体感交互在大型触摸屏环境中的应用与研究

大型触摸屏环境带来高沉浸感的触控体验,然而当用户离大屏幕过近时体验效果欠佳。为改善其交互体验,引入体感交互技术,基于用户与屏幕的距离提出2种交互模式。通过设计并实现一套测试系统,将体感交互技术应用到大型触摸屏环境中。利用该系统进行用户测试,并对测试结果进行统计学分析。测试结果显示,体感交互技术能有效减少大型触摸屏环境体验效果欠佳的局限性。体感交互技术与大型触摸屏环境的结合有利于改善公共空间的交互体验。     

基于视觉的投影- 摄像机指尖触控系统

文章提出了一种基于视觉的投影交互方法,通过判断用户手指与其在屏幕上投射阴影的融合程度来检测投影屏幕上是否有触控事件发生。为提升系统的鲁棒性,在检测阶段,将手指与其阴影同时从相机图像中分割出来,进而采用一种线性模型判断方法来判定手指与其阴影的融合程度,如果判定触碰事件发生,则通过指尖位置检测来判断触控的具体位置。该方法不需要用户使用任何辅助工具,即可用手指在投影屏幕上直接与显示画面实现交互操作。

悬浮触控 隔空操作不是梦

诺基亚手机新采用的超敏感触摸屏让人眼前一亮。可是你知道么,其实有一种更神奇的触控技术在等待我们去开发。到了冬天,在街上玩手机的人明显减少了,因为谁也不愿意在寒冷的空气中光着双手操作手机。所以诺基亚在新的手机上采用了超敏感触摸屏,这给人们戴着手套操作手机带来了希望。可是戴上厚厚的手套,手指变粗,按键的准确率会明显降低,有没有一种更先进的触摸技术来解决呢?那就来见识一下悬浮触控技术吧,有了它,隔空操作不再是梦想!提到悬浮触摸,很多人会想到索尼的智能手机,正是由于它最早使用了这项技术,才让用户手指在不接触手机屏幕的情况下可以对手机进行触摸操作。

基于微型投影仪的人机交互系统

传统操作的鼠标模式使得操作者被限制在屏幕面前一定距离且动作受到拘束,破坏了体验感。本论文进行的是一种可将任意界面经过投影变成一块虚拟触摸屏的光触感受的探索。实现了一种概念性的新型界面交互体验。用户能够利用光触控技术,像在其他手持设备上那样方便的与信息浏览内容进行交互。将来主要应用领域为公共社交场所中娱乐交互,智能家居以及展览展示场所如图书馆,博物馆,文化馆等。     

更直观的触控操作

几年前，美国科幻大片中经常出现这样一个场景：星际舰长用手指点了下屏幕，于是星际图、航线坐标等都统统一览无遗。没想到，如今触控技术的使用已经非常普遍，酷酷的人机交互界面更令人耳目一新。有了触控技术，人们只需要将指尖直接碰触到需要按的位置，便可按照指令完成操作。因此，手指就彻底代替了传统的鼠标，有的触摸屏还能在屏幕上模拟出软键盘，更是方便了文字的输入。

IT in teacher training in France

Abstract To understand what is going on in France at the moment in the domain of computers and related communication technologies in teacher training, there are two major developments that have to be kept in mind. Firstly, the ways of becoming a teacher in France underwent major changes in 1991. It is therefore too early to come to general conclusions about the effects of this reform in the field of new information technologies. Secondly, French IT in schools policy has shifted from a large-scale centralized equipment operation, which provided microcomputers in each school from 1985 to 1987, to a more regional management of equipment funding, with less national piloting in the field. This paper describes what happened during the previous period and what is taking place now. With matters still evolving the paper represents a snapshot rather than an exhaustive survey; such a survey remains to be done.     

Informatics in teacher education in Japan

Abstract This paper charts the developments in information technology (IT) policies in education in Japan over the past decade with particular emphasis on the impacts on teacher education. Beginning with the work of the National Council on Educational Reform in 1985, the Japanese education system initiated a thorough analysis of the role of information technology in all aspects of education from kindergarten through to high school, vocational education and pre- and in-service teacher education. The various approaches culminated in guidelines and statutory requirements relating to both schools' curricula and teacher training, published in the period 1990–1992. More recently other ministries have contributed to developments including the Ministry for International Trade and Industry which has categorized the different types of information engineers and among these is the new Educational Engineer. The paper reports the processes leading to these developments.     

IT in teacher education in Denmark

Abstract As with many European countries Denmark is experiencing change in teacher education and most notably in the wake of an act of government in 1992 which was designed to set out common aims for teacher education. Prior to that the content and structure of teacher education had been highly specified including, for example, the requirement that student teachers should take a course of 42 hours IT-related lessons. This paper provides a brief history of the background to the changes in teacher education and focuses on the implications that the more flexible aims for teacher education have for the future integration of IT in teacher education.     

Teacher education in IT in Germany

Abstract In 1988 the eleven West-German Kultusminister , with responsibility for the school systems in their respective Bundeslaender , reached agreement with the Federal Ministry of Education and Science on the broad concept of 'Information and Communications Technology', ITG. After four years of discussion it was agreed that ITG should be introduced into the secondary level of the general schools. In spite of strong disagreements about the ways and speed of implementation, and after several years of experiments, important parts of the concept have become a reality in practically all of the old Bundeslaender. While acknowledging the complexity of the German educational system the paper attempts to outline the development of the concept of Information and Communications Technology and its consequences in teacher education. The development in the eastern part of Germany, the former GDR, has been completely different to that in the western part and this is also commented upon in the paper.

IT in teacher education in Scotland

Abstract This paper outlines the consensual approach to the formulation of curriculum policy in general, and in relation to information technology (IT) in particular, in Scotland. It outlines the approaches to IT that have emerged as a result. These are founded on the premises that all children should develop knowledge and understanding about IT and skills in using IT; that IT should influence both content and delivery of the curriculum; and that IT (computing studies in Scotland) should be an elective for secondary school pupils. Against this background, the paper describes the evolution of policy and practice relating to IT in teacher education. It appraises the strategies which institutes are using for developing the professional skills necessary to deliver IT in the Scottish curriculum. It notes significant progress but highlights the need to develop strategies which integrate IT more deeply with other professional studies so that student teachers develop deeper, more reflective approaches to IT.     

Recent developments in ergonomics in China

Ergonomic thought and practice were introduced in ancient China in relation to modern developments in Chinese ergonomics. Despite the ten-year interruption of the 'cultural revolution’ in the late 1960s and 1970s, ergonomics has made great progress in China in the last decade. In this paper some general developments in recent ergonomics’ teaching and in professional organizations are described. Four major areas of ergonomics research are illustrated: (1) Visual displays and signal design; (2) Human-computer interface with Chinese computers; (3) Cognitive strategies and decision support; (4) Mental workload and occupational stress. The main characteristics of Chinese ergonomics are discussed and new directions are highlighted, based on recent developments and progress.
