Abstract

Text-to-touch techniques, in accordance with embodiment of the present technology, include apparatuses and methods for receiving content including textual portions and non-textual portions. The textual portions include letters, select words, numbers and punctuation having recognized Braille codes. The non-textual portions may include metadata, graphics, formatting, decorations, hyperlinks, radio buttons, submit buttons, check boxes, windows, icons, fields and/or the like. The systems and methods convert the textual portion to Braille codes and select non-textual portions to haptic feedback. The Braille code may then be output to a user. In addition, the haptic feedback associated with various Braille codes may also be output to the user along the associated Braille codes.

First claim

What is claimed is:

1. A system comprising:
a Braille encoder to convert textual portions of a content to a plurality of Braille codes;
a haptic output controller to convert non-textual portions of the content to haptic feedback;
a plurality of Braille cells or a Braille wheel to output the Braille codes and selectively output the haptic feedback with corresponding Braille codes, and
a position input controller to determine a position of a user relative to one or more of the plurality of Braille cells with the position input controller selectively outputting the haptic feedback representing the non-textual portions of the content responsive to a determination that the position of the user is proximate one or more of the Braille cells outputting the corresponding Braille codes.

2. The system according to claim 1 , wherein a non-textual portion of the content is a first non-textual portion of the content, and the haptic feedback has a first type, a first characteristic, or a first parameter indicative of the first non-textual portion of the content, a type of the first non-textual portion of the content, a class of the first non-textual portion of the content, a characteristic of the first non-textual portion of the content, or a parameter of the first non-textual portion of the content and the haptic feedback has a second type, characteristic, or parameter indicative of a second non-textual portion of the content, a type of the second non-textual portion of the content, a class of the second non-textual portion of the content, a characteristic of the second non-textual portion of the content, or a parameter of the second non-textual portion of the content.

3. The system according to claim 1 , wherein the non-textual portion of the content comprises a hyperlink and the haptic feedback comprises a vibration to indicate the hyperlink.

4. The system according to claim 1 , further comprising a force input controller to determine a force applied by a user to one or more of the plurality of Braille cells or the Braille wheel.

5. The system according to claim 4 , further comprising the force input controller to further output a signal indicative of selection of a portion of textual content corresponding to the Braille codes output on the one or more Braille cells or the Braille wheel when a force having a given characteristic is sensed on the one or more of the plurality of Braille cells or the Braille wheel.
