Applying Probabilistic Classification Vector Machines in Self-paced BCI to Enhance Foot Movement Detection

Rahele Mohammadi; Ali Mahloojifar

Volume 7, Issue 1 , June 2013, , Pages 39-55

  A critical issue in designing a self-paced brain computer interface (BCI) system is onset detection of the mental task from the continuous electroencephalogram (EEG) signal to produce a brain switch. This work shows significant improvement in a movement based self-paced BCI by applying a new sparse learning ...  Read More

Kinematical Modeling of the Writing Process using Model Predictive Control

Mehdi Borjkhani; Farzad Towhidkhah

Volume 4, Issue 2 , June 2010, , Pages 109-122

  Writing is one of the high practiced and complex movement skills of human. Most of the proposed models for writing are bottom-up models, and therefore they could not reflect the biological aspects of movements in this process. Also there is not any model for illustrating the role of different parts of ...  Read More

Power Law: Relation Between Geometry And Kinematics In Skilled Drawing Movements

Saeed Rashidi; Seyed Mohammad Reza Hashemi Golpayegani; Ali Fallah; Farzad Towhidkhah

Volume 4, Issue 1 , June 2010, , Pages 33-44

  In drawing movements, the constraints imposed on the trajectory geometry properties and kinematics are known with two laws: 2/3 power law and isochrony phenomenon. In this paper experiments have been designed to study the relation between two empirical laws in straight and curved patterns of drawing ...  Read More
