This study aimed to evaluate how differently co-located users perform and interact while solving problems by using existing and newly developed interaction mechanisms of a multi-touch tabletop system on a large-size tabletop display. Furthermore, this study aimed to investigate users’ perceived situation awareness due to the system. This study conducted one experiment and introduced three newly developed interaction mechanisms: two-way rubber band, drag-and-response, and centre collection area. Two-way rubber band enables users not only to send but also to request digital objects. Drag-and-response allows users to accept or to reject digital objects sent by others; therefore, it eliminates conflicting situations and interference. Centre collection area stores, organises, and manages shared digital resources on a surface of a tabletop display, so that users have an overall picture of available resources. This paper discusses results of an experiment, research findings, and implications along with conclusions and several suggestions for future development and research. 相似文献

为了设计实用新型工业人机界面,提出了一种基于五点触摸校正和中位数均值滤波的Android多点触摸输入系统设计方法。采用五点触摸校正,根据触摸屏上采样的五个点,计算出校正系数,作为触屏校正参数;在mXT224控制器处理基础上,采用中位数均值阀限滤波,滤除触摸系统高斯噪声与尖峰噪声,并结合触摸校正参数校正输入坐标,逐级上传输入坐标信息,最终传递给上层应用程序。测试表明,基于优化的Android多点触摸输入系统在噪声很大环境下能够维持高信噪比(超过80∶1),并支持带手套或触笔触摸输入,反应时间小于10 ms,符合工业人机界面(HMI)设计要求。 相似文献

This study examined usability principles and interface designs in order to understand the relationship between the intentions of mobile e-book interface designs and users' perceptions. First, this study summarised 4 usability principles and 16 interface attributes, in order to conduct usability testing and questionnaire survey by referring to Nielsen (1993), Norman (2002), and Yeh (2010), who proposed the usability principles. Second, this study used the interviews to explore the perceptions and behaviours of user operations through senior users of multi-touch prototype devices. The results of this study are as follows: (1) users' behaviour of operating an interactive interface is related to user prior experience; (2) users' rating of the visibility principle is related to users' subjective perception but not related to user prior experience; however, users' ratings of the ease, efficiency, and enjoyment principles are related to user prior experience; (3) the interview survey reveals that the key attributes affecting users' behaviour of operating an interface include aesthetics, achievement, and friendliness. 相似文献

TangiWheel: A Widget for Manipulating Collections on Tabletop Displays Supporting Hybrid Input Modality 下载免费PDF全文
In this paper we present TangiWheel,a collection manipulation widget for tabletop displays.Our implementation is flexible,allowing either multi-touch or interaction,or even a hybrid scheme to better suit user choice and convenience.Different TangiWheel aspects and features are compared with other existing widgets for collection manipulation.The study reveals that TangiWheel is the first proposal to support a hybrid input modality with large resemblance levels between touch and tangible interaction styles.Several experiments were conducted to evaluate the techniques used in each input scheme for a better understanding of tangible surface interfaces in complex tasks performed by a single user (e.g.,involving a typical master-slave exploration pattern).The results show that tangibles perform significantly better than fingers,despite dealing with a greater number of interactions,in situations that require a large number of acquisitions and basic manipulation tasks such as establishing location and orientation.However,when users have to perform multiple exploration and selection operations that do not require previous basic manipulation tasks,for instance when collections are fixed in the interface layout,touch input is significantly better in terms of required time and number of actions.Finally,when a more elastic collection layout or more complex additional insertion or displacement operations are needed,the hybrid and tangible approaches clearly outperform finger-based interactions. 相似文献

针对目前人们迫切需要舒适人性化的人机交互方式,着重提出一种基于红外感应的多点触控系统,系统中通过红外摄像头得到含有触点的图像,再对图像进行图像分析得到触点的坐标和动作,并最终提交到显示屏幕上,实现与用户的交互。这种方法能满足用户需要大面积触摸范围情景的需求。 相似文献
