Complete eye tracker info table in webapp

[isolver]

Some data about the eye tracker is being provided to the web app, but it is not complete. Need to:

• [x] Fix fields that are currently static and not changed to appropriate values. For example tracker model name.
• [x] Gaze information is an average of both eyes when binocular data is available (and valid). Need to add some info about each eye as well:
  • each eye position
  • each eye pupil size

For both average and individual eye data, add:

• [x] Noise level calculation. (Need to agree on what measure is best for this, stdev, RMS, other??)
• [x] % of samples collected over the last second that contained missing data. If % of invalid samples goes above a threshold % (settable in config), change the color of the table cell background. Perhaps have 2 thresholds, each using a different color for background.
• [x] % of samples from last second where the gaze position is outside the 'acceptable gaze value range'. This can be defined by a multiplier in the config file. For example setting it to 1.1 would make the valid tracking range be 110% of what the gaze coord range for the screen itself would be. Also, perhaps have 2 thresholds used to control the 'warning' or 'error' color used for the appropriate table cell backgrounds.

love the ideas. Re noise level, would this be a within-fixation measure?

[isolver]

for noise, was thinking of just using a moving window and calculating RMS or stdev for it.

When parser is done, if it is available online (I want it to be), then we could only use periods of 'fixation' for the calc I guess.

Sounds good. Something is better than nothing to begin with.

The checked items are now done as a first pass for input; no thresholding to cause 'alert' and 'warning' color changes yet .

I'm not sure, given the intended app usage, what level of detail in terms of eye data should be displayed. Take a look when you can. I'm wondering if less is more in this case, and therefore if some of the current info should be removed.
