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

TYPES OF SIGNAGE SYSTEM

• Stand-alone Smart Signage

• Web-based Smart Signage

• IPTV-based Smart Signage

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.

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).

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.

GENERAL INTERACTIVE SMART SIGNAGE

SYSTEM ARCHITECTURE

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.

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.

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.

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

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.

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.

SOFTWARE DESIGN FOR SIGNAGE

DEVICE

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.

SOFTWARE DESIGN FOR SMARTPHONE

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.

DETECTION OF ``DRAGGING'' HAND

GESTURE

The smart phone only

detects one simple dragging

gesture.

The tri-axis accelerometer

used to detect the dragging

gesture.

SYSTEM IMPLEMENTATION

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.

IMPLEMENTATION OF THE``DRAGGING''

HAND GESTURE

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.

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.

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.
