Design and simulation of virtual telephone keypad control based on brain computer interface (BCI) with very high transfer rates

Abstract

Brain Computer Interface (BCI) is a communication and control mechanism, which does not rely on any kind of muscular response to send a message to the external world. This technique is used to help the paralyzed people with spinal cord injury to have the ability to communicate with the external world. In this paper we emphasize to increase the BCI System bit rate for controlling a virtual telephone keypad. To achieve the proposed algorithm, a simulated virtual telephone keypad based on Steady State Visual Evoked Potential (SSVEP) BCI system is developed. Dynamic programming technique with specifically modified Longest Common Subsequence (LCS) algorithm is used. By comparing the paralyzed user selection with the recent, and then the rest, of the stored records in the file of the telephone, the user can save the rest of his choices for controlling the keypad and thence improving the overall performance of the BCI system. This axiomatic approach, which is used in searching the web pages for increasing the

A Brain Controlled Command-Line Interface to Enhance the Accessibility of Severe Motor Disabled People to Personnel Computer

“…By assessing the amplitude of the P300 response after each flash, the target cell is determined as the intersection of a row and a column that elicit the most significant P300. Extensive progress was made in developing other attractive applications, such as transmitting digits over the Internet [ 18 ], navigating the virtual world [ 19 ], virtual keyboard [ 20 ], controlling the robot via Internet [ 21 ], controlling an electric Car [ 22 ], phone keypad [ 23 ], and 2-D cursor [ 24 ]. These studies suggested a P300 BCI system allowing severely motor-disabled people to submit system commands to the operating system for execution.…”

Online LDA based brain-computer interface system to aid disabled people

“…The system tested on 8 subjects could convey 4 type of commands; left, right, top and bottom (Postelnicu, Talaba, & Toma, 2011). In 2011 Ashari et al developed BCI based virtual telephone keypad that relies on SSVEP (Ashari, Al-Bidewi, & Kamel, 2011). In 2012 Kaufmann et.…”

An Experiment of Ocular Artifacts Elimination from EEG Signals using ICA and PCA Methods

“…Applications of EEG in the medical field are also able to determine the treatment to patients who have diseases related to nerves. In the development of BCI, EEG signals are used to move the cursor in two dimensions [7,8], to design a virtual keyboard [9,10], to move the three-dimensional simulations [11][12][13][14], and to design a mobile robot for users who have a physical or mental deficiency [2][3][4].…”
