A method of creating a workflow on a smart device, comprising: presenting to a user for selection a plurality of input devices, each representing a data input mechanism of said smart device; receiving from the user a selection of one or more of said input devices; presenting to the user for selection a plurality of action devices, each representing a possible action to be taken by the smart device; receiving from the user a selection of one or more of said action devices; wherein each input device has one or more input device outputs, and wherein each action device has one or more action device inputs, and wherein the method further comprises forming one or more input-action associations each comprising a selected input device output associated with a selected action device input. The software provides a new system and method for operating a computer, allowing the user to create workflows linking several different inputs and actions, while avoiding or reducing the need to switch between different applications and different contexts. This results in significant improvements in efficiency and reliability during operation and allows specific workflows to be generated without the need for a skilled programmer. Combinations and sequences of input-action associations can also be generated for enhanced workflow creation.
