Methods of controlling the display and use of a UI element are disclosed. In an embodiment, the UI element may configured so that it initially maintains a topmost position but eventually allows other applications to assume the topmost position. In an embodiment, the display of the element may be adjusted in response to an input so that the UI element is not visible on the display. In an embodiment, the use of the UI element may allow for seamless dragging of the UI element even if the user inadvertently fails to make consistent contact with the touch-sensitive display while dragging the UI element.

Assisting user interface element use

A method for rejecting an unintentional palm touch is disclosed. In at least some embodiments, a touch is detected by a touch-sensitive surface associated with a display. Characteristics of the touch may be used to generate a set of parameters related to the touch. In an embodiment, firmware is used to determine a reliability value for the touch. The reliability value and the location of the touch is provided to a software module. The software module uses the reliability value and an activity context to determine a confidence level of the touch. In an embodiment, the confidence level may include an evaluation of changes in the reliability value over time. If the confidence level for the touch is too low, it may be rejected.

Unintentional touch rejection

The inertia system provides a common platform and application-programming interface (API) for applications to extend the input received from various multi-touch hardware devices to simulate real-world behavior of application objects. To move naturally, application objects should exhibit physical characteristics such as elasticity and deceleration. When a user lifts all contacts from an object, the inertia system provides additional manipulation events to the application so that the application can handle the events as if the user was still moving the object with touch. The inertia system generates the events based on a simulation of the behavior of the objects. If the user moves an object into another object, the inertia system simulates the boundary characteristics of the objects. Thus, the inertia system provides more realistic movement for application objects manipulated using multi-touch hardware and the API provides a consistent feel to manipulations across applications.

Multi-touch object inertia simulation

The manipulation system described herein provides a common platform and application-programming interface (API) for applications to communicate with various multi-touch hardware devices, and facilitates the interpretation of multi-touch input as one or more manipulations. Manipulations map more directly to user intentions than do individual touch inputs and add support for basic transformation of objects using multiple touch contacts. An application can use manipulations to support rotating, resizing, and translating multiple objects at the same time. The manipulation system outputs two-dimensional (2D) affine transforms that contain rotation, scale, and translation information. Thus, using the manipulation system the application author can focus more on building touch-capable applications and let the manipulation system handle the underlying transformations and communication with the multi-touch hardware.

Multi-touch manipulation of application objects

A tablet PC having an interactive display, which is touchscreen enabled, may be enhanced to provide a user with superior usability and efficiency. A touchscreen device may be configured to receive multiple concurrent touchscreen contacts. The attributes of the multiple concurrent touchscreen contracts may be mapped to operations performed on the computing device. As a result, a user can trigger the execution of the toggle accessibility aid operation and the screen rotation operation with greater convenience. Moreover, the tablet PC may be configured to map an operation to a hand gesture or input.

Multi-touch uses, gestures, and implementation

Aspects of the subject matter described herein relate to paragraph snapping. In aspects, trending data is collected and prepared for sending to one or more target machines. Upon receiving the trending data, a target machines installs the trending data locally and deletes previously installed trending data. After installation, the trending data may be used to suggest text in response to input from a user. If a user selects suggested text, the text may be added to a local dictionary of the target machine.
