Abstract
A hand gesture may be denoted as a set of motion parameters mathematically which can be applied to a dynamic motion model. To create a library of motion parameter sets, training may be conducted on various hand gestures. Motion parameters corresponding to these observed gestures can be compared to the created reference library of motion parameter sets to respond accordingly to the observed gestures performed by the user.
Background
Since ages, user interfaces needed the presence of user who should physically manipulate the inputs from the input devices like keyboards. However, it is desired to detect and monitor the physical movements of users within an environment. Automated systems can take the user motions and gestures from …show more content…

Detailed Description
Below described are systems and techniques for evaluating motions or gestures of a person’s hand within an environment. A hand gesture can be characterized by a set of motion parameters which can be represented by a dynamic motion model.
A hand gesture may comprise a sequence of pose vectors, where each pose vector indicates the position and orientation of the hand at a time. The position and orientation can be specified by measuring the pose parameters with respect to previous poses in the sequence.
A library can be created for reference gestures by performing training sessions where people should perform gestures with their hands repetitively. Each attempt of performing a gesture is monitored to create a corresponding motion sequence. Numerous monitored motion sequences may be averaged or combined to generate a reference sequence for that gesture. Each reference sequence can be examined to estimate motion parameters that are applied to a dynamic motion model. All these multiple sets of motion parameters corresponding to various hand gestures are stored in the memory to create a reference library.
Various types of sensors and cameras can be used to capture the images denoting the environment and the person’s hand within it.
An Augmented Reality Function Node(ARFN) consists of one or more computing devices, multiple projectors to project any content onto a surface in the environment, multiple cameras to capture the images of the user
