U+1D9E7 "𝧧" Signwriting Movement-Floorplane Arm Circle Hitting Wall Small Single Unicode Character

U+1D9E7 "𝧧" Signwriting Movement-Floorplane Arm Circle Hitting Wall Small Single is a symbol from the SignWriting script, a writing system designed to visually represent sign languages through iconic glyphs that depict hand shapes, movements, and facial expressions. This specific character describes a precise movement in the horizontal floorplane where an arm makes a small, single circular motion that ends with a "hitting a wall" action, suggesting the arm moving forward and then abruptly stopping as if meeting a solid barrier. It is used by sign language writers to encode the nuanced dynamics of a sign, including the size, path, and contact of the movement, contributing to a detailed documentation of signed languages for education and research.
