Internet of Things enabled sedentary behaviour change in office workers: development and feasibility of a novel intervention (WorkMyWay)

Sedentary behaviour (SB) without breaks is associated with adverse health outcomes. The prevalence of prolonged sitting at work among office workers makes a case for SB interventions to target this setting and population. Everyday mundane objects augmented with microelectronics and ubiquitous computing represent a novel mode of delivery for behaviour change interventions enabled by the Internet of Things (IoT). However, there is insufficient research to guide the design of interventions delivered with smart objects. This research addresses this gap by developing WorkMyWay, a workplace SB intervention delivered with IoT-enabled office objects (e.g. smart water bottles and cups), and evaluating its feasibility and acceptability in an 8-week “in-the-wild” study. This thesis made 4 contributions across the disciplines of behavioural medicine and human-computer interactions (HCI). The first contribution is the development of the WorkMyWay intervention, which is informed by findings from a systematic scoping review of prior research in this field (Chapter 3), a diary-probed interview study with 20 office workers (Chapter 4), and a series of technology audit, prototyping, human-centred design, and requirement engineering processes (Chapter 5). Findings from the feasibility study (Chapter 6) suggest that despite technical issues with the data connection, participants perceive high value of WorkMyWay in changing their SB. The intervention is potentially implementable in office-based workplaces, as long as connectivity issues are fixed. Recommendations are made on improvements and a series of future studies in accordance with the Medical Research Council’s guidance on complex intervention development and evaluation. Second, this thesis deepens the theoretical understanding of SB change, by following the Behaviour Change Wheel framework (including the COM-B model, theoretical domain framework, and taxonomies of Behaviour Change Techniques (BCT)) throughout intervention design and evaluation. The intervention contents are specified using the BCT taxonomies (Chapter 5) and informed by the first published COM-B analysis of office worker’s prolonged sitting behaviour at work (Chapter 4). This allows the feasibility study (Chapter 6) to contribute to theory development by matching the interview questions and psychological measures (e.g. strength of habit) with the BCTs (e.g. action planning, prompts and cues) and associated theoretical underpinnings (e.g. goal accessibility). It also allows implementation issues to be considered in light of how well those theories and theory-informed BCTs can work in real-life settings. Third, this thesis makes a methodological contribution by documenting an interdisciplinary approach to develop a digital behaviour change intervention and a model for applying and developing theories of behaviour change in the wild. This helps address the challenge identified in Chapter 3, by bridging the gap between HCI and behavioural medicine, and catalyse the process of feeding technological innovations downstream to health practice and intervention research. Fourth, this research contributes to the HCI literature by proposing a 2×2 matrix framework to guide the design of technology for sustainable behaviour change. On one hand, the framework unifies some of the existing visions and concepts about ubiquitous computing and applies them to the context of behaviour change, by considering the type of cognitive process (automatic versus reflective, based on the dual process model) through which a persuasive design influences the behaviour. For another, the framework considers the required dosage of their technology intervention to maintain the behaviour, or the distribution of changes between the physical world and the human cognition

The impact of synchronous inter-networked teacher training in ICT integration.

This research aimed to provide fresh perspectives and experiences in technology-based learning, in an endeavour to produce new knowledge that would further inform the literature on the utilisation of technology in education. The Case Study research (Merriam, 1988) attempted to develop an understanding of the change in pre-service teacher trainees' pedagogical practices in the integration of ICT in learning environments during a 12-week undergraduate course where synchronous networked tasks were developed and implemented. The contributions by the trainees (n=16) to the process of the iterative task design, post-task discussions, and commentaries on a Bulletin Board System, provided insights to the research question regarding changing beliefs and the impact of synchronous networking in affecting such change. This qualitative data was supported by quantitative data in the form of weekly surveys that situated synchronous and asynchronous task activities and cognitive outcomes (Knipe & Lee, 2002). In summary, the research highlighted a development of academic competencies (Morrison & Collins, 1996) considered appropriate for informed ICT integration; namely, generic, epistemic and declarative competencies. In addition, after taking into consideration the competencies developed during this Case Study, a framework consisting of four key elements, namely, the communication, the task, the learning and the technology, was drawn. It is thus anticipated that the competencies and the framework contribute new knowledge to the literature on technology in education on how best facilitate the 'informed' integration of ICT (Towndrow & Vallance, 2004) by teachers to support 'good' learning (Goodyear, 2001)

Future visioning system for designing and developing new product concepts in the consumer electronics industries

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis discusses development of a future visioning system model that can be adopted to create new product concepts for consumer electronics companies operating in a highly competitive business environment. The research work investigates consumer electronic product companies and their market environment to identify problematic issues and indicates that a proactive new product strategy which opens new markets through developing concept-led products is a strategic priority, thus the concept development stage in new product development process is in need of improvement. An evaluation of existing concept development tools for the purpose of proactive product strategy is presented and concludes that future visioning procedure is the most appropriate tool. To develop a future visioning system model as a concept development tool, the theoretical future visioning system models are analysed and mapped to extract essential structure and contents of future visioning procedure. The consequent future visioning system model is then revised according to the findings and suggestions from the field research work which investigated four major consumer electronics product companies in practice. The findings also validates the necessity of adopting a proactive product strategy and evaluates acceptability of the future visioning system model for practical use. The final future visioning system model is defined after the opinions of the design managers are considered and applied. The major suggestions from the research findings are: (1) Executing proactive product strategy can be a valuable strategic tool (2) A new process is necessary for the companies to create one-step-ahead product (3) Future visioning system is recommended as an advanced approach that creates new product concept. (4) Future visioning system model should consist of eight stages: project initiation, environmental scanning, future visioning, generating product concepts, scenario planning, concept testing, concept visualisation, and finalized concepts. (5) Product concepts can be generated from future vision by applying backcasting. (6) Scenario planning should be used in the future visioning system model as a concept testing tool providing objective validating criteria. (7) Executing a future visioning system model creates new roles for the designer such as information integrator, process moderator, and futurist
