Abstract: Providing expert help to a user comprises providing an application for execution on a mobile device of the user associated with an entity. A computer receives entity rules from the entity, the entity rules include a definition of how communication channels are created. The entity rules are stored in a rules database in association with the user. A help request initiated by the user through the application program and sent by the mobile device, the help request comprising a current context of the user comprising a user ID and a task ID of a current task. Using the entity rules, the current context is transformed into search parameters that are used to search a knowledge repository for experts having profiles that match the current context of the user. The entity rules are used to automatically create a communication channel between the user and the experts matching the current context.

Abstract: Symbian OS applications assume a directory structure that has been defined by Symbian and defines a standard set of directories starting from the root of a drive. This is not compatible with the Memory Stick standard. The method presented provides applications with a drive that appears to be a standard Symbian drive but actually transparently maps to a safe area on the Memory Stick. It is also possible to access special Memory Stick defined root directories (e.g. for pictures and audio) and to map these directories to standard Symbian-style directories.

Abstract: The control areas (e.g. keys and buttons) in a GUI of a touch screen based computing device represented in a color mask stored on the device; the color mask has regions exactly corresponding in shape and size to each of the control keys or buttons; each region is completely filled with a unique color. In use, when a X,Y co-ordinate pair for a particular contact/touch point is generated, it is straightforward and very fast to extract the pixel color that is present at the same X,Y co-ordinates of the color mask. It is also then very fast and straightforward to establish the control area associated with that color by matching the pixel color to a table that stores each control area together with its associated color in the color mask.
