“Neuromotor” computer interface

A wristband that allows people to interact with computers through
hand gestures could revolutionise computing, particularly for
those with reduced mobility or finger amputations

Compute capsule:
Digitises signals and
streams data to
computer using
Bluetooth

Computer: Hand gestures
translated into virtual
navigation and
selection
commands

One size fits all:
Adjustable gap
between segments –
placed over area of
low muscle density

Wristband: Consists
of 48 electrode sensors
configured across 16
segments (channels).
Each channel tracks
movement activity
from inside arm

Handwriting:
Sensors are
acute enough
to recognise
writing and
transcribe
into text

Speed:
21 words
per minute
