Abstract: The invention relates to a method to generate computer instructions to control a representation of one or more objects, said representation being defined at least by attributes of said one or more objects, said method comprising: representing, in a graphical form, a source attribute of an object, possible values of the source attribute and one or more target attributes of said one or more objects; allowing a user to select a subset of the possible values of the source attribute; allowing a user to define a rule of transformation of the subset of the possible values of said source attribute into values of target attributes of said one or more objects; generating computer instructions configured to cause a processor to execute the rule of transformation.

Abstract: The invention relates to methods for handling user-level events for programming an application. The methods aim at providing the designer of an application the ability to use easily understandable user-level events rather than low-level, often platform dependant input events, whose use generally requires important programming skills. It also aims at optimizing the generation of user-level events, by improving the detection of events and detecting only a subset of possible user-level events depending on the context of the application.

Abstract: The invention relates to a designer computing device to generate an application, and a user computing device to execute the application. The designer computing device executes decision rules for determining the type of properties and performing a selection of properties of interest of a class to render the development of the application by a designer easier. Indeed, this allows a designer choosing the properties of an object to display among pre-selected properties of interest. Furthermore, a designer computing device of the invention is able to automatically generate a layout of the application, based on the previously selected properties.

Abstract: The present invention extends to methods, systems, and computer program products for processing multi-touch inputs. It provides a method for continuous recognition of multi-touch gestures performed by one or more users on at least one multi-touch input device. The invention in one aspect allows users to start interacting with one multi-gesture and subsequently perform any other multi-touch gestures, if they want it, without needing to lift all their fingers off the multi-touch input device between each multi-touch gesture.
