PROBLEM TO BE SOLVED: To provide a biological signal analyzer by which a lot of information can be acquired without being lost because the analysis of biological signal is carried out at a high dimension, while even a person having no mathematical knowledge can instantaneously confirm the state of biological signal because the analysis result of biological signal is displayed in three-dimensional space coordinates.SOLUTION: The biological signal analyzer includes: a biological signal receiver 100 to receive a biological signal a high dimension space analyzer 110 to analyze the biological signal in m-dimension (m is an integer not lower than 4) and a three-dimension display signal transmitter 140 to transmit a three-dimension display signal that is a signal produced based on the analysis of the high dimension space analyzer 110 and performs display in the three-dimension space.COPYRIGHT: (C)2011,JPO&INPIT【課題】生体信号の解析を高次元で行うため、多くの情報が失われること無く取得できる一方、3次元空間座標に生体信号の解析結果を表示するので、数学的に知識のない者でも瞬時に生体信号の状態を確認することができる。【解決手段】生体信号を受信する生体信号受信部100と、前記生体信号をm次元(mは4以上の整数)において解析する高次元空間解析部110と、前記高次元空間解析部110の解析に基づいて生成される、3次元の空間に表示させるための信号である3次元表示信号を送信する、3次元表示信号送信部140を備える、生体信号解析装置を設ける。【選択図】図2
