    Abstract— The most advantage of FPGA is its hardware/software co-design. Based on this advantage, we can make full use of hardware pipeline, multi-core architecture, hardware acceleration technologies to accelerate their applications, in order to mitigate or completely solve high real-time, multi-tasking, big data and a series of other problems. This design aims at completely achieving a 3D Motion Sensing Game System on the FPGA platform. The game system has to support voice and image output, and collects the real-time in-motion data wirelessly through sensors in the mobile phone to produce human limb movement instruction for game control.This system is multi-tasking, massive data and strict real-time. The final results show that the game system designed with FPGA technology, not only runs smoothly, fast response time, but also has good scalability, the ability to easily maintain and upgrade, and therefore has a very good prospect.

    Abstract—In this paper, an intelligent wheelchair control system which can provide auxiliary help for disabled patients based on BCI is proposed. This system is based on 90% of normal brain function people whose αwave amplitude of EEG can be significantly enhanced in the short eyes closed. We place two detection electrodes on the occipital and forehead of the brain, pre-amplify the detected signal, and then after a series of signal processing, we can simply and easy control the movement of the electric wheelchair and do not need training or only a small amount of training. Through the TI’s ADS1198 analogy front-end circuit, we realize EEG acquisition, amplification, isolation and data pre-processing. Data is processed in the Nios II environments. Finally, the system controls the YIFUCON’s wheelchair KB5618 in accordance with the appropriate action.

  • 012  Electric Unicycle from Image Signals

    Abstract— This paper realizes a SoPC system which balances an electric unicycle based on image data from a CMOS camera. Generally, tilt-meters and gyros have commonly been chosen to measure the tilt angle and angle rate of a unicycle. In this paper, a CMOS camera is employed as the tilt angle measurement sensor instead. Through simple image processing techniques, a hardware circuit module for inclination measurement for the unicycle is implemented on the FPGA of a SoPC. By the concept of software hardware co-design, the inclination measurement module is integrated with the double-PD control method on the SoPC to balance the unicycle. Simulation and experimental results confirm that the resulting system meets the design goal.
    Keywords— SoPC, FPGA, electric unicycle, double-PD control

    School of software and Microelectronics, Peking University

    Abstract— We describe a light field display able to present 3D graphics to multiple viewers around the display. The display consists of a high-speed DLP projector, a spinning mirror and FPGA circuitry to decode specially rendered HDMI video signals. The display uses a customized Nios II processor to rendering 1440 images per second 3D graphics, projecting onto spinning display with 3.75 degree separation up to 15 updates per second.

    Guangdong Province, Guangzhou Higher Education Mega Centre, South China normal university

    Abstract— Dimensional mechanical arm is an important development direction of mechanical arm, which plays a significant role in the industrial and agricultural production. The system is developed based on the platform DE2, which makes full use of FPGA hardware structure and Nios II flexible embedded processing capability. The mechanical arm motion is simplified through analysis of multi-dimension manipulator motion. The related control algorithm and hardware driver are implemented to copy Chinese calligraphy as well as accomplish Chinese calligraphy action as lifting and pressing, writing sketches and other functions. The experiment results proved the efficiency of the design.

    Abstract— This work uses a SoPC platform as the flight controller of a quad-rotor aircraft. By CAD/CAM technologies the fuselage of the aircraft is built. The posture of the aircraft is stabilized according to the sensory data from a three-axle gyroscope and a tri-axia accelerometer. Additionally, a CMOS camera mounted on the bottom of the aircraft and an ultra-sonic sensor enables it to detect and track the object of interest on the ground while the aircraft is flying.

  • 016  TDTOS – T-shirt Design and Try-On System

    Department of Electrical Engineering, National Taiwan University

    Abstract— In this paper, a new framework for T-shirt design and try-on simulation based on FPGA is presented. Users can not only gain realistic try-on experience, but also design the T-shirts all on their own. The design approach of this system consists of three major parts. First, collect relevant information from the camera and identify the position of the clothes. Second, process the retrieved data and modulate the color of the clothes with folds and shadows remained. Third, place built-in or user-designed pictures onto the clothes and simulate their deformation while the user moves arbitrarily. In comparison with existing virtual clothes fitting systems, our system provides the flexibility of designing customized pictures on the T-shirt with realistic virtual try-on simulation in real-time.
    Keywords— virtual clothes try-on, T-shirt design, augmented reality, virtual fitting room, FPGA design
