Application Of Multi-Touch Gestures In Digital Interface Of Complex System

With the universal application of multi-touch devices, the acceptance of multi-touch gesture is much higher. If multi-touch gestures are integrated into the digital interface, especially those with the features of large amount of information, information nodes and information interaction, not only the natural and efficient feature of multi-touch gestures can be shown, but also the operating efficiency can be increased and the user experience can be optimized.This paper studies the two aspects of multi-touch gesture:digital interface of complex system based on multi-touch gesture and the design of multi-touch gesture in the digital interface of complex system. In digital interface part, the influence factors of the digital interface and multi-touch mode in complex system are analyzed, and the advantages of the multi-touch interface in the user’s cognitive process are described. In multi-touch gesture design part, the differences of input features between multi-touch gesture and traditional mouse are analyzed, the interaction of multi-touch gesture and the application of multi-touch gesture in digital interface are summarized, the basic principles and methods of multi-touch gesture design are carried out.In the fourth chapter, a multi-touch gesture library is designed based on the principle of digital interface design and multi-touch gesture design, to support the map situation, deal with emergency and system task. Finally, the operation efficiency of multi-touch gesture and mouse in multiple tasks of digital interface is evaluated by means of eye tracking experiments, and the advantages and disadvantages of gesture operation and mouse operation are analyzed. The results provide basis to the design methods and provide guidance to multi-touch gesture design.
