Bonocle Tutorial

Beta Phase

Bonocle Platform

Version: Beta

Bonocle’s Beta version is the first prototype of our entertainment platform. Our goal is to create a small, portable device that can provide access to a growing range of software apps and benefits.


Bonocle is in the shape of a computer mouse. It has one braille cell in the top most and widest section of the device. The braille cell is surrounded by three buttons. A previous button located on the left of the braille cell. A next button located on the right and an action button below the braille cell.


The device is going to have a matte black finish with the action button colored teal for a nice contrast. On the back of the device is the On/Off switch and next to it is an opening to allow the laser beam to pass through.

Read time: 3 mins

This app allows you to read content in braille using Bonocle. It features multiple customizable options to match your preferred reading style and setup. The app supports PDF file formats as well as full support for Bookshare.

  1. To open any PDF with the Bonocle app, simply use the “open with” feature on iOS and navigate through the list to the Bonocle reader app.
  2.  Upon launching the app, you are presented with a list of the books/documents that has been previously opened with the app. You can navigate through the list using the voice over feature and select one of the documents to initiate the bluetooth connection with Bonocle.
  3. Bonocle will vibrate to signal that the connection is successful. You can then start reading by sliding Bonocle on any surface to the right to move through the content. Similarly, you can slide Bonocle to the left to move backwards through the text.
  4. While reading, you can move to the next page by clicking the next button. Move to the previous page by clicking the previous button. The action button will stop/start in auto scroll and tilt mode. In motion mode, the action button will read out loud the current word you are reading.
  5. You can add a bookmark by navigating to the bookmark option using voice over in the app header.
  6. To change the settings, navigate to the app settings using voice over. The settings list contains the following:

Braille Cell Mode: This option lets you change the way Bonocle acts when switching between letters.

  • Vibrate Mode: Bonocle will send a small haptic nudge to signal movement through the text letter by letter.
  • Flush Mode: The braille cell will return to neutral position after each letter is displayed and before moving to the next letter.

Braille Code: This option allows you to change through the different braille codes. Default braille code is UEB Grade 2

Reading Mode: Here you can switch between the different ways you can read with Bonocle.

  • Motion Mode: This is the default mode. You slide Bonocle on top of any surface to navigate through the text. Sliding Bonocle to the right allows you to move through the text while sliding to the left lets you go backwards through the text to re-read a letter, word or sentence.
  • Auto Scroll Mode: In this mode, the braille cell will progress through the text automatically.
  • Tilt Mode: In this mode, the braille cell will move through the text as you tilt the device clockwise. You can also move backwards through the text by tilting the device anti-clockwise.

Speed/Spacing: Under this setting, you can customize further the spaces needed to move between letters and lines. You can also control the speed at which the letters change in both Auto-scroll and Tilt Modes.

  • Horizontal Spacing: Here you can change the virtual space between letters while sliding left and right in Motion Mode.
  • Vertical Spacing: Here you can change the virtual space between lines while sliding up and down in Motion Mode.
  • Auto-Scroll Speed: Here you can change the scrolling speed between letters in Auto-Scroll and Tilt Modes.

Kindly note, Bonocle will be collecting data on your reading behavior for statistical research and development purposes. We are not collecting data on the content you are reading nor are we able to view it. Data collected includes reading speed, preferred reading mode and potential repetitive behavior.
