“Design[ing] a set of characters for a new phonetic alphabet or syllabary for a specific context.” Our table developed a ‘Clap-abet’, in which letters are hand signals which include a sound, such as ‘clap’, ‘snap’ (click), ‘tap’. We drew out an accompanying notation with diagrams for learning purposes, but it can also be taught easily person-to-person without diagrams. It has some semblance to children’s clapping games.
This alphabet can be used in the absence of other senses: it can be listened to, it can be watched without audio, it can be written out hand-to-hand to another person. There is scope to vary rhythm and loudness for emphasis, spacing of ideas, and questioning.
