Simulation Design in uniBrain-Speller/StimulationSystem/StimulationProcess /StimulationController.py StimulationController类的loadPics中,visual.ElementArrayStim对象每帧对应颜色计算公式brightness = 0.5 + 0.5 * math.sin( 2 * math.pi * rect.frequency /config.refreshRate * (N-1) + rect.start_phase ),brightness取值范围[0,1]。但是visual.ElementArrayStim在’rgb‘的colorspace内取值范围是[-1,1],意味着最后呈现的刺激是'灰[0,0,0]白[1,1,1]'闪烁,请问这是特意设计的吗?但是《Conformal in-ear bioelectronics for visual and auditory brain-computer interfaces》论文附件视频中实验刺激好像是普通的黑白闪烁刺激?
