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 gesture frames

2011-04-28T16:42:33+00:00

This patch extends the API with parallel new/delete functions, aiming to eventually replace the open/close function. The new functions give access to the grail gesture frames, containing gestural transform information. This information is useful in its own right, and will eventually replace the internal recognizer.

Prepare for gesture frame additions

2011-04-28T14:58:51+00:00

Rename internal variables and fix makefile to make room for new targets. Signed-off-by: Henrik Rydberg

Allow replay of device data through grail

2011-04-04T17:46:28+00:00

This patch adds replay capabilities to grail. If the specified device points to a valid evemu file, the device properties will be extracted from that file instead. Any appended event data will be replayed in realtime when calling grail_pull_mtdev(). In practise, grail_gesture may be executed with a test file. 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

Remove pointer emulation

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

With the assumption that X will be handle to handle the gesture cases correctly, remove the pointer emulation 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

Prepare for queued event handling

2011-01-02T11:38:26+00:00

The current grail operates via callbacks. In order to make grail work as a pipe, where input and output can be controlled externally, add the missing event queue for gestures, and align the code to simplify a switch. Signed-off-by: Henrik Rydberg

Use a unified pointer emulation model

2010-11-17T16:22:11+00:00

The existing kernel MT devices together use a handful of different pointer emulation strategies, each with its own subtlety. This creates a problem for grail, which needs to rebuild pointer emulation during gesture recognition; relying on the correct pointer information to be available at the right time becomes almost impossible. This patch implements a common pointer emulation model for grail, following a strategy recently discussed on LKML. This resolves the problems stemming from different emulation strategies, and results in a common pointer emulation experience for all devices. Signed-off-by: Henrik Rydberg

Split pointer status and report status

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

Separate out reporting of the touch state, such that reporting can be deferred. Does not introduce any logic changes. Signed-off-by: Henrik Rydberg
