This document proposes Pervasive Maps, an interface that allows users to create digital models of pervasive environments. It describes the Pervasive Maps architecture, which includes a host, client, and editor. The architecture allows users to model an environment by defining places, sights, and resources, and connecting those elements with additional information like photos and annotations. It then explores how users can navigate the modeled environment through application-based, resource-based, and augmented reality interfaces. An initial user study found the concept appreciated but identified room for improving the usability of the modeling tool.

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.
