Python和游戏的新手。pygame有没有LSL (实验室流媒体层)的包装器?我想创建一个使用EEG信号的游戏来创建一个脑机接口应用程序。任何帮助都将深表感谢。谢谢!:)

Python有一个名为pylsl的LSL模块。您应该能够将其合并到您的游戏循环中。
以下代码改编自this example
from pylsl import StreamInlet, resolve_stream
import pygame
# first resolve an EEG stream on the lab network
streams = resolve_stream('type', 'EEG')
# create a new inlet to read from the stream
inlet = StreamInlet(streams[0])
# Pygame setup
pygame.init()
size = width, height = 320, 240
screen = pygame.display.set_mode(size)
samples = []
while True:
# get a new sample (you can also omit the timestamp part if you're not
# interested in it)
# Get a sample from the inlet stream
sample, timestamp = inlet.pull_sample()
samples.push(sample)
#TODO: interpolate streamed samples and update game objects accordingly.
# You'll probably need to keep a few samples to interpolate this data.
#TODO: draw game
...
pygame.display.flip()

增加了另一种可能性:日内瓦基础校园生物技术的工程师使用LSL创建了一个图书馆,用于使用脑电图的在线范例,称为NeuroDecode
。它依赖于pylsl
并提供更高级别的实现。
在我的fork版本中,我放弃了(旧的)解码功能,转而支持对低级功能的改进,例如信号采集/可视化。
