Studies of Body-Environmental Informations (Affordances): An longitudinal observations on Severe movement

我们做了两种研究。1)观察有麻痹症状患者在ADL康复过程中穿袜子动作的发展。我们的目的是揭示哪些身体环境信息可以用于关联和改进动作，以及如何将许多动作组织成整个动作过程，以及使用和选择了哪些动作模式。动作过程的组织和模式的变化表明，患者同时探索支撑躯干的姿势和手法，以及这些手法的变化。结果表明，穿袜子是基于这种姿势（同步姿势），它是产生新动作模式的身体环境信息的来源。2)制作了Baby电影数据库。在这个系统中，记录了2001年秋天出生的两个男婴从出生到三岁的日常行为。从150小时的录像中提取了940个电影场景。我们在每部电影中添加了几个关键词，以关注婴儿周围的环境。例如“ground”、“steps”和“hole”等。用户可以使用本系统制作自己的宝宝成长纪录片。这对机器人和其他工程领域很有用。

We did two kinds of researches. 1)Observing a development of putting on socks action performed by patient with suffering from paralytic symptom in rehabilitation of ADL. Our purpose is to reveal what body-environmental information are available to relate and improve the action and how organized many movements into whole process of action and what patterns of action were used and selected. Organization of action process and variations of patterns showed that the patients explored posture supporting trunk and manipulation simultaneously and change of such varied some kinds of manipulation. Results suggests that putting on socks is based on this posture( simultaneous posture) and it is source of body-environmental information of generating new patterns of actions. 2)We made a Baby movie data-base. In this system, the everyday actions of two male infants born in fall 2001 are captured from birth to three years of age. 940 movie scenes are extracted from 150 hours of video recording. We added several keywords to each movie to focused on the environment surrounding the babied. For examples are 'ground', 'steps' and 'hole' etc. To use this system user make their own documentary of baby's development. It's will useful for Robotics and other engineering areas.
