industry-grade latex gloves that
are used in hospitals and
chemical laboratories.
Both 2D and 3D scanning systems have now been updated
to include additional security features which can assess the
user’s emotions and measure the body temperature when the
TBS system scans the person. If abnormal body tempera-
ture is registered, TBS will not authorize the user. Similarly,
gesture controls have also been included to mitigate the use
of sign language and physical movements from end-users.
The COVID-19 outbreak has
increased the demand for CT;
thus TBS can help companies provide safer working envi-
ronments for their employees [

Thermal Scanner Systems/Temperature Detecting
Cameras
Both schemes use thermal sensor modules to identify the
body temperature of an individual and alert them if their
body temperature is outside the nominal level. Touchless
biometrics have been utilized in the healthcare sector too.
Body area networks (BAN),
wireless body area networks
(WBAN), body sensor networks (BSN), or medical body
area networks can assist in comprehensive healthcare mon-
itoring by monitoring body vital processes and tracking
patient activities, etc.
Wearable Bands
Wearable bands are smart electronic devices worn over the
surface of the skin, e.g., typically over the wrist.
They ana-
lyze basic information like body blood pressure, heart rate,
oxygen saturation, etc. and can also track activities (walking,
running, sleeping, etc.). Apple smartwatches, Fitbit, Garmin,
Suunto,
Polar products, etc. are some of the most commonly
used wearable devices available in the market.
HoloTouch
This technology uses human-machine interface (HMI) and
works by allowing people to pass their finger through holo-
graphic images or buttons or keyboards which are floating
in the air. Then, an infrared sensor detects and transmits the
measurement to the detection software as shown in Fig.

.
Other similar applications to
Holotouch include optical
computers, biomedical imaging, scanning and diagnosis,
and destructive or non-destructive testing in military appli-
cations. Some of the applications of HoloTouch have been
used in China for touchless holographic elevators,
hotels and
room sections, or for food orders and payments.
