I. INTRODUCTION
Figure 1. The application
scenario of IntelligShop.
Shopping is an important part of
our daily life and today’s vibrant
economy. According to the Year
2013 Singapore government report2,
among receipts totaling S$23.5 billion,
29% of them (∼S$6.85 billion)
are for shopping, food & beverage.
With the proliferation of smartphones
and ubiquitous supporting of
3G/4G/LTE networks, we have the
opportunity to enhance the shopping
experience through mobile technology.
In this paper, we demonstrate
IntelligShop, a novel location-based
augmented reality application, for intelligent
shopping in malls.
The key functionality of IntelligShop,
as shown in Figure 1, is to

provide an augmented reality interface
– people can simply use ubiquitous smartphones to
face the retailers (e.g., PastaMania and Starbucks), then
IntelligShop will automatically recognize the retailers (i.e.,
it is PastaMania or Starbucks) and bring their online reviews
from various sources (including blogs, forums and publicly
accessible social media) to display on the phones. It is
worth noting that, IntelligShop provides seamless locationbased
augmented reality, which makes the review obtaining
process much easier – the user now does not need to type
the retailer name or browse through some retailer catalog;
instead she just simply raises the phone camera against
the retailer for immediately getting its reviews displayed
at the right location. Technically, the retailer recognition
is achieved by the location and the orientation information
sensed by the phone, as well as the mall’s floor plan. We
highlight that, as we are dealing with the indoor environment,
we use the WiFi signals instead of GPS to do
the localization. Using WiFi signals for localization [4] is
popular, because unlike other localization technologies such
as iBeacon3 or image recognition [1], it is inexpensive and
can leverage existing infrastructure without new hardware.
