With the development of science and technology and the intensification of the aging of the world’s population, elderly care robots have begun to enter people’s lives. However, the current elderly care system lacks intelligence and is just a simple patchwork of some traditional elderly products, which is not conducive to the needs of the elderly for easy understanding and easy operation. Therefore, this paper proposes a flexible mapping algorithm (FMFD), that is, a gesture can correspond to a flexible mapping of multiple semantics in the same interactive context. First, combine the input gesture with the surrounding environment to establish the current interactive context. Secondly, when the user uses the same gesture to express different semantics, the feature differences formed due to different cognitions are used as the basis to realize the mapping from one gesture to multiple semantics. Finally, four commonly used gestures are designed to demonstrate the results of flexible mapping. Experiments show that compared with the traditional gesture-based human-computer interaction, the proposed flexible mapping scheme greatly reduces the number of gestures that users need to remember, improves the fault tolerance of gestures in the human-computer interaction process, and meets the concept of elderly caregiver robots.

护航机器人意图柔性映射算法研究

随着科学技术的发展和世界人口老龄化的加剧，养老机器人已经开始进入人们的生活。然而，目前的老年人护理系统缺乏智能，只是一些传统老年人产品的简单拼凑而成，不利于老年人对易懂，易操作的需求。因此，本文提出了一种灵活的映射算法（FMFD），即一个手势可以对应于同一交互上下文中多种语义的灵活映射。首先，将输入手势与周围环境相结合，以建立当前的交互上下文。其次，当用户使用相同的手势来表达不同的语义时，以不同的认知所形成的特征差异为基础，实现了从一种手势到多种语义的映射。最后，设计了四种常用手势来演示灵活映射的结果。实验表明，与传统的基于手势的人机交互相比，该灵活的映射方案大大减少了用户需要记住的手势数量，提高了人机交互过程中手势的容错能力，满足了该概念。老年人护理机器人。
