    • In one embodiment, a method includes sending information to display an image on a screen. A scroll range for the image may be determined based on dimensions of the image. An origin position and an initial tilt of a gyroscope may also be determined for the image. Tilt measurements associated with the presentation of the image may be received as the gyroscope detects changes in tilt. A progress parameter may be determined based on at least the scroll range, the origin position, and the initial tilt. A scrolling presentation of the image may then be rendered based on the progress parameter. The scrolling presentation of the image may be smoothed by applying an RK4 solver to the tilt measurements to eliminate jitter due to hand tremors. A virtual spring effect may also be applied to give the scrolling presentation a bouncy effect as the edge of the image is reached.
    • 在一个实施例中,一种方法包括发送信息以在屏幕上显示图像。 图像的滚动范围可以基于图像的尺寸来确定。 也可以为图像确定陀螺仪的起始位置和初始倾斜。 当陀螺仪检测到倾斜的变化时,可以接收与图像呈现相关联的倾斜测量。 可以至少基于滚动范围,原点位置和初始倾斜来确定进度参数。 然后可以基于进度参数呈现图像的滚动呈现。 可以通过将RK4求解器应用于倾斜测量来消除由于手抖动引起的抖动来平滑图像的滚动呈现。 也可以应用虚拟弹簧效应以在达到图像的边缘时给滚动呈现带来弹性效果。

    • In one embodiment, a method includes sending information to display a visual content; determining a scroll range for the visual content based on dimensions of the visual content; determining an origin position within the visual content from which the visual content is configured to be scrolled, wherein the origin position is determined based on a type of an application associated with the visual content; receiving an initial tilt measurement of a client computing device; receiving a second tilt measurement of the client computing device; determining a progress parameter based on at least the scroll range, the origin position, the initial tilt measurement, and the second tilt measurement; and sending information to scroll the visual content based on the progress parameter.
    • 在一个实施例中,一种方法包括发送信息以显示视觉内容; 基于视觉内容的尺寸确定视觉内容的滚动范围; 确定可视内容被配置为滚动的视觉内容中的原始位置,其中基于与视觉内容相关联的应用的类型来确定原始位置; 接收客户端计算设备的初始倾斜测量; 接收所述客户端计算设备的第二倾斜测量; 基于至少滚动范围,原点位置,初始倾斜测量和第二倾斜测量来确定进度参数; 并根据进度参数发送信息以滚动视觉内容。

    • In one embodiment, a method includes receiving a touch input within a particular region of a display area of the computing device. The display area presents a user interface (UI) including a number of views organized in a hierarchy. One or more of the views has a gesture recognizer configured to process a touch input detected within the regions of the display area associated with each of the views. Each of the views corresponds to one or more regions of the display area. One or more of the gesture recognizers has one or more intervention conditions. A particular one of the views is a default view to process the touch input. The method also includes evaluating the intervention conditions to identify a particular one of the views from among the number of views to process the touch input.
    • 在一个实施例中,一种方法包括在计算设备的显示区域的特定区域内接收触摸输入。 显示区域呈现包括在层次结构中组织的多个视图的用户界面(UI)。 一个或多个视图具有手势识别器,其被配置为处理在与每个视图相关联的显示区域的区域内检测到的触摸输入。 每个视图对应于显示区域的一个或多个区域。 手势识别器中的一个或多个具有一个或多个干预条件。 特定的视图是处理触摸输入的默认视图。 该方法还包括从处理触摸输入的视图数量中评估干预条件以识别特定视图。
