The requested equipment consists of two identical camera-to-computer packages for video recording and two items needed for video editing. This equipment augments the PI's existing research facility and makes possible the multidisciplinary examination of the production and perception of communicative behavior undertaken by the P.I. and his collaborators at UBC. The camera package is state of the art for professional digital video recording; yet inexpensive, mobile, and well-suited for examining 1) the multimodal production and multisensory perception of spoken language as it occurs both naturally and spontaneously and as mediated through machine interfaces, 2) the behavior of young children and infants as they interact with their environment and 3) communicative interaction in spoken and musical performance.   The proposal is well-timed. After more than 10 years of development, we now have software tools for acquiring accurate measures of biological motion from video image sequences. These tools replace physically restrictive marker-based motion capture systems, making it possible, for example, to measure the motion of small children. Using multiple cameras in conjunction with  non-invasive force plates, the motions of the face, head, and body can now be simultaneously measured for multiple participants in a communicative interaction. Recent NSERC awards to the PI and Fels (with the PI as co-applicant) explicitly require such recordings.   The two camera packages each consist of 1) a high definition camera (Panasonic AG-HPX500), lens (Canon KJ16ex7.7 KRSD) and accessories, 2) a hardware video encoder (AJA IOHD) that compresses high definition video in real time without introducing artifacts or loss of image quality and 3) an Apple MacBookPro that writes the compressed video directly to disk via Apple's Firewire 800 linked to the AJA. This system has more than twice the spatial and temporal resolution of standard video, making possible the accurate measurement of hand and face motion. Finally, for video editing, we request an Apple monitor (Cinema HD) and software (Final Cut Studio) that will be installed on an existing workstation. Total funds needed are $91,041.

所要求的设备包括两套相同的摄像机-电脑录像设备和两套录像编辑设备。该设备增强了PI现有的研究设施，并使PI对沟通行为的产生和感知进行多学科检查成为可能。和他在UBC的合作者相机包是最先进的专业数字视频录制;但价格低廉，移动的，并且非常适合于检查1）口语的多模态产生和多感官感知，因为它自然地和自发地发生并且通过机器接口介导，2）幼儿和婴儿与环境互动时的行为; 3）口语和音乐表演中的交流互动。 这项提议来得正是时候。经过10多年的发展，我们现在已经有了从视频图像序列中获取生物运动精确测量的软件工具。这些工具取代了物理限制性的基于标记的运动捕捉系统，使其成为可能，例如，测量儿童的运动。使用多个摄像头结合非侵入式测力板，现在可以同时测量多个参与者的面部、头部和身体的运动。最近NSERC授予PI和Fels（PI作为共同申请人）明确要求此类记录。 这两个相机包各包括1）一个高清相机（Panasonic AG-HPX 500），透镜（Canon KJ16ex7.7 KRSD）和配件，2）硬件视频编码器（AJA IOHD），其以真实的时间压缩高清晰度视频而不引入伪影或图像质量损失，以及3）一个苹果MacBookPro，通过连接到AJA的苹果Firewire 800将压缩视频直接写入磁盘。该系统具有两倍以上的空间和时间分辨率的标准视频，使手和面部运动的准确测量成为可能。最后，对于视频编辑，我们要求在现有工作站上安装Apple显示器（Cinema HD）和软件（Final Cut Studio）。所需资金总额为91 041美元。
