Low-cost real-time 2-D motion detection based on reconfigurable computingLow-cost real-time 2-D motion detection based on reconfigurable computing Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-022006enThis paper presents a method for real-time hand motion detection in two-dimensional (2-D) space. A new input device for kinetically challenged persons that uses this method is presented. The device consists of a solid-state accelerometer that senses 2-D motion, a microcontroller that samples the data in real time, and an embedded field-programmable gate array (FPGA) device that distinguishes the types of motion from programmable motion vocabularies. The system has a quadratic capability O(n2) in detecting motions, while the hardware used has a linear-complexity O(n). The motion-detection computational model is presented, along with experimental results. The system adaptation to individual requirements and the cost versus quality tradeoff can be addressed through reconfigurationhttp://creativecommons.org/licenses/by/4.0/IEEE Transactions on Instrumentation and Measurement5562234-2243 Papadimitriou Kyprianos Παπαδημητριου Κυπριανος Dollas Apostolos Δολλας Αποστολος Sotiropoulos Stamatios Institute of Electrical and Electronics Engineers Field programmable gate arrays Motion detection Two dimensional displays Solid state circuits
