基于多通道界面的控制中心大屏幕人机界面模型

摘要

Large screen display systems have been widely in power system control centers. As large screens are substantially different from small -sized control panels, and the human computer interaction system of the latter can not meet the requirement of the former, thus intensive special studies should be carried out for the interaction. This paper designs an HCI system for large screen displays based on MMI, which is composed of multimodal information acquisition, multimodal information recognition, information integration, and multimodal information output. At the input. the system adopts a multimodal integration model which mainly adopts phonetic information supplemented with gestures, and this pattern is more natural and practicable.Visualization and Text-To-Speech (TTS) are used in the output to display system information as graphics and voices which are easier for operators to understand.%大屏幕显示系统已在电力系统各类控制中心被广泛使用.鉴于大屏幕与控制台之间截然不同的显示特点,简单套用后者的人机界面并不合适,有必要对大屏幕人机界面进行专门的研究.设计了适用于控制中心的新型大屏幕人机界面.该系统以多通道界面为基础,由多通道信息采集、多通道信息识别、信息整合、多通道信息输出等模块组成.在输入端,该系统采用以语音为主、手势为辅的多通道整合模式,较之鼠标、键盘更为自然和实用;输出端则充分利用可视化及语音合成技术,以调度员更易理解和接受的图形、语音等多媒体形式展现系统信息.
