Improving Eye Motion Sequence Recognition Using Electrooculography Based on Context-Dependent HMM
2016
Computational Intelligence and Neuroscience
Preserved Fulltext
In this paper, we propose a context-dependent hidden Markov model- (HMM-) based EOG modeling approach that uses separate models for identical eye motions with different contexts. ...
Additionally, we propose a method of user adaptation based on a user-independent EOG model to investigate the trade-off between recognition accuracy and the amount of user-dependent data required for HMM ...
In this work, we improve HMM-based eye motion recognition to achieve higher recognition accuracy for continuous eye motion input. ...

For recognition purposes, the proposed system first detects eye movements using electrooculography (EOG), and then a hidden Markov model (HMM) is applied to model the EOG signals and recognize the eye-written ...
Additionally, this paper investigates an EOG adaptation that uses a deep neural network (DNN)-based HMM. ...
Then, we modeled these motions using a context-dependent model. ...
