Abstract: Various embodiments enable target disambiguation and correction. In one or more embodiments, target disambiguation includes an entry mode in which attempts are made to disambiguate one or more targets that have been selected by a user, and an exit mode which exits target disambiguation. Entry mode can be triggered in a number of different ways including, by way of example and not limitation, acquisition of multiple targets, selection latency, a combination of multiple target acquisition and selection latency, and the like. Exit mode can be triggered in a number of different ways including, by way of example and not limitation, movement of a target selection mechanism outside of a defined geometry, speed of movement of the target selection mechanism, and the like.

Abstract: User input interpretation mechanisms can pass along user input without delay by initially treating it as freeform movement and passing it along unmodified, rather than waiting to receive a sufficient quantity of user input from which to derive a user's intentions. User input within a defined range from an initial point is freeform movement, passed along unmodified, while user input beyond that range can be confined to a groove if it evidences an intention to move in a precisely linear manner. Grooves can be established to aid in precise vertical movement, with no horizontal deviations, precise horizontal movement, with no vertical deviations, or any other orientation. Before being passed along, user input in groove regions can be modified to center the input within the groove region and eliminate human inaccuracies, such as slight deviations to either side. User input can escape groove regions by moving orthogonally to them.
