Impact of the textbooks’ graphic design on the augmented reality applications tracking ability

Abstract

Augmented reality (AR) is very effective in school education. Thus, a number of these applications are growing permanently. In most cases, these applications use school textbooks as target images for the AR technology. In developing a textbook design accompanied by the AR application, it is important to use such elements will ensure a stable tracking property when a gadget is held by a kid. There are also various graphic design elements as addition to texts and illustrations in modern textbooks. It is necessary to study how these elements ensure the tracking stability when conditions of textbook viewing are changing. The use of corner detectors to assess the tracking ability of different graphic elements in a textbook is considered. A comparative analysis of the tracking stability for textbook pages is carried out by means of the Harris-Stephens method, BRISK, FAST, Shi & Tomasi methods (also known as the minimum eigenvalue algorithm) which detect features and form their descriptors for the image. Results for these methods are collated with the tracking ability of targets used for a rating estimation on the basis of the Augmented Reality Platform Qualcomm Vuforia.
