Using tangible user interfaces for teaching concepts of internet of things

Abstract

Purpose This paper aims to explore the use of tangible user interfaces for teaching concepts related to internet of things by focusing on two aspects, notably, usability and learning effectiveness. Design/methodology/approach To assess the usability of IoTTT, Nielsen’s principles were used due to its relevance and popularity for usability assessment. In the usability questionnaire, four attributes were evaluated, notably, learnability, efficiency, errors and satisfaction. As for evaluating learning effectiveness, learning assessment was conducted through pre-tests and post-tests. Two groups of 20 students participated where the first group attended conventional lectures on IoT, whereas the second group used IoTTT for learning same concepts. In the process, data was collected through the usability questionnaire and tests for usability and learning effectiveness assessment. Findings Results revealed a positive score for the usability of the TUI solution with an average rating of 3.9. Although this score demonstrated an acceptable solution, different issues were identified, based on which a set of recommendations have been made in this paper. On the other hand, in the common pre-tests, an average score of 6.40 was obtained as compared to a mean score of 7.33 in the post-tests for all participants. Knowledge gains were significantly higher for students who learnt IoT concepts through the TUI-based system where performance improved by 18 per cent. Originality/value The results revealed in this study are expected to help the research community, course designers and tutors comprehend the prospects of using tangible user interfaces to foster teaching and learning of IoT concepts. In addition, educational solution providers could consider commercialisation prospects of this technology to innovate in teaching and learning, while also building-up on limitations identified within this study.

Can gamification and interface design aesthetics lead to MOOCs' success?

“…Next, this study proved that students' perceived interface design aesthetics of MOOCs and continuance intention of MOOCs are two direct antecedents of their perceived impact on learning. The results support Nathoo et al 's (2020) study that has indicated that interface design aesthetics is critical as it has been found to shape the users' perceptions regarding the usability and learning effectiveness of a given IS/IT. The results reveal that students' perceived interface design aesthetics of MOOCs exhibits a greater direct impact on their perceived impact on learning (DE = 0.490) than their continuance intention of MOOCs (DE = 0.328) (see Table 7).…”

Economic Management Teaching Mode Based on Mobile Learning and Collaborative Learning

“…In this regard, we can combine the theoretical knowledge of teaching materials with modern information technology and means, and use modern information technology to provide the most up-to-date economic management information for classroom and teaching experiments [38]. In order to create a specific practice scene for students, the experimental teaching mode implemented by many majors at present has built a simulated small society for students by using IOT technology and virtual technology, created a simulated economic management environment and space, fully trained students' application and innovation of economic management knowledge, so as to improve their comprehensive practical ability [39,40].…”

Review: Development and Technical Design of Tangible User Interfaces in Wide-Field Areas of Application

“…and plastic figures with specific fiducial markers. The computer is the main component with software showing questions, learning text, and processing specific markers from tangibles by ReacTIVision, the TUI allows students to positively learn IoT in a creative and inspirational way [ 25 ].…”

“…ReacTIVision is an open-source platform for computer vision. It is used for the fast and robust tracking of fiducial markers placed on tangible objects and their identification in real-time [ 9 , 23 , 25 , 26 , 45 , 51 , 55 , 66 ]. The principle of the software is the binarization of the input images with an adaptive thresholding algorithm.…”
