The ability of eye-tracking metrics to classify and predict the perceived driving workload

Traffic safety is directly related to the mental and physical condition of the driver. Performing regular secondary tasks while driving is an additional activity that dissipates attention and adds to the drivers' workload. Identifying driver fatigue and workload based on gaze behavior is one way to ensure a safe driving experience. The purpose of this paper is to classify and predict driving perceived workload using a set of eye-tracking metrics (gaze fixation, duration, pointing, and pupil diameter). The ability of eye-tracking metrics to predict driving workload has been investigated. As a result, frustration, performance, and temporal load showed a correlation with gaze metrics. Gaze point, duration, fixation, and pupil diameter significantly influence driving workload.Relevance to industry: Results will supply the specialists in eye-tracking/sensor technologies and traffic safety with new knowledge to improve the design of the driving performance and safety monitoring systems and efficiency of the driving process.     

Affective interaction: Using emotions as a user interface in games

Affective computing, as a novel paradigm, adds a new feature into the human-computer interactions era that brings emotions into the process of design and evaluation. Such condition influences digital games’ not only structural dimension but also content and evaluation areas. This study aims to evaluate the effect of using emotions in the form of facial expressions as a User Interface (UI) and the input of a system in virtual scenarios. After studying the findings and methods of previous researches, a conceptual framework for Affective User Interface Design and Evaluation (AFFUIDE) has been proposed. Then, a game in the genre of shoot ‘em up (called Facial Battle) in four interaction modes has been developed. The evaluation of this study has been performed in terms of the players’ performance and experience. For this purpose, 18 male students of the Multimedia Faculty of Tabriz Islamic Art University took part in the experiments, who were asked to play all four modes of the game. Then, after analyzing the normalization of collected data, one-way ANOVA and U Mann Whitney tests were used for the statistical analysis. The findings indicate that the Traditional UI is the most usable and the Full Affective UI has the best sense of fun and user experience among other methods. However, the hybrid mode (affective shooting), is not only usable as traditional mode, but it also works better in terms of user experience compared to other modes.

     

User interface design assistance for large-scale software development

The User Interface Design Assistant (UIDA) addresses the specific design problems of style and integration consistency throughout the user interface development process and aids in the automated feedback and evaluation of a system's graphical user interface according to knowledge-based rules and project-specific design examples. The UIDA system is able to quickly identify inconsistent style guide interpretations and UI design decisions resulting from distributed development of multiple UI sub-systems. This case arises when each sub-system conforms to the general style guide rules, but when integrated together, may appear inconsistent.This work was conducted jointly at the University of Southern California's Center for Software Engineering, and the Arcadia Project, University of California Irvine.     

一种基于Web的服务组装构件模型(英文)

基于web的服务组装正成为一种流行的组装风格。许多已有的工作提出将服务业务逻辑和用户界面封装为一个基于web的服务构件,并在基于web的环境中组装这些构件。这些构件模型在复用,尤其是构件验证、适配以及复合构件的支持方面仍存在许多局限。提出一种新型构件模型以支持基于web的服务组装。首先,该构件模型将用户界面和服务业务逻辑分离以获得更好的适配性;其次,开发人员不仅可以在业务逻辑的层次组装这些构件,还可以在用户界面的层次进行组装。该构件模型支持实时组装以实现及时、有效的验证和适配,同时还支持将组装结果发布为一个新的可复用的服务构件。     

Framework and authoring tool for an extension of the UIML language

This paper presents a framework for the design of User Interfaces (UIs). By applying model transformations, the framework allows different UIs to be generated for different computing platforms. The tool presented in this work helps designers to build an abstract user interface which is later transformed into a concrete user interface by means of transformation techniques based on graph grammars. These techniques can be used to generate implementation code for several UI platforms including desktop applications, dynamic websites and mobile applications. The generated user interfaces are integrated with a multi-tier application by referencing external services and communicating with the application core over Web Service protocols. Our tool also allows the concrete interfaces to be enhanced before generating the final UI. The approach uses an adaptation of UIML (User Interface Markup Language). The adaptation focuses on defining a data model and a services model, and it also introduces a navigation model that allows data communication from one UI to another. The obtained UIs together with Web Services can conform complete applications instead of just being prototypes.

Unifying Functional User Interface Design Principles

ABSTRACT

Many designers and User Interface (UI) educators discuss principles to be followed when designing the functional aspects of a UI. However, many UI principles have been proposed, scattered in scientific papers and teaching books. Some principles are different, and many are somehow similar or overlapping with others. This makes it very difficult to comprehend where to pay attention to when designing a UI. In this paper, we perform a systematic literature review to first identify the most relevant authors in the domain of functional UI design principles. Focusing on the three most cited works of these authors, we extracted 257 principles. We next analyzed all these principles, unified their variants, and, considering their scientific influence, finally derived a shorter and core selection of 36 principles. This core selection provides educators and UI designers with a clear path to teach, evaluate, learn and improve the UI functional design.

中看与中用——试析软件界面中可用性与美感之关系

可用性是当前评价用户界面的一个重要标准,它与用户体验相关。美感有助于营造良好的用户体验,有助于帮助用户完成任务,减轻压力,保持注意力和做出正确的决策。美观的界面更有吸引力,有助于产品的视觉识别,有助于企业创造文化价值和提升核心竞争力。设计人员有时面对着美观和功能的取舍,此时不仅应该寻找平衡更应该寻求新的更巧妙的解决方案。     

Automated wireless video surveillance: an evaluation framework

In the past years, surveillance systems have attracted both industries and researchers due to its importance for security. Automated Video Surveillance (AVS) systems are established to automatically monitor objects in real-time. Employing wireless communication in an AVS system is an attractive solution due to its convenient installation and configuration. Unfortunately, wireless communication, in general, has limited bandwidth, not to mention the intrinsic dynamic conditions of the network (e.g., collision and congestion). Many solutions have been proposed in the literature to solve the bandwidth allocation problem in wireless networks, but much less work is done to design evaluation frameworks for such solutions. This paper targets the demand for a realistic wireless AVS system simulation framework that models and simulates most of the details in a typical wireless AVS framework. The proposed simulation framework is built over the well-known NS-3 network simulator. This framework also supports the testing and the evaluation of cross-layer solutions that manages many factors over different layers of AVS systems in the wireless 802.11 infrastructure network. Moreover, the simulation framework supports the collection of many used performance metrics that are usually used in AVS system performance evaluation.

EISEval,a generic reconfigurable environment for evaluating agent-based interactive systems

The evaluation of interactive systems has been an active subject of research for many years. Many methods have been proposed, but most of them do not take the architectural specificities of an agent-based interactive system into account, nor do they focus on the link between architecture and evaluation. In this paper, we present an agent-based architecture model for interactive systems. Then, based on this architecture, we propose a generic, reconfigurable evaluation environment, called EISEval, designed and developed to help evaluators analyze and evaluate certain aspects of interactive systems in general and of agent-based architecture interactive systems in particular: User Interface (UI), non-functional properties (e.g., response time, complexity) and user characteristics (e.g., abilities, preferences, progress). System designers can draw useful conclusions from the evaluation results to improve the system. This environment was applied to evaluate an agent-based interactive system used to supervise an urban transport network in a study organized in laboratory.
