Method for a Braille feedback keyboard

Disclosed is a method for a Braille feedback keyboard. Benefits include improved user productivity, and improved functionality.

Background

              Conventional solutions include a range of software and hardware products for impaired users. One system makes use of a pad of push-up pins. By resting his or her hand upon the pad of pins, the user receives a constant stream of output from a computer. The computer interprets the text on-screen and sends the data to the device, where the user receives feedback from the push-up pin pad. This device is not directly related to keyboards or input.

              Another conventional solution is the Braille strip that blind users can lay in front of a keyboard. The strip produces Braille symbols one row at a time while the user's fingers rest on the strip. This is a separate peripheral with separate setup and usage criteria.

Description

              The disclosed method is a device that provides Braille characters on a keyboard using dynamically actuated pins. The sightless user is able to type by feel read from the keys. Pin configurations can be changed on the default position keys, providing a row of text to the user.

              For example, a blind person chats with someone online. The user types a message and uses a control key to activate read mode on the keys where her fingers rest. A second key activates the next line of characters, and the two control keys navigate through the entire body of text.

              All passive keys have fixed, standard Braille features for appropriate characters (see Figure 1). Active keys each have a set of six actua...
