The PPD 08 workshop on designing multi-touch interaction techniques for coupled
public and private displays focuses on the research challenges and opportunities
afforded by the combination of touch sensitive small private input displays
coupled with large touch sensitive public displays. Different touch-enabled
devices rely on different types of touches (passive stylus, active stylus,
fingers and tangible objects), the motivating question for this workshop is
how do users switch between these devices and how to facilitate fluid transition
from a collection of multiple displays to a single integrated multi-display

Recent developments have seen the wide spread proliferation of both large shared
displays and small display technologies. In parallel we have seen the emergence
of new classes of device which support both touch or multi touch interaction.
Examples of small touch driven devices include PDAs, Tablets and iPhones and
examples of large interactive surfaces (mutli-touch driven displays) include
the Diamondtouch and Surface Computing. Interactive surfaces offer great
potential for face-to-face work and social interaction and provide natural
ways to directly manipulate virtual objects whereas small devices afford the
individual a personal workspace or "scratch space" to formulate ideas before
bringing them to a wider audience. Advanced visual interfaces can be built
around a combination of both private and public touch driven displays. Such
computer mediated multi-device interaction between local touch-driven displays
and shared public ones presents a number of novel and challenging research

This workshop will specifically focus on the research challenges in designing
touch interaction techniques for the combination of small touch driven private
input displays such as iPhones coupled with large touch driven public displays
such as the Diamondtouch or Microsoft Surface.

Topics of interest include, but are not limited to

* Understanding the design space and identifying factors that influence
user interactions in this space
* The impact of social conventions on the design of suitable interaction
techniques for shared and private displays
* Exploring interaction techniques that facilitate multi-display interfaces
* Personal displays as physical ob jects for the development of interaction
techniques with shared multi-touch displays
* Novel interaction techniques for both private and public multi-touch
devices as part of multi-display environments
* Techniques for supporting input re-direction and distributing information
between displays
* Developing evaluation strategies to cope with the complex nature of
multi-display environments
* Ethnography and user studies on the use of coupled public and private
display environments

We invite contributions from researchers and practioners working in the area of
multi-display environments and horizontal interactive surfaces coupled with
private displays. Interested attendees should submit a short position paper of
less than 4 pages. Based on a peer review of the position papers about 10 to 15
participants will be invited to attend the workshop.
