The Future of Context-Awareness: How wearables can learn about us and
our environment at run-time

Existing context-aware wearables typically directly associate signal
patterns to a user’s context, without taking into account previous
activities or the person’s location. However, such complementary
information may influence the significance of a signal pattern, improve
the performance in recognizing context, and enable more fine-grained
distinction of activities. The challenge is to achieve such state-aware
context recognition from wearables only, i.e., without being dependent
on pre-installed infrastructure or the training of complex classifiers.
In this talk, we introduce the concept of semantic maps as environment
representation for context-aware assistants in daily life. Semantic
maps describe the location and state of objects, e. g., open windows,
running water taps or closed doors. Such maps can be used to infer
higher-level activities of an inhabitant, and to constrain his location
within the environment. We discuss a Bayesian filter framework that
builds such maps from the data of wearables and in return estimates the
person’s position within the map, without the need for any pre-installed
localization infrastructure. By continuously adding new information to
the semantic map, this proposed framework accumulates knowledge about
the place in a self-learning manner. We demonstrate the potential of
this tool in real-world settings, where we monitor people during their
daily life at home, without having to install any infrastructure in
the building. Such a system can be deployed efficiently and without
professional support. Furthermore, the introduction of semantic maps as
state argument in context-awareness is a major step towards advanced
monitoring tools and wearable assistants in medicine, sports and
daily-life applications. This talk will presents working prototypes,
including the first smartphone-based localization system that robustly
tracks people over a long time, using motion data only.

Wireless sensor networks and intelligent sensing technologies have
boosted many promising smart-city applications which provide diverse
ambient intelligence for understanding city dynamics and improving
human well-being. This talk will systematically review some research
activities and technical evolution from conventional WSNs towards
smart-city technologies including static and dynamic wireless networking
and communications, wearable computing, mobile sensing, crowdsourcing,
and data analytics. Through these reviews, we will demonstrate how these
sensor-assisted applications exploit the information collected by WSNs
wearable devices, smartphones, and crowdsourcing systems to bridge the
cyber and the physical worlds.

Textile enjoys a high coverage rate both time-wise and space-wise in
everyone’s life. Utylizing this “worn by default”, smart textile
becomes a unique resource for information retrieval and feedback in (not
only) wearable computing. This talk presents mainly 3 novel sensing and
feedback modalities using texile and their application for some key topics
in wearable and ubiquitous computing, including: human computer interface,
monitoring activities of daily living, nutrition, sport and etc.

F-Droid is an app distribution platform for Android. It is based on
the repository system known from Linux distros - anyone can set up a
repository with apps, and users can download and install apps from it.
The main difference between F-Droid and other app stores alternative to
Google Play is that F-Droid is completely Free Software. This makes the
project a key component of Android as an open source and decentralized
system.
Our main repository has over 1,500 apps with more than 60,000 regular
users. This talk will mainly focus on how the Android client is written
and all the challenges it faces. For example:
How do you make it scale to thousands of apps at a time?
How can you make it light on network usage?
How can you keep it secure?
How can it be a package manager on its own? (regular apps can't do this)
