T-shirt message

QR code is a two-dimensional bar code, which has been developed in Japan in 1994. It has become extremely popular there, where standards were adopted in January 1999, where posters, and ads often include QR codes and where the most mobile phones are already able to read. In June 2000, it has become an international standard. It became even more popular after it was launched and quickly spreaded around the world.

Our aim

Kitchen Budapest researchers started to use QR codes when printed on T-shirts. Our clothes are already a media for transmitting message in color, style, or by printed graphics, and if the message is encrypted it is even more exciting. It is really a geek thing, to have our facebook or iwiw id or status message on the T-shirt in the form of QR codes.

How does it work?

QR code, as with all encoding there are two phase to talk about – encoding when the code is created from the message, and decoding when the code is translated back to the original message, hopefully without error. The QR code is optimized for to be effectively and quickly read by low resolution cheap cameras, even if the image is blurred or distorted. QR is the abbreviation of “quick response”, also refers to this meaning, however, decoding on slow phones can take up to10 seconds.

Current state:

The workshop, held in Kitchen Budapest presented some options about how to make our own unique QR codes, to broadcast encoded message by printed QR codes, handmade QR codes, or making QR codes by tricky textile skills, by which our code on T-shirt will be changeable. Later we will brainstorm about and write iphone applications on the creative use of QR codes.
