The idea is to add a Qr code to signs within the University environment.

Qr codes are easily generated by open source software, free software and online tools, and may improve the awareness about the surrounding space of students having visual impairments and dislexia.

Use a qr (quick response) code generator,  there are different open source and free software running on any operative system, to create a code containing all the information.

Students may use their smartphone with a text speech software to know the content of the signs.

You may use it for:

• Door signs in university building;
• Labels in museums with direct link to;
• In book covers or leaflets with a link to URL containing text, teacher lectures etc 
• Business card;
• Calendars of lectures, exams.
• ...

Limitations

• There is no tactile universal code to identify the proximity of a QR code;
• the maximum number of characters in text qr code is 4.296, but a grid readable by smartphones without hgh definition camera is about 170 char;
• there are no hardware supllies and standards to warn you are entering a "qr coded" area.

Denso Wave owns the patent rights on QR codes, but has chosen not to exercise them, so the use of QR codes is free of any license. The QR code is clearly defined and published as an ISO standard.
