While some of the qualitative methods used in sociology are already a common part of studying user interactions with products, this paper argues that further benefits could be achieved through closer interaction between these disciplines. Design could learn much from the moral and reflective critiques applied by sociologists to their own work to identify assumptions and prejudices, while sociology can benefit from the creative impetus and codesign principles adopted in design, particularly when it comes to working with and understanding children. The paper concludes by describing the Together Through Play project which sets out to explore the benefits of bringing together sociology and design in studying the area of inclusive play between disabled and non-disabled children.

Piaget suggested that children need to learn the physical rules that govern their environment before they can represent abstract concepts such as number and time. Thus, learning how objects move in space and time may underpin the development of related abstract representations (i.e., mathematics). To test this hypothesis, we captured objective measures of interceptive timing in 309 primary school children (5-11 years old), alongside scores for general motor skill and national standardized academic attainment. Bayesian estimation showed that interceptive timing (but not general motor capability) uniquely predicted mathematical ability even after we controlled for age, reading, and writing attainment. This finding demonstrates that interceptive timing is distinct from other motor skills with spec...

While dual-task approaches have clarified an association between cognitive processes and postural control, it is unclear how manual ability, which is also required for the successful completion of cognitively demanding tasks (such as putting a key into a lock), affects this relationship. Method Kinematic technology was used to explore the relationship between postural sway and manual control in healthy younger and older adults. Participants ( n = 82) remained standing to complete a visual-motor tracking task on a tablet computer. Root mean square tracking error measured manual performance, and a balance board measured deviations in centre of pressure as a marker of postural sway. Results Older adults displayed poorer manual accuracy and increased postural sway across all testing conditions. Conclusions Cognitive capacity can interact with multipl...

This research is using the Indonesian natural rubber industry as a case study. Early discussions with stakeholders highlighted a need for decision support tools to facilitate sustainability-related trade-offs in industry-wide and firm-level planning processes. The example used in this paper relates to rubber plantation replanting programmes and a three-way trade-off between customers' needs for a steady flow of rubber, an industry need to improve its environmental sustainability and rubber plantation owners' needs to maintain their financial sustainability which, in turn, influences social sustainability. An initial framework for sustainable development planning based on the case study and literature is proposed, and its use in the design of a computational simulation experiment using hybrid simulation models to predict the sustainability impacts of alternative replanting scenarios is reported.

Its effects and severity can be extremely varied, but a combination of arm impairments through weakness or spasticity and sensory deficits is common and can (i) significantly impair the ability of individuals with CP to carry out daily activities and (ii) create significant social barriers (Imms, 2008). Therapy is often used to aid the acquisition of motor skills, particularly in childhood, but a lack of physiotherapy resources means that this is ...

Studies focus on clinical measures alongside robotic intervention, but assessment data can be collected as the subjects are using the rehabilitation device. As part of an autonomous robotic rehabilitation device in primary schools, this paper introduces an assessment tool that can engage subjects and measure performance on a more granular scale across an 8 week intervention. The deployments are split in to two parts of single and dual use with a 4 week washout period in-between. Analysis of the scores achieved on the assessment task show improvement on the rehabilitation system, and the data can also be used as part of an adaptive algorithm for the robotic assistance. The data on this pilot study with 11 children with Cerebral Palsy shows that the assessment task can pick up trends of improvement across the deployments. Although the data is noisy, there is significant difference over the washout period, which shows that improvement is maintained after rehabilitation training. The order of single and dual use of the device did not influence the improvement. The simplicity of the assessment tasks makes implementation easy, and collects enough data over a short period of time for significant changes.

However, disabled workers face a range of barriers to employment, despite legislation intended to improve workplace accessibility emphasizing adaptations to the workplace, which many employers often find difficult and expensive. The Poka-Yoke approach was developed in the manufacturing industry as a way of improving productivity by reducing errors using often very simple adaptations. This paper argues that, as Poka-Yokes are designed to make life easier and improve the performance of workers without impairments, they are closer to the philosophy of Universal Design than to Accessible Design, and offer an easy and inclusive way of making work more accessible for all kind of workers. Design/methodology/approach: This paper provides a case study demonstrating the use of the Poka-Yoke approach in a sheltered work centre for disabled; highlighting how they served to improve accessibility to work by fulfilling Universal Design principles. Findings: Our research allows us to demonstrate the great potential of Poka-yokes for gaining accessibility to the workplace. The real application of this approach,

This feasibility study investigates how to motivate older people to engage with digital technology, as well as how to improve understanding of older people's needs and requirements amongst young designers. As part of this study we recorded interviews with older people which investigated their motivations to use or not use digital technologies and themes pertaining to their (dis)engagement. A virtual repository was created to make collected interviews, which were presented as social stories, available to engineering, technology and design students. In this paper we discuss the findings from a prototyping exercise with undergraduate and postgraduate students which took place in stage one at the Universities of Kent and Leeds.

Using a qualitative approach, nine people with residual arm weakness after stroke and six healthcare professionals with expertise in stroke rehabilitation were enrolled in the user-centered design process. They were asked, through semi-structured interviews, to define the needs and specification for a potential home-based rehabilitation device to facilitate self-managed arm exercise. The topic list for the interviews was derived by brainstorming ideas within the clinical and engineering multidisciplinary research team based on previous experience and existing literature in user-centered design. Meaningful concepts were extracted from questions and responses of these interviews. These concepts obtained were matched to the categories within the ICF comprehensive core set for stroke using ICF linking rules. Most of the concepts extracted from the interviews matched to the existing ICF Core Set categories. Person factors like gender, age, interest, compliance, motivation, choice, and convenience that might determine device usability are yet to be categorized within the ICF comprehensive core set. The results suggest that the categories of the comprehensive ICF Core Set for stroke provide a useful basis for structuring interviews to identify most users needs. However some personal factors (related to end users and healthcare professionals) need to be considered in addition to the ICF categories.

Outcomes were children's preference for single player or dual player mode, and changes in arm activity and kinematics. Method: Nine boys and two girls with cerebral palsy (6-12 years, mean 9 years) played assistive technology computer games in single-user mode or with school friends in an AB-BA design. Preference was determined by recording the time spent playing each mode and by qualitative feedback. We used the ABILHAND-kids and Canadian Occupational Performance Measure to evaluate activity limitation, and a portable laptop-based device to capture arm kinematics. Results: No difference was recorded between single-user and dual-user modes (median daily use 9.27 versus 11.2 min, p = 0.214). Children reported dual-user mode was preferable. There were no changes in activity limitation (ABILHAND-kids, p = 0.424; COPM, p = 0.484) but we found significant impr...

Given the need to distribute its products to customers on the 17,000 islands making up availability of ports are major factors in managing fertiliser product lifecycles. However, managing the flow of material around a port is a complex process, affected by a range of socio-technical factors. This paper proposes a conceptual model of supply network processes and their relationships to infrastructures such as ports based on a socio-technical systems analysis of material flow. Results from an application of the model to explore how changes to a port is operated affect material flow. These results were used to inform the development of an agent based simulation model to support decision makers in investigating the effects of their decisions in considering the impact of potential management interventions on the flow of materials within the port. The conceptual and simulation models are illustrated using a case study taken from a port in the Indonesian fertiliser industry.

Nonetheless, postural control and eye-hand coordination are linked functionally. For example, a stable platform is required for precise manual control tasks (e.g. handwriting) and thus such skills often cannot develop until the child is able to sit or stand upright. This raises the question of the strength of the empirical relationship between measures of postural stability and manual motor control. We recorded objective computerised measures of postural stability in stance and manual control in sitting in a sample of school children (n = 278) aged 3-11 years in order to explore the extent to which measures of manual skill could be predicted by measures of postural stability. A strong correlation was found across the whole sample between separate measures of postural stability and manual control taken on different days. Following correction for age, a signif...
