    • Electronic devices can identify other nearby devices, and determine the relative positions of those devices, using a combination of techniques. Various devices are able to project one or more instances of a unique identifier, such as a barcode, which can be imaged by other devices. The devices also can communicate position and/or orientation information over a wireless sideband channel. By combining the information relating to the projected identifier with information collected over the sideband channel, devices can automatically determine the location of various devices and associate a user or device identity with those devices. A user of a device then can view relative locations of those devices on a display element, including information about the user of the device. Further, the relative position determinations can enable a user to perform certain functions with respect to another device based at least in part upon the position and/or identity of that device.
    • 电子设备可以识别其他附近的设备,并且使用技术的组合来确定这些设备的相对位置。 各种设备能够投射可由其他设备成像的唯一标识符(例如条形码)的一个或多个实例。 这些设备还可以通过无线边带信道来传送位置和/或取向信息。 通过将与投影标识相关的信息与通过边带通道收集的信息组合,设备可以自动确定各种设备的位置,并将用户或设备身份与这些设备相关联。 然后,设备的用户可以在显示元件上查看这些设备的相对位置,包括关于设备的用户的信息。 此外,相对位置确定可以使得用户能够至少部分地基于该设备的位置和/或身份来执行关于另一设备的某些功能。

    • The pupil locations of a user with respect to a computing device can be determined by capturing one or more images of the user and analyzing those images using a set of pupil detection algorithms. Each algorithm can produce at least one estimated position with an associated confidence value, and this information from each algorithm can be used to determine a probable location of each pupil. In some embodiments, one or more environmental factors can be used to adjust the confidence values or select algorithms based on how the corresponding algorithms perform under those conditions. Similarly, an independence of the various algorithms can be utilized in some embodiments to adjust the confidence levels or weight results based on a level of dependence between those algorithms.
    • 可以通过捕获用户的一个或多个图像并使用一组瞳孔检测算法分析这些图像来确定用户相对于计算设备的瞳孔位置。 每个算法可以产生具有相关联的置信度值的至少一个估计位置,并且来自每个算法的该信息可用于确定每个瞳孔的可能位置。 在一些实施例中,可以使用一个或多个环境因素来调整置信度值或基于相应算法在这些条件下执行的选择算法。 类似地,在一些实施例中可以使用各种算法的独立性来基于这些算法之间的依赖关系水平来调整置信水平或权重结果。

    • Content displayed on a display element of a computing device can be rendered from a viewpoint that updates with changes in the relative position of a user's head, or other such feature, with respect to the device. At least one camera of the device can attempt to track the relative position in order to determine the proper viewpoint. When the user's head can no longer be seen, or when confidence in the determined relative position drops below an acceptable value, for example, the device can utilize information from another source, such as a motion or rotation sensor, to attempt to estimate the current position of the user's head. Physical limitations of the user with respect to the device also can be used to improve the accuracy of the determination.
    • 从计算设备的显示元件上显示的内容可以从用户头部或其他这样的特征相对于设备的相对位置的改变更新的观点呈现。 设备的至少一个摄像机可以尝试跟踪相对位置,以便确定正确的视点。 当使用者的头部不能再被看见时,或者当对所确定的相对位置的置信度低于可接受的值时,例如,该装置可利用来自诸如运动或旋转传感器之类的其它来源的信息来尝试估计当前的电流 用户头部的位置。 用户相对于设备的物理限制也可以用于提高确定的准确性。

    • An electronic device performs functionality adjustments based on a determined attention level of a user of the device. In some embodiments, the device automatically enters a sleep mode upon determining that the user has fallen asleep. The device may automatically modify functionality of the device such that disturbances to the user is minimized or power consumption is reduced. For example, the device may lower the volume of a ring tone or deactivate a communication channel. In some instances, the device may determine that the user is half-awake or paying an intermediate level of attention and activate an intermediate mode where at least some functionality is modified or adjusted. A device subsequently determining that the user is fully awake or actively engaged with the device causes the device to return to a standard mode of operation, where functionality of the device is adjusted to one appropriate for the user's attention level.
    • 电子设备基于设备的用户的确定的关注度来执行功能调整。 在一些实施例中,设备在确定用户已经睡着后自动进入睡眠模式。 设备可以自动修改设备的功能,使得对用户的干扰最小化或功耗降低。 例如,设备可以降低铃声的音量或停用通信信道。 在一些情况下,设备可以确定用户是半醒的或者支付中间级别的关注并且激活至少一些功能被修改或调整的中间模式。 随后设备确定用户完全清醒或主动地与设备接合的设备使得设备返回到标准操作模式,其中设备的功能被调整为适合于用户的注意力水平的功能。
