Instantiable gesture object techniques are described in which native gesture functionality is abstracted to applications using a script-based recognition interface. Gesture objects may be instantiated for different interaction contexts at the direction of applications programmed using dynamic scripting languages. Gesture objects can be configured to designate particular touch contacts and/or other inputs to consider for gesture recognition and a target element of content to which corresponding recognized gestures are applicable. After creation, gesture objects manage gesture processing operations on behalf of the applications including creating recognizers with the native gesture system, feeding input data for processing, and transforming raw gesture data into formats appropriate for the application and/or a target element. Accordingly, script-based applications may use the gesture objects to offload processing tasks associated with gesture recognition and take advantage of native gesture functionality.

Techniques for an input object for routing input for visual elements are described. In at least some embodiments, a region of a display area includes multiple graphic elements that can be generated and/or managed by different graphics functionalities. For instance, a graphical user interface (GUI) for an application can include a primary window and visual elements within the primary window, such as banners, control buttons, menus, Tillable fields, and so forth. In at least some embodiments, the primary window of the GUI can be managed by a first graphics functionality, while one or more visual elements within the primary window can be managed by a second graphics functionality. In accordance with one or more embodiments, an input object is employed to route input to visual elements to a graphics functionality responsible for managing the visual elements.

In one embodiment, a unified pointer messagemay describe in a single type of pointer message a coordinate input from a user via multiple types of pointer devices. An input device interfacemay receive a coordinate inputfrom an input device. A processormay execute an application programming interface layerthat creates a unified pointer messagefor the coordinate input. The processormay send the unified pointer messageto an application. The processormay process a device specific data setunhandled by the application.

The efficient buffering of image data for a plurality of clients is disclosed. One disclosed embodiment comprises an optical touch-sensitive device configured to receive changed portions of a frame of data from a touch data acquisition system comprising a touch-sensitive display, to store the changed portions of the frame of data in a common data frame buffer, and to receive a bitmap header from the touch data acquisition system that specifies locations of the changed portions of the frame of data and store the bitmap header in each of a plurality of client header buffers. Clients can first obtain the bitmap header from buffers corresponding to those clients, and then obtain the changed portions of the frame of data from the common data frame buffer.

A method and system for controlling the spin rate of an optical device. A device driver provides notification that media has been inserted into the optical device. A control service determines the format of information on the media. The spin rate of the optical device is locked or unlocked based on the format.

A system that facilitates the storage of data using a write barrier. The system interfaces to a hardware component that stores data, and includes a write barrier component that dynamically employs instructions compatible with the hardware component to ensure data integrity during storage of the data. The write barrier component is independent of at least an operating system and an application and can operate in a least one of a user mode and a kernel mode. The write barrier component includes at least one of software instructions, routines, and methods, the selection of one or more of which is based on hardware data extracted from the hardware component. A selection component interrogates the hardware component for hardware data to facilitate selection of one or more instructions most suitable for interfacing to the hardware component. A coalescing component combines cache synchronization requests into a single set of instructions, which set is processed to flush a disk cache in one process.
