thesisIncreased demand for powered wheelchairs and their inherent mobility limitations have prompted the development of omnidirectional wheelchairs. These wheelchairs provide improved mobility in confined spaces, but can be more difficult to control and impact the ability of the user to embody the wheelchair. We hypothesize that control and embodiment of omnidirectional wheelchairs can be improved by providing intuitive control with three degree of freedom (3-DOF) haptic feedback that directly corresponds to the degrees of freedom of an omnidirectional wheelchair. This thesis introduces a novel 3-DOF Haptic Joystick designed for the purpose of controlling omnidirectional wheelchairs. When coupled with range finders, it is able to provide the user with feedback that improves the operator's awareness of the area surrounding the vehicle and assists the driver in obstacle avoidance. The haptic controller design and a stability analysis of the coupled wheelchair joystick systems are presented. Experimental results from the coupled systems validate the ability of the controller to influence the trajectory of the wheelchair and assist in obstacle avoidance

Access to Eye-Gaze Control Technology for Children with Cerebral Palsy

Children with cerebral palsy (CP), whose disability may limit speech production and motor skills, are often considered good candidates for the use of eye-gaze technology to access communication, learning and play. At present, little is known about the skills needed to control this technology, which can make it difficult for clinicians to make decisions, or to manage expectations around progress. This is further complicated by the emergence of “teaching” software packages, claiming to improve basic skills such as cause and effect. Children with CP are known to be at a higher risk of vision disorders, including those related to functional vision – how a child functions in vision related activities. These skills (in particular fixation and gaze switching) are similar to those required to make use of eye-gaze technology, so are likely to impact on children’s performance. This thesis uses typically developing children to provide baseline information and to observe how they respond to tasks which were incrementally lowered in terms of cognitive demand. Over three rounds of experiments a pattern emerged that children aged 32 months were able to use it with only minimal instruction. The impact of teaching on performance was also investigated in this section of the study. A group of children with CP were recruited to investigate the most effective way of assessing functional vision skills in this group, with results indicating behavioural measures were most effective. A final study with children with CP used the activities above to look at the performance of this group on eye-gaze tasks. Results suggested good functional gaze control skills were related to better performance on a novel eye-gaze task. The findings suggest that some children may be at a “developmental advantage” if their functional vision and cognitive skills are more developed

Ageing and Technology: Perspectives from the Social Sciences

The booming increase of the senior population has become a social phenomenon and a challenge to our societies, and technological advances have undoubtedly contributed to improve the lives of elderly citizens in numerous aspects. In current debates on technology, however, the "human factor" is often largely ignored. The ageing individual is rather seen as a malfunctioning machine whose deficiencies must be diagnosed or as a set of limitations to be overcome by means of technological devices. This volume aims at focusing on the perspective of human beings deriving from the development and use of technology: this change of perspective - taking the human being and not technology first - may help us to become more sensitive to the ambivalences involved in the interaction between humans and technology, as well as to adapt technologies to the people that created the need for its existence, thus contributing to improve the quality of life of senior citizens

Cognition in action C-i-A: Rethinking gesture in neuro-atypical young people: A conceptual framework for embodied, embedded, extended and enacted intentionality

The three aims of my interdisciplinary thesis are: -To develop a conceptual framework for re-thinking the gestures of neuro-atypical young people, that is non-traditional and non-representational -To develop qualitative analytical tools for the annotation and interpretation of gesture that can be applied inclusively to both neuro-atypical and neuro-typical young people -To consider the conceptual framework in terms of its theoretical implications and practical applications Learning to communicate and work with neuro-atypical young people provides the rationale and continued impetus for my work. My approach is influenced by the limited social, physical and communicative experiences of young people with severe speech and motor impairment, due to cerebral palsy (SSMI-CP). CP is described as: a range of non-progressive syndromes of posture and motor impairment. The aetiology is thought to result from damage to the developing central nervous system during gestation or in the neonate. Brain lesions involve the basal ganglia and the cerebellum; both these sites are known to support motor control and integration. However, gaps in theoretical research and empirical data in the study of corporeal expression in young people with SSMI-CP necessitated the development of both an alternative theoretical framework and new tools. Biological Dynamic Systems Theory is proposed as the best candidate structure for the reconsideration of gesture. It encompasses the global, synthetic and embodied nature of gesture. Gesture is redefined and considered part of an emergent dynamic, complex, non-linear and self-organizing system. My construct of Cognition-in-Action (C-i-A) is derived from the notion of knowing-as-doing influenced by socio-biological paradigms; it places the Action-Ready-Body centre stage. It is informed by a theoretical synthesis of knowledge from the domains of Philosophy, Science and Technology, including practices in the clinical, technology design and performance arts arenas. The C-i-A is a descriptive, non-computational feature-based framework. Its development centred around two key questions that served as operational starting points: What can gestures reveal about children’s cognition-in-action? and Is there the potential to influence gestural capacity in children? These are supported by my research objectives. Three case studies are presented that focus on the annotation and interpretative analyses of corporeal exemplars from two adolescent males aged 16.9 and 17.9 years, and one female girl aged 10.7 years. These exemplars were contributed to the Child Gesture Corpus by these young people with SSMI-CP. The Gesture-Action-Entity (GAE) is proposed as a unit of interest for the analysis of procedural, semantic and episodic aspects of our corporeal knowledge. A body-based-action-annotation-system (G-ABAS) and Interpretative Phenomenological Analysis methodology is applied for the first time to gesture (G-IPA). These tools facilitate fine-grained corporeal dynamic and narrative gesture feature analyses. Phenomenal data reveal that these young people have latent resources, capacities and capabilities that they can express corporeally. Iteration of these interpretative findings with the Cognition-in-Action framework allows for the inference of processes that may underlie the strategies they use to achieve such social-motor-cognitive functions. In summary, their Cognition-in-Action is brought-forth, carried forward and has the potential to be culturally embodied. The utility of C-i-A framework lies in its explanatory power to contribute to a deeper understanding of child gesture. Furthermore, I discuss and illustrate its potential to influence practice in the domains of pedagogy, rehabilitation and the design of future intimate, assistive and perceptually sensitive technologies. Such technologies are increasingly mediating our social interactions. My work offers an ecologically valid alternative to tradition conceptualization of perception, cognition and action. My thesis contributes both new knowledge and carries implications across the domains of movement science, gesture studies and applied participatory performance arts and health practices

Measuring Behavior 2018 Conference Proceedings

These proceedings contain the papers presented at Measuring Behavior 2018, the 11th International Conference on Methods and Techniques in Behavioral Research. The conference was organised by Manchester Metropolitan University, in collaboration with Noldus Information Technology. The conference was held during June 5th – 8th, 2018 in Manchester, UK. Building on the format that has emerged from previous meetings, we hosted a fascinating program about a wide variety of methodological aspects of the behavioral sciences. We had scientific presentations scheduled into seven general oral sessions and fifteen symposia, which covered a topical spread from rodent to human behavior. We had fourteen demonstrations, in which academics and companies demonstrated their latest prototypes. The scientific program also contained three workshops, one tutorial and a number of scientific discussion sessions. We also had scientific tours of our facilities at Manchester Metropolitan Univeristy, and the nearby British Cycling Velodrome. We hope this proceedings caters for many of your interests and we look forward to seeing and hearing more of your contributions
