Abstract: Smoothing of touch input is provided. One example method of smoothing touch input may include calculating an expected window of touch event positions for a current raw touch event position using previous raw touch event positions, and determining if the current raw touch event position is within the expected window of touch event positions. The method may further include, if the current raw touch event position is within the expected window of touch event positions, returning a distance-agnostic smoothed position. The method may also include, if the current raw touch event position is outside the expected window of touch event positions for longer than a tolerated duration, returning a distance-influenced smoothed position.

Abstract: A computing system includes an access prevention module that selectively locks use of one or more system resources of that computing system. A vision-based input module is configured to recognize a data-encoded tag while the access prevention module locks use of the one or more system resources. A lookup module is configured to receive a usage profile identified by the data-encoded tag, and a login module is configured to unlock use of some to all of the one or more system resources in accordance with terms of the usage profile.
