Towards a Library of Workflow User Interface Patterns

A collection of user interface design patterns for workflow infor ma tion systems is presented. Each Workflow User Interface Pattern (WUIP) is characterized by properties expressed in the PLML markup language for expressing patterns and augmented by additional attributes and models at tached to the pattern: the abstract user interface and the corresponding task model. These models are specified in a User Interface Description Langua ge. All WUIPs are stored in a library and can be retrieved within a workflow editor that links each workflow pattern to its corresponding WUIP, thus giving rise to a user interface for each workflow pattern. The software then gathers these UIs and the ones corresponding to workflow tasks into a user interface flow, a new concept introduced for specifying the intertwining of interfaces used by workers and the workflow manager in a single workflow.

Advance human---machine interface automatic evaluation

The need for accessibility evaluation tools is motivated by several endogenous and exogenous reasons coming from the end user (the designer and the developer) and companies releasing information systems. Existing evaluation tools mainly concentrate on examining the code of Web pages: Web pages more and more frequently contain non-HTML parts that entirely escape from being treated by existing techniques. This is the case of the advanced human–machine interface (AHMI), a piece of software programmed in C/C++, used for controlling the advanced flight management system in the aircraft cockpit. Studying this new user interface (UI) requires a structured approach to evaluate and validate AHMI designs. The goal in this work is to develop an evaluation tool to automate the process of evaluating the AHMI. The method addresses: support of multiple bases of guidelines (accessibility or usability or both) on-demand (partial or total evaluation), with different levels of details (a presentation for developers and for those responsible for certifying accessibility). The method goes a step toward the automatic evaluation of UI containing non-HTML parts.

Identification Criteria in Task Modeling

Task modeling consists of a fundamental activity that initiates usercentered design in user interface development. It is therefore important to reach the best task model possible and that the task modeling activity remains consistent when the task modeler changes. For this purpose, this paper introduces a set of criteria in order to identify tasks during task modeling in an unambiguous way that results into a task model exhibiting desired properties of quality such as completeness, consistency. In addition, starting and stopping criteria provide designers with guidance on when and how to start and finish the task modeling.

Patterns of Interaction Description Including Aspects of Constraints

Interaction patterns emerge as a solution for creating successful interactive systems, aiming mainly to solve a problem of an end-user interaction with a user interface, these patterns may be linked through the interaction pattern languages. Over time, various proposals have suggested such patterns, and its definition have been raised different formats describing patterns, in which the author is free to decide what elements or characteristics considered in its definition. This article is primarily concerned with showing how a template for defining patterns are selected. This is part of a research project that aims to propose a language interaction patterns for the design of software products focused on the user experience. To this end, it has carried out a conceptual review of some of the different formats describing patterns hitherto proposed and defined what elements or characteristics used, the findings have been compared with the application of a survey expert knowledge on the subject of patterns on the level of importance of the features found.

Structure, organization and categorization of languages of interaction patterns

Interaction pattern languages represent a solution to user-centered interface design problems. Throughout the years, different authors have dedicated their efforts to developing collections of patterns aimed at addressing usability issues. However, their authors have organized them in different ways, making it difficult to compare and transfer patterns from one language to another. This article presents a review of the state of the art of interaction pattern languages, their structure, organization and the relationships between them. Finally, it shows the adaptation of a set of interaction patterns to guarantee better results in obtaining user experience

A Production Model of Mobile Applications for Children with Learning Problems in Basic Math

This paper proposes a systematic solution through a model of software production divided into two stages: requirements and prototyping. These stages are connected in order to develop playful mobile interactive applications for children with learning problems in basic math, which are developed based on the pedagogical fundamentals of Piagets logic and infra-logic operations as well as fundamentals of software engineering.

How to Describe Workflow Information Systems to Support Business Process

This paper addresses a methodology for developing the various user interfaces (UI) of a workflow information system (WIS), which are advocated to automate business processes, following a model-centric approach based on the requirements and processes of the organization. The methodology applies to: 1) integrate human and machines based activities, in particular those involving interaction with IT applications and tools, 2) to identify how tasks are structured, who perform them, what their relative order is, how they are offered or assigned, and how tasks are being tracked. For this purpose, workflow is recursively decomposed into processes which are in turn decomposed into tasks. Each task gives rise to a task model whose structure, ordering, and connection with the domain model allows the automated generation of corresponding UIs in a transformational approach.
