Abstract

This paper presents novel text input methods for mobile devices. In particular, it shows how users can capture text from books, newspapers, and other objects by using the digital cameras that are integrated into an increasing number of smartphones. The idea is to select text from a live video stream generated by these digital cameras. Different interaction patterns are discussed that allow users to select text: (1) automatic detection of the word closest to a fixed position on the mobile device's screen, (2) delayed movement of the text selection to improve the precision of the selection procedure, and (3) using the stylus to select words and word groups. The proposed interaction patterns are evaluated based on the results of a user study, and their application is shown in an example scenario. The presented research has practical relevance because it can improve the usability of mobile applications such as online searching
在移动设备上使用数码相机进行文本输入
本文提出了一种新的移动设备文本输入法。特别是,它展示了用户如何使用集成到越来越多的智能手机中的数码相机,从书籍、报纸和其他物体上捕捉文字。这个想法是从这些数码相机产生的实时视频流中选择文本。讨论了允许用户选择文本的不同交互模式:(1)自动检测移动设备屏幕上最靠近固定位置的单词;(2)延迟文本选择的移动以提高选择过程的精度;(3)使用触控笔选择单词和单词组。根据用户研究的结果对建议的交互模式进行评估,并在示例场景中展示它们的应用程序。所提出的研究具有实际意义,因为它可以提高移动应用程序的可用性,如在线搜索
