“…Currently, there is an ongoing generalized discussion regarding the advantages and disadvantages of testing software in the laboratory [39] as opposed to when the development cycle is over [40]. This study considers that these two approaches are complementary, and must be applied according to the user's needs and intended context of use.…”

An Agile Approach to Improve the Usability of a Physical Telerehabilitation Platform

The goal of a telerehabilitation platform is to safely and securely facilitate the rehabilitation of patients through the use of telecommunication technologies complemented with the use of biomedical smart sensors. The purpose of this study was to perform a usability evaluation of a telerehabilitation platform. To improve the level of usability, the researchers developed and proposed an iterative process. The platform uses a digital representation of the patient which duplicates the therapeutic exercise being executed by the patient; this is detected by a Kinect camera and sensors in real time. This study used inspection methods to perform a usability evaluation of an exploratory prototype of a telerehabilitation platform. In addition, a cognitive workload assessment was performed to complement the usability evaluation. Users were involved through all the stages of the iterative refinement process. Usability issues were progressively reduced from the first iteration to the fourth iteration according to improvements which were developed and applied by the experts. Usability issues originally cataloged as catastrophic were reduced to zero, major usability problems were reduced to ten (2.75%) and minor usability problems were decreased to 141 (38.74%). This study also intends to serve as a guide to improve the usability of e-Health systems in alignment with the software development cycle.

“…The question of which research setting is optimal for studying mobile usability has been addressed in earlier studies (Kjeldskov, Skov, Als, & Høegh, 2004;Kaikkonen, Keklinen, Cankar, Kallio, & Kankainen, 2005;Nielsen, Overgaard, Pedersen, Stage, & Stenild, 2006;Rogers et al, 2007). The studies, however, offer different views.…”

Fidelity Considerations for Simulation-Based Usability Assessments of Mobile ICT for Hospitals

Controlled laboratory-based usability assessments of mobile information and communications technologies (ICT) for hospitals have been conducted. As part of these assessments, clinicians have acted out mobile work scenarios and used the systems to solve related tasks. The evaluations show that relevant usability issues go beyond those of graphical user interfaces. Many of these usability issues only show up when the real-world context of use is replicated in the laboratory to a high degree of fidelity. The complexity of the context of use for mobile ICT in hospitals has motivated us to explore training simulation fidelity theories. Based on a review of the training simulation literature, a set of fidelity dimensions through which training simulations are often adjusted to meet specific goals are identified. It is argued that the same mechanisms can be used in usability assessments of mobile ICT for hospitals. Our argument is substantiated by using the identified set of fidelity dimensions in a retrospective analysis of two usability assessments. The analysis explains how the configuration of fidelity dimensions, each reflecting various degrees of realism vis-à-vis the actual performance context, contributed to the identification of relevant usability issues.

“…In some cases there has been little difference in results (e.g., Sun and May 2013]). Others understandably disagree (e.g., [Nielsen et al 2006]). Furthermore, while we have been successful in achieving similar results between diverse groups when focusing on audio and the readability of a foreign language, clearly there are many elements of field studies it is not possible to mimic -for example, differences in power dynamics, cultural etiquette, comfort with technology and so on [Medhi et al 2010].…”

Exploring Low-Cost, Internet-Free Information Access for Resource-Constrained Communities

Rural developing regions are often defined in terms of their resource constraints, including limited technology exposure, lack of power and low access to data connections (leading to an inability to access information from digital or physical sources), as well as being amongst the most socioeconomically disadvantaged and least literate in their countries' populations. This paper is focused around information access in such regions, aiming to build upon and extend the audio-based services that are already widely used in order to provide access to further types of media. In this article, then, we present an extended exploration of AudioCanvasan interactive telephone-based audio information system which allows cameraphone users to interact directly with their own photos of physical media to receive narration or description. Our novel approach requires no specialist hardware, literacy, or data connectivity, making it far more likely to be a suitable solution for users in such regions.
