Device and method for evaluating brainwave performance of portable electronic device in real time

Abstract

The invention provides a device for evaluating brainwave performance of a portable electronic device in real time, which comprises a signal acquisition module, a central processing module, an operation module, a memory module and a display module, wherein the signal acquisition module is used for acquiring brainwave signals broadcast by a product to be tested; the central processing module is used for analyzing the brainwave signals; the operation module is used for operating the analysis result and integrating with theoretical brainwave signal data; the memory module is used for storing the theoretical brainwave signal data; the display module is used for displaying the test result; the signal acquisition module is connected with the central processing module; the central processing module is connected with the operation module; the memory module is connected with the operation module; and the display module is connected with the central processing module. By using the method, the test process is fast and convenient, the manual intervention is not required, and the test result can be displayed in real time. Besides, the ultimate result of the evaluation and test report can be displayed immediately after the brainwave signals of the device to be tested are broadcast.

Description

technical field [0001] The invention relates to a real-time acquisition method of a portable device, in particular to a device and method for real-time evaluation of the electroencephalogram performance of a portable electronic device. Background technique [0002] At present, the products on the market are basically brainwave playback products, and there is no simple and low-cost brainwave performance evaluation test product. The traditional EEG performance evaluation test basically adopts the following two types of methods: one is through large-scale comprehensive test instruments, such as oscilloscopes, signal analyzers, etc. However, since this type of instrument is not dedicated to brainwave testing, the test is inconvenient. The test results often need to be sorted out and calculated by humans, and the test speed cannot meet the needs of brainwave testing. It relies heavily on people and cannot be convenient and fast Unattended test; the second is to record the brain ...

Problems solved by technology

However, since this type of instrument is not dedicated to brainwave testing, the test is inconvenient. The test results often need to be sorted out and calculated by humans, and the test speed cannot meet the needs of brainwave testing. It relies heavily on people and cannot be convenient and fast Unattended test; the second is to record the brain wave signal of the product under test as an audio file through the recording device, and then use the audio editing software on the PC side to manually analyze and calculate and organize the brain wave performance data. This method can be done in the testing stage Unattended, but the manual workload of data analysis and sorting in the later stage is still relatively large, and it still cannot achieve our original intention of quickly evaluating and testing brainwave performance
