Development of high-accuracy research environment for motion perception.

本研究的主要目的是评估可用于运动知觉研究的研究设备和工具，并通过整合合适的设备和工具来开发一个完整的实验环境。至于图像呈现设备，我们评估了几种机器，包括那些专门用于计算机图形或图像处理的机器，并确定视觉刺激生成器是最适合我们的设备，这是剑桥研究中心为心理物理实验开发的设备。另一种可能性是Macintosh计算机与视频工具箱软件工具相结合，如果亮度分辨率不是关键的话。对于VEP记录，我们开发了一种使用商用放大器和IGOR软件信号处理工具的系统。另一种可能性是使用MacLab，这是一种可以与Macintosh计算机一起使用的专用硬件系统。我们还安装了测力板测量视向和眼动测量装置，建立了一个完整的运动感知系统，具有测量VEP、视向和眼动的能力，并定期进行心理物理测量。该系统在功能上连接到东京大学智能建模实验室的虚拟现实环境(机舱)，以进行大屏幕刺激演示。

The main objective of this study is to evaluate available research equipment and tools for motion perception research and to develop a total experimental environment by integrating suitable equipment and tools. As for image presentation equipment, we evaluated several machines including those dedicated for computer graphics or image processing and decided that Visual Stimulus Generator, a device developed for psychophysical experiment by Cambridge Research was the best for our purpose. Another possibility was Macintosh computer combined with Video Tool Box software tools, if luminance resolution is not crucial. For VEP recording, we developed a system using a commercially available amplifier and Igor, a software signal processing tool. Another possibility was to use MacLab, a dedicated hardware system that can be used with Macintosh computer. We also implemented force plate to measure vection and eye movement measuring device and build up a total system for motion perception with capability of measuring VEP, vection, and eye movement as well as regular psychophysical measurements. The system is functionally connected to the virtual reality environment (CABIN) at the Intelligent Modeling Laboratory at the University of Tokyo for large screen stimulus presentations.
