CID > Interaction forms    

Interaction forms is an area where we propose and study new forms of interacting with computers. Both in the way we know computers today and what the new possibilities are when the computing power moves into the physical world. Interacting with things is a normal activity for everybody. And there is a long experience of designing and reflecting over how we people use artefacts of all kinds.
We have a spectrum of projects, from basic research to reuse of existing technologies in new contexts.

The current convergence of interactive digital systems, networks and mobile devices is transforming the ways that we carry out our everyday life, e.g. how we entertain ourselves, work, shop and converse. In contrast to the existing visions of ubiquitous computing, our vision is to recognise from the outset the variable levels of digital richness available in the world and to construct both design techniques and supporting infrastructures that recognise this variability as a fundamental feature.
The underpinning model we have is of an electronic landscape constructed of inter-connected digital locales often separated by digitally sparse regions.

This work is about investigating new techniques for giving blind users better access to graphical user interfaces using sound. Experience gained from studying auditory direct manipulation in both a single-user and a collaborative setting is developed further to investigate collaboration between blind and sighted users.

With the project "Silent Sound Sculpture" we want to achieve silent zones in noisy environments. The purpose is artistic, to "visualise" our noisy environment to a wide audience and open the debate on this issue, as well as a practical contribution to the development of a better sonic environment. A condition for realising the silent sound sculpture is broad research and development work including new methods and technical solutions on active sound control.

This project, Designing Interactive, Intergenerational Interfaces for Living Together, is part of the Disappearing computer initiative within FET (Future Emerging Technologies). Communication over generations is studied in families in Sweden and in France. Possible IT support in the form of communication surfaces will be prototyped and studied together with the families. Research partners are University Paris Sud, INRIA in Paris and (indirectly) University of Maryland.

The project is collaboration between CID and CVAP at NADA, KTH. It studies the
use of hand gestures for interaction. The approach is based on recognition of gestures by computer vision. The main scenario is ubiquitous, everyday computing, with a focus on developing interfaces for people with special needs.
The scope is limited to Multimodal user interfaces. Gestures need not be natural
gestures: they could be developed for the situation, or based on some standard sign language. Conversational interfaces, automatic recognition of natural, human gesture falls outside of the scope of the project. The current focus is on developing command sets for interaction. As a starting point remote control of electronic appliances in a home environment, such as TV sets and DVD players has been chosen.

A project on Home, Health and Product Design
The focus of this work is on unhealth issues and the design of IT products in the home. What is the relation between design and health? What are the aesthetical issues in design for Home health care? What is “healthy” and “unhealthy” in the home?
It is particularly important today to understand those issues when stress and sick leaves are increasing and we are facing large demographic problems.
The methods are multiples ranging from surveys, interviews and user studies to
design concepts, developing products and finally to evaluate them. The work attempts to look at and create a basis for understanding design as both a process and an aesthetic practice within the HCI context.
