    • A “Constrained Predictive Interface” uses predictive constraints to improve accuracy in user interfaces such as soft keyboards, pen interfaces, multi-touch interfaces, 3D gesture interfaces, EMG based interfaces, etc. In various embodiments, the Constrained Predictive Interface allows users to take any desired action at any time by taking into account a likelihood of possible user actions in different contexts to determine intended user actions. For example, to enable a virtual keyboard interface, various embodiments of the Constrained Predictive Interface provide key “sweet spots” as predictive constraints that allow the user to select particular keys regardless of any probability associated with the selected or neighboring keys. In further embodiments, the Constrained Predictive Interface provides hit target resizing via various piecewise constant touch models in combination with various predictive constraints. In general, hit target resizing provides dynamic real-time virtual resizing of one or more particular keys based on various probabilistic criteria.
    • “约束预测接口”使用预测约束来提高诸如软键盘,笔接口,多点触摸界面,3D手势接口,基于EMG的接口等用户界面的准确性。在各种实施例中,约束预测接口允许用户采取 通过考虑在不同上下文中可能的用户动作的可能性来确定预期的用户动作,在任何时候执行任何期望的动作。 例如,为了启用虚拟键盘接口,约束预测接口的各种实施例提供关键的“甜点”作为预测约束,其允许用户选择特定的密钥,而不管与所选择的或相邻的密钥相关联的任何概率如何。 在另外的实施例中,约束预测接口通过各种分段常数触摸模型结合各种预测约束提供命中目标调整大小。 一般来说,命中目标调整大小基于各种概率标准提供一个或多个特定键的动态实时虚拟调整大小。
