From 3b837806891de6cf77d4d74d04567e7e68c82fc0 Mon Sep 17 00:00:00 2001 From: Henrik Rydberg Date: Tue, 13 Jul 2010 11:26:46 +0200 Subject: Gesture Recognition And Instantiation Library (grail) The aim of this first commit is to get down to hard testing of concepts, and the library currently has two test programs, touch and grail, which can be run on commandline. Touch tests the touch interface, and grail tests the gesture interface. Expect thinking errors and some glitches. Other than that, the code runs fine.
