In this paper, we develop an interactive haptic system, which can be further aid for digital Chinese painting. When an artist is holding our force feedback device, one feels like holding a real painting brush with all the contact and bending forces, since the viscosity, friction, and the bending force of a brush touching the paper are simulated. First we derive a physical dynamics model as bend...

WINTER 2015 51 Computer-based educational technology has had a transformative impact in every imaginable educational context — from tablet-based educational games for preschoolers, to massively open online courses for university students and independent learners. Artificial intelligence (AI) research solutions have the potential to boost the impact of these systems by enhancing their diagnostic...

We describe a method for on-line handwritten signature veri!cation. The signatures are acquired using a digitizing tablet which captures both dynamic and spatial information of the writing. After preprocessing the signature, several features are extracted. The authenticity of a writer is determined by comparing an input signature to a stored reference set (template) consisting of three signatur...

New kinds of documents such as handwritten online documents are emerging, which are produced by digital devices such as Tablet PC, personal handheld devices or digital paper coupled with digital pens. The rapid increase in the number of such handwritten online documents leads to mounting pressure on finding innovative solutions towards faster processing, indexing and retrieval of the documents ...
