E-Prime Extensions for Tobii Pro 3.2
Tobii Pro Lab-enabled experiments support having the same AOI name across multiple Slides. For example, an experiment may have 2 Slide objects: Slide1 and Slide2. Also, both of those Slides have SlideText sub-objects. Users can specify AOIs over the SlideText sub-objects and have the same AOI name for both.
Having the same AOIs across multiple Slides is useful for Tobii Pro Lab analysis. Users can view the gaze duration on the AOI across both Slides. Grouped tags can be set for the two AOIs by using the TPLSetTag PackageCall in E-Prime. This produces a cumulative gaze calculation over the two AOIs in Tobii Pro Lab's Metrics output.
