Some embodiments provide a device, method, system, computer program product and user interface for pointer movement analysis with modal continuous controller conversion. Specifically, some embodiments adapt movements issued from a mouse input device, trackpad, or touchscreen to adjust a position of a UI element. Some embodiments analyze a first set of movements and adapt a subsequent second set of movements to adjust the position of the UI element within a range of UI element positions when the first set of movements satisfies a movement threshold. The movement threshold includes a spiral pattern. In some embodiments, adjusting the position of the UI element includes performing scrolling within a scroll area based on the second set of movements when the first set of movements satisfies the spiral pattern.

Movement analysis is expanded to assist not just in determining the emotional, cognitive, and performance processes of subjects, but to also predict and explain a subject's actions. The analysis is particularly applicable to leaders, but may be applied to other subjects. Additionally, non-expert practitioners may more readily benefit from analyzing a subject's movements.

Emitter target range and heading are estimated from bearing measurements enhancing bearings-only estimator convergence to a target track, and permitting optimization of an observer position relative to the target at the end of the total bearing measurement period. One or more estimates of the target range, speed and heading made from bearing measurements before an observer maneuver are used to determine the most appropriate observer maneuver giving complete bearings-only target-motion-analysis observability. A set of parameters characterizing a set of potential emitter signal sources is generated based on measured emitter characteristics. A most probable set of emitter platforms is identified and the emitter operating mode and corresponding platform set are associated with a kinematic regime set. A specific speed or discrete set of speeds best adapted to a set of all possible platform missions, emitter speed as a continuous function of emitter range, and emitter range are all determined.
