As robots have become more pervasive in our daily life, natural human-robot interaction
(HRI) has had a positive impact on the development of robotics. Thus, there has been …

Background With the development of today's technology, and as humans tend to naturally
use hand gestures in their communication process to clarify their intentions, hand gesture …

Air-writing is the process of writing characters or words in free space using finger or hand

Locality-sensitive sparse representation based classification has been shown to be effective
for in-air handwritten Chinese character recognition (IAHCCR). In this paper, we present a …

Air-writing through hand or fingertip is a functional and attractive mechanism. Since there is
usually no pen-up and pen-down in air-writing, trajectory of numbers and words in the air …
