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

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
Gestures: A lively and animated teaching style captures students’ attention, makes the material more interesting, and facilitates learning. Head nods also communicate positive reinforcement to students and indicate that you are listening.
Gestures: Gestures such as waving, pointing, and using fingers to indicate signals are commonly used in our daily life. These are deliberate movement used to convey signals without uttering a word. Gestures varies as per professions, cultures, nations, person etc.For an instance if waving my hand towards my friends
Gestures are ways of communicating with others using our body. For example, we use our hands to wave, which is another way of saying hello.
(You may ask people from other countries/and or conduct your own web search or library search for answers). Some suggested countries/cultures to research might be: Italy, Japan, China, Greece, and the Middle East (10 points)
6. Identify the movements associated with the arm, forearm, wrist, and fingers. Rotation, flexing, extension, hyperextension, proation, and supination.
| Gestures – using gestures can help to explain the conversation to make sure that the person can understand what you are trying to say and sometimes it helps support your conversation if someone finds it hard to understand.
The second design exercise involved me exploring more into the possibilities of using the laser cutting technology for 3D scanning with different drawing software. In this exercise, I made a small replica of my hand doing a classical Indian dance gesture, ‘Hamsasya’. This was done by scanning my hand using a ‘structure sensor’ device in which was attached to an ipad and examined around my hand.
The hand is a very important extremity attached to the human body and is used in everyday life. Humans use it doing almost everything. The major systems the body uses to be able to move the hands are the skeletal, muscular and nerves systems. The skeletal system of the hand involves the bones, such as, eight carpal bones, five metacarpal and fourteen finger bones (Istitute for Quality & Efficiency in Health Care, 2013). All connected by joints and ligaments. The muscles include two parts, the thenar eminence and the hypothenar eminence (Istitute for Quality & Efficiency in Health Care, 2013). The thenar eminence moves the base of the thumb, also lets the thumb touch the four fingers; the hypothenar eminence allows the little finger to bend

Using body gestures to show certain actions like finger pointing to show something specific ex: directions, signs or pictures.
Dr. Ivan, use all five of these body language, his posture was standing in a relaxed professional manner, body movement was walking to the other side of the room, hand and arm gestures move conversationally, facial expression look natural and relaxed in animated, and had good eye contract with the audience. When Dr. Ivan open his speech, he using hand expansive gestures. While he was speaking, his hand was moving conversationally, with hands open and palms out. Although, this shows me, he was emphasizing a point in the presentation. Therefore, I feel the hands gesture was expressing, that he is certain about what he talking about. Aa a result, he held my attention as audience, this give me expression that he open and honest about the subject.
From 2015 to present have been gaining research experience in the Psychology Department, University of Connecticut. We were able to integrate and analyze data from eye movement and finger movement.
Gestures benefit the receiver and the sender, often taking the place of words. This type of nonverbal communication can be used to convey an understanding, aid in revealing complex ideas and to get attention. Gestures can be done to show listening and comprehension, such as a head nod. These can also help to explain, answer or promote what is being said verbally in a visual way. An example of this would be in a conversation with someone. The person speaking may gestures money by rubbing their fingers to their thumb, to highlight the subject of money which is being spoken upon. Another example would be in the discussion of distance or large size extending hands and arms out from the body, thus emphasizing the extreme amount being discussed.
It is important to recognize that body language may vary between individuals, and between different cultures and nationalities. It is therefore essential to verify and confirm the signals that you are reading, by questioning the individual and getting to know the person. Recognising and responding to body
