Abstract: A method for generating an interactions explorer for a user interface prototype comprising detecting one or more prototyping actions while a user creates a user interface prototype, adding the one or more prototyping actions to an interaction hierarchy and generating an interactive visual depiction of the interaction hierarchy.

Abstract: A computer implemented method and apparatus for reproducing an input curve on a mobile device comprising detecting the input curve, sampling the input curve into a discrete set of vertices, performing a normalized dot product of an edge leading into each one of the discrete set of vertices and a tangent to an edge leading from each one of the discrete set of vertices, setting one or more spline stiffness parameter based on the normalized dot product corresponding to each vertex; and converting the sampled input curve into one or more spline patch with the set spline stiffness parameter corresponding to each vertex.

Abstract: A method and apparatus for interpreting multi-touch events on a computing device comprising creating a reference coordinate system using first two touch points A and B on the device, creating a modified coordinate system using second two touch points C and D on the device, determining a reference origin point (O) for the reference coordinate system where a first angle is formed by the points AOB as a right angle and determining a modified origin point (O?) for the modified coordinate system where a second angle is formed by points CO?D as a right angle; and calculating a transformation matrix T between the reference coordinate system and the modified coordinate system.

Abstract: A computer implemented method and system for accessing interface design elements via a wireframe mock-up. The method comprises accessing element information describing one or more design elements, determining a location for one or more element links to be placed on a wireframe mock-up, populating the wireframe mock-up with the one or more element links, and providing the populated wireframe mock-up as an interface to access one or more design elements contained within the design element repository. The location is determined from the element information and the element link is placed in the determined location.

Abstract: A method and system for indexing design elements. The method, when performed by a special purpose computer executing a design repository application, comprises creating one or more metadata entries, linking the metadata entries to one or more design elements, and providing an interface to access the design elements. The metadata entries comprise data describing the design elements located within a design repository. The interface displays the design elements in accordance with their associated metadata.
