Healthcare is one of the largest business segments in the world and is a critical area for future growth. In order to ensure efficient access to medical and patient-related information, hospitals have invested heavily in improving clinical mobile technologies and spread their use among doctors. Notwithstanding the benefits of mobile technologies towards a more efficient and personalized delivery of care procedures, there are also indications that their use may have a negative impact on patient-centeredness and often places many cognitive and physical demands on doctors, making them prone to make medical errors. To tackle this issue, in this paper we present the main outcomes of the project TESTMED, which aimed at realizing a clinical system that provides operational support to doctors using mobile technologies for delivering care to patients, in a bid to minimize medical errors. The system exploits concepts from Business Process Management on how to manage a specific class of care procedures, called clinical guidelines, and how to support their execution and mobile orchestration among doctors. As a viable solution for doctors' interaction with the system, we investigated the use of vocal and touch interfaces. User evaluation results indicate a good usability of the system.

Audio recordings and the corresponding transcripts are often used as prosthetic memory (PM) after meetings and lectures. While current research is mainly developing novel features for prosthetic memory, less is known on how and why audio recordings and transcripts are used. We investigate how users interact with audio and transcripts as prosthetic memory, whether interaction strategies change over time, and analyse potential differences in accuracy and efficiency. In contrast to the subjective user perception, our results show that audio recordings and transcripts are equally efficient, but that transcripts are generally preferred due to their easily accessible contextual information. We further identified that prosthetic memory is not only used as a recall aid but frequently also consulted for verifying information that has been recalled from organic memory (OM). Our findings are summarised in a number of design implications for prosthetic memory solutions.

Popularity and affordability of mobile computers, especially tablets and smart phones, is considerably rising, providing an access capability for different user groups to various ICT services. Nevertheless, software solutions and hardware devices often seem not suitable enough for some target groups, like people with complex communication needs. In order to gain understanding of the challenges for usability and accessibility requirements gathering for ICT services for aided augmentative and alternative communication (AAC), this paper presents directions towards building usability requirements taxonomy for mobile AAC services. Analysis of influential factors for building proper requirements specification for an AAC service is given. Outlines for new paradigm of so-called augmentative requirements engineering (ARE) are presented, demanding holistic view on service requirements concerning users abilities and needs, service domain and associated intermediary users.
