Gesture Recognition and Control Part 3 - WiFi Oriented Gesture Control & its application

This Exploratory Survey paper explore the basic princip le behind Wi F i oriented Gesture Control System. The paper briefly provided the literature review about this latest technology. That is technology having vast applications in real time situation like in Gaming, Home automation, Medicine for disabled & latest electronic gadgets. The researcher from University of Washington has done a miles tone work for this technology . I t will be expected that i n 2020 era, th e W i F i based Gesture Control & Recognition system replace all other Man - Machine interface methods

Anti-Fall: A Non-intrusive and Real-time Fall Detector Leveraging CSI from Commodity WiFi Devices

Fall is one of the major health threats and obstacles to independent living for elders, timely and reliable fall detection is crucial for mitigating the effects of falls. In this paper, leveraging the fine-grained Channel State Information (CSI) and multi-antenna setting in commodity WiFi devices, we design and implement a real-time, non-intrusive, and low-cost indoor fall detector, called Anti-Fall. For the first time, the CSI phase difference over two antennas is identified as the salient feature to reliably segment the fall and fall-like activities, both phase and amplitude information of CSI is then exploited to accurately separate the fall from other fall-like activities. Experimental results in two indoor scenarios demonstrate that Anti-Fall consistently outperforms the state-of-the-art approach WiFall, with 10% higher detection rate and 10% less false alarm rate on average.Comment: 13 pages,8 figures,corrected version, ICOST conferenc
