Man Spends 30 Years Helping Disabled Gamers

Using our hands to manipulate game controllers is something most of us take for granted. However for quadriplegics, whose arms and legs are completely paralyzed, gaming becomes a nearly impossible task. One man has spent the last 30 years of his life trying to help quadriplegics once again “pick up” the controller and enjoy a few rounds of their favorite video games.

Retired aerospace engineer [Ken Yankelevitz] has been using his skills to create game controllers that can be easily used by disabled gamers, offering them for sale at cost. Starting with Atari joysticks in 1981, he has been perfecting his craft over the years, creating some 800 mouth-operated game controllers. As the systems and their controllers became more complex, so did [Ken’s] designs. His new Xbox and Playstation controllers use all manner of components, including sip-puff tubes and lip-activated buttons in order to allow users to access every single controller function.

Even as he approaches his 70th birthday, he is busy making controllers, though at a slower pace than he has in the past. He has said that he will continue making them for as long as he can, but at some point he will have to close up shop. This has disabled gamers worried that they may no longer have someone to turn to for custom controllers, though we hope someone steps in to fill the gap whenever that day comes.

Be sure to check out his site to take a look at his designs, what he has done for the disabled community is amazing.

Giving “sight” To The Visually Impaired With Kinect

March 16, 2011 by 27 Comments

NAVI

We have seen Kinect used in a variety of clever ways over the last few months, but some students at the [University of Konstanz] have taken Kinect hacking to a whole new level of usefulness. Rather than use it to control lightning or to kick around some boxes using Garry’s Mod, they are using it to develop Navigational Aids for the Visually Impaired, or NAVI for short.

A helmet-mounted Kinect sensor is placed on the subject’s head and connected to a laptop, which is stored in the user’s backpack. The Kinect is interfaced using custom software that utilizes depth information to generate a virtual map of the environment. The computer sends information to an Arduino board, which then relays those signals to one of three waist-belt mounted LilyPad Arduinos. The LilyPads control three motors, which vibrate in order to alert the user to obstacles. The group even added voice notifications via specialized markers, allowing them to prompt the user to the presence of doors and other specific items of note.

It really is a great use of the Kinect sensor, we can’t wait to see more projects like this in the future.

Stick around to see a quick video of NAVI in use.

Xbox 360 Controller Mod For A Friend In Need

March 3, 2011 by 30 Comments

[Adrian] has a friend that, due to an accident, can no longer play Xbox games in the standard fashion. His friend is unfortunately unable to hold the game pad properly, and no longer has the manual dexterity to reach the shoulder buttons and triggers on the top side of his Xbox 360 controller. Being the good guy that he is, he set out to see what he could do in order to bring the joy of playing Xbox back into his friend’s life.

Inspired by the many different gaming mods he has seen [Ben Heck] construct, he pulled apart an Xbox 360 wireless controller and began to investigate how the four top buttons were activated. In no time, he had four large buttons wired to the PCB where the triggers and shoulder buttons once connected.

[Adrian] mentions that his modification isn’t quite complete, as he is going to mount the buttons into a board which can easily be laid on his friend’s lap or a table. The only thing we are left wondering is whether or not he was able to replicate the analog functionality of the triggers, or if they are treated as simple on/off switches. Either way, we are sure his friend will be thrilled!

Talking Joystick Mouse

February 10, 2011 by 8 Comments

Instructibles user [Shadowwynd] shows us a great way to build a joystick/mouse device for people with special accessibility needs. When faced with a case that involved a man with very limited mobility as well as a limited budget, [shadowwynd] set out to find a cost effective solution to computer navigation. They found that his client could use a commercial joystick mouse, but the cost was quite high at over $400. So instead of just purchasing that, they bought a USB game pad and built their own version. They managed to reduce the cost to roughly $45.  While extending the buttons and joystick from a gamepad might not be groundbreaking, we feel that this project is the epitome of hacking. Great job [Shadowwynd] keep up the good work.

Door Opening Help

November 27, 2009 by 21 Comments

For those who are seeking prosthetic limbs, or just require a little bit of robotic gripper help, the choices are very few and very costly. A newcomer to the area is hoping to change the costly part with their door opening arm. Costing only $2,000 to build, it is quite cheap compared to the other offerings. This arm can grip, twist, and swing its arm at the same time using a single motor thanks to a slip clutch.

PSP SNES Controller Mod

October 29, 2008 by 27 Comments

[foo] sent in this amazingly well done mod to add an SNES controller to a PSP. He was contacted with a request to mod a PSP for someone who had limited use of one hand. The PSP controls were too difficult for her, but miraculously, she could play an SNES controller well. The quality of the mod is very nice. [foo] has added a port on the back that the controller plugs into. Other than the port on the back, the PSP looks completely stock and functions fine. When plugged in, the cable and plug act as a stand for the PSP too. Check out the video after the break for more.
