Acquisition Of An EEG-Based Imaging System For Human-Computer Interface Research

在国家科学基金会的支持下，在Malek Kouadi博士的指导下，佛罗里达国际大学将购买一个神经扫描电信号成像ESI-256通道EEG/EP系统和一个较小的接口单元，一个红外眼球凝视跟踪开发系统。ESI-256是同类产品中第一个商用EEG和诱发电位（EP）系统。它允许同时显示所有通道的平均和原始EEG以及后处理、源定位和与三维数据集（如MRI）的配准。该系统包括：一个ESI阅读器工作站，带有光驱和与主ESI系统的局域网（LAN）连接;一个神经扫描STIM系统，与ESI连接，用于诱发电位和认知事件相关电位测试;一个咖喱多模态神经成像软件，用于将EEG/EP测量与MRI和CT模态集成。来自LC技术的红外线眼睛注视跟踪系统将与更大的系统接口，以允许眼睛注视与与准备电位相关的大脑活动的整合。 该研究的目标是开发一种替代形式的脑机接口，由身体自然产生的信号驱动。这对于大量在使用计算机方面受到身体限制的个人来说尤其重要。在人机界面的发展过程中，人们希望接近这样一个点，即人类可以使用使他们的正常活动活跃起来的信号来与这种机器进行交互。通过对大脑内部结构和眼球运动发起的自愿运动命令的研究，Dr. Ravouadi和他的同事们将致力于开发这样一个系统。 - - v- +- ±@ + _ 你好，我的天啊 Ý + Õ $ H L + ¢ ╗ D H + R:\WWUSER\TEMPLATE\NORMAL.DOT

With National Science Foundation support and under the direction of Dr. Malek Adjouadi, Florida International University will purchase a Neuro Scan Electrical Signal Imaging ESI-256 Channel EEG/EP system and a smaller interface unit, an infrared eye-gaze tracking development system. The ESI-256 is the first commercially available EEG and evoked potential (EP) system of its kind. It permits simultaneous display of average and raw EEG of all channels and post-processing, source localization and co-registration with three-dimensional data sets such as MRI. The system includes: an ESI Reader Station with optical drive and local area network (LAN) connection to the main ESI system; a Neuro Scan STIM System interfaced to ESI for evoked potential and cognitive event-related potential testing; a Curry Multimodal Neuro-imaging software for integration of EEG/EP measurements with MRI and CT modalities. An infrared eye-gaze tracking system from LC Technologies will be interfaced with the larger system to allow the consolidation of eye-gaze with brain activities associated with readiness potentials. The goal of the research is to develop an alternative form of brain-computer interface which is driven by the signals generated naturally by the body. It is particularly important for the large number of individuals who are physically limited in their access to computers. In the evolution of human - computer interfaces one hopes to approach the point where humans could use the signals that animate their normal activities to interact with such machines. Though study of voluntary movement commands initiated in the inner structures of the brain and through eye movement, Dr. Adjouadi and his colleagues will work to develop such a system. - À- v- +- ±@ + _ Ûª▓ ÑOh ª' +'ª▒0 Ý + Õ $ H l + ¢ ╗ D h + R:\WWUSER\TEMPLATE\NORMAL.DOT
