Update copyright information

2011-04-28T16:43:16+00:00

The license information was always right, but the copyright information for this particular project was never quite right. Corrected with this patch. No functional changes. Signed-off-by: Henrik Rydberg

Introduce touch gesture events

2011-03-28T20:02:11+00:00

Touch gesture events follow the same logic as drags, except they cannot be held back but are emitted immediately. Signed-off-by: Henrik Rydberg

Introduce activation hold time

2011-03-14T11:55:19+00:00

Do not activate a drag, pinch or rotate immediately, even if the activation threshold is met. This allows for a smoother transition between fingers. Signed-off-by: Henrik Rydberg

Introduce gesture timeouts

2011-03-14T11:55:19+00:00

The timeout of a gesture is integral to the gesture type. This patch introduces timeout per gesture type, potentially enabling more control over gesture timing aspects. The timeout logic replaces the recently added recognition state. Signed-off-by: Henrik Rydberg

Fix tap event leakage

2011-03-14T11:55:19+00:00

As an earlier stabilizing measure, very short taps were not registered as such but discarded, potentially letting the touch information through as non-gesture events. This should rather be handled in utouch-frame, and thus the code his dropped here. [rydberg@euromail.se: folded in unused code removal] Signed-off-by: Chase Douglas Signed-off-by: Henrik Rydberg

Replace touch logic with utouch frame engine

2011-01-02T11:39:07+00:00

The original grail uses an internal touch framework and exports some touch information as extended attributes to gesture events. This was never quite the intention, but rather to expose gestures and touches on a similar footing, such that grail can be input agnostic. This patch starts off by replacing the internal touch framework with the utouch-frame engine. Signed-off-by: Henrik Rydberg

Add tap state to the tapping model

2010-09-21T10:56:17+00:00

Add the ability to read off the tap state in the tapping model. Useful for emulation i lieu of tapping gestures. Signed-off-by: Henrik Rydberg

Do not tap when leaving fingers on the pad

2010-09-21T10:56:17+00:00

The current code will treat a 3-down-2-up as a tap. This patch changes the logic so that taps are only emitted when the number of fingers returns to the baseline. Signed-off-by: Henrik Rydberg

Inhibit taps immediately after a finger is lifted

2010-09-10T12:06:10+00:00

The intentional tap starts with a finger in the air. This patch treats the sequence up-down-up as unintentional, unless performed with a single finger. Fixes the problem with accidental taps during multi-finger gestures. Signed-off-by: Henrik Rydberg

Introduce tapping from any finger configuration

2010-08-26T14:29:01+00:00

The current code only emits taps from zero fingers to N fingers. This patch introduces tapping from any prior finger configuration. A tap is defined as an increased number of fingers followed by a decrease within the tap timeout. A tap is reported as the maximum number of fingers present during the tap sequence.
