Outline
• Introduction• Background and Related Work• Pervasive Maps Architecture• Modeling the Environment• Exploring the Environment• Case Study• Conclusions
Introduction
• Pervasive Environments– 現代化的便利服務– 展場導覽
•如何找到這些服務設備、整合所有資源– 考慮到環境陌生者的使用權
•找到服務設備,但使用者不會使用。– 使用者介面設計
Middleware Infrastructures and Interaction tools
• UPnP (通用隨插即用 ) – 網路協定– Only return limited information
about discovered entities.
• Philips Pronto– 控制多個房間的整合式使用者介面 影片
– Merely deal with IR/RF
Visualizing a Pervasive Environment
• NaviCam• Digiscope• U-Photo• PECo
Pervasive Maps
•研究靈感來自電腦的「檔案總管」– 提出一用在mobile上的介面
•讓使用者可以建立自己的環境模型– 加入相片、註解、方向等資訊
•人機介面– Service-oriented VS. Application-
oriented– Web interface
Pervasive Maps Architecture
• PM host:– PM gateway
– Serves a dynamic Web interface
• PM client:– Assists end-users in accessing a PM
environment
– Can be extended with plugins.
• PM editor:– Design and configuration tool for the PM host.
Modeling the Environment
Resource
• A resources
– Mobile interaction devices
• B resources
– Everyday, often stationary computer augmented resources.
• C resources
– Invisibly embeded in the environment but can be discovered by application
• D resources
– Correspond to physical objects without computing platform that refer to other resources or applicatoins.
Modeling Process
• Define places– 組織各區域的相對位置
– 加入大小、方位等空間資訊
• Define sights– 由不同區域的照片組成一景物
• Define resources– 定義、連結每個可以使用的資源
• Connect places, sights and resources– 照片重疊的問題
• Z排序
– Relative distance calculate
Application-based navigation
Resource-based navigation(List)
Resource-based navigation(Map)
Augmented Reality
• Locate oneself in an unfamiliar environment
• Access the digital dimension of a resource.
• Create a dedicated 'start menu' in the real world composed of tags.

Conclusions
• A first user study point out that appreciation factor of Pervasive Maps is high.
• PM editor still lacks a satisfactory stage of usability.
• To improve the modeling tool, – users suggested to include a step-
by-step wizard for creating a digital version of their environment.
