摘要:

本文描述了一个基于多点触摸技术的GIS (Geography Information System)。该系统利用Rear-DI技术搭建触摸操作平台,通过TUIO (Table-Top User Interfaces Objects)协议在触点追踪模块和GIS模块之间传递触点信息。系统定义了几种常用GIS操作对应的多点触摸手势及其状态转移模型。在此基础上给出了一种基于触点轨迹的手势识别方法。该方法能够将触点轨迹识别成有效的交互手势并通过MapX操作GIS

This paper describes a GIS (Geography Information System) system based on multi-touch technology. The system uses the Rear-DI technology to build touch platform, and transfers touch point data by TUIO (Table-Top User Interfaces Objects) protocol between the tracking module and GIS module. Some multi-touch gestures corresponding to common GIS operation and its state transition model are defined in the system. According to these definitions, a track- based gesture recognition method is given. This method can recognize the trajectory into correct interaction gestures and operate the GIS through MapX.
