Abstract: Techniques for authenticating a user based on hand features includes receiving sensor data of a scene that includes hands, extracting features for at least one of the hands, and determining a first identity associated with the at least one hand based on the extracted features. The user identity may be associated with authentication information such that when a system detects a gesture by the hands, the authentication information is assessed prior to performing an action associated with the gesture. Authenticated users may be used for determining authorized activity for performing an action associated with a gesture, and may be used for collaborative activity among users.

Abstract: The invention is directed to a method which derives from metadata definitions the allowable values for a method argument, where the allowable values are a subset or a restricted set of values from a defined range of values for that type of method argument. The subset of allowable values is then converted into a fragment of source code that can be used to initialize the argument variable with one of the allowable values when the method is invoked. The fragment of source code is inserted into the source code for that method argument using an editor tool. A system for implementing the method may comprise an integrated development environment (IDE) program.

Abstract: A method, apparatus and computer-readable medium for improved correlation between source code in a source code view pane and a corresponding control in a graph view pane in an Integrated Development Environment (IDE) is presented. In one embodiment, the method includes the steps of receiving, from a user of a source code view pane, an entered name of a type of control that is to be modified in an Integrated Development Environment (IDE), wherein the control is displayed in a graph view pane of a Graphical User Interface (GUI); in response to a hyperbutton being activated, displaying a mini-GUI in the source code view pane, wherein the mini-GUI displays all controls that have the entered name as part of their source code; and in response to a selection of a selected control in the mini-GUI, dismissing the mini-GUI and pasting, in the source code view pane, a name of an actual source code object that, when executed, displays the selected control in the GUI.

Abstract: Methods, systems and computer program products are provided for displaying a plurality of visual elements associated with a computer program application by defining a sequential tabbing order for the plurality of visual elements and displaying at least one graphical linking element extending between the plurality of visual elements. The graphical linking element represents the sequential tabbing order.
