Introduction• Devices are different• Various services and situations
call for different devices• Services need to present
different user interfaces• How to create tailored user
interfaces without multiplying development work?
SWEDISH INSTITUTE OF COMPUTER SCIENCE
System Requirements• Abstractions that designers can
use to create a device independent design
• Means to exploit the different capabilities of devices
• Means to control the presentation of the user interface

The Ubiquitous Interactor
Service Interaction Engine
User Interface
Interaction Acts

User InterfaceInteraction Acts
Customization Form
Interaction Acts• Input, output, select, modify,
create, destroy, start, and stop• Contain no presentation
information• Device independent• XML encoded

Customization Form
Customization Forms• Contains optional service and device
specific presentation information• Can be developed separately from
services• New customization forms do not
generate changes in the service logic

What I want to do
SWEDISH INSTITUTE OF COMPUTER SCIENCE
End-User Studies• How do users percieve the
concept of services with multiple user interfaces
• How do users handle device adapted user interfaces
SWEDISH INSTITUTE OF COMPUTER SCIENCE
Pilot study of multiple user interfaces
• Paper prototyping worked fine, but better instructions are needed
• Context and scenarios would help• Users need help to think of different
GUIs
SWEDISH INSTITUTE OF COMPUTER SCIENCE
Device adapted UIs• Comparison with no adaptation (web
pages, remote desktop) and separate design
• Possible parameters– Understanding– Preferences – Performance
SWEDISH INSTITUTE OF COMPUTER SCIENCE
Summary• I have technology for developing
services with multiple user interfaces• Now I want to take it to end-users
– Concept– User interfaces
