Diplopia received an honorable mention at this year's IEEE VR conference.

It was great to see so many people who were excited about VR, its applications, and the direction it was headed. We received a lot of valuable feedback from people who tried playing Diplopia. The conference was an incredible experience and we're looking forward to attending IEEE VR 2015 next year in France. Hope to see some of you there!

A Game Designed To Help Lazy Eye

Diplopia is a virtual reality game designed to help amblyopia (lazy eye) and strabismus (crossed eye) using the Oculus Rift and Leap Motion controller.

Watch this video for a quick and simple explanation of Diplopia and how it works. The gameplay is old, for new gameplay check the next video.

Strabismus, better known as crossed eye, is present in about 4% of children. In those affected both eyes do not line up properly causing diplopia (double vision), amblyopia (lazy eye), and loss of vision in one or both eyes. Since the brain receives conflicting information from the two eyes it often learns to disregard the weaker of the two, suppressing it. This leads to a loss of depth perception and 3D vision.

It was long thought that once a person's brain had learned to suppress one of their eyes that they could only unlearn this suppression before a 'critical age' of between 8 and 12 years old. Only recently has it been shown that certain kinds of therapies (including video games) can actually treat amblyopia past adolescence, allowing for the possibility of restoring 3D vision in adults.

Diplopia takes advantage of the wealth of new information in scientific studies that have come out in the past couple of years to create an experience that will hopefully help people who have a suppressed eye to use that eye in conjunction with their good one.

Whether you have amblyopia or not, Diplopia is a game that is fun and challenging to play for everyone. All eye-training modes, Oculus Rift support, and Leap Motion control will be totally optional.

The Game

A game designed to help lazy eye 

In the game you bounce a ball around a room with a paddle to destroy blocks, unlocking power ups. By manipulating the contrast of game elements such as the bricks, ball, and paddle you can force the brain to integrate the two images.  By showing only some of the game elements to each eye Diplopia forces the player to incorporate information coming from both in order to win.  

Here 'Dilpopia Mode' is enabled, the game shows the ball and bright bricks to the left eye while showing the paddle and dark bricks to the right. This forces the player's brain to utilize both eyes to win.

These strategies have been used in treatments that have been shown to be up to 6 times more effective than the typical treatment, patching, which is often ineffective for children because of how extremely unpleasant it can be.  Diplopia will offer a fun, effective, alternative to patching that can keep the attention of a person long enough to help them.

I was told by doctors my whole life that I could never see in three dimensions like everyone else.  By backing this project you can give the gift of better vision to those of us who lack it.

Features

There will be several testing modes to measure suppression and the angle and type of offset between the eyes. Using these testing modes along with optional player surveys I hope to collect data about what techniques are best for treatment. This data would be released to the public after stripping all personal information from it.

There will be tests for color blindness, visual acuity (if resolution permits), and visual field as well.

Diplopia could be an improvement over other options because both the gameplay and the game are in 3 dimensions.  This means that you are training your eyes in an environment that is more like real life than a simple 2D game.  The ball is moving quickly in three dimensions, forcing the player to track it quickly to win.  This exercises the eye more than a slower paced game with less movement.

Do You Have Amblyopia But Can't Afford A Rift?

Thanks to the generosity of our backers we have already raised the money to pay for more than 140 free copies of the game and 13 Oculus Rifts!

Rifts and games will go to those who need them most. You can apply for one here!

You can help!

Many people have expressed interest in helping the project in many ways. Diplopia would be happy to accept help in many forms.

We could use help from testers with amblyopia and/or strabismus. Artists, programmers, 3D modelers, and video game enthusiasts can also help!

You can always help by telling your friends about Diplopia and sharing us on facebook, twitter, and the rest of the web.

Suppported Technologies

Oculus Rift. The Oculus Rift makes it all possible.  It is a head-mounted virtual reality display which allows Diplopia to send different images to each eye.  You can play the game in 'normal' mode as a regular video game without a Rift, but you can't use the 'Diplopia' mode to help with amblyopia unless you have one.   It really feels like you are inside of a new place when you are using it.

Leap Motion. The Leap Motion controller is a high resolution 3D gesture tracking device.  It can be difficult to find the keyboard and mouse while you are inside virtual reality.  Using a Leap Motion controller you can easily see your virtual hands to control things around you, making it quite a bit easier to play Diplopia.

Razer Hydra. The Razer Hydra is a motion tracked game controller with a joystick and several buttons.  This also solves the problem of finding your keys on the keyboard while in virtual reality, though it is more expensive and less useful than the Leap Motion outside of games.

nVidia 3D Vision. 3D Vision is a stereoscopic gaming kit from Nvidia which consists of LC shutter glasses and driver software which enables stereoscopic vision for any Direct3D game.  This will be an alternative to the Oculus Rift, but it is more expensive than the Rift.

Kinect. The Kinect is a full body motion capture device released by Microsoft.
