appmarsh.com | Accessibility Apps Get Assist from Bluetooth Buttons

Ever pay attention of Microsoft Soundscape? We hadn’t, both. However it appears it and an identical apps like Blindsquare supply other folks with imaginative and prescient issues context about their atmosphere. The app is made to run within the background of the person’s cellular software and reply to media controls, however if you’re navigating round with a cane, attending to media controls on a telephone or perhaps a headset is probably not very handy. [Jazzang] set out to build buttons that could control apps like this which may be built-in with a cane or differently situated in a handy location.

There are four buttons of hobby. Play/pause, Subsequent, Again, and House. There may be additionally a mute button and an extra button you’ll use with the telephone’s accessibility settings. Every button has a distinct serve as for Soundscape. As an example, Subsequent will describe the focal point in entrance of you. Soundscape runs on an iPhone so Bluetooth is the most obvious selection for developing the buttons.

To simplify issues, the venture makes use of an Adafruit Feather nRF52 Bluefruit board. For the reason that it is Arduino appropriate and offers a Bluetooth Human Interface Instrument (HID) out of the field, there may be nearly not anything else to do for the {hardware} however twine up the switches and a few pull up resistors. That might make the circuit simple to stay nearly anyplace.

Instrument-wise, issues don’t seem to be too arduous both. The library supplies the entire Bluetooth HID software trappings you wish to have, and as soon as that is arrange, it’s beautiful easy to ship keys to the telephone. It is a nice instance of how simple so many tasks have become because of the supply of abstractions that take care of the entire main points. Since a Bluetooth HID software is only a keyboard, you’ll most certainly recall to mind many different makes use of for this setup with simply small adjustments within the instrument.

We covered the Bluefruit again when it first gave the impression. We do not learn about mounting this to a cane, however we do have in mind one thing an identical attached to a sword.
