Distinguishing Features

There is evidence that user-centred development increases the user-friendliness of resulting products and thus the distinguishing features compared to products of competitors. However, the user-centred development requires comprehensive software and usability engineering skills to keep the process both cost-effective and time-effective. This paper covers that problem and provides insights in so-called user-centred prototyping (UCP) tools which support the production of prototypes as well as their evaluation with end-users. In particular, UCP tool called MoPeDT (Pervasive Interface Development Toolkit for Mobile Phones) is introduced. It provides assistance to interface developers of applications where mobile phones are used as interaction devices to a user’s everyday pervasive environment. Based on found tool features for UCP tools, a feature study is described between related tools and MoPeDT as well as a comparative user study between this tool and a traditional approach. A further focus of the paper is the tool-supported execution of empiric evaluations.

In the last years, researchers are exploring the feasibility of visual language editors in domain-specific domains where their alleged user-friendliness can be exploited to involve end-users in configuring their artifacts. In this chapter, the authors present an experimental user study conducted to validate the hypothesis that adopting a visual language could help prospective end-users of an electronic medical record define their own document-related local rules. This study allows them to claim that their visual rule editor based on the OpenBlocks framework can be used with no particular training as proficiently as with specific training, and it was found user-friendly by the user panel involved. Although the conclusions of this study cannot be broadly generalized, the findings are a preliminary contribution to show the importance of visual languages in domain-specific rule definition by end-users with no particular IT skills, like medical doctors are supposed to represent.

Nowadays, mobile phones provide not just voice call and messaging services, but plethora of other services. Those computational capabilities allow mobile phones to serve people in various areas including education, banking, commerce, travelling, and other daily life aspects. Meanwhile, the number of mobile phone users has increased dramatically in the last decade. On the other hand, the usability of an application can usually be verified through the user interface. Therefore, this paper aims to design a measurement tool to evaluate the usability of mobile applications based on the usability attributes and dimensions that must be considered in the interface. To obtain the appropriate attributes, a Systematic Literature Review (SLR) has been conducted and the Goal Question Metric (GQM) has been used to design the tool. From 261 related works only 18 most relevant ones were selected, through four SLR. 25 dimensions were found through the SLR, but some of these dimensions are synonymous or a part of other dimensions. Consequently, three dimensions must be included in any usability evaluation instrument, which is broken down into ten sub dimensions.

Delivering aphasia therapy via telecommunication may provide a means to deliver intensive therapy in a cost-effective way. Teletherapy, remotely-administered (language) treatment, may support the repetitive drill practices that people with chronic aphasia need to perform when learning to compensate for their lasting language difficulties. The use of teletherapy may allow speech and language pathologists (SLPs) to focus in-person sessions more strongly on the generalisation of therapy effects to daily life. This single subject study is an investigation whether a teletherapy application called e-REST meets the criteria of accessibility, user-friendliness, as well as effectiveness. e-REST, the teletherapy version of the Dutch and adapted Reduced Syntax Therapy, teaches chronically aphasic speakers of Dutch who experience difficulties in sentence production to convey their messages in a kind of telegraphic style. The results obtained suggest that it is reasonable to conduct a larger study into the user-friendliness, accessibility, effectiveness, and cost-effectiveness of e-REST.

The mobile applications industry has had significant growth in the last few years. Mobile phones are everywhere since we use them in every part of our daily lives for entertainment, communication and other various uses. Unfortunately, there was also a substantial increase the number of autism cases in kids around the world, which has prompted for a dire need of a therapy method that is cheap, reliable and accessible for everyone who needs it. Researchers have tried several methods, like robotics and virtual reality, to help in the therapy of autistic children. While their results were promising, these technologies are still out of reach of most users due to their high cost. Mobile phones, however, are much more accessible since everyone has one, and they have a wide array of useful gadgets that can be used in making the therapy sessions more engaging and fun such as cameras, accelerometers, speakers, microphones and others. This project aims to design and implement an interactive learning environment based on a mobile application for teaching kids with special needs.

Introduction: Laparoscopic surgery is an established treatment modality worldwide. Opportunities to acquire this skill using expensive simulation at workplace are not always feasible due to cost, time and accessibility constraints. Nep-Endotrainer is a cost effective homemade laparoscopic simulation tool built in Nepal. Methods: Nep-Endotrainer was built using plastic manikins easily available in market. Nine apertures were created with a drilling machine, four on each side of umbilicus and one at the epigastric region. These apertures were covered by thick piece of rubber of vehicle tire with apertures in them. Logitech® C270 HD webcam was fixed interiorly with metal screws. The base of the manikin was fixed to a wooden board with hinge joint. Five different interchangeable training modules were assembled in 10×10 cm2 size wooden boards. The LED light was fixed interiorly near the web camera. The camera USB can be easily connected with laptops, tablets and mobile phones. We used discarded hand instruments from laparoscopic centers to reduce the cost of the endotrainer. Conclusion: Nep-Endotrainer is accessible to any personal budget and can be readily constructed. It allows more frequent practice at home, outside the venue and hours of surgical departments.

With a renewed global focus on anti-submarine warfare (ASW), the United States Navy will increasingly rely on unmanned underwater vehicle (UUV) technology to serve as a cost-effective force multiplier. Modern UUV development necessitates a uniquely constrained, iterative approach to the traditional submarine design spiral. Considering a broad spectrum of customer-generated requirements, the UUV conceptual design process applies the best practices of naval architecture, marine engineering, ocean engineering, systems engineering, and submersible design. This paper provides an assessment of the traditional approach to the UUV design and development process. Specifically, this paper analyzes the design philosophy for modern UUVs, provides a design framework for the UUV conceptual design process, and details specific recommendations to encourage innovation in the subsea realm.

Mobile Phone Applications

In this chapter, we discuss the importance of evaluating the usability of mobile applications using tools and technics that consider their specific characteristics. One common way to evaluate usability is using heuristics. However, since many assumptions regarding usability of computer applications are not true for mobile applications, a question arises: does there exist usability heuristics specific for this type of device? To answer this question, we conducted a systematic literature review. We mapped the encountered sets of heuristics to Nielsen's ten heuristics and identified additional ones specifically proposed for this kind of device. Our review indicates that research with respect to usability heuristics for mobile phones are still sparse. Nevertheless, this chapter provides an overview on the state of the art that can guide the design and evaluation of interfaces for mobile applications as well as provide a starting point for the evolution of such customized heuristics.
