3D printing for disabled

Since I posted a blog about 3D printing in 2014, technology using 3D printing has continued to benefit disabled persons in increasing their independence and daily activities. One of the benefits of 3D printing for people with disabilities is that the tools or parts can be quickly produced and customized for individual needs. Some designers find that it is less expensive than purchasing assistive technology devices.

Don Fredette, an adaptive equipment specialist, uses a 3D printer to make items such as customized wheelchair joysticks, control knobs, and cup holders at the Boston Home, a residence for Care of adults with advanced neurological diseases. In addition, he has also made the following 3D printed items.

  • Cradles for voice-controlled television remotes
  • Chin switches for calling aids
  • Holders for communication devices like phones and tablets
  • Cell phones

Another example of 3D printer beneficiary is Christopher Hills of Australia. This nineteen-year-old owns his business called Switched-On Video Editing. He uses Final Cut Pro software and edits films with customized 3D printed switches that he controls by moving his head.

In addition, 3D printing is helping to create more advanced products. Scientists, engineers, and physicians have been developing and building 3D-printable prosthetics and the next generation of bionic limbs that can be fully customized.

Open Bionics made a custom fit a 3D printed robotic arm with hand for Daniel, who was born without a right arm.  They scanned his arm using a 3D sensor, created a 3D mesh of it, and printed a custom-fitted socket and robotic hand. The robotic prosthetics arm gave Daniel the ability to write, pick up things, and shake hands – abilities to do these tasks which most of us take for granted.

The MIT Media Lab’s Bio mechatronics group led by Hugh Herr has been developing wearable robotic systems that serve to augment and enhance human physical capability. Hugh Herr himself lost both legs to frostbite when he was younger. Here is a YouTube video where Hugh Herr talks about the next generation of bionic limbs, and robotic prosthetics.

A security monitoring system without monthly fees

You may be considering about a Home automation system with many features or you may just want to have an alarm or notification system for certain situations.  For example, you may be looking for a system that can send you an alert (i.e. text message) by using a door sensor or a camera to monitor an older adult or a child at home.  However, you may not want any lease commitment and pay a monthly service fee.  Then you might consider using a Do-it-yourself security system.

There are many monitory systems (i.e. security camera) on the market. Most companies charge a monthly or yearly service fee, but some equipment can be bought up front and require no fee or aftermarket contract if you install and configure the notification system by yourself. The consumers’ reviews vary depending upon their experiences. So instead of selecting one because a new product is on the market or it is reasonably priced compared to other products, it is recommended that you research other users’ experiences and compare the features before you purchase a system. Security Resources for Home & Online (www.asecurelife.com) provides you with the product pros and cons information. Amazon (www.amazon.com), where many manufactures sell their products, post users’ experiences. These are helpful resources because you get the product information as well as users’ experiences and opinions after using the product for a while.

One should consider the following: The quality of any security cameras depends upon the light, the reflections of the windows, the resolution of the cameras, the availability of both night and day vision, video and audio availability, and how you can angle the camera or how wide of an area you can capture. Some users have experienced not being able to capture because of the limitations of the camera angle, a poor quality image, or poor audio. False alarms are something you want to be aware of. Some users are getting too many false alarms because of their house pets or not getting any alarm because of their wireless network unavailability. One user noted that the delay of the notification resulted in not being able to act upon immediately. If you need to store the information, you can store the information in your local drive (i.e. SD card/computer drive, etc.) or in the cloud with fee after a 30-day trial on some systems. A few users stated that the customer/technical service is important because you may experience problems during the installations or configurations. Other challenges are the product may only work with the apps or software from the manufacture which may not be compatible with other apps for iOS/Android. In fact, Apple stopped posting some products under their Home Automation kit list. A few reported problems and concerns about network security issues.

The following links include a few no-fee security system reviews, but most companies charge for additional features such as saving the video streaming in the cloud.

The following are a few security systems with no fees or fees on additional features (i.e. recording).

How to turn your old phone to a security camera

If you are planning to expand the home automation (i.e. door/window sensors, lights, and temperature controls), it is recommended that you check with the total cost as well as the compatibility such as you can pair with the existing system. Some products may already have the additional built-in features you need.

Object Identifier apps

If you are looking for an object identifier app for someone with low vision, blind, or simply teaching someone what each object is, you may want to use and compare the following object identifier apps. Surprisingly I have found that most of the following apps work well, although sometimes objects were identified as wrong or some apps fail to identify it.

Object identifier apps recognize objects, colors, and text by using visual mobile search technology after taking pictures of the object on the smartphones (iPhone/Android) and tell you what it is.  Some apps can share identification via text, email, or social media and are accessible with VoiceOver. If you have an older smartphone, you may not be able to download and install some apps. However, Taptapsee app can be installed on an older device such as iPhone with 3G OS.  Object identifier apps have been updated in the last few years. For example, CamFind app now works with not only smartphones, but also with the Google glass wearable device. Here are a few URL links to start your search.

Sesame touch-free smartphone

You might have heard about the Sesame touch-free phone in 2014.  The Sesame Phone is powered by both Voice-Control and Computer-Vision technologies. The technology was made for people who have limited or no use of their hands so that they can operate a cellphone with head movements. Persons with Spinal Cord Injuries (SCI), multiple sclerosis (MS), cerebral palsy (CP), and arthritis can benefit from a touch-free phone.


Sesame touch-free phone was designed by co-founders Giora Livne, a quadriplegic veteran and electrical engineer, and computer vision expert Ben Dov.  They have won various awards: Verizon Powerful Answers (2014), Nominet Trust 100 (2014), and the Michael Bloomberg’s Genesis Generation Challenge awards (2015).

In Israel, the company is offering its devices for free to disabled according to the recent news in December 2015.  So I have started looking for if any companies are offering the sesame phone in US.

The Sesame phone is a specially configured Nexus 5 smartphone, and the phone can be purchased online. It sells for about $700 (US) plus shipping through the Indiegogo online site. They’re offering a full money-back guarantee, including shipping both ways, if you are unhappy with your device. However, it does not seem there are any US-based stores you can walk into.  I tried to contact via e-mail through both the Sesame enable and Indegogo websites to find out their current updates. Unfortunately I have not received any replies from them at this time for this blog.  Instead I have only received a request for donation; if I get any updates, I will post additional information.

In the meantime, here is the Sesame enable website:

How the sesame touch-free smartphone works

Additional information from Sesame Enable (2/1/2016):

Sesame Enable informed that it is available over SIM Card only ( i.e.Verizon, Sprint, T-Mobile is not an option yet, and AT&T is plausible). You need consult your carrier by a bring your own phone plan. For now, Sesame Phone is available exclusively on an Lg/Google phone Nexus 5.

Senior Services – Nursing Homes

Technology is rapidly changing, but the evaluations of ‘Services’ are important areas for the successful delivery model. Take for example, nursing homes or long-term care environments in the Baltimore area were reported for negligence by a local news channel. This is actually quite common as many nursing homes in US were cited for repeated violations of health, safety, and quality care. However, they are still permitted to operate and take in new residents at their facilities (Coalition for Quality Care). Often many facilities fail to create individual care plans for residents or do not permit residents to participate in their own planning.

One article reported 1.5 million nursing facilities in US, and there is a need for interventions that are tied to standardized measurement and quality improvement programs. For example, one of their research studies was conducted among 164 residents at three not-for-profit nursing homes in Pittsburgh, PA area.  The items are organized into 12 domains: comfort, security, food enjoyment, privacy, meaningful activities, religious practices, relationships, functional competence, dignity, individuality, autonomy, and spiritual well-being.

The findings from the research suggest that effective interventions need to be personalized to the individual resident. Facility-wide improvements should not be neglected. However, the best improvements are ones that assist staff to recognize and act on individual residents’ preferences.

A chart referenced by the QOL study.

Note: The QOL (Quality of life) care plan related to security focuses on relationships with staff. Each category description: click here.

What about overseas? An article in the New Ergonomics Perspective reported that the available resources for taking care of elderly at home are gradually diminishing in Taiwan. As a result, it presents a considerable change to meet the needs of Taiwan’s ageing society and review the quality of services at nursing homes. In the article, the researchers addressed the importance of identifying resident’s feeling and preferences into the service design specifications.

Nagamachi, a Japanese professor, founded the Kansei Engineering (KE) method that translates customer’s feeling into a design specification and minimizes the subjective interpretation of emotion.

A study using the Kansei Engineering method and Kano model was conducted among 42 elderly from four nursing homes from November 2013 and March 2014. The researchers interviewed each resident for about 30-50 minutes. They residents expected the employees’ dependability and competency. However, the result shows that the three service attributes with the highest requirements are: 1) medical instrument & physical facilities are visually appealing; 2) feel safe and feel at home; 3) quick medical treatment response when patient needs it. On the other hand, the residents do not expect their activities are well scheduled.

The study conducted in US showed their residents’ desire toward security is high. In this case, the security focuses on their relationship with the staff and how well their needs and daily personal cares are provided for. On the other hand, the study conducted in Taiwan concluded that the needs of appealing medical instruments & pristine physical facilities ranked highest among the residents. Depending on the locations and the facilities the residents’ priorities can vary based upon their preferences and needs in their environments. However, both studies state that the elderly should be involved in their daily life planning and how the nursing homes can help them to achieve their desires. Evaluating the service quality of nursing homes or long-term facilities should be done periodically. Technology helps the independence of persons with disabilities or elderly, but its careful monitoring individual’s needs toward the desired outcomes is essential.

AutoMath Photo app for Android

AutoMath Photo app for Android has been downloadable from Google Play for over a year so you might have already tried the app by now. Unfortunately, it still cannot always recognize your handwritten equations, as AutoMath answers math questions by taking a photo of equations.

AutoMath app screenshot

AutoMath screenshots (from left to right: Photo, Edit equation, and Graph modes)

The features include:

Step by step answers
No internet required
Can solve simple to advanced math questions
250+ Mathematical Functions

AutoMath Photo Calculator Currently supports:

Addition, Subtraction, Multiplication, Fractions, Division, Inequalities, Powers, Polynomials, Linear Equations, Square Roots, Trigonometry, Algebra, Simplification, and Basic Algorithms

Not supported: Any other math problems such as calculus, systems of equations, complex math, graphing, table of values, and any functions not specifically mentioned.

However, Pocket Math Tutor is available if you sign up with fee: 24/7 Answers & Steps to all your math problems (including math word problems). It says your first question is free though.

It looks like how you take the picture of the printed equation matters the accuracy. For example, while testing, I have found out that if there is an extra line above of the equation, it takes as a fraction and ended up 0 divided by the equation. If you can take a picture by eliminating white spaces and focusing to the equation itself, Automath returns an accurate answer. The Edit mode option, which allows you to modify the equation or enter the equation instead of taking a picture, is helpful.

Automath provides step-by-step guidance to get the answer so you can understand how to solve the problem or graph it. The app may help you to recheck your work or learn to solve problems on the supported Math functions. Just be aware that a step-by-step solution may not be available depending upon the equation. Some users stated that taking a picture of each equation or understanding how to use the app is not easy.

Honda Walking Assist Device

Honda Motor Co., Ltd has been working on the development of the Walking Assist Device since 1999. As with the ASIMO robot, Honda’s humanoid robot, the Walking Assist Device uses new control technologies. The Honda Walking Assist Device has been tested at 50 hospitals in Japan as well as a clinical research study which has been conducted at the Rehabilitation Institute of Chicago (RIC) since 2013. Honda has received positive feedback from users, physical therapists, medical professionals, and researchers, all of which acknowledge the effectiveness of the device for rehabilitation.

Now this coming November, the Honda will start leasing the Walking Assist Device (approx. 450 units/1st year) to Japanese hospitals and rehabilitation facilities. The device can help training of walking and guiding to achieve effective walking for persons with reduced walking ability due to injury, illness or other causes (i.e. stroke). The key features of the Walking Assist Device are compact, lightweight, and easy to put it on because it is worn outside of clothing. The Walking Assist Device influences the user to achieve motions such as bending and extending both legs. It also helps user’s leg motions which enable smooth shifting of weight from heel to sole and sole to toe. One article in the Honda Website described as follows: “the control computer activates motors based on information obtained from hip angle sensors while walking to improve the symmetry of the timing of each leg lifting from the ground and extending forward and backward, and to promote a longer stride for easier walking.”

Naida CI Q30 and Q90

The Global Elderly and Disabled Assistive Technology market will grow at a Compound Annual Growth Rate of 5.59 percent during the period 2014 to 2019 according to an article (PRNewswire).

We may see variety of products with simple or complex designs among hearing devices, mobility and ambulatory devices (i.e. Wheelchairs, scooters, and walkers), vision and reading aids, and Ergonomic Furniture and Bathroom Safety Equipment.

For example, Advanced Bionics(AB), a part of the Sonova Group, will introduce FDA approval of enhanced Naida CI Q30 and Q90 sound processors in Canada and US sometime this year. AB is known as a global leader of cochlear implant technology. Some advanced features in Q Series include new microphone technology for focusing on speech and can block prominent sounds, such as wind and echoes, to enhance hearing in challenging settings.

Be My Eyes – helping blind see

iOS devices (iPhone/iPad) are very popular among the visually impaired mobile device users. For example, most of them use VoiceOver, which is a gesture-based screen reader, and comes on IOS devices. Voice commands let the user schedule meetings, make phone calls, and look up the nearest stores or restaurants.

Be My Eyes app may be also helpful to have on their iOS devices. If blind persons are living alone or in new environments, they may need to identify the detailed descriptions of the pictures or objects. For example, they may want to know the expiration date on a food label, a picture description or identify something in their new surroundings, but no one is around to help them, this app could help them. Be My Eyes is an app that visually impaired persons can connect with volunteer helpers from the world via live video chat.

Be My Eyes – helping blind see

After you install this app, you sign up as either a person needing help or as a volunteer person, who can help blind or a visually impaired person. If you speak more than one language, you can help people around the world.  When the CBS news talked about this app in February 2015, the volunteer number was about 114k. Now the number of volunteers increased more than double in August 2015 (289k).

Technology solutions for the visually impaired are not all available, and unfortunately, when it comes to funding, iOS devices are not easy for those with low-income to acquire. However, if you are an iOS user, you can be one of remote volunteer helpers by installing “Be My Eyes” app in new ways to help the visually impaired.   Here is the Be My Eyes app link to download.
