理解二维（2D）视频中运动和姿势的时间变化并不容易，导致用户重复观察以理解它们。然而，依赖于时间轴表示的视频接口（其取决于人的记忆）使得用户难以观察运动，因为它们缺乏原始运动信息。因此，我们提出了一个运动搜索圆作为头戴式显示器的用户界面。他们在三维空间中的一个圆圈上的视频中可视化运动，用轨迹和人形模型表示时间和空间的变化。这个自动生成的圆圈与2D视频相结合，提供了运动的视觉概览。我们的用户测试和研究显示了在个人培训环境中的概念证明。结果表明，所提出的方法是很容易学习的未经培训的人。通过创建运动的视觉概述，我们打算解决传统的视频学习困难。
Understanding the temporal changes of movement and posture in two-dimensional (2D) videos is not easy, leading users to repeat observations to understand them. However, the video interface relying on timeline representations, which depend on one’s memory, makes it hard more than necessary for a user to observe movements because they lack original motion information. Therefore, we propose a Motion Seek Circle as a user interface for Head-Mounted Displays. They visualize the motion in a video on a circle in three-dimensional space, representing temporal and spatial changes with trails and humanoid models. This automatically generated circle combined with a 2D video provides a visual overview of the movement. Our user test and study show proof of concept in a personal training context. Results indicate the proposed method is easily learnable for untrained people. By creating a visual overview of movements, we intend to solve traditional video-learning difficulties.
