U+1D94D "𝥍" Signwriting Travel-Wallplane Rotation-Wallplane Alternating is a symbol within the SignWriting script, which is a writing system specifically designed to visually represent the movements, handshapes, and facial expressions of sign languages. This particular character denotes a complex motion in which a hand or other articulator travels along the wallplane, which is the vertical plane facing the signer, while simultaneously rotating in an alternating manner between the two horizontal directions of that plane. It is used in the precise notation of sign language to capture the nuanced choreography of signs that involve both linear movement and twisting orientation.
