Recently, I am dealing with the new biometric recognition trait, based on hand tremor signals acquired from leap motion device. You can access the latest published article from http://ieeexplore.ieee.org/document/8076840/?reload=true , doi: 10.1109/ACCESS.2017.2764471. I would like to announce the leap motion community to take into account for this project. It should be improved further with your guidance and attentions. Any one who want to participate the research group can contact wtih me via : email@example.com. Please do not hesitate asking further questions? By the way i would like to appreciate leap motion developers for producing such a valuable device. Thanks them a lot.
