Linespace Tactile Interface for the Blind with 3D Printing Extruder

Linespace is an ingenious device that uses a 3d printing extruder to produce a large tactile interface for the blind. I love this project! This could be extremely useful for the blind people!

Project description:
Linespace is a tactile display system for blind users. The foundation of our system is a large 140x100cm display area, on which the system creates raised tactile lines with the help of a 3D printer. The foot switch allows users to enter text and issue commands by talking to the computer.

We use Linespace to give blind users access to the type of software packages that normally only sighted people can access, namely the type of software that helps them to make sense of complex data. So far, we have created a simple homefinder program, a spreadsheet program that can read and write Microsoft Excel, two simple games, and a simple programming environment.

One might say that Linespace is an interactive "visualization" system for the blind. The key to achieving this is Linespace large display as it allows displaying a lot of contents at once, where smaller display systems need to update screen contents. The use of lines (instead of the more common Braille dots) helps create visualizations.

The vision behind Linespace is to help blind users interact with and make sense of complex spatial data. It thereby intends to pick up the vision behind of Vannevar Bush's memex, Engelbart Online system, and Xerox PARC's personal computer, by investigating how we can recreate this type of interaction for blind users--how to use computers to help people think better.

In the video you see a user using this system to find homes in Berlin:

Library Lyna has 3d printable educational models to help blind students learn


Library Lyna is a repository collection of high quality educational 3D models to help teaching of the blind and visually impaired.
Great project!







Here is a Library Lyna homepage with MANY models which can be 3d printed and used in classroom:

Here is the image of the site with geometric shapes with Braille titles:

































If you want help someone who needs Braille signs, here is text-to-Braille 3d model generator:

FingerReader is a 3d printable wearable device for visually impaired




The FingerReader is a wearable device that assists in reading printed text. It has a 3d printable housing and it is developed by MIT Media Lab, Fluid Interfaces Group.
It is a tool both for visually impaired people that require help with accessing printed text, as well as an aid for language translation.
Wearers scan a text line with their finger and receive an audio feedback of the words and a haptic feedback of the layout: start and end of line, new line, and other cues. 
The FingerReader algorithm knows to detect and give feedback when the user veers away from the baseline of the text, and helps them maintain a straight scanning motion within the line.

Voxel 3d printed mobility assistance cane for the visually impaired




Another great example of using 3d printing for prototyping and developing new technologies for the disabled. I couldn't find more information on it except video description. It would be great if the creators would open source it.

From video description:
A smart white cane that helps the visually impaired keep active and independent.
Voxel gives anyone mobility assistance by integrating a traditional white cane, with new technologies.

An estimated 285 million people worldwide are visually impaired, with 39 million of those blind and 246 having low vision. The smart white cane, combines GPS technology and long distance measuring sensors, allowing the blind or visually impaired person to navigate public spaces with ease.
The user's smart phone's GPS, provides directional guidance. Turn by turn vibrational feedback is received through the handle, which allows the user to pocket their smart phone and have a hand free.
Feedback on obstacles is provided through LED lights located at the base of the cane. This helps those with low vision or other vision impairments such as macular degeneration, to become more aware of their surroundings and getting used to using a cane.
Using 3D printing, and the open source digital community, repairs are minimised and personalisation of the cane is only a limit of the current 3D printing materials.
The user is able to navigate the smart phone application through the use of accessibility, allowing them to order new or replacement parts.
Voxel gives anyone who is visually impaired the option to use an electronic mobility aid.

Here are two projects that can also hep visually impaired and blind:

Text2Braille website generates 3d printable Braille sign from text

Great idea! Web page that takes text input and generates 3d printable vertically standing braille signage file in Braille for the blind.
After short processing you will be able to download STL or X3D file for your printer.
There are few options and interface is in German but it is simple and Google translate can help.
I get a strange error when I load it but after refresh it works just fine.

Point of action: go find your local blind association or blind person and print them something they need

VIA (Visual Impairment Aid)

Wow! What an amazing project! Kudos Mr. Mizchief100!



From project page:

This project was my take on a DIY visual impairment aid that uses haptic and sound feedback. Basically it uses a distance sensor to measure how far objects are from it and then it beeps/vibrates accordingly (far away is slow vibrate/long beep delay and close up is fast vibrate/quick beeps). The difference between this project and others is this project uses one distance sensor (as opposed to many) to make feedback more specific and simpler to interpret, use of both haptic and sound feedback, the mounting of the device under the arm and not attached to the hand (keeps it free to feel where you're going and use for daily tasks), and a few simple control buttons on the case (I also put the word for each button in braille next to them). What I really like about the design is how compact and sturdy it is. I wore it around for a few hours to get used to it and found it didn't hinder too many of my daily activities (I found it fit in sleeves too!).
