A sliding-recognition-voice integrated system for braille recognition and its related verification. (IMAGE)
Caption
Multi‐channel capacitive signals recorded during sliding over the Braille phrase “Hi! SCU” using the G‐HL‐SIL array sensor (a) and Without‐SIL array (b). (c) Mis‐trigger reduction factor: the ratio of mis‐trigger counts between Without‐SIL and G‐HL‐SIL under threshold screening conditions of 1 to 10. (d) Confusion matrix of 26 static Braille letters (A–Z) classified by a CNN model (accuracy: 100%). (e) Multi‐channel capacitive signals acquired at different sliding speeds during Braille recognition. (f) Confusion matrix of five representative letters (H, I, S, C, U) at different sliding speeds. (g) Workflow of the integrated slide‐recognition‐vocalization system, including sliding input, multi‐channel signal acquisition, data processing, and vocal output.
