Embodiment Construction

[0022] A method for a mobile phone music playing system based on steady-state visual evoked potentials provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific examples.

[0023] The basic principle of the present invention is that when the user needs to operate the mobile phone music player, the user does not need to perform any physical movements, and only needs the user to watch the LCD (or CRT / HDU, etc.) screen and flash at different frequencies The white squares represent different operating instructions. When the user looks at different white squares, a continuous response related to the stimulation frequency (the fundamental frequency or double frequency of the stimulation frequency) will be generated in the visual cortex of the brain. The acquisition device collects the EEG signals online, and through the analysis and processing of the collected EEG signals, the user's operation intention can be obtai...

Abstract

The invention discloses a mobile phone music playing system based on the steady-state visual evoked potential (SSVEP). The mobile phone music playing system includes a visual stimulation module, a signal acquisition module, a signal processing module, a real-time transmission module and a music playing module. The visual stimulation module provides a user with SSVEP evoked potential visual stimulation in an LCD display manner or the like. The signal acquisition module acquires brain electrical signal data and transmits to a data processing program. The signal processing module performs baseline drift removal, filtering, CCA analysis and feature extraction of signals by using the data processing program, and determines a desired operation of the user. The real-time transmission module transmits an analysis result to a mobile phone via the Internet or Bluetooth or WiFi. The music playing module reacts accordingly. The method provided by the invention requires no body movement of the user, the user only needs to watch the LCD, CRT, HDU or other screen, and through analysis of the acquired brain electrical signals, the control of the mobile phone music player by the user can be achieved.

Description

technical field [0001] The invention relates to an input and output technology for interaction between a user and a computer, and belongs to the comprehensive application of the fields of cognitive neuroscience, information technology and automatic control. Background technique [0002] Steady-State Visual Evoked Potentials (SSVEP) is when the human body is subjected to a fixed frequency of visual stimulation, the visual cortex of the brain produces a continuous frequency related to the stimulation frequency (at the fundamental frequency or double frequency of the stimulation frequency) The response of the visual cortex of the brain to the flickering stimulus in the visual center is a kind of biofeedback. Visual homeostasis evoked potentials combined with brain-computer interface systems can be used to help patients who have lost control of their movements realize the operation of intelligent machines. The successful application of these systems has enabled more and more di...
