Title
(ZH) 听觉事件相关电位测量系统及其装置、方法与计算机程序
Abstract
(ZH)

本发明的用于听觉评价的听觉事件相关电位测量系统中,为了抑制清醒度的变化引起的听觉事件相关电位的变动,高精度地测量听觉事件相关电位,除了听觉刺激以外还以被认为适当的尺寸呈示影像,从而降低用户的清醒度的变化。本发明的听觉事件相关电位测量系统具备:尺寸决定部,其决定影像中的区域的尺寸,以使得呈示给用户的影像中的区域的对角的视角具有大于2度小于14度的范围;影像输出部,其对用户呈示包含由尺寸决定部决定的大小的区域的影像;听觉刺激生成部,其在向用户呈示影像的期间内向用户呈示听觉刺激;生物体信号测量部,其测量用户的脑电波信号;和脑电波处理部,其以呈示听觉刺激的时刻为起点来从脑电波信号获取事件相关电位。
