Overcoming barriers and increasing independence: service robots for elderly and disabled people
This paper discusses the potential for service robots to overcome barriers and increase independence of
elderly and disabled people. It includes a brief overview of the existing uses of service robots by disabled and elderly
people and advances in technology which will make new uses possible and provides suggestions for some of these new
applications. The paper also considers the design and other conditions to be met for user acceptance. It also discusses
the complementarity of assistive service robots and personal assistance and considers the types of applications and
users for which service robots are and are not suitable
BCI controlled robotic arm as assistance to the rehabilitation of neurologically disabled patients
This presentation summarises the development of a portable and cost-efficient BCI controlled assistive technology using a non-invasive BCI headset 'OpenBCI' and an open source robotic arm, U-Arm, to accomplish tasks related to rehabilitation, such as access to resources, adaptability or home use. The resulting system used a combination of EEG and EMG sensor readings to control the arm, which could perform a number of different tasks such as picking/placing objects or assist users in eating
User Based Development and Test of the EXOTIC Exoskeleton:Empowering Individuals with Tetraplegia Using a Compact, Versatile, 5-DoF Upper Limb Exoskeleton Controlled through Intelligent Semi-Automated Shared Tongue Control
This paper presents the EXOTIC- a novel assistive upper limb exoskeleton for individuals with complete functional tetraplegia that provides an unprecedented level of versatility and control. The current literature on exoskeletons mainly focuses on the basic technical aspects of exoskeleton design and control while the context in which these exoskeletons should function is less or not prioritized even though it poses important technical requirements. We considered all sources of design requirements, from the basic technical functions to the real-world practical application. The EXOTIC features: (1) a compact, safe, wheelchair-mountable, easy to don and doff exoskeleton capable of facilitating multiple highly desired activities of daily living for individuals with tetraplegia; (2) a semi-automated computer vision guidance system that can be enabled by the user when relevant; (3) a tongue control interface allowing for full, volitional, and continuous control over all possible motions of the exoskeleton. The EXOTIC was tested on ten able-bodied individuals and three users with tetraplegia caused by spinal cord injury. During the tests the EXOTIC succeeded in fully assisting tasks such as drinking and picking up snacks, even for users with complete functional tetraplegia and the need for a ventilator. The users confirmed the usability of the EXOTIC
Mapping Robots to Therapy and Educational Objectives for Children with Autism Spectrum Disorder
The aim of this study was to increase knowledge on therapy and educational objectives professionals work on with children with autism spectrum disorder (ASD) and to identify corresponding state of the art robots. Focus group sessions (n = 9) with ASD professionals (n = 53) from nine organisations were carried out to create an objectives overview, followed by a systematic literature study to identify state of the art robots matching these objectives. Professionals identified many ASD objectives (n = 74) in 9 different domains. State of the art robots addressed 24 of these objectives in 8 domains. Robots can potentially be applied to a large scope of objectives for children with ASD. This objectives overview functions as a base to guide development of robot interventions for these children
Autonomous behaviour in tangible user interfaces as a design factor
PhD ThesisThis thesis critically explores the design space of autonomous and actuated artefacts, considering
how autonomous behaviours in interactive technologies might shape and influence users’
interactions and behaviours.
Since the invention of gearing and clockwork, mechanical devices were built that both fascinate
and intrigue people through their mechanical actuation. There seems to be something magical
about moving devices, which draws our attention and piques our interest. Progress in the
development of computational hardware is allowing increasingly complex commercial products
to be available to broad consumer-markets. New technologies emerge very fast, ranging from
personal devices with strong computational power to diverse user interfaces, like multi-touch
surfaces or gestural input devices. Electronic systems are becoming smaller and smarter, as they
comprise sensing, controlling and actuation. From this, new opportunities arise in integrating
more sensors and technology in physical objects.
These trends raise some specific questions around the impacts smarter systems might have
on people and interaction: how do people perceive smart systems that are tangible and what
implications does this perception have for user interface design? Which design opportunities are
opened up through smart systems? There is a tendency in humans to attribute life-like qualities
onto non-animate objects, which evokes social behaviour towards technology. Maybe it would be
possible to build user interfaces that utilise such behaviours to motivate people towards frequent
use, or even motivate them to build relationships in which the users care for their devices. Their
aim is not to increase the efficiency of user interfaces, but to create interfaces that are more
engaging to interact with and excite people to bond with these tangible objects.
This thesis sets out to explore autonomous behaviours in physical interfaces. More specifically, I
am interested in the factors that make a user interpret an interface as autonomous. Through a
review of literature concerned with animated objects, autonomous technology and robots, I have
mapped out a design space exploring the factors that are important in developing autonomous
interfaces. Building on this and utilising workshops conducted with other researchers, I have
vi
developed a framework that identifies key elements for the design of Tangible Autonomous
Interfaces (TAIs). To validate the dimensions of this framework and to further unpack the
impacts on users of interacting with autonomous interfaces I have adopted a ‘research through
design’ approach. I have iteratively designed and realised a series of autonomous, interactive
prototypes, which demonstrate the potential of such interfaces to establish themselves as social
entities. Through two deeper case studies, consisting of an actuated helium balloon and desktop
lamp, I provide insights into how autonomy could be implemented into Tangible User Interfaces.
My studies revealed that through their autonomous behaviour (guided by the framework) these
devices established themselves, in interaction, as social entities. They furthermore turned out to
be acceptable, especially if people were able to find a purpose for them in their lives. This thesis
closes with a discussion of findings and provides specific implications for design of autonomous
behaviour in interfaces
