Online Shopping Websites: An Evaluation of User Experience and Interface Ergonomic Criteria from the Perspective of Older Users

This paper presents a user experience evaluation of two online shopping websites from the perspective of older users (those aged 50 and older). Two online shopping websites were evaluated using methodological procedures established in prior research [1]. The methodology consists of four steps: (1) heuristic interface evaluation using an ergonomic criteria checklist, (2) online identification and experience questionnaire, (3) evaluation of user experience and interface interaction, and (4) satisfaction questionnaire. Results of the study revealed the analyzed websites are not suitable for older users, who find it difficult to interact with these interfaces.

Planejamento de cursos online para professores de alemão: parâmetros em mapa conceitual

Distance-learning language courses are gaining ground because they meet contemporary social demands and expand opportunities for access to new knowledge. They also favor interaction among people with similar goals but who live in places where no live learning arrangements are available. Taking Valente (2002), Garrison and Anderson (2000), and other authors for theoretical bases, this paper reflects on the criteria and aspects to be considered when one plans and ministers online teacher training courses. The data were taken from a distance-based university extension course offered on the Moodle learning platform by a university in the State of São Paulo, Brazil. The objective was to encourage German language teachers to further develop their own language skills, reflect on aspects of inter-culturality in teaching the target language, and provide experience with current technological resources. This paper describes the elements that proved to be relevant in the creation and planning of the course, based on authors who deal with characteristics of computer-mediated teaching. The importance of this study is related to the fact that little information is available on the planning of courses in online formats.

Sistema de recomendação de produtos online baseado em palavras-chave

This project aims to explore the many methods used for the development of recommendation systems to user ’ s items and apply the content - based recommendation method on a prototype system whose purpose is to recommend books to users. This paper exposes the most popular methods for creating systems capable of providing items (products) according to user preferences, such as collaborat ive filtering and content - based. It also point different techniques that can be applied to calculate the similarity between two entities, for items or users, as the Pearson ’s method, calculating the cosine of vectors and more recently, a proposal to use a Bayesian system under a Dirichlet distribution. In addition, this work has the purpose to go through various points on the design of an online application, or a website, dealing not only oriented algorithms issues, but also the definition of development to ols and techniques to improve the user’s experience. The tools used for the development of the page are listed, and a topic about web design is also discussed in order to emphasize the importance of the layout of the application. At the end, some examples of recommender systems are presented for curiosity , learning and research purposes
