Inexpensive and Flexible Eye Gaze Tracking from Bed

Inexpensive and Flexible Eye Gaze Tracking from Bed
Presentation from the International MND Conference
Sydney, December 2011



presenter:  John Paulin Hansen, paulin@itu.dk

Javier San Augustin; Henrik Skovsgaard

Title:  In expensive and flexible gaze tracking from bed

E-Solutions to improve outcomes for people living with ALS/MND

Objective:  To present a gaze tracking system that does not occupy the physical space in front of the user.  The system applies a large display that can be seen by a group of people and it is composed of inexpensive hardware components (display, camera, IR lights and PC) that can be substituted immediately if they fail.

Dscription:  The system consists of the ITU open-source gaze tracking software that can be downloaded free-of-charge from https://mail.alsa-national.org/exchweb/bin/redir.asp?URL=http://www.gazegroup.org   This system works with an inexpensive web camera and Windows computer that has a video projector connected to it.


If you could not make the 22nd International Symposium on ALS/MND’s live, the Allied Health Professional Forum’s  sessions, they are available online for your viewing.

Visit https://mail.alsa-national.org/exchweb/bin/redir.asp?URL=http://mnda.eventstreaming.tv/ to watch these presentation that occurred on November 29 in Sydney, Australia..

To access the specific presentations on  video, you will need to enter your name, email address and the password “sydney,” all in lowercase letters. Click the “Login” button, then the specific thumbnail below the main video display screen.

This video, along with other activities that took place during the symposium, will be available until January 1, 2012; however organizers are hoping to keep this link active until January 31.  After that date, the video will be available on the MNDA Australia website at https://mail.alsa-national.org/exchweb/bin/redir.asp?URL=http://www.mndaust.asn.au.

The ALS Association thanks both MND Australia and the MND Association U.K. for making these videos available.

The Berlin Brain-Computer Interface Presents the Novel Mental Typewriter Hex-O-Spell

The Berlin Brain-Computer Interface Presents the Novel Mental Typewriter
   Hex-O-Spell

We present a novel typewriter application "Hex-O-Spell" that is specifically
tailored to the characteristics of direct brain-to-computer interaction. The
high bandwidth at which a user may perceive information from the display is
used in an appealing visualization based on hexagons. On the other hand the
control of the application is possible at low bandwidth using only two
control commands (mental states) and is relatively stable against delays and
the like. The effectiveness and robustness of the interface was demonstrated
at the CeBIT 2006 (world's largest IT fair) where two subjects operated the
mental typewriter at a speed of up to 7.6  char/min. It was developed within
the Berlin Brain- Computer Interface project in cooperation with specialists
for Human Computer Interaction.

The University of California (UC), Berkeley and UC San Francisco launched the
Center for Neural Engineering and Prostheses a year ago to take advantage of
the neurology expertise in San Francisco and the engineering skills in the
Bay Area. The center develops technologies that enable the human brain to
control electronic devices. "Medicine has not taken neural prosthetics very
seriously until recently," says center co-director Edward Chang. The neural
prosthetic devices work by connecting a device inserted into the brain
directly to a computer. The electrical signals from the brain travel through
a cable to the computer, where they are decoded into instructions for some
kind of action, such as moving a cursor. The physical technology is one of
several hurdles the researchers must overcome before the devices are truly
useful. The researchers note that some of the problems are going to require a
greater understanding of how the human brain works. A major part of the
research is determining what devices would actually be useful to patients. "I
want to find out what are the things that are going to be most useful for
people, and it may be as simple as communication," Chang says.

“[This] is a remarkably well edited and organized book prepared by Jonathan and Elizabeth
Wolpaw. It is not simply a patchwork of 25 chapters…[but] rather, each chapter provides
an overview of its main topic, adds its message to the key issues discussed by others,
poses questions that still need to be addressed, and looks to the near future. The Wolpaws
establish the foundational issues in an introductory chapter and nicely finish with a summary
of those issues, as well as a sober examination of the future of BCI science and applications….
Brain-Computer Interfaces
is a very fine and readable resource to catch up on the
accomplishments, needs, and promise of this technology.”
--Bruce H. Dobkin, MD, Professor of Neurology, Director, Neurologic Rehabilitation and Research
Program, University of California Los Angeles, Geffen/UCLA School of Medicine, Los Angeles, CA

“[The Editors] are in a unique position to oversee the authoritative and complete coverage of
the field, a journey they take us through with the collaboration of other experts. Indeed, this
is the first book, not only to present a unified perspective of the entire spectrum of topics
in brain-computer interfaces, but also to redefine the field. Moreover, this is a much-needed
textbook that I was waiting for. No doubt, it will become an indispensable source for every
practitioner --newcomers, students and researchers alike.”

--Dr. José del R. Millán, Defitech Professor, Defitech Chair in Non-Invasive Brain-Machine
Interface, Center for Neuroprosthetics, Ecole Polytechnique Fédérale de Lausanne (EPFL),
Switzerland

Brain-Computer Interfaces: Principles and Practice
coverage provides an introduction to and summary of all aspects of BCI research and development: from brain anatomy to electrode technologies; from signal processing to clinical applications; from business dissemination models to ethical issues. The chapters are written by recognized experts in each of the fields relevant to BCI technology and they are coordinated into a logical whole with a didactic format and style accessible to all
is a comprehensive and authoritative presentation of the current state of brain-computer interface (BCI) research and development. This book is accessible to readers with basic undergraduate-level background in biology, physics, and mathematics, and is aimed at scientists, engineers, and clinicians at all levels from advanced undergraduates upward. Its uniquely comprehensive and balanced
readers.

The book can serve as the basis for graduate-level courses in BCI research and development, and as a resource for experienced BCI researchers or others interested in BCI research and its applications. The book’s goal is to provide a diverse range of readers with the broad knowledge needed to interact productively with others from the many disciplines involved in BCI research and development. By enabling people from many different disciplines to work together effectively, this book makes a unique and important contribution to a burgeoning new research field.

Improving Brain Function
 

Braindeck-non invasive EEG & BCI that could provide new control channel for ppl w/ ALS

BrainDeck

People who have severe movement disorders like Amyotrophic Lateral Sclerosis
(ALS) or Locked in Syndrome, is a condition where a patient is awake and
aware of its surrounding but unable to communicate or perform any action due
to paralysis of almost every voluntary muscles in the body (with the
exception of eye movements and blinking). Imagine patients having a fully
functional brain trapped within a non-functioning body. The brain of the
patient would be fully conscious and aware of its surroundings, it could
think and process stimuli, but unable to translate thought into action. This
is caused by a gradual degeneration of the nerve cells in the central nervous
system that controls voluntary muscle movement.

Therefore the author suggest a non invasive Electroencephalogram (EEG) based
Brain Computer Interface (BCI) that could provide a new control channel to
individuals with severe motor impairments, an application that would enable
individuals to communicate with the outside world. The non-invasive method of
BCI suggested by the author is considered a safe procedure as it requires no
brain surgery and causes no harm to the patient under any circumstance.

Here, we see a subject trying to send an email through brain activity using a
T9 suggestive text approach (reduce stress). This is a low cost solution as
it makes use of a commercial EEG acquisition, Thus the time taken to send an
email is less compared with making use of the P300 approach.
