Computers tend to fail to classify human faces by gender, especially upon changes in viewpoint or upon occlusion that make it more difficult to extract the necessary image features. In contrast, humans are good at identifying gender but have difficulties in dealing with a large number of images. Accounting for this gap, we proposed FaceCAPTCHA, a novel(More)
This paper discusses a new technique that reproduces a stable cloth without introducing excessive damping artifacts. Semi-implicit integration methods have been widely used in cloth simulations for their high stability and speed. Artificial internal damping forces are derived from the linearization process of semi-implicit integration. This makes the system(More)
UTOPIA , introduced in this paper, is a campus-wide advanced ubiquitous computing environment. Research in UTOPIA spans various components each of which is essential to realize UTOPIA: from user device hardware / software, user interface, communication technology, indoor / outdoor testbed, middleware to practical applications. We designed and implemented a(More)
A bs tr act. We attempt to find the suitable modeling for complex gesture patterns so that we can utilize it for their recognition and reproduction. As a result, we propose a hybrid framework where the observable characteristics of gestures are modeled explicitly, while pattern details are processed by blind learning methods. Our hybrid approach thus(More)
As much as stories need to be told, images need to be presented. Although visualizations are meant to be self-explanatory, often enhancing their expressive power by incorporating a certain degree of interactivity, visualized images today often fail to encourage the active engagement of the user/audience. In many cases, interactive interventions by a human(More)
The best spatial design condition to satisfy the occupancy needs of amenity and efficiency is determined through analyzing the spatial design adequacy (SDA). In this study, the relationship between the space design elements and space on future occupants' perception are analyzed. The thirty-three participants reported their self-evaluated SDA that describes(More)
This paper introduces Entry, a visual programming application which is developed to facilitate children's computational thinking. As an HTML5-based visual programming platform, it provides children and beginners with an integrated environment in which they not only learn programming in an easy and fun way but also create, post and share their own programs.(More)
