由隐性记忆引导的交互设计研究

认知心理学介入到交互设计领域受到越来越多学者的关注,但是关于无意识的隐性记忆的介入却甚少被提及。,文章从隐性记忆的特征、隐性记忆介入交互设计的价值以及隐性记忆引导交互设计的应用三方面进行研究和探索,通过对目标群体用户隐性记忆的普遍性研究,找到更高效的设计来提高用户体验。     

感性的科技——浅析可穿戴设备的未来发展趋势

2013年被称为可穿戴设计元年,在发展过程中,其始终未能成为生活中的必需品,是因为忽略了最重要的两个方面：一是找到最恰当的人机交互关系;二是满足用户真正的需求。而满足了这两方面就可以帮助建立更亲密的,回归原本的,人与人之间的沟通,＂以人为本＂的理念更促进了可穿戴设计内部操作关系与外在表现形式的研究和探索。而数据背后的分析服务不仅能增强用户对于可穿戴设计更完整更智能的体验,更有利于可穿戴设计企业更长久更完善的商业发展。     

MIMO系统中基于SLNR的用户调度准则

多用户MIMO系统中,基于SLNR（signal-to-leakage-and-noise,信漏噪比）的预编码方案能够同时考虑噪声和信号泄漏问题,不但提高了系统性能,同时降低了系统的复杂度,但要求基站同时服务的数据流数之和不得大于其发射天线数. 因此,当用户数较多时,需要进行用户调度. 基于SLNR的用户调度准则只需要知道其他用户的信道信息,并能够合理的选择用户,通过仿真得知,该调度准则能够使系统获得良好的性能.     

基于人脸特征和线积分卷积的肖像素描生成

为了更好地模拟素描的笔画和突显肖像素描中五官的部分,提出基于人脸特征和线积分卷积的肖像素描生成方法.首先进行人脸分割,由人脸特征点确定GrabCut算法中每个特征的初始trimap,然后根据分割结果使用线积分卷积算法绘制肖像素描.文中使用了基于分割结果的多分辨率白噪声和方向场,并提出了基于分割结果的自适应性边界提取算法.实验结果表明,该算法改善了肖像素描的生成效果.     

Puzzle: A mobile application development environment using a jigsaw metaphor

ObjectiveCreate a visual mobile end user development framework, named Puzzle, which allows end users without IT background to create, modify and execute applications, and provides support for interaction with smart things, phone functions and web services.MethodsDesign of an intuitive visual metaphor and associated interaction techniques for supporting end user development in mobile devices with iterative empirical validation.ResultsOur results show that the jigsaw is an intuitive metaphor for development in a mobile environment and our interaction techniques required a limited cognitive effort to use and learn the framework. Integration of different modalities and usage of smart things was relevant for users.ConclusionPuzzle has addressed the main objective. The framework further contributes to the research on mobile end user development in order to create an incentive for users to go beyond consuming content and applications to start creating their own applications.PracticeUsage of a mobile end user development environment has the potential to create a shift from the conventional few-to-many distribution model of software to a many-to-many distribution model. Users will be able to create applications that fit their requirements and share their achievements with peers.ImplicationsThis study has indicated that the Puzzle visual environment has the potential to enable users to easily create applications and stimulate exploration of innovative scenarios through smartphones.     

Sharing your view: A distributed user interface approach for reviewing emergency plans

Emergency planning is an ongoing activity in which a multidisciplinary group of experts intermittently collaborate to define the most appropriate response to risks. One of the most important tasks of emergency planning is the review of plans as a way of maintaining, refining, and improving them. This review of plans is based on exchanging knowledge and experiences in order to take into account different perspectives and generate alternative solutions. An exploratory case study carried out within municipal organizations has disclosed how the application of rigid plan reviewing practices hinders team creativity and, consequently, effective decision-making. This paper presents a computer-based collaborative environment aimed at supporting unstructured team discussion during the post-hoc review of emergency plan. This collaborative environment allows emergency planning team members to share their view in a free manner by interacting with user interface components distributed across several input and output dimensions. The usage of the environment has proved how the application of new interactive technologies can create more dynamic work settings, fostering team creativity.     

基于加权语义网和有效信息的个性化用户兴趣建模*

为了提高个性化用户兴趣建模的准确率,对用户建模过程进行了优化。在计算文档相似度时,综合考虑特征词的语义关系以及在文档中的分布情况,引入加权语义网,提高了文档相似度计算精度;在计算兴趣度权值时,引入有效信息的概念及量化方法,以解决用户兴趣类权值计算过于主观的问题,并提出具体权值算法,提高了权值计算的准确性。实验结果表明,改进的方法在用户兴趣聚类和兴趣类别权值计算的准确率上都较以往方法有较大提高。     

手机人机交互界面设计趋势探究

随着技术平准化、手机产业价格竞争的环境出现,手机的人机交互界面(UI)给手机市场提供了新的卖点,同时凭借各企业固有的UI继续提高客户的忠诚度,渴望成为新的产业发展动力。手机UI的新设计与功能开发是根据各种客户群体的喜好及使用习惯而进行的。随着环境和生活方式的多样化,其开发范围和潜力正在无限扩大。这些新的趋势使得界面交互可能不再囿于某个具体产品本身与用户的互动,它可能涉及到与使用环境、其他用户之间的交流。根据对当前手机技术的分析以及对国外在人机交互及相关领域研究的关注,提出了"泛交互"的概念,并对新的趋势、新的设计进行了展望和探讨。
