Gesture-Based Intelligent User Interface for Control of an Assistive Mobile Information Robot.

This article presents a gesture-based user interface for a robotic shopping trolley. The trolley is designed as a mobile robotic platform helping customers in shops and supermarkets. Among the main functions are: navigating through the store, providing information on availability and location, and transporting the items bought. One of important features of the developed interface is the gestural modality, or, more precisely, Russian sign language elements recognition system. The notion of the interface design, as well as interaction strategy, are presented in flowcharts, it was made an attempt to demonstrate the gestural modality as a natural part of an assistive information robot. Besides, a short overview of mobile robots is given in the paper, and CNN-based technique of gesture recognition is provided. The Russian sign language recognition option is of high importance due to a relatively large number of native speakers (signers).
