Javelin:an access and manipulation interface for large displays

We describe a user interface and interaction technique,named'Javelin',designed for large display environments.It provides quick access to random screen regions and manipulation methods for screen widgets which are difficult or impossible to reach.It consists of a dynamic global thumbnail,a touchpad widget that drives the screen cursor,and a teleport widget in which interactions are transferred to its target screen region.Javelin can be easily integrated into many programs to optimize their interaction performance in large screens.The experiment and user study show that Javelin can extend user access field and enhance widget manipulation in large displays.

跨平台Java多媒体显示系统创建研究

随着LED大屏及等离子大屏技术的成熟,大屏幕多媒体显示在各种场合被越来越多地使用。虽然已经有很多大屏显示系统被开发,但现时并没有太多使用Java开发的LED大屏多媒体播放系统,它们一般都存在无法跨平台使用的问题。简介了一个使用Java开发的具有跨平台性能的多媒体播放系统,图示了整个系统的基本构架;并对其中的一些关键技术,如:屏幕分割、分层显示、系统对事件监听的处理、文字处理框、数据库连接及同步、表格显示等进行了阐述。
