Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. INTRODUCTION:
• Touch screen were responsible for creating a great future to the
technology at alarming rate
• The main problem while working with touch screen is scratching
up on the screen
• By frequently touching screen with the help of touching device or
with finger may cause a dullness or desensitization of the touch
screen and cause failure of touch screen
• A simple user interface being developed for touch less control of
electrically operated equipment
3
4. • Unlike the other system which gradually depend on the distance
from the sensor ,this interface depend on the finger motion or hand
wave in certain direction.
• The device is based on optical pattern recognition using optical
sensor with a lens to detect the hand motion
• the sensor is then connected to a digital image processor. This
interrupt the pattern of motion and output the result as signal to
control the application, machineries, or on any other device which
controllable through electrical signal
4
5. • This paper introducing about various touch less touch screen
technologies and its various type also introducing about one of the
implemented touch less touch screen technology
• With touch less touch screen our hand doesn’t have to come in
contact with the screen at all, it work by detecting our hand movement
in front of it.
• Most of the time we have to wipe the screen to get a better modest
view of the screen
• In this technology we have to simply point our finger in the air
towards the device and move it accordingly to control the navigation of
the device 5
6. What’s touch screen
• Touch screen is a electronic visual display that can detect the
presence and location of a touch with in the display area
• The term generally refers touching the display of the device with
finger or hand
• Touch screen are common in devices such as all in one computers
and smart phones
• Such display can be attached to a computer or to a network as
terminals
•Touch screen enables one to interact with what is displayed
directly on the screen where it is displayed rather than indirectly
with mouse or touchpad 6
7. •It lets one to do so without requiring any intermediate devices
that it would be in the hand
7
8. VARIOUS TECHNOLOGIES
Capacitive Touch Screen Technology
• it consist of an insulator such as glass,
coated with a transparent conductor such as
Indium Tin Oxide(ITO)
• As the human body is also an electrical
conductor, touching the surface of the
screen result in a distortion of screen’s
electric field measurable as a change in
capacitance
8
9. TYPES OF CAPACITIVE TOUCH SCREEN
• Surface capacitive technology
• in this basic technology only one side of the insulator is coated
with a conductive layer
•When a conductor, such as a human finger touches the uncoated
surface a capacitance is dynamically formed
•Location of the touch indirectly from the change in the capacitance
as measured from the four corner of panels
9
10. Projected capacitive technology
• projected capacitive touch(PCT) technology is a capacitive
technology which permit more accurate and flexible operation by
etching the conductive layer
•The greater resolution of PCT allows operation without direct
contact, such that the conducting layer can be coated with further
protective insulating layer and operates even under the screen
protectors
•Due to the top layer of a PCT being glass, PCT is a more robust
solution versus resistive touch technology
10
11. Advantages
• scratch resistant, durable surface
• very accurate
• liquid won’t affect touch screen performance
Disadvantages
• does not work with gloved finger
11
12. Resistive touch screen
•A resistive touch screen panel is composed of several layers, the
most important of which are two thin electrically conductive layers
separated by narrow gap
• when an object such as a finger presses down on a point on the
panel’s outer surface the two metallic layer become connected at
that point
•The panel then behave like as a pair of voltage dividers with
connected outputs
12
14. •The cover sheet consist of a hard outer surface with a coated inner
surface
•When the inner layer is touched it causes the conductive layer to
touch creating a signal that the analog controller can interpret and
determine what the user wants to be done
• Resistive touch is used in restaurants factories and hospitals due to
its high resistance to liquids and contaminants
14
15. Advantages
• Cost-effective solution
• Activated by any stylus
• Very accurate
• Low power requirements
• Liquids won't affect touch screen performance
Disadvantages
• Polyester surface can be damaged
15
16. Surface acoustic wave touch
• surface acoustic wave technology uses ultrasonic wave that
passes over the touch screen
• when the panel touches a portion of the wave is absorbed
• this change in the ultrasonic wave registers the position of the
touch event send this information to the controller for processing
• surface acoustic wave touch screen technology is based on
sending acoustic wave across a clear glass panel with a series of
transducers and reflectors
•When a finger touches the screen the wave are absorbed, causing
a touch event to be detected at that point
16
18. Advantages
• Durable glass construction
• High optical clarity
• Activated by a finger, gloved hand, or soft tip stylus
Disadvantages
• Moving liquids or condensation can cause false touches
• Solid contaminants create non-touch areas until removed
Doesn't support drag or draw effectively
18
19. Infrared touch technology
• Infrared touch screen rely on the interruption of an IR light grid
in front of the display screen
• An opt-matrix frame is integrated into the display bezel that
contain a row of LEDs and phototransistors each mounted on two
opposite side to create a grid of invisible light
• The opt-matrix frame is isolated from the outside environment by
an IR transparent barrier
• IR controller sequentially pulses the LEDs to create a grid of IR
light beam
19
20. • When a stylus enter a grid, it obstruct the beams, causing one or
more of transistors to detect the absence of light and transmit a
signal with x and y coordinates
20
21. Advantages
• Highest quality of underlying image
• Very high transmittance
• Excellent anti-glare, with use of chemically etched glass
• Can be activated with almost any device
• Higher accuracy than other technologies
• Very high durability and reliability
Disadvantages
• Surface obstructions can cause a false touch
• It is very sensitive and can be activated by stray touches.
• Low resolution
21
22. Construction
•In the most popular techniques, the capacitive and resistive
approach, there are typically four layers.
•Top polyester coated with the transparent metallic conductive
coating on the bottom
•Glass layer coated with a transparent metallic conductive coating
on the top
•Adhesive layer on the back side of the glass for mounting
•When the user touches the surface the system records the change
in the electrical current that flow through the display
22
23. •Dispersive signal technology which measures the piezo electric
effect the voltage generated when mechanical force is applied to a
material that occurs chemically when a strengthened glass substrate
is touched
•There are two infrared based approaches. In one, an array of sensors
detect a finger touching or almost touching the display, thereby
interrupting light beams projected over the screen, in other bottom-
mounted infrared cameras record screen touches
23
24. • Everybody likes a touch screen the experience is really exciting but
gradually the excitement started fading
• While using the phone with the finger tip the screen started getting a lot
of finger prints and scratches
• The system is capable of detecting movement in 3D without putting our
finger on the screen
• Their untested touch less interface(UI) doesn’t require special sensor
that we wear on our finger or either on our hand
• We have to just point at the screen and we can easily manipulate object
in 3D
TOUCH LESS TOUCH SCREEN
24
25. • It obviously require a sensor but the sensor is not hand mounted
• Sensor is placed either on the screen or near the screen
• The hardware setup is very compact
• Sensors are mounted around the screen
• By interacting with the line of sight of these sensors, the motion
is detected and interpreted into an screen movement
• Stop unintentional gestures are used as input
• The system is capable of detecting movement in 3D with out
putting finger on the screen
25
28. •It is designed for the application where touch may difficult
•Software translate the gestures into screen commands
•Technology detect motion in 3D and require no special worn
sensors for operation
•By simply point to the screen user can manipulate the object being
displayed in 3D
•The device is based on optical pattern recognition using a solid
state optical matrix sensor with a lens to detect hand motion
28
29. • The sensor is then connected to a digital image processor which
interpret the pattern of motion and outputs the result as signal to
control the applications.
29
30. GBUI(Gesture Based User Interface)
•It involve a lot of gestures which allow us to take application
and forward them to others with simple hand movement
30
31. TOUCH LESS UI
The basic idea patent in that there would be sensors arrayed around
the perimeter of the device capable of sensing finger movement in
3D space
31
33. •Software Development Kit
•A set of software development tool
•Touch less SDK is an open source for .NET application
•It enables developers to create multi touch based application
using webcam for input
•Using SDK developers offers users a new and a cheap way of
experiencing multi touch capabilities without the need of
expensive hardware or software
33
35. •It refers to the touch screen hardware setup itself
•The corresponding software to run touch wall which is built on a
standard version vista called plex
•Touch wall consist of three infra red lasers which scan a surface
•A camera notes when something breaks through the laser line and
feed that information back to the plex software
35
36. MINORITY REPORT INSPIRED TOUCHLESS
TECHNOLOGY
•Tobbii Rex
It is a eye tracking device from Sweden
•Elliptic lab
It allow us to operate our computer without touching it with the windows
8 Gesture suite 36
37. •Air writing
It is a technology that allows you to write text messages or compose emails by
writing in the air
•Eyesight
Eye sight is a gesture technology which allows you to navigate through
your devices by just pointing at it
37
38. •Mauz
Mauz is a third party device that turns over iPhone into a track pad or mouse
•Point Grab
Point Grab is something similar to eyesight, in that it enables users to
navigate on their computer just by pointing at it
38
39. •Leap motion
Leap motion is a motion sensor device that recognize the user’s finger with
infrared LEDs and cameras
•Microsoft kinect
It detect and recognize a user’s body movement and reproduces it within the
video game that is being played
39
40. LEAP MOTION TECHNOLOGY
•Leap motion controller provide an informative representation of
hands
•Leap motion controller is a new device developed for gesture
interaction by leap motion
•The device has small dimension of eight by three centimeter
•It is connected to the computer by USB, then user put hands on
the top of leap motion controller
•Leap motion controller detect the palm and finger movement on
top of it
•The tracking data which contain palm and finger position,
direction velocity it is accessed by using it’s SDK 40
41. DEVICE
•Leap motion controller is a new interactive device mainly
aiming at hand gestures and finger detection development by
leap motion
•There are three infra red light emitters and two camera which
receive the IR light
41
42. •Currently the newest version of the leap motion controller is
orion3.2.1
•Leap motion provides preprocessed data through their application
programming interface
•The data is accessed by a frame object queuing by per frame
•Based on the previews raw data we collected from leap motion
controller API they started to build feature to recognize hand
gestures
•These features are mainly divided into two
•Static gestures
•Dynamic gestures
42
43. STATIC GESTURES
•Features of static gestures are mainly built based on palm and
fingers relative distance
•We calculated two type of distances
•One type is the distance between fingers and palm center
•Other one is distance between two fingers which are adjacent
43
44. DYNAMIC GESTURE FEATURES
•Dynamic gesture features are distinguished from static gestures
•In this calculate the total velocity magnitude among fingers and
palm
•If the total movement value is greater than a user defined threshold,
it believe that hand is moving otherwise start recognizing the static
hand gesture
•Compared with static gesture pattern dynamic gesture patterns are
complicated
44
45. 45
•There are some cases when a leap motion controller fails to detect
all the finger
•One of that case is when fingers are self occluded by palms
•In this the leap motion controller is put below the palm and can not
get full data about the finger
•The leap motion controller use IR to gather hand information in the
space
•When important fingers or regions are self occluded by others hand
part tracking data quality reduced
46. ADVANTAGES
•Screen should be durable for a long period
•Screen always clean
•Touch area is minimized
•It make the work simplest
•In weather like rainy and winter hand being wet or with gloves,
won’t matter since the hand and finger movement is sensed by the
sensor
46
47. CONCLUSION
•Today's thoughts are again around user interface
•Efforts are being put to better the technology day in day out
•The touch less touch screen user interface can be used effectively
in computer, cell phone, webcam and laptop
•May be a few years down the line, our body can be transformed
into a virtual mouse, virtual key board
•Our body turned into an input device
