Kunyoong Ibc KBD-002 Bdot Wearable Braille Input Bluetooth Keyboard
BDOT INTRODUCTION
Bdot is a keyboard for exclusive use of braille that connects to a smart
device (Android/iOS/Windows/MAC, etc.) via Bluetooth as a physical input
device. It is a wearable braille keyboard that is convenient to carry with its
wristband design. The main body consists of 4 keys each on both bands and 10
keys with 2 keys, providing faster and more convenient functions than
conventional keyboard products. When the main body is opened, the power is
automatically turned on, and 4 to the left of the keyboard (1,2,3,7 points), 4
to the right (4,5,6,8 points), 2 in the middle (space 1, space 2). Space 1 and
Space 2 function as a space to add a general space, and when two spaces are
pressed at the same time, they function as a mode key. When charging, attach
it to the back of Bdot using the enclosed magnetic cable to charge (there is a
magnetic polarity, so you need to attach it according to the polarity to
connect) Bdot can be used with iOS 9.0.0 or higher and Android 4.4.4 or
higher, but we recommend using it with the latest OS version.
