EMR pen-enabled e-readers and notebooks

EMR (pen support)

— the ability to work with passive EMR styluses without batteries. Such a screen independently recognizes the pressure and tilt, offers "hover" cursor functionality, and reliably rejects palm touches. The experience is closer to writing on paper and more stable than capacitive styluses. Compared to active standards like AES/USI, it doesn't require charging or pairing and has lower latency. In practice, this means convenient handwritten notes, precise annotations in PDF/ePUB, sketching, and editing diagrams; compatibility with a wide range of EMR pens (Wacom-class, including many S Pens) facilitates replacement and upgrades.
