Hands-free page turning. 【AI Page Turner】A new PDF viewer which allows you to turn pages using only your face. In other words, hands-free page turning. Using artificial intelligence, AI Page Turner detects your facial gestures to signal page turns. Page Turning has been a centuries-old problem for musicians. Let's fix it together. —————————————————————————— 【Promo Video and Demo】https://youtu.be/eVeNdBt7uq0 【App Website】https://michaelng126.github.io/ai-page-turner/ "I can finally practice uninterrupted. It works like magic!" - Robert, Concert Pianist "Winking to page turn is brilliant - and I love the other actions too." - Anastasia, Flautist —————————————————————————— Full Description: ============================ AI Page Turner ============================ -【AI Page Turner】A new PDF viewer which allows you to turn pages using only your face. In other words, hands-free page turning. This is especially meant for musicians, who need to turn pages of their sheet music but have both hands occupied. It is also for people with machine-related injuries who wish to avoid scrolling. -【Full Customization】With 70+ advanced settings combinations (and ever more in updates), you can customize your experience to fine-grained detail. -【Multiple Face Gestures】Struggling to do one of the face gestures? Just switch it out in the settings! There are many for you to choose from. -【Partial Page Mode】Unique to AI Page Turner, zooming into the page automatically switches to Partial Page Mode. In Partial Page Mode, your face gestures scroll the page down to the next section, instead of jumping to the next page. Perfect for practising from small notes! Or for reading small text. ============================ Your Privacy ============================ -【Privacy】We believe privacy should be simple. Your video stays on your device. That’s it. All face gesture detection is done on device, without uploading to the internet. You could even try turning off your internet connection to see for yourself. You can find the full privacy policy on the app website below. ============================ AI Page Turner Pro ============================ -【AI Page Turner Pro】Pro gives you access to all features, including - Access to all page turning actions, including winking, mouth opening, kissing, and more! - Access to all 70+ advanced settings combinations. - Supporting the development of future features. ============================ Even More ============================ -【Onboarding】You will be onboarded on first open, seeing the wink indicator which tells you whether you are winking or not. After this, you can open your own PDF files and turn pages as shown. -【Immersive Mode】Tapping the screen hides all distractions (e.g. the info bar), allowing uninterrupted focus. -【Two Page Mode】Available in the settings, two page mode allows you to view PDFs two pages at a time. Perfect for duets with parts on each page. -【Partial Page Mode Fine Calibration】Want to scroll down only half a page (so that you don't cut off that stave?). Available in the settings, you can adjust the page down fraction accordingly. -【and more...】and there's more to discover. Let's fix page turning together! Happy Page Turning!
