“…The authors present an empirical study using two different scenarios to measure the effect of context location in different usability attributes such as satisfaction, learnability, efficiency, and ease of use among others. As mobility introduces new scenarios that should cover the complexity of mobile contexts, new usability guidelines are necessary to support the requirements of mobile applications apps 32 and multimodal interaction like using speech recognition 33 and new navigation facilities and location aware services. Most of the usability studies mentioned analyses the impact of usability features for the design of usable interfaces but only few works address the implementation and evaluation of concrete usability mechanisms.…”

Usability implications in software architecture: The case study of a mobile app

Usability is a highly desired but often ignored software quality. Effective user interfaces tend to increase learnability, effectiveness and user satisfaction. But usability is often neglected in the early stages of software development and is thus frequently not address in a system's architectural design. Furthermore, because usability is often neglected or deferred, it is difficult to estimate the effort specifically spent on adding or improving usability mechanisms in the software architecture and in code. In this work, we present a case study where we analyze the impact of introducing a variety of usability mechanisms to a mobile application and we report on the architectural changes that must be made in the software architecture to accommodate them. We also report on the additional code required to implement these usability mechanisms and we investigate the users' satisfaction of combining and using several usability mechanisms in a mobile application. Finally, we evaluated user responses—both positive and negatives—to these usability mechanisms via a questionnaire involving 25 users from different roles and different organizations and including contextual interviews to analyze the qualitative responses of the subjects. Our results show that apart from the relatively modest modeling and coding effort, the combination of several usability mechanisms seems beneficial for users of mobile systems and increases the satisfaction during the interaction with the system.

“…Another limitation to mobile devices is the diffi culty of data entry in fi eld work. To overcome this limitation, Kondratova and Goldfarb (2006) explored the use of speech recognition technology on mobile devices in order to improve the usability of mobile applications. The combination of voice XML and XHTML will enable the human voice to be the input in mobile applications.…”

A number of methods and measures have been used by researchers in software evaluation. Usability metrics is one of the approaches that has been used as a guideline to evaluate the quality of the system in many mobile applications. However, the metrics used for evaluation method keep changing due to new inventions of mobile phones. Thus, there is a need to create a dynamic model for evaluation that can grow together with new inventions and technology. In this paper, a dynamic usability metrics model for evaluation of mobile applications was designed. The model comprises usability goals, questions and metrics for evaluation of applications on mobile phones. To ensure that the model is reliable and effective, a usability study was conducted on two applications installed in different mobile phones. This model proves to be applicable for evaluation of mobile phone applications whereby its questions and metrics can be dynamically changed accordingly to comply with the requirements of the evaluators.

“…The student will be able to enter field notes in the forms using a portable keyboard or a pen, if appropriate or via voice input during field data gathering. In addition to this, freeform verbal field notes could be attached to the data collected as an audio file and later analyzed in class [20].…”

Abstract. This paper discusses issues associated with improving usability of user interactions with mobile devices in mobile learning applications. The focus is on using speech recognition and multimodal interaction in order to improve usability of data entry and information management for mobile learners. To assist users in managing mobile devices, user interface designers are starting to combine the traditional keyboard or pen input with "hands free" speech input, adding other modes of interaction such as speech-based interfaces that are capable of interpreting voice commands. Several research studies on multimodal mobile technology design and evaluations were carried out within our state-of the art laboratories. Results demonstrate feasibility of incorporating speech and multimodal interaction in designing applications for mobile devices. However, there are some important contextual constrains that limit applications with speech-only interfaces in mobile learning, including social and environmental factors, as well as technology limitations. These factors are discussed in detail.
