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(More)
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(More)
Concept maps are an important tool to organize, represent, and share knowledge. Building a concept map involves creating text-based concepts and specifying their relationships with line-based links. Current concept map tools usually impose specific task structures for text and link construction, and may increase cognitive burden to generate and interact(More)
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(More)
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(More)
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(More)
In this paper, we performed an exploration on the design and evaluation of pen tail gesture, an interaction method that allows the use of pen tail movement to initiate interactions. Based on our interviews with some designers and researchers who regularly used pen-based tools, we conducted three experiments to establish baseline criteria to distinguish(More)
In this paper, we propose a novel method called Rotational Region CNN (R 2 CNN) for detecting arbitrary-oriented texts in natural scene images. The framework is based on Faster R-CNN [1] architecture. First, we use the Region Proposal Network (RPN) to generate axis-aligned bounding boxes that enclose the texts with different orientations. Second, for each(More)
