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].

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].
