Welcome to Blindfold Racer Championship, where 50 states and over 12,000 people play the game, win lovely prizes, have lots of fun with each other, race faster, higher and stronger.

There will be lots of categories to compete in – not just the highest score. And if you’ve never played Blindfold Racer before, it’s a game where you drive with your ears, not your eyes, and you don’t need to be a gamer to earn high scores.

Winners in each category will get recognized on blogs, podcasts, Facebook, twitter, newspapers, television and more. The Championship countdown starts on September 30 to Finals on October 14th.

We will announce details later this week, but here’s how you can get involved earlier: If you’ve played Blindfold Racer before, and you live in a major city, please contact me. We especially need to find people from Boston, New York City, San Francisco and Washington, D.C.

Blindfold Racer Championship is being sponsored by Blindfold Games and Project Starfish.  Registration is coming soon.  Tell your friends!


Blindfold Games: Why they seem so real

One of the challenges of building a game that you play against a computer opponent is to make it feel like you are playing against real people. I’ve talked about this in prior blogs, and Blindfold Pool, Blindfold Bowling and Blindfold Spin and Solve accomplish this by varying the skill of your computer opponent.

Another method is to give the appearance that the opponent is thinking about his move, and sometimes talk about his move. For example, in pool, after you take your shot and it becomes the computer’s turn, your opponent pauses he thinks about his move. Sometimes you hear him chalking his pool cue, or walk around the table to consider different shots, or make comments to himself, such as “Hmm, that looks like a good shot” or “I think I can do it”.

To avoid repeating the same phrases over and over again, we build a set of sentence fragments that can be mixed together to produce a unique sentence.   Consider, the sentence “That looks like a good shot” might be broken into 3 fragments: “that” and “looks like” and “a good shot”. Then we come up with five or six similar phrases to each fragment. For example, you could substitute the phrase “a safe shot” or “do-able” or “an easy shot” or “not so hard” or “a winner” for “a good shot”. So if there are 5 alternatives for each of the 3 fragments, that results in 5 times 5 times 5 combinations or a total of 125 possible sentences. Most games have at least 1000 combinations to keep the opponent sounding unique.

A second method is to make the competitor’s voice sound different. In Bingo, the best part of the game is when you make a bingo, and you can yell out BINGO. Blindfold Bingo lets you record yourself yelling BINGO, and then share that with everyone else.

When you play Bingo, and your opponent wins, she announces her BINGO in someone’s voice. The game does this by randomly selecting one of hundreds of BINGO recordings that other people shared.

As the Blindfold Games community grows, we’ll be adding more and more features to the games so people can share their voice recordings to make everyone’s game experience even more realistic.

Blindfold Games and RS Games

About 4 months ago, one of the great testers from down under – Australia – suggested that I contact other developers of Windows-based accessible games, and work with them so their games can be played on the iPhone and iPad.

I contacted several: some were excited, some were rude and dismissive.  I struck up a good conversation with the engineers at RS Games, and we talked for several weeks about customer expectations and experience, how our business models differed, and how we would approach the project.  Once we reached a verbal agreement, they sent me the programming code for their web client, and I proceeded to re-write it, so it would work on iOS.

For those of you who don’t know about RS Games, they’ve created about 19 multi-player games, including Monopoly, Uno, Yahtzee and Farkle.  Their games run on a game server, so people all over the world connect to the RS game server using the RS game client on Windows or the Mac, and play with each other.  They have been building games for over 5 years, so their games are quite popular and impressive.

Our joint project would let people participate in these online multiplayer games directly from their iPhone or iPad.

Most of the technical conversion was straight forward; the challenge was coming with how the game should behave if you didn’t have a keyboard.  RS Games are designed for rapid audio play with a keyboard.  On both Windows and the Mac, you use the keyboard to control the game, including the arrow keys and the function keys.  Without a keyboard, the game just wasn’t playable.

We came up with sensible iPhone gestures, based on the pattern that I’ve set out with the Blindfold Games.  For example, instead of using the arrow keys to cycle through a list of options (such as which game you want to play), you swipe up and down.

Once that was done, I mentioned the game to several testers, and they strongly felt that the game needed to use the keyboard as well.  Since many visually impaired people use an braille display, the game needed to work the same way on the iPhone with a braille display as it works on Windows and the Mac, with a braille display.

Most of that was easy; we had to make a few changes, since the F1 to F9 keys have other meanings when connected to an iPhone or iPad, so we changed those to pressing the CONTROL key while tapping a key from 1 to 9.

The games were released about two weeks ago, and we’re getting great feedback.


Blindfold Bird Songs

One of the testers asked if I could create a level of Blindfold Color Crush that had common household sounds and another level of bird songs.  Blindfold Color Crush is a matching game where you have to get three identical items adjacent to each other, by swapping them with other items.  It’s a variant of Candy Crush or Bejeweled.

The household sounds were easy to find, but the bird songs were harder.  I licensed some audio sound effects that included over 80 bird songs, and picked the best for a new level of Color Crush.

When I described the new version to the testers, they thought I should create a bird song training game.  I learned that several schools for the blind offer classes in recognizing bird songs, and they thought the game would be both educational and enjoyable.

The first version of the game was easy – it listed the names of the birds in one column, and the bird songs in another column.  You first pick bird, and then flick through the songs until you find a match.  The first level starts out with 3 birds and 3 songs, and each new level adds another 2 birds and 2 songs.  Pretty soon, you are playing a naming game with over 50 birds.

Once game was bug-free (pardon the pun), someone suggested adding a memory game to Blindfold Bird Songs.  The matching game starts off with 6 squares in a 2 row by 3 column grid, with each bird song appearing twice in the grid.  The goal is to remember where you heard each bird, and find the corresponding match.  After many levels, the grid has about 50 squares, and you must find the match each of the 25 bird songs.

Scoring this game was little difficult – I needed a scoring system that would reward good answers, but penalize wrong ones.  I didn’t want people to play just randomly.  When you find a match, you earn 2 points, but lose 1 point for each wrong answer.

The final piece was to give a reward for finishing each level.  My first reward was to give a different humorous saying for completing a level, such as the quote by Steven Wright “Everywhere is within walking distance if you have the time”.  Several people pointed out that the humor quotes have nothing to do with the game, so I changed the reward to bird facts like “Penguins can jump as high as 6 feet in the air”.

The game has been quite a hit, and now people are asking for variations on this game.




Blindfold Game Fanfares

I’m always looking for ways to involve the blindness and low vision community in the creation of games, and up until now, other than providing ideas for new games, or testing the games, I didn’t have much.

One of testers asked if he could record himself on a trumpet playing a winning sound, and have it used in the games  He did several, and instead of replacing the current winning sound with his, I decided to improve the game architecture to let the game player pick the sound.

The current winning and losing sounds are:

I created a new screen where the game player can pick their favorite winning and losing sounds, and they can change it at any time.

As people create new winning and losing sounds, I just upload their contributed sounds to the cloud, and the games automatically pick up the new sounds.  We’ve added several great sounds, and I get more contributions every month month.

Here are some of the best contributions:

Blindfold Madness: Braille Keyboards

When I talked about Phrase Madness last time, I mentioned that people thought the iPhone game was much worse than the Windows version – it took too long to find the matching phrase you want by scrolling up and down in the list.

braille display and keyboard

About the same time, I was working on a project with another developer where we definitely needed to use a keyboard attached to an iPhone.  I didn’t know at that time that many visually impaired people use a braille display/keyboard with their iPhone or iPad.

A braille display/keyboard serves two purposes.  It has a set of 6 metal pins that represent each letter of the alphabet, and the display is 20 to 40 letters long, so a blind person can read the screen using braille instead of listening to words using voice over.  It also has 6 or more buttons so they can type instead of using voice dictation, or typing with voice over.  I’ll write another blog on how you can put your phone into voice over mode so you can understand how all that works.

Anyway, I had to improve all of the Blindfold Games to start using a keyboard.  Both a standard bluetooth keyboard and a braille bluetooth keyboard work the same way.  You just tell the phone that you are using a keyboard, and instead of typing with the pop-up screen keyboard, you type the same way you would use a keyboard on a PC or Mac.

It took a few days to develop a generic way of using a keyboard with the Blindfold Games, but once it was done, I changed Phrase Madness to go back to letters instead of numbers.  Now, with an attached keyboard, you just type the letter of the position where the phrase is location.  If you aren’t using a keyboard, and you swipe up or down to get to the position you want, the game speaks the letter name, such as fox for the letter F.

We released the game after another few rounds of testing, and so far, it seems to be a hit.
