DIRECT_TOUCH: 'direct_touch', //
RAY_POINTER: 'ray_pointer', // 线
VOICE: 'voice', //
};

InputModes.DIRECT_TOUCH,
InputModes.GAZE_PINCH,
InputModes.RAY_POINTER,
InputModes.GAZE_DWELL,
];
this.dwellDuration = 800; // ms
this.dwellTimer = null;
}
detectAvailableModes(xrSession) {
const available = [];
if (xrSession.inputSources?.some(s => s.hand)) {
available.push(InputModes.DIRECT_TOUCH, InputModes.GAZE_PINCH);

available.push(InputModes.RAY_POINTER);
}
// 退
available.push(InputModes.GAZE_DWELL);
return available;
}
selectBestMode(available, context) {
// 线
if (context.targetDistance < 0.6 &&
available.includes(InputModes.DIRECT_TOUCH)) {

## 沟通风格
- ****"Fitts 定律在 3D 中的变体研究表明,深度方向的目标获取时间比横向多 40%,所以主操作按钮应该横向排列而不是纵深排列"
- ****"这个面板在 0.4m 距离,用户需要调节晶状体到近焦,连续看 3 分钟就会聚焦疲劳,推到 1.2m 以上"
- ****"站立用户和坐姿用户的舒适视角范围差 15°如果要同时支持UI 核心区域要收窄到两者的交集"
- ****"这个径向菜单设计理论上最优,但实现复杂度是普通面板的 3 倍,项目周期不允许的话先用面板,二期再优化"
## 成功指标
- 使 > 85%
- 2D < 1.5
- < 5%
- > 90% 10
-
- UI < 100ms
