Method for measuring microfluctuation of accommodation

Abstract

A method for measuring microfluctuation of accommodation includes attaching at least one first sensing element to the area around an eye of a testee for measuring an electromyograph (EMG) signal, using a processing module to pick up a specified frequency range of the EMG signal as a measurement index of microfluctuation of accommodation, storing the processed measurement index of microfluctuation of accommodation in a storage module, and analyzing the measurement index to evaluate the physiological states of the testee.

What is claimed is: 
     
         1 . A method for measuring microfluctuation of accommodation, comprising steps:
 attaching at least one first sensing element to area around an eye of a testee for measuring an electromyograph (EMG) signal; and   using a processing module to pick up a specified frequency range of said EMG signal as a measurement index of microfluctuation of accommodation, wherein said specified frequency range is 0.1-100 Hz.   
     
     
         2 . The method for measuring microfluctuation of accommodation according to  claim 1 , wherein said EMG signal of said testee is measured in an open field of view. 
     
     
         3 . The method for measuring microfluctuation of accommodation according to  claim 1  further comprising a step:
 storing said measurement index. 
 
     
     
         4 . The method for measuring microfluctuation of accommodation according to  claim 1  further comprising a step:
 evaluating physiological states of said testee according to said measurement index. 
 
     
     
         5 . The method for measuring microfluctuation of accommodation according to  claim 1  further comprising steps:
 arranging a second sensing element near said testee's head for measuring an electroencephalograph (EEG) signal; and 
 evaluating physiological states of said testee according to said measurement index and said EEG signal. 
 
     
     
         6 . The method for measuring microfluctuation of accommodation according to  claim 1 , wherein said specified frequency range is 0.5-50 Hz. 
     
     
         7 . The method for measuring microfluctuation of accommodation according to  claim 1 , wherein said first sensing element is an attachable electrode or an adhesive electrode pad. 
     
     
         8 . The method for measuring microfluctuation of accommodation according to  claim 1 , wherein said processing module is arranged in a computer, a mobile Internet-access device, a portable device, or a far-end server.
