3 Dimensional Visualization of Manual Movement and Nodding in Sign Language
Yuji Nagashima, Hideyuki SUMIDA · Journal of the Visualization Society of Japan · 2003
Sign language is one of the communication means for the hearing disabled. It is a visual language and the articulatory components of a sign are presented in three-dimensional space. Sign language complicates analysis from complexity of articulators. An acquisition of image and three dimension data is necessary for detailed analysis of sign language.In this report, we have been constructing synchronous input and analysis system for video image and motion-captured data such as location and orientation of the hands and head in relation of the magnetic source. Simultaneously, we have been measuring hands configuration by gloved type sensors. Then, we have been drawing a graph in time axis for visualization of nod and three-dimensions hand movement of native signer and provided further insights synchronous analysis way by a trial manufacture system.
