What is this BS EN 62665 - Texture map for auditory presentation of printed texts about?  

BS EN 62665 discusses multimedia systems and equipment with a focus on texture maps for the auditory presentation of printed texts. In order to generate a texture map for auditory presentation of printed text information, BS EN 62665 specifies 

• A text encoding scheme to generate a texture map 
• A physical shape and dimension of the texture map for printing 
• Additional features for texture map printing 
• Texture map decoding and an auditory presentation of decoded texts 

These specifications enable the interchange of documents and publications between visually impaired and non-impaired people. 

Who is BS EN 62665 - Texture map for auditory presentation of printed texts for? 

BS EN 62665 on texture map for auditory presentation of printed texts is useful for: 

• E-book publishing platform 
• E-book developments  
• Publishers 
• Other equipment that uses audio interface (television, phones) 

Why should you use BS EN 62665 - Texture map for auditory presentation of printed texts?  

Information interchange via printed documents between blind or visually impaired people has been carried out by using Braille. However, in order to be able to read Braille, particular tuition is required. Learning Braille is very difficult for aged as well as visually non-impaired people. 

Printed documents with texts and text-encoded texture maps can be interchanged by ordinary circulation or publication mechanisms. They are readable as ordinary printed materials and comprehensible by blind or visually impaired people with the support of decoding and auditory presentation equipment. 

BS EN 62665 provides a text encoding scheme to generate a texture map and texture map decoding and an auditory presentation of decoded texts as it is necessary to print a texture map at an appropriate position with the correct size on paper, because an auditory presentation equipment reads the texture map at a fixed position.
