Simultaneous Localization and Recognition of Dynamic Hand Gestures [PDF]

open access: yes, 2004
A framework for the simultaneous localization and recognition of dynamic hand gestures is proposed. At the core of this framework is a dynamic space-time warping (DSTW) algorithm, that aligns a pair of query and model gestures in both space and time. For

Ultra-Low Power Hand Gesture Sensor Using Electrostatic Induction

open access: yesSensors, 2021
This paper presents an ultra-low power hand gesture sensor using electrostatic induction for mobile devices. Two electrodes, which consist of electret foils stacked on metal sheets, are used to recognize two gestures such as hand movements from left to ...

Skeleton-Based Dynamic Hand Gesture Recognition Using an Enhanced Network with One-Shot Learning

open access: yesApplied Sciences, 2020
Dynamic hand gesture recognition based on one-shot learning requires full assimilation of the motion features from a few annotated data. However, how to effectively extract the spatio-temporal features of the hand gestures remains a challenging issue ...

Dynamic Hand Gesture Classification Based on Radar Micro-Doppler Signatures [PDF]

open access: yes, 2016
Dynamic hand gesture recognition is of great importance for human-computer interaction. In this paper, we present a method to discriminate the four kinds of dynamic hand gestures, snapping fingers, flipping fingers, hand rotation and calling, using a ...

Hand Motion and Posture Recognition in a Network of Calibrated Cameras

open access: yesAdvances in Multimedia, 2017
This paper presents a vision-based approach for hand gesture recognition which combines both trajectory and hand posture recognition. The hand area is segmented by fixed-range CbCr from cluttered and moving backgrounds and tracked by Kalman Filter.

HAGR-D: A Novel Approach for Gesture Recognition with Depth Maps

open access: yesSensors, 2015
The hand is an important part of the body used to express information through gestures, and its movements can be used in dynamic gesture recognition systems based on computer vision with practical applications, such as medical, games and sign language ...

Recognizing hand gestures [PDF]

open access: yes, 1994
This paper presents a method for recognizing human-hand gestures using a model-based approach. A Finite State Machine is used to model four qualitatively distinct phases of a generic gesture. Fingertips are tracked in multiple frames to compute motion trajectories, which are then used for finding the start and stop position of the gesture. Gestures are

Hand gesture recognition with jointly calibrated Leap Motion and depth sensor [PDF]

open access: yes, 2015
Novel 3D acquisition devices like depth cameras and the Leap Motion have recently reached the market. Depth cameras allow to obtain a complete 3D description of the framed scene while the Leap Motion sensor is a device explicitly targeted for hand ...

Spatial and Temporal Hand-Raising Recognition from Classroom Videos Using Locality, Relative Position-Aware Non-Local Networks and Hand Tracking

open access: yesVietnam Journal of Computer Science, 2023
Hand-raising gesture is one of the most popular signs of communication, whose frequency is related to the classroom’s atmosphere, the attractiveness of the subject, and the level of interactions between students and teachers.

Look at Me: Early Gaze Engagement Enhances Corticospinal Excitability During Action Observation [PDF]

open access: yes, 2018
Direct gaze is a powerful social cue able to capture the onlooker's attention. Beside gaze, head and limb movements as well can provide relevant sources of information for social interaction. This study investigated the joint role of direct gaze and hand
