Transcript

  • 1. Pervasive Maps: Explore and Interact with Pervasive Environments Geert Vanderhulst Kris Luyten Karin Coninx Hasselt University - transnationale Universiteit Limburg Expertise Centre for Digital Media Wetenschapspark 2, 3590 Diepenbeek, Belgium
  • 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
  • 7. 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.
  • 8. Modeling the Environment
  • 9. 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.
  • 10. 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
  • 11. Application-based navigation
  • 12. Resource-based navigation(List)
  • 13. Resource-based navigation(Map)
  • 14. 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.
  • 15. 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
  • 16. Likert scale 1~5
  • 17. 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.
