To confirm this finding and evaluate whether the “blue sky effect” has a more generalized effect on the PLR, we ran a second experiment with a controlled task to assess whether the PLR is indeed stronger, specifically, when blue is seen above fixation. The experimental procedure was careful to match the luminance level across color stimuli (gray, blue, red, and green). The only variables that were manipulated on each trial were the color presented (paired with gray) and its location (on top, bottom, left, or right). Results showed that the PLR was indeed stronger for blue stimuli in comparison to green and red, which replicates results from prior studies ( Suzuki et al., 2019). Importantly, the results also showed a specific effect in which the PLR was strongest when blue was presented on top compared to on bottom. There were no other statistically significant effects associated with the relative location of other color stimuli. This result provides additional support to the blue sky hypothesis, suggesting that the PLR is influenced most strongly by blue light, and in particular, when blue light is present above fixation. I eventually managed to connect it to my home Wi-Fi using the TV’s WPS button and the same on my Devolo Magic Powerline adapter. If you come across the same issue, you’ll have to (rather counterintuitively) select the “I have Sky Broadband” option, as the “third-party broadband” connection option doesn’t give you the choice of using WPS. You don't get access to full range of Sky channels on the Now app, and you won't get Freeview channels either, but since your TV gets Freeview channels that isn't such a big deal.

In this study, we examined correlations between pupil size and dynamic image statistics in the context of a free visual search and navigation task in a 3D virtual environment. We found that blue and green pixel intensities had a disproportionately large impact on pupil size in comparison with the red color channel. Furthermore, we found that visual scenes in which blue was predominantly overhead had the strongest influence on pupil size, which led us to hypothesize a “blue sky effect.” We conducted a follow-up controlled laboratory experiment and found evidence consistent with our hypothesis, showing a specific sensitivity of the PLR to blue light when it is located above fixation. From an ecological perspective, we speculate that the heightened sensitivity of the pupillary system to this visual pattern may be a useful adaptive response due to the persistent association between sunlight, large increases in brightness, and the blue sky in our daily lives. From a practical standpoint in terms of pupillometry research, the findings of this report suggest that equating luminance alone may be insufficient to account for luminance effects on pupil size if multi-colored stimuli and/or naturalistic images are used in psychological research. More research is necessary to fully understand how best to account for the influence of light on pupil size for studies or applications in complex visual environments outside the laboratory. Data Availability Statement 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). To further probe this interaction effect, we conducted one-sample t-tests on the PLRmin difference scores for each color channel and orientation type (vertical or horizontal; Figure 7, bottom). Blue-top – blue-bottom was the only comparison that was significantly different from zero [ t(14)=−3.60, p=0.003, FDR<0.05] indicating that the PLR was significantly greater specifically when blue was located on top compared to when blue was located on bottom. All other comparisons (red/top-red/bottom, red/left-red/right, green/top-green/bottom, green/left-green/right, and blue/left-blue/right) were non-significant (all values of p>0.05, FDR>0.05). This effect could not be explained by baseline differences in pupil size prior to the stimulus, as the 500ms mean pre-stimulus baseline pupil size for blue-top was 913a.u. ( SD=256a.u.) and for blue-bottom was 926a.u. ( SD=282a.u.), and the t-test indicated a non-significant difference in baseline pupil size, t(14)=0.53, p=0.6. In fact, there was a non-significant difference in baseline pupil size for all comparison pairs ( p>0.05), ensuring that differences in baseline pupil size could not explain this pattern of results. This highly specific effect for blue was consistent with our hypotheses that the response of the pupil to blue light would be greater than red and green, and also that blue on top would induce a significantly larger PLR than blue on bottom. The specificity of this result is consistent with the hypothesized blue sky effect and provides a potential explanation for the significant contextual effect in Experiment 1, in which blue pixels above fixation had the strongest modulatory effect on pupil size. Discussion And it remains the case that not all programmes are available to playlist in the same way they can be recorded on Sky Q. Match of the Day on a Saturday night, for example, won’t appear on your Playlist until the following Monday due to rights restrictions. However, Playlist has improved since launch and you can now add more programmes than ever, including BT Sport shows.As units confront the challenges of COVID-19, the versatility of TNE provides a route to recovery, with potential to enhance existing services and increase productivity. Before Sky Glass there was the Now TV app. It's just called Now... now, but the functionality is the same, it gives you access to Sky programmes, movies and sports for a monthly fee. It's effectively a Sky streaming service. DEVCOM Army Research Laboratory, Human Research and Engineering Directorate, US Army Research Laboratory, Aberdeen Proving Ground, MD, United States

Transnasal endoscopy (TNE) uses an ultra-thin endoscope to visualise the upper gastrointestinal tract and is a safe, well-tolerated and resource-efficient alternative to conventional transoral endoscopy that is currently underused. Sky Glass is a big product for the UK satellite TV giant. Not only is it the first TV the company has built, it’s also the first time Sky has produced a streaming-only product without compromising streaming quality and features.

Reduce financial crimes compliance risk with LexisNexis® Financial Crime Digital Intelligence Learn More In classic cognitive pupillometry studies, it has been critical to equate luminance across stimuli and/or experimental conditions to isolate cognitive influences on pupil size and ensure that results are not driven by confounds due to variable luminance. While this careful control of luminance has led to a great deal of knowledge about the relationship between pupil size and cognition ( Aston-Jones and Cohen, 2005; Sirois and Brisson, 2014; Mathôt, 2018; Hoffing et al., 2020; Joshi and Gold, 2020), it also limits the ability to generalize research findings to contexts in which luminance cannot be controlled. For example, it would be unfeasible to control for luminance in real-world tasks and would impede the study of naturalistic gaze behavior in experiments using complex stimuli, to replicate the spatial variation in local contrast and luminance that occurs in the natural world ( Frazor and Geisler, 2006). One of the best things about traditional Sky boxes is the ability to record TV onto the hard drive built into them. First time on forum, and tought I would share my experience of upgrading the HDD on my Sky HD box (blue screen experience below). This is an updated version of our original Sky Glass review, in which we awarded the TV three stars. After a series of updates to the television’s user interface and picture quality, we’ve upped the star rating and added a well-deserved Recommended award.

Of the 225 procedures (comprising 98 from the pilot and 127 from the full roll-out), there were 209 completed TNE procedures (defined as successful nasal and oesophageal intubation with subsequent examination of the upper GI tract to achieve the clinical intent without needing to abort the procedure due to patient factors), giving an unadjusted TNE completion rate of 92.9%. This included three patients in whom initial discomfort with TNE was remedied with the adjunctive use of nitrous oxide and oxygen mixture (ENTONOX) to successfully complete the transnasal procedure and six patients in whom ENTONOX was used pre-emptively to achieve the same result.The observed blue light from above effect on pupil size has practical implications for analysis of pupillary data in complex virtual environments and in real-world scenarios. For future, real-world systems that aim to measure environmental light to account for the influence of non-cognitive luminance effects on pupil size, it may be pertinent to ensure that blue light is captured and modeled appropriately relative to other wavelengths to ensure the best prediction of light-induced pupillary fluctuations. It could also be the case that a sensor specifically tuned to blue wavelength light may be sufficient for some applications. There is, however, still much work to fully understand the efficacy of subtractive models that attempt to better characterize cognitive influences on the pupil by subtracting or factoring out estimates of non-cognitive influences. We believe that a major contribution of this work is in rejecting the foveal bias hypothesis for estimating the influence of luminance on pupil size in complex visual environments. It does not appear to be the case that the visual system uses an area around the high density fovea as a sensor to pool luminance information for driving the PLR. The system instead seems more sensitive to global patterns of information and contextual cues, like the blue sky effect and perhaps others, in determining the appropriate pupil response to light in a given environment.
