Accelerometer based gesture recognition robot

Abstract

Gesture recognition can be termed as an approach in this direction. It is the process by which the gestures made by the user are recognized by the receiver. Gestures are expressive, meaningful body motions involving physical movements of the fingers, hands, arms, head, face, or body

with the intent of:

• conveying meaningful information or
• interacting with the environment.

They constitute one interesting small subspace of possible human motion. A gesture may also be perceived by the environment as a compression technique for the information to be transmitted elsewhere and subsequently reconstructed by the receiver.

Classification

hand and arm gestures:

Recognition of hand poses, sign languages, and entertainment applications.

head and face gestures:

Nodding or shaking of head; direction of eye gaze; etc.;

body gestures:

involvement of full body motion, as in; tracking movements of two people interacting outdoors; analyzing movements of a dancer for generating matching music and graphics;

Benefits:

A human computer interface can be provided using gestures:

Replace mouse and keyboard

Pointing gestures

Navigate in a virtual environment

Pick up and manipulate virtual objects

Interact with the 3D world
