ABSTRACT
COVID-19 pandemic has disrupted lives of most people in the world. Several measures have been implemented in many countries to restrict the spread of the virus, such as lockdowns, closure of schools and universities, and social distancing. Students and instructors in the Spring 2020 semester found themselves forced to move to online lectures in the middle of the semester. This paper reports the authors' experience of teaching software engineering in virtual classrooms at the beginning of COVID-19pandemic and the feedback of students who experienced the shift from traditional learning to online learning using interviews and online questionnaire. This paper presents also recommendations and lessons learned on how to engage with software engineering students in an online environment. Results showed that it is important to engage students both inside and outside the classroom for a successful virtual delivery of software engineering courses.
ABSTRACT
In the last decade, we have seen an increase in the use cases of digital technologies in our daily lives, including advanced systems such as our mobile applications, smart digital kiosks for intelligent retailing, touch screens for ordering food, or simple implementations such as the ticket machines in the butchers. However, from the perspective of interaction design, those sensing systems suffer from a range of limitations like low usability and poor hygiene. For example, the elderly or the disabled normally have huge difficulties when interacting with these types of digital systems. Moreover, the recent SARS-CoV-2 pandemic has made us to rethink the contact manner for interaction with the digital devices. Hence, in this paper, we have presented a novel solution for digital interaction through a contactless manner. Such a system can provide human gesture recognition and therefore it can be integrated into others to achieve contactless control. We have implemented a prototype based on cost efficient sensors to validate the idea’s feasibility. A sequence of real world experiments has also been conducted to evaluate its performance. This system is composed with 1) piece of hardware–a grid of ultrasound sensors to capture the distance information from a human body;2) a piece of software to analyse the data for gesture predictions. The analysis results then will be transformed into control commands to interact with the attached system. The experimental results have shown that the proposed system is capable of providing a contactless Human Computer Interaction (HCI), and also has a great opportunity to replace existing touching interaction manner with a remote control scheme.
