Eye-tracking technology has been around for years, most notably in use for eye-tracking software and heat mapping for website conversion optimization, but it’s never really entered the mainstream market, until now.

Tobii Technology has developed technology that allows the full control of a laptop just by the gaze of the user’s eyes.

Tobii has been a player in the eye-tracking and gaze interaction industry since 2001. In the early days, sight technology was cumbersome, preventing a user from moving when using eye-tracking software. The company eventually overcame that obstacle and has continued to innovate on the idea of remote eye-tracking in different use cases.

“It was the first true remote experience, the first eye tracker that you could actually move and walk away from,” said John Elvesjö, executive vice president and founder of Tobii, explaining the breakthrough.

It was a powerful development for many markets, especially for disabled individuals without the use of their hands, who could now use a computer in a much more effective way.

The technology has continued to evolve. For instance, the software can now gauge how well a user is paying attention and remembering online advertising, Elvesjö said.

“We can take a look at the accumulated gaze time or attention that you’re getting [on an online ad], which can also be determined by other metrics, like how long before they actually looked at your message for the first time,” he said. “Also, if a person looked at the ad, looked away and then looked back in a specific period of time, which is what we would refer to as a declaration of interest. It’s a way for us to judge some of the key characteristics of an online ad.”

The mass market use of Tobii’s technology aims to allow computer users to browse the web simply by directing their gaze using a Tobii integrated laptop or a standalone module added to your PC.
For instance, if they are scrolling through a website and their eyes focus at a specific place of the page then scrolling will stop to allow them time to read and interact with the content. The technology can also help conserve power — if any monitor isn’t being looked at, the technology will dim the screen until it is in use again.

According to Mashable, this technology, called REX, is still being developed, but once released, will be available through the USB port of any Windows-based PC. Tobii plans to also provide this technology for Apple AAPL -1.04% products in the future.

Elvesjö stressed that they aren’t eliminating the need for a keyboard but want to improve the experience of browsing, gaming, and using software like the Microsoft MSFT -1.35% Suite. He said it will also help those with special needs and empower marketers to better understand the interaction with their online ads.

“We want to increase the bandwidth between the human and the machine,” Elvesjö said. “Literally making the machine more intelligent to make interaction faster and easier.”

Electronic Eye Gaze Communication Options for People with ALS

Electronic Eye Gaze Communication Options for People with ALS



There are various types of electronic eye gaze options for people with ALS.  These systems rely on eye movement to “activate” a letter on a computer screen in order for the letter to be typed.  In order for the system to work reliably, the person with ALS needs to have upper and lower and lateral eye movements.   This article will describe the various options for eye gaze technology including insurance funded devices and DIY (Do It Yourself) devices.

Insurance funded systems

For more sophisticated computer access there are several “eye gaze” computer systems on the market.  These high priced specialty computers rely strictly on eye movement for activation.  This type of machine is only used by people that have little or no muscle movement left on their bodies. The basic premise is that a CCTV camera is placed below a computer monitor.  The camera tracks your retina movement.  Special software is loaded into the computer and allows the user to have full access by simply moving their eyes around the screen. 

Insurance will only fund an eye gaze system if the speech therapist writing the report can document no other forms of access will work with the client.  Most insurance companies (including Medicare and some private insurance providers) will fund 80% of the cost of this device.  However, following Medicare guidelines, people enrolled in hospice or living at an assisted living facility are NOT eligible for communication devices. This often leads to frustration for many PALS since they now need the eye gaze systems but can’t get them funded. There are now other options on the market which are described later in this document.

Producers of eye gaze systems are:



LC Technologies (www.eyegaze.com)

Prentke Romich Company, (www.prentrom.com)

Tobii (www.tobii.com)

 

 

 

 

Other Eyegaze Options (most are not fundable via insurance but it never hurts to ask)

The Eye Tribe $99.00 (http://theeyetribe.com) Not yet available—company taking pre-orders. Expected shipment date December 2013.

The Eye Tribe software enables eye control on mobile devices, allowing hands­free navigation of websites and apps; incl. eye activated login, enhanced gaming experiences and cloud­based user engagement analytics. The Eye Tribe intends to become the leading provider of eye control technology for mass market consumer devices by licensing the technology to manufacturers.

It all started seven years ago where the four founders meet at the IT University of Copenhagen. The ambition was to make eye tracking available for everyone at an affordable price. Within a couple of years they were renowned as the world leading research group in low cost eye tracking. After finishing their PhD’s the four founders bought the IP from the University and formed The Eye Tribe company during their participation in the European StartupBootcamp accelerator program in 2011. The team now includes 16 full time employees, building eye tracking software and applications for mobile devices. The Eye Tribe received seed funding of USD 1 million from private European investors in 2012 and is also leading a USD 4.4 Million government funded project to develop eye control for mobile devices.

The EyeWriter Project (a Do It Yourself Kit—the blueprints are free and cost of materials is about $100.00. http://www.eyewriter.org)

Members of Free Art and Technology (FAT), OpenFrameworks, the Graffiti Research Lab, and The Ebeling Group communities have teamed-up with a legendary LA graffiti writer, publisher and activist, named TEMPTONE. Tempt1 was diagnosed with ALS in 2003, a disease which has left him almost completely physically paralyzed… except for his eyes. This international team is working together to create a low-cost, open source eye-tracking system that will allow ALS patients to draw using just their eyes. The long-term goal is to create a professional/social network of software developers, hardware hackers, urban projection artists and ALS patients from around the world who are using local materials and open source research to creatively connect and make eye art.

PCEye by Tobii $3,900.00 .  (http://www.tobii.com/pceye) 

The Tobii PCEye Go is a peripheral eye tracker that enhances computer accessibility with the speed, power and accuracy of gaze interaction. The device replaces the standard mouse, allowing you to navigate and control a desktop or laptop computer using only your eyes. You place this device on your EXISTING computer so no other hardrive is required.  The PCEye Go runs on standard Windows computers and tablets, allowing you to work with any application that is normally controlled by a standard computer mouse or through touch. Surf the web, connect with friends online, play games, Skype, use environmental controls to turn on the lights or TV and even make spreadsheets and documents by using your eyes.

The PC Eye can also be used on any WINDOWS TABLET and will turn that tablet into an eye gaze system. 

VT2Mini by Eye Tech Ditigal Systems (https://www.eyetechds.com/vt2-mini.shtml)

With the simplicity of a single USB interface, the VT2 mini offers compactness and the largest head motion box for reliable and accurate data collection. Easily swapped between laptops, tablets or desktop computers, we include the QuickCAPTURE gaze analysis software and QuickLINK API to allow researchers and developers access to valuable metrics such as gaze position, dwell times, blink rates, pupil size, and much more.

Vision Key (http://www.eyecan.ca) $4,000

VisionKey is the latest in eye controlled communication and enables users with severe physical disabilities to type and talk with their eyes. Lightweight and head mounted, VisionKey gives users communication independence and control in their lives by simply "looking". The system also gives them each a voice by enabling them to control a speech synthesizer in the VisionKey unit or on the computer. Now users can write letters, play games, surf the net and listen to multi-media sound just by moving their eyes. VisionKey combines a viewer mounted on a pair of standard frames with a small control unit. An eye tracker and a microcomputer measure the position of the eye and when a selection is made, it appears on the control unit LCD and on the computer. Users look at a specific word, letter or character on the chart in front of their eye and "type" by holding their gaze until a selection is confirmed by a green highlight and a beep.

 

The research into electronic eye gaze devices continues to develop at an amazing speed.  As new technology emerges, additions will be made to this list.

Hands Free Access to the iPad via Switch Activation

Apple's new operating system, the iOS7 enables users to access their iPhone, iTouch, and iPad without having to use their hands to touch the screen.  The new operating system allows switch access to Apple's line of tablets.  If you have questions about switch access to the iPad, I am happy to help--email me at abrownlee@alsa-national.org

In order to use the iPad with a switch you will need:
 
1. iPad (or iPhone, iTouch) with iOS7
2. Bluetooth Switch or Bluetooth Switch Interface
 
Optional: Mounting (to secure the iPad to a wheelchair, table, etc...)  Mounting options available at www.rjcooper or www.blueskydesigns.com
 
What is a switch?
 
A switch controls an electronic device--it sends a current to the machine to do something.  For example, a joystick on a power wheelchair is a switch--when activated, it sends a current to the driving mechanism to go forward, back, left, right.  A switch does the same thing with a communication device--sends a current to the electronic device to do something.  In this case, the switch makes the iPad scan--row, row, row, column, column, column until it comes to the icon you want then the users hits the switch. 
 
Switches are at the core of access technology. What can appear to some as simply a "button" can —properly selected and installed—open worlds of access to communication devices, environmental controls, computer software, and mobile devices. (source: Ablenet)
 
Switches come in a variety of shapes and sizes.  The type of switch that a user needs depends on what muscle movement they have to activate the switch.  The iPad relies on a Bluetooth interface to use a switch with the device.  This means the user has to be utilizing a Bluetooth switch or have a Bluetooth switch interface. 
 
Bluetooth switches are available at:
 
AbleNet
http://www.ablenetinc.com/Assistive-Technology/iPad-iPhone-and-iPod-Accessories-Apps/Blue2%E2%84%A2-Bluetooth%C2%AE-Switch
 
RJ Cooper
http://www.rjcooper.com/bluetooth-switch-interface/index.html
 
Inclusive TLC
http://inclusivetlc.com/Products/ViewProduct.aspx?psid=364&gpid=353
 
 
After choosing the appropriate switch, you now need to sync it to the iPad.  The following information is from Spectronics.

Switching it up in iOS 7

Via http://www.spectronicsinoz.com/blog/apps-and-mobile-learning/accessibility-and-access/switching-it-up-in-ios-7 by by Charlene Cullen      
          
The one feature I was really excited about in iOS 7 was the long awaited switch control that Apple has now built into the operating system. As with all first releases there are sure to be some tweaks and further adjustments but I’d have to say I have enjoyed exploring the options for using a switch to access the iPad. I think they will offer people with physical disabilities some great options.
You can find it in the Settings app under General, Accessibility and then Switch Control.

Switch Control
 

My first big tip if you wish to demonstrate switch control is that you need to be able to exit quickly if you need to. You can set this up in Accessibility settings. Scroll to the very bottom and select Accessibility Shortcut (which used to be Triple Click Home). Choose Switch Control so that it has a little check mark next to it. This means that you can triple click the home button and escape from switch control at any time. Now you’re ready to explore!

You have 3 options for the access method in switch control. You can choose from using the screen as a switch, using your head movement or using an external switch. We’ll be focussing on using an external switch but I’d encourage you to play with the other settings. Using left and right head movement is definitely pretty cool to try out!

It’s possible to use 1 switch with Auto Scanning or set up 2 switches for step scanning but make sure that your iPad is paired to a Bluetooth switch interface first. If you’re wondering which interfaces are compatible with iOS7, I’ve tested the Applicator with the new iOS 7 switch control and have also seen several videos with other switch interfaces such as the new Blue2 Bluetooth Switch and the Tecla DOS This is an external link.

Ablenet has put together a couple of great videos that explain switch set up in iOS 7 switch control. This one shows configuration for single switch auto scanning with the new Blue2 interface.


This video shows the new Blue2 interface and setting up iOS 7 Switch Control with Dual Switches with Step Scanning.



Christopher Hills (who, by the way, will be presenting “One Switch, One Head, the World” at our Spectronics Inclusive Learning Technologies conference in May 2014) has created a quick video where he is using the Tecla DOS with iOS7 switch control


And finally, you can see a range of videos on the Accessibility features by Luis Perez, including this
one on the new switch control.


I think that the switch control in iOS 7 has radically changed the access to the iPad home screen and apps. You can now use a switch to navigate and turn pages within iBooks or take a picture/video with the Camera app. The iOS 7 switch control will work across all of the apps that come with the iPad. I also love that there is a menu that pops up that you can scan and select gestures to zoom, pinch and swipe along with access to some other system features.
Some people have already been asking about the apps that will work with iOS 7 switch control. This will be ever changing. Some app developers have been on the ball and already made their apps compatible with iOS 7 switch control. We will need to wait for some others to catch up! I just checked out Facebook and was able to use the switch to scroll through my news feed and post a status.

The apps that were already made switch accessible by their developers, within the switch settings of the app itself, will still work with a switch interface. See Jane Farrall and Alex Dunn’s list of switch accessible apps here This is an external link. They do not all necessarily work with iOS 7 switch control. However, you can use your Bluetooth interface to work across both if you have one that is flexible enough.
You can always contact us if you have further questions about switch control with the iPad. And let us know about your success stories with using iOS 7 switch control too!

Banking on your voice: Machine stores speech for patient's future use

Banking on your voice: Machine stores speech for patient's future use



— The Miami Herald
                
— Carole Shearn isn't quite sure when she will lose the ability to speak, but she is sure of one thing: Her voice will still be heard, even when the words can no longer be spoken from her lips.
The 70-year-old West Palm Beach, Fla., resident was diagnosed with ALS, also known as Lou Gehrig's disease, last October. Her form of ALS weakens the throat muscles first.

The progressive disease has no cure, but at the University of Miami Miller School of Medicine's Department of Otolaryngology, Shearn is the first patient to take part in voice banking - a program where patients who will eventually lose their voice due to diseases such as Parkinson's, ALS and cancer - can record key words, phrases and personalized messages to communicate when speaking is no longer an option.

Shearn uses Tobii Assistive Technology, a speech-generating device, which stores her recordings into categories. She can then use a mouse, touch the screen or even use her eyes to retrieve the sound files.

In case of an emergency, Shearn has even programmed a message saying "get help immediately" and "call 911." Tobii, which is compatible with Bluetooth technology, will call for her.
"Truthfully, I was so amazed when I found out about the Tobii," she said. "It makes me feel good that I can personalize my messages to whomever. It is my lifeline."

ALS is a neurodegenerative disease that attacks the motor neurons. As the disease progresses, these neurons begin to degenerate and stop sending messages to muscles. Eventually, individuals diagnosed with the disease lose the ability to move their legs, arms and body.

According to the National Institute of Neurological Disorders and Stroke, 20,000 to 30,000 people are living with ALS in the United States. The average lifespan for a person with ALS is three to five years.

Because ALS patients lose strength and movement in their limbs, Tobii has a built-in eye tracker. Shearn can sit in front of the device - without moving any part of her body but her eyes - and still communicate effectively.

Jocelyn Odlum, a speech pathologist at the University of Miami, met Shearn at an ALS support group in West Palm Beach and then began seeing her at the clinic. After evaluating Shearn, she got her started on voice banking. Shearn has been recording her voice every day for the past two months.
"Carole is an inspiration," Odlum said. "She took this disease and is doing everything she possibly can to be prepared."

Odlum says that once individuals are diagnosed with ALS, they should see a speech pathologist immediately so they can be introduced to these devices and helped. "Unfortunately by the time people come to see me they have no voice," she said.

Shearn has recorded basic phrases such as "Hello. My name is Carole," and "How was work?" But, she also has recorded some of her other favorite phrases: "What's up buttercup?," "What's new, super glue?," and "You snooze. You lose."

When Shearn was initially diagnosed, she had no idea what ALS was. She also didn't know that the disease had no cure. "That was very hard to hear," she said.

"I had tears in my eyes of course and I asked how long I would have to live and my doctor said he didn't know, three to five years, so we left the office on that," she said.
Shearn's daughter, Jennifer Wagner, had been suspicious of early symptoms she had been noticing: slurred speech and choking spells, even when she wasn't eating. She researched her mother's symptoms and learned about ALS.

"It was very daunting and difficult to read," she said. "I had a pretty good idea of what the disease was and what it was going to entail, and I didn't want my mom to go through that."

Although Shearn can still drive and walk without any assistance, Wagner drives her mother from West Palm Beach to the university. She also started an open Facebook page called Carole's Crusade, where people can become more aware about the disease and follow her mother's progression.

"I know that I cannot cure the disease so my main goal is to bring attention to it," she said.

For Shearn, keeping a positive mindset has helped her cope with the disease, but she acknowledges she is not as hopeful and optimistic as she was eight months ago because she notices herself "getting a little worse."

"I was certain I was going to live past 90," she said. "I would still like to." But if she doesn't, Shearn says she feels she has done everything she has wanted to do - traveled to Rome, Alaska, Paris, England, Italy, Spain and the tip of Africa, been surrounded by good people, and had a successful 36-year teaching career.

"My life has always been about people so I don't crave a lot of outside influence," she said. "Our family is small, but we are tight. That has always been everything to me. I feel my life has been blessed."

Pupil response may help brain-damaged patients communicate

Pupil response may help brain-damaged patients communicate

Via: Los Angeles Times
http://www.latimes.com/news/science/la-sci-retina-20130806,0,4412651.story

August 5, 2013, 8:02 p.m.
 
A study suggests that, even if someone can't blink at will, their eyes can indicate a response to a question.
People with brain damage that has left them mute and motionless may be able to communicate with a system that measures the size of their pupils, a new study has found.

Individuals suffering from "locked-in syndrome" have lost motor control but remain aware and alert. The rare condition usually results when damage occurs to the brainstem, which controls motor function. Stroke, traumatic brain injury and amyotrophic lateral sclerosis (also known as Lou Gehrig's disease) can cause locked-in syndrome.

Many locked-in syndrome patients communicate with an alphabet chart, blinking to indicate their choices as a caretaker points to each letter. Others use devices that measure eye movement patterns representing "yes" or "no." Completely locked-in patients who aren't able to move their eyes at will may be able to use systems that translate brain activity into speech, although these often require surgical implantation and special training.

A new system called the EyeSeeCam measures changes in pupil size that happen involuntarily — even in people who lack motor control — and decodes them into yes or no responses, potentially offering an easier alternative for locked-in syndrome patients, including completely locked-in individuals.

In the 1960s, researchers discovered that pupil size can be used to measure mental effort: The bigger a person's pupils, the harder his or her brain is working. Neuroscientists used these findings to develop the EyeSeeCam, which takes advantage of how people's pupils dilate when they try to solve math problems.

Since this happens automatically, patients don't need to be trained to use the EyeSeeCam, said Wolfgang Einhauser, a neurophysicist at Philipp University of Marburg in Germany who helped develop the device. It's also relatively inexpensive, consisting of just a camera and laptop.

In a trial described Monday in the journal Current Biology, Einhauser and his colleagues asked patients 15 simple questions, such as "Are you 20 years old?" After each question, the computer presented the patient with yes or no options while showing a math problem onscreen.
Patients solved only the problem associated with their response, and the mental effort caused their pupils to dilate. An infrared camera mounted to a headpiece measured their pupil size over time and sent the information to a laptop. A software program immediately translated the measurements into responses based on when they peaked.

When the researchers tested the EyeSeeCam on six healthy individuals, it decoded their pupil sizes into accurate answers almost every time. The researchers saw similar results in three out of seven locked-in syndrome patients, almost all of whom could manage small head movements. With some slight adjustments, it correctly translated the pupil dilations of two additional patients more than 70% of the time.

"We found that quite remarkable," Einhauser said.

Only one out of four patients with more severe locked-in syndrome — marked by more widespread brain damage — finished the trial, and his answers were no more accurate than guessing.
The researchers also tested the EyeSeeCam on a minimally conscious patient with severely impaired cognitive ability. Although he couldn't answer the questions independently, he was able to solve math problems if the researchers pointed at them. The system translated these responses with more than 80% accuracy, suggesting that it could also serve as a diagnostic tool to assess a patient's state of consciousness, the researchers wrote.

Within the next two years, the researchers hope to finish fine-tuning the EyeSeeCam so that it works better for severe locked-in syndrome cases, Einhauser said. They also plan to make the device less cumbersome. It will eventually resemble a small webcam that can be hooked up to a laptop.

Although completely locked-in patients stand to benefit most from the EyeSeeCam, the trial participants still had control over their eye movements, said Niels Birbaumer, a neurophysicist at the University of Tuebingen in Germany who was not involved in the study. As a result, "we have no idea whether pupil size" accurately reflects yes or no responses, he said.

Mark Delargy, a physician at Ireland's National Rehabilitation Hospital, agreed. Although the study controlled for lighting changes and other environmental factors that can affect pupil size, internal variables, such as emotional state, are more difficult to control. Anxiety and pain can cause the pupils to dilate, for example.

But identifying these emotions in locked-in patients is tricky. "They won't tell you any new information," said Delargy, who was not part of the study. "You have to devise a question to enable them to tell you."

The EyeSeeCam's success in the minimally conscious participant has made the researchers confident that pupil dilation can serve as a means of communication, Einhauser said. Now that they've "provided the proof of principle," testing the system on completely locked-in patients is "definitely on the agenda," he said.

Even if pupil size does accurately reflect yes or no responses, the study tested only the EyeSeeCam, so it's undetermined whether it offers an advantage over existing systems, Birbaumer said.
Still, the device "has potential," Delargy said. "This is one of the greatest hopes for rehabilitation of locked-in patients and for the opportunity to give a voice to people who have lost it."
