Augmented Reality in Food productiontraceability
INTRODUCTION
Traditionally, there are four basic functions of packaging:
to protect the product against the deteriorative effects of the external
environment, to communicate with the consumer as a marketing tool, to enable
easier usage of products, and to contain products of various sizes and shapes
[1]. However, recent changes in business requirements, technology development
and health regulations introduced the need for more advanced (intelligent)
functions of packaging – a packaging system that is capable of carrying out
intelligent functions (such as detecting, sensing, recording, tracing,
communicating, and applying scientific logic) to facilitate decision making in
orderto extend shelf life, enhance safety, improve quality, provide
information, and warn about possible problems [2]. Learn More The technical enablers for
mobile augmented reality (MAR) are becoming robust enough to allow the
development of MAR services that are truly valuable for consumers. Such
services would provide a novel interface to the ubiquitous digital information
in the physical world, hence serving in great variety of contexts and everyday
human activities [3]. The purpose of this article is to identify key elements
and design of a system for assessing the status of the content and history of
production process of a sealed food. The idea is to employ the AR technology as
one of the high promising and widely used technologies that enables information
storage in a different, more effective way and in a user friendly manner.
ON VIRTUAL AND AUGMENTED REALITY
Most popular definitions of virtual reality make
reference to a particular technological system. This system usually includes a
computer capable of real-time animation, controlled by a set of wired gloves
and a position tracker, and using a head-mounted stereoscopic display for
visual output [4]. Augmented Reality (AR) is a variation of Virtual
Environments (VE), or Virtual Reality (VR) as it is more commonly called. VE
technologies completely immerse a user inside a synthetic environment. While
immersed, the users cannot see the real world around them. In contrast, AR
allows the user to see the real world, with virtual objects superimposed upon
or composited with the real world. Therefore, AR supplements reality, rather
than completely replacing it [5]. The beginnings of AR, date back to
Sutherland’s work in the 1960s, which used a see-through Head Mounted Display
(HMD) to present 3D graphics. However, only over the past decade has there been
enough work to refer to AR as a research field [6]. AR is recognized at MIT as
one of ten emerging technologies of 2007, and we are at the verge of embracing
this very new and exciting kind of human computer interaction. AR technology is
currently used in a number of fields, such as medicine, education and simulated
training among others [10]. AR applications superimpose 3D and/or 2D graphics
on top of the real world view. This suggests that the available information can
be continuously updated through the design of new objects. In turn, these
objects and 2D graphics are inserted and handled by the AR applications with
the help of geo location data, or more recently AR tags, which can be easily
read by mobile devices and computers [11]. A.Mobile augmented reality AR has
traditionally been reserved for high-end computers while mobile augmented
reality (MAR) has used custom built hardware setups. Many of these consist of a
laptop mounted on a frame carried as a backpack. They often feature head
mounted displays (HMDs) and as such, the majority are research platforms
inaccessible to average consumers. Nowadays, smartphones have developed rapidly
and have enough rendering power to do 3D graphics [7]. Mobile AR is
particularly applicable whenever people require informational support for a
task while needing to stay focused on that task. It has the potential to allow
people to interact with computer-supported information (which might come from
databases or as a live feed from a remote expert), without getting distracted
from the real world around them. This is a very important feature for the
mobile worker, or for anybody who needs or wants to use their hands, and some
of their attention, for something other than controlling a computer [12].
B.Possibilities of MAR system Imagine a technology with which you could see
more than others see, hear more than others hear and perhaps even touch, smell
and taste things that others cannot. What if we had technology to perceive
completely computational elements and objects within our real world experience,
entire creatures and structures even that help us in our daily 1
activities, while interacting almost
unconsciously through mere gestures and speech? With such technology, mechanics
could see instructions what to do next when repairing an unknown piece of
equipment, surgeons could see ultrasound scans of organs while performing
surgery on them, firefighters could see building layouts to avoid otherwise
invisible hazards, soldiers could see positions of enemy snipers spotted by an
unmanned reconnaissance aircraft, and we could read reviews for each restaurant
in the street we’re walking in [8].
