SPATIAL WRITING RECOGNITION METHOD, DEVICE AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a spatial writing recognition device, recognizing the spatial writing without stopping before and after the writing operation to improve the recognition rate of spatial writing. SOLUTION: This spatial writing recognition device is loaded with a spatial writing recognition module 1020. The module includes: an inertia sensor module 1022 for measuring the acceleration of the operation in a space; a storage module 1028 for storing predetermined arithmetic information and parameter for tracing the moving locus of spatial writing and pattern information on the moving locus; an arithmetic module 1024 for calculating the movement speed from the acceleration using the arithmetic information and the parameter, and limiting the positional relationship between predetermined positions constituting the moving locus to correct the calculated movement speed and trace the moving locus adopting the corrected movement speed; and a recognition module 1026 for recognizing the spatial writing by comparing the traced moving locus with the pattern information.
