NordiCHI’14 Workshop – Beyond the Switch: Explicit and Implicit Interaction with Light

October 26, 2014: Helsinki, Finland
in conjunction with NordiCHI’14 (
Accepted papers



The introduction of connected lighting, which can be integrated with sensors and other devices, is opening up new possibilities for creating responsive and intelligent environments. The role of lighting in such systems goes far beyond functional illumination. Extensive lighting networks are established in which digitally controllable LED light sources enable almost limitless lighting output possibilities, such as dynamic and coloured light. Despite this potential, the current approach for controlling such systems is to use traditional light switches and controllers or to replace these with a more sophisticated smartphone-based control. We however, believe that in many situations the user interaction can become intelligent and sensitive to the context so it is responsive to the people and their needs in the environment. In particular, we are interested in defining a balance between automatic/intelligent lighting control (e.g. light level adapting in the office) and explicit user control (e.g. using a dedicated control device). Aspects such as feedback, feed forward, user understanding of system behavior, physical form of the UI and the role of lighting as a part of smart environments will all need to be considered when designing new spaces. The focus of this workshop is to bring together a community of researchers, designers and technologists to explore new ways of interacting with light when it becomes contextually aware and part of the environment.

The main goals of the workshop are:

–      Explore and define novel ways of interacting with light in different indoor contexts
–      Identify the optimum balance between internal system control and user control, as the complexity and the flexibility of new light systems will require at least a partial automation
–      Explore the impact of connectivity between multiple systems and other ecosystems of a connected lifestyle on lighting and vice versa


Topics of Interest

–          Interaction design for lighting systems

–          Adaptation of existing UI paradigms to lighting systems

–          Lighting as integral part of the smart environments (e.g. smart home)

–          User studies of interactions that are or can be applied to interactive lighting systems

–          Smart lighting systems

We invite researchers and designers interested in exploring user interaction for new forms of lighting systems.

Workshop structure

The first part of the workshop (the morning) will be dedicated to the introduction of the emerging forms of lighting and presentations of the individual attendees. The afternoon will be dedicated to a hands-on interactive session with discussions and prototyping in groups, for which the topics will be formulated based on the initial set of workshop questions.
