Call for participation:

Workshop on User Interaction Techniques for Future Lighting Systems

September 5, 2011: Lisbon, Portugal
in conjunction with Interact  (

Deadline for submissions is June 10, 2011.

Call for Papers

The Light Emitting Diode (LED) has caused a profound change within the lighting industry. This is due in part to the LED’s key properties of being physically small, highly efficient, digitally controlled and soon, very cheap to manufacture. Being physically small the LED can be positioned or embedded into luminaires, materials and even into the very fabric of a building or environment.  
The price to pay for all this functionality and flexibility is complexity.  In the past, the light bulb was controlled using a single switch; on and off. LED-based lighting systems can easily consist of hundreds separate light sources, with each source having many individually controllable parameters including colour, intensity, and saturation. With this high complexity, end-users cannot be expected to fully control all aspects of the lighting system. One direction that is being explored is to enrich lighting systems with sensor networks that will enable automatic (smart) lighting control that is based on contextual information, where the very basic example of such a system is presence detection in the office environment. However in many situations, such as setting up an atmospheric light, an explicit user interaction will still be required. Moreover, as functionality and complexity of light systems grow, the mapping between the sensor data and the desired light outcome will become fuzzy and will require an explicit user interaction for fine tuning the outcome or for adjusting the mapping between sensor input and light output. Thirdly, explicit interaction can be desired to allow users to feel in control while interacting with intelligent lighting systems. The light switch therefore in many situations will need to be replaced by novel forms of interactions that offer richer interaction possibilities such as tangible, multi-touch, or gesture-based user interfaces. As proliferation of LED light continues, it becomes more important to go beyond scattered design efforts and systematically study user interaction with emerging lighting systems. The goal of this workshop is to take the first steps in this direction.  
The focus of this workshop is on formulating key research challenges for user interaction with future lighting systems, creating initial design guidelines, and proposing novel interaction techniques for these systems. The main goals of the workshop are:
•	Make a first step toward expanding the design space of interactive technologies to include new forms of decorative, ambient, and task lighting.
•	Identify key challenges of UI for controlling new forms of lighting systems.
•	Establish a link with existing interaction paradigms that can be (re-)used for control of future lighting systems. 
During the workshop, we will address and discuss the following questions: 
•	What design opportunities for interactive technology exist in the context of the new forms of lighting?
•	What forms and types of (existing) interaction are suited for emerging lighting systems (in particular tangible, gesture and multi-display interaction techniques)?
•	What forms of interaction are best suited for a global control (e.g. atmosphere) and what for a point control (e.g. task lighting)?
•	How to balance between explicit user control and internal system control?
•	How to use a lighting infrastructure as ambient displays and how to combine it with its primary function i.e. illumination?
•	What is the impact of the proposed interaction techniques for complex lighting systems in other domains? What is the generalizability of these techniques?

Topics of Interest

Topics include:
•	Interaction design for lighting control
•	 Adaptation of existing UIs to a lighting control
•	User studies of interactions that are or can be applied to lighting control
•	smart lighting systems
•	Light perception

We invite researchers and practitioners 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 discussions in groups, where the topics for discussions will be formulated based on the initial set of the workshop questions. The poster(s) describing identified challenges and opportunities for interaction technologies around light control will be created during the last session.

Workshop outcome

•       A map of the most relevant issues in designing interactions for emerging lighting systems
•       Networking with other researchers and practitioners in the newly forming area of user interaction techniques for future lighting systems
•       Further publication possible, depending on the submissions received
