Mobile ShopAssist
Rainer Wasinger, DFKI GmbH

Description:

The Mobile ShopAssist is a Pocket PC application used to demonstrate the use of natural language technologies within a stereo-typical shopping environment.  Mobile and multimodal input interaction is the central theme of this application. Through the use of a blackboard architecture and modality fusion techniques, users can interact flexibly with both physical real-world objects on a shelf, and their digital-world counterparts shown on a Pocket PC display. Interaction can take place in the form of intra- and extra- gestures, speech, handwriting, and mixed-modal combinations based on the aforementioned modalities. Objects are also capable of initiating a dialog with the user when picked up from the shelf. The application caters for English and German speakers, and it was demonstrated with a product base of digital cameras at CeBIT 2005 and CeBIT 2006.

This work was carried out at the DFKI GmbH and the University of Saarland, under the project COLLATE/COLLATE II (Computational Linguistics and Language Technology for Real Life Applications), which was funded by the German BMBF (01.01.2001 - 31.12.2006). In particular, the work falls under the theme M3I (Mobile and MultiModal Interaction), and it has the goal of bringing people closer to cutting edge language technology.
