Touch & Write: Penabled Collaborative Intelligence

Multi-touch (MT) technology becomes more and more famous and several frameworks have been proposed in the last decade. All of them focus on the support of touch input, gestures, and objects. Recently, however, a new generation of MT-tables emerged, which allows for pen-input in addition to the touch paradigm. These devices, such as the Touch & Write Table of DFKI, consider multiple pen interaction. In this paper we propose a software development kit (SDK) which integrates the basic processing of the pen input. Moreover, the Touch & Write SDK includes handwriting recognition and geometric shape detection. Using writing mode detection the SDK automatically applies the correct recognition component based on features extracted from the pen data.
