Abstract: An approach is provided that receives a gesture from a user with the gesture being directed at a graphical user interface element. The gesture is received by the user at a touch-enabled display screen. Emulated physics properties are retrieved that correspond to the selected graphical user interface element. The system detects a speed and a direction from the received gesture and, based on this information, determines an initial trajectory of the selected graphical user interface element. The initial trajectory is adjusted based on the retrieved emulated physics properties with the movement of the element being rendered on the display screen based upon the adjusted trajectory.

Abstract: An approach is provided to join graphical user interface objects into a group. A request is received at a touch-enabled display screen to join a first graphical user interface object with a second graphical user interface object. The request is from a user of the system. The first and second graphical user interface objects are then associated with each other. The first and second graphical user interface objects are displayed on the touch-enabled display screen adjacent to each other and a visual indicator is also displayed near the objects that indicates that the objects have been joined in a group.

Abstract: An approach is provided that renders graphical user interface (GUI) elements, such as tiles or icons, on display screen. Some of the tiles correspond to software functions. User configurable rendering properties are retrieved that correspond to one of the GUI elements. The configurable rendering properties include a shape property or size property. The selected tile is then rendered on the display screen using the rendering properties. A gesture, directed toward the rendered GUI element, is received at the touch-enabled display screen. If the GUI element corresponds to a software function, the software function is launched in response to one or more of the gestures, such as a “tap” gesture.

Abstract: A fingerprint reader (FPR) on a computer is illuminated when an operational context of the computer renders the FPR useful for receiving tactile input from a user.

Abstract: The present disclosure provides apparatuses, systems, and methods involving a spotter apparatus for depositing a substance from a carrier fluid onto a deposition surface in an ordered array, the spotter apparatus comprising a loading surface including a first well and a second well; and a different outlet surface, including a first opening and a second opening, where a first microconduit fluidly couples the first well with the first opening and a second microconduit fluidly couples the second well with the second opening. An overlay is sealed to the outlet surface and penetrated by a deposition channel that is situated to communicate carrier fluid among the first opening, the second opening, and the deposition surface when the overlay is pressed against the deposition surface.
