2. SMART SIGNAGE SYSTEM
• Smart signage system is a network of customizable
displays that can be controlled electronically using a
computer, allowing content to be changed remotely
for the most targeted messaging possible.
• Smart Signage supports many-to-many interaction by
allowing users obtaining content from the digital
display they are pointing at with their smart phones.

EXAMPLE OF SMART SIGNAGE SYSTEM

4. TYPES OF SIGNAGE SYSTEM
• Stand-alone Smart Signage
• Web-based Smart Signage
• IPTV-based Smart Signage

5. STAND ALONE SIGNAGE SYSTEM
It consists of a display and a computer.
The computer is not connected to a
network. The contents of the digital
display(s) will be controlled by this
computer. New display contents can be
installed using a USB memory stick or
other portable storage device. A simple
stand-alone digital sign might only
display a single fixed display of content
or it might change different parts of the
display based upon a static schedule.

6. WEB BASED SIGNAGE SYSTEM
In this type of digital
signage, the contents of the
signage/display can be
directly controlled by a local
web browser . All the
contents on the display(s)
can be easily controlled by
users/administrators from
anywhere on the network
that is able to reach this
device (either directly or
through a proxy).

7. IPTV BASED SIGNAGE SYSTEM
In the IPTV approach all of the
contents are distributed by a
streaming IPTV media server. In
this approach contents such as
video, graphics, animations,
images files, and web contents
are directly distributed from a
central media server to media
players attached to networked
displays. A central network
manager handles the task of
organizing, managing, and
distributing content to a media
player connected to each display.

8. GENERAL INTERACTIVE SMART SIGNAGE
SYSTEM ARCHITECTURE

9. GENERAL INTERACTIVE SMART SIGNAGE
SYSTEM ARCHITECTURE
Consist by three components:
1. Display: It represents a visualization equipment, which could be a at-
panel LCD unit, a screen with projector, a digital billboard, a LED matrix
display, a 3D display, a PC monitor, or any emerging excitable and
transparent display.
2. System: It is an embedded media playback and control system
with/without network connectivity that coordinates the display and
interactive modality.
3. Interactive modality: It is the technical method, physical scale and social
style such that users can interact with the displayed content.

10. SYSTEM ARCHITECTURE OF
SMART SIGNAGE
It consists of N
signage displays,
each connected to a
signage device, a
wireless router, a
content provider and
M smart phones.

11. WORKING OF SMART SIGNAGE SYSTEM
• The signage device controls the content displayed on the signage display
through a video output link.
• The signage devices transmit B/M data packets to the wireless router using
wireless data links .
• The wireless router relays these packets through a wireless data link to the
smart phones that have joined a particular B/M group, which is the same as
the one the signage devices have joined. The wireless router also is
responsible for fetching the content data and control sequence for the
signage devices from a content provider through an Internet data link and
forwards the information to the signage devices through wireless data links.
• Although the current system design uses Wi-Fi in the implementation, any
wireless standard supporting B/M radio signals is also applicable.
• The signage device downloads updated content for the display from a
content provider through the Internet access.

12. SMARTPHONE ORIENTATION AND SIGNAGE
DISPLAY ORIENTATION
• The smart phone orientation is the direction of the smart phone projected
on the same plane. The smart phone orientation is quantized by the azimuth
angle measured clockwise from the north direction to the smart phone
orientation.
• Smart phones have embedded orientation sensors, which measure the
postures of the smart phones in 3D space.
• The signage display orientation is defined as the direction that is
perpendicular to the signage display, and is pointing into the display
surface.
• When a user is standing in front of the signage display and pointing his/her
Smart phone at the signage display, the smart phone orientation aligns with
the signage display orientation, which means the signage display
orientation can be quantized by the same azimuth angle measured by the
smart phone.

DISPLAY ORIENTATION

14. CYBER-PHYSICAL BROADCAST/MULTICAST
PROTOCOL
• The cyber physical B/M protocol is designed to incorporate the
orientation information of the display.
• Using this protocol the system is synchronize the content on
the digital displays with the smart phones.
• It is preferable to buffer all the ``DRAGGABLE'' files on the
smart phones.

15. BROADCAST/MULTICAST
PROTOCOL DATA FRAME
Orientation header field is an integer indicating the azimuth angle n that represents
the signage display orientation.
Signage ID is a unique identication of the signage device; Showing ID is the
identication of the content being displayed on the signage display; Sending ID is the
identication of content carried in this data packet; Data Header includes the size of
the content with the specified Sending ID, the total number of packets of the sending
content and the sequence number of the data fragment of this content encapsulated in
this packet; Data payload contains the data fragment limited to the size of 1024
bytes.

16. SOFTWARE DESIGN FOR SIGNAGE
DEVICE

17. SOFTWARE DESIGN FOR SIGNAGE
DEVICE
• A signage device starts running, it first connects to the wireless access
point and then the program splits into two subroutines.
• Subroutine 1 accesses the Internet and constantly checks for updates for the
content changes pushed by the content provider.
• If there is an update, the signage device will download the new content and
corresponding control sequence to the local storage.
• Subroutine 2 joins a particular B/M group and continuously sends the
packets to this group.
• The packets have the same format defined by the orientation enabled
cyber-physical B/M protocol.
• Subroutine 2 also updates the content showing on the signage display
according to a play list generated from the control sequence downloaded
from the content provider.

18. SOFTWARE DESIGN FOR SMARTPHONE

19. SOFTWARE DESIGN FOR
SMARTPHONE
• The application on smart phone starts running, it first connects to the
wireless access point and joins the same B/M group as the signage devices,
and then the program splits into two subroutines.
• Subroutine 1 continuously listens to the packets in the B/M group, and
extracts header fields of Signage ID, Orientation, and Showing ID.
• Subroutine 2 uses the accelerometer data to detect a ``dragging'' hand
gesture, which is treated as the signal issued by the user to interact with the
digital sign.
• If the hand gesture is successfully detected, the application checks with the
orientation sensor data and the calculated azimuth angle ranges.
• Showing ID of the same sign, and checks whether the content with the
specified identication has been buffered in the local storage.
• If the content file is ready, the content will pop up on the smart phone's
display to complete the interaction process.

20. DETECTION OF ``DRAGGING'' HAND
GESTURE
The smart phone only
detects one simple dragging
gesture.
The tri-axis accelerometer
used to detect the dragging
gesture.

21. SYSTEM IMPLEMENTATION

22. SYSTEM IMPLEMENTATION
• Smart Signage system consists of a LCD TV as the signage display, a
programmed Vx Works-based embedded media playback system as the
signage device, and an IP-multicast enabled Wi-Fi wireless router.
• The wireless router is used by the signage device to multicast packets to
smart phones and access Internet.
• Software applications are implemented on Android and iOS smart phones.
• For Android platform, the association process of connecting to SSID and
joining multicast group is handled by software automatically.

23. IMPLEMENTATION OF THE``DRAGGING''
HAND GESTURE

24. IMPLEMENTATION OF THE``DRAGGING''
HAND GESTURE
• Step 1: Before a user performs a ``dragging'' gesture, the display on the
Smart phone shows ``Drag what you like'‘
• Step 2: After a ``dragging'' event is detected, a successful ``dragged''
content is displayed on the smart phone
• Step 3: Finally, the user performs follow-up actions to store and use or even
discard the ``dragged'' content.

28. APPLICATION
• Financial organizations: customers and employees up to date by
broadcasting a variety of information through digital signage at their branch
locations. In addition to important information, they can also promote their
products to increase their sales and improve their customers’ experience.
• Educational organizations: It improves campus communications and
facilities emergency notifications. It can inform students about upcoming
seminars, registration deadlines, exams, and sports activities.
• Airports & railway stations: Digital Signage provides information about
flights, trains or bus schedules, changes in schedules, arrival and departure
information, delays, and other information.
• Hotels & restaurants: Communication with hotel guests. Providing up to
date and useful information such as special offers, restaurant menus,
entertainment announcements and conference and seminar announcements.

29. CONCLUSION
Smart Signage, a ``DRAGGABLE' cyber-physical broadcast/multicast
(B/M) media system is proposed in this presentation. With a novel cyber-
physical B/M protocol that synchronizes the content on the digital displays
with the smart phones, it supports one-to-many interaction by allowing
multiple users acquiring content from one display with a ``dragging'' hand
gesture. With the embedded display orientation information in the same
protocol, Smart Signage supports many-to-many interaction by allowing
users obtaining content from the digital display they are pointing at with
their smart phones. Users' QoE which is characterized by the response time,
is carefully studied in this paper to guarantee the performance of this cyber-
physical interactive display system.
