Human computer interaction (HCI) is a classic topic, and hand gesture is one of the most natural languages, so the key point in human computer interaction is hand gesture recognition. A skin color model based on Hue is utilized to detect skin color regions like hands. To distinguish the face and hand, a simple and fast hand segmentation algorithm is developed. Moreover, we use the least square method...

In recent years, mobile devices and applications have known a growth that is unprecedented in any other technological field, reaching virtually all aspects of our lives including sports, leisure, social relationships or health. This paper describes the development of an environment to assess auditory emotional recognition based on a mobile application. The primary aim of this work is to provide a...
In software security testing, fuzz testing and symbolic execution are two main testing techniques. Fuzz testing finds program bugs by executing the target program with random inputs it generates while monitoring the execution for abnormal behaviors. Though fuzz testing is able to explore deep into a program's state space efficiently, it usually cannot guarantee the code coverage ratio in many situations...
Attribute Topology (AT) is a simple and visual representation method of formal concept. By AT, the formal concept can be computed visually and parallel. Attribute partial ordered structure diagram (APOSD) is based on the partial order relationships in math and focus on the cover and inclusion among attributes. Although AT and APOSD have already achieved mutual transformation, the definition and characteristics...
In this paper, we discuss the problem on the construction of asymmetric quantum codes [[n, k, dz/dx]]4 from primitive narrow sense BCH codes. Take advantage of dual containing BCH codes of length n = 4m -- 1 where m = 2l and m = 2l + 1, we construct two families of new asymmetric quantum codes with dz ≥ δmax + 1, where δmax is the maximal designed distance of dual...
In order to enhance the timeliness and accuracy of active yaw moment control for electric-wheel vehicle, an improved AYC system was designed. The control logic of the improved AYC system was based on identification of road adhesion coefficient. The control logic threshold value included three ranges. The controller of the improved AYC system adopted an integral separation PID controller in order to...

Then the hardware and software design of the system are mainly expatiated in detail. Practical application...
Angle measurement is the key technology of digital control and angular position tracking in servo system. For the problem of low accuracy of angle measurement and error in coarse-fine data coupling, data fusion was applied in the double-channel angle measurement system. The angle was simultaneously measured by coarse channel and fine channel, then the coarse data and fine data was coupled by data...

These related applications not only make our lives more convenient and efficiency, but also reduce the overhead costs. Users can more naturally, quickly and intuitively convey commands through different types of HCI applications to computer. Leap Motion1 is used to capture the information of...
Magnetic tape storage has been used for recording audio, video, instrumentation, and computer data. The medium can record a large amount of data on winding tape and recorded data are reliable and stable. However, the performance of the other storage media, such as optical disc, magnetic disk, and integrated circuit memory, has progressed remarkably, so the advantage of tape storage has decreased....
In this paper, we present an application that dance and music using Microsoft Kinect sensor and use MIDI technology to make a visual instrument for somebody who interested in music. The program will draw a sphere in three dimensions space by OpenGL and a user can dance in the visual sphere. The user can trigger events by entering two hands or feet in a specific zone and events will generate music...
