中文摘要 | Web-based 的學習環境相當的廣泛及多元化,已成為一種隨時隨地的學習方 式。故本研究規劃設計出克服時空障礙限制的“情境感知式悠遊學習系統 (Situation-Aware Ubiquitous Learning System, SAULS)",利用手持式設備,整合 無線與行動式網路進行即時性的多媒體串流服務。此外結合無線感測網路、無線 射頻辨識、客製化服務、位置感知服務、群體廣播、Web-GIS、虛擬實境、決策 支援系統與智慧型代理人等技術,即時性之災區現地資料收集、分析及多媒體展 示,並分析出災害主要成因,及早建立災害防治措施。SAULS 提供個人客製化 之行動學習環境,並輔以生活管理小幫手,讓使用者可以隨時隨地進行有效率之 學習。 |
英文摘要 | Digital learning system based on Internet, symbolizing rich, multiple information, and providing fast and convenient search engine have already been as a useful tool for learning. Using digital learning system, we could build the ubiquitous e-learning environment. This paper proposed a Situation-Aware U-Learning System (SAULS), which is a three-tier system composed of the mobile users, multimedia servers, and model database server. The proposed SAULS adopts the wireless sensor network and 3D Virtual Reality (VR) technology to perceive the environmental change and produce the flood disaster simulation. SAULS provides the real-time multimedia information to react the disaster situation immediately. The communication networks include Internet and 3G/GPRS/GSM mobile networks. To transmit and display the relief maps of location in real-time, we proposed the effective escape path algorithm to predict the corrected direction and transmits the minimum relief maps to users. Mobile user can learn easily and effectively at anytime and anywhere using SAULS, which adopts RFID technology and Life Quality Management Helper (LQMH). The performance evaluation reveals the effectiveness and efficiency of SAULS. |
