Development of Augmented Reality Application for Interactive Smart Materials

Abstract

The paper presents research related to thermochromic inks printed on textile materials. These types of materials are smart materials, they act as packaging indicators, and we use them to develop a software application on mobile devices. That application identifies the most significant changes in parameters of the goods contained in the packaging, such as temperature changes during the storage and transport (goods packaged in packaging that is sensitive to heat), or such as pharmaceuticals and frozen food, etc. This paper aims to demonstrate the possibility of connecting thermochromic materials and Augmented Reality technology through the development of an application for identifying thermochromic materials changes. The tested samples were printed on the textile with a screen printing technique with conventional and thermochromic leuco inks on various textile materials. The Augmented Reality platform Vuforia was used for developing a software application for mobile devices. The application was developed for the iOS mobile platform. The result of the research is the functional application that actively monitors and displays changes in thermochromic materials due to temperature changes, which identifies the effect of heat on the goods in textile packaging.

Innovative processes in smart packaging. A systematic review

“…With different sensitivities and with its strategically defined layout, the QR code is then printed in a way that overlaps with the TTI. Thus, with the use of a mobile phone or another device, it is possible to obtain the temperature reading of a product and to know if it is properly packaged 128 …”

“…In addition, it is possible to increase interaction with the consumer, to bring specific information about that product individually, or bring links from a website for more details about the product. Another example of its use is to identify whether a product has passed its expiration date quickly and efficiently through the mobile phone, or whether the product was packaged at the correct temperature 128 …”

“…Another example of its use is to identify whether a product has passed its expiration date quickly and efficiently through the mobile phone, or whether the product was packaged at the correct temperature. 128 Figure 16 displays a QR code associated with a TTI. The TTI has been printed with a chromatic thermo ink to become visible or invisible when the label is exposed to different temperatures.…”

“…Thus, with the use of a mobile phone or another device, it is possible to obtain the temperature reading of a product and to know if it is properly packaged. 128 Because it is a unique identification of the product, it can also be implemented to ensure authenticity and prevent fraud or robbery. Table 10 shows companies that offer the development and implementation of the QR code system.…”

“…9 In the packaging industry, smart packaging can be used in conjunction with augmented reality (AR) in a real-time, direct, or indirect view of the real world, which can be improved or increased by the addition of computer-generated information. 128 The use of AR in packaging can alter the consumer's experience with the product, and bring objective information such as price, origin, composition, nutritional value, authenticity, and discounts, among others. The consumer experience with the product can also contain subjective information, such as comments, reviews, and suggestions.…”
