As digital technology develops, users create expectations for performance that may be violated when malfunctions occur. This project examined how priming expectations of technology performance (high v. low v. no) and experiences of technology malfunction (present v. not present) can influence feelings of frustration and performance on a task. A preliminary sample of 42 undergraduate participants completed a QR code scavenger hunt using the augmented reality mobile app, ARIS. Following the task, participants reported what they found for each scavenger hunt clue, their responses to failures in digital technology, and technology acceptance attitudes. Several factorial ANOVAs revealed a main effect for expectation on adaptive items of the RFDT scale and a main effect for malfunction on performance level. This suggests a potential contradiction between attitudes and behaviors when considering a common scenario involving technology.

The article presents an approach applied in the online training of pre-service teachers to acquire digital competence. The content of the concept of ‘digital competence’ in its sustainable and variable component is clarified. The understanding of ‘augmented reality’ to e-learning objects is presented. Two forms of ‘augmented reality’ have been proposed to visualize video information to a clarified concept. The first one is presented via a QR code for quick access and applicable for mobile learning. The other is provided by icons and is applicable to e-learning with a computer. It is believed that ‘augmented reality’ can differentiate students’ online learning according to the field-dependent and field-independent cognitive style and their preferences on the use of different digital learning devices.

Marker Based Augmented Reality requires files and resources that have to be loaded from storage such as a local machine or a web server. We proposed a resource-independent method of transmitting AR content by encoding resources such as 3D model files as QR code and using the QR code itself as the marker. The AR system does not need any online and local storage. We processed the content to best fit it into the QR code. Larger contents are then split to multiple QR codes and the data is joined together by the application on the other end.

Abstract This paper proposes an augmented reality (AR) framework and tool on smartphones as an alternative to conventional inspection for AM parts. The framework attempts to introduce the rapid inspection potential of smartphone based AR within manufacturing by leveraging the manufacturing capability of additive manufacturing (AM) to integrate markers onto AM parts. The key step from this framework that is explored in this paper is the design and quality assessment of AM markers for marker registration. As part of the marker design and quality assessment objectives, this research conducts an evaluation on the effects of different AM processes on the quality of augmentation achieved from AM fiducial markers. Furthermore, it evaluates the minimum fiducial pattern size that on integration onto AM parts will be viable for augmentation. The results suggest that the AM process and the size of the fiducial pattern play a significant role in determining the quality of the AM markers. The paper concludes by stating that dual material extrusion AM markers provide the highest number of detectable features and therefore the highest quality of AM markers, and the smallest viable fiducial pattern for Cybercode/QR code marker can be sized at 19 × 19mm2.

The choice of this work arises from the interest in the topics of innovation and technology transfer in the context of launching new services to target people. The authors sought to integrate a technology that could bring more interest to a product/service, namely with the modern growth of mobile activities and apps. Among some options considered, they chose the QR code technology. With the help of a strategic plan, they evaluate whether there is a market and propensity for its widespread use in Portugal. Then, an interactive prototype of the supporting platform is presented for its validation with users. Most participants know the QR code and consider the idea interesting and promising. They even suggested add-ons such as more video functions and a greater variety of events and resources for combining. Given the challenges of modern society, the authors recognize its eventual application to real-time requests for sharing specialized information or resources in critical activities of areas such as health and tourism. Features such as augmented reality, security, and privacy are future issues to address.
