Hello everyone,
I have a question regarding EyeLink 1000 Data Viewer. I created my experiment in PsychoPy, but I believe there may be an issue with the ROI (Area of Interest) setup.
Briefly, my experiment contains 25 item descriptions that participants read. To randomize the order, I used a loop with a CSV file. The experiment runs smoothly: the texts are presented in different orders across participants, and key responses work as expected. In debug mode, I can clearly see that the ROIs are being created and displayed correctly.
However, when I open the data in EyeLink Data Viewer, I encounter two problems:
-
The Area of Interest panel shows “empty area of interest”
-
Most importantly, I cannot see the text stimuli at all in the Data Viewer (I only see a blank page)
Because of this, I am unable to inspect fixations or reading behavior for the full set of 25 texts.
I am currently working on my thesis, so I would be extremely grateful for any advice or suggestions on what might be causing this issue or what I should check (e.g., ROI messages, trial structure, or display settings).
Thank you very much in advance for your help.
Hello @Michaela_Mrazova
this is more sr-research question than a PsychoPy-question. From the manual:
5.1.1.5 Interest Area Templates
An interest area template is an .IAS file that contains a set of interest areas. If the same
interest areas are used for several trials, rather than creating interest areas individually for
each trial, users may load an interest area template and apply this template to multiple trials.
The property panel lists the following summary statistics for an interest area template. Fields
that are editable in the viewer are marked with an asterisk (*).
Field - Contents
Name * - Label of the custom interest area set.
IA Count - Total number of interest areas defined in the trial.
IsCustom - Whether the current set of interest areas is user-defined (true) or an interest area template
(false).
Image Name Mapping - If the “Auto Select IAS for Trial” property in the “Output/Analysis” preference settings is true, the value in this field will be used to associate the IAS to trials automatically. This
functionality is obsolete – users are suggested to make use of the trial grouping feature instead
(see Section 7.1.3).
Please note that if an interest area template is deleted from a viewing session, interest areas for
all those trials that use that template will be removed as well.
Best wishes Jens
