abstract = {We are at the verge of living in a world where computing
has become ubiquitous. However, ubiquitous computing has not
developed as expected, where computing devices are embedded
in the things that surround us making them smart. Instead,
computing capabilities are accessed ubiquitously through a
manifold of small interactive devices that people carry with
them at all times and use and combine opportunistically. In
consequence, the need to interact with multiple devices
arises in unexpected ways, or as called in this thesis "in
the wild". The main goal of this thesis is to raise
awareness of the unique properties of multi-device
interaction in the wild and the misalignment between these
properties and current efforts in academia and industry. To
this end, the thesis classifies possible types of
multi-device interaction as simultaneous or sequential use
towards a common or distinct tasks. To support these types
of interaction in the wild, systems must enable the
opportunistic rearrangement of devices where transitions are
robust and can be performed in ad-hoc situations. The second
part of the thesis explores how application state can serve
as a conceptual model for users and designers to enable
multi-device interaction in the wild. The concept supplies
users with a first-class interactive object representing the
state of applications, similar to how the file represents
the state of information, which can be manipulated with
tools that are separated from the task. It is this
separation that allows application state to be used in
unexpected situations, making it a good fit for multi-device
interaction in the wild. The final part of the thesis
elaborates on how the concept of application state can be
integrated into current interactive systems. A simple
programming interface was developed that separates state
extraction from state sharing: The task applications provide
the functionality needed to extract and restore their state
into a standardized container, which is then managed and
shared through designated state management tools. After
describing the state exchange system architecture, the
thesis explores how to support legacy applications in
implementing state extraction and restoration up to complete
automation. There is, however, a trade-off between
automating state extraction and providing a semantically
meaningful state that can be shared between different
applications of the same type to transition tasks between
device classes.},
