In view of the line and surface tactility displayed by the pneumatic nozzle array,a fluid-structure coupled finite element model of the finger skin and nozzle was established.

Based on the analysis of the sound type and sound design methods in the auditory interface,through citing semiotics and semantic into the AUI domain,this article analyzed and compared the similarities and differences of the sound semantics in the UI of handset and IM software,and obtained some valuable conclusions and research ideas.

Auditory User Interface (AUI) is the most useful and compelling one of them.

Study on Au-CdZnTe contact interface deposited by different process;

When the incidence wave is strong enough, the contact interface will separate or slide on local area, which is harmful to the safety of the structure.

Reflection and refraction of an elastic pulse at a frictional contact interface between two anisotropic media is studied theoretically in this paper.
