Wang, Danli, Shen, Li and Wang, Hongan (2012): A collaborative sketch animation creation system on mobile devices. In: Companion Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 239-242.

In this paper, we introduced a collaborative sketch animation system on mobile devices, enabling 2-users to create animation collaboratively in real time. By simple operations, the two users can not only sketch animation collaboratively but also exchange information and feelings anytime, anywhere. This system is implemented on the NOKIA N800 and N900 smart phone. We conducted a user study to validate the system. Users recognized this system as a novel way for entertainment, creation and communication.

Jiang, Yingying, Tian, Feng, Zhang, Xiaolong, Liu, Wei, Dai, Guozhong and Wang, Hongan (2012): Unistroke gestures on multi-touch interaction: supporting flexible touches with key stroke extraction. In: Proceedings of the 2012 International Conference on Intelligent User Interfaces 2012. pp. 85-88.

Gesture inputs on multi-touch tabletops usually involve multiple fingers (more than two) and casual touchdowns or liftoffs of fingers. This flexibility of touch gestures allows more natural user interaction, but also poses new challenges for accurate recognition of multi-touch gestures. To address these challenges, we propose a new approach to recognize flexible multi-touch stroke gestures on tabletops. Based on a user study on multi-touch unistroke gestures, we develop a gesture recognition method by extracting key strokes embedded in flexible multi-touch input. Our evaluation study result shows that this method can greatly improve the recognition accuracy of flexible multi-touch unistroke gestures on tabletops.

In this paper, we introduce the design and implementation of TempoString, an easy-to-use tool which assists children with music creation. It provides such a fun and novel platform by allowing children to "draw" music on a canvas and then edit it using a rope. The main contribution of our work is the novel access which allows children to "paint" music on a canvas and then edit using a rope.

Wang, Danli, Zhang, Yang, Gu, Tianyuan, He, Liang and Wang, Hongan (2012): E-Block: a tangible programming tool for children. In: Adjunct Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 71-72.

E-Block is a tangible programming tool for children aged 5 to 9 which gives children a preliminary understanding of programming. Children can write programs to play a maze game by placing the programming blocks in E-Block. The two stages in a general programming process: programming and running are all embodied in E-Block. We realized E-Block by wireless and infrared technology and gave it feedbacks on both screen and programming blocks. The result of a preliminary user study proved that E-Block is attractive to children and easy to learn and use.

Lu, Fei, Tian, Feng, Jiang, Yingying, Cao, Xiang, Luo, Wencan, Li, Guang, Zhang, Xiaolong, Dai, Guozhong and Wang, Hongan (2011): ShadowStory: creative and collaborative digital storytelling inspired by cultural heritage. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1919-1928.

With the fast economic growth and urbanization of many developing countries come concerns that their children now have fewer opportunities to express creativity and develop collaboration skills, or to experience their local cultural heritage. We propose to address these concerns by creating technologies inspired by traditional arts, and allowing children to create and collaborate through playing with them. ShadowStory is our first attempt in this direction, a digital storytelling system inspired by traditional Chinese shadow puppetry. We present the design and implementation of ShadowStory and a 7-day field trial in a primary school. Findings illustrated that ShadowStory promoted creativity, collaboration, and intimacy with traditional culture among children, as well as interleaved children's digital and physical playing experience.

Wang, Danli, Zhang, Cheng and Wang, Hongan (2011): T-Maze: a tangible programming tool for children. In: Proceedings of ACM IDC11 Interaction Design and Children 2011. pp. 127-135.

This paper presents a tangible programming tool 'T-Maze' for children aged 5 to 9. Children could use T-Maze to create their own maze maps and complete some maze escaping tasks by the tangible programming blocks and sensors. T-Maze uses a camera to, in real-time, catch the programming sequence of the wooden blocks' arrangement, which will be used to analyze the semantic correctness and enable the children to receive feedbacks immediately. And children could join in the game by controlling the sensors during program's running. A user study shows that T-Maze is an interesting programming approach for children and easy to learn and use.

Zhang, Cheng, Shen, Li, Wang, Danli, Tian, Feng and Wang, Hongan (2011): CoolMag: a tangible interaction tool to customize instruments for children in music education. In: Proceedings of the 2011 International Conference on Uniquitous Computing 2011. pp. 581-582.

In this paper, we describe CoolMag, a tangible interaction tool to enable children to create different instruments collaboratively in music education. With CoolMag, children could learn the basic playing methods of different instruments. It also has the potential to inspire children's creativity, because children could adopt objects in daily life (broom, cup, pen etc.) as the carrier of their novel instruments whose appearance may differ from the traditional one.

Tian, Feng, Lv, Fei, Wang, Jingtao, Wang, Hongan, Luo, Wencan, Kam, Matthew, Setlur, Vidya, Dai, Guozhong and Canny, John (2010): Let's play Chinese characters: mobile learning approaches via culturally inspired group games. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 1603-1612.

In many developing countries such as India and China, low educational levels often hinder economic empowerment. In this paper, we argue that mobile learning games can play an important role in the Chinese literacy acquisition process. We report on the unique challenges in the learning Chinese language, especially its logographic writing system. Based on an analysis of 25 traditional Chinese games currently played by children in China, we present the design and implementation of two culturally inspired mobile group learning games, Multimedia Word and Drumming Strokes. These two mobile games are designed to match Chinese children's understanding of everyday games. An informal evaluation reveals that these two games have the potential to enhance the intuitiveness and engagement of traditional games, and children may improve their knowledge of Chinese characters through group learning activities such as controversy, judgments and self-correction during the game play.

Jiang, Yingying, Tian, Feng, Wang, Hongan, Zhang, Xiaolong, Wang, Xugang and Dai, Guozhong (2010): Intelligent understanding of handwritten geometry theorem proving. In: Proceedings of the 2010 International Conference on Intelligent User Interfaces 2010. pp. 119-128.

Computer-based geometry systems have been widely used for teaching and learning, but largely based on mouse-and-keyboard interaction, these systems usually require users to draw figures by following strict task structures defined by menus, buttons, and mouse and keyboard actions. Pen-based designs offer a more natural way to develop geometry theorem proofs with hand-drawn figures and scripts. This paper describes a pen-based geometry theorem proving system that can effectively recognize hand-drawn figures and hand-written proof scripts, and accurately establish the correspondence between geometric components and proof steps. Our system provides dynamic and intelligent visual assistance to help users understand the process of proving and allows users to manipulate geometric components and proof scripts based on structures rather than strokes. The results from evaluation study show that our system is well perceived and users have high satisfaction with the accuracy of sketch recognition, the effectiveness of visual hints, and the efficiency of structure-based manipulation.

Concept maps are an important tool to knowledge organization, representation, and sharing. Most current concept map tools do not provide full support for hand-drawn concept map creation and manipulation, largely due to the lack of methods to recognize hand-drawn concept maps. This paper proposes a structure recognition method. Our algorithm can extract node blocks and link blocks of a hand-drawn concept map by combining dynamic programming and graph partitioning and then build a concept-map structure by relating extracted nodes and links. We also introduce structure-based intelligent manipulation technique of hand-drawn concept maps. Evaluation shows that our method has high structure recognition accuracy in real time, and the intelligent manipulation technique is efficient and effective.

Tian, Feng, Xu, Lishuang, Wang, Hongan, Zhang, Xiaolong, Liu, Yuanyuan, Setlur, Vidya and Dai, Guozhong (2008): Tilt menu: using the 3D orientation information of pen devices to extend the selection capability of pen-based user interfaces. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 1371-1380.

We present a new technique called 'Tilt Menu' for better extending selection capabilities of pen-based interfaces. The Tilt Menu is implemented by using 3D orientation information of pen devices while performing selection tasks. The Tilt Menu has the potential to aid traditional one-handed techniques as it simultaneously generates the secondary input (e.g., a command or parameter selection) while drawing/interacting with a pen tip without having to use the second hand or another device. We conduct two experiments to explore the performance of the Tilt Menu. In the first experiment, we analyze the effect of parameters of the Tilt Menu, such as the menu size and orientation of the item, on its usability. Results of the first experiment suggest some design guidelines for the Tilt Menu. In the second experiment, the Tilt Menu is compared to two types of techniques while performing connect-the-dot tasks using freeform drawing mechanism. Results of the second experiment show that the Tilt Menu perform better in comparison to the Tool Palette, and is as good as the Toolglass.

Jiang, Yingying, Wang, Xugang, Tian, Feng, Ao, Xiang, Dai, Guozhong and Wang, Hongan (2008): Multimodal Chinese text entry with speech and keypad on mobile devices. In: Proceedings of the 2008 International Conference on Intelligent User Interfaces 2008. pp. 341-344.

Chinese text entry is challenging on mobile devices which rely on keypad input. Entering one character may require many key presses. This paper proposes a multimodal text entry technique for Chinese. In this method, Chinese user can enter Chinese text by simultaneously using the simplified phonemic input method named Jianpin with keypad and speech utterance. The key of the technique is a multimodal fusion algorithm, which synchronizes speech and keypad input and fuses redundant information from two modalities to get the best candidate. A preliminary evaluation shows that users appreciate this technique and it could reduce key presses and enhance the input efficiency.

In order to improve stimulus-response compatibility of touchpad in pen-based user interface, we present the tilt cursor, i.e. a cursor dynamically reshapes itself to providing the 3D orientation cue of pen. We also present two experiments that evaluate the tilt cursor's performance in circular menu selection and specific marking menu selection tasks. Results show that in a specific marking menu selection task, the tilt cursor significantly outperforms the shape-fixed arrow cursor and the live cursor [4]. In addition, results show that by using the tilt cursor, the response latencies for adjusting drawing directions are smaller than that by using the other two kinds of cursors.

Ao, Xiang, Wang, Xugang, Tian, Feng, Dai, Guozhong and Wang, Hongan (2007): Crossmodal error correction of continuous handwriting recognition by speech. In: Proceedings of the 2007 International Conference on Intelligent User Interfaces 2007. pp. 243-250.

In recognition-based user interface, users' satisfaction is determined not only by recognition accuracy but also by effort to correct recognition errors. In this paper, we introduce a crossmodal error correction technique, which allows users to correct errors of Chinese handwriting recognition by speech. The focus of the paper is a multimodal fusion algorithm supporting the crossmodal error correction. By fusing handwriting and speech recognition, the algorithm can correct errors in both character extraction and recognition of handwriting. The experimental result indicates that the algorithm is effective and efficient. Moreover, the evaluation also shows the correction technique can help users to correct errors in handwriting recognition more efficiently than the other two error correction techniques.

In this paper a novel approach is described for tree visualization using nested circles. The brother nodes at the same level are represented by externally tangent circles; the tree nodes at different levels are displayed by using 2D nested circles or 3D nested cylinders. A new layout algorithm for tree structure is described. It provides a good overview for large data sets. It is easy to see all the branches and leaves of the tree. The new method has been applied to the visualization of file systems.
