    A Methodology for Generating Ideas to Solve Problems of the Mobility-Challenged

    No full text
    The aim of this study is to conduct root cause analysis of problems of the mobility-challenged when they walk and generate ideas to solve the problems using idea generation techniques. Finding usersโ€™ problems is important to develop new products or services which give better user experience to users. Based on collected problems, identifying causes of them is also essential to develop effective and creative products and services. There are many techniques for cause analysis and idea generation. Different techniques should be chosen depending on target users, types of product and service. This study tried to make ideas to improve the experience of the mobility-challenged when they walk outside. We choose 5W1H and Why-Why diagram as cause analysis techniques. In idea generation step, How-How diagram and SCAMPER were used. As a result, 1,055 causes were derived from 23 problems, and 146 ideas were generated using idea generation techniques. Ideas can be classified into two types by their function: providing information and aiding communication. Providing information about obstacles, other people, and mobility-challenged is included in providing information type. Ideas about translating speech, notifying and sending request are included in aiding communication type. This results of the study can be utilized to develop real product or service to improve the experience of the mobility-challenged when they walk.2

    Investigating Pedestrian Experiences of the mobility-challenged

    The aim of this study is to identify broad pedestrian experiences of the mobility-challenged. Walking is major physical activity of human, which affect health and quality of life. However, the mobility-challenged feels difficult to walk outside because of their physical and cognitive weakness. Although there are social opinions that the mobility-challenged has right to walk and attempts to make pedestrian-friendly environments, pedestrian cannot still walk outside freely. It is essential to identify experiences of the mobility-challenged while walking and support them appropriately. Diary methods and focus group interview (FGI) were selected as user survey methods to collect pedestrian experiences of the mobility-challenged. We recruited twenty-seven participants; eight visually challenged, eight aurally challenged, and eleven physically challenged. They were asked to daily write one positive and one negative experiences while walking on diary for one week. After that, they were participated in FGI. They were grouped according to type of disability. They discussed about their experiences, which are written in diaries. Discussion sessions were made by the principles of pedestrian experiences. Pedestrian experiences collected were identified as the principles of pedestrian experience. Seeing that most of the experiences were negative, it seems that the mobility-challenged usually undergoes discomforts while walking outside. To improve their pedestrian experiences, effort based on their experiences should be made from various perspectives. The experiences can be baseline data of the design guidelines for pedestrian-friendly environments. Also, they can be opportunities of developing supportive tools of the mobility-challenged.2

    This study aims to define IoT intelligence and its characteristics. Advances in the field of information and communication technology have allowed the devices to be connected to the network. It allows the users to monitor and control the devices anytime and anywhere. With the data collected by the IoT devices, it is possible to understand the behaviors and intention of the users. The devices can provide services suitable for the situation and the intention, which are called intelligent services or personalized services. Accordingly, intelligent IoT services are being developed and launched. But most are designed with a technology focus, so those are featureless and fail to provide a satisfying experience for users. To provide a better experience for the users, it is necessary to understand IoT intelligence with the user's viewpoint. This study defined IoT intelligence as a system that senses/understands the behaviors of users and their context and provides assistive services with a certain degree of autonomy and rationality in an IoT environment. And we derived its characteristics from two perspectives; IoT intelligence service types and IoT intelligence maturity levels. The results of this study can be used to develop new IoT services in the future.2
