Ubiquitous augmented reality (UAR) implementation can benefit smart shop floor operations significantly. UAR from a user’s first-person view can support and provide the user with suitable and comprehensive information without him/her being distracted from ongoing tasks. A natural hand-based interaction interface, namely, a mobile bare-hand interface (MBHI), is proposed to assist a user in exploring and navigating a large amount of information for a task in the user’s first-person view. The integration of a smart shop floor and UAR-based MBHI is particularly challenging. A real shop floor environment is composed of challenging conditions for the implementation of UAR, e.g., messy backgrounds and significant changes in illumination conditions. Meanwhile, the MBHI is required to provide precise and quick responses to minimize the difficulty of a user’s task. In this study, a wearable UAR system integrated with an MBHI is proposed to augment the shop floor environment with smart information. A case study is implemented to demonstrate the practicality and effectiveness of the proposed UAR and MBHI system.

3D徒手交互可实现与智能对象的无处不在的交互

无处不在的增强现实（UAR）实施可以使智能车间操作显着受益。从用户的第一人称视角来看，UAR可以为用户提供适当而全面的信息并为其提供支持，而不会分散他们正在进行的任务。提出了一种自然的基于手的交互界面，即移动的裸手界面（MBHI），以帮助用户在用户的第一人称视角中探索和导航任务的大量信息。智能车间和基于UAR的MBHI的集成特别具有挑战性。实际的车间环境由实施UAR的挑战性条件组成，例如杂乱的背景和照明条件的重大变化。与此同时，MBHI需要提供精确而快速的响应，以最大程度地减少用户任务的难度。在这项研究中，提出了一种与MBHI集成的可穿戴UAR系统，以通过智能信息扩展车间环境。通过案例研究来证明所提出的UAR和MBHI系统的实用性和有效性。
