IntroductionAs one of the most distinguished features which differ from other animals, the human hand is attracting more and more research interests for building human-like robotic hand with not only similar dexterous manipulation but also the safe operation, which can be of great help in mobile robots, industries and healthcare.

Especially, the ACT hand [6] has not only the same kinematics but also the similar anatomical structure with the human hand, providing a good start for the new generation of anatomical robotic hands. It was also supposed to have an innate merit of safety because of the human-like constrains and its particular structure design. However anatomically correct robotic hands are still in their early stages due to the lack of appropriate sensory systems, unsolved human-robot interaction HRI problems, mysterious neuroscience issues, etc.

Since more and more robots appear in people's home and office, the safety of humans interacting with robots is becoming a matter of concern for robotic researchers [8,9]. The safety in terms of collaborating with robotic hands in HRI can be achievable by designing human-like robotic hand and its corresponding safety strategies.

Humanlike structure design enables robotic hand to have the natural constrains and be suitable to work in the human-studded environment [6]. While safety strategies provide a mechanism to deal with uncertain situations to ensure human safety [10][11][12].

In HRI, human hand gesture is an important way to deliver message or teach by demonstration, and it also indicates the content of the safety. Good performance in hand motion recognition can not only provide robots with correct decisions but also avoid the potential safety hazards [13].

Various methods have been used or created for the human hand motion recognition in recent years, such as neural network [14], support vector machine [15], fuzzy rule-based methods [16,17] and so on. On the other hand, Bernardin et al. Ju et al. Gaussian Model is confined to normal distributed clusters, so that more Gaussian components are needed for approximating the data with curve manifolds [22,23]. The reason that these two statistical methods are popular is that they are very rich in mathematical structure and hence their theoretical basis can be adopted for a wide range of applications.

Empirical Copulas were introduced and first studied by Deheuvels in [24,25], which can be used to study the interrelations of marginal variables with unknown underlying distributions. Dempster et al. Ma and Sun [27] proposed a Chow-Liu like method based on a dependence measure via Empirical Copula to estimate maximum spanning product copula with only bivariate dependence relations while Morettin et al.

Copula has been applied widely to areas of finance [29] such as option pricing and portfolio value-at-risk to deal with the skewness. However, little research has been done to apply Copula to machine learning field. In this paper, we introduce another statistical method, Empirical Copula, into the field of recognizing human hand motions for the first time. The results of experiments on the grasp dataset and in-hand manipulation dataset are compared with those of GMMs, HMMs and TC, to demonstrate its recognition efficiency.

Datasets of these motions are captured by Cyberglove. This paper is organized as follows: Sect. Finally the paper is concluded with conclusions and future work. Dependence Structure Estimation via Empirical CopulaAs a general way of formulating a multivariate distribution, copula can be used to study various general types of dependence between variables. Other ways of formulating multivariate distributions include conceptually-based Carpentry And Joinery Hand Tools Quality approaches in which the Block Plane Hand Tool Not Found real-world meaning of the variables is used to imply what types of relationships might occur.

In contrast, the approach via copulas might be considered as being raw, but it does allow much more general types of dependencies to be included than would usually be invoked by a conceptual approach. The measures of dependence via copula include Kendall's tau, Spearman's rho, Gini's gamma and Blomgvist Beta, whose relationships have been analyzed in [30].

Spearman's rho is considered in this paper. Hand Grasps and Manipulation Skills: Clinical Perspective of Development and Function, Second Edition is an expertly designed and logically organized text that provides an accurate and clear depiction of the development of hand grasps and the taxonomy of functional hand grasp.

Edwards, Donna B. Gallen, Jenna D. McCoy-Powlen, and Michelle A. Suarez is full of concise and user-friendly text that is written to assist in understanding complex information. The photographs, illustrations and charts have been expanded in this Second Edition and present new content areas for students and clinicians to use in education and practice. Hand Grasps and Manipulation Skills, Second Edition is unique in that it is also the only text on the market that contains this comprehensive pictorial information about hands and their grasps.

Additional unique features include rare information about in utero development of the hand, left handedness, scissor skill development, in hand manipulation skills, and extensive information regarding clinical application.
