different detector hardware like the Embrace watch when it is available, but some will affect the user interface, so I’d appreciate any feedback before I do the update….
One change I am thinking of is to include some indicators to show how far the system is off alarming (at the moment I look at the graph on the display, but that is not easy to interpret). The indicators are two horizontal bars which extend as either of the two seizure detection parameters increases – when both get to 100% (filling the screen), the system alarms – they change colour to show how close to the alarm level they are:
- blue = ok,
- yellow = close to alarm level,
- red = exceeded alarm level)
(See the Seizure Detection Algorithm page for more details of how it works).
I wondered what users think of the idea – is it an improvement? Would there be a better way of showing it (I am wondering about two semi circular lines that meet when the system is in an alarm state?), are the lines a bit too thin and dainty? Does anyone look at the graph or should we scrap it and go for a much simpler user interface?



Thoughts? The source code for this version is in the new project github repository under the “v2.0” branch (https://github.com/OpenSeizureDetector/Android_Pebble_SD).
