Abstract: Virtual environments may be presented to a user with an inclusion of one or more applications, but many such techniques for integrating the applications with the virtual environment may exhibit disadvantages. For example, a two-dimensional “flat” rendering of the application may require a loss of visual depth, and/or may appear inconsistent; an immersive presentation that is mutually exclusive with the presentation of the virtual environment may achieve very limited integration; and a holographic presentation may appear incongruous. Such techniques may also increase presentation latency, with noticeable and significant consequences. Instead, the virtual environment may define an application region, and may notify the application of the application region and a perspective of the user within the virtual environment.

Abstract: In one embodiment, a user interface system may execute an independent expression in a secondary code set to facilitate taking a dynamic object reading for a target composition object. The user interface system may execute a primary code thread and a secondary code thread for a user interface. The primary code thread may generate an independent expression resident in the secondary code thread. The independent expression may gather an input set resident in the secondary code thread for a target composition object. The secondary code thread may render the target composition object based on the input set.

Abstract: A latency between an input and its corresponding feedback can be reduced by generating the feedback in a lower-layer software component instead of in an upper-layer software component. The lower-layer component generates the feedback based on one or more parameters associated with a given input type. The parameters were previously created based on, for example, one or more previous inputs. Generating feedback in a lower-layer component reduces the number of software layer boundaries that the input and feedback pass through, thus reducing the latency between the feedback and input.

Abstract: Aspects of a user interface that provides visual feedback in response to user input. For example, boundary effects are presented to provide visual cues to a user to indicate that a boundary in a movable user interface element (e.g., the end of a scrollable list) has been reached. As another example, parallax effects are presented in which multiple parallel or substantially parallel layers in a multi-layer user interface move at different rates, in response to user input. As another example, simulated inertia motion of UI elements is used to provide a more natural feel for touch input. Various combinations of features are described. For example, simulated inertia motion can be used in combination with parallax effects, boundary effects, or other types of visual feedback.
