可在终端上执行的各种应用程序可使用至少一个共用的物理用户接口设备，诸如触敏表面。触敏表面的一种或多种功能以及显示在终端上的相应信息可从一种应用程序调整和/或变化至下一种应用程序和/或在相应应用程序内被调整和/或变化。这样，终端的共用物理架构(诸如触敏表面)可利用对于用户而言直观清楚的用户界面来支持各种应用程序。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关的硬件来完成，所述的程序可存储于一计算机可读取存储介质中，该程序在执行时，可包括如上述各方法的实施例的流程。其中，所述的存储介质可为磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)或随机存储记忆体(Random Access Memory，RAM)等。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
