This option is usually at the bottom right. If you don’t use Gboard, your options might be different.

TalkBack braille keyboard is available in English, Ancient Greek, Arabic, Catalan, Central Kurdish, Croatian, Czech, Danish, Dutch, Estonian, Finnish, French, German, Greek, Gujarati, Hungarian, Italian, Khmer, Malayalam, Marathi, Nepali, Northern Sami, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Sinhala, Slovak, Spanish, Swedish, Tamil, Telugu, Turkish, Ukrainian, Urdu, Vietnamese, and Welsh. With the TalkBack braille keyboard, you can use 6 fingers on your screen to enter 6-dot braille. 55% of them went with what might seem the most obvious choice (at least in hindsight): counting from left to right and top down, putting the zero at the bottom (123,456,789,0).Important: BrailleBack is no longer required to connect to a braille display. 7% of participants went down before going right (147,258,369,0). Ultimately, 8% of people emulated a calculator layout (789,456,123,0). What seems familiar to us now was entirely new territory for these people, except the few who had used calculators. Sample test sheet comparing different key configurations across six layoutsīut there was still a question of where to put the numbers in the grid, so testers were given blank layouts asked to fill them in. They disliked the vertical tower variant but actually made fewer mistakes on it (in part because they were going slower). Performance and preference differences, though, were deemed to be fairly small overall across the five finalists, so for engineering reasons Bell went with the layout we know today. Testers expressed a preference for and were able to type faster on the familiar rotary-style ones. In the end, they narrowed it down to five layouts, including: the familiar grid (which we still use to this day) two circular variants (inspired by existing rotary phones), one with two vertical columns and one with two horizontal rows (each row or column containing five numbers). The researchers whittled down the list by seeing how fast and accurately people could type in numbers on different pad arrangements. Their designers came up with sixteen distinct options shown below (eighteen total but two are duplicated: II-A + VI-B and IV-A + VI-A).īell Labs had a number of human factors experts, so they started bringing personnel in to brainstorm and test these different ideas. Some may look impractical if not downright silly in hindsight, but Bell wanted to make sure to examine the problem from all possible angles. As such, other variations were explored as well, including calculator-style grids, bowling-alley triangles, stair-like angles, cross-shaped configurations and more. Still, Bell saw this as an opportunity to start from scratch, going back to the drawing board and trying out all kinds of creative alternatives. It seemed from the start that this approach might win out in the end. The first layout solution proposed was a carryover from existing phones: numbers laid out in a circle. Touch-tone phones would make dialing much faster and easier. Rotary telephones could be time-consuming to operate - for those unfamiliar: you had to spin the dial for each number, then let the wheel spin back, repeating the process over and over again. As rotary-dial phones began to be replaced by touch-tone variants, a design challenge (and opportunity) arose around how this new system would work.
