In this paper we describe some of the practical issues involved in designing, building and deploying a sensor network for oceanographic monitoring. The paper explains some of the design decisions and their consequences, and some of the lessons learned from a first sensor network trial at sea.
BACKGROUND Many eHealth technologies are not successful in realizing sustainable innovations in health care practices. One of the reasons for this is that the current development of eHealth technology often disregards the interdependencies between technology, human characteristics, and the socioeconomic environment, resulting in technology that has a low(More)
Many interactive medical devices are less easy to use than they might be, and do not fit as well as they could in their contexts of use. Occasionally, the deficiencies lead to serious incidents; more often, they have a less visible effect on the resilience and efficiency of healthcare systems. These issues remain largely invisible as they are not reported(More)
Medical devices are essential tools for modern healthcare delivery. However, significant issues can arise if medical devices are designed for 'work as imagined' when this is misaligned with 'work as done'. This problem can be compounded as the details of device design, in terms of usability and the way a device supports or changes working practices, often(More)
—The design of medical devices directly affects the way healthcare practitioners carry out their daily tasks. Users welcome design that takes into account the clinical environment, in which the device is operated and is compatible with their workflow. However, if the design fails to fit, the likelihood of errors increases, which will put patient safety at(More)
Medical devices embedded with computer systems have been widely adopted in many healthcare situations with the intention to deliver accurate and effective medication. However, due to the nature of medical devices, usability issues and the complexity of their context of use, designing and evaluating interactive medical devices from a human error management(More)
Number entry is ubiquitous in user interface (UI) design, and in many applications — such as finance, aviation, healthcare — here, mitigating errors is critical. This paper examines the effects of factors such as the type of number (e.g., integer or decimal), number length (i.e., short or long) and display position (i.e., near or far) on entry errors. Until(More)
Designing and manufacturing medical devices is a complex and specialist effort. Throughout the process, there is an opportunity to consult across those involved in various aspects of development (for example Human Factors (HF), Human Computer Interaction (HCI), Design and Manufacture). Developers report difficulties in this area, speaking of isolated team(More)
