Research on command space cognitive concept model and multi-fingers touch interactive method

Abstract

Natural and efficient HCI technology has been rapidly developing. However, there is always cognitive 'gap' between HCI and application space. Taking command post of the future as main researching object, the paper explores how to properly combine information modeling with HCI technology and realize the proper abstraction, description and mapping of command space element, according to an order from 'top' to 'down': Cognition level, Operation level, Control level and Device level. Starting with conceptual model, command space is modeled on the cognition level. Next, basic methodology are brought forward, which combine command space cognitive concept and map them to operation and control, based on multi-fingers/two-handed touch interaction. This paper focuses on the modeling method of user multi-fingers touch operation model, and the control method from user operation model to multi-fingers touch HCI, to realize conversation between user and device in command space, to improve efficiency of commanding operation and decision-making. The research above can provide theory and method for constructing command and decision-making space of the future and has forerunner effect on multi-modal HCI system. © Springer-Verlag Berlin Heidelberg 2007.
