The Way

Hedonic utility scale is a user experience (UX) evaluation method that, through a questionnaire, collects the hedonic and utilitarian dimensions of a product by rating items belonging to each dimension. In this chapter, it is proposed to adapt this method for its application with blind users using the Google TalkBack tutorial as a case study. Based on Nielsen's heuristics, five blind users rated the tutorial after completing each of its five tasks. To ensure inclusiveness in the adaptation of the method, this could be answered verbally and with the use of cards written in Braille, while, for questions of practicality in the evaluation, the number of items was reduced as well as changed the way of scoring (scale and equations) with respect to the original HED/UT. The scale of grades was ranked from 1 (very little) to 5 (quite), getting TalkBack scores between 4 and 5. The results show that the TalkBack tutorial is generally well accepted and well rated by users in both dimensions (hedonic and utility).

Interface Adaptation

AbstractAdapting the user interface of a software system to the requirements of the context of use continues to be a major challenge, particularly when users become more demanding in terms of adaptation quality. A considerable number of methods have, over the past three decades, provided some form of modelling with which to support user interface adaptation. There is, however, a crucial issue as regards in analysing the concepts, the underlying knowledge, and the user experience afforded by these methods as regards comparing their benefits and shortcomings. These methods are so numerous that positioning a new method in the state of the art is challenging. This paper, therefore, defines a conceptual reference framework for intelligent user interface adaptation containing a set of conceptual adaptation properties that are useful for model-based user interface adaptation. The objective of this set of properties is to understand any method, to compare various methods and to generate new ideas for adaptation. We also analyse the opportunities that machine learning techniques could provide for data processing and analysis in this context, and identify some open challenges in order to guarantee an appropriate user experience for end-users. The relevant literature and our experience in research and industrial collaboration have been used as the basis on which to propose future directions in which these challenges can be addressed.

Adaptive User Interface

A large number of blind people use smartphone-based assistive technology to perform their common activities. In order to provide a better user experience the existing user interface paradigm needs to be revisited. A new user interface model has been proposed in this paper. A simplified, semantically consistent, and blind-friendly adaptive user interface is provided. The proposed solution is evaluated through an empirical study on 63 blind people leveraging an improved user experience in performing common activities on a smartphone.

<p>This article presents a case study exploring the use of a student Coding Camp as a bottom-up mobile design process to generate library mobile apps. A code camp sources student programmer talent and ideas for designing software services and features.  This case study reviews process, outcomes, and next steps in mobile web app coding camps. It concludes by offering implications for services design beyond the local camp presented in this study. By understanding how patrons expect to integrate library services and resources into their use of mobile devices, librarians can better design the user experience for this environment.</p>
