Terminating a GazePoint Calibration via Mouse Click Causes a crash in the Core

[dtg3]

If you are using the GazePoint Control Application begin a calibration, but cancel it by clicking the mouse the Core will hang and crash.

[dtg3]

There isn't a clean way to prevent this as the GazePoint sends ZERO data informing us that calibration has stopped so the Core simply continues to wait like a good program. One option might be to have a timeout on calibration between receiving data points.

[dtg3]

Could consider using:
Reader.BaseStream.ReadTimeout = 5000;

This would set the timeout to 5 seconds. It can be restored to the default value with:
Reader.BaseStream.ReadTimeout = System.Threading.Timeout.Infinite;

One important detail to keep in mind is that the CALIBRATE_TIMEOUT (duration of the calibration point) and the CALIBRATE_DELAY (animation time) settings for Gazepoint API can be changed. Therefore the timeout would need to consider those values and not use an arbitrary timeout value.

Noted the issue in the documentation in the event that a reliable solution is not present for release.

It can be one of the known issues in the release notes.

[dtg3]

Okay. For this release (0.1.0) we will leave it as a known documented issue. I'll keep this open so we fix it in future releases.

@dtg3 @Joshua2000B was this fixed or looked at? It could still be a known documented issue if we don't want to fix it in this release.
