Need a Light? - Workshop on Mobile Light Information Systems
August 27, 2013, Munich, Germany
Submission deadline: May 10, 2013
Held in conjunction with 15th International Conference on 
Human-Computer Interaction with Mobile Devices and 
Services (MobileHCI 2013)

Light is one modality of conveying information to users. One basic example 
is a traffic light that uses well defined light icons (e.g. green light vs 
red or yellow). With proliferation of LED based lighting we see more and 
more examples of light displays either used for decoration or for 
conveying information on a smaller scale both outdoor and indoor. The main 
distinction from conventional displays is that light displays usually use 
high power LED lighting, have a relatively low resolution, and do not 
always consist of a well aligned light pixels. Lately, we further see the 
emergence of mobile/wearable light displays such as the “Damage” bracelet 
or “AmbiGlasses”.
Light displays can provide information continuously and unobtrusively. 
They can designed to be be perceived at a glance, do not require focused 
visual attention and ideally are aesthetically pleasing. On the other 
hand, they can be designed to be attention demanding and alerting.
At the same time we see an appearance of connected lighting systems that 
can be controlled from anywhere using internet connected devices such as 
smartphones. While it might not be new approach for the office domain it’s 
only now started to appear in the home domain. Similarly, we see examples 
when connectivity and interactivity can be used for making urban 
decorative lighting more dynamic and engaging by allowing people to 
control some aspects of it.
With this workshop, we want to address the challenges of conveying 
information with light displays as well as control of such displays in the 
mobile context. We invite work on mobile light displays and the human 
interaction with them as well as contributions focused on mobile 
interaction with (not necessarily mobile) light displays.

Looking at the mobile context, the amount and type of information that can 
be displayed by light displays is key since:
- Visibility may be impaired when an ambient light display is being 
carried around by it’s user.
- Portability may be an issue in itself.
- Privacy issues need to be addressed, as light displays need to be 
visible in order to work. On the other hand, information is not explicit, 
therefore ambient light may well be suited for private/public information 
- Social acceptability needs to be considered when designing interfaces 
for the mobile context.

We invite concept papers as well as reports on research projects to this 
workshop. We envision participants from both industry and academia who 
have an interest and/or experience in the following themes:
- Design patterns and methods for mobile light displays
- Prototyping techniques
- Privacy and social acceptance of light in the mobile context
- Infrastructures, platforms, and tools for creating and deploying mobile 
light displays
- Evaluation methodologies in the lab and in the "wild"
- Applications and services
- Controlling light displays with mobile devices

Expected Outcome
The aim of this workshop is to bring together people who are active in the 
area of lighting HCI research. The expected outcome is an overview of the 
recent challenges of mobile deployments or interaction and potential ways 
to overcome them. We aim to generate insights in new questions that 
present themselves when it comes to doing research in this dynamic 
landscape of mobile light displays as well as mobile interaction with 
light. Participants are expected to discuss, share, and take away 
beneficial insights, strategies, tips and tricks in dealing with issues 
such as visibility, privacy, acceptability and control. This workshop 
website will feature all accepted papers and a brief summary of the 

Submission Details
"Need a Light?" is intended to be a full-day workshop. Participants are 
expected to submit a paper of 2 to 4 pages via email by May 10th 2013. All 
submissions must follow the MobileHCI 2013 archive format. General terms 
as well as the ACM classification should be removed. The copyright 
statement should state that the copyright remains at the authors of the 
Participants will be selected on the basis of the quality of their 
position paper in a peer-review process by the organising committee. 
Successful submissions will have the potential to raise discussion, 
provide insights for other attendees, and illustrate open challenges and 
potential solutions. The organizers will select the best submission which 
may appear in the International Journal for Mobile HCI with an extended 
Authors of accepted submissions will be notified by June 10th 2013. At 
least one author of each accepted paper needs to register for the 
conference and the workshop itself. Each accepted paper must be presented 
at the workshop, whereby each talk should be between 5 to 10 minutes and 
should inspire a brief corresponding discussion. Accepted papers will be 
distributed amongst the participants prior to the workshop and will be 
published on the workshop website.

Submission Instructions
All submissions will be handled via Email. The documents should be 
submitted in PDF format to [log in to unmask] If your submission comes 
with supplemental materials, e.g., videos, then everything should be 
packed in one ZIP file. If you experience any problems, please email the 
workshop's organizers at the abovementioned address.
