U+1D9D4 "𝧔" Signwriting Rotation-Floorplane Alternating Hitting Floor Unicode Character
Unicode Version 17.0
𝧔
U+1D9D4 "𝧔" Signwriting Rotation-Floorplane Alternating Hitting Floor is a symbol from the SignWriting script, a writing system designed to visually represent the physical movements and gestures of sign languages. Specifically, this character denotes a rotational motion occurring in the floorplane, which is the horizontal surface area at the signer's waist level or lower, and it indicates an alternating hitting action where a hand or body part moves in a back and forth or striking pattern against that plane. This glyph serves as a precise notation for transcribing the nuanced dynamics of signed communication, allowing for detailed documentation of movement direction, contact, and rhythm in sign language orthography.
