    Abstract: 以3D互動式電腦繪圖的方式，在網際網路上提供資
    訊已日趨普遍，但現今大部分的網路虛擬實境系
    統，對一般以2D滑鼠操控電腦的使用者而言，仍不
    十分方便使用。改進此類系統的方式之一，在於為
    使用者於瀏覽虛擬環境時提供一些導引。在本文
    中，我們提出一個軟體系統，能於網路虛擬環境
    中，自動產生個人化的導覽路線。此一已實做完成
    的軟體，整合了機器人學中的運動計畫演算法，及
    網路虛擬實境規格的最新發展（例如VRML2.0）。
    使用者只需以滑鼠點選所欲前往的位置及參觀模
    式，此系統便能自動計算出參觀路徑，並於網路虛
    擬實境系統中引導使用者前往瀏覽這些參觀點。實
    驗結果是以本系大樓3D模型為例做展示。我們預期
    此研究結果可被用於各博物館和國家公園的導覽系
    統中，為當地或遠端使用者提供新的瀏覽協助。
    Interactive 3D graphics is becoming a popular way of
    publishing information on the Internet. However, most
    networked VR systems today are still not very intuitive
    to use, especially for a novice user equipped with a
    regular PC and a 2D mouse. One way to improve such
    systems is by providing users with some guidance during
    the navigation of a virtual environment. In this paper,
    we present a software system1 capable of generating
    customizable guided tours for a networked virtual
    environment. The implemented system incorporates motion
    planning algorithms in Robotics into the latest development
    of network-based virtual reality standards
    such as VRML 2.0. A user can simply click on the locations
    they wish to visit and select a visiting sequence,
    and the system will automatically generate a tour plan
    and guide the user walk through the desired locations.
    Experimental results are presented using a 3D model of
    our departmental building. We expect the result of this
    research to be used as new navigation assistance to
    local or remote visitors of docentry systems located in
    museums or national parks.
