Note: View updates and news at the bottom of this webpage

Armed with a shotgun, machete and surrounded by zombies, Jack is certain to introduce those rubber-ducky-stealing alien zombies to a world of pain! There's only one problem: Jack is blind. Use your hearing to locate the zombies before they attack. Pull the trigger or machete the hell out of 'm to retake Jack’s rubber ducky. Use the headphones to experience the 3D sound. The app uses GPS and Compass readings.The Alien Zombies will attack you from all sides. At first they come one by one, in a later version, we will add different Alien Zombie Monsters, firearms and even multiplayer possibilities. The app uses a custom built audio augmented reality engine that generates 360 degrees sound through normal headphones. Turn around and the sound will also turn. Go to the itunes store and install the app on your iPhone now.

This is Jack

Jack is a bad tempored alcoholic who doesn't care for anything but his rubber ducky. All Jack does is sit at home, jobless, looking at action movies or p#&n. If someone he doesn't know walks on his land, the shotgun and machete do the talking…

Devices that Rubber Ducky works on

rubberducky screenshotThe app works on iPhone 3gs. But it works faster on later iPhone models. The app also works on ipad 2and 3 with wi-fi + 3G. The app does NOT work on ipod (because it needs GPS and compass). The app also does not work on Android because at the moment, they do not support hardware acceleration necessary for fast processing of the data and AR audio.

3D audio augmented reality engine gives new meaning to First Person Shooter apps

Because the main character is blind, there are no visuals on the screen that are relevant to survival. Just learn where the buttons are, close your eyes and trust your ears. The 3D Audio Augmented Reality Engine uses intelligent algorithms to reproduce how our ears percieve the world around us. This game literally demands a killer hearing… 

Augmented Audio Reality (AAR) 

The app is an example of the possibilities of our 3D Audio Augmented Reality technology. The same technology can be used for other (non-violent) games, interactive audioguides, citytours and applications. The technology is accessible for the visually impaired. The audio you hear is depending on your position. If the sound is behind you, it sounds like it is behind you. If you turn around, the sound also turns. This way blind listeners also know exactly where to 'look'. This is naturally very handy when seeking out Alien Zombie Monsters, but can also be used to place virtual poets in a real garden. We used HRTF examples to calculate the correct sounds and optimize the effect. In Rubber Ducky, the result is that you can hear Alien Zombie Monsters coming towards you and can turn to face and shoot them immediately ... before they eat you. 

Why did we make this game?

We made this game because a lot of blind people wanted a shooter. We did this earlier with the game Demor. This iPhone app is just the start. We plan to enhance the app with more levels, more zombies, more weapons, more highscores (now not available) and everything else you ask us to add. Also we will add more directional effects in the next version. We hope you like the idea. Let us know what you want after this.

Why only on iPhone?

The app is currently only available on the iPhone because iPhone offers hardware acceleration.

Screenshot detail van AppleVis website met bespreking van Rubber Ducky15 June 2012, Utrecht: Where's My Rubber Ducky was reviewed on the Applevis forum. Great reactions by users playing the game. Also great advice for the next updates. We want to add more weapons, different enemy species and more story and gameplay in the next version. By the way, the engine itself makes it possible to place the monsters outside and do audio based multiplayer games.  Some reactions:

"I tried this app when I finished reading this post, and found the experience interesting and cool. The developers did well with configuring the real-time positions, because I was able to turn in the direction of the zombies without difficulties" (Bahzad on 13 June).

"How in the world are you guys getting al the way up to level 17! I keep dieing at level 3... This game is so fun and i can't wait to see what they add next!" (nk1229 on 14 June)

101tv BNN Dutch Television visiting us for review 4 persons in room, one with camera27 April 2012, Utrecht: BNN 101tv visited us for an interview and to play the game for their game review program. We all had great fun walking up our stairs pretending to be Zombies. Here you see a picture of the interview. Stefan is doing his best to explain why the game does not have graphics and how the spectacular 3d sound works. We explained that this is just the beginning of loads of applications that could be made using 3D sound. Naturally we stressed the accessibility for the blind. Hope their review is ok.

Two duckies with braille attached to their neck waiting for a new owner12 April 2012, Houten: We pre-tested Rubber Ducky at the Ziezo 2012 trade fair in Houten (Netherlands). Many blind people go there and they tried out the test-app. We received some great tips for the next version. But first we will launch this one. We made the app between December and January this year as a spin-off of another project for the blind. If you visited the Ziezo 2012 and have tips for us, please visit us on Facebook or use Twitter to tell us how many Alien Zombies you shot today.
