Description

“Chromatic Vision Simulator” is a color vision simulation tool which simulates the color vision of color vision deficiencies. This software is developed by Kazunori Asada (Ph.D. medical science and Ph.D. media design), based on the research in color science.

About 5% of men have difficulty distinguishing red and green, or recognizing dark red. Such color deficiency can be classified into three major categories: protanope / Protanomal, Deuteranope / Deuteranomal and Tritanope / Tritanomal.

Color deficiencies are the inability to tell differences between some colors other people can easily distinguish. People with different types of color vision deficiency perceive colors differently. For example, individuals diagnosed as Protan or Deutan cannot perceive differences between red and green, and pink and cyan.

These color visions are predictable by calculating working of the cone cells that perceives the color to some degree.

"Chromatic Vision Simulator" makes simulated images of each color vision type from built-in Camera or Photos and shows you how people with specific types of color vision sees the world in real-time.

 Free in iOS App Store

Version 2.01

2.0 -> 2.01:

- The bug that sometimes mistakes the color vision type letters in stored images is fixed.

- The shutter sound is change to off when the silent switch is on.

1.01 -> 2.0:

"Chromatic Vision Simulator" is updated to version 2.0 with many new cool functions.

- Universal Application
Compatible with iPhone 3GS, iPhone 4, iPod Touch 4G and iPad 2.

- High Resolution
With iPad 2, it works with 768 x 1024 high resolution. You can see details clearly.

- Parallel Simulation
Supports realtime parallel simulations (dual and quad) of different types of color vision simultaneously.
The dual mode shows a normal color vision image (type C) and a one of dichromat color vision (type P or D or T) simulation image together. And the quad mode shows all four types (C, P, D and T) simulation images together.

- Rotation
Supports native portrait and landscape orientations user interface.

- Digital Zoom (max 3x)
A digital 3x zoom is supported. You can zoom in and out simulated images by pinching with two-finger.

- Front Camera
A front camera is now enabled on iPhone 4, iPod Touch 4G and iPad 2.

- Storing Simulated Images
Simulated images including the dual and the quad mode can be stored in the "Photo Album".

- Geotag
A "Geometry tag" (geotag) can be saved in simulation images.
A geotag is added when you allow this app to use location data by sliding the switch to "ON" in "Settings" - "Location Services" page.
