A Review on Hand Gesture Recognition System

Abstract

From the ancient age, gesture was the first mode of communication, after the evolution of human civilization they developed the verbal communication, but still non-verbal communication is equally significant. Such non-verbal communication is not only used for physically challenged person but also it can be efficiently used for various applications such as 3D gaming, aviation, surveying, etc. This is the best method to interact with computer without any peripheral devices. Many Researchers are still developing robust and efficient new hand gesture recognition techniques. The major steps associated while designing the system are: data acquisition, segmentation and tracking, feature extraction and gesture recognition. There are different methodologies associated with several substeps present at each step. A various segmentation and Tracking, feature extraction and recognition techniques are studied and analyzed. This paper reviews the comparative study of various hand gesture recognition techniques which are presented up-till now.

Dynamic Hand Gesture to Text using Leap Motion

“…In general, hand gestures fall into two categories: 1) static; and 2) dynamic. A static hand gesture refers to a still and stable shape of the hand, while a dynamic hand gesture is movements of the hand to express a specific interaction [3]. Although dynamic hand gestures are more practical for realtime application, they require more computational complexity in processing input signals and in building recognition algorithms [4,5].…”

“…Three technologies can be used to assist in the acquisition of hand gestures: 1) gloved-based; 2) vision-based; and 3) depth-based [3,7]. Gloved-based technology or data glove uses wearable sensors that typically mounted on fingers and wrist to capture the position and movement of the hand.…”

HD: Efficient Hand Detection and Tracking

“…Finally, to compute a blob defined by labeled connected regions, morphological operations [4], [46], such as dilation, filling, etc. are applied to the extracted foreground F , in order to exploit the existing information on the neighboring pixels, in the frame: (F (x, y)).…”

Representation of Intractable Objects and Action Sequences in VR Using Hand Gesture Recognition

“…In recent years, many innovative Human-Computer-Interaction (HIC) controllers have emerged into a process of creation the new gameplay experiences in video games [6,13,15]. Each of the 7 th generation of game consoles -Xbox 360, PlayStation 3 and Wii has introduced their visions of the interaction with games.…”
