Brotate and Tribike: Designing Smartphone Control for Cycling

The more people commute by bicycle, the higher is the number of cyclists using their smartphones while cycling and compromising traffic safety. We have designed, implemented and evaluated two prototypes for smartphone control devices that do not require the cyclists to remove their hands from the handlebars - the three-button device Tribike and the rotation-controlled Brotate. The devices were the result of a user-centred design process where we identified the key features needed for a on-bike smartphone control device. We evaluated the devices in a biking exercise with 19 participants, where users completed a series of common smartphone tasks. The study showed that Brotate allowed for significantly more lateral control of the bicycle and both devices reduced the cognitive load required to use the smartphone. Our work contributes insights into designing interfaces for cycling.Comment: 22nd International Conference on Human-Computer Interaction with Mobile Devices and Services (MobileHCI '20), October 5--8, 2020, Oldenburg, German

Quality and field of vision - a review of the needs of drivers and riders: phase 1 report.

It is the responsibility of the Department of the Environment, Transport and the Regions (DETR) to promote safe use of the UK road network. Driver vision has been identified as major determinant to this and factors which impede it require further investigation. This project is specifically concerned with the effect on driver / rider vision of: • windscreen and visor tinting, installed light transmission, haze, abrasion, damage and repair, • the use and positioning of wider structural member (particularly A-pillars) to improve crashworthiness, aerodynamics and rigidity. The first phase of the work is to understand the current status regarding the above factors and the rationale for it. A variety of sources have been consulted for this information including: • establishing contact with interested parties, • reviewing and establishing the basis of EC Directives and other regulations, • reviewing and summarising previous, current and proposed research, • analysing available accident data, • interviewing drivers and riders. A detailed work plan for the remainder of the project has been developed based on the results of the Phase 1 findings and on the professional experience ICE Ergonomics has in this field

The potential of haptic interfaces for urban cyclists in China

The thesis is the culmination of a two year investigation into revolutionary mobile communication interface designs for cyclists in large cities in China. The research came about as a result of my interest in the growing trend of cyclists making phone calls while cycling in China. There is current discussion in China about whether creating legislation would be a good option for controlling mobile phone use while cycling. My analysis of website articles indicates, however that fining cyclists for making mobile phone calls while cycling would be ineffective. In a sense my research is concerned with this view. I hope to demonstrate through this research, therefore that the problem can be addressed through product design rather than through stricter laws and changes to legislation. This current project looks at: Why and how this phenomenon of cyclists making phone calls arose in current modern China, what are the implications, hidden problems and potential opportunities for the existent system? How can these problems be addressed through design with a view towards creating a better interface for cyclists to interact with other people and the traffic system whilst cycling in urban cities? The final design scenarios are used to illustrate how cyclists being an integral to interact with the systems and stay in connect with others. How and why haptic interfaces can contribute for the cyclists’ safety in a broader traffic situation in China

User-centred car design and the role of feedback in driving

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.A survey of car manufacturers reveals an impressive list of upcoming technologies, the combined effect of which is likely to have a profound impact upon feedback to the driver. Feedback is information that the situation provides back to the driver and is specified with reference to content, source, and timing. Feedback quality is achieved when the information requirements of the task, derived from a new task analysis of driving, are matched to the sources, content, and timing of feedback provided by the environment and the vehicle. An exploratory on-road study begins by observing that better quality feedback is implicated in increasing driver's situational awareness (even though drivers have little self awareness of this fact), and optimising mental workload. The exploratory level of analysis builds into the experimental, whereby a highly controlled simulator study replicates and builds upon these findings. Feedback is again seen to positively influence situational awareness, where changes in driver's confidence ratings as to the presence or absence of feedback information in the simulation were observed, according to the modality of feedback presented. This was achieved with a probe recall paradigm, and using psychophysical techniques as a useful extension to the Situational awareness Global Assessment Technique (SAGAI). Similarly, an analysis of mental workload via the NASA TLX self report questionnaire demonstrates that a combination of visual, steering force feedback and auditory feedback gives rise to lower mental workload, lower driver frustration, and lower, though possibly more realistic self ratings of performance. This knowledge can be discussed with reference to a feedback framework of driving that provides the theoretical backdrop to the key psychological variables implicated in driving task performance. Overall, the findings contribute to knowledge in terms of new and imaginative ways of designing future vehicle technologies in order to maximise safety, efficiency, and enjoyment.This research is funded by the Hamilton Research Studentship

The design of fashionable wearables to promote sustainable behaviours in smart cities

A falta de sustentabilidade que ameaça o nosso futuro necessita de atenção urgente, exigindo uma abordagem holística. Contudo, ações explicitamente destinadas a mudar o comportamento humano não são muito comuns quando, paradoxalmente, grande parte do impacto ambiental está associado ao comportamento das pessoas na sua vida quotidiana. Muitas ações insustentáveis estão atualmente a ter lugar nas cidades, causando impactos negativos. As cidades oferecem respostas a muitas necessidades da vida, o que motiva as pessoas a procurarem estes espaços, causando uma concentração populacional. Esta procura do meio urbano decorre da expectativa de ter melhor qualidade de vida. A mobilidade urbana, por seu lado, que pode ser vista como um facilitador do acesso a múltiplas componentes da vida quotidiana, incluindo empregos, educação, cuidados de saúde e muitos outros pode, também, gerar congestionamentos, poluição, um acrescido consumo energético e aumento de stress, afetando diretamente a qualidade de vida das pessoas. Neste contexto, as escolhas pessoais quanto à mobilidade têm um impacto substancial na vida quotidiana. Contudo, dado que as cidades estão a tornar-se “inteligentes”, graças à aplicação de tecnologias emergentes de identificação, deteção e comunicação, nomeadamente com recurso à tecnologia da Internet das Coisas (IoT – Internet of Things), abrem-se novas possibilidade para alteração dos comportamentos da vida quotidiana, com impacto na sustentabilidade. Este desenvolvimento tecnológico tem vindo a ser explorado em múltiplas áreas, incluindo energia / instalações, transportes, cuidados de saúde, segurança, monitorização doméstica, entre outras, sendo reconhecido como uma tendência com forte crescimento a curto prazo. Neste contexto, este estudo pretendeu explorar a possibilidade de promover comportamentos de mobilidade considerados mais sustentáveis através do design de artigos de moda que possam funcionar como elementos ativos no sistema de uma cidade “inteligente”. A possibilidade de combinação de funcionalidade e sedução, o poder motivador da moda, combinado com tecnologia avançada e sensores, foi entendido como tendo fortes argumentos para ser bem-sucedido na modificação do comportamento. Como ocorre com muitos outros produtos, os produtos da moda são pensados para responder às expetativas, necessidades e limitações das pessoas, onde convivem aspetos funcionais, ergonómicos, afetivos e emocionais, fortemente focados na experiência e no envolvimento, mas com assumido enfoque na componente estética, estilo, estatuto e formação de identidade. Estes são parte essencial da mudança de comportamento. As tecnologias digitais embutidas nos têxteis oferecem oportunidades significativas de alargamento das funcionalidades dos produtos de moda, incluindo a comunicação, transformação da informação do nosso corpo em dados, conduzindo energia, brilhando, crescendo e muitos outros. Alguns bons exemplos deste tipo podem já ser encontrados na promoção da segurança humana, saúde/ bem-estar, treino militar e entretenimento. Nesta investigação, o termo “fashionable wearables” é adotado para enfatizar a combinação de moda e tecnologia. Importa ressalvar que o objetivo deste estudo não foi trabalhar questões de moda sustentável, que é outra questão vital, mas que fica fora do recorte deste trabalho. O principal objetivo foi explorar como e em que medida as soluções de “fashionable wearables” podem promover comportamentos mais sustentáveis em cidades inteligentes. As escolhas de mobilidade foram selecionadas como comportamentos-alvo que se pretendem alterar. Para o conseguir, foi utilizada uma metodologia mista, de acordo com a abordagem do Design Centrado no Humano. A abordagem do Design para a Mudança de Comportamento foi utilizada para fornecer soluções a um nível do design conceptual. Este estudo de doutoramento foi pensado como uma investigação pelo design, no qual o design conceptual desempenhou um papel formativo na geração do conhecimento. Utilizámos dados qualitativos e quantitativos para explorar o contexto, identificar os tópicos, gerar ideias e soluções e verificar conceitos para cumprir objetivos. A metodologia proposta foi dividida em cinco fases: (1) Compreender, (2) Descobrir, (3) Design Conceptual, (4) Protótipo, e (5) Avaliação. Na primeira fase, aprofundámos os conhecimentos teóricos sobre temas de investigação e fizemos revisões de literatura. Compreendemos a noção atual de sustentabilidade e do comportamento sustentável com entrevistas a peritos e métodos de mapeamento de conceitos. Identificámos comportamentos sustentáveis e exemplificámo-los considerando domínios da vida quotidiana e tipos de comportamento. Determinámos os comportamentos que têm um impacto mais negativo na vida quotidiana. No final, decidimos concentrar-nos nos comportamentos de mobilidade. Na segunda fase, explorámos os obstáculos à adoção e/ou manutenção de comportamentos sustentáveis. Conduzimos sessões de grupos focais para descobrir necessidades dos utilizadores, exigências, problemas e desculpas razoáveis para não adotar ações de mobilidade sustentável e níveis de preferência/satisfação dos modos de mobilidade. Depois de traçarmos as oportunidades potenciais para um maior desenvolvimento, identificámos os comportamentos sustentáveis alvo, em que nos iriamos focar, em particular o caminhar e partilhar bicicletas, na vida da cidade. Na terceira fase, identificámos utilizadores-alvo, desenvolvemos personas e um cenário narrativo representando potenciais perfis de utilizadores e problemas. Ilustrámos storyboards, gerámos ideias. Apesar de o estudo se rever no paradigma sócio-critico, as soluções conceptuais geradas foram baseadas em Estratégias de Mudança de Comportamento e problemas observados em potenciais utilizadores, bem como em oportunidades futuras recolhidas a partir de relatórios de previsão e não apenas nas possibilidades tecnológicas atuais. Realizámos entrevistas de avaliação por peritos para alimentar a ideação, fazer a avaliação e refinamento das propostas, com a participação de especialistas em diferentes campos do saber, incluindo design de interfaces, produto, têxtil, moda, interação e ciência, incluindo engenharia, computador, física, software. Na quarta fase, visualizámos ideias conceptuais de produtos e sistemas com “storyboarding” de soluções. Desenvolvemos “mock-ups” e um protótipo em vídeo do vestuário de moda, para permitir a avaliação da experiência de utilização antecipada. O protótipo de vídeo forjou o que seriam as futuras ofertas de tecnologia inteligente em termos de interface e exibição do e-textile com animação por computador e ferramentas de edição de vídeo. Demos aos potenciais utilizadores a impressão de que estavam a interagir com um sistema real antes deste existir, o que proporcionou a tangibilização possível da solução para a fase de avaliação. Na última fase, avaliámos o desenho conceptual dum “fashionable wearable” para testar a motivação do utilizador em aderir ao comportamento desejável e a usabilidade do artefacto. Utilizámos o Questionário de Experiência de Utilização (UEQ), avaliando a sua experiência considerando a perspicuidade, eficiência, estímulo, atratividade, novidade e fiabilidade do design conceptual. Obtivemos também feedback e sugestões dos utilizadores. O conceito foi avaliado positivamente. Encontrámos um estímulo significativo para a mudança de comportamento, que sugere que os artigos de moda, se usados como parte de uma estratégia de mudança de comportamento, podem influenciar a adoção de comportamentos mais sustentáveis no contexto da mobilidade urbana em cidades “inteligentes”. Em última análise, esta investigação de doutoramento contribuiu para o campo do design de moda, design para comportamento sustentável, design para mudança de comportamento e sustentabilidade.The lack of sustainability that threatens our future needs urgent attention, requiring a holistic approach. However, actions explicitly aimed at changing human behaviour are not very common when, paradoxically, much of the environmental impact is associated with the behaviour of users in everyday life. Many unsustainable actions are currently taking place in cities, causing negative impacts. Cities offer access to many requirements of life that causes a population shift. Significantly, mobility facilitates access to all necessities of life in urban areas. Considering the potential to generate congestion, pollution and preventing freedom of accessibility, mobility can directly affect the quality of air and quality of life. Since cities are becoming smart thanks to emerging technologies, smart mobility has growing in importance and concerns more about being effective and sustainable. In this matter, mobility choices have a substantial impact on daily life. This study intended to promote mobility behaviours considered more sustainable through the design of fashionable wearables that can work as active elements of the system in the smart city context. The combination of body-related functionality and seduction, as well as the motivating power of fashion, combined with advanced technology and sensors, provided a strong motivation for contributing to behaviour change. The main objective was to explore how and to what extent solutions of fashionable wearables can promote more sustainable behaviours in smart cities. Mobility choices were selected as target behaviours that are desired to be altered. To achieve this, a mixed methodology according to the Human-Centred Design approach was used to gain information about needs and demands. Design for Behaviour Change strategies were used to provide solutions at a conceptual design level. We evaluated the conceptual design with a key element of fashionable wearable to test the motivation of the user to use and adhere the usability of the design to determine behaviour intervention. The conceptual design was evaluated positively, and we found the meaningful stimulus for the behaviour change

Improving the aesthetic and other experiential design aspects of bicycle paths in Western Australia

Governments around Australia are in the process of promoting cycling as both a sustainable form of transport that can be a viable alternative to the motor vehicle, particularly for shorter trips, and as a healthy recreational pursuit that can play an important role in addressing the growing problem of obesity and illnesses associated with a sedentary lifestyle in the community. As part of this initiative, the development of effective and efficient infrastructure for bicycles is seen as a vital step for achieving higher participation rates. A major component of the nation’s bicycle infrastructure is the growing networks of paved paths and natural surface trails located in both urban and regional areas. A well-designed path or trail must meet agreed standards related to safety and function and, in order to achieve maximum usage, it must also create a desirable riding experience. While requirements for safety and function are well understood by path and trail planners, little empirical information has been produced to enable these planning professionals to understand the elements that impact upon an individual’s riding experience and to then incorporate them into the design process. Accordingly, the overall aim of this research was to investigate how the aesthetic, cultural and other experiential design aspects of bicycle paths and trails can enhance the perceived riding experience. A secondary objective of the project involved a determination of the procedural factors guiding the local path and trail design protocols and process. A third objective was to gain an insight into the most effective method of communicating the benefits of these riding environments to important target groups. Following the establishment of a theoretical framework incorporating the psychophysical nature of cycling, the effect of landscape and current design practices, the research progressed through several stages beginning with an autoethnography examining the researcher’s extensive experience in the promotion of cycling in Western Australia, augmented by in-depth discussions with leading key informants. This was followed by a mix of quantitative and qualitative methodology to gauge perception of various elements of in-situ and photo-surrogate path-riding environments among the general population in Perth, Western Australia. The findings indicate that there are specific experiential design aspects related to the riding environment, surrounding landscape or associated features that can directly influence a person’s decision to use a particular path, trail or route. The research also identified preferred communication strategies and found deficiencies in the current design process that if addressed, could lead to the development of better received and patronised riding environments. It is intended that the outcome of this research will be to provide a design framework to guide path and trail planners in the development of facilities that enhance the overall riding experience. A number of agencies responsible for developing bicycle infrastructure, or design standards, have indicated a desire to access parts of this research project for use in the decision-making process, thus achieving a better balance between safety, functional and experiential aspects

Disentanglement of Syntactic Components for Text Generation

Modelling human generated text, i.e., natural language data, is an important challenge in artificial intelligence. A good AI program should be able to understand and analyze natural language, and generate fluent and accurate responses. This standard is seen in applications of AI for natural language like machine translation, summarization, and dialog generation, all of which require the above ability. This work examines the application of deep neural networks for natural language generation. We explore how graph convolutional networks (GCNs) can be paired with recurrent neural networks (RNNs) for text generation. GCNs have the advantage of being able to leverage the inherent graphical nature of text. Sentences can be expressed as dependency trees, and GCNs can incorporate this information to generate sentences in a syntax-aware manner. Modelling sentences with both dependency trees and word representations allows us to disentangle the syntactic components of sentences and generate sentences while fusing parts of speech from multiple sentences. Our methodology combines the sentence representations from an RNN with that of a GCN to allow a decoder to gain syntactic information while reconstructing a sentence. We explore different ways of separating the syntax components in a sentence and inspect how the generation operates. We report BLEU and perplexity scores to evaluate how well the model incorporates the content based on its syntax from multiple sentences. We also observe, qualitatively, how the model generates fluent and coherent sentences while assimilating syntactic components from multiple sentences
