PURPOSE To identify factors that determine patients' intentions to use point-of-care medical devices, ie, portable coagulometer devices for self-testing of the international normalized ratio (INR) required for ongoing monitoring of blood-coagulation intensity among patients on long-term oral anticoagulation therapy with vitamin K antagonists, eg, warfarin.(More)
BACKGROUND The increasing pervasiveness of mobile technologies has given potential to transform healthcare by facilitating clinical management using software applications. These technologies may provide valuable tools in sexual health care and potentially overcome existing practical and cultural barriers to routine testing for sexually transmitted(More)
Emerging technologies, such as affective computing, have potential to enhance human-computer interaction (HCI). They are still at a prototype stage and effective working systems are still some years off. The problem is that much development is driven by what is technically possible at this time, rather than by what users require. By using Wizard-of-Oz (WOZ)(More)
A bidirectional optimizing approach for the melting spinning process based on an immune-enhanced neural network is proposed. The proposed bidirectional model can not only reveal the internal nonlinear relationship between the process configuration and the quality indices of the fibers as final product, but also provide a tool for engineers to develop new(More)
There is now growing interest in the development of computer systems which respond to users " emotion and affect. We report three small scale studies (with a total of 42 participants) which investigate the extent to which affective agents, using strategies derived from human-human interaction, can reduce user frustration within human-computer interaction.(More)
In 2000 Hone and Graham [4] published 'Towards a tool for the subjective assessment of speech system interfaces (SASSI)'. This position paper argues that the time is right to turn the theoretical foundations established in this earlier paper into a fully validated and score-able real world tool which can be applied to the usability measurement of current(More)
BACKGROUND Despite considerable international eHealth impetus, there is no guidance on the development of online clinical care pathways. Advances in diagnostics now enable self-testing with home diagnosis, to which comprehensive online clinical care could be linked, facilitating completely self-directed, remote care. We describe a new framework for(More)
OBJECTIVE Seeking sexual health information online is common, and provision of mobile medical applications (apps) for STIs is increasing. Young people, inherently at higher risk of STIs, are avid users of technology, and apps could be appealing sources of information. We undertook a comprehensive review of content and accuracy of apps for people seeking(More)
BACKGROUND Control of sexually transmitted infections (STI) is a global public health priority. Despite the UK's free, confidential sexual health clinical services, those at greatest risk of STIs, including young people, report barriers to use. These include: embarrassment regarding face-to-face consultations; the time-commitment needed to attend clinic;(More)
