It was the touch screens which initially created great foregone are the days when you have to fiddle with the touch screens and end scratching up. Touch screen displays are ubiquitous worldwide. Frequent touching a touchscreen display with a pointing device such as a finger can result in the gradual de-sensitization of the touchscreen to input and can ultimately lead to failure of the touchscreen. To avoid this a simple user interface for Touchless control of electrically operated equipment is being developed. Elliptic Labs innovative technology lets you control your gadgets like Computers, MP3 players or mobile phones without touching them. A simple user interface for Touchless control of electrically operated equipment. Unlike other systems which depend on distance to the sensor or sensor selection this system depends on hand and or finger motions, a hand wave in a certain direction, or a flick of the hand in one area, or holding the hand in one area or pointing with one finger for example. The device is based on optical pattern recognition using a solid state optical matrix sensor with a lens to detect hand motions. This sensor is then connected to a digital image processor, which interprets the patterns of motion and outputs the results as signals to control fixtures, appliances, machinery, or any device controllable through electrical signals.

Researchers have always tried to build a device capable of seeing people through walls. However, previous efforts to develop such a system have involved the use of expensive and bulky radar technology that uses a part of the electromagnetic spectrum only available to the military. Now a system is being developed by Dina Katabi and Fadel Adib, could give all of us the ability to spot people in different rooms using low-cost Wi-Fi technology. The device is low-power, portable and simple enough for anyone to use, to give people the ability to see through walls and closed doors. The system, called “Wi-Vi,” stands for "Wi-Fi" and "vision." is based on a concept similar to radar and sonar imaging. But in contrast to radar and sonar, it transmits a low-power Wi-Fi signal and uses its reflections to track moving humans. It can do so even if the humans are in closed rooms or hiding behind a wall.
Simple definition for Wi-Vi is, as a Wi-Fi signal is transmitted at a wall, a portion of the signal penetrates through it, reflecting off any humans on the other side. However, only a tiny fraction of the signal makes it through to the other room, with the rest being reflected by the wall, or by other objects. Wi-Vi cancels out all these other reflections, and keeps only those from the moving human body. Previous work demonstrated that the subtle reflections of wireless inter signals bouncing off a human could be used to track that person's movements, but those previous experiments either required that a wireless router was already in the room of the person being tracked. Wi-Fi signals and recent advances in MIMO communications are used to build a device that can capture the motion of humans behind a wall and in closed rooms. Law enforcement personnel can use the device to avoid walking into an ambush, and minimize casualties in standoffs and hostage situations. Emergency responders can use it to see through rubble and collapsed structures. Ordinary users can leverage the device for gaming, intrusion detection, privacy-enhanced monitoring of children and elderly, or personal security when stepping into dark alleys and unknown places.
The concept underlying seeing through opaque obstacles is similar to radar and sonar imaging. Specifically, when faced with a non-metallic wall, a fraction of the RF signal would traverse the wall, reflect off objects and humans, and come back imprinted with a signature of what is inside a closed room. By capturing these reflections, we can image objects behind a wall.
Wi-Vi is a see-through-wall technology that is low-bandwidth, low-power, compact, and accessible to non-military entities. Wi-Vi is a see-through-wall device that employs Wi-Fi signals in the 2.4 GHz ISM band.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. MULTITOUCH?
“In computing, multi-
touch refers to a touch
sensing surface's (track
pad or touchscreen) ability
to recognize the presence
of two or more points of
contact with the surface.”
4. Introduction
• Multi-touch technology presents a wide
range of new opportunities for interaction
with graphical user interfaces, allowing
expressive gestural control and fluid multi-
user collaboration through relatively simple
and inexpensive hardware and software
configurations.
5. Types
a) Capacitive Touch Technologies
b) Resistive Touch Technologies
c) Optical Touch Technologies
d) SAW Touch Technologies
e) Infrared Technologies
6. Capacitive
Touch Screen
Technology
A capacitive touch screen
consists of a glass panel
with a capacitive (charge
storing) material coating
its surface. Circuits
located at corners of the
screen measure the
capacitance of a person
touching the overlay.
But it only responds to
finger contact and will not
work with a gloved hand
or pen stylus.
7. Resistive Touch
Screen Technology
Resistive touch screen
technology consists of a glass or
acrylic panel that is coated with
electrically conductive and
resistive layers. The thin layers
are separated by invisible
separator dots. When operating,
an electrical current moves
through the screen. When
pressure is applied to the screen
the layers are pressed together,
causing a change in the electrical
current and a touch is registered.
8. Surface Acoustic
Wave (SAW)
SAW technology uses
ultrasonic waves that pass
over the touch screen panel.
When the panel is touched, a
portion of the wave is
absorbed. This change in the
ultrasonic waves registers the
position of the touch event
and sends this information to
the controller for processing.
It uses pure glass
construction, hence SAW
provides superior image
clarity, resolution and higher
light transmission compared
to resistive and capacitive
technologies.
9. Infrared
Infrared technology relies
on the interruption of an
infrared light grid in front
of the display screen. The
touch frame contains a
row of infrared LEDs and
photo transistors, each
mounted on two opposite
sides to create a grid of
invisible infrared light.
The frame assembly
comprises printed wiring
boards, on which the
electronics are mounted
and is concealed behind
an infrared-transparent
bezel.
10. Optical Touch
Optical imaging solution is one of
the more modern touch
technologies.
Since NextWindow's technology
uses optical sensors to detect the
touch point, the touch registers
just before the physical touch on
the screen. This means that users
can apply zero or light touch to
the screen to initiate a response,
and any input device, such as a
paintbrush, finger, pen, or stylus
will work.
Optical imaging provides a
solution without calibration drift.
13. Applications
• Our technique is force-sensitive, and provides
unprecedented resolution and scalability, allowing
us to create sophisticated multi-point widgets for
applications large enough to accommodate both
hands and multiple users.
14. Multi-Touch & Mobile

15. A New Approach
Frustrated Total Internal Reflection (FTIR):
• If another material touches that within
which the light is reflecting, the reflection is
frustrated, causing the light to escape.
• This has been used in the past:
• fingerprint imaging
• early touch sensors (1970s!)
• tactile sensors for robotic grips
16. Using FTIR for Touch Sensitivity
• A clear acrylic sheet is used as the touch
surface.
– 16 inches x 12 inches in prototype
• Edges of surface lit by infra-red LEDs to
produce total internal reflection.
• A video camera is mounted under the surface
and facing it.
• When the surface is touched, the light
escapes and registers on the camera.
17. Advantages to this Approach
• High capture rate and resolution
– 30 frames per second
– 640x480
• True zero-force touch sensitivity
• Inexpensive to construct
• Scalable to much larger (even wall-sized!)
surfaces
• Transparent: can be combined with rear-
projection display
18. The current use of multi-touch
technology
The current use of multi-touch technology enables users to easily interact
with various devices by simply using a touch screen and navigate through
interactive content with ease, ensuring great flexibility and speed.
Nowadays, users have the opportunity to use multi-touch display panels,
multi-touch displays windows, but also multi-touch tables and notebooks.
Some important players on the market of multi-touch solutions are Touch
Data LLC and GestureTek who are focused on the development of
comfortable and effective solutions such as the multi-touch wall or multi-
touch workstation.
Their products and solutions ensure the possibility of simultaneously
accommodating multiple users and individual use. Such solutions are
widely used in professional presentations and for broadcast use due to their
flexibility, speed, effective interactivity and great design.
19. The scope of multi-touch interaction
The multi-touch solutions will continue to evolve in
complexity and ease of use, and we will be main
beneficiaries of such multi-touch achievements.
More investments will be made in the field of multi-touch
technology as well as in the research papers conducted by
professional engineers in this area of expertise.
TouchData LLC. is also planning to revolutionize the
computer era through their multi-touch solutions by
ensuring a 100% natural user interaction with such devices.
Their solutions will be able to be implemented in many
fields such as engineering, tourism, academic, media,
marketing and also medical field.
20. Enhancement in Technology
In more recent work we focus on new multi-touch
paradigms and interactions that combine both traditional 2D
interaction and novel 3D interaction on a touch surface to form
a new class of multi-touch systems, which we refer to as
interscopic multi-touch surfaces (iMUTS). We discuss iMUTS-
based user interfaces that support interaction with 2D content
displayed in monoscopic mode and 3D content usually
displayed stereoscopically.
21. Market Trends
Figure shows the key aspects of
how user interfaces and
interaction technologies have
evolved over the past 50 years:
specifically, an increase in size
and number of units sold,
improvement in degree of
interactivity (from static batch
processing to intuitive interfaces)
and degree of integration with
other devices and technologies.
This evolution marks the
beginning of a transformational
shift, with the user experience
through computing form factors
superseding the effects of
product functionalities.
