Abstract: A computer-implemented method includes receiving user input comprising a gesture on a touchscreen, the gesture having a gesture velocity. The gesture velocity is compared with an inertia movement threshold. Based on the comparing, the gesture is determined to be an inertia gesture. When the gesture velocity is greater than or equal to the inertia movement threshold, simulated inertia is applied to visual information displayed on the touchscreen.

Abstract: A flexible touch-based scrolling system receives user input comprising a gesture on a touchscreen. The system compares the gesture velocity with one or more velocity ranges. For example, the system determines whether the gesture velocity is above a threshold velocity or below a threshold velocity. The system selects between different types of movement (e.g., smooth scrolling movement, page-by-page movement) of the visual information in the user interface, based on the comparison of the gesture velocity with the velocity ranges. For example, the system selects smooth scrolling movement if the gesture velocity is below a threshold velocity, and the system selects page-by-page movement if the gesture velocity is above the threshold velocity.

Abstract: A method of operating a device having a touch-sensitive display includes displaying scrollable information elements on the touch-sensitive display and detecting a touch gesture from an input device on the touch-sensitive display. The touch gesture is classified as a flick gesture. If the flick gesture satisfies at least a first criterion reflecting a user intent to scroll the information elements in a single direction along a first of a pair of cardinal axes, the direction in which the information elements is scrolled is locked along the single direction. If the flick gesture satisfies the first criterion, any displacement of the information elements which has occurred along a second of the cardinal axes orthogonal to the first cardinal axis as a result of classifying the touch gesture as a flick gesture is undone.

Abstract: Multi-dimensional boundary effects provide visual feedback to indicate that boundaries in user interface elements (e.g., web pages, documents, images, or other elements that can be navigated in more than one dimension) have been reached or exceeded (e.g., during horizontal scrolling, vertical scrolling, diagonal scrolling, or other types of movement). A compression effect can be displayed to indicate that movement has caused one or more boundaries (e.g., a horizontal boundary and/or a vertical boundary) of a UI element to be exceeded. Exemplary compression effects include compressing content along a vertical axis when a vertical boundary has been exceeded and compressing content along a horizontal axis when a horizontal boundary has been exceeded.
