未來的智慧聯網(IoT)將生活中各種裝置都變成網路服務，而智慧聯網瀏覽器(IoT Browser)是一個可以讓使用者透過手機等裝置簡單的瀏覽各種智慧聯網機器並與之互動，將大幅簡化人類使用這些智慧聯網服務的操作，對人類生活及使用服務的方式產生很大的革新。瀏覽智慧聯網相較於傳統瀏覽網頁，有著許多獨特的特性，包含：(1)資料來自各種分散的異質裝置、(2)時空(spatial-temporal)資訊的關鍵性、(3)虛擬世界與真實世界的整合及(4)全新的互動方式。此外，考慮智慧聯網瀏覽的方式及智慧聯網的未來發展，本文指出智慧聯網服務整合的頻繁及資源重複利用的必要性。針對這些特性需求，我們提出智慧聯網瀏覽系統來提供適合瀏覽智慧物件的環境，系統的核心是設計中介層(Middleware)來提供語意及情境感知機制，藉此達到互操作性(Interoperability)、裝置服務自動發現(以時空為基礎)、資訊自動管理及資源重複使用等。系統實作中，使用者可利用手機任意與各種裝置、物件互動，並透過此系統的語意技術，讓各種智慧聯網服務的知識(knowledge)互相分享，以達到以時空為基礎的瀏覽、資源重複利用以及情境推理，完整發揮瀏覽器潛能。

IoT browser is a useful tool for the Internet of Things (IoT), which provides a novel way for people to interact with daily life objects through the internet. Comparing with traditional web browsing environment, IoT browsing environment has some unique features such as the way of interacting with the objects, the importance of spatial-temporal information of objects, and the necessity of resource reuse. Considering the distinctive features of IoT browsing, a new system architecture is needed to fulfil the requirements of IoT browsing environment. In this paper, we propose an IoT browsing system with a semantic-based context-aware middleware for IoT browser. The system adopts a service-oriented architecture and provides device interoperability, resource reusability and spatial-temporal-awareness. The basic functions of the middleware are distributed in local gateways and the cloud. Furthermore, context-awareness is introduced to make the browsing more intuitive. We develop a prototype of the proposed system and demonstrate the applicability of the system in a browsing scenario. The prototype shows that with the help of the IoT browsing system, heterogeneous devices can cooperate with each other to provide IoT services in accordance with context inference results. In addition, each device can be reused by multiple services with minimum human supervision to reduce hardware and deployment costs.
