Cochlear Implant Microphone Location Affects Speech Recognition in Diffuse Noise
Authors: Kolberg Elizabeth R. , Sheffield Sterling W. , Davis Timothy J. , Sunderhaus Linsey W. , Gifford René H.
Published: January 2015

Background:Despite improvements in cochlear implants (CIs), CI recipients continue to experience significant communicative difficulty in background noise. Many potential solutions have been proposed to help increase signal-to-noise ratio in noisy environments, including signal
processing and external accessories. To date, however, the effect of microphone location on speech recognition in noise has focused primarily on hearing aid users.Purpose:The purpose of this study was to (1) measure physical output for the T-Mic as compared with the integrated behind-the-ear
(BTE) processor mic for various source azimuths, and (2) to investigate the effect of CI processor mic location for speech recognition in semi-diffuse noise with speech originating from various source azimuths as encountered in everyday communicative environments.Research Design:A repeated-measures,
within-participant design was used to compare performance across listening conditions.Study Sample:A total of 11 adults with Advanced Bionics CIs were recruited for this study.Data Collection and Analysis:Physical acoustic output was measured on a Knowles Experimental Mannequin
for Acoustic Research (KEMAR) for the T-Mic and BTE mic, with broadband noise presented at 0 and 90° (directed toward the implant processor). In addition to physical acoustic measurements, we also assessed recognition of sentences constructed by researchers at Texas Instruments, the Massachusetts
Institute of Technology, and the Stanford Research Institute (TIMIT sentences) at 60 dBA for speech source azimuths of 0, 90, and 270°. Sentences were presented in a semi-diffuse restaurant noise originating from the R-SPACE 8-loudspeaker array. Signal-to-noise ratio was determined individually
to achieve approximately 50% correct in the unilateral implanted listening condition with speech at 0°. Performance was compared across the T-Mic, 50/50, and the integrated BTE processor mic.Results:The integrated BTE mic provided approximately 5 dB attenuation from 1500‐4500
Hz for signals presented at 0° as compared with 90° (directed toward the processor). The T-Mic output was essentially equivalent for sources originating from 0 and 90°. Mic location also significantly affected sentence recognition as a function of source azimuth, with the T-Mic
yielding the highest performance for speech originating from 0°.Conclusions:These results have clinical implications for (1) future implant processor design with respect to mic location, (2) mic settings for implant recipients, and (3) execution of advanced speech testing in the
clinic.

Remembering a sociology of Human Rights
Authors: Levy Daniel , Sznaider Natan
Published: January 2015

A sociology of human rights sounds almost like a contradiction in terms. Sociology is about social groups, about particular experiences, about how people, embedded in space and time, make sense of their lives and give meaning to their world. It deals with power and interest and the social bases of our experiences. On the other hand, human rights are about human beings in general, without temporal or spatial references, not about groups and their boundaries. Human rights are about humanity, located in the world and connected to an inviolable nature. Global media representations, among others, create new cosmopolitan memories, providing new epistemological vantage points and emerging moral-political interdependencies. As such, memories of the Holocaust contribute to the creation of a common European cultural memory based on the abstract notion of human rights. Sociologically, a theory of human rights has to show how universal and particular memories co-exist, are reconciled etc. and what it means for the recognition of the “other”, and the broadening of circles of solidarity.
The Impact of Consumer Choice Goals on Inovativeness
Authors: Korelo Jose Carlos , Lucena da Silva Danielle Mantovani , Prado Paulo Henrique Muller
Published: January 2015

Consumer innovativeness is one of the most explored concepts in new product adoption literature. Nevertheless, the intention to adopt novelties, specifically in a product category domain, still needs exploration of what happened during the choice process. Consumers can build their decision about whether to adopt innovation based on their hierarchy of choice goals. The authors propose this hierarchy is driven by the regulatory focus system, based on promotion (justifiability and choice confidence) and prevention goals (anticipated regret and evaluation costs). In order to demonstrate this reasoning, the authors compared “most innovative” versus “less innovative” consumers, regarding their prevention and promotion goals. The most innovative ones demonstrated higher justifiability and choice confidence and showed more capabability of avoiding an anticipated choice regret when compared with the less innovative consumers. The differences explored in the analysis highlight the necessity of further understanding how consumers perform during the choice process of innovative products.
Electronic Government
Authors: Moreira António Carrizo , Zimmermann Ricardo Augusto
Published: January 2015

E-government has become a priority for many governments around the world and one of the main change drivers in the provision of new services in the public administration context. As public services are part of a complex network in which citizens are the main players, public authorities are increasingly trying to identify and deploy programmes that promote the modernisation and simplification of public services based on knowledge management. This chapter aims to understand the impact of e-government initiatives on consumer behaviour, as well as the importance of knowledge management for value creation in the public administration context. The Simplex programme, the main initiative in Portugal to develop administrative simplification and e-government, is analysed within two contexts: the central administration and the local municipality of Oporto. This chapter highlights that e-government has been an important factor contributing to both the administrative simplification and the improvement in the quality of public services.
Customer Knowledge Management (CKM)
Authors: Heavin Ciara , Adam Frederic
Published: January 2015

SMEs operating in high-tech sectors are typically reliant on specialist knowledge to help them build the right product with the objective of meeting customer needs. The nature of niche software markets means that products must be closely informed by customer requirements for the software product to be a success. The importance of understanding how smaller organisations manage knowledge has become vital to their success; however, there remains a dearth of empirical research in SMEs in the area of IS research. Using a qualitative analysis approach in five Irish software SMEs, this chapter identifies how this type of organisation leverages their customers as external knowledge resources, with particular emphasis on knowledge acquisition, a Knowledge Activity (KA) in which customers play a significant part. Through the establishment of KAs a firm can develop an approach to Customer Knowledge Management (CKM) to build value-creating relationships with a reliable customer base.
Knowledge Management as a Tool for Influencing Customers
Authors: Brunet-Thornton Richard , Marešová Petra , Bureš Vladimír , Otčenášková Tereza
Published: January 2015

This chapter revisits an earlier published model of the Cost-Benefit Analysis method focused on KM projects. Although it continues to centre on the customer and the general market environment as knowledge sources used to evaluate the appropriateness of a Knowledge Management (KM) project, it expands the discussion to incorporate the latest research on this topic. In addition, the tangible and intangible benefits of a successful KM deployment continue to be stressed; it highlights the various barriers and sets recommendations that may be pursued. Given the on-going nature of this condition in the Czech Republic, the authors continue to pursue an active research protocol.
Creating Open Source Lecture Materials
Authors: Hsu William H.
Published: January 2015

This chapter surveys recent and continuing trends in software tools for preparation of open courseware, in particular audiovisual lecture materials, documentaries and tutorials, and derivative materials. It begins by presenting a catalog of tools ranging from open source wikis and custom content management systems to desktop video production. Next, it reviews techniques for preparation of lecture materials consisting of five specific learning technologies: animation of concepts and problem solutions; explanation of code; video walkthroughs of system documentation; software demonstrations; and creation of materials for instructor preparation and technology transfer. Accompanying the description of each technology and the review of its state of practice is a discussion of the goals and assessment criteria for deployed courseware that uses those tools and techniques. Holistic uses of these technologies are then analyzed via case studies in three domains: artificial intelligence, computer graphics, and enterprise information systems. An exploration of technology transfer to college and university-level instructors in the information sciences then follows. Finally, effective practices for encouraging adoption and dissemination of lecture materials are then surveyed, starting with comprehensive, well-established open courseware projects that adapt pre-existing content and continuing through recent large-scale online courses aimed at audiences of tens to hundreds of thousands.

Authors: Wengang Li , Yulai Chen , Jia Guo
Published: January 2015

Since the Reform and Opening up in the late 1970s, China has been seeking an innovation-driven knowledge society. In the past decade, the central government and local governments took effective measures to quicken China's steps towards a knowledge society. In the recent 18th National Congress of the CPC, reform and innovation was highly emphasized to give fresh impetus to knowledge society building. Within the context of increasing globalization and Africa-China long-lasting friendship and cooperation, China and African countries can learn from each other in knowledge society construction. As the second largest economy in the world, China is playing an increasing role in knowledge society construction in Africa. Can Africa learn from China's experiences? This chapter provides some answers to this query.
Supporting Mathematical Communication through Technology
Authors: Orrill Chandra Hawley , Polly Drew
Published: January 2015

Technology has the potential to support the creation and use of mathematical representations for exploring, reasoning about, and modeling cognitively demanding mathematical tasks. In this chapter, the authors argue that one of the key affordances of these dynamic representations is the synergistic relationship they can play with communication in the mathematics classroom. The authors highlight the ways in which technology-based representations can support mathematical communication in the classroom through a series of vignettes. They conclude with a discussion of the development of teachers' Technological Pedagogical and Content Knowledge (TPACK) for supporting the implementation of dynamic representations.
Strategy Instruction and Maintenance of Basic Multiplication Facts through Digital Game Play
Authors: Denham André R.
Published: January 2015

Formative instruction on multiplication primarily focuses on rote memorization. This leads to factual fluency, but also develops a narrow view of multiplication and hinders the development of conceptual understanding. Theory and research recommend the concurrent development of conceptual understanding and factual fluency during the initial stages of learning about multiplication. Woodward (2006) conducted a field study to investigate this instructional approach and found a significant difference between those who received instruction on multiplicative properties and timed-drills of multiplication facts on a conceptual measure than those who only spent time on timed drills. This study investigated the efficacy of integrating the same approach within a digital game. There was a significant decrease between pre- and post- measures of participants timed retrieval of multiplication facts, but no differences were found between conditions on pre- and post-measures of conceptual understanding. These findings indicate that special attention must be paid to intrinsic integration of instructional content in order to address conceptual understanding through digital game play.
Technology in Mathematics Education
Authors: Eley Peter M.
Published: January 2015

Combining both leadership and diversity, the author's define “leadership diversity” to be: leadership that engages followers that is inclusive to gender, culture, and the social context of the followers. In this chapter, a theoretical framework called “Technological Mathematical Leadership Diversity” (TMLD). TMLD refers to using technology to engage all followers' mathematic learning that is inclusive of their gender, culture, and social context. As mathematics educators, it is important to understand that our role as chief instructor is changing; students are now taking control of their education. The infusion of Web 2.0 is changing how students learn and receive their information. The author set out to answer three questions through the TMLD lens: 1) Will the technology be applied to something already done? 2) Will the technology be used in such a way that it improves upon the way an existing task is done? 3) Will the technology allow us to do things that could not easily be done before? Within this context, the authors organize the technology into two distinct categories “productivity” and “cognitive” based off their primary usage. The rising cost of higher education is driving students to find ways to obtain their education in the quickest time and least expensive way possible. While in pursuit of this, it is important that diversity leadership is maintained. Using frameworks such as TMLD, the authors are able to examine the existence and potential effectiveness of a technological tool. These changes can affect mathematics education in a drastic way.

Authors: Rahman Roselainy Abdul , Baharun Sabariah , Yusof Yudariah Mohamad , Rahman Sharifah Alwiah S. Abdur
Published: January 2015

The paper discusses the results of an action research to improve teaching practice which applied the philosophy of Knowledge – Experiential – Self-regulated (KES) at the Malaysia-Japan International Institute of Technology, Universiti Teknologi Malaysia. The teaching and learning strategies were implemented to achieve the following objectives; (i) to enhance students' mathematical competencies; (ii) to support self-regulated learning; and (iii) to improve the teaching practice of Engineering Mathematics 3 i.e. Advanced Calculus. A modification to a previously developed framework by Roselainy et al. (2012a) was performed to encourage students to adopt self-regulated learning behaviour in an active learning environment. The teaching, learning and assessment activities were aligned constructively based on the theory of Biggs & Tang (2010). Data was collected, analysed and later employed to modify the teaching and learning activities. The findings found that it is imperative for teachers to design an appropriate learning environment and apply suitable strategies in encouraging and supporting students to embrace and take charge of their own learning.
Multiple Perspectives for the Study of Teaching
Authors: Salloum Sara
Published: January 2015

This chapter outlines a framework that characterizes science teachers' practical-moral knowledge utilizing the Aristotelian concept of phronesis/practical wisdom. The meaning of phronesis is further explicated and its relevance to science education are outlined utilizing a virtue-based view of knowledge and practical hermeneutics. First, and to give a background, assumptions about teacher knowledge from a constructivist and sociocultural perspective are outlined. Second, the Aristotelian notion of phronesis (practical wisdom) is explicated, especially in terms of how it differs from other characterizations of practical knowledge in science education and how it relates to practical-moral knowledge. Finally, the authors discuss how the very nature of such practical-moral knowledge makes it ambiguous and hard to articulate, and therefore, a hermeneutic model that explores teachers' practical-moral knowledge indirectly by investigating teachers' commitments, interpretations, actions, and dialectic interactions is outlined. Implications for research and teacher education are outlined. Empirical examples are used to demonstrate certain points. A virtue-based view of knowledge is not meant to replace others, but as a means to enrich the understandings of the complexity of teacher knowledge and to enhance the effectiveness of teacher educators.
Active Learning, Mentoring, and Mobile Technology
Authors: Newman Dianna L. , Lamendola Jessica M. , Deyoe Meghan Morris , Connor Kenneth A.
Published: January 2015

Educators are creating authentic settings that utilize active learning, mobile technology, and mentoring in efforts to promote students' success in developing 21st Century skills, motivation, and interest in STEM domains and STEM careers. Each of these approaches has been found to promote and transfer knowledge, as well as to develop problem-solving and communication skills in STEM. Little information, however, is available about the interactive effect of mobile technology and active learning in promoting learning in settings that use a hierarchical model of mentoring to promote the transfer of skills and knowledge. This chapter presents findings of a program that used mobile technology in active learning environments for five interrelated levels of an active, authentic environment, facilitated by mobile technology and hierarchical mentoring. Positive outcomes were documented at each level of participation; use of the mobile technology integrated within active learning settings supported by hierarchical mentoring increased learning in STEM content, skills, and affect.
Linking Education to Creating a Knowledge Society
Authors: Weber Alan S.
Published: January 2015

Due to the continued high price of oil and gas, the oil-rich State of Qatar has used its large budget surpluses in the last decade to finance human capacity development, including research, higher education, and the reshaping of its K-12 educational system. This chapter argues that the recent substantial educational reforms in the State of Qatar are closely intertwined with planned future economic transformation (diversification). Although Qatar possesses the world's third largest reserves of natural gas, this resource is ultimately finite and over-reliance on one major economic driver (hydrocarbons) for the bulk of GDP creates boom and bust cycles that have shaped Gulf politics and social development since the 1970s. This chapter examines Qatar's educational efforts to build a knowledge economy to transition away from a resource-rich export-based hydrocarbon economy towards economic activities linked to patents, research, trademarked technologies, skills, and knowledge products.
Analysis of Discourse Practices in Elementary Science Classrooms using Argument-Based Inquiry during Whole-Class Dialogue
Authors: Benus Matthew J. , Yarker Morgan B. , Hand Brian M. , Norton-Meier Lori A.
Published: January 2015

This chapter discusses an analysis of discourse practices found in eight different elementary science classrooms that have implemented the Science Writing Heuristic (SWH) approach to argument-based inquiry. The analysis for this study involved examining a segment of whole-class talk that began after a small group presented its claim and evidence and ended when the discussion moved on to a new topic, or when a different group presented. The framework for the analysis of this whole-class dialogue developed through an iterative process that was first informed by previous analysis, review and modification of other instruments, and notable anomalies of difference from this data set. Each classroom was then rated using the Reform Teaching Observation Protocol (RTOP), which provided a score for the extent to which the teacher was engaged with reform-based science teaching practices. Our analysis shows that elements of whole-class dialogue in argument-based inquiry classrooms were different across varying levels of RTOP implementation. Overall, low level RTOP implementation (little evidence of reformed-based practice) had a question and answer format during whole class talk that rarely included discourse around scientific reasoning and justification. Higher levels of RTOP implementation were more likely to be focused on student use of scientific evidence to anchor and develop a scientific understanding of “big ideas” in science. These findings are discussed in relation to teacher professional development in argument-based inquiry, science literacy, and the teacher's and students' grasp of science practice.
Remote Access to Scientific Laboratory Equipment and Competency-Based Approach to Science and Technology Education
Authors: Mazuritskiy M.I. , Safontsev S.A. , Konoplev B.G. , Boldyreva A.M.
Published: January 2015

This article describes the competency-based approach to e-learning education that utilizes remote access to the laboratory equipment. The main focus of the paper is the structure and design of the e-learning system used in the Southern Federal University (Russia). The article discusses the related pedagogical strategies and presents system's features in the context of the education for skilled workers. This approach uses access to the scientific and technology laboratory equipment either for provisioning of the individualized educational programs or to enable the students who are unable to attend a conventional laboratory for a variety of reasons, such as disability, and part-time study to conduct the experimental work. It will be shown that the experimental work involving the modern scientific equipment is an important aspect of the learning process in the areas of material science and nanotechnology. The learning strategy is the reverse of that used in the traditional approach. The authors suggest to start with the introduction to the practical applications of science and technology relevant to the current job market, and study the general laws and theoretical principles afterwards, to deepen understanding and achieve the educational goals.
Blend the Lab Course, Flip the Responsibility
Authors: Gallo Mark A.
Published: January 2015

An upper-level special topics course in Applied, Environmental, and Medical Microbiology was offered for the first time. It was decided by the author to offer it as a blended course. There were some compelling reasons to do so: first and foremost, it allowed class time to be spent doing what one should in a lab-intensive course: remark on current state of knowledge and literature, describe experimental design, discuss potential outcomes, troubleshoot technical problems as they arise, and offer suggestions regarding students' research throughout the process. The ultimate goal and real value of the blended classroom in this instance was elevating the level of student responsibility and forcing them to view a science class as something more than a collection of facts: rather as a very active class, one that requires individual action. It was also designed to allow the students to participate in fundamental scientific research with the help of a mentor in a manner that was/is still practiced and in full view of peer review. The role of the faculty member changes to one of providing guidance instead of content in the classroom, and so it gives one more individual time with the students; this time can be used for diagnostic, formative, and summative assessment.
Design of Continuous Passive Motion Machine Based on Kinematic Model of Lower Limb
Authors: Dwornicka Renata , Dominik Ireneusz
Published: January 2015

The article presents the design of Continuous Passive Motion machine based on kinematic model of lower limb. The machines are used to prevent the stiffening of joints and allow recovering their full functionality after surgical interventions. The research conducted in rehabilitation centers states, that there is a necessity of using the CPM machines. The types of the machines that are currently used do not provide all the natural movements of a healthy organism, though. Such limitations concern not only motions in particular level, but also ranges of motions. There is a need to modernize already existing models, by introducing brand new functions or improving and re-constructing the functions already implemented. Such information resulted in designing a new solution of a CPM machine for the lower limb exercises.

Coverage-Optimized Deployment Research for Maximizing the Sensor Network Coverage
Authors: Zeng Xia Ling
Published: January 2015

For multilayer mobile sensor network, the issues of improving sensor network coverage by the use of mobile sensors are studied. A coverage-optimized deployment algorithm based on grid-division and bipartite graph matching is proposed. Firstly, the deployment area is divided into many grids and build distribution matrix of sensor nodes. Then construct a bipartite graph G based on the grid-division and solve a matching of maximum cardinality of G. It corresponds to an optimal deployment scheme which maximizes the network coverage and minimizes the total movement cost. Results show that after optimized deployment the network coverage increases, and with the increase in the percentage of mobile nodes it increases accordingly. In the way of distributed calculating the network also can achieve a higher coverage ratio and the movement cost is lower. It is very suitable for deployment of multilayer sensor network.

Rapid Transfer Alignment Using Integrated Navigation System as Reference
Authors: Sheng Wei , Han Xiao , Sun Ding Sheng
Published: January 2015

Traditional transfer alignment must use a pure Inertial Navigation System (INS) as the reference, because using the integrated navigation system as the reference would disrupt the transfer alignment process and lead to the divergence of the fine alignment filter. But there are some cases require the cooperation between the master INS and slave INS for long time duration, such as mapping. To guarantee the accuracy of the master INS, integrated navigation feedback is needed. So, transfer alignment technique using the integrated navigation system as the reference is required. Taking the error of master INS into account, a transfer alignment attitude error in the body frame was defined, which makes the transfer alignment attitude error free from the impact of integrated navigation feedback corrections. Then, its error equations were developed and a Kalman filter was designed based on it. Finally, a transfer alignment simulation using a GPS/INS integrated navigation system as reference was performed to validate the proposed scheme.

Published: January 2015

Problems such as low voltage and big line loss have long existing in the power grid in rural areas of China. In recent years, some province and cities have improved voltage and reduced line loss by installing SVG at substations in rural power grids, and the effect is remarkable.With great compensation capacity and a good variety of modes of compensation, SVG is sure to replace old reactive compensation devices in rural power grid in future, which requires evaluation and analysis of SVG reliability so as to guarantee safety and stability of the power grid. However, now no research or analysis has been made in China on SVG reliability in rural power grids, which affects wide promotion of SVG in rural power grids.Under the background of Liaoning Power Grid 10kV/±5Mvar Chain SVG, this paper analyzes the reliability of k/n (G) system model of SVG master circuit structure, improving the accuracy of system reliability estimation. The estimation matches the operation outcome, thus providing data basis for the feasibility of SVG’s wide application in rural power grid in future.

Authors: Xiang Zheng , Tang Yu , Kang Feng
Published: January 2015

Due to the impact of capacity change on traffic flow in single-aerodrome terminal airspace, a strategy to balance traffic flow and capacity in single-aerodrome terminal airspace is studied by introducing the idea of collaborative decision making and law of economics. First, considering factors such as airline’s gross income, operation cost and delay cost, an optimization model based on traffic flow to maximize total airline’s net income is established, and constraints including capacity of single-aerodrome terminal airspace are imposed as well. Then, a genetic algorithm to optimize the above model is proposed and realized. Traffic flow and capacity in single-aerodrome terminal airspace can be balanced by using the proposed strategy, while the total airline’s net income is increased at the same time.

Published: January 2015

Differential Evolution Algorithm (DE) is fast and stable, but it’s easy to fall into the local optimal solution and the population diversity reduces fast in the later period. In order to improve the algorithm optimization and convergence capability, this paper proposes an improved DE algorithm based on the new crossover strategy (CMDE). As to the Crossover-factor is decided by the proportion of the variance and the evolution process in each generation, so it can follow the process of evolution and constantly change; the added operation of Second Mutation can improve the capacity of solving problem, which algorithm falls into the local solution easily. With four standard test functions, the results show that the CMDE algorithm is superior to DE in convergence speed, precise and stability of algorithm.

Equivalence Class Based Parallel Algorithm for Mining MFI
Authors: Wang Hui
Published: January 2015

We present a novel and powerful parallel algorithm, PMFI, for mining all the maximal frequent itemsets from a big database. PMFI utilizes novel technologies to make the I/O overhead down drastically. The key principle is to utilize prefix-based equivalence classes to decompose the search space. It distributes the work among the processors by equivalence class weights. It re-represents the database with vertical format, so the frequency counting can be done by simple tid-list intersection operations. It bases a novel serial algorithm MaxMining which utilizes multiple-level backtrack pruning strategy, so that each processor can count the maximal frequent itemsets independently by selectively duplicating the pieces of database. These techniques eliminate the need for synchronization. The dynamic load balance schema is applied in PMFI, it would be hopeful to achieve better performance.

Published: January 2015

Dynamic optimization scheduling of the gas in iron and steel enterprises has great significance to reduce gas emission and the short-term forecast is the premise to realize the energy dynamic scheduling. Based on the characteristics that the influencing factors of blast furnace gas amount are complex and difficult to collect, a grey radial basis function (RBF) neural network forecast model is proposed to predict the gas amount for blast furnace in this paper. Combining grey theory, which is used to preprocess the historical data and obtain abundant information, with RBF neural network makes the effective trend forecast in the next 30 minutes come true. The model proposed in this paper is proved to be more accurate according to control experiments against the grey BP neural network.

Published: January 2015

The randomness of wind power and the nonstationarity of gearbox vibration signals greatly increased the difficulty of wind turbine gearbox faults feature diagnosis. Studies proved that Hilbert-Huang transform (HHT) has a satisfying performance when it be used to analyze nonlinear and non-stationary signals, but two troublesome problems in application of HHT are end effect problem and false intrinsic mode functions (IMFs). An improved solution method based on adaptive waveform matching endpoint extension is proposed to solve end effect problem. Meanwhile, an improved energy conservation method is proposed to eliminate false IMFs. Tests prove that improved HHT can greatly improve the accuracy of wind turbine gearbox faults diagnosis and with a balance efficiency.

Published: January 2015

Hand gesture of rotation, scaling and translation is the key problem of gesture recognition. This paper proposes a gesture recognition algorithm based on Hausdorff-like distance template matching of gesture main direction. Firstly, we segment hand gesture from video stream. Secondly, we calculate the main direction of gesture in the image, and build a 2D rectangular coordinate system. Then, we clockwise divide the gesture into eight sub-image area along the main direction of gesture and calculate the coordinates of target pixel points in each sub-image area in the 2D rectangular coordinate system. Finally, the algorithm of Hausdorff-like distance template matching is used to recognize the final gesture. Experimental results show that this algorithm can achieve real-time correct recognition of gestures in relatively stable light conditions. The overall recognition rate can reach 95%.
