Flow of Qi: System of Real-Time Multimedia Interactive Application of Calligraphy Controlled by Breathing

摘要

By using novel UWB (ultra-wideband) sensor, we may acquire the breathing signals of human body. After real-time analyzing, parameters such as amplitude, frequency, and slope of breathing waves will be obtained continuously. Combine these parameters with strokes of Chinese calligraphy, for example, amplitude stands for the darkness of stroke and then speed and slope both represent the rhythm of stroke, an interesting multimedia interactive application of visual art which is related to famous Chinese calligraphy is developed and a suitable algorism for real-time interaction of breathing signal is accomplished.
