       Bringing Together Indoor and Outdoor Mobility Solutions:
        Methodological Approaches for Navigation, Localization
                        and Environment Modelling

                    2nd Workshop at the AAL Forum 2014
      Friday 12 September 2014, 9:00-16:00h, Bucharest, Romania

The central aim of this workshop is to bring together researchers, 
industry representatives, and end-users of ICT-based solutions in the 
realm of mobility assistance for Ambient Assisted Living. The primary 
focus will be on relevant AAL-JP projects, particularly from call 4. We 
see a definite plus, if not need, in sharing scientific and technical 
expertise and experiences, and are looking forward to input from 
industry and user organisations regarding overall requirements and 
business perspectives. The workshop will be open to general participation.

ICT-based solutions for increasing the mobility of elderly people in 
activities of daily living are dedicated to help answering two simple 
questions: “Where am I?” and “What is the route to my destination?” 
Whether the assistive system is given by a helpful app running on a 
portable device, or by a robotic device that additionally provides 
physical support: the two central questions address the following topics:

* Route planning and accessibility: Given the actual and the desired 
pose of the user, how do we plan a feasible route that considers bar- 
riers, path conditions, and physical effort, i.e. a path that is 
completely accessible? How do we plan the route such that it accounts 
for certain points of interest, e.g. suggest a detour to the bakery?

* Navigation and interaction design: How to present maps and route 
information to elderly users? Current off-the-shelf solutions don’t 
consider their special requirements, such as diminished vision and 
hearing, but also the cognitive load of map-based user interfaces is 
rather high.  We are also interested in alternative solutions to 
turn-by-turn instructions, which work nicely in street networks, but 
fail for pedestrians in open scene space. Additional modalities, such as 
vibrotactile handlebars, are also promising to improve the user interface.

* Transportation modes and transition: How do we allow for different 
modes of transportation, e.g. as a pedestrian on foot, with a walker, on 
a wheelchair, by public transportation, etc.? How is a seamless 
transition between these achieved?

* Security and orientation: How can we assist users when they get lost, 
the technical assistance fails, there is an emergency or they need 
further orientation (e.g. in case of slight dementia)?

* Seamless indoor and ourdoor positioning: Sensorial equipment like 
Satellite Navigation and inertial sensors are widely available in mobile 
devices today and facilitate outdoor localization up to a certain degree 
of precision. Indoor localization solutions require more sophisticated 
sensorial equipment such as RFID beacons or Computer Vision/LIDAR. How 
do we achieve a smooth transition between indoor and outdoor spaces?

* Environmental representations and maps: We want to discuss available 
map representa­tions suitable for hybrid modelling of indoor and outdoor 
route networks along with relevant impediments, landmarks, and points of 
interests. We will further go into issues of standardization and 
integration of indoor map representations into OSM or comparable 
databases, and sensor-based approaches to obtain building maps.

Desired Contributions
We encourage you to contribute a 15 min presentation to one of the 
sessions listed above. To select the presentations, in case there are 
too many, and to relate them to the above topics, we would like to ask 
you to send us a contribution statement with a short abstract of your 
You are also invited to contribute topics or questions to the 
interactive discussion sessions.

=> Deadline for abstract of contribution: 30 July 2014
=> Notification: 7 August 2014

You are encouraged to submit your contribution as early as possible 
before the deadline; you will then receive an early response within a 
week to make you travel plans. Please refer to for instructions how to submit.
The presentations will be published on this website after the workshop. 
Furthermore, we are negotiating with an international journal about a 
special thematic issue on mobility to be edited in 2015. This will be 
another option to publish your workshop contribution.

Deadline for registration: 21 August 2014
