  4. 输入行为 • 任务循环处理不会受可视化界面影响, 那就是为什么 • 一个键的敲击是在运行时间中的剩余时间(闲置时间)处理,那意味着 • 反映速度取决于可用的资源, 是不确定的. • 然而, 可以用 VA_GetKeyMatrix 功能库调用键影射, 也就是 • 可能再一次实时处理. 在下一页幻灯片中我们会着重阐述这点

  5. Eingabeverhalten ~100ms Real-time

  6. 语言切换

  7. 动态行为 锁定位 设定 不可见的位 设定 状态位 0 0 0 0 0 1 0 1 0 12345 前景 背景 改变颜色

  8. 小结 • 涉及到 VC 编译器的进阶可能和 VISAPI 库的特殊特征和功能. • 每个参与者现在可以按个人要求创建综合的可视化界面.
