Increasingly, we are recognizing that mobile devices are an important way to connect people to learning and health tools. However, text interfaces can be very problematic for individuals with poor literacy. Enter QR codes. Although we may associate them with high tech uses, they can play a valuable role in overcoming some text literacy challenges that can make the effective use of mobile phones impossible for some.
This video by adaptivepath.com describing the Mobiglyph project demonstrates how QR codes can help reduce the digital divide.
You can read more about this mobile literacy project here on the adaptive path blog as well as here on the PSFK blog, where I first learned about this project.
