In the pervasive computing environments, the diversity of the device interfaces leads to the phenomenon that interactive semantics communication and presentation is getting increasingly complex on various devices, resulting in difficulties in the interoperability of heterogeneous devices. From the point of users' view, interactive semantics is the information content which can be seen in the interfaces and can be controlled by the users. The invariability of the information contents makes it possible to intemperate between heterogeneous devices. Based on XML, a deviceindependent interactive semantics transmission protocol —GISTP, is designed and implemented, which is used to communicate and represent the information content in the main window of the interface, and the availability and effectivity of the protocol are illustrated by a case study which implements GISTP interpreters on different devices.%在普适环境下,设备界面的多样性导致交互语义在不同设备上的通信和表示日趋复杂,造成异构设备之间互操作的困难.从用户观点,交互语义即能在界面上看到并能控制信息内容.信息内容所具有的不变特征使异构设备之间的互操作成为可能.基于XML,设计并实现一个与设备无关的交互语义传输协议GISTP,用于界面主窗口内的信息内容通信与表示,并通过实现不同设备的GISTP解释器说明该协议的可行性和有效性.
