Method and device to reduce swipe latency

摘要

A plurality of methods 600-800 that collectively reduces touch swipe latency within a user interface (210) of an electronic device 100/200 includes: activating 610 a predictive touch utility 120; and in response to detecting 710 a sliding movement of an external manipulator 165 from a set of prior positions on a touchpanel 148 to a current position on the surface: dynamically computing 712 a predicted next position 392 based on the set of prior positions and the current position, before the external manipulator 165 arrives at an end position 240 while continuously touching the surface; and triggering 714 advancement of 536 the user interface 210 to a predicted next frame corresponding to the predicted next position 392. Activating the predictive touch utility 120 includes selecting and loading 612 a predictive touch profile 134 having a response curve 1500/1600 that correlates to gains applied to compute the predicted next position 392.

1. A method comprising:
loading, by an electronic device, a predictive touch profile from a plurality of predictive touch profiles stored on a storage component of the electronic device; receiving, by an electronic device, an indication of a user input detected by a touch panel, the user input comprising a sliding movement traversing a set of prior locations on the touch panel to a current location on the touch panel responsive to receiving the indication of the user input:
while the user input is being detected by the touch panel, dynamically determining, by the electronic device, based on the set of prior locations and the current location, and using the predictive touch profile, a predicted next location of the user input on the touch panel, wherein each predictive touch profile from the plurality of predictive touch profiles is associated with a different response curve that correlates to a series of gains that are applied to sliding movements when dynamically determining the predicted next location; andtriggering, by the electronic device, an advancement of a user interface to a predicted next frame corresponding to the predicted next location.
