DirectTransfer

DirectTransfer allows easy transfer of notes previously created on a cell phone tech braille system to a connected computer system. The special feature is that no transfer program is necessary, since the transfer of the note data is done like the input via a keyboard. If the Braille system is connected to a computer system wirelessly via Bluetooth or via USB, the computer system is recognized as a keyboard in addition to the Braille display function. DirectTransfer enables the transfer of note data as a sequence of emulated keystrokes. Without any additional program or installation of software components, direct access to the notes on a cell phone tech braille system is thus possible.

How does the data transfer between computer and Braille system work?

In the Handy Tech invention DirectTransfer, the data connection between the Braille system and the computer system is used in such a way that the data emulates keystrokes during transfer, as with a connected keyboard. The key advantage of using the keyboard connection is that all computer systems can be operated using the keyboard even before a transfer program is installed, and even before the operating system is installed. Only this feature makes it possible to install or configure computer systems as well. The invention makes use of the reliable connection of a keyboard to a computer system even of different operating systems.

Braille systems such as Active Braille or Active Star allow text to be entered via an integrated keyboard for dot matrix input, or via an externally connected keyboard. The entries are stored internally in the braille system. The data is stored internally as characters in a standard format such as ASCII or Unicode, regardless of whether the input is made via a Braille keyboard or a standard keyboard.

By suitably assigning and converting the stored data to the corresponding keystrokes on a keyboard connected to the computer, direct data transfer to the computer system is made possible. If, for example, the Handy Tech Braille system is connected to a computer via a USB interface, the data transfer takes place in such a way that the inputs are interpreted by the computer system as keystrokes of a keyboard connected via USB.

 

Transfer data easily via key combination

A key combination triggers complete notes or partial sections of notes in the Braille system to be transmitted to the computer as emulated keystrokes. In order for the emulated keystrokes to allow text transmission to a computer, it is necessary that the cursor of the computer system is in a position intended for text input.
For example, if one wishes to send a note by e-mail, then in the e-mail program, after selecting the recipient and entering the subject in the text input portion of the e-mail, one can insert the note as an emulated sequence of keystrokes from the Braille system according to the invention. The data is inserted at the position of the cursor.

In Braille systems to which an external keyboard can be connected, data can also be transferred from the computer system to the Braille system by emulating keystrokes, according to the invention. For this purpose, the internal note function of the Braille system is activated and the cursor is placed at the desired text position. A keyboard emulation, which may be part of the computer's Braille system control program, transfers the data as a sequence of keystrokes.
By coupling two braille systems via their keyboard interfaces, data transfer between the devices is also realized according to the invention.
