Is there music in Heaven? Van Morrison flowing “Into the Mystic”? Eva Cassiday singing about the “Songbird”? A Vanilla Ice concert, no then I would know for sure I was in the other place.
I would like to hear some of your ideas.
My back has decided to remind me of my advancing years. :) Nothing major, just a few days off my feet. Siting in a chair, or in a car, does aggravate it so I will be taking a few days off from blogging.
The novel system allows individuals with disabilities to operate a computer, control a powered wheelchair and interact with their environments simply by moving their tongues.
“This device could revolutionize the field of assistive technologies by helping individuals with severe disabilities, such as those with high-level spinal cord injuries, return to rich, active, independent and productive lives,” said Maysam Ghovanloo, an assistant professor in the Georgia Tech School of Electrical and Computer Engineering. Ghovanloo developed the system with graduate student Xueliang Huo.
The tongue-operated assistive technology, called the Tongue Drive system, was described on June 29 at the 2008 Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) Annual Conference in Washington, D.C. An article about this system is also scheduled to appear in an upcoming issue of the Journal of Rehabilitation Research and Development. This research was funded by the National Science Foundation and the Christopher and Dana Reeve Foundation.
To operate the Tongue Drive system, potential users only need to be able to move their tongues. Attaching a small magnet, the size of a grain of rice, to an individual’s tongue by implantation, piercing or tissue adhesive allows tongue motion to direct the movement of a cursor across a computer screen or a powered wheelchair around a room.
“We chose the tongue to operate the system because unlike hands and feet, which are controlled by the brain through the spinal cord, the tongue is directly connected to the brain by a cranial nerve that generally escapes damage in severe spinal cord injuries or neuromuscular diseases,” said Ghovanloo, who started working on this project about three years ago at North Carolina State University. “Tongue movements are also fast, accurate and do not require much thinking, concentration or effort.”
Movement of the magnetic tracer attached to the tongue is detected by an array of magnetic field sensors mounted on a headset outside the mouth or on an orthodontic brace inside the mouth. The sensor output signals are wirelessly transmitted to a portable computer, which can be carried on the user’s clothing or wheelchair.
The sensor output signals are processed to determine the relative motion of the magnet with respect to the array of sensors in real-time. This information is then used to control the movements of a cursor on the computer screen or to substitute for the joystick function in a powered wheelchair.
The system can potentially capture a large number of tongue movements, each of which can represent a different user command. A unique set of specific tongue movements can be tailored for each individual based on the user’s abilities, oral anatomy, personal preferences and lifestyle.
“An individual could potentially train our system to recognize touching each tooth as a different command ,” explained Ghovanloo. “The ability to train our system with as many commands as an individual can comfortably remember is a significant advantage over the common sip-n-puff device that acts as a simple switch controlled by sucking or blowing through a straw.”
The Tongue Drive system is also non-invasive and does not require brain surgery like some of the brain-computer interface technologies.
Ghovanloo’s group recently completed trials in which six able-bodied individuals tested the Tongue Drive system. Each participant defined six tongue commands that would substitute for computer mouse tasks – left, right, up and down pointer movements and single- and double-click. For each trial, the individual began by training the system. During the five-minute training session, the individual repeated each of the six designated tongue movements 10 times.
During the testing session, the user moved his or her tongue to one of the predefined command positions and the mouse pointer started moving in the selected direction. To move the cursor faster, users could hold their tongue in the position of the issued command to gradually accelerate the pointer until it reached a maximum velocity.
Results of the computer access test by novice users with the current Tongue Drive prototype showed a response time of less than one second with almost 100 percent accuracy for the six individual commands. This is equivalent to an information transfer rate of approximately 150 bits per minute, which is much faster than the bandwidth of most brain-computer interfaces, according to Ghovanloo.
The researchers have also tested the ability of twelve able-bodied individuals to operate an electric-powered wheelchair with the Tongue Drive system. The next step is to test and assess the usability and acceptability of the system by people with severe disabilities, said Ghovanloo. He is teaming with the Shepherd Center, an Atlanta-based catastrophic care hospital, and the Georgia Tech Center for Assistive Technology and Environmental Access, to conduct those trials.
The research team has also begun to develop software to connect the Tongue Drive system to a wide variety of readily available communication tools such as text generators, speech synthesizers and readers. In addition, the researchers plan to add control commands, such as switching the system into standby mode to permit the user to eat, sleep or engage in a conversation while extending battery life.
“We hope this technology will reduce the need of individuals with severe disabilities to receive continuous assistance from family members or caregivers, thus significantly reducing healthcare and assistance costs,” noted Ghovanloo. “This system may also make it easier for them to work and communicate with others, such as friends and family.”
A couple in Sweetwater , Texas , had a lot of potted plants. During a recent cold spell, the wife was bringing a lot of them indoors to protect them from a possible freeze. It turned out that a little green garden grass snake was hidden in one of the plants. When it had warmed up, it slithered out and the wife saw it go under the sofa.
She let out a very loud scream. The husband (who was taking a shower) ran out into the living room naked to see what the problem was. She told him there was a snake under the sofa.
He got down on the floor on his hands and knees to look for it. About that time the family dog came and cold-nosed him on the behind. He thought the snake had bitten him, so he screamed and fell over on the floor.
His wife thought he had had a heart attack, so she covered him up, told him to lie still and called an ambulance. The attendants rushed in, would not listen to his protests, loaded him on the stretcher, and started carrying him out.
About that time, the snake came out from under the sofa and the Emergency Medical Technician saw it and dropped his end of the stretcher. That’s when the man broke his leg and why he is still in the hospital.
The wife still had the problem of the snake in the house, so she called on a neighbor who volunteered to capture the snake. He armed himself with a rolled-up newspaper and began poking under the couch. Soon he decided it was gone and told the woman, who sat down on the sofa in relief.
But while relaxing, her hand dangled in between the cushions, where she felt the snake wriggling around. She screamed and fainted, the snake rushed back under the sofa. The neighbor man, seeing her lying there passed out, tried to use CPR to revive her.
The neighbor’s wife, who had just returned from shopping at the grocery store, saw her husband’s mouth on the woman’s mouth and slammed her husband in the back of the head with a bag of canned goods, knocking him out and cutting his scalp to a point where it needed stitches.
The noise woke the woman from her dead faint and she saw her neighbor lying on the floor with his wife bending over him, so she assumed that the snake had bitten him. She went to the kitchen and got a small bottle of whiskey, and began pouring it down the man’s throat.
By now, the police had arrived. They saw the unconscious man, smelled the whiskey, and assumed that a drunken fight had occurred. They were about to arrest them all, when the women tried to explain how it all happened over a little green snake. The police called an ambulance, which took away the neighbor and his sobbing wife.
Now, the little snake again crawled out from under the sofa and one of the policemen drew his gun and fired at it. He missed the snake and hit the leg of the end table. The table fell over, the lamp on it shattered and, as the bulb broke, it started a fire in the drapes.
The other policeman tried to beat out the flames, and fell through the window into the yard on top of the family dog who, startled, jumped out and raced into the street, where an oncoming car swerved to avoid it and smashed into the parked police car.
Meanwhile, neighbors saw the burning drapes and called in the fire department. The firemen had started raising the fire ladder when they were halfway down the street. The rising ladder tore out the overhead wires, put out the power, and disconnected the telephones in a ten-square city block area (but they did get the house fire out).
Time passed! Both men were discharged from the hospital, the house was repaired, the dog came home, the police acquired a new car and all was right with their world.
A while later they were watching TV and the weatherman announced a cold snap for that night. The wife asked her husband if he thought they should bring in their plants for the night.
And that’s when he shot her.

It is further proof that breastfeeding promotes the maternal bond through a biochemical process.
The team at Warwick University said the hormone oxytocin was known to be released during breastfeeding but the mechanism in the brain was unclear.
Oxytocin also produces contractions during labour and causes milk to be “let down” from the mammary glands.
The hormone is produced in the hypothalamus – the part of the brain that controls body temperature, thirst, hunger, anger and tiredness.
It has been shown to promote feelings of trust and confidence and to reduce fear. “
Seeing a women breast feed their child in public “freaks” out some people. I think is a very natural act and even find it inspiring to see the look of love on the face of a mother sharing her body with her child.
Do you think women should not be allowed to breastfeed their child in public? Why?
3) Some final words on love. Excerpts from “Song” by Allen Ginsberg
“the weight, the weight we carry is love.”
“No rest without love, no sleep without dreams of love – no mad or chill, obsessed with angels or machines, the final wish is love – cannot be bitter, cannot deny, cannot withhold if denied”
“The warm bodies shine together in the darkness, the hand moves to the center of the flesh, the skin trembles in happiness and the soul comes joyful to the eye”
