Systems and methods are described for displaying 360-degree video using a viewing direction and/or a viewpoint position that is determined based on a user-selected level of automation. If full automation is selected by the user, the viewing direction and/or viewport position is determined by a defined viewing path. If partial automation is selected, the viewing direction and/or viewport position is determined by user input in combination with the defined viewing path. For example, a high-pass-filtered version of the user input may be added to the defined viewing path to obtain a partially-automated viewing direction and/or viewpoint position. Example systems and methods may be implemented using a head-mounted display (HMD). 描述了用于使用基于用户选择的自动化级别确定的查看方向和/或视点位置来显示360度视频的系统和方法。如果用户选择完全自动化，则查看方向和/或视口位置由定义的查看路径确定。如果选择部分自动化，则通过用户输入结合所定义的查看路径来确定查看方向和/或视口位置。例如，可以将用户输入的高通滤波版本添加到所定义的查看路径以获得部分自动化的查看方向和/或视点位置。示例系统和方法可以使用头戴式显示器(HMD)来实现。
