Flamera and Butterscotch Varifocal wowed the crowds
are prototypes that only Meta Reality Labs testers and people lucky enough to attend events like Siggraph 2023 will be able to test out.
The first prototype – Butterscotch Varifocal – won the show’s Audience Choice award and is a follow-up to a previous Butterscotch prototype Reality Labs developed. Butterscotch's display boasted an incredibly high angular resolution of 56 pixels per degree. This is significantly higher than any other VR headset , and at 60 pixels per degree, the human eye can no longer see the screen door effect on displays .
Butterscotch Varifocal takes these displays and goes one step further. It’s designed to fix VR headsets' focal distance issue – as the screen is always a fixed distance from the wearer’s face. Reality Labs has done this by combining eye-tracking with a display that moves. Depending on where you look the screen will physically move further away or come closer to you, and Meta says this creates a “more natural, realistic, and comfortable experience.
Meta's other prototype – Flamera – was named Best in Show. This is a prototype that’s helping Meta look into new approaches to passthrough for mixed reality. Headsets like the Meta Quest Pro use cameras to record the real world, and then that video feed is fed to your headset display, with adjustments made by the headset’s chipset to correct some perspective distortions. These corrections aren’t perfect, however, and this system will never mimic actually using your eyes to view the world.
Flamera – a portmanteau of flat and camera – uses a unique system of lenses and apertures to create a much closer approximation of what our eyes would naturally see. This complex camera setup is responsible for the bug-eye-like design of the headset. For a more in-depth description, you can check out Meta’s explanation

Risk factors for neck pain in college students: a systematic review and meta-analysis - BMC Public HealthBackground During the COVID-19 epidemic, the prevalence of neck pain among college students has increased due to the shift from offline to online learning and increasing academic and employment pressures. Therefore, this systematic review aimed to identify the personal, occupational, and psychological factors associated with the development of neck pain to promote the development of preventive strategies and early intervention treatment. Methods Seven electronic databases were searched from inception to December 2022 for cross-sectional studies, cohort studies, case-control studies, and randomized controlled trials (RCTs) on neck pain. The quality of the selected studies were assessed by American Agency for Healthcare Research and Quality (AHRQ) or the Newcastle-Ottawa Scale (NOS). Pooled odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were calculated to evaluate the effects of the included risk factors on neck pain. Results Thirty studies were included, including 18,395 participants. And a total of 33 potentially associated risk factors were identified. Ultimately, 11 risk factors were included in the meta-analysis after assessing, and all results were statistically significant (P | 0.05). The factors supported by strong evidence mainly include the improper use of the pillow (OR = 2.20, 95% CI: 1.39 to 3.48), lack of exercise (OR = 1.88, 95% CI: 1.53 to 2.30), improper sitting posture (OR = 1.97, 95% CI: 1.39 to 2.78), history of neck and shoulder trauma (OR = 2.32, 95% CI: 1.79 to 3.01), senior grade (OR = 2.86, 95% CI: 2.07 to 3.95), staying up late (OR = 1.80, 95% CI: 1.35 to 2.41), long-time electronic product usage daily (OR = 1.53, 95% CI: 1.33 to 1.76), long-time to bow head (OR = 2.04, 95% CI: 1.58 to 2.64), and emotional problems (OR = 2.09; 95% CI: 1.66 to 2.63). Risk factors supported by moderate evidence were high stress (OR = 1.61, 95% CI: 1.02 to 2.52) and female gender (OR = 1.69, 95% CI: 1.52 to 1.87). Conclusion This study obtai
