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.
