n AI-Equipped Eyeglasses
Read Silent Speech
AI glasses with a silentspeech
recognition interface
use acoustic- sensing and artificial
intelligence to continuously
recognize up to 31 unvocalized
commands, based
on lip and mouth movements.
The low-power, wearable
interface requires just a
few minutes of user training data before recognizes commands
and can be run on a smartphone.
Outfitted with a pair of microphones and speakers smaller
than pencil erasers, the EchoSpeech glasses become a wearable
AI-powered sonar system, sending and receiving soundwaves
across the face and sensing mouth movements. A deep
learning algorithm then analyzes these echo profiles in real
time, with about 95 percent accuracy.
Recently, the lab has shifted away from cameras and toward
acoustic sensing to track face and body movements, citing
improved battery life; tighter security and privacy; and smaller,
more compact hardware. EchoSpeech builds off the lab's
similar acoustic-sensing device called EarIO, a wearable earbud
that tracks facial movements. (Image credit: Cornell)

n Sensor System
Decreases Fall Risk for
Older Adults
A research team has
designed a fall-risk assessment
system that enables
doctors to create personalized
risk-management strategies
for patients based on
their individual move ment
patterns at home.
The system includes a
wearable device, a homemapping
and movementmonitoring
component, and
an artificial intelligencemediated
data- processing element. The wearable device tracks
location with an ultrawideband sensor. It tracks movement
with an accelerometer and tracks time with a real-time clock.
Patients can press a button enables if they are dizzy.
Everything is written to a micro-SD card. The system includes
a lidar scanner mounted on a tripod that can map the
layout of a room, including the furniture. The lidar scanner
sends out a signal and detects where the walls are. (Image credit:
