Searching for an item in a long ordered list that does not fit the screen is a frequent task when using mobile devices. This paper explores four different interfaces to support blind users in carrying out this task. Two of them are based on the idea of tree-augmentation of a list, proposed by Furnas [3], and differ in their depth versus breadth ratio. The other two interfaces adopt the more traditional technique of list scrolling based respectively on standard multitap and T9 keyboard entry. The paper reports also on the results of a pilot study of the four interfaces conducted on two blind users.

In case of the scanning document images, they are mostly the low-resolution images and the skew images. Many document images can be applied to a variety of pattern recognition area. The document images need the image preprocessing including the process of rotation. In this study, we used of three rotation processing methods: one-pass method, two-pass method, and three-pass method, for the skew coordinate transforming of the document images. We compared the result images of three rotation methods and analyzed the time complexities of three rotation methods. In this paper, we took better results in the three-pass rotation method for the document images under the angle condition between one and fifteen. And the three-pass rotation method had higher speed performance than the one-pass rotation method.

In this paper we describe a new iterative translation process designed to leverage the massive number of online users who have minimal or no bilingual skill. The iterative process is supported by combining existing machine translation methods with monolingual human speakers. We have built a Web-based prototype that is capable of yielding high quality translations at much lower cost than traditional professional translators. Preliminary evaluation results of this prototype confirm the validity of the approach.
We introduce a design technique, Clear Panels, to design interactive mobile device applications. Using mixed-fidelity prototyping, a combination of low- and high-tech materials, participants refine multiple aspects of...

We introduce HIPerPaper, a novel digital pen and paper interface that enables natural interaction with a 31.8 by 7.5 foot tiled wall display of 268,720,000 pixels. HIPerPaper provides a flexible, portable, and inexpensive medium for interacting with large high-resolution wall displays. While the size and resolution of such displays allow visualization of data sets of a scale not previously possible, mechanisms for interacting with wall displays remain challenging. HIPerPaper enables multiple concurrent users to select, move, scale, and rotate objects on a high-dimension wall display.
