- Braille Buddies
Teaching Braille to blind and low vision children at a young age increases their chances of earning advanced degrees and finding employment in the future. Our work seeks to provide a novel way of delivering Braille instruction to these children. We built a fun and educational game, called BrailleBuddies, for blind and low-vision users, integrating Braille reading and writing exercises into the backdrop of the game. We developed BrailleBuddies to run on mobile devices, taking advantage of the portability and pervasive use of these devices within our society to make the game readily accessible to all.

- Color Namer
We have a program which allows the user to determine the color of an object, by pointing the phone's camera at it and tapping the screen. We try to select one color from the eleven common color names of English. We are trying different algorithms to choose a color which best describes what the camera sees, including a classification tree and a statistical model. These models will be trained using data collected from the phone's own camera. Code Repository

- Input Types Demo
Demo that shows different types of accessible input screens, including speech input (uses voice recognition to input letters of the alphabet), tap and hold input (non-visual, touch-based navigation through the alphabet to the desired letter), and soft keypads (touch and drag around screen to hear letters, double tap to select).

- LocalEyes
This project uses text to speech software and the Android location services to determine the users current location and speak the approximate address. It is currently being expanded to provide other navigational information, such as walking directions, and present information through a non audio interface such as which businesses are ahead and behind the user.

- MobileOCR
Mobile OCR uses a powerful optical character recognition (OCR) engine to provide low vision and blind individuals with a way to read printed text on the go. The user is completely guided through tactile and audio feedback. Text is output using a text to speech engine in conjunction with a screen reader. The screen reader is controlled by simple gestures. Mobile OCR, in addition to being accessible, is completely open source and provides a great framework to build off of.

- VBraille
We have developed a way to haptically present Braille characters on a mobile phone touch screen with the phone's vibrator, called V-Braille. Studies so far have shown that with minimal training, V-Braille can be used to read individual characters and sentences. There is a potential for using a standard mobile phone with deaf-blind users who rely solely on tactual perception to receive information. We are also currently testing this with our Braille games listed above, with blind and low-vision children in elementary and middle school. Project Page

- VBReader
V-B-Reader allows both blind children and their parents to practice reading Braille letters using vibration to represent raised dots. Taking a digital flashcards approach, the letters are presented one at a time in random order, and the player drags his finger around the mobile device's touchscreen to feel which dots are vibrating. By equating the location of the vibrations to the dots of a standard Braille cell, the player tries to figure out which letter is being displayed. Pressing the Enter button on the mobile device speaks the letter name before advancing to the next letter.

- VBWriter
V-B-Writer allows both blind children and their parents to practice writing Braille letters by double tapping on the regions where the letter's raised dots should be placed. One at a time, a letter is randomly selected and the name of the letter is spoken by the application. The touchscreen containing only empty dot outlines (meaning no dots are raised) is presented and it is up to the player to double tap in the regions where the dots of the current letter should be raised. Double tapping on an empty location will cause a dot to appear and the device to vibrate when that dot is touched. Double tapping on a location where a dot currently exists will cause the dot to be removed. Pressing the Enter button on the mobile device submits the player's input and the application responds via text-to-speech to confirm whether the input was correct before selecting a new letter to present. Additionally, if the input matches a different letter rather than the one expected, the application will say so.
