To adapt for the requirement of user interface development in multi-device environment and address the problem that current UIDL has,this paper designs and implements a lightweight multi-device user interface description language MDUIDL.This language is divided into abstract interface description language, specific interface description language,event description language and device description language, which respectively describe the different sides of user interface of multi-device application system.By a case study, this paper shows that the language has a good ability of description interface and supports for multi-device environment,and it is so simple that one can learn and use easily.
