Touchless touch screens allow interaction without direct physical contact by using infrared sensors or gesture recognition. They started being experimented with in the 1980s and gained popularity with Microsoft Kinect in 2010. Touchless screens can now be found in applications like public information kiosks, medical equipment, gaming consoles, and smart homes. Researchers continue improving the technology to make touchless screens more accurate, affordable, accessible, and environmentally friendly.

3. Touchless touch screens work without direct
physical contact. They either use infrared
sensors to detect motion or interpret hand
gestures, enabling interaction without touching
the screen directly.

4. Touchless touch screens
enable interaction without
physical contact.
Example: using infrared
sensors or gestures to
control a screen without
touching it directly.

5. Touchless touch screens started
with early experiments in the 1980s,
gained momentum with Microsoft's
Kinect in 2010, and have since
evolved for hands-free interaction
using gestures and infrared
technology.

6. Touchless touch screens can use
infrared sensors that detect
interruptions in an infrared field or
cameras to recognize gestures,
allowing interaction without physical
touch.

8. • Touchless touchscreens often utilize
technologies like infrared sensors,
capacitive sensors, or camera-based
systems.
• Infrared sensors detect interruptions in
infrared light beams, while capacitive
sensors respond to changes in electrical
capacitance. Camera-based systems use
computer vision to interpret gestures or
movements.
• Combining these technologies enables
touchless interactions in various devices.

10. 1.Public Self services: Touchless
screens are used in information
kiosks at public places like
airports, museums, and shopping
centers to provide interactive and
hygienic information access.

11. 2.Healthcare: In medical settings,
touchless technology helps control
the spread of infections. It's
employed in interfaces for medical
equipment, patient records, and
diagnostic tools

12. Gaming: Touchless technology is
used in gaming consoles and
arcades, offering an immersive
gaming experience with gesture-
based controls.

13. Smart Homes: Touchless
interfaces are integrated into
smart home devices, allowing
users to control lighting,
thermostats, and other smart
home features with gestures

14. Education:Touchless
touchscreens are integrated
into interactive whiteboards
and educational displays,
promoting a more engaging
and hygienic learning
environment.

15. • Cleanliness: Touchless touchscreens help keep
things clean by letting you interact without
physically touching the screen, reducing the
spread of germs.
• Safety: They make things safer by minimizing
direct physical contact, which is especially
important in places like hospitals or during
health concerns.

16. • Lasting Longer: These screens might last longer
because they don't suffer as much wear and tear from
people touching them all the time
• Easy to Use: They're easy to use, allowing for gestures or
voice commands, which can be helpful for people with
difficulty using traditional touchscreens
• Fun and Creative: They can be fun and creative,
especially in games or interactive displays where you
can control things with gestures

17. • Cost: Implementing touchless technology can be
more expensive than traditional touchscreen
systems, potentially increasing the overall cost of
the device or system
• Complexity: Touchless systems can be more complex
to design and implement, requiring sophisticated
sensors and algorithms, which may result in increased
development time and challenges.

18. • Power Consumption: Some touchless technologies,
especially those using cameras or sensors, may
consume more power, impacting the device's battery
life, which is crucial for portable devices.
• Environmental Sensitivity: Certain touchless systems
may be sensitive to environmental factors like lighting
conditions, obstacles, or interference, affecting their
reliability in specific situations.
• Security Concerns: Touchless systems, particularly
those relying on facial recognition or biometric data,
may raise privacy and security concerns if not
implemented and secured properly.

19. • Researchers are making touchless screens better by
improving how they sense touch and studying how people
use them. They're focused on cleanliness, safety, and figuring
out where these screens work best. They're also looking at
costs, security, and finding new ways to make them more
accessible and environmentally friendly. Overall, the goal is
to make touchless technology easier, safer, and better for
everyone.

20. • Touchless touchscreens are getting cooler! They'll
soon recognize gestures even better and work with
fancy stuff like augmented reality.
• Everyone, from hospitals to cars, will use them
more for easy and fun experiences.
• Think holograms and super-smart voice commands.
Plus, they're focusing on being inclusive and eco-
friendly for a better future where our interactions
with computers are awesome and good for the
planet.

21. • In conclusion, touchless touchscreens are
changing how we interact with computers,
offering a hands-free and clean option.
They're used in healthcare, retail, and more,
making interactions convenient. Future
improvements might include better gestures
and cool features. Despite challenges, they're
set to keep making digital interactions easy
and fun.
