Related to the complexity of the task, there is no doubt that various cognitive processes related to visual search, navigation, covert attention, working memory, etc., were ongoing throughout the task that lasted several minutes. Because, we did not control these factors in the experimental design, as it was designed to be a free and active task, we had no way to account for such factors as covariates in the analysis – a situation that is pervasive in real-world cognitive pupillometry. The perspective of our correlation analysis was to essentially treat these cognitive processes as “noise” in the pupillary signal that would influence pupil size independently (and likely to a lesser extent) with respect to luminance information. We do not believe that cognitive effects could explain the robust negative association we found between pixel luminance and pupil size in this task, nor can they explain the reported blue sky effect in the correlation maps. If anything, the correlations we measured are likely an underestimate of the actual strength of the influence of luminance on pupil size because of the unaccounted for “noise” introduced by continuous cognitive processes. Sky today announced the launch of Sky Glass, dramatically simplifying the way customers watch TV by integrating hardware, software and content. Sky Glass will be the only TV with award-winning Sky inside.

Green and blue showed a similar pattern of results in the correlation maps, in part, because they were strongly correlated over time, specifically for pixels located in the sky region. In an attempt to isolate the influence of green vs. blue, we performed a follow-on analysis that converted the images from 8-bit RGB image space to CIELAB space, which is an alternative representation of an image in a three dimensional space that is more aligned with human perception. The three channels of CIELAB space include L* which is a representation of luminance on a scale of 0 (lowest luminance) to 100 (highest luminance), a* which is a representation of red-green chromaticity on a scale of −100 (more red) to 100 (more green), and b* which is a representation of blue-yellow chromaticity on a scale of −100 (more blue) to 100 (more yellow). We computed correlation maps using the same procedure as before, except in this case, we used pixel values represented in the three channels of L*a*b* space. Post hoc data analysis involved generating the sequence of full-screen “snapshots” to replay the sequence of visual stimulation on the screen as subjects freely explored the virtual environment ( Figure 1B). We generated the snapshot associated with every 10th frame for an effective temporal resolution of 12Hz (screen refresh rate was 120Hz), exporting the images in.png format. To save disk space, the sequence of images was then compressed in Matlab using the built-in MPEG video encoder, reducing the file size footprint by about 100x from ~100gb for all.png images to a video of ~1gb per subject. To ensure that video encoding did not introduce significant artifacts to the image data, we compared RGB pixel values of the original.png images to the compressed video frames and found that over 99% of pixel intensity differences were within a range of +12, a criterion that corresponds to 5% of the entire 8-bit color spectrum (0–255).If you’re looking for a new TV now, however, and the idea of dishless Sky TV appeals, then Sky Glass is an attractive option. Despite these positives, TNE currently remains significantly underused. With only 26 685 procedures performed in 2019 (comprising less than 3% of all OGDs the UK 2), TNE has considerable potential to scale up and meet the demand of the post-COVID-19 landscape. Indeed, the COVID-19 pandemic may provide the stimulus for redefining the way services are conceived and delivered in novel and interesting ways, such as one-stop outpatient TNE services for upper GI symptoms 11 or community diagnostic hubs coupled with radiology. You can access close to 30 apps on the TV, including popular ones such as All4, BBC iPlayer, ITVX, Apple TV+, YouTube and Prime Video. You don't need a Sky Glass TV to get Sky content. You can also get it through a Sky Q box or Sky Stream. In addition to the finding that blue light enhances the PLR, we found that this effect was specific to occurring above fixation. This result was highly consistent across subjects as observed in the individual correlation maps for the green and blue channels ( Figure 3, right). While location of fixation was not experimentally manipulated or controlled in this analysis, these results indicate that fixations toward the horizon may have comprised the majority of fixations. When this well-matched visual pattern of blue on top and terrain on bottom fell onto the retina, it induced robust pupillary responses that accounted for a large degree of variance in the pupil signal by comparison to other areas or features of the environment. One surprising aspect to this finding is that the blue sky itself had lower luminance intensity compared to the terrain below, which was composed of more red and green hues that tend to carry stronger luminance signals (See Supplementary File 1). So while the strength of the luminance signal tended to be stronger below fixation, it was the specific temporal pattern of blue luminance above fixation that correlated most with pupil size, indicating the strength of this contextual effect. Confirming the “Blue Sky Effect”

Because the task was performed in a virtual environment of our design, which can be described as a mountainous desert wasteland landscape, the set of images seen by subjects on the computer screen tended to have a particular spatial structure and spectral composition. The pattern of results we observed in Experiment 1 are clearly influenced by this structure. For example, the correlation maps show correlation values that vary primarily in the vertical direction, but not the horizontal direction, likely due to the structure of the images themselves. In a horizontal slice of the image near the bottom there will tend to be more red, brown, and grayish colors associated with the terrain and less variability from left to right. A horizontal slice in the upper part of many images would often consist predominantly of blue color associated with the sky, as long as subjects are looking toward the horizon (which was likely a common focal point for subjects as they navigated the virtual environment). If the experiment were run in a different virtual environment or even a real-world environment, it is likely that the structure of the correlation maps would change to reflect the prevailing spatial and spectral structure of those images. While this does not greatly impact the main finding in this paper that supported the contextual effect of the blue sky on pupil size, we would expect differences in the structure of correlation maps depending on properties of the visual environment if future studies use this same approach. For controlled studies in cognitive pupillometry, this also suggests a prime importance for controlling the level (and visual patterns) associated with blue light in particular. Experimenters should be careful to counterbalance conditions if color stimuli are used with variation along the color spectrum to avoid confounds that might influence interpretation of phasic pupillary responses to cognitive events. Such color spectrum effects should also be accounted for (or anticipated in the analysis) in these studies as equating luminance alone may not have the desired effect of equating the strength of the pupillary light response to differently colored stimuli. As shown here, the pupil response to a blue stimulus is significantly larger than to a red stimulus with well-matched luminance. As our data show, even the relative location of the blue stimulus (above or below fixation) can impact the strength of the pupil response. Further care should be taken in interpreting pupillary data, especially when examining pupillary responses to naturalistic or more complex stimuli that match the spatial structure of the blue light from above effect (e.g., blue predominantly in the upper part of the image).

We hypothesized a foveal bias in the correlation maps, consistent with research showing that stimuli nearer to fovea induce stronger PLRs than stimuli in the periphery ( Crawford and Parsons, 1936; Legras et al., 2018; Hu et al., 2020). This prediction is also related to the structure of the human visual system as the distribution of photoreceptors changes dramatically as a function of distance from the fovea, and there are significant differences in visual function between foveal, parafoveal, and the peripheral regions ( Preuschoff et al., 2011; Strasburger et al., 2011). Previous research has shown that cone mediated pupil responses to photopic light (i.e., simple circular patches of light stimulus) are maximal up to 7 degrees of visual angle, and has reasoned that the decrease in response may be due to the drop off in cone density after 7 degrees ( Legras et al., 2018; Kelbsch et al., 2019). Our data, however, did not support this hypothesis, instead revealing a robust and unpredicted pattern in the correlation maps. Pixels very close to gaze position actually tended to correlate the least strongly with pupil size. This pattern was most prominent for the red channel, in which all of the pixels within about 2–3 degrees from fixation were not significantly associated with pupil size, but it was also apparent in the blue and green channels.
