说明：  提出一种新颖的基于虚拟控件的遥操作救灾机器人系统图形界面设计。控制区被嵌入到图像区，机器人传回的现场图像全 窗口显示。在图像窗口内指定特定区域作为虚拟控件，实现机器人的导航操作。虚拟控件是图像本身的一部分，其控制能力线性可 调。该界面设计将用户的注意力转移降低为零。实验证明该界面设计能够显著提高救灾机器人的导航效率。
(A novel graphic interface design based on virtual controls for the navigation of remotely controlled rescue robots is proposed．The control area is embedded into the image Bl ea．The images transmitted back by robots are displayed in full window．Some of the fields in graphic window are specified as virtual controls acting for navigation operations．Virtual controls，which aFe parts of images，offer linear adjustable con— trol capabilities．The proposed interface design reduces the attention shifting from useis nearly to zero．Experimental results show that the pro— posed interface design enhances the navigation eficiency of rescue robots apparently．)
