Cyber Eyez M300 – smart glasses

Smartglasses or smart glasses are wearable computer glasses that provide additional information alongside to what the wearer sees (i.e. Wikipedia article).

Most of manufactures that develop smart glasses focus on including features such as clear pictures, videos, music, light weight, long battery life, light level adjustments, styles, and have compatibility to run on multiple devices with different operating systems. I am not a user of smart glasses, but I am always interested in accessibility that these glasses on the market can provide or what kinds of features are included to help persons with special needs. Visually impaired persons require additional features from smart glasses. I posted a blog about one smart glasses products, OrCam, in January, 2018. Cyber Eyez (Cyber Times) apps running on Vuzix M300 smart glasses is another accessibility option that may be suitable for persons who are visually impaired. Both smart glasses can recognize objects, personal items and people’s faces and read it back, but one of the differences between these two products is that Cyber Eyez can magnify up to 15X.
However, Cyber Eyez may require additional improvements such as a larger display screen for persons with very limited vision.

Cyber Eyez features include:

  • Real-time Magnification up to 15x.
  • Read to Text (OCR) for over 100 languages with or without internet connection. Take a picture and read it back.
  • Computer Vision based real-time bar code scanner with ability to find and read a bar code in less than one second.
  • Recognize over 16 billion objects with machine learning.
  • Identify over 1,500 colors with machine learning. It gives the shades of colors by using the percentage of the colors.
  • Sense moods on faces to know if they are happy, sad, angry, etc.
  • Support Skype
  • Alexa support
  • Flash light

Most users seem to find that smart glasses benefit them to be more independent in their daily activities. Unfortunately smart glasses are still priced high especially for the glasses with additional features (i.e. CyberEyez – above $2400 ).

Free Online Learning tools – Math

As you may have noticed, many students prefer to learn in digital learning environments today. Take for example, in learning math (mathematics), students may have difficulties to comprehend the relationship between a number and a graph on a piece of a paper. Calculators can be helpful for some students, but parents and teachers may still need more effective methods to help learners in solving math problems. Online tools and apps may be able to motivate students to tackle math problems and more closely match their learning style.  Here are some online examples that are available to use for free.

Geogebra  (URL:

It is an online drawing and graphing tool. You can type in an equation, and the geogebra tool draws its graph on screen. You can export the graph and review it later. In addition, if you draw a shape or line within the virtual graph paper, Geogebra will convert it into an equation. The tool also has a built-in calculator.

EksoGT and eksoZeroG / eksoVest

According to Ekso Bionics, each year as many as 500,000 individuals experience a spinal cord injury and 15 million others suffer a stroke.  So when I saw a trailer of the Avengers with Iron Man, I thought it would be exciting if a wearable device could help persons with disabilities gain their mobility and independence.

Ekso Bionics is developing wearable devices to help the recovery process within a clinical setting. EksoGT  is a robotic wearable exoskeleton, which is an FDA approved product for individuals with hemiplegia due to stroke. Over 200 clinical centers worldwide use EKsoGT for their patients during their rehabilitation treatments. Ekso Bionics clinical studies indicate that their EksoGT gait training rehabilitation for stroke victims improves their functional mobility and may improve walking without the device.  In addition, Ekso Bionics developed eksoZeroG and eksoVest, which help productivity for construction workers and reduce their fatigue in the work environment.

AVA – app for deaf or hard-of-hearing

Deaf or hard-of-hearing persons have challenges in communicating with others in their daily life. Especially in a group conversation settings such as meetings or social gatherings with friends and family, it is difficult for them to participate in conversations. If your closest friends, coworkers, and relatives are open to trying a solution for deaf or hard-of-hearing persons, an app called “AVA” will help to increase their involvement and encourage their interactions. Expanding and encouraging to create an environment to include deaf and hard-of-hearing persons in social, work, and school settings is essential.

Ava offers two plans. You can join Ava conversations for a free or a paid plan. The free plan allows 1 or more friends to use for up to 5 hours per month. The other plan is real-time captioning with 1 or more friends, with no monthly limit for $29.99/mo. Ava can understand and transcribe 12 spoken languages: English, French, Dutch, Spanish, Portuguese, Russian, Arabic, Thai, Chinese, German, Italian, and Norwegian.

To use Ava, you need to install the app on your smartphone (i.e. iPhone/Android) and will need to create an account and allow access to your camera on your phone. You can use the app on one-on-one conversation on your phone or you can use it in a group setting. In a group setting, it is best to ask others to install on their smartphones. Within the app, use the option of sending “invite” from your contacts. Then a written text will be sent to the person with instructions of how to install AVA app. Or if you are in the same room and would like to speed up to add people, you can use the QR code button on top-right and share the QR code to each person. Next time you can just tap “green Connect” to include the person in the conversation.

Some users reported that the accuracy is not 100% and depends on how you use the app. For example, the distance of about a foot from the speaker is about 85-95% accuracy. The noise and the accent of the speaker and rapid speech may reduce this accuracy rate. Use of wired microphone may increase the accuracy. In addition, captions are normally displayed between 1-3 seconds after words are spoken; however, if you have a slow internet connection, you may experience a delay in captioning.

The following are a YouTube video of this app, AVA, and its installation/configuration instructions.

OrCam MyEye 2.0

OrCam MyEye 2.0 device is a smart camera about the size of a finger and a microphone attached to a pair of glasses. The device can read printed materials such as books menu, labels, and signs. When the user points a finger at text, the device activates the text-recognition technology and reads aloud what’s in front of the camera. In addition, OrCam can read digital text on computers, smartphones and has money, color, and face recognition features. MyEye 2 can store up to 100 faces such as your friends, family and co-workers and can also store up to 150 of items of your choice.

OrCam MyEye 2.0 – 2018 ((YouTube video by OrCam, December 2017)

I posted a blog about OrCam in 2016 as a prototype among Smart glasses, but as of last year, 2017, it has reported approximately 5,000 users around the world. According to feedback from some users, the intonation or emphasis of the voice from the OrCam is awkward and has very little rhythm so it may not be comfortable for listening over a long period of time. However, others state that the device helps them be more independent in daily tasks and improves family interactions such as reading a bedtime story for their children. One mother used OrCam to read the page and then said it aloud to her children (2017, The Guardian). Unfortunately the prices are still too high (i.e. $3500 – $4500) for many people. Here is more information about OrCam MyEye 2.0.

Grit Freedom Chair – The all-terrain wheelchair

Typical standard manual wheelchairs have large rear wheels with an extended rim called the hand-rims allowing the user to self-propel. However, it is difficult to push on unpaved roads or grassy fields.

MIT R&D and their students started the initial concept for the GRIT Freedom chair in 2008. They have tested their designs in toughest conditions in East Africa, rural Nepal, and Haiti. GRIT Freedom chair, all-terrain wheelchair have made possible for wheelchair users to go off road like a mountain bike allowing to use on grass, sand, and rough terrain.

GRIT wheelchair (All-terrain wheelchair) uses lever drives which make it easier to push the chair forward than standard wheelchairs and stop without grabbing slippery hand-rims. The following are the pictures of a standard wheelchair and the GRIT Freedom chair. This picture of this GRIT Freedom chair shows two hand levers but these are detachable depending upon the environment and the type of roads you travel. It is portable and can be fit in the trunk. The heaviest part to lift into a car weighs 25 pounds. In addition, the GRIT Freedom Chair uses an off-the-shelf bike drive so most local bike shops can repair.

Liftware – Self-Stabilizing Eating Utensils

Persons who have difficulties with using regular utensils such as a fork and spoon because of their health conditions related to Parkinson disease, cerebral palsy, spinal cord injury, Huntington’s disease, or post-stroke deficits, may benefit from using Liftware utensils. Liftware offers devices which can help a person hold utensils and eat more easily. They offer two different products for meeting the individual’s conditions and needs.

Liftware Level is a device which is suitable for persons with limited hand and arm mobility. By using Liftware level, they can keep their eating utensil level at the angle needed in spite of how their hand or arm turns, bends, or moves.

YouTube video:  Introducing Liftware Level posted by Liftware

Liftware steady, which is an electronic stabilizing handle with a utensil such as a spoon, fork, and spork. The device works great for persons who have tremor due to Parkinson’s disease to help them eat more easily.

YouTube video: Introducing Liftware Steady posted by Liftware

It stated that the handle of the device has a small onboard computer that directs and distinguishes unwanted tremor movement vs. the intended movement of the hand. The computer directs two motors in the handle to move the utensil attachment in the opposite direction of any detected tremor so that the user can control the utensil while eating. As a result, Liftware products seem to offer more stability and controls compared to low-tech weighted utensils so that it makes mealtime easier for persons who suffer from tremors and shakes in their hands or have trouble stabilizing silverware. However, the price (approx. $195) is expensive so hopefully those that need this device can get their insurance company to help cover the cost.

For example, the following information is taken from the Parkinson’s Foundation ( The Parkinson’s Foundation is part of the Liftware donation program for people who cannot otherwise afford the device. If you think you could benefit from the device, call the Parkinson’s Foundation Helpline at 1-800-4PD-INFO (473-4636) to talk to one of our PD Information Specialists about whether the device is right for you.

Persons with vision loss face challenging situations daily, especially when they need to travel, do certain tasks by following instructions or getting information for themselves. They may find this product and service called Aira to be very helpful.  Aira consists of smart glasses with a camera which is connected to the user’s smartphone. Then a remote, trained vision interpreter assists persons with visual impairments.  A vision interpreter can get instant feedback from the camera and describe whatever is in front of the user or provide detailed information such as instruction manuals for the user. However, Aira is not designed to make decisions. For example, when a blind person reaches at a traffic intersection, Aira can provide the user with the information on if the traffic light is green and no cars are coming, but it is up for the user to make a decision of when to cross the road.

We often find it is difficult to offer additional support on how to use assistive technology devices after providing a technology solution.  This is one technology product combined with service developed for persons with special needs. They offer subscription services with a 3-month intro price starting from $89 for 200 min and higher. More information and pricing can be found at:
