2. Outline
• Introduction
• Background and Related Work
• Pervasive Maps Architecture
• Modeling the Environment
• Exploring the Environment
• Case Study
• Conclusions

3. 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

4. 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

5. Visualizing a Pervasive
Environment
• NaviCam
• Digiscope
• U-Photo
• PECo

6. 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

8. 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.

9. Modeling the Environment

10. 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.

11. 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

12. Application-based
navigation

13. Resource-based
navigation(List)

14. Resource-based
navigation(Map)

15. 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.

16. Museum environment Digital score
1. 查詢博物館的背景音樂
2. 連結到 wiki 看資料介紹

17. Likert scale 1~5

18. 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.
