性能指标中视觉效果和交互沉浸感直接影响用户的VR体验，其中视场角和追踪度对于分析VR设备体验具有重要参考意义。视场角越大，同一分辨率下视野范围更广；追踪度越高，沉浸感越深入。

VR设备视觉效果和交互沉浸感技术指标一览

影响维度

技术指标

影响度

视觉效果

单眼屏幕

分辨率分辨率越高，其画面拟真度越高，画面越清晰。

视场角FOV

视场角的大小决定了光学仪器的视野范围，并不是越大越好，需要在沉浸感和清晰度之间妥协。

角分辨率PPD

每弧度上有多少个像素点，数值越高，显示密度就越高，拟真度就越高。

可变焦显示

支持眼球追踪，屏幕部分支持移动，可变焦屏幕能够更自然的聚焦，看清VR中距离更近的物体。

交互沉浸感

追踪定位

inside-out：VR头显上安装摄像头检测外部环境变化，借助计算机或者自身的算法芯片计算出VR头显的空间位置。

outside-in：外接定位器/摄像头，精确度高，传输资料量少，但自由活动空间受限。

眼动交互

通过眼球追踪等方式，在VR社交中提升沉浸感。

声音交互

功能上分为语音交流和语音识别控制，可通过个性化沉浸声提升沉浸感。

触觉交互

当前标准为带按钮和震动反馈的6DoF手柄，可通过精细化触觉反馈提升沉浸感。

移动交互

如通过重定向行走，在有限的房间内创造出无限大的VR空间。

①视觉效果：分辨率、PPD、视场角和可变焦显示四个因素影响画面质量与拟真度；

?②交互沉浸感：追踪定位、眼动交互、声音交互、触觉交互与移动交互等影响用户体验过程的舒适度和沉浸感；除了设备以外，网络传输和渲染计算能力也会影响计算处理速度和复杂度，从而带来更流畅娱乐体验。中国信通院《5G云化虚拟现实白皮书》将VR沉浸感分为四个程度，目前VR主流设备已能达到部分沉浸状态，单眼分辨率满足1.5k-2k，视场角达100-120度，追踪定位基本采用inside-out。部分杀手级产品，如Oculusquest，已加入手部追踪，且发布了多项眼球追踪专利，预期在下一代产品HalfHome中实现眼球追踪，深度沉浸指日可待。
