Problem
� Spontaneous (unplanned, natural) use of (previously unknown) pervasive services core to ubicomp.
� Network discovery technologies facilitate spontaneous connections.
� Remains difficult for mobile users to identify available services then configure and consume them.

Introduction: Goal
� Trying to help the mobile user to:
1.1. IdentifyIdentify services available in his immediate environment.
2.2. ConsumeConsume the services in a natural, seamlessnatural, seamless manner.

User Interface Concept
� Visual Service Discovery.
� User Interface as a “compass”:
� Identify available services in the immediate environment.
� Gateways: widgets representing the service providers:
� Provides access to the services.

Implementation
� Small Java Swing windows representing the service provider.
� Integrated to the mobile desktop.
� Two interactions modes:
� Drag-and-Drop.
� Click.

Positioning Information
� Wizard of Oz used for user-study.
� Next step: provide the user interface with actual positioning information.
� Working on an extend of the Relate ad-hoc sensor network.

Scenario
� Formative User Study in Munich (LMU):
� 20 users.
� 3 enabled services in a large office.
� 2 devices to interact with the services:
� OQO Handheld
� Paceblade TabletPC
Evaluation

Results
� Formative study only:
� Lacking comparison with other systems (Bluethooth, ICrafter, list view VS gateways, etc.).
� Most cited benefits:
1. No installation, no configuration: saves time.
2. Ease of interaction with the services: drag and drop.
3. Dynamic spatial arrangement of the gateways:
unknown places.
� Suggested a number of UI improvements.
