Despite decades of research, muscle-based control of assistive devices (myocontrol) is still unreliable; for instance upper-limb prostheses, each year more and more dexterous and human-like, still provide hardly enough functionality to justify their cost and the effort required to use them. In order to try and close this gap, we propose to shift the goal of myocontrol from guessing intended movements to creating new circular reactions in the constructivist sense defined by Piaget. To this aim, the myocontrol system must be able to acquire new knowledge and forget past one, and knowledge acquisition/forgetting must happen on demand, requested either by the user or by the system itself. We propose a unifying framework based upon Radical Constructivism for the design of such a myocontrol system, including its user interface and user-device interaction strategy.

AbstractThe process of generating a stable knockout cell line is a complex process that can take several months to complete. In this work, we introduce a microfluidic method that is capable of isolating single cells, selecting successful edited clones, and expansion of these isoclones. Using a hybrid microfluidics method, droplets in channels can be individually addressed using a co-planar electrode system. In our hybrid microfluidic device, we show that we can trap single cells and subsequently encapsulate them on demand into pL-sized droplets. Furthermore, individual cells inside the droplet can be released from the traps or merged with other droplets by simply applying an electric potential to the electrodes that is actuated through a user interface. We use this high precision control to sort and to recover single isoclones to establish monoclonal cell lines, which is demonstrated with a heterozygous NCI-H1299 lung squamous cell population resulting from loss-of-function eGFP and RAF1 gene knock-out transfections.

Errors committed during healthcare providers’ use of patient controlled analgesia (PCA) systems in the acute care setting are poorly understood. A PCA is a complex, medical device that delivers a prescribed pain medication primarily through the intravenous route into the patient. The benefits of PCA use are numerous, but PCAs are also a known source of errors resulting in patient injury. Human factors usability analyses are methods to identify and mitigate factors that contribute to errors during user-device interaction. The purpose of this paper is to present the findings from an integrative review of published medical device usability analyses and to provide the foundation for future empirical research to improve our understanding of PCA system errors.

Mobile Learning also known as mLearning, is a new generation of learning where content which users wants to learn is accessible and available on mobile devices like smart phone and tablets. With the evolution of “world in the pocket” learning becomes much easier and one can start learning on the go. This paper illustrates how mLearning could be a better new way to learn and to interact with the learning content provided and how mLearning is proving to be a better alternative to traditional learning. Learning through traditional methods is not helping students to learn and gain new knowledge wherever and whenever they want and also it’s not that effective. It is also researched that not all mLearning applications are helpful for the students or learners to learn whatever they want, only apps with interactive and user-friendly user interface were found helpful. That’s why mobile learning applications are made with user-friendly user interface. Some practical strategies and methods of implementation of mLearning approach despite of its limitations and challenges were recommended in this paper as well.

New knowledge and technology brought about by globalization can be applied to revitalize local cultures in innovative ways. It can start with glocalization community design to sustain unique traditional events so as to energize the community. The paper proposes a study on designing assistive devices for exclusive palanquin carriers for a local religious event. Field investigation, questionnaire survey, and in-depth interviews were adopted to design appropriate assistive devices for palanquin carriers. This design used shoulder protectors to reduce the pain of the palanquin carriers. It is recommended that the palanquin carriers wear a shoulder protective vest with a protector applied to each shoulder to share the weight of the palanquin to maintain a good physical condition so as to facilitate the completion of the event. The task is to develop a protective vest that the palanquin carriers love to wear and will become the focus of attention in the detouring. The designed protective vest could attract more young people to participate in the event, that is how the aging problem could be solved. It is the first but important step to resolve the aging crisis of the event.

 The success of IoT technologies is undeniable. They are entering more and more in our lives, carrying out increasingly complex tasks. However, there are still a few problems we need to face and solve. For instance, it is not given that the users will be prepared to afford all the automation that IoT devices will offer or that it will be compatible with the users’ cognitive attitudes and its actual and real goals. Within this work, we start analyzing which reasons undermine the acceptance of IoT systems and then we propose a possible solution, tanking into account not just the user-device interaction, but also how this affects the device-device interaction. Since the complexity of the tasks the user asks may require the cooperation of some devices to be realized, the regulation of this relationship represents a necessary step for this technology. The first contribution of this work is the level characterization of the autonomy a user can grant to an IoT device. The second contribution is a theoretical model to deal with users and to stimulate users’ acceptance, taking also into account a possible, collaborative organizational structure, to manage the creation of groups and the partners’ selection process.

User Device

The widespread use of computing technology raises the need for interactive systems that adapt to user, device and environment. Multimodal user interfaces provide the means to support the user in various situations and to adapt the interaction to the user’s needs. In this chapter we present a system utilizing design-time user interface models at runtime to provide flexible multimodal user interfaces. The server-based system allows the combination and integration of multiple devices to support multimodal interaction and the adaptation of the user interface to the used devices, the user and the environment. The utilization of the user interface models at runtime allows exploiting the design information for advanced adaptation possibilities. An implementation of the system has been successfully deployed in a smart home environment throughout the Service Centric Home project (www.sercho.de).
