The recent outbreak of COVID-19 has tremendously affected every aspect of global structures with its fast and lethal reach. Originating from Wuhan, a Chinese city, this highly infectious virus has forced to impose nationwide closures in many countries impacting onsite educational systems to shut down. Considering the safety of students and following other infected countries, the Bangladesh government has closed all the educational institutions until further notice. Although online teaching-learning is promoted for educators and students to streamline their educational activities from home, it has several drawbacks from different perspectives. Post pandemic scenarios in higher-level education system pose some questions and doubts which requires scholarly works for a thorough investigation. To analyze these scenarios and describe the trends towards effective teaching-learning, in this research work, we have proposed a model by interviewing students from the university level. Our proposed Model provides some rationale and guidelines for its post-pandemic implementation in the higher-level education system in Bangladesh.

The advancements in mixed reality (MR) technology in recent years have provided us with excellent prospects for creating novel approaches to supplement conventional physiotherapy to maintain a sufficient quantity and quality of rehabilitation. The use of MR systems to facilitate patients’ participation in intensive, repetitive, and task-oriented practice using cutting-edge technologies to enhance functionality and facilitate recovery is very encouraging. Multiple studies have found that patients who undergo therapy using MR experience significant improvements in upper limb function; however, assessing the efficacy of MR is challenging due to the wide variety of methods and tools used. Because of these challenges, a novel approach, gamified MR-based solution for upper extremity rehabilitation, is proposed, which is an MR application for the Microsoft HoloLens 2, complete with game levels, and can measure the ranges of motion of the arm joints. The proposed rehabilitative system’s functionality and usability were evaluated with ten healthy adult participants with no prior arm-related injuries and two occupational therapists (OTs). The system successfully provided rehab exercises for upper limb injuries through interactive mixed-reality games. The system can mimic upper limb behavior without additional sensors during rehab sessions. Unlike previously researched technologically-based rehabilitation methods, this method can integrate arm–joint data within the application and are independent of one another. The results and comparisons show that this system is relevant, accurate, and superior to previous VR-based rehabilitation methods because the VR-based system is blind to the surroundings, whereas the proposed approach has spatial awareness of the environment.
